T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous embedded URLs and a document body that mimics a 'how-to' guide for obtaining in-game currency or items for popular games. The primary URL, http://netcdn.tw/app/431946152/how-to-play-heroes-online-roblox-for-free-game-hack, suggests a lure for potentially unwanted or malicious downloads. The ML classifier also strongly flagged this PDF as malicious, indicating a high likelihood of malicious intent.
