Archive Traversal Checks

Detects Zip-Slip directory traversal attempts, recursive bombs, and double extensions.

Macro & Script Detection

Flags embedded JavaScript in PDFs and suspicious VBA macros inside documents.

Zero-Execution Sandbox

Files are evaluated purely as byte arrays and structured trees with zero runtime execution.
