Editorial Analysis
Living-off-the-land abuse of forgotten OS utilities undermines allowlist-based defences and shows that endpoint hardening must account for rarely-used legacy binaries.
Audit Windows endpoints for unnecessary legacy utilities like finger.exe and restrict their execution via application-control policies.
Attackers are weaponising decades-old built-in Windows tools to bypass modern defences, underscoring the need for endpoint hardening beyond patching.
