| Technique | Description |
|-----------|-------------|
| Object Stream Obfuscation | Hides malicious content inside compressed /ObjStm objects that AVs may skip or mishandle. |
| JS/Launch Action Abuse | Uses /OpenAction or /Launch to execute commands or open external malicious files. |
| Cross-Platform Payloads | Embeds both PowerShell (Windows) and bash (macOS/Linux) scripts, activated depending on OS detection. |
| Encoding Layering | Applies multiple encodings (Hex → ASCII85 → FlateDecode) to obscure payloads from YARA rules. |
| PDF Parser Differential | Exploits how different PDF readers (Adobe vs. Chrome vs. macOS Preview) interpret malformed objects. |
| Stitching | Splits payload across multiple unreferenced objects; triggered by a specific event (e.g., page render). |
