Codnat ransomware is the cryptovirus that comes with .codnat and .codnat1 file markers into the DJVU ransomware family

 Codnat ransomware

Codnat ransomware – the virus that is based on money extortion purposes because virus developers are cybercriminals. Unfortunately, users' files get locked and even damaged due to this threat and sometimes this attack leads to permanently lost data or money since malware creators are focusing on getting profit. Also, Djvu ransomware developers releasing new versions all the time and targetting people all over the world.

The encryption process is the first thing that Codnat ransomware virus performs on the infected system after the infiltration.[1] When many files get locked and marked with .codnat extension, ransom note gets delivered on the text file _readme.txt which contains contact information and the amount of ransom. $980 is the initial amount that criminals want from the victim, but it can go to $490 if the person writes virus developers in the first 72 hours. However, paying the ransom is not the best solution, especially when the decryption of files encrypted by Codnat ransomware is possible with the STOP ransomware tool.

Although Codnat ransomware virus offers a discount in this ransom note, you shouldn't trust that statement and keep out of contact with cybercriminals in general. There is no need to write to them because paying the ransom is not going to guarantee the file recovery and virus developers can even demand more money.

Remove Codnat ransomware as soon as possible and avoid communication with those people. Then you can rely on your file backups stored on the external device or use data restoring software that helps with encrypted files. Just make sure to delete all traces of this malware to ensure that your restored files are safe.

Employ Reimage or a similar antivirus program for automatic Codnat ransomware removal and scan the system thoroughly. Then you need to follow the results of that malware check and eliminate all intruders or virus damage from the computer. 

Codnat ransomware virus
Codnat ransomware is the cryptovirus that encrypts personal documents and images found on the victim's computer to demand payment for recovery.

Since Codnat ransomware infiltrates the system silently, you cannot notice the initial infection and know exactly when this threat came to the system. During the time on the machine, the virus affects more vital parts of the system to ensure its persistence. These alterations involve adding system files, applications, and registry entries or even disabling some functions.

Codnat ransomware as other versions of the same Djvu virus disable security functions, antivirus tools or features and this way keeps running on the system for longer. You can enter the Safe Mode with Networking and remove the threat with your anti-malware program without interruption.

Malicious files from the email attachment deliver payload carriers

When files replicate legitimate financial documents sent from well-known companies or services, people tend to open them without thinking about possible danger and malware infiltration possibility. However, there is not much needed. When the document is downloaded on the system and opened, macro viruses get triggered and malicious script launched.

Ransomware can also come with the help of trojans, malware, and exploit kits. Experts[3] note that patching vulnerabilities is especially important, so don't leave any security flaws if you notice any. You should open legitimate emails only and don't rush to read the email you received without expecting.
