Eric J. Rosol, 38, of Black Creek, Wis., was sentenced yesterday to two years federal probation and ordered to pay $183,000 in restitution for taking part in a DDoS attack on Koch Industries on February 28, 2011 as part of #OpWisconsin (h/t Computerworld).

Rosol pled guilty to one misdemeanor count of accessing a protected computer, admitting that he took part in a DDoS attack on Koch Industries' Web site by using the Low Orbit Ion Cannon (LOIC) tool for approximately one minute.

In a press release at the time, Anonymous stated, "The Koch's have helped to fuel the unrest in Wisconsin and the drive behind the bill to eliminate the collective bargaining power of unions in a bid to gain a monopoly over the state's power supplies."

The DDoS attack as a whole caused to go offline for approximately 15 minutes. While the direct loss from the attack was less than $5,000, the company says it hired a consulting group to protect its Web site at a cost of approximately $183,000, the amount of restitution Rosol has been ordered to pay.

Rosol is the only person to be charged in the attack.
