ColdRecon assessment

Could a positive-security control have prevented this?

Verdict · would prevent · opinion

A positive-security model that snapshots a known-good state and rejects unauthorized changes would likely have blocked the ransomware execution, as it would prevent the unauthorized RMM software from distributing malicious payloads.
