ATLANTA — Credit monitoring company Equifax says a breach exposed social security numbers and other data from about 143 million Americans.

The Atlanta-based company said Thursday that “criminals” exploited a U.S. website application to access files between mid-May and July of this year.

Consumers’ names, Social Security numbers, birth dates, addresses and, in some cases, driver’s license numbers were exposed, it said. Credit card numbers for about 209,000 U.S. consumers were also accessed.

Hackers also accessed some “limited personal information” from British and Canadian residents, the company said.

Equifax said it doesn’t believe that any consumers from other countries were affected.
