The PDF file contains an embedded artifact and triggers a critical heuristic for CVE-2010-0188, indicating it exploits a vulnerability in Adobe Reader's handling of XFA forms and TIFF images. This suggests the file is designed to deliver a second-stage payload via this exploit. No scripts were extracted, and the document body was unreadable.

Heuristics 4

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188

    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
