MITRE ATT&CK
T1204.002 Malicious File

The critical ClamAV heuristic identified the file as Pdf.Exploit.Dropped-78, indicating it's a known malicious PDF exploit. The presence of an XFA form, flagged by a low-severity heuristic, suggests the exploit targets this feature. An embedded URL was also found, likely used to download the secondary payload. The document body content is not indicative of user-facing lures.
