A Canadian teenager accused of immobilising some of the Internet's most popular Web sites through a denial-of-service (DoS) attack in February has offered a plea of not guilty in a Montreal courtroom.
Under Canadian juvenile law, the identity of the 16-year-old boy, who allegedly operated under the screen name of "MafiaBoy," cannot be released.
The teenager could face dozens of new charges of hacking and mischief in addition to those offences he was indicted for in April.
Those earlier charges include two counts of mischief to data on the Web sites of CNN and the more than 1,200 Web sites it was hosting on 8 February.
During February's well-publicised distributed DoS attacks, visitors to the Web sites of Internet giants including CNN, EBay, Yahoo, Amazon.com, and ETrade were locked out for hours as the sites lay crippled under the DoS onslaught.
Authorities say the teen launched his attack by using computers from various American universities as "zombies" to flood the popular Internet sites with bogus data packets, overloading access to them.
A trial date for the accused suspect will be set 28 September.
