Abstract
The goal of this project was to show how vulnerable SSL-secured Remote Desktop Protocol communication using RSA is. This project will develop a method to capture authentication packets of an RDP session and decrypt the SSL key used. A secondary goal is to develop a method to replay the authentication packets with the RDP server after the snooped session has ended. The motivation of this project is to demonstrate the insecurity of RSA-encrypted SSL encryption in Remote Desktop Protocol connections used by many network operating systems. This project will build a Linux installation which can capture Remote Desktop Protocol packets and develop a method to decrypt the confidential communication between the client and the server. Database Security Techniques used in this project will include: access security in authentication to the operating system and encryption of data at rest because Linux hashes passwords in the users database of the operating system. This project will be exploiting access control to the RDP server. The secondary goal of this project will be to authorize an untrusted user to access confidential data assets. The expected result of this project is to successfully capture and monitor the packets associated with authentication to an RDP server and secondarily to be able to successfully masquerade as the previously authenticated user. Evaluations will include the ability to successfully capture 10 RDP sessions, decrypt them, and store the packet information into an SQL database.​

Our annual information security symposium will take place on April 3rd and 4th, 2018.
