MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is a PDF file that contains embedded JavaScript and an XFA form. A critical heuristic firing indicates the presence of the CVE-2010-0188 exploit, targeting Adobe Reader's XFA image processing. This exploit likely allows for arbitrary code execution upon opening the document. No specific malware family was identified, but the exploit is the primary indicator of malicious intent.

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
