Several high-performance computers (HPCs) and data centers used for research projects have been shut down this week across Europe due to security incidents. About a dozen of these supercomputers are affected in Germany, U.K., and Switzerland, leaving researchers unable to continue their work. A total of seven attacks were detected, the first one on January 9. The European Grid Infrastructure (EGI) in an advisory published details about two cyber attacks hitting academic data centers that appear to be the work of the same actor.
