Last week we reported that the website of the UK’s Serious Organised Crime Agency (SOCA) was brought down by hackers who staged a DDoS attack. Now it has emerged that two teenagers in Norway have been arrested for a series of computer attacks with SOCA believed to have been one of their targets.

There may be further arrests or at the very least more people brought in for questioning, with Norwegian prosecutor Erik Moestue quoted as saying: “We have arrested the two we think were most important in these attacks, but we still want to talk to more people.”

He added: “We know SOCA was recently attacked, as well as Norwegian and American sites, and that is one of the things that we are looking into.”

A spokesperson for Norway’s National Criminal Investigation Service said that the sites in Norway and America had also been hit by a DDoS attack. The two suspects, aged 18 and 19, were charged at the end of last week after a period of sustained electronic attacks going on for several weeks.

Mr Moestue said the case was still under investigation and that it was too early to discuss the motive for the attacks. However, if the pair are found guilty then the maximum sentence for the offences they are being charged with is a six-year jail term.

A Norwegian press agency reported that the country’s largest financial services group DNB has been attacked, along with the Police Security Service, but NCIS would not confirm this.
