Hackers stole funds from approximately Amazon.com Inc. Seller Central merchant accounts during a six-month period in 2018.

Between May and October 2018 the miscreants nicked cash from the accounts and directed the money into their own Barclay plc and Prepaid Technologies Ltd. accounts, Bloomberg cited a formerly redacted U.K. legal filing as saying.

In the legal document Amazon lawyers said the company needed records from Barclay and Prepaid Technologies “to investigate the fraud, identify and pursue the wrongdoers, locate the whereabouts of misappropriated funds, bring the fraud to an end and deter future wrongdoing.”
