Ransomware is a form of malware designed to encrypt files on a device to render them unusable until a ransom is paid for a decryption key. Ransom DDoS attacks involve overwhelming public servers with large volumes of traffic to bring them offline until a ransom is paid.
Several recent ransomware attacks have made headlines, including attacks on JBS (a global meat processor), Colonial Pipeline (a top US fuel pipeline), CNA financial (a large US insurance company), and Bose (an audio electronics manufacturer).
Administrators are urged to review ransomware guidance, follow best practices for preventing ransomware attacks, ensure that data is backed up regularly, and create a continuity plan to follow in case a ransomware attack occurs.
