Greetings, One of the most important yet often overlooked aspects of cyber security is providing comprehensive training to all personnel. This training ensures employees understand their security responsibilities and how to mitigate risks effectively. For staff with specialized roles or elevated access to sensitive information, tailored privilege user training is crucial in addressing the unique risks they face beyond those of standard users. By equipping your team with the necessary knowledge and skills, you can foster a proactive and resilient cyber security culture within your organisation. Yesterday, the Australian Signals Directorate (ASD) released updated Personnel Security Guidelines, highlighting the importance of strong internal security practices. One of the most frequently reported cyber crimes in Australia is Business Email Compromise (BEC), which led to financial losses exceeding $98 million in 2021–2022. While 2024 statistics are still emerging, experts expect this trend to continue due to increasingly sophisticated cyber threat actors and reliance on digital communication. Training and education are vital in mitigating BEC risks. Educating staff on identifying warning signs and establishing clear authorisation processes can significantly reduce the chances of falling victim to such attacks. The ASD has outlined several guidelines to help organisations better manage these risks. For more targeted training, AUSCERT offers a range of courses tailored to various roles and skill levels. The Cyber Security Fundamentals course is designed to provide staff with essential, practical knowledge for staying safe online. Advanced courses are also available for technical teams, covering a wide array of specialized topics. Visit the AUSCERT website for more information on upcoming training courses!

Greetings, With school holidays upon us, many of us have little ones running wild and free – sometimes even on the internet! It's important to teach them about online safety, especially since holidays are a common time for criminals to launch phishing campaigns. Some of these scams target children by offering attractive games, promotions, or advertisements designed to entice them into clicking on malicious links or sharing personal information. To keep children safe online, take proactive steps to secure devices by keeping software up to date. Additionally, educate kids about the dangers of interacting with unknown links and the importance of protecting their personal information. Encourage them to speak up if they encounter anything suspicious or feel uncomfortable about an online interaction. By fostering open communication and awareness, we can help children navigate the internet safely and confidently, even during the busiest holiday seasons. AUSCERT's Sensitive Information Alerts (SIAs) are changing! From Wednesday 26th September, SIAs will no longer be emailed as an encrypted file. Instead, SIA emails will contain a unique URL to the AUSCERT Member Portal where you can generate a temporary link to download the file. This removes the need for encrypted files and will streamline the process! Please note that only an organisation's privileged users will initially have access to download SIAs. That person will be able to provide access to other users in the organisation by assigning the SIA role to them in the Settings/Users & Roles menu option. Privileged users will be able to check this setting a few days before the go-live date next week. To access any historical SIAs issued before the changeover, members will need to access the symmetric key from the Member Portal to decrypt the file. This will require encryption software such as PGP or GnuPG. Follow the link to the encryption keys page and match the thread ID with the received message. Import the decryption key into the encryption software, then select the encrypted file and decrypt it using the software's option.

Greetings, R U OK is encouraging everyone to ask "R U OK?" any day, because life happens every day. This reminder comes as 72% of Australians report experiencing elevated levels of distress. Each year, R U OK Day serves as a powerful reminder of the importance of checking in on others' well-being and actively listening to their concerns. Often, those facing challenges may not openly express their feelings, and a simple, empathetic conversation can make a huge difference. Asking "Are you okay?" and genuinely listening can offer emotional support and show someone they are not alone in their struggles. Meaningful connection and open dialogue about mental health help build a supportive and compassionate community. Prioritising mental health reduces stigma and creates an environment where people feel comfortable sharing their feelings and seeking help. It's a reminder that small acts of kindness and genuine concern can profoundly impact someone's life. For a range of free resources for your workplace, home or community, visit the R U OK? Day website. AUSCERT has always been a strong advocate for mental health support and services, actively implementing more mental health initiatives in the workplace and at our conferences. At AUSCERT2024, we again provided an onsite psychologist for attendees, offering the opportunity to discuss anything from mental wellbeing to life coaching. This year, we introduced mindfulness walks in the mornings that allowed delegates to start the day with a peaceful, serene stroll along the beach, and also introduced a dopamine hit of puppy pats and cuddles throughout the day – this was extremely popular! This week, Microsoft addressed and patched critical zero-day vulnerabilities as part of its monthly update. The first vulnerability, identified as CVE-2024-38217, affected Smart App Control and SmartScreen in Windows. This vulnerability allowed malicious files to bypass crucial security warnings and execute without raising any alarms. It appears to have been actively exploited by hackers for at least six years, with numerous samples detected on VirusTotal since 2018! The second vulnerability resided within the Windows Servicing Stack and allowed remote code execution (RCE). Identified as CVE-2024-43491, the cause of this vulnerability was a flaw in the Servicing Stack that essentially rolled back security fixes for optional components in Windows 10 version 1507. This left systems exposed to previously mitigated threats by removing prior security patches installed between March and August 2024. This is a timely reminder to always remain vigilant with patching systems regularly in your environment to mitigate and protect against such critical zero-day vulnerabilities. Please see this AUSCERT bulletin for more information on the above Microsoft vulnerabilities.

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.
