L' INTELLIGENCE CYBER par Jean-Paul Pinte

Crypto ransomware is a growing threat against Internet users and even users on corporate networks. Attackers infected a system in order to encrypt all available files locally and remotely for the user. When the files are encrypted (and very often with advanced encryption techniques), the attackers try to extort the users via a ransom to recover the encrypted files. Such ransom attacks can be very successful especially in corporate networks where file servers (NAS, CIFS servers) are extensively used.
