CommonDreams.org published a press release by Anonymous http://www.commondreams.org/further/2011/02/28-0

They announced an open and collaborative effort to hack Koch Industries, owned by the billionaire Koch brothers who are accused of undermining democracy.

They said they are "actively seeking vulnerabilities", meaning they wish to build a library of knowledge about systems owned or used by Koch companies and organizations.

They have called for a boycott of Georgia Pacific paper products including Brawny, Angel Soft, and others listed at the link above. (There's already been a boycott called by various progressive groups, and while they may think they are "leading", they are only one of many.)

This action follows on the heels of Gov. Scott Walker of WI being "punk'd" by the Buffalo Beast blog, which posed as David Koch to talk to Walker. in the released conversation, Walker buddied up with Koch and told him that, basically, he was willing to further Koch's corporate political agenda. This includes not only planning to insert agent provacateurs among protesters, but also includes evidence that Walker would take a "gift" from Koch (which is illegal).

In response, GOP legislatures are proposing a law making it illegal to impersonate someone while talking to a politician. http://www.buffalobeast.com/?p=5162 Who said blogs don't matter?

Last month, Anonymous compromised the minimal security of HB Gary Federal, a "security" company that was seeking contracts in the defense industry. HB Gary specialized in both preventing computer intrusions, and according to emails released by Anonymous, aiding the US government in performing computer intrusions.

Among the emails, researchers at Think Progress and other blogs have found that HB Gary was part of a group named Team Themis that was shopping around a plan to use fake identities to post conservative talking points and disruptive comments on social networks and news sites. Among their targets were progressive/left organizations and labor unions.

The "hacks" used against HB Gary were relatively simple, and the company was "taken down" quickly - revealing that this security company lacked basic security common sense. The upshot - HB Gary was trying to sell the company, but the market value had dropped to nothing.

Can Anonymous pull off a crack of Koch? Perhaps. Announcing it in public is unusual, and may indicate that Koch is already tough to crack. On the other hand, there may be some leaks that would make is easier.
