Koch Industries Braces for Another Cyber Attack

Koch Industries, the Wichita-based private conglomerate run by the billionaire Koch brothers, is bracing for another cyber attack, a cyber security source told FOXBusiness.com.

Group Anonymous, which has often aligned itself with the Occupy Wall Street movement, is believed to be behind the potential attack, which is expected to occur on Friday.

Anonymous was also behind a cyber attack last year on the business websites of Koch.

“They were really attacked last year and are burn victims. They clearly take the threats very seriously,” the source said.

It’s not clear what Koch is doing to defend itself from the latest potential attack. Koch didn’t immediately respond to a request for comment.

The Koch brothers, Charles and David, are frequent Republican campaign donors and have been vilified by those on the political "left." According to OpenSecrets.org, in every election cycle since 2000, people and political action committees associated with Koch Industries have given at least 83% of their donations to Republican candidates.

With about $98 billion in annual revenue, Koch Industries was ranked by Forbes in 2011 as the second-largest privately held company in the U.S., trailing just Cargill. The conglomerate and its subsidiaries touch a range of industries, including refining and chemicals, minerals, ranching and pollution control.

The latest threat against Koch comes after a series of recent cyber attacks, including one on Tuesday that brought down the websites of the Nasdaq Stock Market, which is owned by Nasdaq OMX Group (NASDAQ:NDAQ).
