BBC News reports that Russian police have arrested a man on suspicion of creating both the Blackhole and Cool exploit kits.

Fox-IT security researcher Maarten Boone first announced the arrest on Twitter, stating, "BREAKING: Blackhole exploit kit author 'Paunch' and his partners arrested in Russia."

While Russian authorities haven't confirmed the arrest, a Europol spokesman told the BBC, "Europol and the European Cybercrime Centre has been informed that a high-level suspected cyber criminal has been arrested. We can only refer to the Russian authorities, they are the ones who should speak about this topic."

And Malwarebytes reports that, according to security researcher Kafeine, while "Paunch" usually updates the Blackhole exploit kit once or twice a day, it hasn't been updated for at least four days at this point.

"In all likelihood, we are going to see cyber-crooks migrate their infrastructure towards other exploit kits very soon," suggests Malwarebytes senior security researcher Jerome Segura.
