There are many security risks to worry about when managing or using a business network. However, one of the biggest threats to a business’ network is CryptoLocker.
What Is Ransomware?
In order to discuss CryptoLocker, first we must have a handle on ransomware. Ransomware is a type of malware that infects computer systems, restricting users’ access to the infected systems. Ransomware variants, such as CryptoLocker, extort money from victims by displaying an on-screen alert stating that the user’s systems have been locked or files have been encrypted.
