The concern in the FBI and intelligence community is that ISIS members overseas are tracking personal information about `` specific '' U.S. soldiers -- - such as their addresses and even their relatives addresses -- based on their social media posts , according to a law enforcement official briefed on the matter . The FBI issued a bulletin on Sunday warning servicemen and women of possible ISIS threats . A U.S. official told CNN that the threat is not specific to any particular group but rather refers to "lone wolf" attacks by individuals who are inspired or directed by ISIS.
