I don’t think so. They all have their security measures but they all have the same vulnerability too. There may be different doorways for each country but they are all opened with some kind of key. What would stop ISIS from using those keys on the country that helped them at some point. I don’t think a country can exploit another contries vulnerability without showing a least some of their own. The only way I see ISIS getting this tech is if they manage to kidnap a hacker or scientist or maybe Iran might help them. The other drawback with a country helping them is if ISIS gets caught then the US has that countries play book.
