MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The document contains a lure for downloading a game, specifically Minecraft, and includes a link to an external URL that likely hosts a malicious payload. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a download button lure and the remote support lure heuristic suggest a social engineering attempt to trick the user into downloading and potentially executing further malicious content.

  • Nyx PDF Classifier malicious score 0.9580

Heuristics 4

  • Remote-support tool lure high SE_REMOTE_SUPPORT_LURE
    Document instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited document
  • 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.
