Warnings Over IS Cyber-threats

A growing band of hacktivists is helping Islamic State spread its message by attacking media organisations and websites, a security company suggests.
Supporters of IS were helping it with opportunistic attacks and more sophisticated operations, said FireEye.
French TV station TV5 Monde was a high-profile victim early this year, but attackers have hit other media groups.
FireEye said the wide range of targets made it hard to say who was at risk.
