MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are hosted on `netcdn.tw` and `nlcitychurch.org.hk`, and are presented as cheats or free currency for games. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of it being used to distribute malware or lead users to phishing sites. The presence of embedded URLs and the lure of free in-game items suggest a social engineering tactic to trick users into downloading further malicious content.
