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

The document presents lures for game cheats and in-game currency, directing users to download potentially malicious files from external URLs. The presence of a remote support lure, combined with the ML classifier's high confidence, indicates a strong likelihood of malicious intent. The document's content and embedded URLs suggest a social engineering tactic to trick users into downloading malware.

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.
