Emsisoft Decrypter for LeChiffre

Emsisoft Decrypter for LeChiffre is a lightweight tool designed to help you find the master decryption key and hence, unlock files that have been hijacked by LeChiffre ransomware.

Signs of an infection with LeChiffre ransomware

Unlike the vast majority of ransomware,  LeChiffre infiltrates computers with the help of a manually-hacker server. Moreover, you should know that it is remotely executed by the hacker and encrypts all available network and local sources in an operating system via the Blowfish algorithm.
What this means is that the encryption of the files is based on your system's parameters and therefore, you are required to perform the decryption on the same system and the same user profile. The preferred victims are companies, whereas the ransom is around 1 Bitcoin per computer. You can recognize an infection based on the extensions of the files – LeChiffre – along with the ransom note.

It can help you find the decryption key

First off, you should know that the tool requires Internet access so that it can perform the same query as the malware and retrieve the ISO code of the country you are living in. Therefore, you should keep in mind that you might have to give permissions in the firewall for the non-encrypted connection.
The decryptor comes with an intuitive interface, so it is unlikely that you can encounter any issues. Therefore, after you specify the location of the infected files, you can hit the Decrypt button and then preview the success of the operation in real time from the Results tab.
It is worth mentioning that since there are no guarantees that the automatically generated key is the correct one, it is advisable to keep the encrypted files until you double check.

A useful utility that can help you recover LeChiffre infected files   

In the unfortunate event that you find yourself of finding a note specifying that your files and data locked, then it might be very tempting to pay the ransom and get this nightmare over it. However, since there are no assurances that you are going to receive the correct decryption key, using a specialized tool, such as Emsisoft Decrypter for LeChiffre, might be an alternative to account for.
