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

The ML classifier strongly indicates maliciousness, supported by the presence of external URIs and embedded URLs pointing to game-related downloads. The document body contains text and URLs that suggest a lure for downloading game cheats or free in-game currency, likely a social engineering tactic to trick users into downloading malware or unwanted software. The heuristic 'SE_DOWNLOAD_BUTTON' further reinforces the social engineering aspect.

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.
