The Threat is Real
RDP brute force attacks have increased by over 400% in recent years. Every exposed Windows server with RDP enabled is a potential target, being probed by automated bots thousands of times per day.
What is an RDP Brute Force Attack?
Attackers use automated tools to try thousands of username/password combinations against your RDP port (3389) until they find a match. Once in, they can deploy ransomware, steal data, or use your server as a launch point for further attacks.
How to Protect Yourself
The most effective measures are: use a non-standard port, implement account lockout policies, enforce MFA, use a VPN for remote access, and deploy a dedicated RDP protection tool like Zopi Guard.
Zopi Guard
We built Zopi Guard specifically to address this problem. It monitors your Windows Event Log in real-time, detects brute force patterns, and automatically blocks offending IP addresses before they succeed.
