20 10 65438+ 10/2 at 7: 00 am, Baidu, the largest search engine in China, was attacked by hackers, and the page displayed after Baidu DNS was tampered with by hackers could not be accessed normally for a long time. The hacker who attacked Baidu this time was suspected to be from abroad and used the method of tampering with DNS records. This is the longest and most serious hacking attack since Baidu was founded. When netizens visit Baidu, they will be directed to an IP address in the Netherlands, and all subdomains of Baidu cannot be accessed normally. [ 1]

It is also known that it is not the first time that Baidu has been hacked. On September 12, 2006, some netizens said that Baidu could not be used normally from that day 17: 30. At one time, the homepage of Baidu website appeared to log in normally, but the speed of searching content was extremely slow. Moreover, this phenomenon also appeared in Beijing, Chongqing, Guangzhou, Changsha and other places. It was not until half an hour later that Baidu's website returned to normal. Since then, Baidu has claimed to have suffered the largest unidentified hacker attack in history. However, it was impossible to visit normally for half an hour at that time, which caused a heated discussion among netizens. Today's incident is the longest and most influential hacking attack since Baidu was founded.

[Edit this paragraph] Behind the scenes

It is reported that Baidu was hacked by a hacker who claimed to be "Iranian cyber army" on Tuesday, and Twitter was attacked a few weeks ago.

When Baidu was hacked, the English words "This website has been captured by Iranian cyber forces" appeared on the homepage of Baidu, and the Iranian flag pattern was also displayed on the black background. In June+February, 5438, Weibo's Twitter homepage was similarly attacked, and anti-American slogans appeared.

Twitter played an important role in Iranian student demonstrations last June, but it is not clear why Baidu was attacked. Experts told Reuters last month that the Iranian government was unlikely to have anything to do with the attack on Twitter. China and Iran have energy trade and good bilateral relations. [3]
