The ever evolving threat of computer viruses recently reached frightening new levels with the release of the Cryptolocker in 2013. This strain of virus is called ransomware because it holds your data hostage. While there have been previous examples of ransomware – none of them have seen as widespread infection as the Cryptolocker. Security specialists must constantly adapt to new threats; however, the attackers have the advantage of being several steps ahead. This means that despite best efforts of the good guys, some computers must get infected before the cure can be added to virus signature databases. While CryptoWall 3.0 is the most recent version, more will follow.

The program operates in secret and encrypts all files on the computer one by one. Once all of your data is encrypted, an intrusive pop-up window appears to inform you that you must convert $500 USD to the digital currency bitcoin in order to retrieve the key that will decrypt your files. The nature of data encryption means that a brute force attempt to guess this key will not be possible. Without taking proactive measures, there is no guarantee that your data can be restored – even if you pay the ransom. The success rate for a business that loses their data in any situation is very low, having a comprehensive back up plan is a requirement. Concise is ready to help provide protection for your data!
