We have seen a series of Ransomware tended to be simple with dogged determinations to extort money from victims. But with the exponential rise in the samples of Ransomware last year, we saw more subtle in design, including "Cryptolocker" that was taken down along with the "Gameover ZeuS" botnet last June. As a result, another improved ransomware packages have sprung up to replace it — CryptoWall.

 

Ransomware is an emerging threat in the evolution of cybercriminals techniques to part you from your money. Typically, the malicious software either lock victim’s computer system or encrypt the documents and files on it, in order to extort money from the victims. Since last year, criminals have generated an estimated US$1 million profits.

 

Now, the infamous Cryptowall ransomware is back with the newest and improved version of the file-encrypting ransomware program, which has been spotted compromising victims by researchers early this week, security researchers warned.

 

The new version, dubbed Cryptowall 3.0 (or Crowti), uses Tor and I2P (Invisible Internet Project) anonymity networks to carry out communication between victims and controllers keeping it away from researchers and law enforcement officials.
