MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript and an embedded file, triggering heuristics related to PDF JavaScript and embedded files. Crucially, it fires a critical heuristic for CVE-2010-0188, indicating exploitation of a vulnerability in Adobe Reader via an XFA image payload. The embedded JavaScript, though minimal, suggests an attempt to initiate malicious actions. The embedded file is likely the payload.

Heuristics 7

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
AcroForm button with action trigger low PDF_ACROFORM_BUTTON

PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
