What is NOT_OPEN LOCKER?

NOT_OPEN LOCKER is a ransomware-type, high-risk virus that was discovered by Jakub Kroustek. This virus is a new variant of Everbe ransomware that stealthily infiltrates systems and encrypts all files. During encryption, NOT_OPEN LOCKER adds the ".[notopen@countermail.com].NOT_OPEN" extension to every affected/encrypted file.

For example, a file named "1.jpg" will become "1.jpg.[notopen@countermail.com].NOT_OPEN", and so on. Once NOT_OPEN LOCKER ransomware has encrypted files, it stores a "!_HOW_RECOVERY_FILES_!.txt" file in every folder that contains encrypted files.
