MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file exploits the CVE-2010-0188 vulnerability in Adobe Reader's handling of XFA forms and embedded TIFF images. This exploit allows for arbitrary code execution on the victim's machine. No JavaScript or VBA scripts were extracted, and the document body contained only metadata and structural information, indicating the exploit is likely embedded within the XFA form itself.

Heuristics 6

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

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
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
