MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to hacking game accounts, specifically Roblox, and directs users to download a file from a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the embedded URL is a primary indicator of a potential download or exploit delivery mechanism. While no scripts were explicitly extracted, the nature of the content suggests a phishing or social engineering attempt to trick users into downloading a malicious payload.

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