T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains an embedded URI pointing to a game hack, and the ML classifier strongly flagged it as malicious. The document body, though heavily obfuscated, contains text related to game mods and a URL that likely serves as a lure for downloading malicious content. The presence of multiple suspicious URLs further supports the malicious intent.
