MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF sample contains a critical heuristic indicating exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader related to LibTIFF XFA image handling. This suggests the document is designed to execute arbitrary code upon opening in a vulnerable reader. No document body text or scripts were extracted, but the exploit itself is sufficient evidence of malicious intent.

    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
