MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that suggests a lure for downloading a "Hacker Roblox" tool. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs indicates an attempt to redirect the user to download potentially harmful content. No scripts were extracted, but the overall structure and content point towards a phishing or malware distribution attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
