Analytic 1882

Real-time monitoring identifies an audit log clearing event or deletion/truncation of an Industrial Control System (ICS) vendor application log file, immediately preceded by other suspicious activity on the same host within a short lookback window. Documented in the CaddyWiper deployment alongside Industroyer2, explicitly intended to destroy evidence and slow forensic recovery. OT operational-fidelity gate: Alert only when execution violates an approved signer/hash/path/parent/process or tool allowlist, or originates from an unauthorized user/tool, and is tied to an OT asset or follow-on OT-relevant action. Suppress vendor-signed software, approved engineering utilities, diagnostics, patching, backup, and documented maintenance.
