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

The ML classifier strongly indicated maliciousness, and the document body contains multiple URLs promoting game hacks for Roblox and Coin Master. These URLs likely lead to the download of a second-stage payload, such as malware or exploit kits, designed to compromise the user's system. The presence of a visual download button further supports the lure.

  • 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.
