How the analysis works

1. Signature Scan — The code is checked against a library of known malware patterns, obfuscators, and attack techniques used in real-world threats.

2. Structure Analysis — The code structure is examined for suspicious patterns such as heavily disguised variable names, hidden strings, and unusual logic flows commonly used to hide malicious intent.

3. Live Execution — The code is actually run in a fully isolated environment with no internet access. Any attempt to steal data, redirect users, or communicate with external servers is caught and reported.
