AUSCERT Week in Review for 12th July 2024

Greetings, This week, we celebrate NAIDOC Week, recognising the history, culture, and achievements of Aboriginal and Torres Strait Islander Peoples. NAIDOC Week offers an opportunity for all Australians to learn about First Nations cultures and histories and participate in celebrations of the oldest continuous living cultures on earth. Visit the NAIDOC website for a full list of local events. This month's Patch Tuesday brought significant updates, addressing 142 security flaws across various Microsoft products. Among these, two vulnerabilities were actively exploited in the wild, posing immediate threats to users. Additionally, two zero-day vulnerabilities, which had been publicly disclosed but not yet exploited, were patched. These zero-days are particularly concerning as there may be an exploit available before a fix is released. The update also fixed five critical vulnerabilities, all classified as remote code execution (RCE) flaws. These updates highlight the importance of regular patch management to protect systems from known threats. Users and organisations are strongly advised to apply these patches promptly to mitigate the risk of exploitation. Keeping systems updated is a crucial step in maintaining a secure IT environment and defending against cyber threats. The National Anti-Scam Centre is urging Australians who have had money stolen by scammers to be wary of offers to recover their money for an upfront fee. Reports involving a money recovery element are on the rise. Between December 2023 and May 2024, Scam watch received 158 reports with total losses exceeding $2.9 million, including losses from the original scams. The number of reports increased by 129 percent compared to the previous six months, while financial losses decreased by 29 percent from $4.1 million. Australians aged 65 and older were the largest reporting group and suffered the highest average losses. Victims of previous scams are easily identified by criminals who commonly keep and sell information about individuals they have exploited. The best method to stay ahead of cyber threats is through training and education. With the necessary skills and expertise, you can ensure that you and your organisation are always protected from attacks. Check out our online training schedules to find out how you can enhance your knowledge. It’s also important for victims of scams to feel able to report and share their experiences without judgement, so please share information about scams with less knowledgeable friends and family.

AUSCERT Week in Review for 28th June 2024

Greetings, Events this week underscored the critical importance of staying updated on the latest cyber security threats and trends. Australia’s proactive approach to implementing security measures and educating the community plays a crucial role in mitigating risks and enhancing overall cyber resilience. The week began with an alert from the Australian Cyber Security Centre (ACSC) highlighting increased cyber threat activity targeting Snowflake customers. Businesses and critical infrastructure in Australia were advised to bolster their security measures and remain vigilant against potential attacks. Many organisations applied Microsoft's June 2024 Patch Tuesday updates, which addressed 51 vulnerabilities, including 18 critical remote code execution flaws. Addressing these vulnerabilities promptly helps organisations mitigate the risks associated with commonly used applications and systems. In other news, a Wednesday court filing provided some details about the September 2022 Optus data breach, from the perspective of Australia's Communications and Media Authority (ACMA). ACMA is leveraging its regulatory powers to pursue Optus, alleging that the company failed to adequately protect personally identifiable customer information, including failing to fix an identified coding error in all of its Internet-visible APIs and to continue to operate a vulnerable API for two years despite there being no need for its operation. The filing states that “The cyber attack was not highly sophisticated nor did it require advanced skills or proprietary knowledge of Optus's processes or systems. It was executed through a simple process of trial and error,”. ACMA is seeking civil penalties in the case. Singtel, the parent company of Optus, has advised investors that it cannot determine the quantum of penalties but will defend the case. This incident exemplifies how regulatory bodies are intensifying their efforts to hold organisations accountable for failing to adhere to appropriate practices in safeguarding personal information. Ensure your organisation is compliant with the necessary regulatory standards. If you need assistance in analysing your organisation's cyber security maturity level, contact our team at – grc@auscert.org.au. Cyber threats surge during Australia's EOFY tax season Date: 2024-06-25 Author: Security Brief As the end of the financial year (EOFY) approaches in Australia, organisations and individuals find themselves preoccupied with tax returns, financial statements, and compliance reports. This busy period also brings with it a heightened risk of cyber threats, creating a favourable environment for scammers and cybercriminals. Analysts have noted an uptick in seasonal cyber activities during the EOFY period, exploiting the chaos and urgency associated with tax-related activities. The most common threats include phishing scams, ransomware, business email compromise (BEC), and identity theft. If you're using Polyfill.io code on your site – like 100,000+ are – remove it immediately Date: 2024-06-25 Author: The Register [AUSCERT has identified the impacted members (where possible) and contacted them via email] The polyfill.io domain is being used to infect more than 100,000 websites with malware after a Chinese organization bought the domain earlier this year. Multiple security firms sounded the alarm on Tuesday, warning organizations whose websites use any JavaScript code from the pollyfill.io domain to immediately remove it. The site offered polyfills – useful bits of JavaScript code that add functionality to older browsers that is built into newer versions. These in-fills make life easier for developers in that by using polyfillers, they know their web code will work across a greater range of browsers. Progress quietly fixes MOVEit auth bypass flaws (CVE-2024-5805, CVE-2024-5806) Date: 2024-06-25 Author: Help Net Security [AUSCERT has identified the impacted members (where possible) and contacted them via email] Progress Software has patched one critical (CVE-2024-5805) and one high-risk (CVE-2024-5806) vulnerability in MOVEit, its widely used managed file transfer (MFT) software product. According to WatchTowr Labs researchers, the company has been privately instructing users to implement the hotfixes before they go public with the information. Hacker Claims Theft of 30M User Records From Australia Ticketing Company TEG Date: 2024-06-24 Author: Security Week A threat actor is boasting on a hacking forum the theft of information pertaining to millions of Ticketek users, roughly three weeks after the company acknowledged a data breach. On May 31, Ticketek Entertainment Group (TEG), an Australia-based live events and ticketing firm, announced that user account information had been compromised after hackers accessed a database stored on a cloud-based platform. “The available evidence at this time indicates that, from a privacy perspective, customer names, dates of birth and email addresses may have been impacted,” TEG said. Backdoor slipped into multiple WordPress plugins in ongoing supply-chain attack Date: 2024-06-25 Author: Ars Technica WordPress plugins running on as many as 36,000 websites have been backdoored in a supply-chain attack with unknown origins, security researchers said on Monday. ESB-2024.4118 – GitLab: CVSS (Max): 9.6* Gitlab has released critical patches for GitLab Community Edition (CE) and Enterprise Edition (EE). ESB-2024.4099 – SQLite: CVSS (Max): 9.8 SQLite could be made to crash or execute arbitrary code. ESB-2024.4076 – OpenVPN: CVSS (Max): 9.8 OpenVPN could allow unintended access to network services.

AUSCERT Week in Review for 21st June 2024

Greetings, We are thrilled to announce the release of another exciting episode of our podcast 'Share Today, Save Tomorrow'! In Episode 35: "Introducing Ivano", Anthony sits down with AUSCERT’s new General Manager, Ivano Bongiovanni, to discuss his career journey and future aspirations for AUSCERT. In the second half, Bek chats with Michael McAlary from AUSCERT about the recent makeover and improved user experience of the AUSCERT Member Portal, as well as future enhancements. Don't miss this insightful conversation! In other news, as a result of the ongoing legal action by the Australian Information Commissioner, more details have been released this week of the 2022 MediBank Private breach. It has been alleged that one of the causes behind the breach was the failure to implement multi-factor authentication (MFA) for authenticating remote access users. The MediBank story coincides with research released by Cisco Talos which links aspects of MFA to approximately half of the incidents investigated in the first quarter of 2024. Talos describes the underlying cause of 25% of incidents being users accepting attacker-originated push notifications, while 21% of incidents were caused by incorrect implementation of MFA solutions. Both of these news stories highlight the critical importance of integrating information security controls across the domains of people, processes, and technology. Security controls are only as effective as the people who design, implement and use them. Regular training and awareness programs ensure that employees understand the importance of security protocols, such as multi-factor authentication (MFA), and know how to respond to security threats. Explore our available training courses to enhance your knowledge of cybersecurity threats.

AUSCERT Week in Review for 14th June 2024

Greetings, This week, the Australian Signals Directorate (ASD) released an update to remind small and medium businesses to assess their cyber health. As we enter a period of heightened threats and attacks, it is crucial that every business is equipped with the appropriate resources and knowledge to ensure they are cyber resilient. For small and medium-sized businesses with limited resources, prioritising the most critical elements of cyber health is essential. Cyber attacks are occurring more frequently, and recovery can be costly, making every Australian business a potential target. In the 2022-23 financial year, the average cost of cybercrime for small businesses increased to $46,000, and for medium businesses, it rose to $97,000. Such costs could potentially destroy a business, driving it into liquidation. Australian small and medium businesses can take practical steps to enhance their cyber security by implementing the Essential Eight, which covers many of the critical elements of cyber health. AUSCERT offers members advice and consultations to help improve their cyber security readiness in alignment with their business objectives. We specialise in helping organisations confidently adhere to industry frameworks, standards, and benchmarks. Our maturity assessments are designed to identify and address cyber security gaps in your organisation. By taking proactive steps, you can enhance your cyber security posture and reduce information security risks. The recent Medibank case should serve as a wake-up call to Australian organisations to invest in their digital defences to meet the challenges of an evolving cyber landscape. All organisations have an ethical duty to protect the personal information they are entrusted with and many have regulatory and contractual obligations as well. The civil penalty proceedings filed by the Australian Information Commissioner against Medibank, in relation to its October 2022 data breach, exemplifies the regulatory body’s commitment to holding parties accountable. The Commissioner claims Medibank failed to take reasonable steps to protect personal information from 9.7 million Australians, in breach of the Privacy Act 1988. This failure led to the release of personal information on the dark web, exposing many Australians to severe negative ramifications.

Protecting Yourself: Safeguarding Against ATO and MyGov Phishing Scams

With the tax season just around the corner, AUSCERT is urging individuals to remain vigilant. This period is a prime time for cybercriminals to target unsuspecting individuals through phishing scams. These are typically circulated via various channels, including phishing emails, phone calls, text messages, and even fake websites. Malicious threat actors tend to increase their fraudulent activities utilising various phishing techniques to take advantage of the heightened financial activity during this period. AUSCERT has observed a significant increase in phishing scams impersonating MyGov and the Australian Taxation Office (ATO) during previous tax seasons. From July to October in 2022, AUSCERT received reports of around 1100 tax-related phishing emails and scams, a number that surged to approximately 2500 in 2023. These phishing emails typically impersonate official entities and may contain convincing logos and language to deceive recipients and urge users to click on a link, scan a QR code or download an attachment. The emails also claim that urgent action is required to avoid account suspension, try to trick users about a pending tax refund, highlight issues with a tax return or demand immediate action to avoid penalties. However, clicking on these links can potentially lead to malicious websites that steal Personally Identifiable Information (PII) or sensitive data like user credentials or credit card details. Additionally, clicking on the links may install malware on the user’s device, creating a backdoor for cybercriminals to monitor activities, track user behaviour, and steal login information. To protect yourself from ATO and MyGov related phishing scams during the upcoming tax season, it is crucial to take precautions like: Verify the source: Do not respond to unsolicited emails, text messages, or phone calls claiming to be from the ATO or MyGov. If it is an email, double-check the email address and sender information to confirm authenticity. Remember, the ATO or MyGov will never ask for sensitive information via email or SMS. Before providing any personal information, verify the legitimacy of the request by contacting the ATO or tax professionals through their official channels. Be wary of suspicious calls: If you receive a suspicious call from someone claiming to be from the ATO and demanding payment to receive a tax refund, it is advisable to end the call immediately. Keep in mind that the ATO will not threaten you with immediate arrest or use abusive language. Exercise caution with links and attachments: Avoid clicking on links or downloading attachments from unsolicited emails or text messages. Be cautious of urgent requests: Be wary of emails, text messages and phone calls pressuring you to act quickly or provide personal information. Take the time to verify the legitimacy of the communication. Protect personal information: Avoid sharing personal or financial details in response to emails, phone calls or text messages. Always be careful when providing information online. Report suspicious activity: If you receive a suspicious email claiming to be from the ATO or MyGov, report it to the appropriate authorities, such as the ATO’s scam reporting email address, the ACSC, or IDCARE. Keep software up to date: Ensure that your devices have the latest security updates and antivirus software to protect against malware and phishing attempts. By staying informed and vigilant, and following best practices for online security, individuals can reduce the risk of falling victim to ATO and MyGov related phishing scams during tax season. If you believe that your identity has been compromised or you have fallen a victim to a tax related scam, contact IDCARE on 1800 595 160.   Written by  Senior Information Security Analyst Vishaka

AUSCERT Week in Review for 7th June 2024

Greetings, With tax season close, AUSCERT is urging vigilance, as this is a prime time for cybercriminals to target unsuspecting people through phishing scams. These scams are typically circulated via various channels, including emails, phone calls, text messages, and fake websites. Malicious actors often increase their fraudulent activities during this period to take advantage of the heightened financial activity. AUSCERT has observed a significant increase in phishing scams impersonating MyGov and the Australian Taxation Office (ATO) during previous tax seasons. From July to October in 2022, AUSCERT received reports of around 1,100 tax-related phishing emails and scams, surging to approximately 2,500 in 2023. By staying informed and following best practices for online security, individuals can reduce the risk of falling victim to ATO and MyGov-related phishing scams. This week, concerning news emerged in the area of supply chain cyber security. Australian electronic prescription provider MediSecure has gone into administration. This follows a data breach reported in mid-May 2024, in which 6.5 terabytes of prescription data were stolen and leaked on a cybercrime forum. Last week, the Minister for Cyber Security, Clare O’Neil, publicly criticised MediSecure for the "unacceptably long time" it took to provide important information about the stolen customer data. Meanwhile, cloud storage and data analytics company Snowflake was the centre of a data breach impacting several high-profile customers, including Ticketmaster. Described by some in the media as "the world’s biggest data breach — in terms of impacted individuals," this incident underscores how supply chain risks can have far-reaching consequences. It also highlights the importance of understanding and utilising the security controls provided by service providers. Reports suggest that some of Snowflake’s customers were compromised due to single-factor authentication and use of stolen credentials. The best proactive approach to staying ahead of cyber threats is to ensure that you and all members of your organization are equipped with the most relevant knowledge.
