MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, with one prominent URL pointing to a site offering 'how to get followers on tiktok for free'. The ML classifier strongly flagged this PDF as malicious. The presence of a download button lure and the nature of the embedded URLs suggest a social engineering attempt to trick the user into downloading a malicious payload or visiting a phishing site.
