We are under attack
We are under attack and we need help.
Likely in response to a recent story in the Wall Street Journal (WSJ), we’ve experienced our first ever distributed denial of service (DDoS) attack. This tactic is used to bring down web pages by flooding them with lots of requests - at the time of writing they number 2.6 billion requests per hour. Websites are not equipped to handle that kind of volume so they usually “break” and go offline.
This kind of attack is aggressive and is an exhibition of censorship by brute force. Attackers resort to tactics like this when they are left with no other options.
We are not equipped to handle a DDoS attack of this magnitude and we need help. Some background:
-
The attack started on March 17 and we are receiving up to 2.6 billion requests per hour which is about 2500 times more than normal levels.
-
This attack affects all of our mirror websites. While we have talked openly about our method of using collateral freedom to unblock websites and mobile apps that have been blocked by the Chinese authorities, the WSJ story clearly stated how the strategy works and how it is being used successfully to deliver uncensored content into China. Blocked websites that we have liberated in China include Boxun, Deutsche Welle and Google.
-
We don’t know who is behind this attack. However, the attack coincides with increased pressure on our organization over the last few months. The Cyberspace Administration of China (CAC) publicly called us “an anti-China website set up by an overseas anti-China organization”. We also know that CAC has put pressure on our IT partners to stop working with us. Recently, we noticed that somebody was trying to impersonate us to intercept our encrypted email.
-
Last week, Reporters Without Borders, an NGO based in Paris, used our open source method of collateral freedom to unblock nine websites around the world, including two of importance to China: Mingjing News and The Tibet Post.
We need your help in the following areas:
-
Because of the number of requests we are receiving, our bandwidth costs have shot up to USD $30,000 per day. Amazon, which is the service we are using, has not yet confirmed whether they will forgo this. If they do not forgo this, this will put a significant squeeze on our operations.
-
We need companies like Amazon to be on our side and, more importantly, on the side of freedom of speech. We need you to tell Amazon that you think that freedom of speech is an important issue and that Amazon, as a leading global enabler of the internet, plays an important role in access to information.
-
We’ve upgraded to faster servers and used other techniques to manage the load and it’s working for now but we fear that the attack may be intensified at any time. We need help to manage this. If you have expertise in this area, please contact Charlie Smith or ping us via Twitter.

You deserve that for been criminals to the free Internet.
Regarding the DDoS attack - please consider using Cloudflare as a caching layer for your website - they are good when it comes to defending against that sort of attack.
+1 you should sign up to Cloudflare. Let them soak up the attack so you only pay for legit requests.
If you use CloudFlare you'll have to release all your current AWS public IP's and get new ones. Also AWS does give you a layer of protection but it is manual and maybe hard to maintain if the DDoS is from zombies or botnet.
For instance, CloudFlare has a program specially for website that empower freedom speech and I think it won't cost you a penny.
Please sign up for CloudFlare. Even at $200/month you will get significant benefits and DDoS protection, they are REALLY good!
+1 for CloudFlare
这种ddos是对着url进行攻击吧。。amazon的url感觉都是随机生成的,写个api一小时生成一个新的url。。如果是自动抓取就像上次干掉全国dns那样把攻击引导百度cac。gov.cn之类的吧。。。(没用过amazons3不清楚能不能换url)
Sent you an email, let me know if you need help setting Cloudflare up. If nothing else it's a great place to start.
You should look at CloudFlare. They are quipped to handle this sort of thing and they are definitely less than $30k per day!!!
Cloudflare is 'throttled' in China as with all the other CDN's.
Any requests to a CDN based resource are effectively denied.
Think again.
Cloudflare IP addresses is completely blocked in China. Using CF is not a good choice at the moment.
Create an Avaaz campaign to help support your conversation with Amazon? Might be easier than Twitter for a lot of your readers.
Consider deploying on premises protection to defeat the attack at the very edge of your network. @Corero allows for good traffic to pass, while mitigating the DDoS attacks in real-time.
Time to start naming names.
The president of China is Xi Jinping and everyone should know his name. Nothing in China happens without his consent.
Xi Jinping, Xi Jinping, everytime you hear about censorship in China you should think of Xi Jinping. Everytime you write about censorship in China you should make sure and write his name, Xi Jinping.
Rant over, start naming names people.
Use Fail2ban. No cost, easy to load and protects against several forms of attacks. http://en.wikipedia.org/wiki/Fail2ban
You can get a similar effect to Cloudflare (unfortunately minus the benefit of their massive infrastructure to absorb traffic) if you install mod_evasive (Apache module) and tune your config a bit. See the DDOS section in the included link, specifically lowering your timeout and keep alive timeout. Also turn down MaxRequestWorkers if your server is spawning too many processes. With mod_evasive, specify the DOSSystemCommand to ban the address using your firewall, for example, with iptables something like:
iptables -A INPUT -s %s -j REJECT
mod_evasive will substitute the %s for the source IP.
Check out:
mod_evasive: https://www.linode.com/docs/websites/apache-tips-and-tricks/modevasive-o...
Apache config: https://httpd.apache.org/docs/trunk/misc/security_tips.html
consider moving your hosting to ovh or online since they do not limit you on traffic. and they are cheap. and they offer the best ddos protection there is!
You may consider explaining to amazon that you are under attack and want the traffic dropped upstream.
Amazon should be able to do better than letting the host application absorb the requests (If they can not, I am rather disapointed).
Kim John Coon's suggestion above to try and identify and filter the abusive traffic with iptables will help take the load off your server.
安装360的用户普遍感觉电脑变慢,天下有免费午餐吗,360有可能利用用户电脑进行云计算或者ddos攻击
I see that the effected services have been blocked to those outside mainland China. Good move to counter this attack, well done.
Time to start naming names.
The president of China is Xi Jinping and everyone should know his name. Nothing in China happens without his consent.

Just get a firewall. Cisco if it's that bad. Or just use a dedicated ESF server for you're public ip and you'll be protected and it's got a very fast learning curve. We've been fending of attacks every minute from around the world with ESF. You'd be surprised how good this FW is and you don't even need a license.

now we are under attack in AU
blocking, dns fudged to show fake errors, searchines and those widgest they have on so many other websies suddenle become full of outright malicious code .. and that gets worse and worse, even the operating systems (all of them) spit out fake error messages ... some stuff like that even in linux source code .. all operating syste, agffected and the symptoms are the same .. files mysteruiously get deleted (even text files and code), sites get blocked and things reguce to cionnect to local networks unless that is connected to to the outside .. everything suddenly wanting centralised "cloud" logins, and a lot of nasty code snuck into operating syustem updates .. seems like in the last month or so its suddenly malware everywhere on EVERY OS ..
and try searching for a clan install iso of anything and you are quickly under attack from just about everything out there ... ... seems like not just one corrupt corporation but a consortium of the most corrupt corporations on earth and ALL of it seems to be trying to bully people into handing over admin of their OWN pc to unknown third parties i"in the cloud"
THERE IS NO WAY IN HELL I AM GOING TO TRUST SUCH OBVIOUSLY CORRUPT COMPANIES AND NO WAY IN HELL I WOULD TRUST SOMEONE TRYING TO FORCE ME TO TRUST THEM..
"management" stops at the front router .. that the way it will STAY ..
do not EVER give in to those creeps - DO NOT BUY THEIR STUFF - make sure everyone knows
yes it IS getting into OS updates ..
in open source systems have a look! .. thetre are error messages designed to MISLEAD the users - obviously something malicious got in .. and where theres no siource code the effect is the same top - its in EVERYTHING that was updated over the last couple of months.
now the government here even officially passed a bill to fo censorship! .. and its happening all over the world .. same stuff about "metadata retention" .. and they talkk about usage data.. NO - its obiously a LOY more than that if they are putting code on every user pc, deleting their data witrhour warning, and even the error meressages lie and every attempt to get rid of it by trying to find a frees clean distro iso met with attack after attack .. javsript everwhere not just tracking bout way more malicious .. attacks from every direction .. never seen anything this bad... and anty info seems impossible to find ..
censorship everywhere
never would have thought it woyuld become like that over here.. but looks like the same talk from politicians, the same trolling and sloganising from corporations
probably not hard to giess what went on atr those secretive "trade talks"
this looks like planet scale totalitarism .. corruuption fgone mad ..
isd there anything left that is safe? .. how will anyone be abloe to da anyithing if you don;t know id that file will get deleted just after you save it!!!!
and its obviously for censorship , not "copyright" or any other broken nonsense .. whate else could it be if text files and code set it off even more than music or video and it doesn't seem to care whether you made it.
seems like its the worse malweare ever seen coming from every directopm at the same tind along with it a lot of suspicious trolling and "social engineering"
all I can find is the occasional leftover hint ... news items explaining anything rare (probably censored)
MAKE SURE THEY DON:T GET A SINGLE CENT.
it looks like a consortium f the most corrupt corporations on earth have been changing the law in every counltry precendent by precedent over the last decade and syicking their dirrty fingers into everything.. not it sems the have a leash on nearly every government and their security agencies .. the most corrupt corporations on earth - and those obvously stacked meetings of so called "standards bodies" in recent years .. yes they are even hijacking network protocols...
.. probably not hard now to guess what went on in those secretive talks .. with all that happening since then
no MANAGEMENT STOPS AT THE FRONT DOOR AND THERE IS NO WAY IN HELL I WILL LET THEM GO ANY FURTHER.
what sort of idiot would want to trust lowlife like that with anything?
by now they should know what I think if their "cloud" bullshit!
no .. no way
I would want let third party "management" run by people so corrupt near any box let alone break things, delete data and try to destry my life! .... I will fight in anyt way I can to keep those
creeps out.
it might help if there was a still a way to communicate with anyone without anything important or even slightly interesting disappearing .. but nonetheless they are not getting in my jouse .., I never wanted to be anyones enemy and won;t be selling out to their ways and hurtunbg anyone .. but I sure as hell won;t lert them control anything here!
so angry I can barely type...
don;'t want to even think about what other people might do .,.
no i despite how bad the furureits looking I just won;t put up with it ..
btrining that inot my house makes it *personal* and we must make sure EVERY company or person who helped them attack us NEVER EVER gets a cent out of ANYONE
yes - Im angry..
intersing though - if this were a file on my h
no i despite how bad the furureits looking I just won;t put up with it ..
btrining that inot my house makes it *personal* and we must make sure EVERY company or person who helped them attack us NEVER EVER gets a cent out of ANYONE

and I never try to hurt anyone.. I'm actually still human, unlike those creeps
