Two Floridians have been indicted in New Jersey on charges of computer and impersonation crimes for allegedly disrupting an online business and causing almost $900,000 in losses.

Attorney General Anne Milgram and Criminal Justice Director Gregory A. Paw announced this week that a grand jury indicted Rory Edward Tringali, 36, and his Miami Beach neighbor, Matthew Justin Willner, 34, on first-degree charges of computer criminal activity and conspiracy to commit computer criminal activity, as well as second-degree charges of impersonation, conspiracy to commit impersonation, and attempted computer criminal activity.

The indictment (PDF) claims that Tringali was fired from his consulting job with MedPro, a Web-based company that sells lasers for about $100,000 each, in 2003. It claims he retaliated by paying Willner to disrupt the company's Web sites between November 2006 and March 2007.

The indictment states that the computer attacks impaired MedPro's ability to do business and blocked customer communication. It also claims the pair sent spam that looked like it had come from MedPro.

Detectives from the New Jersey Division of Criminal Justice -- Computer Analysis and Technology Unit and state prosecutors believe that MedPro changed domain names twice, but Tringali and Willner attacked the new sites. The online medical supplier claims more than $894,000 in losses as a result of the spam and Web site disruptions.

Tringali was arrested in Florida and extradited to New Jersey. Willner was arrested in Florida and agreed to turn himself over to authorities in New Jersey.

If the men are found guilty, they could face a maximum sentence of 20 years in state prison and a fine of $200,000 on the first-degree charges and a maximum sentence of 10 years in state prison and a fine of $150,000 for the second-degree charges.
