DET0766 Detection of Project File Infection
AN1898 Analytic 1898
Configured Windows object-access monitoring identifies a write to an Industrial Control System (ICS) engineering project file by a process that is not the recognized vendor engineering software, or by the vendor engineering software immediately after loading a project file from an untrusted source. Documented mechanism in Havex (trojanized vendor software/installers distributed via compromised vendor websites). 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. Collection requirement: use Windows Security Event ID 4663 with Object Access auditing and SACLs on approved project repositories; Sysmon FileCreate events can corroborate writes/overwrites but do not report generic file-open/read activity.
AN2116 Analytic 2116
Real-time monitoring identifies a write to Industrial Control System (ICS) project file paths on a Linux engineering station from a User Identifier (UID) not associated with the ICS engineering tool, or from the tool after loading a file from a removable media or network path not in the approved software distribution list. 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.
