Detection & IOCsextracted from sources · hover to see the quote

  • Vulnerability is in the JScript9 scripting engine component of Windows; monitor for suspicious JScript9 execution or memory corruption events triggered via browser/scripting engine interactions
  • Attack vector requires a user to access a malicious server share or website; monitor for users connecting to unexpected SMB shares or web resources, particularly those delivered via email or chat lures
  • ·Exploitation likelihood is rated 'More Likely' for the latest software release, despite no confirmed in-the-wild exploitation at time of publication; prioritize patching accordingly
  • ·User interaction is required for exploitation — the attacker cannot force visits to the malicious resource, relying instead on social engineering via email or chat
