Bondi shooting misinformation, ShinyHunters returns, and how to stay cyber safe while travelling

This week, for the last Cyber Uncut of 2025, David Hollingworth and Daniel Croft talk about Grok's spreading of misinformation regarding the tragic Bondi terror attack, OpenAI's admission of "high cyber risk", the re-emergence of ShinyHunters with a string of possible extortion attempts, ransomware attacks on medical centres, and important tips for using public Wi-Fi over the holidays. The pair kick things off with reports of how Grok utterly failed to deliver accurate information regarding the 14 December shootings targeting the Jewish community in Sydney. The chatbot utterly failed to meet the moment, leading to multiple instances of incorrect information circulating on X. In cyber security news, ShinyHunters is engaging in a string of extortion attempts that may – or may not be – linked to its breach of data analytics firm Mixpanel. It's a bit of a ride and a fascinating example of how quickly things can change in the cyber crime landscape. Plus, two more Aussie healthcare centres fall victim to ransomware attacks. And finally, some helpful travel advice, a wrap-up of our big moments from 2025, and some things to look forward to in 2026. See you next year The Cyber Uncut team
