Spanish authorities over the weekend busted a group of young hackersaccused of targeting a number of U.S. and foreign government websites.

Five hackers — known as the D.O.M Team and ranging in age from 16 to 20– were charged with compromising roughly 21,000 web pages over twoyears, according to published reports. Targets included Asian, LatinAmerican and U.S. government agencies, but a statement from theNational Police agency in Spain did not specify which ones.

A Spanish newspaper, El Mundo, reported in March that oneof the U.S. targets was NASA. A spokesman for the space agency did notreturn a call by SCMagazineUS.com seeking comment.

The paper also reported that the hacker team was responsible forintrusions into the website for Venezuela’s telephone operator.

Thegroup apparently broke into websites to prove the sites are vulnerable toattack and were not out to cause financial harm

The suspects were arrested in Barcelona, Burgos, Malaga and Valencia.
