MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that promote free in-game currency and items for popular games, acting as a lure. The primary external URI, http://netcdn.tw/app/406889139/coin-master-free-spin-bonus-game-hack, suggests a download or redirection to malicious content. The ML classifier's high confidence score further supports the malicious nature of this PDF.
