Greetings, Easter is one of Australia’s most popular times for a getaway—whether it’s a beachside escape, a cosy countryside retreat, or an overseas adventure. But while you’re planning a well-earned break, scammers are planning how to steal your holiday and money. As travel bookings surge over the Easter period, so too do reports of travel-related scams. Cyber criminals know many people are on the hunt for last-minute deals and accommodation—and they’re ready to take advantage. Here are some common travel scams to watch out for this holiday season. Fraudulent Listings & Accounts Scammers often create fake accounts and listings on trusted booking platforms like Airbnb and Booking.com, using stunning photos and prices that seem too good to be true. Some go further by hacking legitimate host accounts, changing payment details, or moving communication off-platform to make easier to steal money and harder to trace them. Phishing Scams Phishing is a common tactic where scammers send malicious emails or text messages that appear to be from legitimate sources. These messages often include fake booking confirmations, flight cancellations, or requests to "verify" your information. Travel prize scams are also on the rise—offering fake giveaways or competitions to lure victims in. Fake Passport Schemes A more targeted scam aimed at Australians involves emails impersonating the Australian Passport Office. The Department of Foreign Affairs and Trade (DFAT) warned last year that these emails may contain malicious links or QR codes designed to steal personal information. DFAT stresses it will never send unsolicited emails or texts asking you to click a link—though it may send one if you request a password reset or other action. Public Wi-Fi Risks Public Wi-Fi in airports, cafes, or hotels might be convenient—but it's often unsecured and can be malicious. Hackers can exploit these networks to steal sensitive data like passwords, credit card numbers, and travel documents. If you need to connect while travelling, use a VPN and avoid accessing personal or financial accounts over public networks. Concerns were raised this week about the future of the Common Vulnerabilities and Exposures (CVE) program due to a lack of certainty of the US government’s funding of the MITRE contract to deliver the service. A last minute reprieve was subsequently announced to extend funding for a further 11 months but doubts remains of the long term future of this critically important program.

Greetings Register now for our upcoming webinar examining the evolving role of cyber security in shaping organisational value propositions, led by AUSCERT general manager Ivano Bongiovanni. Taking place on Tuesday, 6 May, from 12:00pm to 1:00pm AEST, this dynamic panel discussion will feature leading industry experts sharing insights, challenges, and strategies connecting cyber security and business value. Panellists include Charles McDermid (BOQ), Rob Nobilo (Google), Lukasz Gogolkiewicz (Accent Group Ltd), and Dr Jodie Siganto (Privacy108). Don’t miss this opportunity to gain valuable perspectives from some of the most influential voices in the field—register today to secure your spot. The session will explore the evolution of Cyber Security-as-a-Service (CSaaS), with a spotlight on the rising influence of end-customers as a third market force. While still much smaller than the traditional B2B space, consumer demand is accelerating as individuals become more informed about cyber risks and increasingly value cyber security in their purchasing choices. This shift is evident in the widespread adoption of tools such as multi-factor authentication (MFA) and VPNs, as well as in marketing strategies that now frame cyber security as a core value-add. For providers such as MSSPs, this trend presents both opportunities and responsibilities—the need to remain ethical, innovative, and trusted is more important than ever. On the other side, demand-side organisations must navigate vendor complexity and ensure their cyber security investments align with overarching business objectives. Looking ahead, emerging B2B2C models—offering cyber security support not only to employees but also to their families—are opening new market opportunities while encouraging safer digital behaviours across work and home environments. As servitisation, trust, and adaptability continue to shape the future of CSaaS, this timely and thought-provoking discussion is one you won’t want to miss. Register now!

Greetings, The Australian Signals Directorate (ASD) has reported a rise in denial-of-service (DoS) attacks targeting critical online services such as banking, healthcare, and e-commerce. This increase is partly driven by insecure “Internet of Things” (IoT) devices, which cybercriminals exploit to overload websites with unsolicited and excessive packet traffic, resulting in subsequent outages. While organisations cannot fully prevent DoS attacks, they can mitigate the impact by following ASD’s Preparing for and Responding to Denial-of-Service Attacks guidance. Individuals can also play a role by securing their internet-connected devices using ASD resources like Internet of Things Devices and Secure Your Wi-Fi and Router. We are honoured to welcome Lieutenant General Michelle McGuinness as a keynote speaker for AUSCERT2025. Appointed as Australia’s National Cyber Security Coordinator in February 2024, LTGEN McGuinness leads national cyber policy, major incident response, and government-wide cyber preparedness. With 30 years of service in the Australian Defence Force, she has held key tactical, operational, and strategic roles, including Deputy Director Commonwealth Integration at the U.S. Defence Intelligence Agency.

Greetings, After last week’s whirlwind, it’s a relief to feel a sense of normality returning. However, for many still dealing with the aftermath of Cyclone Alfred, the road to recovery is far from over. Let’s stay mindful, support one another, and remain vigilant—especially as scammers continue to exploit those affected. With AI-generated scams on the rise, this week, we’re focusing on how to recognise them, spot key warning signs, and protect ourselves. Language can be a clear indicator of AI-generated content. Be on the lookout for overly formal phrasing, a lack of personal warmth, or awkward sentence structures. Similarly, when evaluating AI-generated visuals and audio, watch for unnatural movements, features that appear flawless yet artificial, and lighting inconsistencies. Backgrounds that look fabricated or hand gestures that seem stiff and unrealistic are additional warning signs. Voice cloning and scam calls are another growing threat. Watch out for any unusual pacing, voices that sound inhumanly fast or slow, or a lack of natural pauses. Speech that comes across as either too flat or overly dramatic, along with tonal or pronunciation inconsistencies, can also be red flags. To protect yourself from AI-driven scams, always stay cautious and verify unsolicited emails, calls, and messages. If an offer seems too good to be true or a request feels urgent, confirm it independently by reaching out to the person directly via a verified phone number or email. Never click on unknown links or respond without proper validation. Staying informed about the latest AI-driven scams is one of your strongest defences, as awareness helps you spot red flags before falling victim. Enabling Multi-Factor Authentication (MFA) adds an essential layer of security, making it significantly harder for scammers to access your accounts—even if they attempt to deceive you with AI-generated phishing tactics. Whenever possible, opt for phishing-resistant MFA for maximum protection. While generative AI has allowed cybercriminals to craft more convincing scams, their capabilities are often exaggerated. By staying informed, cautious, and proactive, you can recognise warning signs and stay ahead of evolving threats.
