Greetings, Next Tuesday, March 8 2022, is International Women’s Day, a day to celebrate women’s achievements and increase visibility whilst also calling out inequality. This year’s theme is “Break The Bias”, an opportunity to recognize and take action to level the playing field. Gender bias, discrimination and stereotyping are ever present obstacles facing women the world over. Whether it’s intentional or unconscious, it’s up to all of us to encourage and support a more diverse and inclusive society. You can learn more about International Women’s Day including, how to help Break The Bias, not just for a day, but permanently. Education is vital in our ever-changing and adapting world. At AUSCERT, we want to provide our members the opportunity to develop and strengthen their skills and contribute to a robust cyber security strategy. We have a list of online training courses for 2022, aimed at anyone that looks after cyber security. This training is exclusive for AUSCERT Members only for the price of $750 (inc. GST) per person, per training course. You can view the current dates of courses and book online here. Lastly, we want to acknowledge the devastating “rain bomb” that wreaked havoc on the east coast of Australia this week. The prolonged and immense rain has saturated our landscapes and left a trail of destruction with creeks and rivers turned into fast moving torrents. There are several services available to seek assistance or support our fellow Aussies in their time of need. If you need help or can lend a hand, below are a few organisations and initiatives that may suit your needs: GIVIT Vinnies Flood Appeal Brisbane Mud Army 2.0 ACSC on high alert following Russian attack on Ukraine Date: 2022-02-25 Author: Cyber Security Connect In the wake of Russian-linked cyber attacks on Ukraine, Prime Minister Scott Morrison and the Australian Cyber Security Centre (ACSC) have issued a warning to Australian organisations that malicious activity may have local ramifications. Similar warnings have been issued by the UK’s NCSC and the US Department of Homeland Security following recent sanctions on Russian institutions. As Australian society becomes increasingly digitised, agencies must prioritise measures to secure data and critical infrastructure against threat actors. Ukraine recruits “IT Army” to hack Russian entities, lists 31 targets Date: 2022-02-26 Author: Bleeping Computer Ukraine is recruiting a volunteer “IT army” of security researchers and hackers to conduct cyberattacks on thirty-one Russian entities, including government agencies, critical infrastructure, and banks. Saturday afternoon, Ukraine’s Minister for Digital Transformation Mykhaylo Fedorov announced that they need volunteer “digital talents” for an “IT Army” to conduct operational tasks against Russia on the cyber frontline. Google increasing account protections for users impacted by Russian invasion of Ukraine Date: 2022-03-01 Author: ZDNet Google detailed a series of measures it’s taking to help those impacted by the ongoing Russian invasion of Ukraine deal with associated cyber threats and privacy risks. In a lengthy Twitter thread, Google Europe ran through a list of measures it’s taking to automatically safeguard accounts, as well as measures users themselves can take to increase their privacy and security through freely available account features. First, the company made it clear that it is actively attempting to “look out for and disrupt disinfo campaigns, hacking, and financially motivated abuse” surrounding the conflict. This effort includes collaborations with other companies and “relevant government bodies” to address rising threats. Russia Sanctions May Spark Escalating Cyber Conflict Date: 2022-02-25 Author: Krebs on Security President Biden joined European leaders this week in enacting economic sanctions against Russia in response to its invasion of Ukraine. The West has promised tougher sanctions are coming, but experts warn these will almost certainly trigger a Russian retaliation against America and its allies, which could escalate into cyber attacks on Western financial institutions and energy infrastructure. Michael Daniel is a former cybersecurity advisor to the White House during the Obama administration who now heads the Cyber Threat Alliance, an industry group focused on sharing threat intelligence among members. Daniel said there are two primary types of cyber threats the group is concerned about potentially coming in response to sanctions on Russia. New ‘highly sophisticated’ malware linked to Chinese cyberattackers Date: 2022-03-02 Author: Citizen Digital A leading cybersecurity firm says it has discovered a “highly sophisticated” piece of malware being used by Chinese hacking teams to attack government and critical infrastructure targets. Symantec, a division of U.S.-based software designer and manufacturer Broadcom, said the earliest known sample of the malware, which has been dubbed Daxin, dates back to 2013, while Microsoft first documented the hacking tool in December 2013. A report by the company’s Threat Hunter Team says Daxin is “without doubt” the most advanced piece of malware it has seen used “by a China-linked actor.” The unit says Daxin was discovered along with other hacking tools previously used by Chinese cyberattackers.

Greetings, If you're involved in managing security awareness, your chance to make a difference is here with the SANS Security Awareness survey! AUSCERT has partnered with our friends at SANS on their 2022 SANS Institute Security Awareness Survey. You'll get early access to the free report and enter in a raffle to win a free pass to the Awareness Summit or an MGT433 course. The survey takes less than 10 minutes of your time but hurry, it closes today (February 25, 2022). Take the survey here Thanks in advance for your support! You’re invited to attend a critical Townhall session with the Department of Home Affairs on the Ransomware Action Plan and Proposed Reporting Regime. As part of Australia’s Ransomware Action Plan released last year, the Government is seeking to develop a ransomware incident reporting obligation for businesses – and is seeking your views on those proposed obligations. If you’re interested, register today so you don’t miss out! On a more sombre note, the much predicted and feared invasion of Ukraine by Russia became a reality yesterday. This attack has already demonstrated some twenty-first century tactics, including a concerted effort to disrupt the infrastructure of Ukraine through cyber-attacks. ABC reports on the various methods being utilised and the predicted escalation of their use and impact. This could extend to countries geographically distanced from the physical location of the conflict, including Australia. The Australian government has advised several companies had already been alerted to possible attacks, suggesting all should prepare for malicious attacks whether they’re direct or unintended or uncontained activities. AUSCERT Security Bulletin ASB-2022.0059 will soon be published and will provide advice and links regarding the current situation in Ukraine in relation to cybersecurity threats. This will include a list of IoCs (indicators of compromise) we have collated. We recommend members review these and consider searching or blocking threats accordingly.

Greetings, International Safer Internet Day took place on February 8, which was an opportunity for everyone to ensure they play it safe and fair online. There is no place for online abuse. We can all help to make life online enjoyable by being kind and respectful to each other. Research shows that Australians are learning and caring more about online safety than ever before and if you wish to learn more, visit the eSafety Commissioner website to help you to Play it Fair! The beginning of this week also saw Meta (formerly Facebook) lose a bid to dismiss legal action against them that related to the misuse of information of some of its Australian users. The social media giant was also flagged for not taking “responsible steps” to keep that information safe. This was the second time Meta’s request was denied following a ruling in late 2020 with authorities ruling that the company operated within Australia and collected data therein. Business Insider details the journey to the decision, made by the full bench of the Federal Court, which could have long-lasting and broad ramifications. Elsewhere, Telstra revealed plans to improve and increase its’ cyber security offerings to the Australian government. The pandemic has been identified as the catalyst for the increase in digital adoption which has also seen cyber attacks adapt and increase. itnews highlights how that, along with the government’s plans to centralise networks, are part of the reason for Telstra to create a specialised team to provide cyber security services at all levels of government.

Greetings, The beginning of February signified the Lunar New Year which in 2022, is the Year of the Tiger. Many Asian cultures historically follow a lunar calendar which sees the Lunar New Year fall on a different day than the (solar) Gregorian calendar. People born during a Tiger Year are thought to be natural leaders who are both brave and thrill-seeking, often craving attention. Some might say, these attributes are embodied by a lot of the competitors at this year’s Winter Olympic Games that officially gets underway tonight, in Beijing China. Though an exciting time for all taking part, the FBI has issued a warning to athletes to take a temporary, or burner, phone with them to mitigate risk of cyberattacks. NPR details the reason for this with all participants and officials required to download and use an app as part of the COVID-19 safety protocols. With over 450 million cyberattacks connected to the 2020 Tokyo Olympic and Paralympic games, the FBI is concerned the app would be a potential target for ransomware and malware, data theft, and distributed denial of service attacks. Elsewhere, a recent situation at Spotify has seen an exodus from the music streaming service. Subsequently, people across the globe have been looking at alternative platforms for their audio fixations with ZDNet providing a range of services to compare and evaluate to help in the decision-making process to get back to enjoying your favourite artists, songs and podcasts (including our very own ‘Share today, Save tomorrow’) 600K WordPress sites impacted by critical plugin RCE vulnerability Date: 2022-01-31 Author: Bleeping Computer Essential Addons for Elementor, a popular WordPress plugin used in over a million sites, has been found to have a critical remote code execution (RCE) vulnerability in version 5.0.4 and older. The flaw allows an unauthenticated user to perform a local file inclusion attack, such as a PHP file, to execute code on the site. "The local file inclusion vulnerability exists due to the way user input data is used inside of PHP's include function that are part of the ajax_load_more and ajax_eael_product_gallery functions." explains PatchStack researchers who discovered the vulnerability. Malicious hybrid cloud campaign uses 0Auth apps to target C-level executives Date: 2022-01-28 Author: SC Media Researchers reported a new hybrid cloud campaign — dubbed OiVaVoii — that uses hijacked Office 365 users and a sophisticated combination of malicious OAuth apps and targeted phishing threats to attack many C-level executives, including CEOs, general managers, former board members and the presidents of companies. In a Jan. 28 blog post, Proofpoint researchers said starting on Jan. 18, they observed account takeovers by malicious OAuth apps stealing OAuth tokens and via credential theft. The researchers said there are other risks after the account takeovers, mainly data leakage, continued phishing, lateral movement, brand abuse and malware distribution. NSW Police warns of new FluBot malware scam phishing texts Date: 2022-02-01 Author: Cyber Security Connect NSW Police posted a warning on their official Facebook page about the new FluBot phishing texts that have been making the rounds, sending malware links that enables download and installation of malicious software on to devices. According to Scamwatch, many Australians have been receiving scam text messages about missed calls, voicemails, deliveries and photo uploads since August 2021. The text messages ask recipients to tap on a link to download or access something. Doing so will download a specific type of malware to your device. These are “FluBot” text messages. Australian Red Cross clients potentially caught up in international cyber attack Date: 2022-01-31 Author: iTnews Australian Red Cross is contacting clients and reviewing its local systems and services in the wake of a “major” cyber attack on a large database hosted by the International Committee of the Red Cross (ICRC). The database held case file details on more than 500,000 people worldwide who had sought services for loved ones missing or uncontactable overseas due to disaster or conflict, or that were being held in immigration detention. Scammers continue to spoof job listings to steal money and data, FBI warns Date: 2022-02-02 Author: The Record Since at least early 2020, video game giant Riot Games has been dealing with a scam that is increasingly ensnaring companies and job seekers alike. According to a lawsuit filed by the company in November, a team of scammers “undertook an extensive, coordinated, and highly sophisticated fraud scheme” that lured eager professionals into handing over banking information and other sensitive data by dangling fraudulent job postings and interviews with fake human resources representatives. Similar scams have been reported by Biogen, Vox Media, Harvard University and many others. On Tuesday, the US Federal Bureau of Investigation warned that these scams have cost victims an average of [US]$3,000 since 2019, and often negatively impact their credit scores. The FBI’s Internet Crime Complaint Center (IC3) specifically alerted companies to a lack of strong security verification standards on recruitment websites, which allows criminals to post fake job ads.

Apple fixes new zero-day exploited to hack macOS, iOS devices Date: 2022-01-26 Author: Bleeping Computer Apple has released security updates to fix two zero-day vulnerabilities, with one publicly disclosed and the other exploited in the wild by attackers to hack into iPhones and Macs. The first zero-day patched today (tracked as CVE-2022-22587) [1, 2] is a memory corruption bug in the IOMobileFrameBuffer that affects iOS, iPadOS, and macOS Monterey. Successful exploitation of this bug leads to arbitrary code execution with kernel privileges on compromised devices. Over 90 WordPress themes, plugins backdoored in supply chain attack Date: 2022-01-21 Author: Bleeping Computer [Described in AUSCERT bulletin ESB-2022.0325, released Jan 24] A massive supply chain attack compromised 93 WordPress themes and plugins to contain a backdoor, giving threat-actors full access to websites. In total, threat actors compromised 40 themes and 53 plugins belonging to AccessPress, a developer of WordPress add-ons used in over 360,000 active websites. The attack was discovered by researchers at Jetpack, the creators of a security and optimization tool for WordPress sites, who discovered that a PHP backdoor had been added to the themes and plugins. Jetpack believes an external threat actor breached the AccessPress website to compromise the software and infect further WordPress sites. Google warns Aussie libel ruling could force it to censor search results Date: 2022-01-24 Author: iTnews Google has warned that it could be forced to “censor” search results if an Australian court ruling, which found it liable for defamatory material contained in hyperlinks, is not overturned. The web giant made the comments in submissions to the High Court, where it is appealing a defamation ruling that saw $40,000 in damages awarded to prominent Victorian criminal lawyer George Defteros. Staying insurable for your cyber security insurance policy Date: 2022-01-25 Author: Consultancy As the risk of cyber threats and its impact continues to rise, insurance companies are tightening their policy conditions. Murray Mills, a Manager at Tecala, outlines what Australian organisations can do to stay insurable against the threat of ransomware and other attacks. Growing increasingly tired of the operating environment, and in particular, the never-ending flood of ransomware infections, are the insurers whose role it often is to help victim organisations pick up the pieces and pay for much of the damage done. In 2022 changes to how insurers assess risk and determine premiums and coverage could become a problem for some organisations. Prime Minister Scott Morrison’s WeChat account is hijacked and renamed Date: 2022-01-24 Author: ABC News Senior Coalition MPs have accused China’s government of foreign interference after the Prime Minister’s account on the ubiquitous Chinese language messaging app WeChat was hijacked. As first reported by NewsCorp Australia, Scott Morrison’s account on the massive Chinese social media platform WeChat has been renamed and the account description changed. Singapore gives banks two-week deadline to fix SMS security Date: 2022-01-20 Author: The Register A widespread phishing operation targeting Southeast Asia’s second-largest bank – Oversea-Chinese Banking Corporation (OCBC) – has prompted the Monetary Authority of Singapore (MAS) to introduce regulations for internet banking that include use of an SMS Sender ID registry. Singapore banks have two weeks to remove clickable links in text messages or e-mails sent to retail customers. Furthermore, activation of a soft token on a mobile device will require a 12-hour cooling off period, customers must be notified of any request to change their contact details, and fund transfer threshold will by default be set to SG$100 ($74) or lower. How I Got Pwned by My Cloud Costs Date: 2022-01-24 Author: Troy Hunt I have been, and still remain, a massive proponent of “the cloud”. I built Have I Been Pwned (HIBP) as a cloud-first service that took advantage of modern cloud paradigms such as Azure Table Storage to massively drive down costs at crazy levels of performance I never could have achieved before. I wrote many blog posts about doing big things for small dollars and did talks all over the world about the great success I’d had with these approaches. One such talk was How I Pwned My Cloud Costs so it seems apt that today, I write about the exact opposite: how my cloud costs pwned me. It all started with my monthly Azure bill for December which was way over what it would normally be. It only took a moment to find the problem. Linux version of LockBit ransomware targets VMware ESXi servers Date: 2022-01-26 Author: Bleeping Computer LockBit is the latest ransomware gang whose Linux encryptor has been discovered to be focusing on the encryption of VMware ESXi virtual machines. The enterprise is increasingly moving to virtual machines to save computer resources, consolidate servers, and for easier backups. Due to this, ransomware gangs have evolved their tactics to create Linux encryptors that specifically target the popular VMware vSphere and ESXi virtualization platforms over the past year. ESB-2022.0329 – chromium: Multiple vulnerabilities Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure ESB-2022.0346 – ipython: Execute arbitrary code/commands – Existing account A potential arbitrary code execution vulnerability discovered in IPython (the interactive Python shell) ESB-2022.0352 – polkit: Increased privileges – Existing account Polkit vulnerability provides increased privileges on Linux systems ESB-2022.0399 – ALERT macOS Monterey 12.2: Multiple vulnerabilities Apple releases multiple updates including for macOS Monterey 12.2 ASB-2022.0048 – AUSCERT Bulletin Impact /Access Assessment to CVSS Migration AUSCERT’s own Impact and Access Assessment is being replaced by the industry standard CVSS score in our Security Bulletins Service.

Greetings, Last week’s undersea volcanic eruption near Tonga has impacted the island nation in several ways, including upon the submarine cables on which Tonga relied to connect to the world which is expected to take at least four weeks to repair. The eruption ruptured the single fibre cable, one of 280 across the globe, responsible for more than 95% of global data transfer. The Conversation highlights the vulnerable state of the network and, suggests how to potentially mitigate risk moving forward, in order to protect the 1.3 million kilometres (approx.) of cables. Time is running out to get your submission in for the AUSCERT2022 conference. The call for presentations and tutorials closes on January 30 and we’re on the lookout for unique topics, extraordinary projects or perhaps a clever way of optimising processes. So if you, or someone you know, has something to say and would like to share it, complete your submission online. AUSCERT is also able to assist in covering the travel and accommodation costs for one speaker per successful submission (conditions apply). Red Cross begs hackers not to leak data of “highly vulnerable people” Date: 2022-01-19 Author: The Record The Red Cross has disclosed that it was the victim of a cyber attack and has asked the hackers who broke into the IT network of one of its contractors not to leak the personal information of more than 515,000 of “highly vulnerable people.” The data was stolen from a Red Cross program called Restoring Family Links, which aims to reunite family members separated by conflict, disaster, or migration. “While we don’t know who is responsible for this attack, or why they carried it out, we do have this appeal to make to them,” said Robert Mardini, director-general for the International Committee of the Red Cross. Singapore monetary authority threatens action on bank over widespread phishing scam Date: 2022-01-18 Author: The Register The Monetary Authority of Singapore says it is considering supervisory action against Southeast Asia's second largest bank, Oversea-Chinese Banking Corporation, which was criticised for its incident response to a widespread phishing scheme across the island nation. "Monetary Authority Singapore takes a serious view of the recent phishing scams involving OCBC Bank. They have significantly impacted several customers. OCBC has acknowledged that its incident response and customer service should have been better. MAS has been following up with the bank on these and broader issues relating to the incident," said MAS deputy managing director Ms Ho Hern Shin in a statement to The Register. Bunnings customers’ personal data compromised following cyber attack Date: 2022-01-17 Author: Cyber Security Connect Bunnings Warehouse customers who shopped using the contactless pick-up service may have had some of their personal information stolen. The company has emailed customers to say they have recently been made aware of a data security breach experienced by its third-party booking provider FlexBooker. In December of 2021, the third-party software firm suffered a cyber security breach that led to the information of 3.7 million customers being exposed, and last week Bunnings was forced to warn its customers of the incident. The compromised information may have included customers' names and email addresses, which were provided when they selected a timeslot for a drive and collect order. ASB-2022.0046 – Oracle Java SE: Multiple vulnerabilities Oracle released their 3-monthly critical patches this week. Many products were patched.

Greetings, There are happenings taking place that are giving many of us the sense of déjà vu or a feeling as though a prolonged situation seemingly has no end. One such challenge is the constant presence and threat of Log4j. Labelled a ‘severe risk’ to the internet by some outlets, it continues to be utilised by parties that aim to exploit the vulnerabilities for their own gain. ZDNet recently reported on one that saw a cybercrime group attempting to deploy NightSky ransomware, highlighting the need to remain vigilant whilst these particularly problematic vulnerabilities remain. Log4j was also a significant contributor to the increase in cyber-attacks in 2021. Tech Republic provides an insight into the industries and locations that were most affected last year, with some sectors and countries seeing a increase of over 50% from 2020. Whilst it may seem that we’re experiencing Groundhog Day or some aspects of our lives are moving at a glacial pace, individuals and organisations shouldn’t look past the importance of taking stock of current processes and requirements and ask, “Can this be done better?”. Business Reporter published an article earlier this week that looks at the significance of seeking out and embracing change, when and where appropriate. This is especially relevant in our modern world and, in an industry with one significant constant – change. Microsoft: powerdir bug gives access to protected macOS user data Date: 2022-01-10 Author: Bleeping Computer Microsoft says threat actors could use a macOS vulnerability to bypass Transparency, Consent, and Control (TCC) technology to access users' protected data. TCC is security tech designed to block apps from accessing sensitive user data by allowing macOS users to configure privacy settings for the apps installed on their systems and devices connected to their Macs, including cameras and microphones. Apple fixed the vulnerability in security updates released last month, on December 13, 2021. Microsoft: New critical Windows HTTP vulnerability is wormable Date: 2022-01-11 Author: Bleeping Computer Microsoft has patched a critical flaw tagged as wormable and found to impact the latest desktop and server Windows versions, including Windows 11 and Windows Server 2022. The bug, tracked as CVE-2022-21907 and patched during this month's Patch Tuesday, was discovered in the HTTP Protocol Stack (HTTP.sys) used as a protocol listener for processing HTTP requests by the Windows Internet Information Services (IIS) web server. Report: Increased Log4J exploit attempts leads to all-time peak in weekly cyberattacks per org Date: 2022-01-11 Author: ZDnet Cybersecurity firm Check Point Research has released new data from 2021 showing that among their customers, there was a significant increase in overall cyberattacks per week on corporate networks compared to 2020. Researchers attributed some of the increases, which were concentrated toward the end of the year, to the Log4J vulnerability discovered in December. Check Point said in a report that 2021 was a record-breaking year for cyberattacks and the Log4J vulnerability only made things worse. Indian Patchwork hacking group infects itself with remote access Trojan Date: 2022-01-11 Author: ZDNet An Indian threat group's inner workings have been exposed after it accidentally infected its own development environment with a remote access Trojan (RAT). Dubbed Patchwork by Malwarebytes and tracked under names including Hangover Group, Dropping Elephant, Chinastrats, and Monsoon, the Indian group has been on the scene since at least 2015 and is actively launching campaigns designed to deploy RATs for the purposes of data theft and other malicious activities. In one of the latest attack waves connected to Patchwork, the group targeted individual faculty members from research institutions specializing in biomedical and molecular sciences. Ransomware: Hackers are using Log4j flaw as part of their attacks, warns Microsoft Date: 2022-01-11 Author: ZDNet Microsoft has confirmed that suspected China-based cyber criminals are targeting the Log4j 'Log4Shell' flaw in VMware's Horizon product to install NightSky, a new ransomware strain that emerged on December 27. The financially motivated ransomware attacks target CVE-2021-44228, the original Log4Shell flaw disclosed on December 9, and mark one new threat posed by the critical vulnerability that affects internet-facing software, systems and devices where vulnerable versions of the Java-based Log4j application error-logging component are present. Who is the Network Access Broker ‘Wazawaka?’ Date: 2022-01-12 Author: Krebs on Security In a great many ransomware attacks, the criminals who pillage the victim’s network are not the same crooks who gained the initial access to the victim organization. More commonly, the infected PC or stolen VPN credentials the gang used to break in were purchased from a cybercriminal middleman known as an initial access broker. This post examines some of the clues left behind by “Wazawaka,” the hacker handle chosen by a major access broker in the Russian-speaking cybercrime scene. ESB-2022.0097 – ALERT HP-UX telnetd: Execute arbitrary code/commands – Remote/unauthenticated Hewlett Packard Enterprise has issued an UN-OF point fix to address the Remote Execution of Arbitrary Code vulnerability in HP-UX telnetd. ASB-2022.0002 – ALERT Microsoft Windows, Windows Server, Remote Desktop Client and HEVC Video Extensions: Multiple vulnerabilities Microsoft's Patch Tuesday for January included fixes to resolve 87 vulnerabilities across various Microsoft products including Windows and Windows Server. ESB-2022.0111 – Acrobat, Acrobat DC, Adobe Reader and Adobe Reader DC: Multiple vulnerabilities Adobe's most recent security updates for Adobe Acrobat and Reader for Windows address multiple vulnerabilities. Adobe recommended its users to update their software installations to the latest versions.

A reminder to those that may have a great story to tell, or know someone else that does, the Call for Presentations for the AUSCERT2022 Conference is NOW OPEN. The Conference will be held as a hybrid event from Tuesday, 10th May – Friday, 13th May 2022 at The Star Gold Coast, Broadbeach and online via the OnAIR Virtual Conferencing Platform. You must submit by Monday, 10 January to receive feedback from our committee for further improvements before the final deadline of 30 January. Submit to our AUSCERT2022. Call for Presentations and Tutorials, due in January 2022. An interesting article featured on the info security website from earlier in the week predicts some of the trends for the Cyber Security sector in 2022. Specifically, it looks at Resilience, Secure by Design, Skills and Technology and offers some food for thought regarding our ever-evolving digital landscape. Google Chrome update includes 37 security fixes Date: 2022-01-06 Author: ZDNet [See AUSCERT Bulletin ASB-2022.0049, published January 06.] Google rolled out an update for Chrome this week on Windows, Mac and Linux that included 37 security fixes, one of which was rated critical. Google Chrome’s Prudhvikumar Bommana thanked dozens of security researchers for helping them find bugs, many of which were given a high severity rating. Chrome 97.0.4692.71 includes fixes for CVE-2022-0096 — a critical use-after-free (UAF) vulnerability — as well as other UAFs like CVE-2022-0098, CVE-2022-0099, CVE-2022-0103, CVE-2022-0105 and CVE-2022-0106. There are also three heap buffer overflow issues rated high severity. Detecting Evasive Malware on IoT Devices Using Electromagetic Emanations Date: 2022-01-03 Author: The Hacker News Cybersecurity researchers have proposed a novel approach that leverages electromagnetic field emanations from the Internet of Things (IoT) devices as a side-channel to glean precise knowledge about the different kinds of malware targeting the embedded systems, even in scenarios where obfuscation techniques have been applied to hinder analysis. With the rapid adoption of IoT appliances presenting an attractive attack surface for threat actors, in part due to them being equipped with higher processing power and capable of running fully functional operating systems, the latest research aims to improve malware analysis to mitigate potential security risks. FTC threatens legal action over unpatched Log4j systems Date: 2022-01-05 Author: The Register The US Federal Trade Commission on Tuesday warned companies that vulnerable Log4j software needs to be patched … or else. […] The FTC is advising companies to consult the US Cybersecurity and Infrastructure Security Agency’s (CISA) guidance on dealing with the Log4j flaws. If companies fail to fix their code and lose customer data, the FTC says it may just see what a judge thinks about that. The biggest data breaches, hacks of 2021 Date: 2022-01-01 Author: ZDNet In 2021, thousands of new cybersecurity incidents have been recorded — and while cryptocurrency theft and data loss are now commonplace, this year stands out due to several high-profile incidents involving ransomware, supply chain attacks, and the exploitation of critical vulnerabilities. The Identity Theft Research Center (ITRC) has reported an increase of 17% in the number of recorded data breaches during 2021 in comparison to 2020. However, an entrenched lack of transparency around the disclosure of security incidents continues to persist — and so this may be a low ball estimation. Don’t copy-paste commands from webpages — you can get hacked Date: 2022-01-03 Author: Bleeping Computer Programmers, sysadmins, security researchers, and tech hobbyists copying-pasting commands from web pages into a console or terminal are warned they risk having their system compromised. A technologist demonstrates a simple trick that’ll make you think twice before copying and pasting text from web pages. ASB-2021.0244.6 – UPDATED ALERT log4j: Multiple vulnerabilities Apache has released updates for log4j2 to address CVE-2021-44832 fixing another remote code execution vulnerability ESB-2022.0028 – wireshark: Multiple vulnerabilities Several vulnerabilities leading to a remote code execution or denial of service have been fixed in Wireshark ESB-2022.0042 – VMWare products: Execute arbitrary code/commands – Existing account VMWare has addressed a heap-overflow vulnerability affecting multiple products ESB-2022.0049 – Google Chrome: Multiple vulnerabilities Google has now released Chrome 97 which also addresses multiple security vulnerabilities including a critical vulnerability: CVE-2022-0096 which leads to a remote code execution ESB-2022.0059 – Tenable.sc: Multiple vulnerabilities Tenable has released Tenable.sc 5.20.0 to address multiple vulnerabilities including a critical vulnerability related to Apache HTTP server Stay safe, stay patched and have a good weekend!

AUSCERT Week in Review for 17th December 2021 Greetings, With only seven sleeps until Christmas, the realisation that the end of the year being upon us has well and truly set in! A reminder of our scheduled shutdown over the Christmas and New Year period: AUSCERT will be closed from Thursday, December 23rd until Monday, January 3rd 2022. We will reopen on Tuesday, January 4th 2022. The auscert@auscert.org.au mailbox will not be monitored during this period. However, we will staff the 24/7 member incident hotline as usual; so do call us for any urgent matters during this period. If you’re looking for something to do over the break, don’t forget the Call for Presentations for AUSCERT2022 is OPEN! We’re looking for something unique, a great story or, something new that can be shared with our attendees. The closing date for submissions is January 10th so be sure to get your idea to our committee to ensure feedback can be provided by the final deadline of January 30th. Also AUSCERT is hiring, so if you’re interested in infrastructure, putting together security solutions and working collaboratively with cyber security analysts, brush off your resume and send it to us over the break! Something that we have been reminded of this past week with Log4J, is that the world of cyber doesn’t have holidays and we must always remain vigilant. A recent blog from Seriously Risky Business provides a great overview of the situation and suggests how future occurrences of similar incidents can be avoided. Another blog post, this time from Rapid 7, highlights how threat actors seek to take advantage of large scale vulnerabilities such as Log4J, often working just as hard as those trying to remedy the situation, but with the aim to exploit the vulnerability. As this is the last Week In Review before Christmas, and with a lot of folk switching off for a well-earned break, the team at AUSCERT wanted to wish everyone a safe and happy Christmas and Festive Season and all the very best for 2022. Guidance for preventing, detecting, and hunting for CVE-2021-44228 Log4j 2 exploitation Date: 2021-12-11 Author: Microsoft Security Blog [This article is focused on the use of Microsoft security products to mitigate exploits. See also ASB-2021.0244.2, published December 10.] Microsoft’s unified threat intelligence team, comprising the Microsoft Threat Intelligence Center (MSTIC), Microsoft 365 Defender Threat Intelligence Team, RiskIQ, and the Microsoft Detection and Response Team (DART), among others, have been tracking threats taking advantage of CVE-2021-44228, a remote code execution (RCE) vulnerability in Apache Log4j 2 referred to as “Log4Shell”. The vulnerability allows unauthenticated remote code execution, and it is triggered when a specially crafted string provided by the attacker through a variety of different input vectors is parsed and processed by the Log4j 2 vulnerable component. For more technical and mitigation information about the vulnerability, please read the Microsoft Security Response Center blog. Bugs in billions of WiFi, Bluetooth chips allow password, data theft Date: 2021-12-13 Author: Bleeping Computer Researchers at the University of Darmstadt, Brescia, CNIT, and the Secure Mobile Networking Lab, have published a paper that proves it’s possible to extract passwords and manipulate traffic on a WiFi chip by targeting a device’s Bluetooth component. Modern consumer electronic devices such as smartphones feature SoCs with separate Bluetooth, WiFi, and LTE components, each with its own dedicated security implementation. Second Log4j vulnerability discovered, patch already released Date: 2021-12-15 Author: ZDNet A second vulnerability involving Apache Log4j was found on Tuesday after cybersecurity experts spent days attempting to patch or mitigate CVE-2021-44228. The description of the new vulnerability, CVE 2021-45046, says the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was “incomplete in certain non-default configurations.” “This could allow attackers… to craft malicious input data using a JNDI Lookup pattern resulting in a denial of service (DOS) attack,” the CVE description says. Why Companies Shouldn’t Shame Employees Who Fall for Hacking Scams Date: 2021-12-06 Author: Wall Street Journal [This article may be behind a paywall for some readers] The implications of our survey were clear: Shame is similar to a boomerang that will come back to hurt the organization, as well as harming the employee. Managers should deal with the mistake, but not reject the employee. If employees feel that their personhood is being attacked, they will respond defensively. Shaming results in a lose-lose outcome. Employees can be an organization’s greatest asset when it comes to defeating the efforts of cybercriminals. Using shame as a behavior modification tool squanders that potential. And that’s the real shame. Google pushes emergency Chrome update to fix zero-day used in attacks Date: 2021-12-13 Author: Bleeping Computer Google has released Chrome 96.0.4664.110 for Windows, Mac, and Linux, to address a high-severity zero-day vulnerability exploited in the wild. “Google is aware of reports that an exploit for CVE-2021-4102 exists in the wild,” the browser vendor said in today’s security advisory. Although the company says this update may take some time to reach all users, the update has already begun rolling out Chrome 96.0.4664.110 worldwide in the Stable Desktop channel. Actively Exploited Microsoft Zero-Day Allows App Spoofing, Malware Delivery Date: 2021-12-14 Author: Threat Post Microsoft has addressed a zero-day vulnerability that was exploited in the wild to deliver Emotet, Trickbot and more in the form of fake applications. The patch came as part of the computing giant’s December Patch Tuesday update, which included a total of 67 fixes for security vulnerabilities. The patches cover the waterfront of Microsoft’s portfolio, affecting ASP.NET Core and Visual Studio, Azure Bot Framework SDK, Internet Storage Name Service, Defender for IoT, Edge (Chromium-based), Microsoft Office and Office Components, SharePoint Server, PowerShell, Remote Desktop Client, Windows Hyper-V, Windows Mobile Device Management, Windows Remote Access Connection Manager, TCP/IP, and the Windows Update Stack. Australia to establish youth advisory council for countering online child exploitation Date: 2021-12-15 Author: ZDnet Australia will create a new panel consisting of Australian youths and young adults that will provide consultation to industry and government about how to approach regulating online platforms. “Young people know better than anyone about the good, the bad and the plain ugly that exists in the online world,” Prime Minister Scott Morrison said. “They are the first generation of Australians to grow up living simultaneously in both the real and digital worlds, and they are always at the forefront of new technologies. Visa pilots enumeration attack prevention requirement in Australia Date: 2021-12-15 Author: IT News Visa has chosen Australia as the first country worldwide where all “e-commerce payment providers” must have botnet detection capabilities in place by October to mitigate the threat posed by enumeration attacks. The payments giant said it could not fight a rise in enumeration attacks alone and needed the assistance of the entire payments ecosystem.

Submit by 10 January to receive feedback from our committee for further improvements before the final deadline of 30 January. AUSCERT was proud to be a Bronze sponsor of the 2021 Australian Women in Security Awards which were handed out earlier this week. Once a year, the security industry gathers to celebrate and raise the profile of the Australian IT Security, Cyber, and Protective Security industry to inspire young women and men to consider a career in this sector. This is done by honouring their accomplishments, value, and contributions to the Australian market and giving the recognition they deserve. This week, it was announced that Queensland borders would open to the rest of Australia on Monday, December 13 at 1:00am. As part of the ongoing focus on community safety, we’re all being reminded and encouraged to check-in when out and about in the community. With the growth in the number of phishing messages delivered to smart phones, it’s imperative to use the official apps from respective government bodies when visiting venues and using services (such as ride share). Queensland government energy generator says ransomware attack not state-based Date: 2021-12-09 Author: ZDNet Queensland government-owned energy generator CS Energy provided an update on Wednesday that those behind its November ransomware incident was unlikely to be a state-based actor. On the same morning, Sydney’s Daily Telegraph landed with a front page claiming China was behind the incident. Thanks to the appearance of CS Energy on a leak site listing victims of Conti ransomware run by the Wizard Spider group for the purposes of double extortion, the claims made by News Limited would appear to be unfounded. Emotet now drops Cobalt Strike, fast forwards ransomware attacks Date: 2021-12-07 Author: Bleeping Computer In a concerning development, the notorious Emotet malware now installs Cobalt Strike beacons directly, giving immediate network access to threat actors and making ransomware attacks imminent. Emotet is a malware infection that spreads through spam emails containing malicious Word or Excel documents. These documents utilize macros to download and install the Emotet Trojan on a victim’s computer, which is then used to steal email and deploy further malware on the device. Historically, Emotet would install the TrickBot or Qbot trojans on infected devices. These Trojans would eventually deploy Cobalt Strike on an infected device or perform other malicious behaviour. SolarWinds hackers have a whole bag of new tricks for mass compromise attacks Date: 2021-12-07 Author: Ars Technica Almost exactly a year ago, security researchers uncovered one of the worst data breaches in modern history, if not ever: a Kremlin-backed hacking campaign that compromised the servers of network management provider SolarWinds and, from there, the networks of 100 of its highest-profile customers, including nine US federal agencies. […] The latest reminder of the group’s proficiency comes from security firm Mandiant, which on Monday published research detailing Nobelium’s numerous feats—and a few mistakes—as it continued to breach the networks of some of its highest-value targets. Hackers infect random WordPress plugins to steal credit cards Date: 2021-12-08 Author: Bleeping Computer According to a new report by Sucuri, hackers performing credit card theft are first hacking into WordPress sites and injecting a backdoor into the website for persistence. These backdoors allow the hackers to retain access to the site, even if the administrator installs the latest security updates for WordPress and installed plugins. When the attackers use the backdoor in the future, it will scan for a list of administrator users and use their authorization cookie and current user login to access the site. AWS outage impacts Ring, Netflix, and Amazon deliveries Date: 2021-12-07 Author: Bleeping Computer Amazon AWS in the US-EAST-1 Region is suffering an outage that affected numerous online services, including Ring, Netflix, Amazon Prime Video, and Roku. The ongoing outage started at approximately 12 PM EST and is caused by problematic network equipment affecting the US-EAST-1 AWS region, which feeds a good portion of the connectivity for people in the northeastern part of the United States. FBI warning: Hackers targeting flaw in Zoho ManageEngine ServiceDesk Plus Date: 2021-12-03 Author: ZDNet The FBI and the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) are warning about the ‘active exploitation’ of a bug in Zoho ManageEngine ServiceDesk Plus before 11306. “Zoho ManageEngine ServiceDesk Plus before 11306, ServiceDesk Plus MSP before 10530, and SupportCenter Plus before 11014 are vulnerable to unauthenticated remote code execution.

The scams are run by global syndicates, and the money trail is murkier than ever. A mysterious threat actor is running hundreds of malicious Tor relays Date: 2021-12-03 Author: The Record Since at least 2017, a mysterious threat actor has run thousands of malicious servers in entry, middle, and exit positions of the Tor network in what a security researcher has described as an attempt to deanonymize Tor users. Tracked as KAX17, the threat actor ran at its peak more than 900 malicious servers part of the Tor network, which typically tends to hover around a daily total of up to 9,000-10,000. Some of these servers work as entry points (guards), others as middle relays, and others as exit points from the Tor network.

AUSCERT Week in Review for 3rd December 2021 Greetings, This Saturday marks three weeks until Christmas Day, a date that seems to be rapidly approaching! The festive season can often feel as though you’re being pulled in multiple directions. Some organisations slow down whilst others maintain and increase their activity as the year nears its end. Whatever the industry or however busy you may be, the following article provides Twelve Tips for Christmas Cybersecurity that apply to both our personal, and professional lives. There has been growing belief that nobody should have the ability to hide behind anonymous social media accounts, engaging in inappropriate commentary and conduct. As a result, the Australian government this week drafted anti-trolling legislation that will aim to clarify who is responsible for content published online. Requirements such as a mandatory complaints processes and a mandate for social media companies to provide names and contact details, are just some of the suggested laws that could be introduced as soon as early 2022. The scheduled rollout of mandatory two-factor authentication (2FA) by tech giant Google, will be activated automatically next Thursday, November 9. You can customize your 2FA, for either personal and business accounts with the options available on the Google Workspace Admin page that also contains additional information about the 2FA requirements, processes and support. Lastly, The University of Queensland and BLUE Inc. (Tokyo) are partnering to offer two half-day workshop seminars to address complex cyber security challenges, engage researchers, industry experts and students. Industry professionals from both countries will be presenting across four themes aimed at promoting and sharing game-changing interdisciplinary research between Australia and Japan. The workshops will be held in-person and online via Zoom on Wednesday 8 December and Wednesday 15 December. Click on your preferred date to learn more and register. Microsoft Exchange servers hacked to deploy BlackByte ransomware Date: 2021-12-01 Author: Bleeping Computer The BlackByte ransomware gang is now breaching corporate networks by exploiting Microsoft Exchange servers using the ProxyShell vulnerabilities.

Panasonic confirms cyberattack and data breach Date: 2021-11-30 Author: ZDNet Tech manufacturing giant Panasonic has confirmed that it’s network was accessed illegally this month during a cyberattack. In a statement released on Friday, the Japanese company said it was attacked on November 11 and determined that “some data on a file server had been accessed during the intrusion.” “After detecting the unauthorized access, the company immediately reported the incident to the relevant authorities and implemented security countermeasures, including steps to prevent external access to the network,” Panasonic said in a statement. “In addition to conducting its own investigation, Panasonic is currently working with a specialist third-party organization to investigate the leak and determine if the breach involved customers’ personal information and/or sensitive information related to social infrastructure.” CISA Releases Guidance on Securing Enterprise Mobile Devices Date: 2021-11-29 Author: SecurityWeek The United States Cybersecurity and Infrastructure Security Agency (CISA) last week published a Capacity Enhancement Guide to help organizations secure mobile devices and their access to enterprise resources. The Enterprise Mobility Management system checklist is meant to help businesses mitigate vulnerabilities and increase overall enterprise protections by implementing a series of best practices for securing enterprise-managed mobile devices. Microsoft Defender scares admins with Emotet false positives Date: 2021-11-30 Author: Bleeping Computer Microsoft Defender for Endpoint is currently blocking Office documents from being opened and some executables from launching due to a false positive tagging the files as potentially bundling an Emotet malware payload. Windows system admins are reporting that this is happening since updating Microsoft’s enterprise endpoint security platform (previously known as Microsoft Defender ATP) definitions to version 1.353.1874.0. When triggered, Defender for Endpoint will block the file from opening and throw an error mentioning suspicious activity linked to Win32/PowEmotet.SB or Win32/PowEmotet.SC. Hackers could steal encrypted data now and crack it with quantum computers later, warn analysts Date: 2021-12-01 Author: ZDNet Beijing-backed hackers might soon start trying to steal encrypted data — such as biometric info, the identities of covert spies, and weapons designs — with a view to decrypting it with a future quantum computer, according to analysts at US tech consultancy Booz Allen Hamilton (BAH). “In the 2020s, Chinese economic espionage will likely increasingly steal data that could be used to feed quantum simulations,” the analysts write in the report Chinese Threats in the Quantum Era. At risk are data protected by the current algorithms underpinning public-key cryptography, which some fear may be rendered useless for protecting data once quantum computers become powerful enough. Prediction Season: What’s in Store for Cybersecurity in 2022? Date: 2021-12-01 Author: Security Week The past year has been quite challenging and tiring for many IT and security professionals, as threat actors capitalized on the rapidly changing environment created by accelerated digitalization and cloud transformation in response to the COVID-19 pandemic. And while we all hope that the next year is better when it comes to the onslaught of daily phishing, ransomware, and credential stuffing attacks; cyber criminals will likely learn from this year’s successful tactics, retool, and pivot them into next year’s campaigns to wreak even more havoc in all lives. More than 300,000 Play Store users infected with Android banking trojans Date: 2021-11-29 Author: The Record More than 300,000 Android users were infected with banking trojans after installing apps from the official Google Play Store over the past few months, mobile security firm ThreatFabric said today. The malicious code was hidden inside fully functional apps that operated as QR code scanners, PDF scanners, security tools, fitness apps, and two-factor authenticators. But besides the legitimate functionality they offered, these apps also included a special module called a “loader.” In the cybersecurity field, loaders are small pieces of malware that are hidden inside an app. They typically contain very little and very benign functionality, such as the ability to connect to a remote server to download and run additional code. IKEA email systems hit by ongoing cyberattack Date: 2021-11-26 Author: Bleeping Computer IKEA is battling an ongoing cyberattack where threat actors are targeting employees in internal phishing attacks using stolen reply-chain emails. A reply-chain email attack is when threat actors steal legitimate corporate email and then reply to them with links to malicious documents that install malware on recipients’ devices. As the reply-chain emails are legitimate emails from a company and are commonly sent from compromised email accounts and internal servers, recipients will trust the email and be more likely to open the malicious documents.
