MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.002 Spearphishing Attachment

The PDF file contains an embedded script payload and triggers the CVE-2010-0188 exploit, indicating it is designed to deliver a malicious payload upon opening in a vulnerable application. The embedded artifact 'embedded_file_obj0008.bin' is likely the delivered payload. The XFA form and embedded file heuristics further support the exploit delivery mechanism.

Heuristics 6

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188

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
