Equifax Hackers Stole 200k Credit Card Accounts in One Fell SwoopVisa and MasterCard are sending confidential alerts to financial institutions across the United States this week, warning them about more than 200,000 credit cards that were stolen in the epic data breach announced last week at big-three credit bureau Equifax. At first glance, the private notices obtained by KrebsOnSecurity appear to suggest that hackers were first able to steal credit card numbers from Equifax starting in November 2016. But Equifax says the accounts were all stolen at the same time -- when hackers accessed the company's systems in mid-May 2017.
