MITRE ATT&CK

T1204.002 Malicious File T1566.002 Spearphishing Attachment

The file is a PDF document identified by ClamAV as Pdf.Exploit.Agent-36928, indicating a known exploit. The presence of embedded files and an embedded URL further supports the likelihood of a malicious exploit attempting to download and execute a secondary payload. The XFA form structure is also a common vector for PDF exploits.

Heuristics 4

ClamAV: Pdf.Exploit.Agent-36928 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36928
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
