Using **Remote Desktop Protocol (RDP)** can be convenient, but it comes with several security risks, especially if not configured properly. Here are some key risks: ### 1. [[Brute Force Attacks]] - Hackers often try to guess weak passwords through automated scripts. If your RDP port is open to the internet, it's a prime target for brute force attacks. ### 2. **Ransomware & Malware** - Many ransomware attacks exploit RDP vulnerabilities to gain access to a network, encrypt files, and demand payment. ### 3. **Man-in-the-Middle (MitM) Attacks** - If RDP sessions are not encrypted properly, attackers can intercept and modify traffic, potentially stealing sensitive data. ### 4. **Exploitation of Vulnerabilities** - Older or unpatched versions of RDP (like the **BlueKeep vulnerability** in older Windows versions) can be exploited by attackers to gain full control of a system. ### 5. **Credential Theft** - Attackers can use tools like **Mimikatz** to extract credentials from memory once they gain access to an RDP session. ### 6. **Denial of Service (DoS) Attacks** - RDP services can be overwhelmed with requests, making remote access impossible. ### 7. **Unauthorized Access via Weak Configurations** - If Network Level Authentication (NLA) is disabled or if default ports are used (3389), attackers have an easier time gaining access. ## **How to Secure RDP** ✅ **Use strong, complex passwords** ✅ **Enable Network Level Authentication (NLA)** ✅ **Change the default RDP port (3389) to a non-standard one** ✅ **Limit RDP access to specific IP addresses** ✅ **Use a VPN or Remote Desktop Gateway** ✅ **Keep Windows & RDP updated** ✅ **Enable account lockout policies to prevent brute force attacks** ✅ **Use multi-factor authentication (MFA)** ✅ **Monitor RDP logs for suspicious activity** RDP can be secure if properly configured, but if left exposed, it’s a major security risk.
