MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment T1190 Exploit Public-Facing Application

The PDF file contains XFA (XML Forms Architecture) data and triggers critical heuristics for CVE-2010-0188, an exploit targeting Adobe Reader's LibTIFF component. This indicates the document is designed to exploit this vulnerability to execute arbitrary code. The presence of an embedded URL, though benign in reputation, is typical for downloaders. The XFA numeric eval stager heuristic further supports the exploit execution path.

Heuristics 5

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
    PDF contains the CVE-2010-0188 exploit template: XFA JavaScript heap-spray setup, a generated TIFF image payload, and assignment of that TIFF data to an XFA image field rawValue to trigger Adobe Reader's LibTIFF parser.
  • ClamAV: Pdf.Exploit.Dropped-78 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Exploit.Dropped-78
  • XFA numeric character-table eval stager high PDF_XFA_NUMERIC_EVAL_STAGER
    PDF XFA initialize script reads numeric form data from rawValue, maps the values through a short character table, and evals the reconstructed stage. This is an exploit-kit staging technique even when the final decoded layer remains encoded.
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
