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

The PDF document contains numerous embedded URLs and a document body that promotes downloading applications related to game cheats and hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful content. The document's content and structure suggest it is a lure to download a second-stage payload.

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.
