What is KEY0004?
Nowadays, computers are the only way to remember old good days or to perform a job, due to the necessity of isolation. For hackers current situation is a great opportunity to get more money, because the most of humanity spends the time on the internet. So if you faced the fact, that your files have changed their extensions to “.KEY0004” ones, your computer is infected with KEY0004 ransomware. This virus is the new one and it doesn’t belong to any already known file encryption-ransomware family. In the most cases KEY0004 ransomware spreads by the means of various executable files, that can be found on numerous file sharing services and torrent trackers. Hackers also create special fishing web pages by the means of which they make victims to download and install this malicious program. The one more way of distributing it is the fake emails. Hackers often inject the code of the virus into a harmless file, and the code is executed once such a file is opened. It happens because of the various backdoors and bugs of the software and operating system. Once the virus gets into the system, it immediately begins to change files in the Registry and to modify various system processes. Then KEY0004 begins the scanning process. It looks for the files suitable for encryption. If the files were found, KEY0004 ransomware begins to modify their structures to make them unreadable. Then it drops the ransom note called “HOW_TO_RECOVERY_FILES.txt”. Such notes are used by hackers to make their victims pay for the decryption tool. Unfortunately, the surest way to decrypt your data is to get it from criminals, however, they usually deceive their victims. Sometimes they just ignore the victims once they’ve been paid and sometimes they send them more malicious malware instead of the tool. We strongly recommend you not to contact with them, otherwise everything can become much worse. In order to help you we’ve prepared the detailed guide on how to remove KEY0004 ransomware and decrypt “.KEY0004” files.
