MITRE ATT&CK

T1204.002 Malicious File T1566.001 Spearphishing Attachment

This PDF file is identified as malicious by ClamAV (Pdf.Exploit.Agent-36015) and contains a critical heuristic indicating exploitation of CVE-2010-0188 via an embedded XFA image. The presence of JavaScript actions and an embedded file further supports the likelihood of a multi-stage attack. The primary attack vector appears to be exploiting a known Adobe Reader vulnerability to deliver a payload.

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
