MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains an embedded JavaScript stream and an XFA form that triggers an exploit for CVE-2010-0188, a vulnerability in Adobe Reader's handling of LibTIFF images within XFA forms. This exploit is designed to download and execute a second-stage payload, as indicated by the critical ClamAV detection and the embedded file artifact. The document body appears to be malformed or encrypted, providing no direct user-facing lure.

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
