Origin Energy, one of Australia's largest energy retailers, has confirmed that personal data of about 900,000 customers was accessed during a cyber attack. The breach, which the company says it discovered earlier this month, involved the theft of names, addresses, phone numbers, email addresses, and in some cases billing information. Origin has since launched an investigation with external cybersecurity experts and alerted the Australian Cyber Security Centre. The company has also begun notifying affected customers, advising them to be wary of phishing emails and unusual account activity. However, reports indicate that Origin was warned of a potential vulnerability weeks before the breach was made public, raising questions about the timing of the announcement. Chief Executive Officer Frank Calabria apologized on Monday, stating that the company deeply regrets the incident. He emphasized that Origin is implementing enhanced security measures and will offer credit monitoring to impacted individuals. The breach, which did not compromise bank details or sensitive financial data, still exposes customers to increased risk of targeted scams. Authorities are investigating, but so far no arrests have been made. Customers are urged to remain vigilant and report any suspicious activity.
