MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document body contains numerous URLs related to game cheats and free currency. The presence of embedded URLs, specifically http://netcdn.co/app/431946152/roblox-cool-t-shirts-free-marshello-game-hack, suggests the document is designed to redirect users to a site that likely hosts a malicious payload or exploits. No scripts were extracted, but the overall pattern is consistent with a phishing lure to download malware.

Heuristics 3

  • 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.
