MITRE ATT&CK

T1204 Malicious Link T1059 Command and Scripting Interpreter T1059.001 PowerShell T1059.003 Windows Command Shell T1059.007 JavaScript

The PDF file contains XFA (XML Forms Architecture) content, which is known to be a vector for exploits. Specifically, the 'CVE_2010_0188' heuristic indicates a vulnerability in Adobe Reader related to LibTIFF and XFA. The 'PDF_XFA_NUMERIC_JS_STAGER' heuristic suggests that JavaScript embedded within the XFA form is used as a stager to decode and execute further malicious code. This stager recovered 3750 bytes of JavaScript, which is likely responsible for downloading and executing a second-stage payload.

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.
