This article is created with instructions to aid you to remove CryptoMix ransomware and try to restore .lesli encrypted files.

A ransomware virus, believed to be part of the CryptoMix malware family is believed to cause some infections and encrypt the files of the infected computers, asking ransom money in a text, named “INSTRUCTION RESTORE FILE.TXT”. In those instructions, the approximate sum of 0.5 to 1.5 BTC may be requested from the victims to pay to get a decryptor for the encoded files. In case you have become a victim of the .lesli virus, we advise you not to perform any payment or communication with the cyber-criminals and instead to focus on removing the malware and encrypting files encoded by this malware by yourself.

How .lesli CryptoMix Ransomware Infects

For it to cause a successful infection, the criminals behind CryptoMix .lesli threat might perform several different actions. One of those is to obfuscate a malicious code or file and disguise it as a legitimate file for the file to fool an inexperienced user into opening it. This is achievable via the usage of socially engineered phishing e-mails containing fraudulent information, like the victim’s need to check his bank account balance sheet, for example. Opening the attachment results in the activating of a malicious script without Windows Firewall or any other defensive software detecting it (in most cases). After this is done, the virus begins to drop malicious files with different names in several Windows folders that contain different names:

After the encryption process has been completed, the virus may add a file extension that contains an e-mail address and the .lesli suffix. Files encrypted by .lesli may appear like the following:

As soon as this has been completed, the .lesli virus may drop a .txt file, named “INSTRUCTION RESTORE FILE.TXT” that aims to notify the user of the situation and provide instructions on decrypting the files by paying a hefty ransom fee, which is highly inadvisable by malware researchers.
