The Egregor ransomware gang claims to have taken responsibility for the Barnes & Noble cyberattack, first disclosed on Oct. 15. The bookseller warned customers last week that it had been hacked in emailed notices to customers. The gang claimed to have stolen unencrypted financial and audit data, but it hasn t yet confirmed that. It also published two Windows Registry hives that appear to have been exported from the bookseller s Windows servers during the attack, according to media reports.
