Protecting consumer data has been a focus of attorney general multistate efforts. Recent efforts include addressing major data breaches affecting consumers nationwide. For example, after consumer reporting agency Equifax announced a massive data breach in 2017 affecting nearly 150 million consumers, a multistate coalition of attorneys general launched an investigation into Equifax's data security measures. The investigation found that Equifax failed to institute adequate security measures and knew about but failed to correct a critical vulnerability in its software, all of which contributed to this significant release of consumer information.
