The most serious cyberattacks in the U.K. are now carried out by hostile nations including Russia, Iran and China, the head of the U.K.’s National Cyber Security Centre (NCSC) said in a speech Wednesday.
Richard Horne, the head of the NCSC — part of the U.K’s signals intelligence agency GCHQ — warned that the U.K. is living through “the most seismic geopolitical shift in modern history.” British businesses, he said, need to prepare themselves to defend against cyberattacks because the U.K. could be targeted “at scale,” if it became involved in an international conflict.
In recent months, authorities in Sweden, Poland, Denmark and Norway have all warned that hackers linked to Russia have targeted their critical infrastructure including power plants and dams.
