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. Specifically, the critical heuristic firing indicates the presence of a payload targeting CVE-2010-0188, an Adobe Reader vulnerability. This exploit likely allows for arbitrary code execution upon opening the document.

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
