MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript and an XFA form, which are often used to deliver exploits. Specifically, the 'CVE_2010_0188' heuristic indicates exploitation of the LibTIFF vulnerability in Adobe Reader. This exploit likely leads to the execution of arbitrary code, as suggested by the 'PDF_JAVASCRIPT' and 'PDF_JS' firings. An embedded file was also detected, which could be a secondary payload.

Heuristics 8

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

ClamAV: Pdf.Exploit.Agent-36015 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36015
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
