MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript and an XFA form, which are commonly used to deliver exploits. A critical heuristic firing identified the CVE-2010-0188 exploit, targeting a vulnerability in Adobe Reader's LibTIFF component. This exploit likely leads to the execution of a secondary payload from the embedded file.

Heuristics 6

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
