The unnamed youngsters,18 and 19 year-olds , have been arrested by Norway's National Criminal Investigation Service (NCIS) , according to The Inquirer report.
"We have arrested the two we think were most important in these attacks, but we still want to talk to more people," said Norwegian prosecutor Erik Moestue.
"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."
If found guilty of the offence under Norwegian law the two could face maximum six year jail sentences.
