MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URI pointing to a suspicious URL promising free TikTok likes, and the document body includes similar text and a call-to-action. The ML classifier also flagged the PDF as malicious. The presence of multiple links to other PDF files on a similar domain suggests a downloader or redirector pattern.
