A hacker reportedly stole ~11mil records of customer PII (dated 2017) from Optus, an Australian telco company. The data was disclosed and put on sale in late September 22’. According to information obtained by a reporter who claimed to be in contact with the hacker, the root cause was an unintentionally publicly exposed Apigee API endpoint, which was misconfigured to allow unauthenticated access.
