Greetings, This week, our team travelled to Adelaide to connect with our members! We had the opportunity for meaningful one-on-one conversations, gathered valuable feedback, and shared updates on our upcoming service developments. There is still time to register for the Digital Nation exclusive Brisbane event that is on Wednesday 4th of September, which delves deep into the evolving landscape of cyber security in Australia. Don't miss the opportunity to hear insights from our General Manager Ivano Bongiovanni! Click here to register. We released a new blog post on Tabletop Exercises (TTXs) this week! TTXs are an essential tool for testing an organisation's ability to respond effectively to security incidents. These exercises help identify gaps in incident response plans and prepare teams for real-world crises by guiding participants through realistic, discussion-based scenarios focused on roles, responsibilities, coordination, and decision-making. TTXs can be tailored to meet your organisation's specific needs, whether for incident response, business continuity, crisis management, or a mix of these areas. Participants from all roles—operational staff, cybersecurity professionals, communication teams, and executives—benefit from these exercises, enhancing cross-role coordination during incidents. Click here to read the full article! In case you missed it, this week we published an analysis of the Jenkins CLI path traversal vulnerability, CVE-2024-23897, exclusively for AUSCERT members. At the time of publication, just over 4% of Jenkins servers worldwide have been updated to mitigate this critical vulnerability. It's often useful to present a trusted third party's review when prioritising patching tasks, and we hope this analysis will assist those of you striving to patch your Jenkins instance. The Analyst Team has added Critical MSINs to AUSCERT's Early Warning SMS Alert Service, in addition to the existing critical vulnerability notifications. Whilst members' existing email notifications remain the same, the contacts nominated for Early Warning SMS Alerts will also now receive a corresponding SMS for Critical MSINs. The text message will always begin with the word "AUSCERT" and will direct the recipient to check for emails from AUSCERT for further information. Members can add additional Early Warning SMS Alert contacts in the Member Portal.

Greetings, We continuously strive to help our members minimize their exposure to cyber threats and understand that effective prioritisation in vulnerability management is a growing concern. To assist with these efforts, AUSCERT is pleased to introduce the Exploitation Prediction Scoring System (EPSS) within our bulletins and Critical MSINs, starting August 12, 2024. Read our blog article for more information!. This week, CrowdStrike published a root cause analysis of the recent widespread outage caused by a faulty update pushed out to its Falcon customers. The report details the chain of events and multiple independent testing failures that occurred during the creation and validation of the problematic configuration file distributed to customers. After such a widespread outage causing billions of dollars in damage across multiple countries, many are questioning who is legally responsible. Microsoft, whose ecosystem was impacted, estimated the outage affected 8.5 million Windows devices. Some organisations that were significantly affected by the incident have begun seeking legal recourse against CrowdStrike for compensation for the disruption to business. Delta Air Lines, which suffered widespread flight disruptions and service failures, is seeking financial damages against CrowdStrike. The outages cost Delta an estimated US$350 million to $500 million, as they are dealing with over 176,000 refund or reimbursement requests after almost 7,000 flights were cancelled. However, CrowdStrike has rejected allegations of gross negligence or misconduct, arguing that the terms and conditions of their contracts may limit their liability to customers, thereby severely restricting options for seeking redress under contract law. This has led some law firms to explore the possibility of pursuing class action under other claims, such as negligence. This case reveals the vulnerability of global supply chains and the significant impact IT disruptions can have on organisations worldwide. Major insurance companies are closely monitoring the situation, and many businesses are now scrutinizing their cyber insurance policies. This incident has prompted many to consider whether additional legal ramifications should be established to better protect consumers and hold responsible parties more accountable for their actions.

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.

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.
