Where does Nullbyte Ransomware come from?

Ransomware threats seem to be blooming these days. Therefore, it could be essential for you to know how such an infection can show up on your computer unnoticed and do such damage, even if in this particular case you may be able to recover your files without paying the ransom fee. One of the most likely ways for you to let this threat onto your operating system is through downloading a misleading attachment from a spam e-mail. Nowadays schemers use all kinds of eye-catching tricks, including fake e-mail addresses and important-looking subject lines, in order to fool spam filters and computer users as well. Even if you think that you would never open a spam mail or that you could not be tricked, it is still possible. The crooks behind such attacks can come up with any relevant-looking topic that would definitely make you want to check out the fake message and its attached file. This file can look like a normal image or text file. But it is indeed an executable file that either initiates the ransomware itself or downloads it in the background. The subject of such a mail can be anything in connection with your credit card, bank account, flight booking, Internet provider, or any unsettled or problematic invoice. The most important for you to know about these spam e-mails is that if you download and run the attached file, you may see a fake invoice or any other made-up document; but, at the same time, you will definitely activate this threat in the background silently. This means that removing Nullbyte Ransomware from your system will not stop the process of encryption because it will be most likely finished by the time you realize its presence.

In the case of this particular ransomware there is another source that is spreading it. By using, or rather misusing, the current craze of PokemonGo, Nullbyte Ransomware is distributed through suspicious file-sharing websites that host a cheat program for Pokemon hunters called “Necrobot.” So if you are also infected with this vibe and happened to download this program, there is a good chance that you have infected your computer with this ransomware this way.

How does Nullbyte Ransomware work?

This infection uses the AES (Advanced Encryption Standard) algorithm, which is built in your Windows operating system. For this reason, this ransomware can encrypt the targeted files in mere seconds really. This does not give you too much time window to act even if you have noticed some changes or the inability to open certain files. All your documents, pictures, and videos get a “_nullbyte” extension after the encryption and you will not be able to open or view them anymore even if you modify the file names. Once the damage is done, a ransom note window appears on top of all the open windows on your desktop and it also stays on top. This note tells you that you have to transfer 0.1 BTC, which is around 63 USD, to the given Bitcoin wallet address. After the criminals check if your transfer is really there, you are supposed to get the decryption key necessary for restoring your files. However, you should not even consider paying these criminals for a second because there is already a free tool that you can download and use to decrypt your files with. Of course, if you are not an experienced user, you had better ask a friend or a professional to do this for you. All in all, you should not make a step before you remove Nullbyte Ransomware from your PC because this is the only way for you to secure your computer. This is also true for those who are wise enough to keep a backup on a removable drive.

How can I delete Nullbyte Ransomware?

Fortunately, it is really a no-brainer to stop this threat because it does not lock the screen even if the ransom note window seems to block it. In fact, you can grab this window and move it out of the way. Although this infection does block the Task Manager and the Command Window, you do not need any of these to take action and remove Nullbyte Ransomware. What you need is the File Explorer and remember where you saved the executable malicious file. Please follow our instructions below this article if you need help with these steps. It is possible that this attack serves as a good lesson for you and you will be more alert when it comes to opening e-mails or downloading files. However, if you are interested in our opinion, we would say that the best way for you to make sure that your computer is clean and safe for you to use is to install a reliable anti-malware program.
