We've all heard of websites crashing because of too much traffic. Investigators are saying that Scott Arciszewski intentionally caused so many computers to connect to the Infragard website that it crashed.. allowing him to gain access to information.
In order to do that, they say he spread a virus to thousands.. even millions of home computers.
The virus then made the computers connect to Infragard at the same time.
That causes the site to overload.. and within seconds the hacker gained access to the entire site.
"The computers that are out there doing the attacking are probably home computers that don't have up to date anti-virus that probably have maybe a fire wall so if you have a home computer the best thing you can do is keep your anti-virus up to date and keep your firewall on," said computer expert Jack Voth.
Since Arciszewski accessed the site Infragard website, the FBI was able to track down the location of his computer and make their arrest.
