Analytic 2086

Real-time monitoring identifies direct PowerShell execution or indirect System.Management.Automation use with an unexpected parent, encoded/obfuscated arguments, unusual module loading, or execution followed by OT-relevant network/process activity. Alert only when the interpreter is not part of the asset's approved software/automation baseline or its execution context violates an approved signer/hash/path/parent/user rule, and require OT-relevant corroboration such as access to engineering files, ICS software/API use, communications with protected OT assets, configuration change, or another suspicious follow-on behavior. Suppress documented vendor software, engineering workflows, diagnostics, backup, patching, and approved maintenance.
