Greetings, Earth Day is tomorrow! A great opportunity to be grateful for the world we live in and reflect on ways we as individuals can reduce our environmental footprint. Avoid single use items, reduce energy consumption, encourage recycling, conserve water, and plant a tree! Established in 1970 Earth Day has become a world phenomenon with over 190 countries participating in a wide variety of environmental activities to drive change. President of Earth Day, Kathleen Rogers, proclaimed this year’s theme is to invest in a green economy to pave a path for a healthy, prosperous and equitable future. So tomorrow make sure to take the time to do something to benefit our beautiful green world! Just as we must invest in protecting our natural environment so too must we protect our cyber environment too. With the increasingly growing rate of scams, it has become imperative for every organisation to invest in their cyber security by providing their employees with the latest education, training and resources to prepare for any attack. The ACCC reported a record loss of $3.1billion to scams last year an astonishing 80% increase over last year. Scammers and hackers have become far more sophisticated in the tactics they are utilising, making them appear genuine, believable, and very difficult to detect. Experts worry this will only continue to increase as artificial intelligence scams are on a rapid rise with hackers now using voice cloning technologies to trick people. Microsoft revealed a new AI system which could recreate a person's voice after listening to them speak for only 3 seconds, a spine tingling sign of how quickly technology could be used to convincingly replicate a key piece of someone’s identity. At this year’s AUSCERT2023 conference we are featuring a new tutorial delivered by global cyber security company, Palo Alto Networks. Their zero trust architects will be hosting a Security Posture Assessment workshop to provide an in-depth analysis of the current state of your security environment. The experts will consult your cyber teams on the vulnerabilities present and priority areas of your organisation, providing recommendations and objectives to strengthen against cyber attacks.Register today to invest in your cyber security protection, hurry spaces limited! … Google patches another actively exploited Chrome zero-day Date: 2023-04-19 Author: Bleeping Computer Google has released a security update for the Chrome web browser to fix the second zero-day vulnerability found to be exploited in attacks this year.

Greetings, As data breaches and cyber attacks are progressively becoming more prevalent, organisations and individuals are now under threat more than ever. As a result it is increasingly important to properly equip yourself with the correct tools and training to ensure you and your organisation are prepared for the growing possibility of an attack. The recent threat on 3CX is a cause for concern for most people – and for good reason! The Voice Over Internet Protocol (VoIP) software development company’s system caters to more than 12 million daily users and 600,000 companies worldwide, including some very high-profile organisations. Hackers reportedly compromised the app to target the company’s customers which could have exposed sensitive personal and financial data for all users and organisations involved. As these data threats and breaches are increasingly becoming more common, organisations and individuals must do all they can to avoid the negative repercussions that can result. It's important for individuals and organizations to take steps to protect themselves against cyber attacks, such as using strong authentication, keeping software up to date, avoiding suspicious links and emails, and backing up important data. Additionally, organisations should invest in their people, to empower them to be an active part of cyber security risk reduction. Resources like IDCare’s fact sheets are great information sources to educate yourself and colleagues on the appropriate measures to take against common threats. Scam watch can keep you updated with the latest threats and statistics. Also, something practical most people can do to help protect themselves and their loved ones is to employ Multi Factor Authentication (MFA), here’s some helpful information on how to enable it for a variety of services – https://2fa.directory/au/ Before we finish up for the week I would like to do a final reminder that Early Bird Offers and Member tokens are expiring today, March 31, for our 2023 AUSCERT conference. There’s never been a better time to further you and your organisation’s knowledge and expertise in cyber security, make sure to register today! Google finds more Android, iOS zero-days used to install spyware Date: 2023-03-29 Author: Bleeping Computer Google's Threat Analysis Group (TAG) discovered several exploit chains using Android, iOS, and Chrome zero-day and n-day vulnerabilities to install commercial spyware and malicious apps on targets' devices. The attackers targeted iOS and Android users with separate exploit chains as part of a first campaign spotted in November 2022. They used text messages pushing bit.ly shortened links to redirect the victims to legitimate shipment websites from Italy, Malaysia, and Kazakhstan after first sending them to pages triggering exploits abusing an iOS WebKit remote code execution zero-day (CVE-2022-42856) and a sandbox escape (CVE-2021-30900) bug. Crown Resorts confirms ransom demand after GoAnywhere breach Date: 2023-03-28 Author: Bleeping Computer Crown Resorts, Australia's largest gambling and entertainment company, has confirmed that it suffered a data breach after its GoAnywhere secure file-sharing server was breached using a zero-day vulnerability. The Blackstone-owned company has an annual revenue that surpasses $8 billion and operates complexes in Melbourne, Perth, Sydney, Macau, and London. This data breach was conducted by the Clop ransomware gang, which has shifted over the past year from encrypting files to performing data extortion attacks. In February, the threat actors claimed to have stolen data from 130 organizations over ten days utilizing a GoAnywhere zero-day vulnerability. This is the most detailed portrait yet of data breaches in Australia Date: 2023-03-28 Author: ABC News Every bubble in the chart [below] is a data breach that put Australians at likely risk of “serious harm”. It shows a total of 2,784 recorded breaches since the start of 2020 — covering everything from the Optus and Medibank breaches, which exposed the personal information of millions, to mistakenly sent emails only affecting a single unlucky person. The chart is based on the official record of data breaches reported to the Office of the Australian Information Commissioner (OAIC), obtained and published for the first time by the ABC. Hotel and property giant Meriton hit by data hack, personal documents may be at risk Date: 2023-03-29 Author: ABC News One of Australia's biggest property giants has been hit by cybercriminals who may have made off with highly sensitive personal data including birth certificates and bank details, as well as information about salaries and disciplinary proceedings. Guests and staff members employed by Meriton were affected by the data breach when hackers struck the luxury developer on January 14 this year. NGS Super says 'limited data' stolen in cyber attack – Security Date: 2023-03-28 Author: iTnews NGS Super, an industry superannuation fund serving the education and community sectors, said an attacker had stolen “limited data” from its systems. The fund said it detected and shut down an incident on March 17, but not before the attacker was able to exfiltrate some data. The stolen data was stored on “internal drives”, according to the fund; why it was stored there is a matter for investigation. “For our members we know that data was accessed, which for a group of members included their primary identifiers,” NGS Super said. Home Affairs to set up cyber and infrastructure security group Date: 2023-03-27 Author: iTnews Home Affairs will set up a new cyber and infrastructure security group from May that will lead industry partnerships and support the implementation of the next nation cyber security strategy.

Greetings, Some of the articles about AI language models wanting to escape and become human might be slightly alarming, but a real alarmist point of view may be whether AI will replace existing roles undertaken by humans. Already we’ve seen use cases emerge in the cyber security industry like using ChatGPT to create a dark web monitoring tool, however the previous article does point out that it’s important to realise the limitations of AI – such as its reliance on training data. Meanwhile entire new industries have sprung up in recent times, such as the field of data governance, and let’s not forget that cyber security itself is still a relatively young industry. Each of these industries and their sub-specialty areas require new training and fresh ideas. Perhaps it’s safer to “future-proof against AI” and upskill? At an event themed “Back to the Future”, it’s very likely AI will be discussed at length and there’s a plethora of included training during the first two days in the form of half and full day tutorials of the AUSCERT2023 Cyber Security Conference. However at least as far as we’re aware, unlike McFly you can’t travel back or forward in time, and there’s only one week left for early bird registrations. Member Tokens also expire then, so if you haven’t seen yours yet, ask your member representative. Another great way to learn and upskill is to follow cyber security podcasts like AUSCERT’s “Share Today, Save Tomorrow” – there’s a new one available now with some reflections on AUSCERT’s 30th birthday celebrations earlier this month. And now a selection of this week’s notable cyber security news articles, compiled by the AUSCERT Analyst Team: Ferrari Says Ransomware Attack Exposed Customer Data Date: 2023-03-20 Author: Security Week Italian sports car maker Ferrari said on Monday that a threat actor had demanded a ransom related to customer contact details that may have been exposed in a ransomware attack. “Upon receipt of the ransom demand, we immediately started an investigation in collaboration with a leading global third-party cybersecurity firm,” the iconic car maker said. “In addition, we informed the relevant authorities and are confident they will investigate to the full extent of the law.” Most consumers want data privacy and will act to defend it Date: 2023-03-22 Author: IAPP With new technologies, new types of data and new methods of collection defining of our current reality, privacy cannot merely be an afterthought. Language models are fueled by our personal data, artificial intelligence art generators sexualize without consent and the metaverse embodies “data collection on steroids.” In addition to these technological changes creating rifts in privacy, cracks have also appeared in the legal foundations protecting long-established privacy rights. New privacy risks, it seems, are everywhere. How to turn off Wi-Fi calling on Android to combat hackers Date: 2023-03-20 Author: Scripps News Google’s Project Zero team discovered multiple security flaws with Samsung Galaxy smartphones that could allow hackers to target devices easily. All a hacker would need is the victim’s phone number, which can be used to compromise the phone without the user knowing anything is wrong. “Tests conducted by Project Zero confirm that those four vulnerabilities allow an attacker to remotely compromise a phone at the baseband level with no user interaction and require only that the attacker know the victim’s phone number. With limited additional research and development, Hackers mostly targeted Microsoft, Google, Apple zero-days in 2022 Date: 2023-03-20 Author: Bleeping Computer Hackers continue to target zero-day vulnerabilities in malicious campaigns, with researchers reporting that 55 zero-days were actively exploited in 2022, most targeting Microsoft, Google, and Apple products. Most of these vulnerabilities (53 out of 55) enabled the attacker to either gain elevated privileges or perform remote code execution on vulnerable devices. Zero-day vulnerabilities are security weaknesses in software products that are publicly disclosed or exploited before a developer knows about it or releases a fix. Organizations Notified of Remotely Exploitable Vulnerabilities in Aveva HMI, SCADA Products Date: 2023-03-21 Author: Security Week Organizations that use human-machine interface (HMI) and supervisory control and data acquisition (SCADA) products from UK-based industrial software maker Aveva have been informed about the existence of several potentially serious vulnerabilities. Security advisories published last week by Aveva and the US Cybersecurity and Infrastructure Security Agency (CISA) inform users about three vulnerabilities in the InTouch Access Anywhere HMI and Plant SCADA Access Anywhere products. Software updates that patch all vulnerabilities are available from the vendor. Rio Tinto says staff’s personal data may have been hacked in memo after an attack on GoAnywhere software Date: 2023-03-23 Author: ABC News Personal data of Rio Tinto Ltd’s former and current employees may have been stolen by a cybercriminal group, according to a staff memo. Payroll information — such as pay slips and overpayment letters — belonging to a small number of employees from January 2023 had possibly been seized by the group, the memo showed. “Investigations now indicate a possibility that Rio Tinto data may be impacted,” it said. ESB-2023.1632 – thunderbird: CVSS (Max): 7.5 Debian reports that multiple security issues have been discovered in Thunderbird, which, if exploited could result in denial of service, the execution of arbitrary code or spoofing. ESB-2023.1693 – Rockwell Automation ThinManager: CVSS (Max): 9.8 An advisory issued by ICS-CERT reports of two vulnerbilities in Rockwell Automation ThinManager and encourages the end-users to implement the risk mitigations provided by the vendor. ESB-2023.1720.2 – Cisco DNA Center: CVSS (Max): 8.0 A vulnerability in Cisco DNA Center could could allow an authenticated, remote attacker to elevate privileges. Cisco has released software updates to address the vulnerability. ESB-2023.1710 – Jenkins Plugins: CVSS (Max): 8.8 Vulnerabilities in a number of Jenkins plugins have been reported. Jenkins project has released updates for some vulnerable products. ESB-2023.1727 – Cisco IOS XE Software for Cisco Catalyst 9300 Series: CVSS (Max): 6.1 Cisco has reported a high-rated vulnerability in its Catalyst 9300 series switches that could allow persistent code to be installed by an attacker at boot time.

Greetings, Before we get too caught up in St Patrick's Day celebrations today, we wanted to remind you that early bird registrations for the upcoming AUSCERT2023 Cyber Security Conference end in two weeks. Don't miss out on this opportunity to connect with industry experts and gain valuable knowledge and skills to enhance your organisation's security posture. Additionally, don’t forget that Member Tokens will also expire in two weeks, so be sure to use them before then. You can ask your member representative for help with that, and if you’re yet to write your business case to attend AUSCERT2023, check out last week’s blog for some convincing ideas to include. Not to throw too much of a downer on celebrations, remember any popular event like St Patrick’s Day can potentially be weaponised for use by scammers. The same goes for impactful news stories, such as this week’s unfortunate collapse of multiple financial institutions in the USA and Latitude’s cyber incident. I’m sure we can all imagine “viral St Patrick’s Day videos”, “we regret to inform you of a data breach”, “you have a toll trip on 17/03/2023, to avoid penalty notice please pay immediately” or similar hooks to entice victims to click malicious links. It could be argued that good cyber hygiene at home also helps improve cyber resilience in the workplace, because staff may employ the same practices whether they are handling their own personal data or the information assets of their employer. In your next internal cyber awareness campaign, why not include some personal cyber hygiene tips – there’s plenty of content available online. Over the years we’ve also seen some very inventive training modules created in-house by some of our members – if you’ve designed one, why not share your ideas with other professionals in the AUSCERT Slack Channel? And now a selection of this week’s notable cyber security news articles, compiled by the AUSCERT Analyst Team: Fortinet: New FortiOS bug used as zero-day to attack govt networks Date: 2023-03-13 Author: Bleeping Computer Unknown attackers used zero-day exploits to abuse a new FortiOS bug patched this month in attacks targeting government and large organizations that have led to OS and file corruption and data loss. Fortinet released security updates on March 7, 2023, to address this high-severity security vulnerability (CVE-2022-41328) that allowed threat actors to execute unauthorized code or commands. Microsoft fixes Outlook zero-day used by Russian hackers since April 2022 Date: 2023-03-14 Author: Bleeping Computer Microsoft has patched an Outlook zero-day vulnerability (CVE-2023-23397) exploited by a hacking group linked to Russia's military intelligence service GRU to target European organizations. The security vulnerability was exploited in attacks to target and breach the networks of fewer than 15 government, military, energy, and transportation organizations between mid-April and December 2022. Commonwealth Bank details transaction abuse detection method Date: 2023-03-16 Author: iTnews The Commonwealth Bank has provided more detail of the data points and language models it is using to detect financial abuse in transaction descriptions. The bank’s AI labs team has a research paper published on arXiv [pdf] that describes the “multi-step approach” and also invites input from “the wider research community” to improve on the current method. What happens if you 'cover up' a ransomware infection? For Blackbaud, a $3m charge Date: 2023-03-10 Author: The Register Blackbaud has agreed to pay $3 million to settle charges that it made misleading disclosures about a 2020 ransomware infection in which crooks stole more than a million files on around 13,000 of the cloud software slinger's customers. According to America's financial watchdog, the SEC, Blackbaud will cough up the cash – without admitting or denying the regulator's findings – and will cease and desist from committing any further violations. Why Healthcare Boards Lag Other Industries in Preparing for Cyberattacks Date: 2023-03-15 Author: Dark Reading As leaders responsible for prioritizing their organizations' goals, board members must push the cybersecurity agenda forward. Yet new research shows healthcare boards are far behind their peers in making cybersecurity a priority and understanding cyber-risks, despite the potentially severe consequences to patient safety and care. "Cybersecurity: The 2022 Board Perspective," a new global report from Proofpoint and Cybersecurity at MIT Sloan, found that cybersecurity is much lower on healthcare boards' agendas compared with other sectors. Although 77% of the 600 board members surveyed suggested cybersecurity is a top priority for their organizations, only 59% of healthcare directors concurred.

Greetings, This year AUSCERT is proud to announce that Rachel Tobac will be the keynote speaker at the AUSCERT2023 Conference. A well-known name in the cybersecurity industry as an expert in social engineering attacks, Rachel is also the CEO of SocialProof Security, the company she founded together with her husband. Rachel has a proven track record of hacking into Fortune 500 companies and is recognized as one of the top ethical hackers in the industry. Speaking of AUSCERT2023, some tutorials have limited capacity so if you haven’t already secured yours, jump onto the registration page now. We released details of the tutorials earlier this year to help you write those business cases for attendance at AUSCERT2023. And when you’re writing it don’t forget to mention that the tutorials are included at no extra cost, you’ll have the opportunity to learn about the latest cybersecurity threats and trends, and network with other cybersecurity professionals. Copy, paste, business case done! Although this is the 22nd annual conference, AUSCERT itself turned 30 this month. All of us are incredibly proud of that achievement, and we were honoured to celebrate together with many past AUSCERT team members and “friends of AUSCERT” this week at our birthday party in Brisbane. Many of those past team members literally built AUSCERT from nothing, during times when little else was available in the cyber security domain. Today, although our culture and values remain the same, we have shifted our focus where our members need it most: threat intelligence, incident support and cyber security education. Director of AUSCERT Dr David Stockdale, and AUSCERT’s Senior Manager Mike Holm spoke with IT News this week about AUSCERT’s proud heritage and our future direction. You can watch the video here. And now a selection of this week’s notable cyber security news articles, compiled by the AUSCERT Analyst Team: PoC exploit for recently patched Microsoft Word RCE is public (CVE-2023-21716) Date: 2023-03-06 Author: Help Net Security Patches for the flaw – which affects a wide variety of MS Office and SharePoint versions, Microsoft 365 Apps for Enterprise and other products – have been released by Microsoft last month. CVE-2023-21716 was discovered and privately disclosed by security researcher Joshua J. Drake in November 2022. It is a heap corruption vulnerability in Microsoft Word’s RTF parser that, if triggered, allows attackers to achieve remote code execution with the privileges of the victim. The flaw does not require prior authentication: attackers can simply send a booby-trapped RTF file to the victim(s) via email. Emotet malware attacks return after three-month break Date: 2023-03-07 Author: Bleeping Computer The Emotet malware operation is again spamming malicious emails as of Tuesday morning after a three-month break, rebuilding its network and infecting devices worldwide. Emotet is a notorious malware distributed through email containing malicious Microsoft Word and Excel document attachments. When users open these documents and macros are enabled, the Emotet DLL will be downloaded and loaded into memory. Fortinet warns of new critical unauthenticated RCE vulnerability Date: 2023-03-08 Author: Bleeping Computer Fortinet has disclosed a "Critical" vulnerability impacting FortiOS and FortiProxy, which allows an unauthenticated attacker to execute arbitrary code or perform denial of service (DoS) on the GUI of vulnerable devices using specially crafted requests. This buffer underflow vulnerability is tracked as CVE-2023-25610 and has a CVSS v3 score of 9.3, rating it critical. This type of flaw occurs when a program tries to read more data from a memory buffer than is available, resulting in accessing adjacent memory locations, leading to risky behavior or crashes. Akamai mitigates record-breaking 900Gbps DDoS attack in Asia Date: 2023-03-09 Author: Bleeping Computer Akamai reports having mitigated the largest DDoS (distributed denial of service) attack ever launched against a customer based in the Asia-Pacific region. DDoS is an attack that involves sending a large volume of garbage requests to a targeted server, depleting its capacity, and thus rendering the websites, applications, or other online services it hosts unreachable by legitimate users. Australian official demands Russia bring criminal hackers ‘to heel’ Date: 2023-03-09 Author: The Record A senior official in Australia criticized the Russian government on Wednesday for failing to properly police cybercriminals based in its jurisdiction. Michael Pezullo, a public servant rather than a politician — currently serving as the secretary of the Department of Home Affairs — said the Russian Federation hosted “the greatest density of cybercriminals, particularly those with ransomware,” in the world.

Greetings, It’s the first week of Autumn, symbolising harvest and abundance as well as the yellowing of leaves and, hopefully, cooler temperatures. Cooling things down might give cyber security practitioners a chance to catch up with the latest phishing trend – mimicking OpenAI’s ChatGPT payment pages, apps and downloads to commit a variety of crimes. As with any trend or current event, criminals will find a way to exploit other humans for their own gain. There’s been plenty of talk about using AI to recognise when other AI has created content, but a new concern arose this week when a software update caused Replika users to “lose” their digital companion. Some felt genuine grief over the loss of a loved one, although hopefully that’s an example of a learned behaviour pattern that can be overcome – just like imposter syndrome which affects many cyber security professionals. At this year’s AUSCERT2023 Cyber Security Conference, The University of Queensland’s Shelly Mills will lead a tutorial on that topic: “Tackling imposter syndrome: using psychology to disrupt (cognitive) malicious activity”. Speaking of AUSCERT2023’s tutorials, don’t forget to get in quickly with your selections, as some tutorials have limited capacity and registrations are on a ‘first come, first served’ basis. We have however reserved some spaces which we will fill from our waitlist by selecting people that identify as women, creating more opportunities for skills-improvement as part of the conference experience. For this year’s “Back to the Future” themed conference you’ll notice we’ve finalised the tutorial schedule early, so that attendees can choose from the wide range of topics during the registration process. Members of AUSCERT have already received their Member Tokens – ask your AUSCERT member representative for more information. Here’s selection of this week’s notable cyber security news articles, compiled by the AUSCERT Analyst Team: Attackers stole LastPass data by hacking an employee’s home computer Date: 2023-03-01 Author: The Verge LastPass says that a threat actor was able to steal corporate and customer data by hacking an employee’s personal computer and installing keylogger malware, which let them gain access to the company’s cloud storage. The update provides more information about how the series of hacks happened last year that resulted in the popular password manager’s source code and customer vault data being stolen by an unauthorized third party. Albanese government to appoint Coordinator for Cyber Security, amid increasing threat to systems and data Date: 2023-02-26 Author: The Conversation The federal government is further stepping up its efforts to improve Australia’s protection against increasing cyber threats, with Prime Minister Anthony Albanese on Monday [today] announcing the establishment of a Coordinator for Cyber Security. The aim is to “ensure a centrally coordinated approach” to the government’s cyber security responsibilities. This would include coordinating and “triaging” action after a major incident. Critical flaws in WordPress Houzez theme exploited to hijack websites Date: 2023-02-27 Author: Bleeping Computer Hackers are actively exploiting two critical-severity vulnerabilities in the Houzez theme and plugin for WordPress, two premium add-ons used primarily in real estate websites. The Houzez theme is a premium plugin that costs $69, offering easy listing management and a smooth customer experience. The vendor’s site claims it is serving over 35,000 customers in the real estate industry. The two vulnerabilities were discovered by Patchstack’s threat researcher Dave Jong and reported to the theme’s vendor, ‘ThemeForest,’ with one flaw fixed in version 2.6.4 (August 2022) and the other in version 2.7.2 (November 2022). CISA Issues Warning on Active Exploitation of ZK Java Web Framework Vulnerability Date: 2023-02-28 Author: The Hacker News The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a high-severity flaw affecting the ZK Framework to its Known Exploited Vulnerabilities (KEV) catalog based on evidence of active exploitation.

Greetings, We are very excited to announce that registrations are now open for the AUSCERT2023 Cyber Security Conference – Back to the Future! This year we are doing a couple of things differently with our tutorials. Firstly, we have worked hard to finalise the selection and scheduling of tutorials earlier than usual. This means that attendees can select their preferred tutorials at the time they complete their conference registration. Secondly, to leverage the advantages of diverse groups working and learning together we are creating and holding space to improve the gender diversity in our tutorials. Some tutorials are limited-capacity, and registrations for these are on a ‘first come, first served’ basis, with additional requests going into a waitlist. This year we’re reserving some spaces in these tutorials which we will fill from the waitlist by selecting people that identify as women, creating more opportunities for skills-improvement as part of the conference experience! News emerged this week that malicious actors are leveraging the popularity of ChatGPT to create fake web sites and social media pages used to distribute malware and steal credit card data. This is a good reminder that malicious actors are extremely good at recognising what people are interested in, concerned about or titillated by, and ruthlessly use this knowledge to achieve their objectives. Here is a selection of the rest of this week’s notable cyber security news articles, compiled by the AUSCERT analyst team: GoDaddy says a multi-year breach hijacked customer websites and accounts Date: 2023-02-18 Author: Ars Technica GoDaddy said on Friday that its network suffered a multi-year security compromise that allowed unknown attackers to steal company source code, customer and employee login credentials, and install malware that redirected customer websites to malicious sites. GoDaddy is one of the world’s largest domain registrars, with nearly 21 million customers and revenue in 2022 of almost $4 billion. In a filing Thursday with the Securities and Exchange Commission, the company said that three serious security events starting in 2020 and lasting through 2022 were carried out by the same intruder. Apple Updates Advisories as Security Firm Discloses New Class of Vulnerabilities Date: 2023-02-21 Author: Security Week The iOS 16.3 and macOS Ventura 13.2 advisories, originally released on January 23, have been updated to add three vulnerabilities. One of them is CVE-2023-23520, a race condition affecting the crash reporter component, which can allow an attacker to read arbitrary files as root. The other two security holes impact the ‘foundation’ component in Apple’s operating systems and they can allow an attacker to “execute arbitrary code out of its sandbox or with certain elevated privileges”, according to the tech giant. ChatGPT is bringing advancements and challenges for cybersecurity Date: 2023-02-21 Author: Help Net Security Understanding why ChatGPT is garnering so much attention takes a bit of background. Up until recently, AI models have been quite “dumb”: they could only respond to specific tasks when trained on a large dataset providing context on what to find. But, over the last five years, research breakthroughs have taken AI to a whole new level, enabling computers to better understand the meaning behind words and phrases. Medibank reveals attack vector and cost of 2022 security breach Date: 2023-02-23 Author: iTnews Medibank is going to take a $26 million half-year hit as the result of its 2022 security breach, and this is expected to climb to between $40 million and $45 million over the full year. The insurer has also gone public for the first time with technical detail of the attack. In a half-year results announcement [pdf], Medibank said the attacker first obtained the user ID and password used by a third-party IT services contractor.

Greetings, Today marks World Pizza Day, a celebration of one of the world's most beloved foods. Pizza has been around for over two thousand years, originating in Italy, and has since become a staple dish in households and restaurants all over the world. From classic Margherita to gourmet toppings, there's a pizza for everyone. As we celebrate the history of pizza, the AUSCERT team also took a moment to reflect on its own proud history. AUSCERT was founded in 1993, and next month will celebrate its thirtieth birthday. To mark the occasion, we released a blog entitled "AUSCERT: a proud history and bright future" which takes a deeper dive into AUSCERT’s history and outlines plans for the future. This blog truly is the essence of the whole AUSCERT team, summarising the combined efforts in producing our strategy for 2023. Late last year the team took a few moments away from analysing vulnerabilities, taking down phishing sites, delivering training and running a conference and instead attended two offsite workshops, one focused on “what is the culture of AUSCERT?”, and another on “what projects can we undertake to better serve our members?”. Combined with feedback from some of our members, our plans for 2023 are now underway. Next week we’ll share details of that, and don’t worry if you haven’t had a chance to give us feedback yourself – we’ve got plans to do that, too! Speaking of plans, very soon the AUSCERT2023 Cyber Security Conference registrations will be opened, so keep an eye on our announcements. Meanwhile here’s this week’s interesting news articles in case you missed them: New Wave of Ransomware Attacks Exploiting VMware Bug to Target ESXi Servers Date: 2023-02-04 Author: The Hacker News VMware ESXi hypervisors are the target of a new wave of attacks designed to deploy ransomware on compromised systems. "These attack campaigns appear to exploit CVE-2021-21974, for which a patch has been available since February 23, 2021," the Computer Emergency Response Team (CERT) of France said in an advisory on Friday. VMware, in its own alert released at the time, described the issue as an OpenSLP heap-overflow vulnerability that could lead to the execution of arbitrary code. MITRE Releases Tool to Design Cyber-Resilient Systems Date: 2023-02-03 Author: Dark Reading Cyberattacks are on the rise and enterprise defenders are protecting an increasingly expanding and complex attack surface. For many organizations, the focus is shifting away from prevention to resilience — to maintain essential business functions during an attack and recover quickly without losing too much downtime. Toward that end, MITRE has released the Cyber Resiliency Engineering Framework (CREF) Navigator, a free visualization tool for engineers designing cyber-resilient systems. OpenSSH Releases Patch for New Pre-Auth Double Free Vulnerability Date: 2023-02-06 Author: None The maintainers of OpenSSH have released OpenSSH 9.2 to address a number of security bugs, including a memory safety vulnerability in the OpenSSH server (sshd). Tracked as CVE-2023-25136, the shortcoming has been classified as a pre-authentication double free vulnerability that was introduced in version 9.1. "This is not believed to be exploitable, and it occurs in the unprivileged pre-auth process that is subject to chroot(2) and is further sandboxed on most major platforms," OpenSSH disclosed in its release notes on February 2, 2023. CISA releases recovery script for ESXiArgs ransomware victims Date: 2023-02-07 Author: Bleeping Computer The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has released a script to recover VMware ESXi servers encrypted by the recent widespread ESXiArgs ransomware attacks. Starting last Friday, exposed VMware ESXi servers were targeted in a widespread ESXiArgs ransomware attack. Since then, the attacks encrypted 2,800 servers according to a list of bitcoin addresses collected by CISA technical advisor Jack Cable. NIST Standardizes Ascon Cryptographic Algorithm for IoT and Other Lightweight Devices Date: 2023-02-08 Author: The Hacker News The U.S. National Institute of Standards and Technology (NIST) has announced that a family of authenticated encryption and hashing algorithms known as Ascon will be standardized for lightweight cryptography applications. "The chosen algorithms are designed to protect information created and transmitted by the Internet of Things (IoT), including its myriad tiny sensors and actuators," NIST said. "They are also designed for other miniature technologies such as implanted medical devices, stress detectors inside roads and bridges, and keyless entry fobs for vehicles." Put differently, the idea is to adopt security protections via lightweight cryptography in devices that have a "limited amount of electronic resources." ESB-2023.0705 – OpenSSL: CVSS (Max): 7.4 An updated version of libssl has been provided to address multiple vulnerabilities in OpenSSL ESB-2023.0745 – Google Chrome: CVSS (Max): None Google has released updated version of Chrome to address several vulnerabilities ESB-2023.0768 – Cortex XDR Agent: CVSS (Max): 5.5 A patch for a medium severity vulnerability has been provided by Palo Alto for Cortex XDR Agent on Windows Platform ESB-2023.0756 – tigervnc: CVSS (Max): 7.8 A privilege escalation vulnerability has been addressed in TigerVNC Stay safe, stay patched and have a good weekend!
