ir-playbook-suspicious-powershell skillA
ir-playbook-suspicious-powershell is agent-read markdown (skill) from gensecaihq/wazuh-autopilot: Incident-response playbook for malicious PowerShell — encoded commands, download cradles, Office-spawned scripts, in-memory execution, credential dumping, Defender tampering and registry persistence; use when Wazuh raises PowerShell or Sysmon detections (e.g. rules 92057, 91809, 92047, 92008, 91844, 92024) on Windows hosts..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# IR Playbook — Suspicious PowerShell Severity **medium → critical** depending on payload and follow-on activity. MITRE ATT&CK: T1059.001, T1027, T1140, T1105, T1566.001, T1003, T1547.001, T1112, T1562.001. Rule IDs are from the stock Wazuh 4.14 ruleset (levels official). Coverage depends on **Sysmon** (group `sysmon_eid1_detections` etc.) and **PowerShell/Operational script-block logging** (Event ID 4104; group `powershell`) being collected. Full procedure and decoding guidance: `references/playbook.md`. ## 1. Detection signals | Behaviour | Wazuh rules (level) | Source | |---|---|---| | Base64 / encoded command | rules 92057 (L12, PowerShell spawned PowerShell with base64 command), 91809 (L10, Base64 decoding in script), 92071 (L12, WMI-spawned PowerShell with base64) | Sysmon Event ID 1, script block | | Office / mshta launch chain (phishing) | rules 92047 (L12, Office started mshta), 92048 (L15, and ran script), 92050 (L12, Office → verclsid), 92156 (L12, Office loaded vbeui.dll), 92214 (L15, Office-created suspicious file) | Sysmon Event IDs 1 / 7 / 11 | …

mdr add gensecaihq/wazuh-autopilot/ir-playbook-suspicious-powershell@v2.1mdr add gensecaihq/wazuh-autopilot/ir-playbook-suspicious-powershell@sha256:f9f1c6d25613a4afPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
