Lumen Technologies, a leading provider of telecommunications services, identified two cybersecurity issues, including a ransomware attack. One of the events involved a ransomware attack on a small number of its servers that operate a segmented hosting service. The corporation simply acknowledged that the issue "is currently impairing the operations of a small number of the Company's enterprise customers." It gave no further information regarding the family of ransomware that infected its systems. Lumen developed improved security software following the ransomware attack's detection, which enabled the business to identify a different incursion.
