MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that lures users with promises of free Robux and game hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect users to download further content. No scripts were extracted from this sample, but the overall pattern indicates a phishing or malware distribution attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
