MITRE ATT&CK
T1204.002 Malicious File: Malicious File

The PDF file contains embedded JavaScript with an eval() call, indicating an attempt to execute arbitrary code. The presence of ASCIIHexDecode filter with exploit indicators further suggests a vulnerability is being leveraged. The script's purpose is likely to download and execute a second-stage payload, though the exact mechanism is obfuscated.

Heuristics 5

  • eval() call high PDF_EVAL
    eval() found — commonly used for obfuscated exploit execution
  • ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX
    Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
  • JavaScript action low PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
