Windows kernel 0-day. Ring 0 rootkit. EDR visibility disruption. Post-quantum crypto. Lazarus. This attack chain is ridiculous. CVE-2026-68820 is an actively exploited use-after-free in Windows AFD.sys that Lazarus used to jump from a local foothold to SYSTEM and deploy FudModule v3.1 against defense and aerospace targets. And it gets better: • Windows kernel exploitation • FudModule rootkit • ML-KEM post-quantum key exchange • DLL sideloading • In-memory malware • Microsoft Graph + OneDrive C2 • Hijacked infrastructure • Security telemetry disruption Exploit devs and reverse engineers: study the kernel path. Malware analysts: study the implant chain. Red teamers: study the tradecraft. Blue teams + detection engineers: figure out what telemetry is still trustworthy after the attacker reaches Ring 0. Threat intel: this is Lazarus operationalizing serious Windows kernel research in the wild. Fresh technical deep dive: cyllex.io/blog/posts/lazarus… #0day #WindowsKernel #MalwareAnalysis #ThreatIntel
