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

The PDF document contains an embedded URL and text that explicitly promises a 'how to hack into Roblox for Robux' exploit. The ML classifier strongly flagged this PDF as malicious, and the presence of a download-related heuristic further supports a malicious intent. The primary IOC is the external URL, which likely hosts the malicious payload.
