Cybercriminals who stole pictures and the private information of thousands of nursery children have deleted the data. A gang calling themselves Radiant have removed details of children at the UK-based Kido nursery chain from a website it had set up to extort victims. A cybersecurity source confirmed to the Guardian that profiles of children had been removed from the site, which has been reformatted. A Kido spokesperson confirmed the attackers had removed information that they had previously published. The BBC reported that Radiant had demanded £600,000 in bitcoin from Kido to return the data but that Kido had not paid the ransom.
