want to detect persistence via malicious scheduled tasks.Do not use this to alert on all task creation — administration creates tasks routinely. Hunt on the action (script hosts, encoded commands, temp paths) and trigger context.
schtasks/at.python scripts/analyst.py hunt events.csv
Flags tasks whose action runs powershell -enc, mshta, wscript/cscript, cmd /c, or
binaries from %TEMP%/%APPDATA%/Public, and schtasks /create command lines with the same.
Note logon/onstart triggers, very frequent intervals, and tasks hidden via Hidden flag or SD
manipulation.
Distinguish legitimate software tasks from intrusion by author, path, and action content.
Write a Sigma rule for task actions invoking script hosts or encoded commands.

Analyzes API call traces from a sandbox or API monitor (JSON) to group calls by category, reconstruct high-level behaviors (process injection, file drops, network, crypto), and flag suspicious call sequences. Activates for requests to analyze an API trace, interpret sandbox API logs, or identify behavior from Win32/Native API calls.

Analyzes Windows Authenticode signatures on PE files: checking for a signature, reading the signer certificate chain, detecting revoked/expired/stolen certs, and recognizing signature-stripping and catalog-signing abuse. Activates for requests to analyze a code signature, verify Authenticode, or assess signer trust on a PE.
