ColdRecon assessment

Could a positive-security control have prevented this?

Verdict · no · opinion

The attack relied on social engineering via phone calls and MFA interception, not on unauthorized changes to a known-good state. A positive-security model would not prevent credential theft or real-time MFA relay.

Our assessments are opinion, grounded in the cited public facts. Read them critically.
