Cryptoshocker, carrying a name familiar to the notoroious Cryptolocker has recently started causing problems more and more often. The .locked file extension is added and an extremely powerful encryption cipher has been used to encode users’ files. Infected users are extorted to pay the hefty sum of 200 dollars in BitCoins to the cyber-crimials. This is done by using anonymous Tor networking communication. Everyone infected should not pay any ransom and wait for a decryptor to be released by malware researchers in the near future (we will post a web link here if it has been created).
In the meantime it is strongly advised to remove the ransomware and try alternative methods for file restoration, like the ones in this article.
