MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

This PDF file contains embedded JavaScript and an embedded file, which are indicators of malicious intent. The critical heuristic firing for CVE-2010-0188 indicates that the file exploits a known vulnerability in Adobe Reader related to XFA forms and LibTIFF image parsing. This exploit likely leads to the execution of arbitrary code, as suggested by the ClamAV detection of Pdf.Exploit.Agent-36015. The embedded file, 'embedded_file_obj0004.bin', is likely a secondary payload.

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
