How to Delete LeChiffre ransomware from PC
LeChiffre ransomware is a data-encrypting malware that first came in notice when it attacked three banks and a pharma company in Mumbai (India) in 2016.

Every file that affected automatically adds a suffix namely .LeChiffre and a ransom note namely _How to decrypt LeChiffre files.html is added that contains instructions regarding the ransom payment and communication channels with the developers.
The ransom note triggered by LeChiffre ransomware says that your file has been locked by a powerful RSA 1024 and AES encryption cipher and the encrypted files can only be accessed using the decryption key. [email protected] email ID is provided as the address to communicate with the associated developer. The exact amount of ransom money is not mentioned in the note however in many Online tech forums, the victim have revealed that LeChiffre ransomware demands to pay 1 Bitcoin which is around $4000 in precise.
The ransom note provided by this malware is unusual as it doesn’t contain much information. They it offers to send 1-2 encrypted files to the provided email ID in order to get it decrypted for free. The file should not be more than 5 MB of size and must not contain any important details such as username, login-details, backup files and so on. This is a spam and trick to convince you that the provided decryption tool really works however it doesn’t. And most of all, the victims doesn’t receive the decryption tool even after payment and their money and time goes in wastage. Thankfully, the “Emsisoft” researchers have developed a free decryption tool that you can easily download from its official websites or forum.

“Your important files (photos, videos, documents, archives, databases, dackups, etc.) which were crypted with the strongest military cipher RSA1024 and AES. No one can’t help you to restore files without our decoder. Photorec, RannohDecryptor, etc repair tools are useless and can destroy your files irreversibly. If you want to restore files – send e-mail to decrypt.my.files @ gmail.com with the file “_secret_code.txt” and 1-2 encrypted files less than 5MB as *.doc *xls *jpg but not database (*.900 *.001 etc).

They display ransom note in both .html as well as .txt format. Its payloads may appear like any other genuine executable file and it copies itself in the Trash section. It is up to the cyber-criminals to decide what type and how many files they want to encrypt.
In order to open the backdoor, it replaces the sethc.exe executable in the C:\Windows/system32\sethc.exe with cmd.exe. This way, the cyber-criminals can launch any specific command by gaining remote access to the machine without any login data. One more interesting fact is that this ransomware record some specific details about the PC including its geographical location, IP address, country code number, OS and so on. It uses a predetermined HTTP protocol to begin the remote communication and deliver sensitive information via a command and control server.
Should I Pay the Ransom Money?

The deadly ransomware like LeChiffre ransomware may delete the “Shadow Volume Copies” as well hence the last option is to use a data recovery tool. The recovery software offers a special feature to retrieve data that are damaged or encrypted by ransomware or any kind of malware infections.
How LeChiffre ransomware does Gets Distributed?
The associated developers use multiple channels to distribute this malware. The most popular of them are “Remote Desktop Ports” that has security vulnerabilities like bad password protection.
