A Wisconsin man recruited by the computer hacking group Anonymous faces charges in a cyberattack on Koch Industries in Wichita, a federal prosecutor announced Tuesday.

Eric J. Rosol, of Black Creek, Wis., is accused of one count of conspiracy to damage a protected computer and a single count of damaging a protected computer, U.S. Attorney Barry Grissom said in a news release. An indictment filed in federal court alleges Rosol, 37, participated in an Anonymous-organized cyberattack on on Feb. 28, 2011. The attack used a tool called a Low Orbit Ion Cannon, which sent “a high volume of repeated requests” to the Koch Industries website and disabled it, Grissom said.

The group also told conspirators to launch a similar attack on, another Koch Industries website, the day before, he said.

Grissom said Anonymous used Internet Relay Chat channels to recruit people interested in participating in a “dedicated denial of service” attack on the Koch Industries sites in February 2011. Such cyberattacks saturate targeted computers with numerous external communication requests, making them sluggish or unable to respond effectively to legitimate users, he said.

Rosol faces up to five years in federal prison and a maximum fine of $250,000 on each count, if convicted, Grissom said.
