Description

Your AI coding agent has access to your secrets, pulls in content from the outside world, and can run shell commands. According to Joe Holdcroft, that combination makes you one prompt injection away from a very bad time. The tools haven't changed the fundamentals of security — they've just made every existing risk move faster, and introduced a few genuinely new ones. What we cover:

• Why the "lethal trifecta" of agent capabilities creates a novel threat surface
• How text and markdown files have become a new class of vulnerability
• Slop squatting: the attack vector created by agents hallucinating package names
• The context supply chain — and why it mirrors the early days of npm security
• What a "CBOM" (context bill of materials) might look like and why we may need one
• How to think about agent trust using the contractor mental model
