T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and text referencing 'Free Robux' and game hacks, indicating a lure for potentially unwanted software or scams. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs suggests the document may attempt to download further payloads or redirect users to malicious sites.
