MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a visual call-to-action button, directing users to a website that promises free TikTok fans. This is a common lure for scams or phishing. The ML classifier also flagged the PDF as malicious, increasing confidence in its suspicious nature. No scripts were extracted, but the presence of external links suggests a potential for further malicious activity.
