As the global pandemic continues, most of us are accustomed to work-from-home culture. This change in working conditions has made remote desktop applications and VPNs the go-to ways to access enterprise resources inside the corporate network.
Remote Desktop Protocol (RDP) facilitates remote access to Windows machines. To access a machine remotely, a user must be connected to the network the machine is in. The port that is commonly used for RDP connection is 3389. Other ports can also be configured to invoke RDP.
Unfortunately, with the increased use of RDP comes higher risks. Even simple brute-force attacks are fairly successful at hacking into RDP-enabled machines.
If an RDP attack is successful, the hacker will have access to all the resources in the affected machine. They can also block the screen with a fullscreen image, encrypt important files, and demand a ransom to allow the legitimate user to access the machine and its files. The malware that facilitates these steps is called ransomware. In 2019, an estimated 63.5 percent of ransomware infections were through RDP attacks.
During an RDP attack, other malware can be installed and allowed to spread through the network from the hacked machine. Company data can be stolen or tampered with. The possibilities are infinite. Hackers utilizing RDP attacks get huge returns with little effort.
With the help of network scanners like Masscan, hackers can find the TCP and IP port ranges that are used in RDP servers in a matter of minutes. Then the hacker can track one of them down and try to gain access to the machine using brute-force tools, which automatically try a massive number of username and password combinations within a small time interval. The quickest match can be made within two minutes, but on average, the right username-password match is found in a day or two.
