T1204 Malicious File Execution T1204.002 Malicious File Execution: Malicious Attachment T1059 Command and Scripting Interpreter

This PDF file contains embedded JavaScript and an embedded file, triggering heuristics related to PDF exploits and JavaScript actions. Specifically, the critical heuristic 'CVE_2010_0188' indicates exploitation of a LibTIFF vulnerability within Adobe Reader's XFA forms. The embedded file 'embedded_file_obj0004.bin' is likely the second-stage payload. The presence of JavaScript and the exploit suggests the document's primary purpose is to compromise the user's system by executing malicious code.

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
