The United Kingdom on Sunday announced a “major expansion” to its Ukraine Cyber Program, which has seen British experts provide remote incident response support to the Ukrainian government following Russian cyberattacks on critical infrastructure.

It follows the British government last year announcing that personnel from cyber and signals intelligence agency GCHQ had been contributing to Ukraine’s defense, including by providing protection against the Industroyer2 malware, alongside delivering hardware and software and limiting “attacker access to vital networks.”

The new funding will also support the provision of “forensic capabilities to enable Ukrainian cyber experts to analyze system compromises, attribute attackers and build better evidence to prosecute these indiscriminate attacks,” said Number 10.
