MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a prominent link and call-to-action text related to a 'Coin Master Hack'. The ML classifier strongly flagged this PDF as malicious, and the embedded URL points to a suspicious domain associated with such lures. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest a phishing or malware distribution attempt.
