HBO, which acknowledged Monday, July 31, 2017, that hackers had broken into its systems and stolen “proprietary information,” now says the attackers likely haven’t breached the network’s entire email system. In an email to employees on Wednesday, Aug. 2, Plepler wrote that “we do not believe that our email system as a whole has been compromised.” (Photo by Charles Sykes/Invision/AP, File)
