MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that promotes free game-related content such as "Free Wallpapers For Roblox" and hacks, likely as a lure. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious site for downloading further payloads or engaging in phishing. No scripts were extracted, but the overall pattern indicates a phishing or malware distribution attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
