- Add validated mitre_attack frontmatter to all 754 skills (286 distinct techniques), verified against MITRE ATT&CK v19.1 via the official mitreattack-python library: 0 revoked, deprecated, or invalid IDs - Curate precise per-skill technique IDs for forensics, malware-analysis, threat-intel, and red-team skills (e.g. DCSync -> T1003.006, Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003) - Reconcile v19.1 tactic restructuring: Defense Evasion split into Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.* family and T1070.001/.002 remapped to active equivalents (T1685.*) - Normalize word-split tags across 35 skills (remove filename-derived stopword tags, add semantic cybersecurity tags) - Add api-reference.md for 3 skills that were missing it - Update README ATT&CK section with accurate v19.1 tactic distribution

# Hunting for Startup Folder Persistence
|
|
|
|
## Overview
|
|
|
|
Attackers use Windows startup folders for persistence (MITRE ATT&CK T1547.001 — Boot or Logon Autostart Execution: Registry Run Keys / Startup Folder). Files placed in `%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup` or `C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup` execute automatically at user logon. This skill scans startup directories for suspicious files, monitors for real-time changes using Python watchdog, and analyzes file metadata to detect persistence implants.
|
|
|
|
|
|
## When to Use
|
|
|
|
- When investigating security incidents that require hunting for startup folder persistence
|
|
- When building detection rules or threat hunting queries for this domain
|
|
- When SOC analysts need structured procedures for this analysis type
|
|
- When validating security monitoring coverage for related attack techniques
|
|
|
|
## Prerequisites
|
|
|
|
- Python 3.9+ with `watchdog`, `pefile` (optional for PE analysis)
|
|
- Access to Windows startup folders (user and all-users)
|
|
- Windows Event Logs for Event ID 4663 correlation (optional)
|
|
|
|
## Steps
|
|
|
|
1. Enumerate all files in user and system startup directories
|
|
2. Analyze file types, creation timestamps, and digital signatures
|
|
3. Flag suspicious file extensions (.bat, .vbs, .ps1, .lnk, .exe)
|
|
4. Check for recently created files (< 7 days) as potential implants
|
|
5. Monitor startup folders in real-time using watchdog FileSystemEventHandler
|
|
6. Correlate with known legitimate startup entries
|
|
7. Generate threat hunting report with T1547.001 MITRE mapping
|
|
|
|
## Expected Output
|
|
|
|
- JSON report listing all startup folder contents with risk scores, file metadata, and suspicious indicators
|
|
- Real-time monitoring alerts for new file creation in startup directories
