RCE-class bugs in GitHub Copilot and Visual Studio (CVE-2026-21256, CVE-2026-21523). Both need user interaction; one needs local access. Chain with DWM or RDS EoP to SYSTEM, harvest creds, pivot. Dev workstations are treasure chests. If the path exists, you'll find domain. #RedTeam #OffSec

Between the chaos, overstimulation and just being down with the sickness, I tickled my brain with something fun on Monday.
Not much effort put into it but these are my #OffSec #AppSec & #AISec findings on the "agent" formally known as Clawdbot.
LOL what a mess and people are using this 😂😂😂.
