MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains embedded URLs, one of which is directly referenced by a heuristic indicating an external URI. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic suggests the document is designed to trick the user into downloading a password-protected archive, likely by providing instructions or a link to it. The ML classifier also flagged this PDF as malicious. The primary IOC is the external URI found within the document.
