On this week’s show, Patrick Gray and James Wilson are joined by special guest The Grugq. They discuss the week’s cybersecurity news, including:

  • Vercel got owned, and there’s a few infostealer and compromised employee dots to connect
  • Mozilla used Mythos to find 271 bugs, which feels like a sign of the bug-pocalypse
  • Speaking of the bug-pocalypse, is that why NIST is noping out of enriching a bunch of bugs?
  • The NSA is using Mythos even though the government did that whole Anthropic blacklisting thing
  • And DDos attacks hit a couple of smaller-player socials

This week’s episode is sponsored by Permiso. Ian Ahl chats to Pat about the subtle signals Permiso uses to detect ShinyHunters-style activity in cloud and on-prem environments.
