MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic firing indicates the PDF contains a known exploit. The presence of embedded JavaScript, identified by PDF_JAVASCRIPT and PDF_JS heuristics, strongly suggests that the script is responsible for triggering this exploit. The likely intent is to download and execute a second-stage payload, as is common with such exploit-laden PDFs. The document body was unreadable, providing no further context on the lure.
