SEC reveals 2016 hack that breached its filing system

The Securities and Exchange Commission waited until Wednesday to disclose a hack of its corporate filing system that occurred last year. The disclosure raises questions about the agency's ability to protect important financial information and comes as Americans are still weighing the consequences of the massive hack at Equifax.

The SEC, as the federal agency responsible for ensure that markets function properly and for protecting investors, is under fire after disclosing the hack of its electronic network for whisking company news and data to investors. The breach occurred despite repeated warnings in recent years about weaknesses in the agency's cybersecurity controls.
