MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a URL that leads to a file named 'roblox-this-game-has-shut-down-cheat-engine-game-hack'. The presence of a download-related heuristic and the ML classifier flagging the PDF as malicious strongly suggest this is a lure for downloading a second-stage payload. The document body, though heavily obfuscated, contains references to the URL and the file name, reinforcing the malicious intent.
