MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises a "Roblox Btools Hack", suggesting a lure for users to download a malicious file. The ML classifier also flagged this PDF with high confidence. While no scripts were directly extracted, the presence of external URIs and the nature of the lure indicate a phishing or social engineering attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
