What is Nesa Ransomware?
If you do not want to face malware, you need to secure your Windows operating system. If you do not take care of it, Nesa Ransomware is one of the threats you could face and, arguably, it is one of the worst infections you could face. That is because its main function is to encrypt your files, after which, you will not be able to read any of them. Which files are encrypted depends on what kinds of files they are and where they are stored. Unfortunately, the threat is likely to corrupt documents, pictures, and all other files that you consider to be personal and irreplaceable. Perhaps you have backups of your personal files? If they are stored outside of the infected machine (e.g., cloud storage), you should have no trouble replacing the corrupted files, but you should delete Nesa Ransomware and secure your operating system before you take care of that. If you need help with the removal and the protection, we’ve got you covered.
How does Nesa Ransomware work?
Nesa Ransomware belongs to the STOP Ransomware group, and it is identical to hundreds of other malicious file-encryptors, some of which include Meds Ransomware, Zatrov Ransomware, Vesrato Ransomware, or Cetori Ransomware. They usually enter Windows operating systems when victims are tricked into opening misleading spam email attachments or downloading malware, when remote access vulnerabilities exist, or if other malware is already active on the system. The entrance of these infections is silent, but once they are in, they encrypt files quickly, and then the “.nesa” extension is appended to their names. You cannot miss this. Also, the files become unreadable, which is another sign that they were encrypted. Finally, Nesa Ransomware presents “_readme.txt,” which carries the message from the malicious attackers. If you have not opened this file thinking that it is malicious, you have nothing to worry about. Of course, when it comes to malware, it is best not to open any files created by it. It is also important that you delete every single file that was created by the threat.
The message informs that files were encrypted, that a special “decrypt tool” is the only thing that can restore files, and that one file can be decrypted for free if the victim sends it along with an ID code to gorentos@bitmessage.ch or gerentoshelp@firemail.cc. You are also supposed to send a message if you decide that you want to pay the ransom requested in return for the decryptor. According to the ransom note, the tool costs $490, or $980 if the original sum is not paid within 72 hours. However, it is unclear how this money is supposed to be sent to the attackers. Most likely, they will ask you to send it in some kind of crypto-currency to a dedicated crypto wallet. Unfortunately, even if you follow the instructions to a tee, you might not get the decryptor in return. In fact, that is what is most likely to happen because the attackers have no reason to give you what you need. All they care about is money, and once their greed is satisfied, they can forget about you and your problems. Unfortunately, no one can force them to help you.
