MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text referencing free in-game currency and cheats for games like Coin Master and Roblox. The primary URL, http://netcdn.tw/app/406889139/coin-master-spin-link-free-game-hack, suggests a lure for users seeking game exploits. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent. No scripts were extracted, but the presence of external links and the lure content points to a phishing or malware distribution attempt.
