MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file utilizes XFA forms and contains an embedded script payload, as indicated by the 'PDF_XFA' and 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristics. ClamAV detection 'Pdf.Exploit.Agent-6136306-0' confirms its malicious nature. The embedded script is likely responsible for downloading and executing a second-stage payload, though its exact functionality is obscured by obfuscation. The presence of XFA suggests an exploit targeting Adobe Reader or similar software.
