An understanding of how to set up and use RDP.A virtual environment to run two Windows hosts like VirtualBox or VMware.The following are necessary to get the most value from this tutorial: This blog demonstrates how to prepare the environment, obtain a decryption key and use it to decrypt RDP traffic. Unfortunately, this encryption makes writing RDP signatures difficult because RDP content is hidden.įortunately, we can establish a test environment that provides a key file, and we can use that key to decrypt a packet capture (pcap) of the RDP traffic in Wireshark. Security professionals have increasingly focused their attention on this protocol by writing signatures to detect RDP vulnerabilities and prevent attacks.Īs a proprietary protocol from Microsoft, RDP supports several operating modes that encrypt network traffic.
Since 2017, RDP has become a significant vector in malware attacks using ransomware. In recent years, Remote Desktop Protocol (RDP) has been exploited by attackers to access unsecured servers and enterprise networks.
