Python Integration

Run LaZagne and Parse Results

import subprocess
import json
import os
from pathlib import Path

def run_lazagne(modules="all", output_dir="/tmp/lazagne"):
    """Run LaZagne and parse JSON output for credential audit."""
    os.makedirs(output_dir, exist_ok=True)
    cmd = ["python", "laZagne.py", modules, "-oJ", "-output", output_dir]

    result = subprocess.run(
        cmd, capture_output=True, text=True, timeout=120,
    )

    # Find the JSON output file
    json_files = list(Path(output_dir).glob("*.json"))
    if json_files:
        with open(json_files[0]) as f:
            return json.load(f)
    return []

Categorize Findings by Risk

HIGH_RISK_MODULES = {"lsa_secrets", "cachedump", "credman", "vault", "wifi"}
MEDIUM_RISK_MODULES = {"chrome", "firefox", "edge", "putty", "winscp", "filezilla"}

def categorize_credentials(lazagne_output):
    summary = {"high": [], "medium": [], "low": [], "total": 0}
    for module_result in lazagne_output:
        module_name = list(module_result.keys())[0]
        creds = module_result[module_name]
        if not creds:
            continue
        for cred in creds:
            entry = {"module": module_name, **cred}
            if module_name in HIGH_RISK_MODULES:
                summary["high"].append(entry)
            elif module_name in MEDIUM_RISK_MODULES:
                summary["medium"].append(entry)
            else:
                summary["low"].append(entry)
            summary["total"] += 1
    return summary
