The FBI issued a warning Sunday to members of the U.S. military that ISIS is calling for attacks against them , according to a law enforcement source , saying that `` overseas based individuals are looking for like-minded individuals in the U.S. to carry out these attacks . '' `` We also request members of the military review their online social media presence for any information that might attract the attention of violent extremists , '' the bulletin said , advising that members of the military `` use caution and practice operational security when posting . '' The new FBI bulletin includes a concern that ISIS members are `` spotting and assessing '' individuals in the U.S. who they believe may be interested in carrying out attacks on U.S. soil against members of the U.S. military , a U.S. counter-terror official tells CNN . The bulletin language warns of `` individuals overseas spotting and assessing '' individuals in the U.S. , based on their social media postings in support of the group . The warning encourages members of the military to `` exercise operational security '' in response to such threats , including reviewing their online social media postings so as not to make themselves easier targets . U.S. law enforcement posted the warning now in advance of the upcoming holiday season when many members of the U.S. military travel in uniform . The new warning also cites several recent attacks in Canada against members of the Canadian military , including the Oct. 22 Ottawa shooting and two other attacks using cars . 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 concern is that ISIS operatives are gathering it overseas and then identifying homegrown violent extremists in the U.S who could help carry out the attack . The source says the idea is basically `` I do n't have to come and get him -- I can call someone in the U.S. who wants to support the cause and they can do it . '' The FBI is working very closely with the military and intelligence community to address the issue . A Pentagon spokesman said Monday morning that the bulletin `` reinforces the guidance our combat commanders put out several weeks ago . This is nothing new for us . '' Col. Steve Warren , the Pentagon spokesman , said he was `` aware of no new intelligence '' that led to the bulletin being sent . The FBI also issued a security bulletin in October warning of similar attacks on U.S. soil against law enforcement personnel and members of the news media . Terrorism and security experts have expressed growing concerns in recent months that ISIS could inspire individuals in the West to carry out terrorist attacks . Australian authorities in September foiled an ISIS-inspired plot to kidnap and publicly behead someone in public . Iraq 's army weakened from within by 50,000 'ghost ' soldiers .
The FBI issued a bulletin on Sunday warning servicemen and women of possible ISIS threats . The memo asked members of the media to review their social media profiles .
