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

The document body and extracted URLs indicate a lure for free in-game items, a common tactic for phishing or malware distribution. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external links reinforces the likelihood of a malicious workflow. The primary URL, http://netcdn.tw/app/406889139/free-spin-link-of-coin-master-game-hack, is a key indicator of the malicious intent.
