Hackers accessed part of the state computer system Wednesday.
A number of state Web sites were down because of the hacking, which first was noticed Sept. 11, Utah Division of Information Technology Services Director Dave Fletcher said.
State computer experts do not believe the hackers penetrated the applications that have information for credit card payments. The ITS is working with local law enforcement and the FBI to investigate the matter, according to a statement by the Utah Department of Administrative Services.
The hacking at most amounted to an inconvenience, Fletcher said.
