On Christmas Eve, cybercriminals targeted three hospitals in Germany using Lockbit 3.0 ransomware. Ransomware is a type of malicious software that infects computers and networks. It holds data and other sensitive information “hostage” in exchange for payment. If you refuse to meet their payment demands, the cybercriminals could destroy the files. Or they could make them available to the public, resulting in data theft and leaks of sensitive information.
