Crypto-ransomware variants have enterprises on edge because of the threat of irreversibly damaged files. Some organizations, including most recently the Tewksbury, Ma., police department have gone as far as to pay hundreds of dollars in
ransom for the recovery key.
Some technology companies are beginning to fight back with tools that decrypt potentially lost data. Kaspersky Lab, in cooperation with the National High Tech Crime Unit of the Netherlands and the Netherlands National Prosecutors Office, recently made available tool that helps recover files lost to the
CoinVault ransomware. As of April 17, there were more than 700 decryption keys available in the database of the decryption application.
