Greetings, Today, March 18th, is World Sleep Day – yes, really! There are many benefits from having quality sleep that includes improved mental health, mood, and decision-making. It has also been recognised as significant in preventative health and wellbeing, alongside fitness and nutrition. There are many ways that we can each improve our sleep that ranges from exercise in the morning to a warm shower at night and setting cut-off times from technology each evening to allow a wind down before sleep. The Sleep Health Foundation is on a mission to improve as many lives through better sleep and have a range of resources and activities designed to help them with that goal. Some folks that may be taking on some suggestions on improved sleep ahead of their presentations are our Speakers for this year’s AUSCERT2022 Cyber Security Conference! That’s right, we have officially announced our line-up that includes Keynote Speakers Kath Koschel of The Kindness Factory and Lesley Carhart amongst some familiar faces and first-timers. Visit the AUSCERT2022 website to see our speaking line-up and, perhaps register yourself to come along to the Gold Coast this May? Lastly, we wanted to advise, or remind those in the know, of the upcoming release of .au direct domain names. As detailed in our recent blog, the Australian Domain Administration (auDA) will be making the shorter and simpler domain names available from Thursday, March 24th, 2022. The blog highlights the advantages of the upcoming release but also outlines some precautionary measures that may apply to you and your business. QNAP warns severe Linux bug affects most of its NAS devices Date: 2022-03-14 Author: Bleeping Computer Taiwanese hardware vendor QNAP warns most of its Network Attached Storage (NAS) devices are impacted by a high severity Linux vulnerability dubbed ‘Dirty Pipe’ that allows attackers with local access to gain root privileges. The ‘Dirty Pipe’ security bug affects Linux Kernel 5.8 and later versions, even on Android devices. If successfully exploited, it allows non-privileged users to inject and overwrite data in read-only files, including SUID processes that run as root. Android malware Escobar steals your Google Authenticator MFA codes Date: 2022-03-12 Author: Bleeping Computer The Aberebot Android banking trojan has returned under the name ‘Escobar’ with new features, including stealing Google Authenticator multi-factor authentication codes. The new features in the latest Aberebot version also include taking control of the infected Android devices using VNC, recording audio, and taking photos, while also expanding the set of targeted apps for credential theft. New ransomware LokiLocker bundles destructive wiping component Date: 2022-03-17 Author: CSO Online A new ransomware operation dubbed LokiLocker has slowly been gaining traction since August among cybercriminals, researchers warn. The malicious program uses a relatively rare code obfuscation technique and includes a file wiper component that attackers could use against non-compliant victims. “LokiLocker is a relatively new ransomware family targeting English-speaking victims and Windows PCs. The threat was first seen in the wild in mid-August 2021,” researchers from BlackBerry’s Research & Intelligence Team said in a new report. New Linux botnet exploits Log4J, uses DNS tunneling for comms Date: 2022-03-15 Author: Bleeping Computer A recently discovered botnet under active development targets Linux systems, attempting to ensnare them into an army of bots ready to steal sensitive info, installing rootkits, creating reverse shells, and acting as web traffic proxies. The newly found malware, dubbed B1txor20 by researchers at Qihoo 360’s Network Security Research Lab (360 Netlab), focuses its attacks on Linux ARM, X64 CPU architecture devices. The botnet uses exploits targeting the Log4J vulnerability to infect new hosts, a very appealing attack vector seeing that dozens of vendors use the vulnerable Apache Log4j logging library. Ukraine invasion opens political rift between cybercriminals Date: 2022-03-15 Author: The Register Cybercriminals are taking sides over Russia’s deadly invasion of Ukraine, putting either the West or Moscow in their sights, according to Accenture. The consultancy giant’s Cyber Threat Intelligence team, which tracks illicit dark-web activity, said in a report dated Monday that this is the first time it has witnessed “financially motivated threat actors divided along ideological factions.” ESB-2022.1083 – macOS Monterey: CVSS (Max): 9.1* Apple has released advisory to address multiple vulnerabilities in the packages used in macOS ESB-2022.1076 – Apache HTTP Server: CVSS (Max): 7.4 Multiple vulnerabilities affecting Apache HTTP server have been fixed in version 2.4.53 ESB-2022.1108 – squid: CVSS (Max): 9.6 An incorrect input validation vulnerability leading to cache poisoning has been addressed ESB-2022.1147 – Bind 9.18.0: CVSS (Max): 7.0 ISC advises updates to Bind to address multiple vulnerabilities. ESB-2022.1165 – Treck TCP/IP Stack: CVSS (Max): 10.0 Treck TCP/IP Stack is widely used in embedded systems.

The AUSCERT team

From 24 March 2022, the Australian Domain Administration (auDA) will be introducing a new option for Australian internet users with the availability of .au direct domain names. The shorter and simpler domain names (such as pavlova.au, station.au and so on) will be open to individuals and organisations that wish to have an online presence, new or existing, with the proviso that they have a verified connection to Australia. Whilst offering convenience for businesses and individuals, it also presents an opportunity for cybercriminals to create malicious domains. At AUSCERT, it’s our purpose to understand just what those threats might be to provide our members with an analysis of the situation. While it is impossible to completely prevent all kinds of domain name abuse, the requirements auDA has in place (such as registrants needing to have an ‘Australian presence’) certainly help mitigate against widespread and easy abuse (as is prevalent in many other jurisdictions). auDA has extensive resources available should you wish to learn more, including detailed information regarding registering domain names in .au direct, timelines, domain conflict resolution and so on. In addition, you can contact your preferred domain retailer. However, in brief, some points of note are: auDA continues with its strict rules against .au domains being used in any malicious or illegal activities and will take action against recognised offenders. auDA will provide priority registration to those organisations with existing registered domains to the same name in ‘.au’. For example, here at AUSCERT, we have ‘auscert.org.au’ which gives us priority to register and use ‘auscert.au’. This priority period is for six months from the launch date (24 March 2022) to register the ‘.au’ domain after which, it becomes available to anyone. Essentially, this means you have until 20 September 2022 to register any existing domain names you wish to have the new ‘.au’ version of. An “Australian presence” will be required to register a .au direct domain and essentially requires one of: An ABN A Trademark number Australian identification document (passport, driver’s license, etc.) So, what does this mean for you? Be aware that the .au direct domains are being launched on 24 March 2022. Consider which of your existing domains you may wish to register in .au direct. We encourage all members wishing to undertake this process, to do so within six months to avoid any potential issues arising later. Determine whether there may be any potential conflicts with other domain name registrants and understand the auDA process for resolving the conflicts. Check the auDA website for complete details. Contact your preferred domain retailer to register your new domains. Consider which new (rather than existing) domain names you may wish to register. Be aware that the opening up of a new domain space always provides a potential for the resurgence of domain abuse (such as domain squatting, phishing, etc) and take pre-emptive measures such as domain registration in the new domain space. Please contact the team at AUSCERT if you have any security-related questions relating to the introduction of .au direct domains you believe we can assist with. All other questions concerning, for example, domain registration, conflict resolution and so on are best dealt with by reviewing auDA’s or your retailer’s .au direct resources.

As it enters the second week, the invasion of Ukraine continues to reveal risks, real and potential, for individuals and organisations the world over. Harvard Business Review discusses possible preventative measures to take in order to be as safe as possible and, what a global cyberwar may look like. New Linux bug gives root on all major distros, exploit released Date: 2022-03-07 Author: Bleeping Computer [Refer AUSCERT Security Bulletin: ASB-2022.0061] A new Linux vulnerability known as ‘Dirty Pipe’ allows local users to gain root privileges through publicly available exploits. Today, security researcher Max Kellermann responsibly disclosed the ‘Dirty Pipe’ vulnerability and stated that it affects Linux Kernel 5.8 and later versions, even on Android devices. The vulnerability is tracked as CVE-2022-0847 and allows a non-privileged user to inject and overwrite data in read-only files, including SUID processes that run as root. Malware now using NVIDIA’s stolen code signing certificates Date: 2022-03-05 Author: Bleeping Computer Threat actors are using stolen NVIDIA code signing certificates to sign malware to appear trustworthy and allow malicious drivers to be loaded in Windows. This week, NVIDIA confirmed that they suffered a cyberattack that allowed threat actors to steal employee credentials and proprietary data. The extortion group, known as Lapsus$, states that they stole 1TB of data during the attack and began leaking the data online after NVIDIA refused to negotiate with them. Big tech decries Australia’s anti-trolling Bill for not allowing innocent dissemination defence Date: 2022-03-07 Author: ZDNet Meta, Twitter, and YouTube have all echoed the same concerns about Australia’s proposed anti-trolling laws, saying it would place an “unprecedented level” of defamation risk on social media platforms as it seeks to remove the defence of innocent dissemination. The innocent dissemination defence allows entities, such as social media platforms, to not be liable for defamation if they had no knowledge of the defamatory material, and their failure to detect the material was not due to negligence. Russia-Ukraine war: NYC on ‘ultra-high alert’ amid increased risk of Russian retaliatory cyberattack Date: 2022-03-07 Author: Fox News New York state is facing “increased risk” of cyberattack from Russian retaliators, while city agents have seen more breach attempts amid heightened tensions that have arisen from the Russian invasion of Ukraine, officials said Monday. Sen. Kirsten Gillibrand, a New York Democrat, met with New York City and police department officials on Monday morning. The New York Police Department (NYPD) has found no specific credible cybersecurity threats to the city so far, but not for a lack of effort, officials have said. Samsung confirms hackers stole Galaxy devices source code Date: 2022-03-07 Author: Bleeping Computer Samsung Electronics confirmed on Monday that its network was breached and the hackers stole confidential information, including source code present in Galaxy smartphones. As first reported by BleepingComputer, the data extortion group Lapsus$ leaked at the end of last week close to 190GB of archives claiming to have been stolen from Samsung Electronics. Smartphone malware is on the rise, here’s what to watch out for Date: 2022-03-10 Author: ZDNet There’s been a surge in mobile malware attacks as cyber criminals ramp up their attempts to deliver malicious text messages and applications to users in order to steal sensitive information including passwords and bank details. Cybersecurity researchers at Proofpoint say they detected a 500% jump in attempted mobile malware attacks during the first few months of 2022, with significant peaks at the beginning and end of February. Internet Backbone Giant Lumen Shuns .RU Date: 2022-03-08 Author: Krebs on Security Lumen Technologies, an American company that operates one of the largest Internet backbones and carries a significant percentage of the world’s Internet traffic, said today it will stop routing traffic for organizations based in Russia. Lumen’s decision comes just days after a similar exit by backbone provider Cogent, and amid a news media crackdown in Russia that has already left millions of Russians in the dark about what is really going on with their president’s war in Ukraine.

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. Senate passes cybersecurity act forcing orgs to report cyberattacks, ransom payments Date: 2022-03-03 Author: ZDNet The US Senate approved new cybersecurity legislation that will force critical infrastructure organizations to report cyberattacks to the Cybersecurity and Infrastructure Security Agency (CISA) within 72 hours and ransomware payments within 24 hours. The Strengthening American Cybersecurity Act passed by unanimous consent on Tuesday after being introduced on February 8 by Senators Rob Portman and Gary Peters, ranking member and chairman of the Senate Homeland Security and Governmental Affairs Committee. Over 100,000 medical infusion pumps vulnerable to years old critical bug Date: 2022-03-02 Author: Bleeping Computer Data collected from more than 200,000 network-connected medical infusion pumps used to deliver medication and fluids to patients shows that 75% of them are running with known security issues that attackers could exploit. The findings reveal that tens of thousands of devices are vulnerable to six critical-severity flaws (9.8 out of 10) reported in 2019 and 2020. International hackers answer Ukraine’s call to launch cyber operations against Russia Date: 2022-03-02 Author: ABC As Russian artillery bombarded Ukraine’s infrastructure on Sunday, one of the country’s most senior government ministers issued an unusual call to arms. The world was already supplying Ukraine with anti-tank missiles and military intelligence, but Vice Prime Minister Mykhailo Fedorov, tweeting a link to a public channel on Telegram, also called for hackers and tech specialists to join the “cyber front”. Microsoft: Ukraine hit with new FoxBlade malware hours before invasion Date: 2022-02-28 Author: Bleeping Computer Microsoft said that Ukrainian networks were targeted with newly found malware several hours before Russia’s invasion of Ukraine on February 24th. Researchers with the Microsoft Threat Intelligence Center (MSTIC) observed destructive attacks targeting Ukraine and spotted a new malware strain they dubbed FoxBlade. DDoSers are using a potent new method to deliver attacks of unthinkable size | Ars Technica Date: 2022-03-02 Author: Ars Technica Last August, academic researchers discovered a potent new method for knocking sites offline: a fleet of misconfigured servers more than 100,000 strong that can amplify floods of junk data to once-unthinkable sizes. These attacks, in many cases, could result in an infinite routing loop that causes a self-perpetuating flood of traffic. Now, content-delivery network Akamai says attackers are exploiting the servers to target sites in the banking, travel, gaming, media, and web-hosting industries.

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. Employees’ dodgy tech habits posing a risk to Australian businesses Date: 2022-02-22 Author: Cyber Security Connect KnowBe4 announced new research which has found that more than six in 10 Australian office workers (63 per cent) don't believe using their work email for personal activity is a security risk to their employer. The KnowBe4 data also revealed that more than half of that number engage with suspicious emails and SMS and only 5 per cent can correctly identify which emails and SMS are legitimate or scams. Furthermore, only four in 10 (40 per cent) employees say they always report suspicious emails and SMS to the IT team responsible for cyber security. More than half (52 per cent) say they engage with suspicious emails and SMS. CISA publishes list of free security tools for business protection Date: 2022-02-18 Author: The Register The US Cybersecurity and Infrastructure Agency (CISA) has published a web catalog of free cybersecurity resources in the hope that those overseeing critical infrastructure can use the tools to better secure their systems.

Disturbing Mass Text Operation Terrorizes Ukraine as Russian Troops Move In Date: 2022-02-23 Author: The Daily Beast Ukrainian government websites were knocked offline Wednesday in a new wave of cyberattacks pummeling Ukraine, just as Russian forces are starting to roll into the country and Ukraine declares a nationwide state of emergency over Russia’s recent aggression. The sites of Ukraine’s Ministry of Foreign Affairs, its Security Service or SBU, and Cabinet of Ministers were all down Wednesday. Banks are also affected, Ukraine’s minister of digital transformation, Mykhailo Fedorov, said on his Telegram channel. Ukrainian soldiers have also recently reported receiving alarming text messages urging them to flee or be killed, in what appeared to be an attempt to degrade their morale. US says Russian state hackers lurked in defense contractor networks for months Date: 2022-02-17 Author: Ars Technica Hackers backed by the Russian government have breached the networks of multiple US defense contractors in a sustained campaign that has revealed sensitive information about US weapons-development communications infrastructure, the federal government said on Wednesday. The campaign began no later than January 2020 and has continued through this month, according to a joint advisory by the FBI, National Security Agency, and the Cybersecurity and Infrastructure Security Agency. The hackers have been targeting and successfully hacking cleared defense contractors, or CDCs, which support contracts for the US Department of Defense and intelligence community. Microsoft offers defense against 'ice phishing' crypto scammers Date: 2022-02-18 Author: The Register Microsoft has some advice on how to defend against "ice phishing" and other novel attacks that aim to empty cryptocurrency wallets, for those not already abstaining. Ice fishing involves cutting a hole in a frozen body of water in order to catch fish. Ice phishing, as Microsoft describes it, is a clickjacking, or a user interface redress attack, that "[tricks] a user into signing a transaction that delegates approval of the user’s tokens to the attacker." Australia promises cyber support to Ukraine as Russian forces array along its borders Date: 2022-02-21 Author: ABC News Australia will expand cyber training for Ukrainian officials and could join a broader coalition of Western countries to provide the besieged Eastern European nation with military equipment or other support as fears of a Russian invasion continue to mount.

Greetings, February 13 – 19 is “Random acts of kindness Week”, an opportunity for everyone to do one small act of kindness each day! You can help make kindness the norm! The foundation behind the initiative encourages and challenges everyone to try different activities from giving a gift card to being a kid again and letting someone know that they bring joy! Although celebrations end this weekend, every day of the year is an opportunity to be kind. To help you, the Random Acts of Kindness Foundation has some great ideas to inspire you to make kindness the norm. Someone that has made kindness part of their every day is Kath Koschel, our keynote speaker for AuSCERT2022. Kath’s amazing and inspiring story saw her choose to make kindness part of every day. The flow-on effects resulted in The Kindness Factory, whose mission it is to make the world a kinder place. The journey to where Kath is today was possible in large part, to her resilience. This aspect of who we are is discussed in our latest episode of “Share Today, Save Tomorrow”, AUSCERT’s podcast series. You will also hear from Kylie Watson, a Technology Executive and Sociologist, who talks about her experience and perspective of working in the cyber industry that incorporates psychology, providing a unique perspective. Lastly, AUSCERT recently finalised a range of training sessions that we will deliver in 2022, designed for anyone that looks after their organisation’s cyber security. You can view training dates and book directly online HERE. This training is exclusive for AUSCERT Members only. ‘You can’t stop it’: in rural Australia, digital coercive control can be inescapable Date: 2022-02-17 Author: The Conversation [This article contains information about domestic and family violence that may be triggering.] Domestic and family violence perpetrators commonly use technology such as phones and other devices as a weapon to control and entrap victims and survivors, alongside other forms of abuse. This “digital coercive control” is not bound to a particular location and can follow targets anywhere, any time they access devices or digital media. For women outside urban Australia, technology-enabled abuse can pose more risk than for those in cities. In research funded by the Australian Institute of Criminology, we spoke to 13 such women who have been subjected to digital coercive control to understand what it is like. Massive QR breach from NSW Government exposes 500,000 people Date: 2022-02-15 Author: news.com.au More than 500,000 addresses – including those of defence sites, domestic violence shelters and a missile maintenance unit – in a massive NSW Government QR code bungle. The hundreds of thousands of locations were collected by the NSW Customer Services Department through its QR code registration system, having registered as wanting to comply with Covid-Safe directions. Joint Aust-UK-US intelligence paper highlights ransomware threat Date: 2022-02-14 Author: InnovationAus A joint report coordinated by the cybersecurity authorities of the US, the UK, and Australia has warned of the increased global threat of ransomware attack and have advised organisations to take immediate precautions. In the financial year 2020-21 the Australian Cyber Security Centre (ACSC) received more than 67,500 reports of cybercrime an increase of 13 per cent on the preceding year. Released on February 9, the ACSC co-authored paper found that ransomware attackers increased their impact by targeting the cloud, managed service providers, industrial processes, the software supply chain, and by timing them on holidays and weekends. Emotet Now Spreading Through Malicious Excel Files Date: 2022-02-16 Author: Threatpost An ongoing malicious email campaign that includes macro-laden files and multiple layers of obfuscation has been active since late December. The infamous Emotet malware has switched tactics yet again, in an email campaign propagating through malicious Excel files, researchers have found.

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. Have a great weekend!

ASIO tracking foreign spies on dating apps Tinder and Bumble Date: 2022-02-09 Author: The Sydney Morning Herald The boss of Australia’s counter-espionage agency ASIO has warned foreign spies appear to be using dating apps such as Tinder, Bumble and Hinge to get sensitive information from Australians. In his latest annual threat assessment delivered on Wednesday night, Mr Burgess for the first time confirmed that espionage and foreign interference has supplanted terrorism as ASIO’s principal security concern. [Mr Burgess] also revealed his agency recently foiled a foreign interference plot in the lead-up to an election in Australia, which involved an attempt to install political candidates at the behest of a foreign government. Microsoft will block downloaded macros in Office versions going back to 2013 Date: 2022-02-08 Author: Ars Technica In the interest of combating ransomware and other malware, Microsoft is planning a major change in how its Office software handles macros: when files that use macros are downloaded from the Internet, those macros will now be disabled entirely by default. Current versions of the software offer an alert banner on these kinds of files that can be clicked through, but the new version of the banner offers no way to enable the macros. The change will be previewed starting in April in Office version 2203, before being rolled out to all users of the continuously updated Microsoft 365 version of Office starting in June. The change will also be enabled for all currently supported standalone versions of Office, including versions 2021, 2019, 2016, and 2013. The Mac, iOS, Android, and web versions of Office won’t be affected. China suspected of cyber attack on News Corp Date: 2022-02-07 Author: Cyber Security Connect According to Reuters, hackers broke into News Corp email accounts and compromised the data of an unspecified number of journalists, the media firm disclosed last week. The hack was likely aimed at gathering intelligence for Beijing’s benefit, according to News Corp’s internet security adviser. The breach was discovered in late January and affected emails and documents of what it described as a limited number of employees, including journalists. News Corp, which publishes The Wall Street Journal, confirmed that cyber security firm Mandiant had contained the breach. Australia’s anti-trolling Bill enters Parliament retaining defamation focus Date: 2022-02-10 Author: ZDNet The federal government has officially introduced the highly-publicised anti-trolling Bill into Parliament. The Bill, Social Media (Anti-Trolling) Bill 2022, was first announced by Australian Prime Minister Scott Morrison in November as a mechanism that would “unmask anonymous online trolls” and address toxic content existing on social media platforms. The anti-trolling Bill has since been touted by the Liberal Senator and Attorney-General Michaelia Cash as one of her party’s primary items that it wants to push out before the federal election. UK.gov threatens to make adults give credit card details for access to Facebook or TikTok Date: 2022-02-08 Author: The Register Adults will have to hand over credit card or passport details before they can access social media sites, the British government threatened this morning. Internet use age verification – first floated and then abandoned via the country’s 2017 Digital Economy Act – will return in the UK’s Online Safety Bill, digital minister Chris Philp MP has vowed, linking the technology, widely criticised by privacy activists, to protecting children from pornography websites. No early data on use of Australia’s cyber-abuse takedown laws Date: 2022-02-08 Author: iTnews Immmediate applications of Australia’s new cyber-abuse takedown laws that came into force on January 23 remain unclear, with parties on all sides saying it is too early to have access to meaningful data. The “world-first scheme” gives Australia’s eSafety commissioner Julie Inman Grant authority to have the ‘worst of the worst’ content removed from the internet, “no matter where it is hosted”.

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.

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.
