MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous embedded URLs and a lure related to obtaining free in-game items, strongly suggesting a phishing or scam attempt. The ML classifier also flagged the PDF as malicious. While no scripts were directly extracted, the presence of embedded URLs and the overall theme indicate a likely attempt to redirect users to malicious sites for further exploitation or credential harvesting.

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.
