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

The PDF document contains numerous embedded URLs, with a primary focus on luring users to download game-related cheats or currency. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. The document's content and embedded links suggest it is a phishing lure designed to trick users into downloading a second-stage payload.
