The dude who tried to break into Paris Hilton's Hollywood Hills home while holding two big knives was just found GUILTY of first-degree residential burglary.
It took the jury less than an hour to convict Nathan Lee Parada of trying to break into the socialite's home last August.
As TMZ first reported, Parada was thwarted by Hilton's boyfriend Cy Waits ... who pulled a gun on the suspect before the dude could get inside.
Parada is set to be sentenced on June 29. He faces up to three years in state prison.
