Two of Equifax's top executives are leaving the company a week after a massive data hack compromised the personal information of 143 million Americans.

The credit reporting agency announced Friday evening that chief information officer David Webb and chief security officer Susan Mauldin would be "retiring" effective immediately.

Notably, neither of the execs were among the three who raised suspicions of insider trading when they unloaded nearly $2 million of the company's stock in the days before revealing the hack to the public.

The departures come as regulatory investigations, congressional inquiries, and class-action lawsuits are piling up against the company. Most recently, Massachusetts Sen. Elizabeth Warren, the architect of the watchdog Consumer Financial Protection Bureau, introduced her own probe and a bill that would reform how Equifax operates.

The company also said in the announcement that its investigation into the breach is still ongoing and it's working with the FBI.

Equifax's stock has lost around 35 percent of its value since the company first disclosed the attack last Thursday.
