MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains an XFA form, which is a known vector for exploitation. A critical ClamAV heuristic identified it as 'Pdf.Exploit.Agent-6136306-0', indicating a known exploit. An embedded script payload was also detected, suggesting the PDF is designed to download and execute a second-stage payload. The embedded URLs, while not directly malicious, are related to XFA and Adobe, which are often part of exploit chains.
