Problems with the back door of Qihoo 36

In fact, many software vulnerabilities depend on whether they are handled in time or not. What I know at present is that 36 does open the back door. According to Rising, it seems that it has not been fixed, but I think 36 should be fixed soon if it wants to continue, but as far as we know, it should not be fixed, as long as hackers don't know the data of this back door.

I just read this guy's article and found it interesting. You can copy it and have a look.

The predecessor of p>36 Security Guard

There were only five R&D teams, and 7 million computers (more than 95% of netizens at that time) were "rogue", with an annual net profit of 6 million;

defeated Yahoo, Ma Yun, Baidu, CNNIC and other well-known companies in the industry by spreading rumors, slandering and smearing opponents;

It shows the hypocrisy of "angel investment" to the outside world, but secretly owns the largest forum gunner company in China, and tens of thousands of gunmen turn their opponents from angels into demons overnight;

fabricating lies such as "antivirus companies make viruses" and "antivirus software is free forever" in an attempt to bring "3721 back to life" in the mode of antivirus software;

There are people in the core team who have been condemned by their conscience and left. Zhou Hongyi, the "rogue godfather", is alone.

..... this is Zhou Hongyi and his Qihoo 36, a lean man in the industry who hasn't shown his true colors, and a "Yue Buqun in IT" who is honest and treacherous.

Zhou Hongyi started in 3721 and earned 6 million yuan a year.

In p>1995, Zhou Hongyi graduated from the Department of Systems Engineering, School of Management, Xi 'an Jiaotong University with a master's degree.

In October, 1998, Zhou Hongyi founded the Internet Guofeng Company, whose only product was the 3721 Chinese Internet plug-in which became famous in the industry.

in p>22, 3721 reached its brilliant peak, and the plug-in invaded 7 million computers within one year, with annual income exceeding 14 million and net profit exceeding 6 million. At that year's Spring Festival party, Zhou Hongyi spent a lot of money, spending 2 million yuan, and posted the sentence "It's easier to surf the Internet in Chinese regardless of the willy-nilly" on CCTV everywhere like a dog skin plaster.

In contrast, in 22, Ma Yun's Alibaba, Li Yanhong's Baidu, Ding Lei's Netease and other companies were still on the dividing line between bankruptcy and profit. Even if they made profits, they were only a few million, an order of magnitude less than the profits brought by the rogue plug-in 3721.

In contrast, the anti-virus market in 22 was tepid, and the total net profit of the whole anti-virus industry would not be much more than that of 3721.

3721 successfully adopted virus technology, misleading a generation of programmers.

3721, a plug-in, has almost reached the technical peak. It has gone deep into the bottom of the system, and adopted many ways that viruses may not adopt, such as driving, deformation, anti-unloading, self-protection and hook injection. Even professional programmers are sometimes helpless if they want to uninstall it completely.

At that time, many virus writers praised the driver technology of 3721. Even Jiang Haike (the founder of Antian Lab), who is famous in White Road, wrote an article on why 3721 plug-in is a virus.

It flourished and declined. In the face of the huge profits, the reputation of 3721 was also destroyed to the peak, and its bad reputation even affected the brands of its peers. Some people even put industry leaders like Sina and Sohu in the same category as 3721, calling them "Internet liars and Internet hooligans".

to make matters worse, the money-making effect of 3721 has brought a lot of programmers bad and misled a lot of software. Many authors of * * * software, seeing this bad means of making money, began to learn as usual. Some * * * enjoy software directly bundled with 3721 plug-ins. After installing 3721 every time, I will get a reward from Zhou Hongyi ranging from .3 yuan to 1 yuan.

This way of "earning a dollar" has deeply influenced the atmosphere of the software industry in China from the bottom of the mind. Since then, no one has delved deeply into technology, and no one has studied the needs of users. Instead, they want to "plug in more computers, so that users can't unload them after inserting them, and get more money from 3721".

this example of "bad money drives out good money, and bad guys suffer" made the internet community in China a mess at that time.

3721' s small means, the growth history of defeating Baidu

3721, and the success history of Zhou Hongyi are not only the history of the tears of netizens, but also the history of other companies being oppressed.

Zhou Hongyi uses virus technology to bully users, making it impossible to uninstall; Beating opponents by despicable means, such as smearing, slandering, rumors, etc., is what the period is best at. From Baidu to Yahoo, from Ma Yun, Yang Zhiyuan to Li Yanhong, Zhou Hongyi's underdogs are all defeated.

Baidu and Yahoo became enemies because Baidu has a "Baidu Souba", which is similar to the 3721 plug-in and provides Chinese website functions. Because of this, 3721 mobilized the media and accused Baidu in the media that it could not be uninstalled; Mobilized the forum and accused Baidu hooligans in the forum; Write a letter of exposure to the relevant state agencies, saying that Baidu supports things that are not allowed by the laws of some countries, so that Baidu is often unable to access them.

What's more, 3721 will even release some drivers when it is uninstalled. Its function is only to make Baidu, cnnic and other competitors' products have blue screens, so that users can't use their competitors' products normally.

Next, I'm going to tell a big secret about Zhou Hongyi and the Trojan horse. The value of this secret is enough to shoot one million dollars a week to buy this wonderful head of mine.

Before Zhou Hongyi was forced to leave Yahoo, he used 3721 to do a great thing: he planted back doors, including DLLs and drivers, on users' machines through 3721 clients all over the country. The password to open this back door is only known to Zhou and several core technicians.

This is the biggest reason why Qihoo 36 can make users feel particularly easy to use as soon as it is launched. Because the Trojans it killed were all planted by itself with the 3721 client.

if you plant it yourself and kill it yourself, the effect will be excellent.

In order to maintain the reputation of Qihoo 36, Zhou has been doing such things: constantly making Trojans and rogue software, and then constantly killing them.

Do you still remember the hooligans that 36 Security Guard killed when it was first launched?

among the five hooligans, Yahoo Assistant, 3721, Baigou Plug-in (Wulin List Company), dudu Plug-in and 9991.com

, Yahoo Assistant and 3721 were created by Zhou himself. Hundred Dogs was invested by Zhou, and 9991.Com was launched by Zhou through 3721. Only dudu plug-in is the work of Chen Yizhou.

Of the five hooligans, Zhou Hongyi created four by himself, which really deserves the title of "godfather of hooligans".

Zhou Hongyi's search dream is broken, but he has no choice but to bet on free antivirus

Since he was forced to leave Yahoo in 25, Qihoo in Zhou Hongyi has gone through four years in 28.

In four years, Zhou Hongyi only did one and a half things. One thing is: it proves that the so-called community search is not feasible, and the $5 million raised at the beginning is in danger of being wasted.

The half thing is that, inadvertently, Qihoo 36 security guard, the illegitimate child of 3721, took root and deceived the sincere support of tens of millions of users across the country. By 28, the shareholders, big and small, who had invested 5 million dollars at the beginning, had given up hope for the success of the search and put a lot of pressure on Zhou to get their investment back.

But as we all know, money is easy to spend, and it is as impossible to get it back as it is to make sperm spots on condoms become babies. But Zhou Hongyi must give the shareholders an explanation. What should we do? He set his sights on the anti-virus industry.

There are only six major manufacturers in the antivirus industry: domestic Rising, Jiangmin and Jinshan, and foreign Norton, Trend and Kaspersky. Norton and trends have negligible influence in the personal market. Therefore, Zhou Hongyi's opponent this time is Ruijin Jiangka.

among these four manufacturers, Mr. Wang Jiangmin focuses on real estate. As the saying goes, if a bird hangs a house on its wings, it can never fly again. What's more, Mr. Wang has dozens of properties in prime locations in Beijing. Antivirus is just Wang's hobby.

Jinshan, although it has been listed, its executives have fled, like flying swallows, and its fighting capacity has almost been reduced to a cottage gathering righteousness. Although Kaspersky has a strong momentum, he is an outsider after all, and his strength is limited.

At present, Rising, which occupies the largest market share, is short-sighted and "steady" in style. To be honest, some of them are short-sighted and do not want to make progress. Looking up and down, looking left and right, these four opponents are really not bullying, and some of them are sorry for their conscience.

if we can take all the profits of the anti-virus industry, we can also be worthy of the shareholders of $5 million.

Anti-virus industry "stirred up the excrement stick", tens of thousands of gunmen and four rumors attacked the anti-virus giants

The past facts have proved that wherever there is Zhou Hongyi, there are rivers and lakes; Where there are rivers and lakes, there are all kinds of rumors, disputes, smears and slanders. As Mark Twain said in Running for Governor, your loyal friend, who used to be a decent man, has now become Mark Twain, a perjury, a thief, a corpse kidnapper, a drunkard, a briber and a blackmailer.

originally, the anti-virus industry was the only remaining software field in China. With the help of relatively high technical threshold and grasping the needs of localized users, China antivirus software industry has resisted the attacks of international giants such as Symantec, Trend and Microsoft. Jinshan Jiangmin Rising, despite all kinds of minor faults, is essentially a good national enterprise, which guarantees the independent intellectual property rights of the anti-virus industry, contributes tax revenue to the country and brings security to users.

in 8% countries in the world, anti-virus software has been monopolized by international giants. In this case, the persistence of Jiangmin Jinshan Rising, to some extent, has become a symbol of domestic high-tech industry. Because of them, China IT industry has not completely become the lowest part of the international industrial chain.

If I were asked to score three domestic antivirus manufacturers, they would get 8 points, although they didn't get 1 points. After all, this is China's own company! But these enterprises, under the attack of Zhou Hongyi, have become "shameless thieves, liars and gangsters".

for CNNIC, the means to deal with it is simpler. Zhou Hongyi declared in the media that "CNNIC is a swindler organization that pulls the tiger skin of the government to bully small enterprises"; Using the media, rumors and technical means of Gunman Mountain < P >, both Baidu and CNNIC were beaten to pieces.

Rogue 3721 sold for 1 billion RMB, and Zhou Hongyi undercover Yahoo staged Infernal Affairs.

In p>23, the word of mouth had sunk to 3721 in the 18th floor of hell, and it had become a hot potato in Zhou Hongyi's hands, which made it impossible to get on the market (American law was not fun), and the income was decreasing (netizens were maturing). As a result, a "white idiot" appeared at this time, and Yahoo USA spent $12 million to acquire 3721 and reorganized it into Yahoo China Company.

according to the exchange rate at that time, the price was almost RMB 1 billion.

Zhou Hongyi wanted to take this opportunity to repackage himself and become a respected "Internet leader". Who knows that the headquarters management of Yahoo in the United States is extremely strict, and it is not given the opportunity to play at all. As a result, I had to leave Yahoo a year later.

this departure was not in vain. In advance, Zhou Hongyi has made many related contracts, sent his confidants to Yahoo USA to learn the core technology of Yahoo search, and took away a large number of resources from Yahoo, including talents, contracts and everything.

At that time, google was in full swing, and Baidu had just gone public. Zhou Hongyi left Yahoo with joy and really wanted to build his own search empire. To do great things, of course, you need money! Search is an industry that eats money. Microsoft invested $5 billion and didn't even hear a sound.

Raising funds has become a top priority for Zhou Hongyi. Because of his unhappy departure, Yang Zhiyuan even threatened to "ban Zhou Hongyi in VCs all over the world". And Zhou Hongyi himself only has the money to sell 3721, so doing search is really a drop in the bucket.

So, Zhou Hongyi thought of a way, and declared that "do community search, cut into search from market segments, and build a new google".

I have to say, this slogan is very tempting. Zhou finally got 5 million dollars from VC such as Sequoia Capital, and a brand-new brand "Qihoo" opened.

This is the past life of the so-called "Qihoo 36". Although Zhou Hongyi cheated countless VCs and ignorant netizens MM with the help of the title of "angel investor", his "rogue godfather" stinks. In the words of Qi Xiangdong, president of Qihoo, "You have been a rogue once, and you will always be a rogue in this life".

Of course, this sentence was scolded by Qi Xiangdong. Because now 3721 has been sold to Yahoo China ... which is a subsidiary of Jack Ma.

qihoo 36 massacre 3721 Zhou Hongyi turned against Yahoo

Zhou Hongyi wants to do "community search", but the technical threshold required for search is very high. What should he do?

Of course, the rogue godfather remembered the method he relied on to succeed: IE plug-in. However, this time, his method is more subtle and more confusing to netizens. He made an "enhanced version of 3721", which was later 36 security guards.

in p>26, the internet in China was in complete darkness. The rogue software headed by 3721 made a lot of noise. The endurance of netizens has also been pushed to the limit. At this time, Zhou Hongyi's Qihoo appeared as a savior: he released Qihoo 36 security guards. The core of developing this thing is the core team that once wrote the 3721 plug-in, and the backbone of this team once went to Yahoo USA for further study on driver-level plug-in writing technology.

God can personally destroy the human beings he created, and the founder Zhou Hongyi certainly has the means to destroy 3721. At this time, the 3721 has been completely sold to Yahoo. After killing it, it can bring honor to itself, and it can also hit Yahoo Yang Zhiyuan's China strategy and avenge himself on the fire.

Sure enough, the new rogue king easily killed the old rogue king. 3721 Plug-in and Yahoo Assistant, two rogue softwares owned by Yahoo (sold to them the week before), were killed. Based on the simple theory that "the enemy of my enemy is my friend", many netizens are confused and regard 36 security guards as gods, completely forgetting that it is just a new generation of hooligans born out of 3721.

I'm not biased in saying this. If you don't believe me, please read the manual of the 3721 plug-in 25. One of the functional instructions clearly says:

"Thoroughly kill 3878 malicious scripts and 12 selected popular Trojans!"

think again that 36 security guards have been using
