MITRE ATT&CK

T1190 Exploit Public-Facing Application

The critical heuristic firing indicates the sample exploits CVE-2010-0188, a vulnerability in Adobe Reader related to XFA forms and TIFF images. This suggests the PDF is designed to deliver a payload by exploiting this specific flaw. No JavaScript or other scripts were extracted, and the document body was not readable, but the exploit itself is sufficient to determine the attack pattern. The embedded file is likely the payload.

Heuristics 6

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

JavaScript action low PDF_JAVASCRIPT

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
