MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent call-to-action related to "Coin Master Free Spins". The ML classifier flagged this PDF as malicious with high confidence. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-link-blogspot-2021-game-hack, is likely intended to deliver a secondary payload or lead to a phishing site. No scripts were extracted, but the presence of malicious links and the ML detection strongly suggest a phishing or malware distribution attempt.
