The shake-up announced Tuesday comes after Equifax disclosed that hackers exploited a software flaw that the company didn’t fix to heist Social Security numbers, birthdates and other personal data that provide the keys to identify theft.

Smith had been Equifax’s CEO since 2005. Paulino do Rego Barros Jr. was named interim CEO.

Although many analysts had applauded Equifax’s performance under Smith, he and the rest of his management team had come under fire for lax security and its response to the breach.

Smith’s departure follows the abrupt retirement of Equifax’s chief security officer and chief information officer.
