Specifically, the OIG's Cyber Investigations Office (CYB ER) was asked to attempt recovery of these missing text messages for the referenced period from FBI issued mobile devices issued to Strzok and Page. The OIG asked the FBI Inspection Division to locate the FBI issued Samsung Galaxy S5 devices formerly assigned to the subject employees and to obtain from the same individuals their assigned FBI issued Samsung Galaxy S7 devices. The FBI provided these four devices to the OIG in late January 2018. CYBER utilized digital forensic tools to obtain data extractions from the four FBI issued mobile devices. To ensure the thoroughness of text message recovery efforts, OIG also consulted with the Department of Defense, conducted additional quality assurance steps and hired a Subject Matter Expert. The result of these steps was the recovery of thousands of text messages within the period of the missing text messages, December 15, 2016 through May 17, 2017, as well as hundreds of other text messages outside the gap lime period that had not been produced by the FBI due to technical problems with its text message collection tool. In view of the content of many of the text messages between Strzok and Page, the OIG also asked the Special Counsel's Office (SCO) to provide to the OIG the DOJ issued iPhones that had been assigned to Strzok and Page during their respective assignments to the SCO.
