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

The PDF document contains embedded URLs and text that explicitly promise hacks or free currency for games like Roblox and Coin Master. The primary URL, http://netcdn.tw/app/431946152/hack-pour-avoir-des-robux-game-hack, is directly associated with the lure. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent. The document's content and the presence of external links suggest an attempt to trick users into downloading a secondary payload.
