Last week, we partnered with the National Security Agency and other government agencies to publish research on Russia-aligned espionage actor #TA488’s abuse of a previously unknown #Zimbra mailserver vulnerability. 🚨 Today, we are following up with additional observations of the threat group’s exploitation of a cross-site scripting (XSS) vulnerability in Outlook Web Access (OWA). This blog shares this update: https://lnkd.in/edcHTh3C The activity shows: • That TA488 has greatly improved its operational security measures • Is writing more subtle and capable malware • Targets a wide range of sectors but still prioritizes collecting gov't/defense intel TA488 is doubling down on “half-click” exploits, now with an infection chain purpose-built for persistent access inside OWA. ⚠️ Organizations should review and audit their Exchange permissions and revoke tokens for affected add-ins. Additional guidance is in our blog.

A new blog from Proofpoint AI threat researchers highlights how cybercriminals are incorporating AI tooling and generated material into attack chains. 🔗 https://lnkd.in/esGx3uA4 We continue to observe activity on underground criminal forums, suggesting that Indirect Prompt Injection (IDPI) could be increasingly leveraged as an intrusion vector. Our blog explores several malicious IDPI methods that are being actively developed into tools and frameworks and advertised for sale. ⤵️ • IDPI via email • IDPI via PDF • IDPI via calendar invite (disguising the prompt as a meeting agenda) • IDPI via malvertising (embedding prompts in webpages) Security teams should be prepared to encounter these techniques in the near future. Which IDPI method most concerns you?
