MITRE ATT&CK

The PDF contains a link to a known malicious redirector, which is likely intended to deliver a secondary payload or lead the user to a phishing site. The embedded URL suggests a lure related to game mods, aiming to trick users into clicking. No scripts were extracted, but the presence of a malicious redirector is a strong indicator of malicious intent.

  • Embedded URL info EMBEDDED_URL
