What is LeChiffre Ransomware

Translated as Cipher in French, LeChiffre is a relatively old ransomware-type virus discovered in 2015. Unlike other programs, it encrypts user’s data by using Blowfish algorithms (instead of AES). After penetration, LeChiffre does a pure classic, it scans your disk for available files (like images, documents, etc.) stored on the system and encrypts them by changing extensions to .lechiffre. For example, the original 1.mp4 will be transformed into 1.mp4.lechiffre. Newer variations also add a random alphanumerical sequence to this suffix. Thereafter, the program creates an HTML file (_How to decrypt LeChiffre files.html) that is automatically opened in a browser or text file (_LeChiffre_BACKUPVO.txt).

How LeChiffre Ransomware infected your computer

Ransomware is typically installed via e-mail spams, trojans, and other channels, however, LeChiffre is an exception. Developers infect the virus manually by remotely hacking desktops through unprotected connections. After the server is hacked, scammers run the LeChiffre.exe executable file to encrypt the data. Once the LeChiffre.exe is opened, users can see a tab with lots of options such as “Start”, “Pause” and others. Unfortunately, hackers control the system and disable any attempts from users to prevent the process. Once finished, hackers will exit the system and clear up all of the traces. Be careful and attentive whilst surfing the web, visit only legitimate and trustworthy pages that use protected networks. Evade clicking on ads because they can redirect you to malicious pages that can exploit poor network configuration and let swindlers invade your PC. To get rid of LeChiffre.exe and decrypt your data, follow the instructions listed below.
