Greetings, This week, our team participated in the annual APCERT Cyber Drill 2025 alongside 24 Computer Incident Response Teams (CIRTs) from 18 economies This year’s theme “When Ransomware Meets Generative AI” tested the response capabilities of leading Asia-Pacific teams, emphasising the growing risks from the malicious use of this rapidly evolving technology. The simulated scenario, involving AI-generated malicious code and exploited open-source vulnerabilities, challenged participants to review and strengthen their incident response procedures. The drill highlighted the need for proactive preparedness as Generative AI reshapes the cyber threat landscape. AUSCERT is proud to support APCERT’s vision of fostering a safe and reliable cyberspace across the Asia–Pacific through global collaboration and shared expertise. The ACSC, alongside the FBI, CISA and NCSC UK, has released a new advisory on Scattered Spider — one of 2025’s most active and dangerous cybercrime groups. Linked to major breaches, the group targets large enterprises using identity-based attacks and sophisticated social engineering, including phishing, vishing, MFA fatigue, and SIM swaps. Once in, they hide behind legitimate remote access tools (AnyDesk, TeamViewer, Teleport), steal credentials, and deploy DragonForce ransomware with the intention of executing large-scale data theft. The advisory urges organisations to act now: adopt phishing-resistant MFA (like hardware keys), drop SMS or push-only authentication, tighten helpdesk verification, and monitor or restrict remote access tools. Offline, tested backups, detailed logging, and updated detection using IOCs and MITRE ATT&CK are also critical. Scattered Spider’s tactics are evolving fast. Strengthening MFA, access controls, helpdesk security and maintaining public awareness and education is essential to staying ahead.

What if your passkey device is stolen? How to manage risk in our passwordless future Date: 2025-08-28 Author: ZDNET Part of the "passkeys are more secure than passwords" story is derived from the fact that passkeys are non-human-readable secrets — stored somewhere on your device — that even you have very limited access to. OK, so what happens to those passkeys if your device is stolen? ShinyHunters behind Salesforce data theft attacks at Qantas, Allianz Life, and LVMH Date: 2025-08-30 Author: Bleeping Computer A wave of data breaches impacting companies like Qantas, Allianz Life, LVMH, and Adidas has been linked to the ShinyHunters extortion group, which has been using voice phishing attacks to steal data from Salesforce CRM instances. In June, Google's Threat Intelligence Group (GTIG) warned that threat actors tracked as UNC6040 were targeting Salesforce customers in social engineering attacks. In these attacks, the threat actors impersonated IT support staff in phone calls to targeted employees, attempting to persuade them into visiting Salesforce's connected app setup page. On this page, they were told to enter a "connection code", which linked a malicious version of Salesforce's Data Loader OAuth app to the target's Salesforce environment.

Greetings, This week, Clive Palmer’s United Australia Party and affiliated group Trumpet of Patriots confirmed they were hit by a ransomware attack that exposed extensive personal data. The breach, discovered on June 23, compromised years of emails, identity documents, banking details, and employment history. While systems have now been secured and restored, the organisations were unable to notify all affected individuals directly. Authorities have been informed, and impacted individuals are urged to monitor their accounts, change passwords, and review past communications for any shared sensitive information. A new CyCognito study has identified the education sector as the most exposed to cyber risk across all industries, particularly in cloud infrastructure, APIs, and web applications. Vulnerability rates in education are significantly higher, 31% for cloud assets, 38% for APIs, and 35% for web apps—compared to the industry averages of 14%, 21%, and 20%, respectively. The increased risk is attributed to rapid digital transformation, reliance on legacy systems, underfunded cyber security, and small, overstretched IT teams. The fast shift to remote learning has also introduced numerous tools without adequate security controls, making educational institutions prime targets for ransomware, data breaches, and credential theft. AUSCERT, which counts many educational organisations among its members, is helping the sector mitigate these risks through timely threat intelligence, proactive alerts, expert incident response, and vulnerability notification services. By improving asset visibility and prioritising critical actions, AUSCERT supports long-term resilience in this high-risk environment.

Greetings, We’re excited to launch a brand new season of Share Today, Save Tomorrow with Episode 41 of the AUSCERT Podcast: “New Season + AUSCERT2025 Conference Wrap-Up.” In this episode, our very own Bek Cheb, Business Manager at AUSCERT, steps behind the mic to introduce the fresh new format and direction for the season ahead. Bek also shares key insights and standout moments from the AUSCERT2025 Conference held earlier this year. Whether you’re a returning listener or tuning in for the first time, this episode offers an engaging glimpse into what’s next for AUSCERT and the wider cyber security community. If you missed any presentations from AUSCERT2025 or want to revisit your favourites, don’t forget you can access the recordings now available on our YouTube Channel. From keynote speeches to technical deep dives, you can relive the most impactful moments of the conference at your convenience. Share these sessions with colleagues and peers because sharing knowledge is at the heart of strengthening our collective cyber resilience. This week, cyber criminals have launched a global scam involving over 17,000 fake news websites impersonating well-known media outlets such as CNN, BBC, and CNBC. These fraudulent sites publish fabricated articles featuring public figures ranging from world leaders to central bank governors falsely endorsing cryptocurrency investment schemes. Victims are lured via online ads to scam platforms like Eclipse Earn or Solara, which simulate legitimate trading environments but are designed solely to steal funds and personal information. These attacks are regionally-targeted (including Australia), using localised content, native language, and trusted local brands to gain credibility. Once a user engages, their data is often resold or used in future phishing campaigns. AUSCERT recommends verifying sources, avoiding unsolicited investment offers, and reporting any suspicious sites or ads to your internal security team or national cyber authority. Microsoft Patch Tuesday, July 2025 Edition Date: 2025-07-08 Author: Krebs on Security [AUSCERT has published security bulletins for these Microsoft updates] Microsoft released updates to fix at least 137 security vulnerabilities in its Windows operating systems and supported software. None of the weaknesses addressed this month are known to be actively exploited, but 14 of the flaws earned Microsoft’s most-dire “critical” rating, meaning they could be exploited to seize control over vulnerable Windows PCs with little or no help from users. New ServiceNow flaw lets attackers enumerate restricted data Date: 2025-07-09 Author: Bleeping Computer A new vulnerability in ServiceNow, dubbed Count(er) Strike, allows low-privileged users to extract sensitive data from tables to which they should not have access. ServiceNow is a cloud-based platform that enables organizations to manage digital workflows for their enterprise operations. It is widely adopted across various industries, including public sector organizations, healthcare, financial institutions, and large enterprises. Task scams: Why you should never pay to get paid Date: 2025-07-04 Author: We Live Security Many of us have been experiencing a cost-of-living crisis for years, and the news headlines remain filled with doom-laden predictions of what the future might hold. Against this backdrop, it’s understandable why many of us are looking for a side hustle or for even a new, better-paid job. But the scammers know this, and are ready to take advantage. In 2024 alone, employment scams reported to the FBI made fraudsters over $264 million. Many of these are so-called “task scams,” where victims are actually tricked into paying a “deposit” in order to get paid. It might sound unbelievable. But it’s easier to fall for than you think. Qantas says it has been contacted by a group claiming to have stolen data of its frequent flyers Date: 2025-07-08 Author: news.com.au Qantas says it has been contacted by a group claiming to be behind the theft of the data of millions of its frequent flyers last week. The airline said in a statement late on Monday that “a potential cybercriminal has made contact” but it would not disclose if a ransom was being sought. “As this is a criminal matter, we have engaged the Australian Federal Police and won’t be commenting any further on the detail of the contact,” a Qantas spokesman said.

Greetings, This week, Qantas experienced a major cyber attack compromising the personal data of up to six million customers. The breach, caused by a social engineering technique known as "vishing," exploited a third-party call centre system and exposed names, email addresses, phone numbers, birth dates, and frequent flyer numbers. Crucially, no passwords, PINs, credit card details, or passport information were accessed, and multi-factor authentication continues to protect frequent flyer accounts. Qantas is actively investigating the incident and will contact affected customers directly. Meanwhile, cyber security experts urge individuals to stay vigilant against phishing attempts, use strong and unique passwords, enable two-factor authentication, and monitor their accounts for unusual activity. Support lines have been set up to assist those impacted. This incident highlights the importance of securing supply chains. The UK’s National Cyber Security Centre (NCSC), offers a 12-principle framework to guide organisations through risk assessment, control, verification, and continuous improvement. The framework helps stakeholders set clear security requirements, embed them into contracts, and build long-term resilience. AUSCERT also offers a dedicated course on ‘Managing Third-Party Cyber Security Risk’, equipping participants with a deep understanding of third-party threats and the skills to identify, assess, and mitigate them. The course explores the business and data impacts of supplier vulnerabilities, outlines best-practice controls, and highlights the importance of ongoing monitoring and vendor assessments to ensure robust cyber security. Cisco scores a perfect 10 for a critical comms flaw Date: 2025-07-02 Author: The Register [See AUSCERT Bulletin https://portal.auscert.org.au/bulletins/ESB-2025.4373] If you're running the Engineering-Special (ES) builds of Cisco Unified Communications Manager or its Session Management Edition, you need to apply Cisco's urgent patch after someone at Switchzilla made a big mistake.

While it is unclear if this group is behind the Qantas attack, BleepingComputer has learned the incident shares similarities with other recent attacks by the threat actors. Microsoft security updates address CrowdStrike crash, kill ‘Blue Screen of Death’ Date: 2025-06-27 Author: CyberScoop Third-party antivirus software will no longer have access to the Windows kernel as Microsoft rolls out changes to reduce IT downtime from unexpected crashes or disruptions. When a faulty software update from cybersecurity firm CrowdStrike last year caused possibly the largest IT outage in history, Microsoft ended up taking much of the blame. Hacker Conversations: Rachel Tobac and the Art of Social Engineering Date: 2025-06-30 Author: Security Week Social engineering is the art of persuasion. Mostly, this is a good thing. Misused, it can have disastrous effects. Rachel Tobac is a cyber social engineer. She is skilled at persuading people to do what she wants, rather than what they know they ought to do. Does this make her a hacker? “Yes. I am a hacker. I hack people. I hack people over the phone, via email, by text message, across social media – and occasionally in person.” Social engineers hack people rather than computers. Initial Access Broker Self-Patches Zero Days as Turf Control Date: 2025-07-03 Author: Dark Reading A likely China-nexus threat actor has been exploiting unpatched Ivanti vulnerabilities to gain initial access to victim networks and then patching the systems to block others from breaking in to the same network.

Greetings, Cyber criminals are increasingly adopting and selling "uncensored" Large Language Models (LLMs) on dark web forums like BreachForums. Rather than building malicious AI tools from scratch, they are "jailbreaking" legitimate, powerful models from mainstream companies like xAI (the creator of Grok) and the French firm Mistral AI (creator of Mixtral). Many of these tools are being sold as WormGPT or variants with similar names and functionality, including FraudGPT and EvilGPT. On a potentially related note, research claims a 90% success rate in jailbreaking LLMs. AUSCERT is urging its members and the wider community to prepare for a surge in cyber incidents as the End of Financial Year (EOFY) approaches. Cybercriminals are once again exploiting this high-activity period—this time with more sophisticated tactics than ever before. AUSCERT has observed a sharp and consistent rise in phishing scams, particularly those impersonating trusted government and taxation agencies. The increased volume of payments, invoicing, and accounting activity during EOFY creates ideal conditions for threat actors to target already time-poor and pressured organisations. To help you stay prepared, AUSCERT has compiled key insights and practical guidance in our latest article. Read it here to learn how to better protect your organisation during this critical time. Citrix Releases Emergency Patches for Actively Exploited CVE-2025-6543 in NetScaler ADC Date: 2025-06-25 Author: The Hacker News [AUSCERT has published security bulletins for these updates: https://portal.auscert.org.au/bulletins/ESB-2025.4172] [AUSCERT has identified the impacted members (where possible) and contacted them via email] Citrix has released security updates to address a critical flaw affecting NetScaler ADC that it said has been exploited in the wild. The vulnerability, tracked as CVE-2025-6543, carries a CVSS score of 9.2 out of a maximum of 10.0. It has been described as a case of memory overflow that could result in unintended control flow and denial-of-service. However, successful exploitation requires the appliance to be configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server. Flaw in Notepad++ installer could grant attackers SYSTEM access (CVE-2025-49144) Date: 2025-06-25 Author: Help Net Security A high-severity vulnerability (CVE-2025-49144) in the Notepad++ installer could be exploited by unprivileged users to gain SYSTEM-level privileges through insecure executable search paths. There is currently no indication that the vulnerability is being leveraged by attackers, though technical details and a proof-of-concept (PoC) have been published – and redacted shortly after for security reasons. No, the 16 billion credentials leak is not a new data breach Date: 2025-06-19 Author: Bleeping Computer News broke today about "one of the largest data breaches in history," sparking wide media coverage filled with warnings and fear-mongering. However, it appears to just be a compilation of previously leaked credentials stolen by infostealers, exposed in data breaches, and via credential stuffing attacks. To be clear, this is not a new data breach, or a breach at all, and the websites involved were not recently compromised to steal these credentials. Instead, these stolen credentials were likely circulating for some time, if not for years. It was then collected by a cybersecurity firm, researchers, or threat actors and repackaged into a database that was exposed on the Internet. Reported Impersonation Scams Surge 148% as AI Takes Hold Date: 2025-06-24 Author: Infosecurity Magazine The volume of impersonation scams has soared 148% year-on-year (YoY) thanks in part to AI tools making life easier for cybercriminals, according to the Identity Theft Resource Center (ITRC). The US non-profit’s new 2025 Trends in Identity Report is based on analysis of identity crimes (compromise, theft and misuse) reported to it by victims from April 1 2024 to March 31 2025. Identity Is the New Perimeter: Why Proofing and Verification Are Business Imperatives Date: 2025-06-24 Author: Security Week Digital transformation has unlocked new opportunities – not just for innovation and growth, but also for cybercriminals seeking to exploit personal and sensitive information. According to the Future of Global Identity Verification report, more than two-thirds (69%) of organizations have experienced an increase in fraud attempts. Among companies with over 5,000 employees, the average annual direct cost of identity fraud is $13 million. That figure rises sharply with organizational size; for enterprises with more than 10,000 employees, 20% report annual direct and indirect identity fraud costs exceeding $50 million.

Organisations are actively engaging in meaningful conversations about the role of privacy and it’s clear that data protection is no longer just a regulatory obligation. It’s now recognised as a core business value and a collective responsibility. Creating a privacy-conscious digital environment requires genuine collaboration between industry, government, and individuals. By working together, we can build a future where data is protected, respected, and used responsibly. Here are a few key reminders: Collect Only What’s Necessary – Limit data collection to what’s essential to reduce risk and strengthen compliance. Embed Privacy in Culture – Treat privacy as a core organisational value, not just a regulatory requirement. Everyone Has a Role – From daily habits to major decisions, individual actions directly influence privacy and security. Privacy Awareness Week is more than a one-week focus – it’s a long-term commitment. By embedding privacy into our culture, practices, and mindset, we not only meet today’s standards but also lay the foundation for a safer digital future.

Greetings, Next week is Privacy Awareness Week, running from 16 to 22 June. This annual initiative encourages individuals, organisations and government agencies to take privacy seriously and raise awareness about the importance of protecting personal information. The 2025 theme is “Privacy: It’s Everyone’s Business”, and we’re being asked to shout it from the rooftops! Led by the Office of the Australian Information Commissioner (OAIC), Privacy Awareness Week is supported by state and territory privacy regulators as well as members of the Asia Pacific Privacy Authorities forum. Privacy is protected both in Australia and internationally through a range of laws. The OAIC primarily administers the Privacy Act 1988, which is the key piece of federal legislation governing the handling of personal information. In addition, each Australian state and territory has its own privacy laws that apply to their public sector agencies. A recent Help Net Security article highlights the growing threat of Vendor Email Compromise (VEC) attacks, which have led to over $300 million in attempted thefts within a year. VEC attacks involve cyber criminals impersonating trusted vendors to trick employees into actions like transferring funds or disclosing sensitive information. The report found that 72% of employees in large organisations (50,000+ staff) who read a VEC email went on to engage with it, with entry-level sales staff being particularly vulnerable. Industries like telecommunications and energy/utilities saw the highest engagement rates, and prior victims were more likely to be targeted again. The report also revealed that VEC attacks are significantly underreported—only 1.46% of advanced text-based email threats were flagged to security teams, leaving organisations unaware of many potential breaches. In regions like Europe, the Middle East and Africa, engagement with VEC was 90% higher than with BEC (Business Email Compromise) attacks, yet detection and response lag behind.

Greetings, The Australian Government has enacted new legislation requiring certain organisations to report ransomware and cyber extortion payments within 72 hours. Effective from 30 May 2025, the law applies to businesses with an annual turnover of at least AUD $3 million, as well as all entities within the critical infrastructure sector. If an organisation is a reporting entity, as defined under Part 3 of the Cyber Security Act 2024, they must submit a report via the Australian Signals Directorate (ASD) at cyber.gov.au/report within 72 hours of making a ransomware or cyber extortion payment or becoming aware that a payment has been made on their behalf. The regulation covers both monetary and non-monetary payments made in response to ransomware or extortion demands, whether paid directly or via a third party. Reports must include key details such as the nature of the incident, the attacker’s demands, contact information, communications, the payment amount and any other relevant information. The Department of Home Affairs will work with organisations to support the reporting process, identify challenges, and ensure smooth implementation. While the ASD will not enforce compliance within the first six months, it will support entities in responding to, mitigating, and recovering from cyber incidents. This legislation aims to increase transparency and strengthen Australia’s cyber resilience by improving visibility of ransomware activity and informing future protective measures.
