MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains a heuristic indicating an external URI and a machine learning classifier flagged it as malicious. The document body, though heavily obfuscated, contains text related to 'Robux' and a URL that appears to be a lure for free Robux. This suggests the document is designed to trick users into visiting a malicious site to download a payload.
