**TL;DR:** Multiple high-risk, actively exploited incidents: a critical Cisco Secure FMC authentication-bypass (CVE-2026-20079) is being exploited in the wild; the BlueMoon exploit kit chains Chrome and Windows flaws and is used by at least four China-aligned APT clusters; infostealer malware (Lumma, Vidar) is harvesting replayable AI tokens that can bypass MFA, risking unauthorized access to AI platforms; additionally, AdaptHealth suffered a 4.1M-person data exposure and U.S. authorities disrupted the Xinbi scam marketplace—urgent actions recommended include patching FMC, rotating AI API keys, and enforcing hardware MFA.
