MITRE ATT&CK

T1204 Malicious File T1204.002 Malicious File: User Execution: Malicious Attachment

The PDF was flagged by multiple high-confidence heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-6136306-0'. The presence of an XFA form and an embedded script payload indicates a likely exploit attempt. The ML classifier also strongly indicated maliciousness. The embedded script is likely responsible for executing the exploit or downloading a secondary payload.
