FINDINGS ░▒▓

warningPython subprocess / os.system usageos.system() or subprocess with shell=True / suspicious commands can execute arbitrary shell commands. Plain pip/package installs are usually benign.build-tester/scripts/wsl.py

    try:
        result = subprocess.run(
            ["wsl", "bash", "-lc", "ip route show default"],
            capture_output=True, text=True, timeout=5,

        sys.stdout.flush()
    retval = os.system(cmd)
    if retval != 0 and exit_on_fail:
        print(f"fatal error: command '{cmd}' failed")

    can_apply = not bool(
        os.system(f'patch -p1 --dry-run --force -i "{patch_file}" > /dev/null 2>&1')
    )
    can_reverse = not bool(

criticalGo os/exec usageos/exec is used to run external commands. In malware it drops payloads, modifies the system, or opens shells.legacy/launcher/exec.go

	// Print args
	cmd := exec.Command(execName, args...)

	setProcessGroupID(cmd)

infoSuspicious files are not reachable from entry pointsFlagged files exist but are not imported by any entry point. They may be dead code, tests, or attack payloads triggered by another mechanism.+2

infoBase64 encoding usedatob() or Buffer.from with base64. Common in legitimate code but also used to hide malicious URLs.additions/juggler/content/Runtime.js

      if ('ta' in value) {
        const binary = atob(value.ta.b);
        const bytes = new Uint8Array(binary.length);
        for (let i = 0; i < binary.length; i++)

Scores are heuristics. A “safe” verdict means no known-malicious patterns were found — clever malware can look boring. Wrong verdict? Flag it above; confirmed false positives become regression tests.
