Web attack against Twitter - aimed at one blogger

BBC

A "massively co-ordinated" attack on websites including Google, Facebook and Twitter was directed at one individual, it has been confirmed.

Facebook told BBC News that the strike was aimed at a pro-Georgian blogger known as Cyxymu.

The attack caused a blackout of Twitter for around two hours, while Facebook said its service had been "degraded".

Google said it had defended its sites and was now working with the other companies to investigate the attack.

"[The] attack appears to be directed at an individual who has a presence on a number of sites, rather than the sites themselves," a Facebook spokesman told BBC News.

"Specifically, the person is an activist blogger and a botnet was directed to request his pages at such a rate that it impacted service for other users."

Botnets are networks of computers under the control of hackers.

The machines were used to mount a so-called denial-of-service (DOS) attack on Thursday. [...]
