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

The document contains multiple embedded URLs and a critical heuristic firing for a 'secret recovery' lure, indicating it's designed to trick users into revealing sensitive information or downloading malware. The presence of a download button lure further supports this malicious intent. The primary URL suggests a lure for game-related cheats or hacks.

  • 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.
