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

The PDF document contains numerous embedded URLs and a document body that explicitly advertises 'hacks' for popular games, aiming to trick users into clicking malicious links. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful content. The primary IOC is the most prominent URL associated with the 'hack' theme.
