MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains multiple embedded URLs and a prominent external URI pointing to game-related cheats and hacks. The ML classifier strongly indicates maliciousness, and the presence of download-oriented text suggests a lure to download a second-stage payload. The primary IOC is the external URI, which likely hosts the malicious content.
