MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent external URI pointing to resources advertising hacks for popular games like Coin Master. The ML classifier flagged this PDF as malicious with high confidence. The presence of these lures suggests an attempt to trick users into downloading further malicious content, likely a second-stage payload.
