T1059.001 PowerShell T1204.002 Malicious Link

The PDF document contains numerous embedded URLs, many of which appear to be lures for book or music-related content. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates that the document likely instructs the user to open a password-protected archive, suggesting a multi-stage attack where the archive contains the actual malicious payload. The ML classifier also flagged this PDF as malicious. The presence of multiple external URIs points towards a delivery mechanism for further malicious content.
