DET0795 Detection of Exploitation for Evasion
AN1927 Analytic 1927
Real-time monitoring identifies malformed or out-of-spec ICS protocol exchanges targeting an embedded device from a source outside the approved communication baseline. 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.
AN2154 Analytic 2154
Real-time monitoring identifies ptrace syscalls or /proc/pid/mem write operations targeting Industrial Control System (ICS) service processes from a process that is not a debugger or vendor diagnostic tool. 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.
AN2199 Analytic 2199
Real-time monitoring identifies Industrial Control System (ICS) network device syslog recording unexpected restarts or crashes coinciding with anomalous traffic patterns on management interfaces. 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.
AN2279 Analytic 2279
Real-time monitoring identifies an Industrial Control System (ICS) vendor process crashing unexpectedly, immediately preceded by an unusual cross-process memory access event from a process outside the recognized security/diagnostic tool allowlist. 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.

Exact source tags are not semantic relevance verdicts. Review actual rule conditions and observation points; imported rules are not backend-compiled or live-validated.
Pinned research references. No browser attack runner or production-validated detector is asserted. Imported procedures remain unvalidated; any bounded lab evidence has its own scope. ATT&CK / Atomic provenance · Detection provenance.
