A group called New World Hacking has claimed responsibility for an attack that brought down the BBC's website for several hours on Thursday.
The group says it goes after Islamic State (ISIS) online activity, but carried out the BBC attack to test its capabilities. A BBC source said it was a "distributed denial of service" (DDOS) attack, in which a target is bombarded with traffic from multiple sources to try and overwhelm it.
"It was only a test, we didn't exactly plan to take it down for multiple hours. Our servers are quite strong," the group said, according to the BBC.The BBC corporation said it won't be commenting on the group's claim. It wouldn't confirm or deny that the reason for the website being down Thursday was a DDOS attack. In a message to BBC technology correspondent Rory Cellan-Jones, New World Hacking said: "We realize sometimes what we do is not always the right choice, but without cyber hackers... who is there to fight off online terrorists? The reason we really targeted BBC is because we wanted to see our actual server power."
