MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a visual download button, suggesting a lure to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious. While no scripts were directly extracted, the presence of external URIs and the lure indicate an attempt to trick the user into downloading a second-stage payload.
