The report analyzes legal theories (including Section 5 FTC claims and implied-contract arguments), the tension between confirmation and timely notice, critical-infrastructure expectations, proof-of-harm standards, and provides practical hardening controls and ThreatLocker-specific mitigations for defenders.
