What it detects

This rule flags process creation events where the executable matches Stracciatella.exe by filename, PE metadata (OriginalFileName/Description), or specific SHA256 hashes. Stracciatella is used to execute a PowerShell runspace from within C# (SharpPick technique), which can help attackers execute PowerShell while attempting to impair defenses. Detection relies on Windows process creation telemetry plus image path and PE metadata fields, or hash values, as provided by the environment.
