Microsoft Windows is affected by a vulnerability in its Internet Key Exchange (IKE) protocol. IKE is used to set up secure VPN tunnels in Windows.

Attackers can potentially cause a denial of service (DoS) on impacted systems by sending specially crafted IKE packets. This can cause the IKE service to stop responding, preventing VPN connections from being established.

While remote code execution is not possible with this vulnerability, a DoS can still disrupt connectivity and network access. Systems running default Windows configurations without any patches applied are vulnerable.

The best way to protect yourself is to ensure your Windows operating system and network drivers are updated with the latest security patches from Microsoft. You can enable automatic updates or manually check for updates and install any that are available.

Using a firewall can also help limit the attack surface by blocking unauthorized network connections. Be cautious of any suspicious network activity and avoid connecting to untrusted wireless networks when possible until your system has been patched.

Staying on top of software updates is one of the most effective ways to enhance the security of your device and reduce vulnerabilities that may be exploited by threat actors. Prioritize installing updates as they become available from Microsoft.
