Brute Force Attack in Remote Desktop Connection Cure


what to do if a brute force attack in remote desktop connection happens? 


Preventing a Brute Force Attack in Remote Desktop Connection 

A brute force attack in remote desktop connection is one of the easiest and cheapest ways to get access to your network. Brute-force attacks are carried out by hackers who try to crack a password by simply trying out different combinations of characters in quick succession. The algorithm is very simple and is limited to trying out as many character combinations as possible, which is why the term "exhaustive search" is used. The attacker normally uses a high-performance computer that performs a large number of calculations per second and can therefore test a large number of combinations in a very short time.

The method is often used successfully in practice, since many users use short passwords, which moreover often only consist of characters from the alphabet, which drastically reduces the number of possible combinations and makes a brute force attack in remote desktop connection easier.

The Process of a Brute Force Attack

The process of a brute force attack in remtoe desktop connection or in fact any other system is fairly easy. Imagine a burglar trying to break a safe’s combination, but the burglar has no idea what the safe’s combination is. He starts trying every possible combination that exists from a list of common safe combinations. If one of the safe combinations opens the safe the attack has been successful. Replace the safe combination with a password and the safe with your account and you see how a brute force attack works.

Passwords are usually not stored in plain text on the systems, but as hash values. Since the password cannot be calculated backwards from the hash value, the brute force method determines the hash values belonging to the randomly selected passwords until a hash value matches the stored hash value. When the algorithm has calculated a hash value that matches the hash value stored in the compromised system, the password has been found.

Lists with hash values of frequently used passwords are often used. These are called rainbow tables or “dictionaries” (hence the term dictionary attack is sometimes used for brute force attacks).


How Fast Can Your Passwords be Cracked

The RC5-72 project by shows how quickly passwords can be decrypted. The aim of the project is to decrypt a message that was encrypted with a 72-bit key. All possible keys are tried out until the right key is found. Since several users make their computer capacities available in this project, over 800 billion keys per second can currently be generated (as of May 8, 2012). In older projects from this organization, a 56-bit key was cracked within 250 days and a 64-bit key within 1,757 days.


Brute Force Attack on RDP Connection Consequences

After your password gets cracker, hackers are free to do whatever they want with your account. Here is why you should be worried about a brute force attack in remote desktop connection s. There are a few ways that hacker can explit access to your account.



Don’t think if hackers got your computer, you will know about it. Most of the time they will wait and try and collect data on your computer for months or even years. The more they have on you the more they can exploit you for it. One of the best ways to collect data on your computer is to install a key-logger. Key-loggers are software that will collect everything that you type in your keyboard without you knowing about it. With this approach they can collect your passowds, security infromation and bank accounts easily.


Installing Ransomware

Ransomware are software that will encrypt the data on your computer or phone until you pay a fee (or ransom) to the hackers so they will send you the password to get your access back. After a brute force attacke in remote desktop connection is successful the hackers can install a ransomware on your pc and demand outrageous amounts of money to give you your account back. You have two options here, either pay the ransom or forget about the data you have stored on your PC.

As Alfred says in the movie Batman:The Dark Knight, “Some people only want to watch the world burn”. Some hackers behave the exact way as the joker, they hack you so they can have fun disturbing what you do daily on your computes. They can make your experience working with the remote desktop connection a living hell. It also affects Performance in your remote desktop clients, because they can just keep on overloading your system and network with useless processes to limit your processing power and bandwith and in turn stop you from accessing your resources.


Brute force attack on encrypted data and possible protective measures


The brute force method can be used to attack encrypted data. Here too, randomly selected keys are tried until a match can be found. The length of the key used is decisive for the chances of success of the attack. Modern encryption algorithms use key lengths of, for example, 128 or 256 bits, in which the computational effort to find the key is too great in terms of time and costs.

The computational effort increases exponentially with the key length. When using the computing power available today, especially long keys take times of several thousand years to find the right combination. However, as the computing power of the systems continues to increase as a result of technological progress, it cannot be ruled out that encryption, which is believed to be secure today, can be decrypted using the brute force method in the future.

A possible protective measure is the selection of long passwords with numbers, special characters and upper / lower case without reference to existing words. As the complexity of the password increases, the number of computing operations required for the brute force attack increases. Brute-force attacks on login screens are made more difficult by limiting unsuccessful password entries.but in windows rdp there are not many precautions that you can take, so you have to try third-party software.

Just Get a Firewall

Even after you try all of the options above you might be at risk for getting your remote desktop connection hacked. Here is where SUNFIREWALL comes in. with the brute force attack in remote desktop connection prevention method, it can prevent hackers from accessing the ports that use remote desktop protocol. It also can identify possible bruce force attacks and trace the hacker’s location and information. But that’s not all, Sun Firewall has a feature-rich pallete of services that you can check out yourself.
