London Hydro says a security incident may have exposed customer account information for some electricity users in and around London, Ontario. The utility said affected data can include names, addresses, email addresses, phone numbers, account and billing numbers, service addresses, pricing plans, contract start dates, and meter information. It has not yet disclosed the attack method, whether data was stolen or only accessed, how many customers were affected, whether ransomware or a third party was involved, or whether operational grid systems were touched.
Why it matters: Customers could face convincing phishing, billing fraud, or impersonation scams using real account details, even if payment-card and banking data were not involved. Affected users should watch for suspicious utility messages and account changes, while defenders should seek more detail on scope, intrusion path, and any impact on utility operations.
