What started out as an attempt to overload a small set of official sites has now expanded, network security consultant Dancho Danchev notes. News outlets like Raja News are being attacked, too. The semi-official Fars News site is currently unavailable.
“We turned our collective power and outrage into a serious weapon that we could use at our will, without ever having to feel the consequences. We practiced distributed, citizen-based warfare,” writes Matthew Burton, a former U.S. intelligence analyst who joined in the online assaults, thanks to a “push-button tool that would, upon your click, immediately start bombarding 10 Web sites with requests.”
But the tactic of launching these distributed denial of service, or DDOS, attacks remains hugely controversial.
Other online supporters of the so-called “Green Revolution” worry about the ethics of a democracy-promotion movement inhibitting their foes’ free speech. A third group is concerned that the DDOS strikes could eat up the limited amount of bandwidth available inside Iran — bandwidth being used by the opposition to spread its message by Twitter, Facebook, and YouTube. “Quit with the DDOS attacks — they’re just slowing down Iranian traffic and making it more difficult for the protesters to Tweet,” says one online activist.
