San Francisco is first city to sue Equifax over data breach

SAN FRANCISCO (KFSN) -- San Francisco is the first city to sue Equifax over a massive data breach that exposed the personal information of about 143 million Americans.

The city filed a lawsuit Tuesday against the credit reporting company in a California court. It accuses Equifax of violating state law by failing to implement reasonable security measures and not providing timely notice of the breach.

The suit seeks tens of millions of dollars in civil penalties and restitution for some consumers.

Equifax declined to comment on the pending litigation, but says it remains focused on helping its customers.

The state of Massachusetts has also sued Equifax over the breach, and the company is facing scrutiny from Congress. San Francisco's lawsuit was filed on the same day that Equifax chief executive Richard Smith stepped down.
