Could Equifax have suffered a second data breach following the massive hack exposing the personal information of more than 145.5 million consumers? It’s possible, according to a security researcher who claims to have found a second, separate security vulnerability within the company.

Motherboard reports that in late 2016, a security researcher tipped off Equifax to a security flaw after finding a webpage that could have allowed anyone to access the personal information of consumers.
