In the wired age, "Twitter bombs" that spam feeds with militant propaganda are as much a part of the modern jihadi’s arsenal as bullets. But with every burst of online messaging from extremists comes potential blowback.

If you’re a Russian citizen these days, it is easier than ever to support the insurgency in eastern Ukraine, now nearly three months old.  With the click of a mouse, you can transfer money through Sberbank – Russia’s largest bank, which is government controlled – to grassroots organizations supplying separatist rebels with weapons and personnel.

The Islamic State of Iraq and Syria has taken to Twitter to spread its message, trumpet bloody successes, and recruit potential jihadists, but its social-media campaign has come under attack from forces that range from the U.S. State Department to the mysterious group of hacker-activists who call themselves Anonymous.
