LONDON—British intelligence officials believe that a group linked to North Korea perpetrated last month’s massive cyberattack, which crippled computer networks at British hospitals and other organizations around the world, a person familiar with the investigation said Friday.
South Korea and some major cybersecurity firms have previously concluded the attack was perpetrated by the North Korean hacking group, dubbed “Lazarus, ” which had previously been implicated in the 2014 hacking of Sony Entertainment. Most other governments, including British officials, haven’ t publicly commented on any conclusions about who they believe was responsible for the attack.
