Experts who track the group closely say that when it comes to attacks in the West , if ISIS is claiming responsibility , there typically was some kind of connection between the perpetrator and the group . ... until recently , claims of responsibility put out through official channels were seen as reliable . " However , " That might be changing , " as ISIS loses territorial sovereignty in Syria .

In addition , the claim of an ISIS connection to the 2017 Las Vegas shooting appeared to be false
