Cyber-attacks on press up in number, down in cost

Novaya Gazeta, a leading Russian independent news outlet, has been under cyber-attack.

The last two weeks have seen a spate of denial-of-service (DOS) attacks against news sites, coordinated attempts to overwhelm outlets with fake incoming data so the sites cannot respond to legitimate users.

Protecting yourself from denial-of-service attacks

It's my second link to a report by Hal Roberts (and others at the Berkman Center) in as many days, but I worry that this this detailed document on denial-of-service (DOS) and hacking attacks on independent media and human rights groups might get missed in the holiday season.

The news headlines in the last few weeks have been full of stories of how DOS attacks can bring down even high-profile websites, often with relatively little technical expertise on behalf of the attackers. Such attacks are nothing new to online journalists across the world, however. Just this year, CPJ has dealt with cases of independent news sites being taken offline by remote Internet attacks in China, Burma, Vietnam, Russia, Kazakhstan, and now Belarus.

The Berkman Center's report details over three hundred other cases from 1998 onwards, from Sweden to North Korea. More important, the researchers interviewed the victims of these attacks, and categorized what defenses were practical and effective -- and what did not work.

If you're an online journalist with powerful opponents, I'd strongly encourage you to read this document and pass it along to your tech-savvy associates. Even a small amount of preparation can help keep vital news and opinion available online when you -- and your readers -- most need it.
