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

The PDF document contains numerous URLs pointing to sites offering free in-game currency and cheats for popular games, with one prominent URL being https://netcdn.xyz/app/431946152/roblox-play-as-guest-free-game-hack. The presence of a 'download button' heuristic and a high-confidence ML classifier flagging the PDF as malicious strongly suggests this document is a lure for downloading malware. No scripts were extracted from this sample.
