Equifax faces at least 23 proposed class-action lawsuits since its disclosure that personal identifying information for 143 million U.S. consumers may have been compromised by a massive cyberbreach.
And additional cases are likely to come.
Federal court records show the lawsuits were filed through the weekend after the credit-reporting giant's Thursday disclosure that a cyberattack by criminal hackers provided unauthorized access to information for nearly 44% of the U.S. population.
Separately, Sens. Orrin Hatch, R-Utah, and Ron Wyden, D-Oregon, respectively the chairman and ranking member of the Senate Committee on Finance, sent Equifax detailed questions about the breach on Monday.
