MITRE ATT&CK
T1204 Malicious Link T1204.001 Malicious Link: Malicious Link T1204.002 Malicious Link: Malicious File

The PDF file contains an embedded XFA form and triggers the CVE-2010-0188 exploit for Adobe Reader. This exploit is known to deliver a second-stage payload. The presence of ASCIIHexDecode and ASCII85Decode filters further indicates obfuscation commonly used in malicious PDFs.

Heuristics 5

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
    PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
  • 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
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85
    ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
