The perpetrators had stolen the data from the Kido nursery chain and had been demanding the company pay a ransom by bitcoin. But now, the criminals, who reportedly call themselves “Radiant,” appear to have backtracked by removing all the information online and saying they have deleted all the stolen data, Britain’s public broadcaster reported. Last week, it was reported that the information of the thousands of children from Kido was stolen by cyber hackers. The National Cyber Security Centre (NCSC), the UK’s technical authority for cyber security, described the reported incident as “deeply distressing.”CNN has reached out to the Kido nursery chain for comment. On its website, Kido says it is owned and operated by a group of parents from all over the world.
