Ukrainian hackers take out hundreds of Russian space research servers and supercomputers


The cyber warfare between Russia and Ukraine continues as hackers from the latter launch an attack and destroy the database and infrastructure of Russia’s Far Eastern Research Center of Space Hydrometeorology, “Planeta”.

According to Ukraine’s military intelligence agency, the attack resulted in two petabytes of data and 280 servers being destroyed. Additionally, a digital array valued at US$10 million was also lost in the attack, as well as disabling the research centre’s supercomputers beyond repair through the destruction of software.

Data included satellite and meteorological data used by the Roscosmos space agency, Russian Defence, emergency situations ministries and other government departments.
