Australia’s largest energy retailer has told the ASX that some customer information may have been accessed without authorisation, though it says card and bank details appear untouched.

Origin Energy, Australia’s largest electricity and gas retailer, told the Australian Securities Exchange on 22 July that it is investigating potential unauthorised access to some of its customers’ data.

The company said it does not believe the affected information includes credit card or bank details, though it stopped short of saying how many people had been caught up in the incident.

The disclosure arrives in a year already thick with corporate intrusions, from a supply-chain compromise at Klue that spilled LastPass customer records to the second extortion group that surfaced weeks later to press its own demands.

Origin’s statement is, for now, notably thin on detail, which is either prudence or the early fog of an investigation that has not yet run its course.
