A new ransomware called CoinVault has been released

(via Bleeping Computer)

Another particularly nasty virus that blackmails you for your own files:

CoinVault is a new ransomware from the same family as CryptoGraphic Locker. Once infected, CoinVault will encrypt all of your data files and then demand a .7 bitcoin ransom to decrypt your files. If you do not pay the ransom within 24 hours, the ransom price will increase.

When you become infected with CoinVault it will configure itself to start automatically when you login to Windows by setting an autostart in the Registry called Vault. The application will then scan your drives for data files and encrypt any that are detected. It will store the path to each file it encrypts in the %Temp%\CoinVaultFileList.txt file.
