MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains an embedded JavaScript stream and an XFA form, which are leveraged by the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader's handling of TIFF images within XFA forms. The critical ClamAV detection and the embedded file further indicate malicious intent. The primary attack vector is the exploitation of a known vulnerability for initial code execution.

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
