- NEW YORK: Major banks and credit-card issuers Capital One, Barclays Bank, US Bancorp and Citigroup have joined the list of companies warning customers that hackers may have learned their e-mail addresses.
The companies all use a Dallas-based company called Epsilon to manage their e-mails to customers. Epsilon said Friday that its system had been breached, exposing e-mail addresses and customer names but no other personal information.
The hackers also gained access to the e-mail addresses of customers of JPMorgan Chase & Co., Best Buy Co., TiVo Inc., Walgreen Co. and Kroger Co.
The affected companies said the e-mail addresses could be used to target “phishing” attacks — seemingly legitimate e-mails that try to coax account login information from victims.
