Techniques and Write-ups

• Do Smart People Ever Say They’re Smart? (SmarterTools SmarterMail Pre-Auth RCE CVE-2025-52691) - When @chudyPB and @SinSinology team up, shells are all but guaranteed. The timing of the patch vs the advisory (3 month gap) is interesting. With the rise of AI, will the patch-diff-to-exploit pipeline become commoditized? Will the AI powered EDR save us from the AI generated exploits?
• Pwning Claude Code in 8 Different Ways - Some "read only" commands were allowlisted by default, and of course they could be abused to execute arbitrary code.
• PatchGuard Peekaboo: Hiding Processes on Systems with PatchGuard in 2026 - This may be the most technical post I've read that also has clear AI generated parts like, "HVCI didn’t just raise the bar – it fundamentally changed the game by moving enforcement to a layer that kernel code simply cannot reach," and "the cat-and-mouse game isn’t dead – it’s just moved to a much smaller playing field." The "not x but y" pattern is appearing everywhere these days...
