MITRE ATT&CK

T1204.002 Malicious File

The PDF was flagged as malicious by a machine learning classifier and ClamAV, specifically identified as Pdf.Exploit.Agent-36874. Static analysis revealed the presence of XFA forms and AcroForm buttons with action triggers, common elements in exploit-laden PDFs. An embedded, decompressed stream artifact suggests the potential for further malicious activity, likely the download and execution of a second-stage payload.
