MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document presents itself as a download for Minecraft Java Edition, but contains numerous embedded URLs pointing to various game-related cheats, free spins, and accounts, suggesting a lure for potentially unwanted software or scams. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs indicates an attempt to redirect the user to malicious sites. No scripts were extracted from this sample.

Heuristics 4

  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
  • 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.
