Ransomware, created mainly for Russian speaking users, named KawaiiLocker has been reported to increasingly infect more and more users. The virus locks the files of the infected computer by encrypting them and asks the victim to pay approximately 6000 rubles (approximately 100$) to the criminals in order for them to restore access to his encrypted files. The files are then kept in a list, called crypt_list. It does not add any file extensions to the encrypted files or changes their names. Everyone who has had their files encrypted by KawaiiLocker, are strongly advised not to pay the decryption price and see alternative methods like the ones in this article to remove KawaiiLocker and restore the encrypted files.
