    Example session with this skill installed

    I exported Security and System logs from DC01 after a weird weekend. Was there a spray? Did anyone get in? Anything persistence-y?

    • Read your context and instructions
    • Compiled the windows event log

    Answer: yes — 2 CRITICAL, 6 HIGH.

    • CRITICAL: Successful RDP logon by Administrator from 203.0.113.77 after 15 failures (T1078)
    • CRITICAL: Security audit log cleared by Administrator (T1070.001)
    • HIGH: Password spray from 203.0.113.50 — 10 users / 30 min (T1110.003)
    • HIGH: Password guessing against Administrator (T1110.001)
    • HIGH: Account backupsvc created and added to Administrators (T1136.001 / T1098)
    • HIGH: Service WinUpdateHelper → C:\Users\Public\update.bat (T1543.003)
    • HIGH: PowerShell IEX (New-Object Net.WebClient).DownloadString(...) (T1059.001)

Detects password sprays (4625), interesting 4624 logon types, success-after-failures, account/group changes (4720/4732/…), audit log clears (1102), new services (7045/4697), suspicious PowerShell 4104, scheduled tasks (4698) and explicit credentials (4648). Every finding carries a MITRE ATT&CK ID.
