How to Download and Install the BlueKeep Patch
BlueKeep is a critical remote code execution vulnerability that affects the Remote Desktop Service on some versions of Windows. It allows an unauthenticated attacker to execute arbitrary code on a vulnerable system by sending a specially crafted request to the Remote Desktop Protocol (RDP) service. This vulnerability is "wormable", meaning that it can spread from one system to another without user interaction, similar to how WannaCry and Conficker infected millions of computers worldwide.

If your system is not vulnerable to BlueKeep, you don't need to download and install the patch. However, you should still follow the best practices for securing your RDP service, which we will discuss later in this article.
Step 2: Download the appropriate patch from Microsoft
If your system is vulnerable to BlueKeep, you need to download the appropriate patch from Microsoft's website. You can find the links to the patches for different versions of Windows in Microsoft's security advisory page. You can also use Windows Update or Microsoft Update Catalog to download and install the patch automatically.
Make sure that you download the correct patch for your system architecture (32-bit or 64-bit) and language. You can check these details by right-clicking on My Computer or This PC and selecting Properties. You should also verify that the patch file has a valid digital signature from Microsoft before installing it.
Step 3: Install the patch and restart your system
After you download the patch file, you need to install it on your system. You can do this by double-clicking on the file and following the instructions on the screen. You may need to accept the license agreement and provide an administrator password if prompted. The installation process may take a few minutes depending on your system configuration.
Once Once the patch is installed, you need to restart your system for the changes to take effect. You can do this by clicking on Start, then Power, then Restart. Alternatively, you can use the command prompt or PowerShell to restart your system by typing shutdown /r and pressing Enter.
After your system restarts, you should check if the patch has been applied successfully. You can do this by using the same tools that you used to check your system's vulnerability in Step 1. If the tools show that your system is no longer vulnerable to BlueKeep, congratulations! You have successfully downloaded and installed the BlueKeep patch.
How to Protect Your System from BlueKeep Attacks
Downloading and installing the BlueKeep patch is the most effective way to protect your system from BlueKeep attacks. However, there are some other measures that you can take to enhance your system's security and prevent unauthorized access to your RDP service. Here are some of them:
Enable Network Level Authentication (NLA) for Remote Desktop Protocol (RDP)
Network Level Authentication (NLA) is a security feature that requires users to authenticate themselves before establishing a remote desktop session. This prevents attackers from exploiting BlueKeep without valid credentials. NLA is enabled by default on Windows 10 and Windows Server 2019, but not on older versions of Windows. Therefore, you should enable NLA on your system if it supports it.
To enable NLA on your system, follow these steps:
Open the Control Panel and click on System and Security.
Click on System and then Remote settings.
Under Remote Desktop, select Allow connections only from computers running Remote Desktop with Network Level Authentication.
Click OK and close the Control Panel.
Note that enabling NLA may prevent some older or incompatible RDP clients from connecting to your system. You may need to update or replace these clients with newer or compatible ones.
Move the RDP listener behind a second factor authentication, such as VPN, SSL Tunnel, or RDP gateway
Moving the RDP listener behind a second factor authentication means that users need to provide an additional layer of security before accessing your system via RDP. This can be a VPN (Virtual Private Network), an SSL Tunnel, or an RDP gateway. These methods encrypt and protect your RDP traffic from being intercepted or tampered with by attackers. They also limit the exposure of your RDP service to the internet, reducing the chances of being targeted by BlueKeep or other RDP exploits.
To move the RDP listener behind a second factor authentication, you need to configure your network settings and firewall rules accordingly. You also need to install and configure the appropriate software or hardware on both your system and the client devices. The exact steps may vary depending on the method you choose and your network environment. You can consult Microsoft's documentation or a network administrator for more guidance.
Disable RDP if you don't need it or limit its access to trusted networks
If you don't use RDP at all or only use it occasionally, you may consider disabling it altogether or limiting its access to trusted networks. This will prevent any unauthorized or malicious attempts to connect to your system via RDP. You can disable RDP by following these steps:
Open the Control Panel and click on System and Security.
Click on System and then Remote settings.
Under Remote Desktop, select Don't allow remote connections to this computer.
Click OK and close the Control Panel.
If you still need to use RDP occasionally, you can enable it temporarily when needed and disable it when not in use. You can also limit its access to trusted networks by using firewall rules or IP filters. For example, you can allow only specific IP addresses or ranges to connect to your system via RDP and block all others. You can configure these settings using Windows Firewall or a third-party firewall software.
How to Detect and Respond to BlueKeep Exploits
Even if you have patched and protected your system from BlueKeep attacks, you should still monitor your system for any signs of compromise or exploitation. This will help you identify and respond to any potential threats as soon as possible. Here are some ways to detect and respond to BlueKeep exploits:
Use a vulnerability scanner or a network monitoring tool to identify any attempts to exploit BlueKeep on your system
A vulnerability scanner or a network monitoring tool can help you detect any attempts to exploit BlueKeep on your system by scanning your network for open RDP ports and checking their vulnerability status. They can also alert you of any suspicious activity or anomalies on your network or system. Some examples of these tools are Tenable Nessus, Shodan, Nmap, Wireshark, and Snort. You can use these tools regularly or on-demand to scan your system for BlueKeep vulnerability or exploits.
Review your system logs and alerts for any suspicious activity or anomalies
Your system logs and alerts can provide valuable information about the status and activity of your system and RDP service. They can help you identify any unauthorized or abnormal access, changes, or errors on your system. You can review your system logs and alerts using the Event Viewer or a log management software. You should look for any events related to RDP, such as connection attempts, failures, successes, disconnections, or errors. You should also look for any events related to system performance, security, or application issues.
If you find any suspicious or unusual events in your logs or alerts, you should investigate them further and take appropriate actions. For example, you can block or report the source IP address of the suspicious connection attempt, restore your system to a previous state, or scan your system for malware.
Contact Microsoft or a security expert if you suspect that your system has been compromised by BlueKeep
If you suspect that your system has been compromised by BlueKeep, you should contact Microsoft or a security expert as soon as possible. They can provide you with guidance and assistance on how to recover your system and prevent further damage. You can contact Microsoft's support team through their website or phone number. You can also contact a security expert through a reputable security company or organization.
