• Russia’s cyber-reversals haven’t resulted from lack of trying. Microsoft counts nearly 40 Russian destructive attacks between Feb. 23 and April 8, and Rob Joyce, the National Security Agency’s cybersecurity director, said the Russians had attempted an “enormous” cyber offensive. The Russians sabotaged a satellite communications network called Viasat in the opening days of the war, for example, with the damage spilling over into other European countries.
  • But Ukraine, working with private tech companies, Western intelligence and its own expert software engineers, has quickly fixed most of the damage. “The Ukrainians have gotten really good at repairing networks,” says Dmitri Alperovitch, a Russian-born cybersecurity expert who co-founded CrowdStrike. “When a network gets wiped, they rebuild it in several hours.”
