MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous external URLs, with one prominent URL pointing to a site offering game hacks and free spins. The ML classifier strongly flagged this PDF as malicious, indicating a high likelihood of it being used for phishing or malware distribution. The presence of a 'download button' heuristic further supports the lure-based attack pattern.
