MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains numerous embedded links, many of which are presented as a link farm for game-related hacks and cheats. The primary URL http://netcdn.co/app/431946152/free-costume-roblox-glitch-game-hack is directly associated with the document's apparent lure. The presence of a 'download button' heuristic and the ML classifier's high confidence score indicate a malicious intent to direct users to potentially harmful content.
