Baidu Suddenly Hit by a Frenzied Attack, Search Engine Stages a Hacker Empire - China DOS Union Forum

News flash:

Beijing Morning Post reports: without netizens noticing at all, China's Internet industry had actually just gone through the largest hacker attack in history, and the target was Baidu, the world's largest Chinese search portal. Fortunately, after a bitter fight lasting more than 60 hours, the hackers have temporarily called it off.

裁刘建国 introduced to reporters the "tragic" offensive and defensive battle at the time. It is reported that after 10 p.m. on May 15, the search volume of ｂａｉｄｕ．ｃｏｍ suddenly surged, with the same word being searched as many as 38863 times, and there were thousands upon thousands of similar malicious query requests. In a short time, Baidu's bandwidth consumption had shot up by more than 25% over normal levels. After receiving the system alarm, Baidu engineers discovered that most of the similar queries came from the IP address of the same partner. "In the system, each of Baidu's search partners has its own identifier, like a pass. After investigation, the hackers had obviously exploited a program vulnerability on one client's side, and only by using a 'forged' pass were they able to charge straight in." With the partner's cooperation, this kind of "wolf in sheep's clothing" attack stopped at around 4 p.m. on May 17, but at that point the hackers completely tore off their masks and began close combat. A huge number of pointless searches still came in overwhelming waves, and Baidu was forced to dispatch dozens of engineers to respond in order to maintain normal system service. It was not until the afternoon of May 18 that the hackers' attack was completely beaten back.

This was a typical "distributed denial of service attack," aimed at exhausting system resources; this method of attack had previously even caused the global Internet to fall into paralysis for a time. According to Liu Jianguo, this attack lasted for more than 60 hours in total, with the number of attacks reaching as high as 1000 per second. Its duration, sophistication, and ferocity were all rarely seen in China. It is said that an ordinary hacker attack reaching 100 times per second already counts as a "strong attack."

Since most domestic websites are Baidu's partners, once this hacker attack succeeded, it would cause enormous trouble, because information searching has always been one of netizens' main needs online. According to a preliminary investigation, the IP addresses used in the later stage of the hackers' attack came from Britain and Spain. Were they foreign hackers, or was the attack routed through foreign countries? The relevant parties are still investigating further.

I don't love Baidu, but I don't want to see it go down!

I think Baidu is very easy to use; for Chinese searches it's better than GOOGLE
