CryptoNar Ransomware

CryptoNar Ransomware is a malicious application that marks its damaged data with .partially.cryptoNar or .fully.cryptoNar extensions. If you see these extensions at the end of your files’ names, you should keep reading this text to find out more about this threat. Further, in the article, we will explain how the infection might have entered your device, how it works, and what can be done to avoid it. Also, we will discuss the options victims have after coming across it. Truth to be told, our researchers believe the best way to deal with CryptoNar Ransomware is to get rid of it at once. Keeping the malware might be dangerous because it can auto start with the system. Keep it in mind if you decide to eliminate the threat you could use the instructions we will place at the end of this page.

A lot of similar malicious applications are distributed via Spam emails. This time our researchers learned, the CryptoNar Ransomware’s creators made its launcher look like a PDF file. In other words, victims who do not sense anything suspicious could accidentally install the malicious application without realizing it. Obviously, what we would suggest for protecting the system against such malware is scanning all files from unknown senders or received for unknown purpose with a reliable antimalware tool. On the other hand, if you know, you were not supposed to get the suspicious file you could simply forget your curiosity and erase the email it came with.

Our specialists who tested CryptoNar Ransomware claim it is very similar to CryptoJoker Ransomware and could have been developed by the same cybercriminals. It seems the same as the mentioned threat; it should be able to encrypt different file types. However, it would seem the infection can lock data only in the %USERPROFILE% directory. Plus, it cannot harm data belonging to the computer’s operating system. As said earlier all encrypted files are supposed to be marked with a specific additional extension. Also, the moment all targeted data is affected the malicious application should drop a text document named CRYPTONAR RECOVERY INFORMATION.txt on the user’s Desktop. The message inside of it might appear on the infection’s window that should be displayed after the encryption process as well.

The mentioned text file (CRYPTONAR RECOVERY INFORMATION.txt) and the malware’s window may show the same message which is supposed to demand users to pay around 200 US dollars in Bitcoins. The text claims the data was locked while using a robust encryption algorithm known as RSA-2048 and it can be decrypted only with a unique decryption key and a decryption tool created by the hackers. The bad news is this unique key said to be stored on a private server; is supposed to be erased after 72 hours. No doubt, the CryptoNar Ransomware’s are giving a specific amount of time to pay to make the user rush.

Needless to say, we would not rush paying the ransom; in fact, we do not recommend paying it at all. The hackers can promise anything or even prove they have the means for decryption, but there is not knowing whether they will bother to deliver them. Meaning, there is a chance they could refuse to help the victim even if he did pay. It seems to us the best way to recover data is to use backup copies, although given CryptoNar Ransomware can affect files located only in %USERPROFILE% directory it is possible the victim might not lose any important data if he does not keep it in this location. In which case, we advise removing the malware with no hesitation.
