MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.007 JavaScript

This PDF file is identified as malicious due to the critical CVE-2010-0188 heuristic, indicating an exploit for Adobe Reader's LibTIFF component. The presence of XFA forms and embedded script payloads further supports this, suggesting the document is designed to execute arbitrary code. The embedded file, 'embedded_file_obj0008.bin', is likely the second-stage payload.

Heuristics 9

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.
XFA form contains risky executable script high CVE related PDF_XFA_SCRIPT

PDF embeds an XFA form whose script block contains exploit, submission/launch, or shell-execution primitives. Ordinary LiveCycle print/update scripts are left as generic XFA/JS signals unless stronger behavior is present.
ClamAV: Pdf.Exploit.Dropped-93 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-93
eval() call high PDF_EVAL

eval() found — commonly used for obfuscated exploit execution
Embedded file low PDF_EMBEDDED

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
Embedded script payload in PDF stream low PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
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.
