MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious File T1059.001 PowerShell

The PDF file contains embedded JavaScript and an embedded file, triggering heuristics for PDF_JS, PDF_EMBEDDED, and EXTRACTED_FILE_STATIC_TRIAGE. Crucially, it fires a critical heuristic for CVE_2010_0188, indicating exploitation of a known Adobe Reader vulnerability via an XFA image payload. This suggests the primary goal is to leverage this exploit to deliver a secondary payload, likely downloaded from a remote source.

Heuristics 6

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

PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
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
