“‘ISIS [also known as Islamic State] came onto the scene very quickly, but they already have arguably the best cyber offensive capability of any extremist movement out there, and it’s still early days,’ Mikko Hypponen, chief research officer at F-Secure said.
‘We still haven’t seen real physical damage being done by any extremist group, and it’s probably going to take a while until we see it. But these guys are the first ones that actually have some existing hackers who have joined them and moved in from the West,’ Hypponen told the AusCERT Information Security Conference on Australia’s Gold Coast in his keynote address on Friday morning.”
