[ AGENT SECURITY ][ MACHINE CULTURE ]
The specific, especially dangerous combination of an agent having access to private data, exposure to untrusted external content, and the ability to communicate externally — any two alone are usually manageable, but all three together mean a single injected instruction can quietly exfiltrate real data.
REAL-WORLD EXAMPLE
"Before shipping, the team specifically checked whether the agent hit the lethal trifecta — turned out it did, on all three counts."
LORE & ORIGIN
Coined by security researchers in 2025 as a compact mental model for explaining why indirect prompt injection is so dangerous specifically in agents that combine these three capabilities.
