    Beware – ransomware is still out there! CryptoLocker, CryptoWall and CryptoVirus

    Beware - ensure you have safeguards on your computerDo you regularly back up your data? We hope so, because there are some nasty viruses out there, finding new and innovative ways to encrypt your data. If you don’t back up your data then a vicious virus may put a halt to your business.

    CryptoLocker was, and still is, a ransomware Trojan. It targets computers running Microsoft Windows and infiltrates itself via infected email attachments or existing botnet. As soon as it is in, it works its way through your documents encrypting files so that you will be unable to open them.

    Can CrytoLocker be removed?
    Yes

    What about my encrypted files?
    This is altogether trickier. When you try to open your files, a message will appear asking you to pay via Bitcoin or a pre-paid cash voucher by a stated deadline. It threatens to delete the private key (that is the only way to decrypt your files) if the deadline and payment requests are not met. Some companies paid the ransom, others did not and were unable to access their files.

     What has happened since last year?
    CryptoLocker has been isolated and the security company involved in this process managed to access the private keys and set up an online tool for recovering files without paying the ransom.

    How much money was extorted?
    It is estimated that the group behind CryptoLocker received $3 million.

    Are there other ‘nasties’ out there?
    Yes – CryptoLocker may have been isolated and a way found to decrypt files for free, but CryptoWall and CryptoVirus are both alive and kicking and cutting a swathe through computers the world over.
