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

The PDF contains multiple embedded URLs and document body text that explicitly advertise game hacks for popular titles like Roblox and Coin Master. The primary URL, http://netcdn.tw/app/431946152/roblox-build-a-boat-for-treasure-fly-hack-game-hack, likely leads to a malicious download. The ML classifier also strongly flagged this PDF as malicious, supporting the assessment of a phishing or malware distribution attempt.
