We've found serious vulnerabilities that can be exploited by any web site a user visits with the software installed.

This is economic warfare. The question is which is worth more economically to the US, a connection to China which opens Chinese citizens to the world's press or severing the connection and avoiding any potential complications.
So the question is which one is worth more? Personally im willing to bet that being connected to them is worth more to the US than it is to China.
Last year exports to the USA accounted for about 24% of Chinese exports but only about 13% of USA imports. USA exports accounted for about 6.5% of Chinese imports but only about 4% of USA exports. I wouldn't be so sure about who is dependent on who.
Just in time inventory? Using China as a supplier? Sorry, not happening without a middleman. Shipping isn't reliable enough, unless you are using air and paying out the nose. Unless your JIT means something different to you than to my customers (several my of my customers have NO warehousing space, they need parts for their assemblies when they need them - any earlier and they can't store them, any later and they have a worker doing nothing).
The only reason botnets are so effective is they are distributed. When they come from all over the place, you have to do a ton of individual blocks. If they are all from the same IP space, ok just black hole China's space and that's it. Wouldn't take a block from very many top level providers and they'd be doing nothing at all.
I agree, personally I would worry more about the private key for Windows Update finding its way into the wild. Now that is centralized administrative authority.
Wouldn't it be easy for the people buying the computers to wipe the hard drive and install their own software, without the internet blocking software on it?
For the sake of argument, let's assume this is the case. (And to correct me if I am wrong here.) To be able to block, at the very least the packet header has to be examined. If remote attacker can generate packets faster than you can examine and drop them, you've just been DoS'ed. Multiply the number of packets by the number of computers in China...

You also have to look at the packet header in the course of regular routing decisions. Would it really take more CPU to look at the packet header and drop it into/dev/null than it does to look at the packet header and send it out a different network interface?

The interconnect routers are all using hardware ASICs for their routing. It is absolutely NO problem for a core Internet router to block an entire subnet/country without a single hiccup.

Of course, that morsel isn't for the Chinese people. They could tell their own people "we're creating a botnet to terrorize you", and nothing would happen. In fact, it's for the benefit of people in other countries. Social conservatives everywhere will exclaim "what an excellent goal!"

China further on intruding on its citizens who are already exploited and given no voice is a valid concern -- until it causes the rest of the world the slightest discomfort?
And what exactly would you have the rest of the world do about it? Chinese are already subject to an oppressive dictatorial government, as are North Koreans, Vietnamese, Cubans, Laotians, Burmese, Iranians, Zimbabweans, and in general around half the total world population.
The problem with this paranoia is where does it end. Compilers have known to have backdoors, you can code in assembly but you still need to compile it, what about a backdoor in the BIOS? Hidden microcode in the CPU?
Look, in a "cyber war" you don't fight with DoS attacks, you fight by simply severing the undersea cables. If we were really "attacked" by China this way (which, we won't be, it would end their economy and their leaders seem to be halfway sane unlike that of North Korea) we could simply sever the lines.
Look, in a "cyber war" you don't fight with DoS attacks, you fight by simply severing the undersea cables.
Well, severing the cables would be expensive. More likely we'd just filter incoming traffic from that address space. If every computer in China today started sending a DoS attack at something in the US or Europe, an IT guy would get beeped and would authorize their automated system to blackhole that traffic at the core routers. Basically, it would just cut off traffic originating in China and the rest of us would go on as usual except there would be some interesting network security articles. Heck, with some of the systems in place, companies with regular traffic to china might not even have their normal traffic disrupted since it had been previously mapped out as normal and white-listed.
You don't even need to cut the cables. They have to come out somewhere.. switch the routers off.
If you can't do that, advertise high priority routes so that all traffic to china gets null routed (they can do the same to you, theoretically, if they get in first).
What makes a botnet potentially devastating is that it can create traffic that's indistinguishable from legitimate traffic. When a large enough number of computers from random locations request a page from your webserver, how do you sort the bad requests from the good? It's the slashdot effect on steroids.
If all the traffic was originating from within a particular country, it would be straightfoward to drop that traffic and let other traffic through.
It's interesting to note that in the early days, it wasn't possible to determine geographic location based on IP address. Address blocks were originally assigned rather haphazardly. As the number of networks grew, routers had to store larger and larger routing tables. Eventually this led to a push to reorganize address block allocations in a more hierarchical fashion, which ultimately made geolocation possible.
trusting the chinese government at their word is equally foolish. there are no deep nefarious plots and twisty hidden meanings in this piece of censorware most probably. but at the same time, the chinese government is certainly no paragon of virtue that we should trust is motivated by exactly what they say
not that western nations are any more trustworthy. its just that there is this idiotic notion i often encounter that says "western critics are complaining the chinese have hidden purposes, so since i don't trust western mouthpieces, i'll believe the chinese at their word that they are completely virtuous and innocent in their motivations"
you know, like iran is enriching uranium for peaceful purposes. "that's what they said, that's what i believe. because i won't be a naive idiot for the west. i choose to be a naive idiot for the west's enemies"
hey, here's a radical idea: how about you trust no one and be a naive idiot for no one? that is: distrust the west, distrust china, and distrust iran, all at the same time
DO NOT TRUST THE CHINESE! (But eat their food, wear their clothes, use their electronics) DO NOT TRUST THE USA! (But obey their laws, enjoy their movies, work for their money) DO NOT TRUST THE IRANIANS (But ignore their democratic progress and ignore their people's work for peace)
Here's the real answer: DO NOT TRUST YOURSELF, because you're an idiot.
Distrust is for the weak. Optimistic skepticism and honest effort are for the strong.
Assuming that this is true - all the bots would be contained inside China
If they unleashed the botnet on something outside China
1) Would it not just crush the internal network(s) inside China? 2) Would it not just crush the connections to the rest of the world? 3) Would it not just crush the massive control and filter systems? 4) Would it not just super easy to identify and quarantine?
This reminds me of the 60's when there were actually people who believed that all of those little Japanese cars were programmed to fall apart when a signal came from Tokyo. We'd be stuck with no transportation and Japan would finally win the war.
I'm not saying this couldn't be done with computer software today. But obviously paranoia isn't limited by technology.
"it could build one in "traditional" way using viruses etc."
yea, it's a huge vector for launching a traditional attack though. It hasn't got to go boom on day one, the attack could begin silently by spreading crap slowly over the course of years.
Other than that, I'm guessing Chinese Wikipedians are crapping themselves over this news.
No, all your computer belong to someone who wants to harm China. This is more of a threat to China itself, than anyone else.
From a point of view outside China, this botnet is not distributed. It all shares a few links (possibly saturating them if the botnets gets too crazy), shares netblocks, etc. This botnet isn't capable of doing anything that the Great Firewall operators aren't already able to do.
