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

The PDF contains embedded links that point to known malicious redirector infrastructure, specifically targeting users with lures related to games like Minecraft and Roblox. The presence of a visual download button further reinforces the social engineering attempt to trick users into clicking the malicious link and downloading a payload. No scripts were extracted, but the primary malicious function appears to be redirecting users to a harmful site.

  • 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
  • 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.
