Deep Root has confirmed the authenticity of the .
“Since this event has come to our attention, we have updated the access settings and put protocols in place to prevent further access,” Alex Lundry, the company’s founder, told Gizmodo.
UpGuard’s team discovered that the company hosted an additional 24 terabytes of data that was not publicly accessible, including documents related to GOP strategist Karl Rove’s American Crossroads super PAC.
