AUSCERT Bulletin Formats AUSCERT publishes two security bulletin formats: External Security Bulletin (ESB) – produced by vendors that are summarised and re-released by AUSCERT in a consistent format. AUSCERT Security Bulletin (ASB) – produced by AUSCERT with Overview, Impact and Mitigation information. ASBs typically describe critical vulnerabilities and emerging threats. They are collated from a variety of resources including vendors, security researchers and incident response teams around the world. Every AUSCERT bulletin contains a Bulletin Summary which highlights the essential information to assist in the vulnerability management process. The Bulletin Summary consists of the following categories (where relevant): Product Publisher Operating System Resolution CVE Names Original Bulletin URL Comment CVSS (Max) EPSS (Max) CISA KEV (if applicable) These categories are described in further detail below. ESB Structure Bulletin Titles and Email Subject Lines Bulletin titles and bulletin email subject lines display information in a concise format. The title includes the bulletin ID (eg ESB-2024.1234), revision number if applicable (eg ESB-2024.1234.2) and may include an ‘ALERT’ flag if the contents of the bulletin are time critical or reference a serious actively exploited vulnerability. The title also lists operating systems or hardware types that the vulnerability affects, and the product or product family. Example of a bulletin title: ESB-2024.1234 libarchive   Example of an email subject line: ESB-2024.1234 [SUSE] libarchive: CVSS (Max): 7.3 Bulletin Header The bulletin header consists of the ESB (or ASB) ID, a short summary of the purpose of the bulletin, and the date. Bulletin Summary The bulletin summary is an overview of the essential information in the bulletin typically used in the vulnerability management process. Both ESBs and ASBs contain a summary with individual fields as shown in this example: Product The product field displays the affected product name and version numbers (if any). Both ESBs and ASBs will have a Product field. Publisher Only present in an ESB, the Publisher field gives the name of the original source of the bulletin. This is often a vendor such as SUSE or Red Hat but it may also be another security team or research group. Operating System This field gives a list of operating systems or operating system families that are affected by the vulnerability. Resolution The Resolution field gives a quick indication on how to protect against the vulnerability. The values are: None: No resolution is currently available. Patch/Upgrade: A patch or new, unaffected version of the product is available. Note that only official vendor patches are acceptable as a patch – third party patches would be considered a mitigation. Mitigation: There are mitigation steps available that may be used, however there is no specific fix to the vulnerability. Alternate Program: Another program with similar functionality is available that is not vulnerable. CVE Names This field lists any CVE identifiers that relate to this vulnerability. CVEs are effective for tracking vulnerabilities that affect multiple products. Original Bulletin URL This field lists the URL of the original bulletin source. The original bulletin will often have additional links for further information. Comment This field contains any additional information that AUSCERT believes should be highlighted, including: CVSS (Max) EPSS (Max) CISA KEV (if applicable) These categories are described in detail further below. CVSS (Max) The Common Vulnerability Scoring System, or CVSS score, is included in all AUSCERT ASBs and ESBs in the Comment field. The CVSS is a published standard for assessing security vulnerabilities which classifies and scores vulnerabilities based on their severity. Scores are calculated based on a formula that depends on several metrics including required access, impact and authentication. The scores range from 0 to 10, with 10 being the most severe. This field consists of the CVSS (Max) CVSS Score, CVE-ID and CVSS description of the CVE with the highest score. If there is no CVSS (Max) score available at the time of publishing, the Comment field will show as “CVSS (Max): None”. For further information about how the CVSS (Max) is calculated and used, please see https://auscert.org.au/blogs/bulletin-impact-access-to-cvss-migration. EPSS (Max) Where an Exploitation Prediction Scoring System (EPSS Score) is available, this will also be included in the Comment field of a bulletin as “EPSS (Max)”. EPSS employs advanced algorithms to forecast the likelihood of vulnerabilities being exploited in real-world scenarios. A higher EPSS score will indicate a higher risk of exploitation which may provide input into the vulnerability management process. The syntax of the EPSS (Max) score is: EPSS (Max): (*Probability) (**Percentile) (CVE Number) (Date EPSS calculated). Probability: The likelihood of exploitation of the given CVE within the next 30 days Percentile: The vulnerability’s relative severity compared to others, ranking it within a distribution of similar security issues based on their assessed risks and potential impacts. AUSCERT advises members to research EPSS thoroughly before considering its application in vulnerability management. Understanding EPSS can require effort, and its suitability can vary depending on the environment.

The KEV catalogue is a CISA-maintained authoritative source of vulnerabilities that have been exploited in the wild. It is recommended that all members review and monitor the KEV catalogue and prioritize remediation efforts of the listed vulnerabilities to reduce the likelihood of compromise by known threat actors. The field consists of the CISA KEV CVE(s) and the CISA KEV url for reference. For example: For further information about CISA KEV, please see https://www.cisa.gov/known-exploited-vulnerabilities. Bulletin Updates and Versioning An ESB or ASB can be updated in the event of crucially new or updated information becoming available since the original date of publication. Updates will have a version number appended to the bulletin ID, eg ESB-2024.1234 will become ESB-2024.1234.2, and the ‘UPDATE’ tag will be added. ASB Structure An ASB contains the same bulletin title, bulletin header, bulletin summary and comment sections as an ESB, however the main body of an ASB differs from an ESB. The main body of an ASB generally consists of four headings: OVERVIEW: This is a summary of the vulnerability being reported and the products that are affected. IMPACT: This section outlines in more detail what the vulnerability allows attackers to perform (eg remote code execution), and the potential outcome of these vulnerabilities (eg significant data breaches, circumvent firewalls, intrusion detection systems, etc). MITIGATION: This section outlines steps to mitigate the risk. This can range from applying available patches to address the vulnerability to restricting or segmenting access to the network, including deploying additional monitoring and alerts against specific criteria. REFERENCES: This is a list of websites that report on the vulnerability. It can be a third-party website or the vendor itself. The websites are referenced within the ASB as the source of information being reported. Examples Full example of an ESB:     Full example of an ASB:    

CrowdStrike Technical Outage Exploited by Cyber Criminals – Stay Vigilant! On Friday 19 July, CrowdStrike released a sensor configuration update that triggered errors and system crashes in millions of Windows systems causing major business outages worldwide [2][3].  CrowdStrike has assured users that the outage was not due to a cyberattack [2]. Reports have since surfaced indicating that malicious actors are swiftly capitalising on the disruption created by this technical issue [1][4]. Reports from cybersecurity experts and industry analysts suggest that cyber criminals are leveraging the outage window to launch phishing campaigns and other malicious activities. These efforts aim to exploit emotions such as fear or urgency to manipulate users into making quick, uninformed decisions. This tactic aims to bypass users’ critical thinking and make fraudulent schemes more successful. Phishing attacks, in particular, have been observed mimicking CrowdStrike support communications. There also have been incidents where cyber criminals impersonated CrowdStrike staff in phone calls [1]. CrowdStrike has additionally noted instances where cyber criminals posed as independent researchers, falsely asserting evidence linking the technical issue to a cyberattack. They have offered supposed remediation insights and marketed scripts claiming to automate recovery from the content update problem [1]. In response to these developments, cybersecurity organisations and authorities have issued advisories urging heightened vigilance. Users are encouraged to verify the authenticity of communications, especially during service disruptions, and to adhere strictly to official channels for updates and support. CrowdStrike has shared a list of domains impersonating CrowdStrike’s brand during the outage. While some domains in this list are not currently hosting malicious content and may be intended to amplify negative sentiment, they could potentially support future social-engineering operations [1]. As CrowdStrike continues to restore full service functionality, the incident serves as a stark reminder of the evolving tactics used by cyber criminals. Organizations and individuals alike must remain vigilant, maintain updated security measures, and exercise caution in response to such incidents to mitigate potential risks effectively. The swift and coordinated response from cybersecurity communities highlights the importance of proactive measures in safeguarding against opportunistic cyber threats, ensuring resilience in the face of technical disruptions and potential exploitation by malicious actors.

Greetings, The winds picked up in the sunny state this week, bringing a noticeable drop in temperatures and allowing us to truly feel the winter chill. Perhaps we can also blame the winds for Queensland’s disappointing loss to New South Wales in the men's State of Origin. The Blues secured one of their greatest victories, defeating Queensland 14-4 at Suncorp Stadium, breaking a 19-year inability to win a decider there. Although it was a sad loss for the Maroons, we applaud the Blues for a good game and a great win. Until next time, Blues! This week, our analyst team distributed critical MSINS to affected members, alerting them to the Exim Flaw vulnerability, which is tracked as CVSS 9.1. Successful exploitation of this security defect could allow attackers to deliver executable attachments to inboxes, potentially leading to code execution and system compromise if the user opens the attachment. All organisations that had their Google Domains service migrated to Squarespace recently are advised to enable two-factor authentication on their Squarespace account, as it is not enabled by default. A number of cryptocurrency-related businesses appear to have been caught up in DNS hijacking attacks as a result of the way Squarespace migrated the service. Most of the noteworthy cases have been resolved; however, hundreds of domains are still alleged to be at risk of similar DNS hijacking, so it may not be over yet. It is crucial for organisations to adopt multi-factor authentication (MFA) to protect their data and maintain trust with customers and partners. By effectively implementing MFA, organisations can better defend against cyber threats and ensure the security of sensitive information. While MFA does not offer complete protection against all threats, it remains an essential component in reducing cyber security risks and safeguarding sensitive data. Atlassian Patches High-Severity Vulnerabilities in Bamboo, Confluence, Jira Date: 2024-07-17 Author: Security Week [Please also see AUSCERT bulletin: https://portal.auscert.org.au/bulletins/ESB-2024.4634/] Software vendor Atlassian on Tuesday released security-themed updates to fix several high-severity vulnerabilities in its Bamboo, Confluence and Jira products. The Australian firm called urgent attention to the Bamboo Data Center and Server updates that resolve two high-severity bugs, including one affecting the UriComponentsBuilder dependency that could allow an unauthenticated attacker to perform a server-side request forgery (SSRF) attack. Critical Exim Flaw Allows Attackers to Deliver Malicious Executables to Mailboxes Date: 2024-07-12 Author: Security Week [AUSCERT has identified the impacted members (where possible) and contacted them via email] A critical vulnerability in over 1.5 million internet-accessible Exim mail transfer agent (MTA) installations potentially allows attackers to deliver malicious executables to user mailboxes, Censys warns. The issue, tracked as CVE-2024-39929 (CVSS score of 9.1) and impacting RFC 2231 header parsing, results in filenames being incorrectly parsed, which could allow remote attackers to bypass the filename extension-blocking protection mechanisms.

Critical Apache HTTP Server Vulnerabilities Expose Millions of Websites Date: 2024-07-18 Author: Cyber Security News [Please also see AUSCERT bulletin: https://portal.auscert.org.au/bulletins/ESB-2024.4720/] The Apache Software Foundation has disclosed several critical vulnerabilities in the Apache HTTP Server, which could potentially expose millions of websites to cyber-attacks. These vulnerabilities, identified by their Common Vulnerabilities and Exposures (CVE) numbers, affect various versions of the Apache HTTP Server and could lead to severe consequences such as source code disclosure, server-side request forgery (SSRF), and denial of service (DoS). Infoseccers claim Squarespace migration linked to DNS hijackings at Web3 firms Date: 2024-07-15 Author: The Register Security researchers are claiming a spate of DNS hijackings at web3 businesses is linked to Squarespace's acquisition of Google Domains last year. The theory is that cybercriminals may have picked up on a flaw in the method Squarespace used to migrate Google Domains customer data over to its servers, allowing them to guess the email addresses associated with admin accounts and register the account for themselves. Hackers use PoC exploits in attacks 22 minutes after release Date: 2024-07-13 Author: Bleeping Computer Threat actors are quick to weaponize available proof-of-concept (PoC) exploits in actual attacks, sometimes as quickly as 22 minutes after exploits are made publicly available. That is according to Cloudflare's Application Security report for 2024, which covers activity between May 2023 and March 2024 and highlights emerging threat trends. Cloudflare, which currently processes an average of 57 million HTTP requests per second, continues to see heightened scanning activity for disclosed CVEs, followed by command injections and attempts to weaponize available PoCs.

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.

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.

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.

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. Contact us today for more information on how we can conduct a maturity assessment for your organisation and support you in meeting your business objectives.

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
