Lesli – RansomwareThe Lesli stands for a ransomware-type infection. The virus comes from the CryptoMix ransomware family. Lesli was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Lesli adds the “.Lesli” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Lesli, will be renamed into “myphoto.jpg.Lesli“. As quickly as the encryption is finished, Lesli places a special text file into every folder containing the encrypted data.
The message given by Lesli text file requesting for the ransom is definitely the like the statements given by other ransomware representatives belonging to the CryptoMix clan. It actually mentions that the information is encrypted which the only way to restore it is to use a a distinct decryption key. Sadly, this is absolutely true. The type of cryptography mechanism applied by Lesli is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is completely distinct. It is difficult to bring back the files without the key available.
Another technique of Lesli is that the victims cannot access to the key. The key is kept on a specific server run by the frauds associated with Lesli ransomware. To get the key and recover the important information people need to pay the ransom.
Nevertheless, irrespective of the requested amount, people must stay away from paying the ransom virus. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets.
