Remote Desktop Protocol (RDP) attack. Remote Desktop Protocol (RDP) is a protocol for remote access to Windows systems (SSH is used with Linux). Attackers use automated systems to scan the internet for open ports which are only protected via a username and password. Shodan is an internet port scanner which show more than 4M ports open on the internet with the Netherlands on #5 (see figure. Having the same problem as you, with a continuous stream of brute force attacks against our RDP server, I had to implement an automated blocking script as well. Because our firewall is Linux based, it currently just counts SYN packets in the last week to the RDP port, and if it exceeds a certain threshold it blocks the IP(only if it's an external IP). This has a major flaw though. If I need to. Don't expose RDS/RDP to the internet — if you do, I strongly suggest you implement multi-factor authentication. You can use things like Microsoft RD Gateway or Azure Multi-Factor Authentication Server to get very low cost multi-factor authentication. If you're exposing RDP directly to the internet and somebody creates a local user or your domain users have easy to guess or reused. If RDP is enabled, threat actors have a way to move laterally and maintain presence in the environment through tunneling or port forwarding. To mitigate vulnerability to and detect these types of RDP attacks, organizations should focus on both host-based and network-based prevention and detection mechanisms Crowbar (formally known as Levye) is a brute forcing tool that can be used during penetration tests. It was developed to brute force some protocols in a different manner according to other popular brute forcing tools. As an example, while most brute forcing tools use username and password for SSH brute force, Crowbar uses SSH key (s)
RDP Clients Exposed to Reverse RDP Attacks by Major Protocol Issues. By. Sergiu Gatlan. February 5, 2019. 09:03 AM. 2. Multiple major vulnerabilities were discovered in the Remote Desktop Protocol.

I run a detection lab in Azure and at some point, it just started to be more annoying to me than I thought and instead of closing access to RDP, I decided to try another approach. With Quest InTrust it is possible. RDP Pivoting with Metasploit. In our previous tutorial we had discussed on SSH pivoting and today we are going to discuss RDP pivoting. Pivoting is a technique to get inside an unreachable network with help of pivot (center point). In simple words, it is an attack through which an attacker can exploit that system which belongs to the different.
The RDP client makes no effort to validate the identity of the server when setting up encryption. An attacker with the ability to intercept traffic from the RDP server can establish encryption with the client and server without being detected. A MiTM attack of this nature would allow the attacker to obtain any sensitive information transmitted, including authentication credentials While a powerful administration tool, RDP becomes a powerful attack tool in criminal hands. Criminals can use the same remote access tool to control the targeted system, and from there, move through the rest of the network. Potential malicious activities include credentials harvesting, account takeover, spam delivery, installing malware such as keyloggers and backdoors, and cryptocurrency mining An RDP attack takes place when an unauthorized person or entity is accessing a network through the device's RDP ports. The attack may be an actual person using brute force to hack into the RDP port, or it could be an automated technology, also using brute force to access the RDP port. Brute force is a term used when someone, or something, is guessing user credentials over and over again. In a real attack, we'd need to have the RDP client connect to our system instead of the target server. This could be achieved using ARP spoofing, DNS spoofing or some other method. Rather than cloud the demonstration with such details, we'll assume this is step is possible and just type the IP address of the attacker system into the victim RDP client
