T1204.002 Malicious File T1566.001 Spearphishing Attachment

The file is a PDF document flagged by ClamAV as Pdf.Exploit.Agent-21940. A machine learning classifier also assigned a high probability of maliciousness. An embedded file was detected, suggesting the PDF is a dropper for a secondary payload. The document body is unreadable, but the combination of heuristics and the ClamAV signature strongly indicates a PDF exploit delivery mechanism.
