“Yahoo is facing lawsuits from people who fear their accounts have been hacked and claim the company was “grossly negligent,” putting their financial and personal data at risk.

Two lawsuits, both filed in California, also allege that Yahoo (YAHOF) did not adequately disclose the breach that exposed private information of at least 500 million users.

A lawsuit filed Thursday in the U.S. District Court in San Diego alleges the hack leaked personal information and caused an “intrusion into personal financial matters.” A similar complaint filed in the U.S. District Court in San Jose on Friday says Yahoo was “grossly negligent” in dealing with and reporting the security breach.”
