From Cold War to Gray War: Internet Conflict Intensifying Jamie Dettmer A former top security adviser to Boris Johnson has revealed that Britain has launched recently a series of covert cyber-based attacks on Russian leaders and their interests to "impose a price greater than one they might have expected" for their cyber-offensive against the West.'¯ Other allied powers, including the U.S., are doing so, too, say Western intelligence officials in what is becoming a "like-for-like" cyber-conflict with the Kremlin in the so-called the "gray space," the gap between normal state relations and armed conflict. "The fact you don't see that we use it doesn't mean we don't, because we wouldn't necessarily talk about those things," said Mark Sedwill, until recently Britain's top civil servant and national security adviser to Britain's Boris Johnson. But in an interview with The Times newspaper, Sedwill underscored that Britain is using its cyber-offense capabilities to retaliate for Russian cyberattacks, information warfare and disruption campaigns. .
