LONDON (Reuters) – The website attacks launched by supporters of WikiLeaks show 21st-century cyber warfare evolving into a more amateur and anarchic affair than many predicted.
While most countries have plowed much more attention and resources into cyber security in recent years, most of the debate has focused on the threat from militant groups such as al Qaeda or mainstream state on state conflict.
But attempts to silence WikiLeaks after the leaking of some 250,000 classified State Department cables seem to have produced something rather different -- something of a popular rebellion amongst hundreds or thousands of tech-savvy activists.
"The first serious infowar is now engaged," former Grateful Dead lyricist, founder of the Electronic Frontier Foundation John Perry Barlow told his followers on Twitter last week. "The field of battle is WikiLeaks. You are the troops."
Some of the more militant elements on the Internet clearly took him at his word. A group calling itself Anonymous put the quote at the top of a webpage entitled "Operation Avenge Assange," referring to WikiLeaks founder Julian Assange.
Online collective Anonymous appears to be using social networking site Twitter to coordinate attacks on websites belonging to entities it views as trying to silence WikiLeaks.
Targets have included MasterCard, Visa and a Swiss bank. All blocked payments to WikiLeaks on apparent U.S. pressure.
The Swedish government website and Swedish prosecutors behind Assange's arrest in London for extradition and questioning over sex allegations were also hit. Some WikiLeaks supporters view the accusations as politically motivated.
Twitter and Facebook shut down accounts apparently belonging to Anonymous. But with little to stop the attackers opening new ones, few believed it would be enough to stop the campaign.
"The genie is out of the bottle and it could be very difficult to put it back in," said Jonathan Wood, global issues analyst at Control Risks.
"In more authoritarian countries such as China and Iran, they have got around this by shutting down sites such as Twitter for a certain period of time. No one thinks that is politically possible in the West."
It looks to have surprised even Barlow, whose "declaration of independence for cyberspace" has been increasingly shared over Twitter by Anonymous supporters. He says he himself opposes distributed denial of service (DDoS) attacks aimed at knocking down sites, viewing them as anti-free-speech.
"I support freedom of expression, no matter whose, so I oppose DDoS attacks regardless of their target," he told Reuters in an email. "They're the poison gas of cyberspace.... All that said, I suspect the attacks may continue until Assange is free and WikiLeaks is not under continuous assault."
