We've just learned from a Czech site www.viry.cz that the Czech police raided the apartment of "Benny" last Thursday. Benny is a well-known virus writer who used to be one the most visible members of the virus-writing group 29A. For example, Benny was interviewed by the New York Times in February 2004.
Apparently the police is investigating Benny in relation to the Slammer internet worm. Slammer, found in January 2003, was the single largest attack against internet, ever.
However, we do not think Benny wrote Slammer.
Another member of the group, known as "Whale", was sentenced few weeks ago in Russia. Two other members, known as "Ratter" and "disk69" have just announced that they are leaving the group.
