The ransomware

A ransomware is a malicious software that takes personal data hostage. He encrypts personal data and asks the owner for money in exchange for the decryption key.

A ransomware typically spreads in the same way as a Trojan Horse: it penetrates the system for example via Web Exploit or through email-malicious campaigns. In any case, a ransomware will try to extort money from the user, by having him buy a program to decrypt his files.

The means of fight recommended against a crypto-locker are the following:

  • Disconnect infected devices from shared networks, wired or wireless.
  • Change your passwords after cleaning the network.
  • Make regular backups of his data, and store them offline.
  • Consult a computer security expert for instructions.
