Researchers have discovered a new variant of a particular ransomware which now specifically aimed at Dutch Internet users. It involves CTB Locker, which stands for Curve Tor Bitcoin, which for the first time in mid-July appeared and encrypts files for ransom.
CTB Locker, called Microsoft Critroni, stands out because of the methodology used. Thus, the ransomware uses the Tor network to communicate with infected computers. Instead of the file to use Tor.exe, as is done by other malware, the maker of CTB Locker has the code of Tor made part of the ransomware code.

Where ransomware also strikes a different path to the encryption used. Most ransomware uses a combination of AES and RSA encryption to encrypt the files of victims. CTB-Locker uses an asymmetric cryptographic protocol known as ECDH (Elliptic Curve Diffie-Hellman). Another new development for the first time at the CoinVault-ransomware was seen is the free decrypt files. Let CoinVault victims one file free decrypt, CTB Locker decrypts free five files.
