Another group has made a copycat of CryptoLocker, and they've gone so far as to even use the CryptoLocker name. Although recently some users are now seeing the infection as TorrentLocker, perhaps the original creators of CryptoLocker are feeling territorial about use of their name. Beyond stealing the name and being a ransomware infection, these two infections are not the same.
This new CryptoLocker works to encrypt all of your data and renames the files with a .encrypted file extension; although this version does not delete shadow volume copies which in some cases can be used to recover files. You then receive a ransom note, so to speak, giving you a link to purchase the decryption key for your files. The cost for the decryption key is 1.8 Bitcoins and interestingly is posted as AUD, Australian currency. 1.8 Bitcoins may seem like an odd amount, but at the time of this CryptoLocker's release it was equal to 1,000 AUD.
