Academics, Activists Breaching China's Firewall
(old news - 08:19AM Tuesday Jul 04 2006)
tags: security · world
The Chinese government's tight rein on a free internet is well known. All traffic coming in must pass through one of nine gateways where routers scan for content. But an increasing number of academics and activists are finding ways to broach China's sophisticated firewall. Academics at the University of Cambridge have not only found a way in, but to also launch denial-of-service attacks using the firewall itself. "Due to the design of the firewall", explained Richard Clayton, "A single packet addressed from a high party official could block their Web access." Meanwhile, in California, an eclectic band of activists attempts to place circumvention technology into the hands of Chinese web surfers. In besting the Chinese firewall systems one activist observed ""We have to outrun them with better technology. And do it very fast." Bill Xia, CEO of Dynamic Internet Technology Inc, also chronicles his battle against internet suppression. Says Xia, I believe that information -- that the truth -- can change China.

Re: broach

v., breached, breach·ing, breach·es.

v.tr.

1. To make a hole or gap in; break through.
2. To break or violate (an agreement, for example).

*shrug*

The first definition does make more sense, true, but...
#5 of your definition of broach would make sense: the hole is already there, we're just making it larger (tool is irrelevant, this isn't literal, it's an expression.)

Too bad China has no intention of stopping all the spam & illegal activity coming from their country. I hope they continue to be breached, they deserve it. They are a country run by hypocrites.

Academics beat firewall & then tell China how

»news.com.com/Academics+break+the···437.html
Clayton, speaking at the Sixth Workshop on Privacy Enhancing Technologies in Cambridge last week, said that the researchers had reported their findings to the Chinese Computer Emergency Response Team.
So the researchers figured out how to beat China's firewall, then promptly told the Chinese government how they did it. China can now plug that hole. Seems like they did China a favor, but are still trying to claim kudos for beating the bad guys. Sounds kind of hypocritical to me.

Right on, TKjunkmail. It is pointless to find a weakness against your enemy to exploit, and then go tell it to the enemy or someone closely related. Pathetic

Just wait

If these dissidents based in the US actually become moderately effective, look for the folks to be prosecuted by the US Government, especially if the Chinese Government complains.
Wouldn't want to PO the Chinese government since so much of US Corporate profits are tied up there. The Chinese government would simply complain to the government that hacking attacks are being made from within the US (which is under current US law illegal). We've already seen US Corporations roll over and comply with Chinese censorship requirements in their pursuit of the Almighty Dollar (or the Almighty Yuan).

And how many times does the Chinese government take action against their people when the U.S. finds them spamming or hacking us? I don't think it's often.

You are talking about two different things what the hackers do here is against US law while what they do there may not be against Chinese law, thus no reason for prosecution.

Slightly different, but in the same vein -

A large proportion of pirated media comes out of China. MS, the RIAA & the MPAA have complained loudly about this for years. It's against Chinese law. But all the do is say 'how dreadful, this must stop' - yet nothing is done. Yet now they are complaining that that piracy of media [produced in China] is hurting their own industries.

Again, I have seen [here at BBR & other places] that many hacking and DOS attacks originate in China. It's against Chinese law. But again, all the do is say 'how dreadful, this must stop' - yet nothing is done.

Why? Because trade relations with China are more important to the US then the RIAA's pirating concerns.

While I agree with you in principle you would also have to say that some of the money from the pirates is going into the right pockets. Payola knows no ideological bounds.

Trade relations with China are more important to China then the US. While it would suck to have to pay twice as much for my shirt, the Chinese economy would go down in smoking flames without the US consumer. Also a good proportion (textiles, manufacturing, Agri) of the US would be VERY happy if Chinese trade relations soured. In fact up until the end of last year the Senate was talking about a 27.5% tarriff on all imported Chinese goods if they didn't start allowing their currency to appreciate.

China won't do anything to sour their trade relations, and our government certainly doesn't support the censorship/human rights issues they practice over there.

While what China is doing is wrong, I hate to see US Gov't resources going to help the Falun Gong, a religious cult that doesn't deserve any help at all. If the US is going to figure ways to beat Chinese firewalls for VOA or CNN then fine. But let's stay out of taking sides with this nut group. »en.wikipedia.org/wiki/Falun_Gong

Depending on your perspective and experiences any religious group can seem like a nut group to someone. I though don't see it.

Help that the US gives any nonviolent group that helps bring freedom and liberty to China, I think is a good thing.

"helps bring freedom and liberty to China"

Once that happens that just means more of my money will go to support China. Why must everyone look to fix other countries problems when America has enough of its own problems that are being ignored?

Hmmm, seems harmless enough. If they were a Christian, Muslim or other religious group being suppresed, should the US take sides?

I just want to clarify that Falun Gong is not a "nut group" as this poster says. I've been practicing Falun Gong for 9 years here in the U.S. and have benefited tremendously from it (i.e. better health, less stress, etc.)

Falun Gong practitioners have been using their own personal resources to counter the persecution which has been waged against them since July, 1999. Breaking through China's internet firewall is one way of bringing the truth to millions of people there who would otherwise not have access to free media.

BTW, I am a normal Caucasian American, raised in a middle class suburb, and educated (Master of Science in Electrical Engineering). Most of my fellow practitioners of Falun Gong have either Master's or PhD degrees.

A free China will make this world a better place for all. Happy Independence Day!

Well, Falungong is not even a religion. It is just that its founder is to be treated like God. I wouldn't be surprised if Falungong is just another group secretly funded and trained by the US government just like Al Quaida.

Some of this make little sense!

OK, so we have a stateless firewall that just fires additional RST packets to both ends if a packet contains specific keywords.
These RST packets can be easily filtered, e.g. even with a last century vintage ZyXEL P310 router containing a RST bit specific generic packet filter, and then the rest of the connection can go on just fine.

The reason the Chinese use this relatively dumb method is the fact that due to the huge traffic volume at these choke-points any attempt for a real stateful inspection would require orders of magnitude more computing power.

However, the discussion of the possibility of using this for DoS attacks makes very little sense. You cannot just forge some packets to send a RST to some arbitrary computer and then expect to cut off its internet access. Last time I checked, RST packets are specific to an ongoing existing connection and only that specific connection can be killed, and only if everything (source and destination ports, etc.) matches up. Typical outgoing connections have random source ports, so it there is only a minuscule chance to get it right.

And why would it kill all communications for up to one hour? Didn't we just read that the firewall is stateless? Killing future connections between the same endpoints would require a state table, something we were just told does not exist. If it would exist, the RST filtering would not work anyway, right? (see above).

Those "academics" and "activists" better make damn sure they know what they're doing and make the risks crystal clear for those people in China who risk life imprisonment or worse.
