The Kid, the F-Bomb, and the Chinese Skype Code

By Vernon Silver | March 08, 2013 | Bloomberg BusinessWeek

Jeffrey Knockel is an unlikely candidate to expose Skype’s role in China’s online surveillance apparatus. The 27-year-old computer science graduate student at the University of New Mexico in Albuquerque doesn’t speak Chinese, let alone follow Chinese politics. “I don’t really keep up with news in China that much,” he says. What gets him going are puzzles.

So when a professor pulled Knockel aside after class two years ago and suggested a long-shot project—to figure out how the Chinese version of Microsoft’s (MSFT) Skype secretly monitors users—he hunkered down in his bedroom with his Dell (DELL) laptop. Other academics have known since 2008 that Skype tracks politically sensitive text messages on its Chinese videophone and texting service, known as TOM-Skype, a joint venture formed in 2005 with majority owner TOM Online, a Chinese wireless Internet company. Knockel, a bearded, yoga-practicing son of a retired U.S. Air Force officer, cracked the encryption cloaking Skype’s Chinese service and for the first time identified the thousands of terms—such as “Amnesty International” and “Tiananmen”—that prompt Skype in China to intercept typed messages and send copies to its computer servers in the country. Some messages are blocked altogether.

The lists shed new and harsh light on the surveillance of Internet communications in China. The words subject to monitoring in TOM-Skype’s instant messages, which Knockel updates almost daily on his university department’s website, range from references to pornography and drugs to politically sensitive terms, including “Human Rights Watch,” “Reporters Without Borders,” “BBC News,” and the locations of planned protests. (The system he traced does not involve voice calls.)

For extra credit: Check a current US Skype client to see if similar functionality is present.

(Of course, in the US it might be present but only enabled on those they want to snoop, perhaps after something designed to look like due process ("lawful intercept"), rather than being enabled by default.)

Skype is not very popular in China

Most Skype-like communication is done with QQ in China.

It is also possible to download the english language version
of skype from FileHippo or the equivalent rather than use the awful Tom version of skype.

Actually the Tom version of skype is so bad that most Chinese dont want to use it.

2008. That's pre-Microsoft.

The Microsoft acquisition put the nails in the coffin of dead privacy on skype.

There is nothing strange about having a bar of soap in your right pocket, it's just what's happening.

Actually, I think I remember

Actually, I think I remember reading that the government paid microsoft $4 billion to figure out how to monitor skype in the US because they currently cant do it.

To climb the mountain, you must believe you can.

Brilliant !!!!!!!!

Great Job....Kudo's.....

Can anyone recommend an alternative to skype to block the Multinational surveilenace apparatus ?

The NSA has been doing this with telephones since ECHELON....

just imagine how far advanced they are now, and try to think of a single method of a communication they aren't able to eavesdrop in on.

Aside from writing messages down on paper, or talking away from devices with the ability to transmit audio, there isn't much that anyone could do to evade the NSA.

Although, with so much traffic to monitor, the more advanced techniques are probably reserved for specific targets.

But, it would be a safe bet to say all telephone conversations, texts, and emails are filtered through word recognition software.

The dam on censorship is

The dam on censorship is going to break worldwide. TPTB must be shaking in their boots.

Politicalless Mesh Networks that James Corbett talks about. Very interesting. I think I may just invented a new meme, (PMN).

Microsoft sucks.

Wonder what they're doing to US.

I'd rather be a hungry patriot than a satisfied slave.

kudos

to the kid. that's the one thing that kind of gives you hope these days. to see such bright people uncovering these things.

but it's sad that it's so unsurprising. after Room 641A, and the rest of it.. what is anymore?

Yes, brilliant hacking!

We need guys like him on our side.
