A hacker once considered "the Internet’s most inept criminal" received on Monday a prison sentence of 20 months in prison for launching DDoS attacks against the city of Madison, Wisconsin —attacks which caused delays and outages to various municipality services, including its 911 emergency call center.

The DDoS attacks took place between March 9 and March 14, 2015, and the man's name is Randall Charles Tucker, 23, a hacker who went online under the pseudonym of "Bitcoin Baron."
