Cybercriminal these programs continue to spread, even if they have been in use for a long time.
During the second quarter of 2013, McAfee had counted a record 320,000 new samples for this type of malware. Early September, we had then seen the use of cryptolocker, a Trojan that spreads via infected e-mails, mostly in Anglo-Saxon countries. This was camouflaged in UPS / FedEx or bank bills messages. Once installed, it is raised by a 2048 bit RSA key, stored on pirate servers of personal data.
The user then receives a request to transfer the amount of Bitcoin equivalent to about $ 300
According to Dell SecureWorks, cryptolocker infected between 0,000 and 250,000 computers within three months. This would have allowed cybercriminals to retrieve the tidy sum of $ 700,000.

Back up your data regularly. Although malware encrypts your personal data, this way you can still recover. Refuse to pay the ransom, because there is no guarantee that cybercriminals did you transfer the key to decrypt your data. Do not open emails from people you do not know.
The best solution is to use a VPN. Thank you to a VPN service, your IP address is hidden and can not be identified. When you connect to the Internet via an unsecured connection through the VPN, you get strong encryption, which will not allow anyone to know which sites you visited. And your Internet connection is secure wherever you are. A special VPN also allows you to protect your connections from your smartphone or tablet.
