A man suspected of being the hacker behind the Black Hole malware virus has been arrested in Russia. The individual, known by the alias Paunch, is believed to have created the Blackhole and Cool exploit kits which were sold to infect computers with malware. While Europol confirmed a cybercriminal was arrested, details have not been provided by Russian authorities. Paunch's arrest may not eliminate the threat as other hackers continue operating similar malware kits.
