MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains an embedded script payload and triggers a critical ClamAV detection for Pdf.Exploit.Agent-6136306-0. The presence of XFA forms and embedded scripts suggests an exploit targeting PDF viewer vulnerabilities. The embedded script is likely responsible for downloading and executing a second-stage payload, as indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic. The document body's content is heavily obfuscated and does not provide clear user-facing text.
