MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains an embedded URI pointing to a suspicious domain, and the ML classifier flagged it as malicious. The document body, though garbled, includes references to game-related cheats and free currency, suggesting a lure to download further content. The presence of multiple URLs related to game exploits and hacks reinforces the malicious intent.
