MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs promoting game hacks and cheats. These URLs likely lead to the download of malicious applications or further phishing content. The presence of embedded URLs and the overall theme suggest a lure for users seeking unauthorized advantages in games, which is a common social engineering tactic.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
