Files encoded by this ransomware remain inaccessible until they are decrypted by a special tool that reverts their code back to normal. Files encrypted by the Blue Locker virus can be recognized by the malicious extension .blue appended to their original names. The encryption process which is dealt with the help of two cypher algorithms – AES and RSA, prevents victims from using files marked with the .blue extension.
