KCTF Locker Ransomware is a rather odd ransomware infection because it doesn’t work like most of them. It doesn’t spread in the wild, so if you have this on your computer, it is very likely that someone infected you individually. You can remove KCTF Locker Ransomware by following the removal instructions below this description, but you should also pay more attention to your computer’s security in general if you want to avoid similar intruders in the future. Your system’s safety should be one of your top priorities, and you definitely should not compromise on that.

Now, why do we say that KCTF Locker Ransomware is a rather weird infection? That’s because this program was created as a challenge for a Capture the Flag (CTF) competition. It means that this program may not even work properly, but its code could be used by third parties to make certain improvements in the future. In other words, it wouldn’t be surprising if we were to come across another ransomware infection based on the same code. So, rather than a dangerous intruder, KCTF Locker Ransomware works more like a wake-up call that tells you that you have to invest in cybersecurity.

As far as the composition of this infection is concerned, KCTF Locker Ransomware is coded in the .NET programming language, and it should be using the XOR encryption algorithm to lock up the target files. As we all know, ransomware infections encrypt user’s personal files and then demand a random fee to be paid. This program, in particular, scans the target computer for the DWG file extension. These types of files are used by CAD programs. Seeing how specific KCTF Locker Ransomware is, it is possible to assume that this program targets one specific system.

Also, when we run KCTF Locker Ransomware on our test bed, this program doesn’t encrypt anything because it doesn’t have the permission to access the files. So it only supports the notion that KCTF Locker Ransomware might work only on one particular system, and it can be used to infect users individually.

On the other hand, if this program does infect you, it exhibits symptoms similar to all the other ransomware programs. For example, it shows a warning message that says the following:

This is program is written as a part of CTF task. But it can be harmful for your computer. Choose Cancel to exit. If you are OK, press OK.

Seemingly, it gives you the option to choose whether you want this program to proceed or not. Now, if it’s only the test run, it might not be a problem, but if KCTF Locker Ransomware gets exploited by cyber criminals, it could really turn into something terrible.

Therefore, you shouldn’t tolerate it. What’s more, the program may even display another message that tells you that you have to transfer 10 BTC for the decryption key, but it doesn’t offer any specific information. Not to mention that 10 BTC is an insane amount of money, and no one in their right mind would ever consider paying this much.

Simply remove KCTF Locker Ransomware from your computer by closing the messages and deleting the file that launched the infection. If you are not sure which file is responsible for running this program, you can scan your computer with a security tool that will locate every single treacherous file currently on your computer.

Afterwards, do not hesitate to invest in a licensed security tool that would protect your PC from various threats. You should also educate yourself about ransomware infections and back-up your files, just in case you might encounter a similar intruder in the future.
