ColdRecon assessment

Could a positive-security control have prevented this?

Verdict · unclear · opinion

OPINION: A positive-security model might have prevented execution of ransomware if it blocked unauthorized changes, but the text does not specify the initial access vector or whether the ransomware was deployed on endpoints, so it is unclear if it would have been effective.

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