A former computer support technician will serve one year in prison for hacking into his former employer's computer network and causing more than $30,000 worth of damage.

Lesmany Nunez, 30, of Miami, pleaded guilty in federal court in Miami on Tuesday to charges of computer fraud, after he was accused of hacking into the computer network of his former employer, IT network and design company Quantum Technology Partners (QTP), according to the U.S. Attorney's Office.

Nunez accessed QTP's computer network from home by using an administrator username and password, changed the passwords of all the IT system administrators, shut down most of the company's servers, and deleted other files.

Because of Nunez's actions, QTP could not operate its business normally for several days and incurred more than $30,000 in cost responding to the incident, assessing the damage done and restoring the system to its previous condition, the U.S Attorney's Office said in a news release.

FBI investigators traced the activity on QTP's network to Nunez's home computer.

Nunez was also ordered to pay $31,560 in restitution. After completing his prison sentence, Nunez must serve three years of supervised release and perform 100 hours of community service in which he will lecture youths about the consequences of hacking.

A spokesperson at QTP could not be immediately reached.
