MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent link and text related to 'Free Account Roblox Login', suggesting a phishing or credential harvesting attempt. The ML classifier also flagged the PDF as malicious. While no scripts were directly extracted, the presence of multiple external URLs and the nature of the lure indicate a malicious intent to redirect users to potentially harmful websites.

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
