It was however unfortunate that paying the ransom did not always guarantee that the files were decrypted. The people who were responsible for this malware did not always assure the victims that they were going to decrypt the files (McMillan). CryptoLocker was isolated in June 2014 through an operation known as Operation Tovar. This operation enabled the security firm to obtain the database of private keys that were used by the CryptoLocker and used an online platform for victims that were affected to obtain the private keys.
