MITRE ATT&CK

T1204.002 Malicious File: Malicious PDF T1059.001 Command and Scripting Interpreter: JavaScript

The PDF file contains XFA (XML Forms Architecture) data, which is known to be a vector for exploits. Specifically, the 'CVE_2010_0188' heuristic firing indicates exploitation of a vulnerability in Adobe Reader related to LibTIFF and XFA. The 'PDF_XFA_NUMERIC_JS_STAGER' heuristic suggests that JavaScript code was embedded and used as a stager, likely to download and execute a second-stage payload. The deobfuscated JavaScript, although not fully detailed here, is the primary mechanism for this execution. The embedded URL is likely related to the XFA schema but could also be a lure or part of the exploit chain.

Heuristics 6

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 JavaScript stager high PDF_XFA_NUMERIC_JS_STAGER

PDF XFA script reconstructs a hidden JavaScript stage from numeric field data or a character table, then evals the result. The decoder is gated on XFA script, numeric staging, and recovered exploit-like JavaScript or shellcode markers.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
