Failure Pattern
Tokens stored in the browser can be exploited (token replay) from any app or script that has memory access.
User Impact
User thinks: “I didn’t log in from that device,” while their browser session was silently harvested locally.
Underlying Causes
Tokens in memory rather than hardware-bound stores
No per-session cryptographic identity
Browser sandboxes not preventing extraction
Trust-Native Resolution
Sessions bind to device TrustKey + user identity, making replay impossible even if memory is stolen.
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.
