NEW: David Vincenzetti, the founder of spyware maker Hacking Team, has been arrested.
Vincenzetti is accused of attempted murder. He allegedly stabbed a relative at his home. A judge has ordered him to stay in prison as a precautionary measure, and has ordered a psychological evaluation, according to Italian media reports.
I'm honestly in shock. Hacking Team's story is still getting crazier, eight years after it got spectacularly hacked.
