Failure Pattern
Browser extensions operate with broad permissions but no cryptographic identity. Attackers compromise extensions to steal or manipulate data.
User Impact
The user blames the website — not the extension silently injecting or reading sensitive content.
Underlying Causes
Overprivileged extension APIs
No workload identity for extensions
Automatic updates introducing malicious code
Trust-Native Resolution
Each extension runs as an isolated trusted workload with its own TrustKey and is blocked unless identity is verified.
Broken Trust Assumption
Many of the most damaging breaches of the past decade occurred in environments that were fully authenticated, encrypted, and compliant.
Incidents including SolarWinds, NotPetya, Capital One, and MOVEit show a consistent pattern: attackers succeeded by inheriting trust, not by breaking it. Security controls validated access, but not intent.
