| Feature | Description | |---------|-------------| | | Rearranges internal PDF objects (catalog, pages, streams) using a randomised graph algorithm, producing a structurally distinct file each time. | | Content‑Preserving Compression | Re‑compresses embedded streams (images, fonts) with varying filters (Flate, LZW, JPEG‑2000) while ensuring visual fidelity. | | Steganographic Payload Injection | Hides malicious JavaScript or shellcode inside seemingly innocuous objects (e.g., hidden metadata fields, low‑order bits of images). | | Polymorphic JavaScript Engine | Generates obfuscated JavaScript on‑the‑fly, employing custom variable renaming, dead‑code insertion, and string encryption. | | Anti‑Sandbox Tricks | Detects sandbox environment (e.g., low‑resolution screens, virtual CPU signatures) and alters payload delivery accordingly. |
