Libraries Used

  • subprocess: Execute reg query /s to enumerate registry persistence keys
  • re: Pattern matching for suspicious values in registry entries
  • json: Baseline file I/O and structured output

CLI Interface

python agent.py scan [--categories run_keys winlogon ifeo] [--save-baseline out.json]
python agent.py compare --baseline baseline.json

Core Functions

scan_persistence_keys(categories=None)

Enumerates registry persistence keys across 8 categories and flags suspicious entries.

Parameters:

Name Type Description
categories list Optional subset of categories to scan (default: all 8)

Returns: dict with categories map, all_suspicious list, and total_suspicious count.

compare_baseline(baseline_file, current_scan=None)

Compares current registry state against a saved baseline to detect new persistence entries.

Parameters:

Name Type Description
baseline_file str Path to baseline JSON file from previous scan

Returns: dict with baseline_entries count, new_entries count, and findings list.
