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

The PDF document contains numerous links to external websites, including one at http://netcdn.co/app/431946152/infinite-moneyz-roblox-injector-hack-game-hack, which likely hosts a malicious payload. The document body and embedded URLs suggest a lure for downloading game cheats or hacks, a common social engineering tactic. The ML classifier also strongly indicated maliciousness.
