MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The ML classifier strongly flagged this PDF as malicious. The document body and embedded URLs point to lures for free in-game currency, specifically for Coin Master and Roblox, which are common social engineering tactics. The presence of embedded URLs suggests an attempt to redirect the user to a malicious website for phishing or malware distribution. No scripts were extracted from this sample, but the overall pattern is consistent with a phishing or credential harvesting attempt.

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.
