MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and document body text that promote 'hacks' and 'free items' for Roblox, aiming to trick users into clicking malicious links. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were extracted, the presence of external URIs and the overall lure suggest a phishing or malware distribution attempt.

  • Urgency / deadline lure low SE_URGENCY_LURE

  • 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.
