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

The PDF document contains embedded URLs and a document body that explicitly mentions hacking tools and game cheats, such as 'Coin Master' and 'Lucky Patcher'. The presence of multiple URLs pointing to similar content, combined with a high ML classifier score, indicates a strong likelihood of malicious intent. The document likely serves as a lure to download a second-stage payload.
