In the past two days, the A-share market has seen two big negative lines, earning the title of "whistleblower" of God K.
Now it is really enough to affect A's market sentiment, because more and more retail investors are following Fang Hong's account, and the A-share market is mainly composed of retail investors.
Even the village chief began to silently follow Fang Hong's Weibo account.
As soon as God K closed his position, the market plummeted the next day. When God K entered the market, the market bottomed and went up.
This is the whistleblower!
Nowadays, almost all the major stock forums and exchange groups are discussing. Thousands of investors have begun to pay attention to the operations of the founder of K God. More and more people are convinced that K God's closing a position is a signal to run away, and K God's opening a position is a sign of running away.
Entry signal.
This sentiment continues to intensify with K God's continuous and precise operations of buying bottoms and escaping from tops, and its influence on the market is also growing.
Correspondingly, the number of followers of Fang Hong's Weibo account also exceeded the 5 million mark, making him the largest blogger on Weibo.
It attracted a large number of off-site stock investors and netizens to join Quodong Weibo, and then registered accounts to follow the account k3478. Fang Hong’s latest Weibo news received more than 30,000 messages in just two days.
At around 20:00 in the evening, Quantum Beat issued another announcement, disclosing the number of users of its Quantong Weibo.
According to the announcement data, as of the release date, the cumulative number of registered users on Quodong Weibo exceeded 15 million, ranking first among similar websites such as Fanfou and Jiwai.
Originally, it might take a day or two for the number of user registrations to exceed 15 million, but in the past two days, k3478’s precise top-escape operation has ushered in a wave of rising fans, which directly pushed up the number of user registrations on Quantong Weibo.

…
The next day, around 10 a.m.
Quantum Beat CEO Zhuang Youmin's call came to Xu Jingren's mobile phone, "Mr. Xu, the website just suddenly suffered a DDoS attack. If it weren't for the DDoS firewall that Mr. Lou had prepared in advance, the website would have been down at this moment."
At this time, Xu Jingren was not in the company, but at school.
Hearing the news, his expression suddenly changed, but he quickly reacted and said immediately: "Have you notified Lou Gaoyuan?"
Zhuang Youmin's voice came from the other end of the phone: "I've told him, and I'm on my way to the company now."
What is a DDoS traffic attack?
You can imagine a scenario where someone is bombarding you with calls over and over again using different numbers, and you are unable to blacklist them. Eventually, you may become unbearable and have to turn off your phone to avoid harassment.
And such a scenario is what a common distributed denial of service, that is, a DDoS attack looks like.
DDoS attacks have existed long before Qiao Bangzhu launched the first iPhone, and are very popular with hackers because they are very effective, easy to start, and leave almost no traces.
Xu Jingren immediately left for the company and ordered on the phone: "Enable backup network bandwidth immediately."
Network bandwidth directly determines the ability to withstand attacks. For example, if the bandwidth is only 10m, it will be difficult to resist no matter what measures are taken. If the bandwidth is increased to 1000m or even higher, the ability to withstand attacks will naturally be greatly improved.
Xu Jingren continued to give instructions: "The backup website is ready at any time. Once the production server goes offline, switch to the backup website immediately."
The functions of the backup website are not complete. If it can be fully statically browsed, it can meet the demand. At the very least, it can display an announcement to tell users that the website has no problems and is being repaired.
Zhuang Youmin responded: "Okay, Mr. Xu."
After hanging up the phone and rushing to the company, Xu Jingren was secretly glad that his boss had nipped in the bud and made a series of preparations and rehearsals after being attacked.
Xu Jingren, who was on his way to the company, immediately called Fang Hong again: "Boss, you really predicted that the website is now under attack."
Fang Hong, who received the call, replied calmly: "It's not a big problem, right?"
Xu Jingren said solemnly: "I am rushing to the company, and I have just learned that the specific situation is not clear, but the website has not crashed yet, and it is already being dealt with urgently. Fortunately, we have been prepared."
Fang Hong replied: "I know, you can just deal with it."
The call ended quickly, and Xu Jingren found that the boss was really calm, as if this matter was nothing at all.
He is the leader of the team after all!
Xu Jingren sighed for a while, and immediately called the company again. He rushed to the company and dealt with it immediately.
This sudden DDoS attack lasted for more than three hours, but the website never crashed immediately. During the peak period, there were some lags when accessing the website. This was all due to the precautions taken in advance and the considerable expenditure of money.
There is a saying that money is not enough to make up for the lack of technology. Quantum Beat not only has technology, but also money now.
The company's network equipment will not become a bottleneck. Routers, switches, hardware firewalls and other equipment are all good products. Now it is necessary to have a special relationship or agreement with the network provider. If a large number of attacks occur, please contact the network provider.
It is very effective to limit the traffic at network nodes to combat some types of DDoS attacks.
After the attack came to an end, Xu Jingren immediately held a meeting to discuss and summarize.
Finally, I decided to upgrade the host server hardware and also decided to make the website a static page.
Facts have proven that making a website a static page or pseudo-static can not only greatly improve the ability to resist attacks, but also bring a lot of trouble to hackers.
When dynamic script calls are necessary, move it to another separate host to avoid compromising the main server in the event of an attack.
In addition, there are a series of other measures, including increasing the number of servers. In fact, improving the ability to resist DDoS attacks is directly proportional to investment. As long as the investment is deep enough, the ability to resist DDoS attacks can be doubled.
After this unexpected encounter, Xu Jingren became even more concerned about what Fang Hong had explained before, including the website auditors who also actively expanded the review team to control community speech and not publish anything on Weibo.
In the next two days, the Liangdong Weibo platform encountered more intensive traffic attacks, one after another, but it still failed to crash the website.
The website was attacked, but Quantum Beat remained completely silent, did not report anything, and did not even issue an announcement that the website had been attacked by unknown hackers, as if nothing had happened.
Quantum Beat's silent behavior makes attackers a little unsure about what medicine Quantum Beat's management is selling.
The key is that several attacks failed to reach the target, and Quantum Beat had almost no response. This gave the attack the feeling that the opponent did not take the matter seriously at all, and it felt like Quantum Beat was holding back some moves.
On the fourth day, the attack suddenly stopped.
Because the abnormal behavior of Quantum Beat made the attacker feel a little guilty. No matter how he thought about it, he felt that there was something fishy in it. He even thought that Quantum Beat might be setting up a trap. As the saying goes, there must be a monster when something goes wrong. He stopped because he was afraid of overturning. Once he was dug out,
It will be very passive at that time.
In fact, quantum jump is simply no response. This is a strategy given by Fang Hong. It can be said that there is no trick to win. In fact, it takes advantage of human nature's tendency to be smart and anxious about the unknown.
When something deviates from expectations, people will think more and take the initiative to make up for the observed phenomena and give explanations.
