MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a visible call-to-action button, suggesting a phishing or social engineering attempt. The ML classifier also flagged the PDF as malicious. The document body and embedded links promote methods to obtain free followers or in-game currency, which is a common lure for downloading malware.
