MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution T1059 Command and Scripting Interpreter T1059.001 Command and Scripting Interpreter: PowerShell

The critical ClamAV heuristic 'Pdf.Exploit.Dropped-156969-1' indicates the file is a known PDF exploit. The 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic further suggests that a script is embedded within the PDF stream, likely responsible for triggering the exploit. This script is presumed to download and execute a second-stage payload, aligning with the attack pattern of exploiting PDF vulnerabilities for initial access. No specific family could be identified.

Heuristics 5

ClamAV: Pdf.Exploit.Dropped-156969-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-156969-1
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
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
