On Wednesday, the Yedioth Ahronoth newspaper reported that outside party as being Cellebrite, an Israeli phone forensics firm, attributing the information to "sources in the field/industry well acquainted with the subject." Haaretz reported that "While the Cellebrite executives would not comment on the San Bernardino case, they indicated they are confident that a completely hack-proof phone has not been invented yet and that they would eventually be able to unlock any existing system on their own." Leeor Ben-Peretz, executive vice president of products and business development for mobile forensics at Cellebrite told Haaretz, "The level of complexity is exponential and it's at a point that it's getting difficult—but if anyone can do it, it's us."

When contacted by phone, Cellebrite would not confirm the accuracy of those reports, and the FBI did not immediately respond to a request for comment.
