The PDF document contains an embedded file and triggers the CVE-2010-0188 exploit, which is known to target Adobe Reader's LibTIFF component. This indicates the document is designed to deliver a malicious payload by exploiting this specific vulnerability. The XFA form structure is also indicative of exploit delivery mechanisms.

Heuristics 4

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

  • Embedded file low PDF_EMBEDDED
    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
