MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that lure the user towards websites promising free in-game currency (Robux, Coin Master spins). The ML classifier flagged this PDF as malicious, and the presence of multiple suspicious URLs reinforces this finding. The document body explicitly mentions 'CLICK HERE TO ACCESS ROBLOX GENERATOR', indicating a phishing or scam attempt.
