MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The PDF file contains an embedded object and triggers a critical heuristic for CVE-2010-0188, indicating an exploit targeting Adobe Reader's LibTIFF XFA image processing. This suggests the file is designed to deliver a malicious payload via a known vulnerability. No scripts were extracted, and the document body was unreadable, but the exploit itself is sufficient evidence of malicious intent.

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.
Embedded script payload in PDF stream medium 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.
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
