Chapter 115 [Encountered traffic attack]

In the past two days, A-shares have gone out of two big negative lines, and they have achieved the title of God K's "whistleblower".

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 head began to silently follow Fang Hong's Weibo account.

As soon as God K closed his position, the market plummeted the next day, and God K entered the market and the market bottomed out.

This is the whistleblower!

Nowadays, almost all major stock forums and exchange groups are discussing. Thousands of stockholders have begun to pay attention to the operations of God K’s ancestors. More and more people are determined. Entry signal.

This sentiment has been continuously strengthened along with K God's continuous and precise bottom-hunting and top-escaping operations, and its influence on the market is also growing.

Correspondingly, the followers of Fang Hong's Weibo account also broke through the 5 million mark in one fell swoop, properly measuring the number one blogger on Weibo.

Attracted a large number of off-site stockholders and netizens to enter Quantum Weibo, and then registered an account to follow the account of K3478. Fang Hong's latest Weibo news has more than 30,000 messages in just two days.

At around 20 o'clock in the evening, Quantum Jump issued another announcement, disclosing the number of users of its Quantum Weibo.

According to the announcement data, as of the release date, the cumulative user registrations of Quandong Weibo exceeded 15 million, ranking first among several similar websites such as Fanfou and Jiwai.

Originally, it may take a day or two to break through 15 million user registrations, but in the past two days, K3478’s precise escape operation has ushered in a wave of fans, directly boosting the number of user registrations on Quandong Weibo .

...

The next day, around 10 am.

Zhuang Youmin, Assistant CEO of Quantum Beat, called Xu Jingren's mobile phone, "Mr. Xu, the website has just been attacked by DDoS suddenly. If it weren't for the DDoS firewall prepared by Mr. Lou in advance, the website may have been down at this moment."

At this time, Xu Jingren was not in the company, but in school.

Hearing the news, his complexion changed instantly, but he quickly realized, and immediately asked, "Have you informed Lou Gaoyuan?"

Zhuang Youmin's voice came from the other end of the phone: "I've already told him, and I'm on my way to the company now."

What is a DDoS traffic attack?

Imagine a scenario where someone from a different number is bombarding you with calls over and over again, and you have no way to blacklist them, and you may end up getting overwhelmed and have to turn off your phone to avoid harassment.

And such a scenario is a common distributed denial of service, that is, what a DDoS attack looks like.

DDoS attacks have existed long before Joe's first iPhone, and are very popular with hackers because they are very effective, easy to launch, and leave almost no trace.

Xu Jingren immediately left for the company, and at the same time ordered on the phone: "Enable the backup network bandwidth immediately."

The network bandwidth directly determines the ability to resist attacks. For example, with only 10M bandwidth, no matter what measures are taken, it is difficult to resist. If the bandwidth is increased to 1000M or even higher, the ability to resist attacks will naturally be greatly improved.

Xu Jingren continued to order: "The backup website is ready at any time. Once the production server goes offline, switch to the backup website immediately."

The function of backing up the website is not complete. If you can achieve full static browsing, you can meet your needs. At the very least, you can also display a notice to tell users that the website is being repaired except for problems.

Zhuang Youmin responded, "Okay Mr. Xu."

After hanging up the phone and rushing to the company, Xu Jingren was also secretly thankful that the boss took precautions and made a series of preparations and rehearsals after being attacked.

Xu Jingren, who was on the way to the company, immediately called Fang Hong again: "Boss, I was really predicted by you. The website is now under attack."

Fang Hong who received the call replied unhurriedly: "It's not a big problem, is it?"

Xu Jingren said in a deep voice, "I'm rushing to the company, and I just learned about it. The specific situation is not clear, but the website hasn't crashed yet, and we are already dealing with it urgently. Fortunately, we have already prepared for it."

Fang Hong replied: "Understood, you can 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.

After all, he is the leader of the team!

Xu Jingren was emotional for a while, and immediately called the company again, and dealt with it immediately when he arrived at the company.

The sudden DDoS attack lasted for more than three hours, but the website never crashed immediately. During the peak period, there was some lag when accessing the website. This was all due to precautions in advance and a lot of money spent.

It is said that the technology is not enough and money is used to make up for it. Quantum Beat not only has technology, but now it is not short of money.

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 the network points to combat some types of DDoS attacks.

After the attack came to an end, Xu Jingren immediately held a meeting to discuss and conclude.

Finally decided to upgrade the host server hardware, and decided to make the website a static page.

Facts have proved that making a website static or pseudo-static can not only greatly improve the ability to resist attacks, but also bring a lot of trouble to hackers.

When a dynamic script must be called, then get it to another separate host, so as not to damage the main server when it is attacked.

In addition, there are a series of other measures, including increasing the number of servers, etc. In fact, improving the ability to resist DDoS attacks is directly proportional to the investment. As long as the investment is deep enough, the ability to resist DDoS attacks can be doubled.

After this unexpected encounter, Xu Jingren paid more attention to the things that Fang Hong had explained before, including the website auditors who also actively expanded the review team to control the community's speech, so that everything could not be published on Weibo.

In the next two days, Quandong Weibo platform encountered more intensive traffic attacks, each time more intense, but still failed to crash the website.

The website was attacked, but Quantum Jump did not make a sound at all, did not report the crime, and did not even publish an announcement that the website was attacked by unknown hackers, as if nothing happened.

For the silent behavior of Quantum Beat, the attackers are a little uncertain about what kind of medicine is sold in Quantum Beat's management gourd.

The key is that several attacks have failed to reach the target, and Quantum Jump has almost no response. This gives the attack the feeling that the other party doesn't take this matter seriously at all, and feels that Quantum Jump is holding back some tricks.

On the fourth day, the attacks stopped abruptly.

Because the abnormal behavior of Quantum Jump makes the attacker a little guilty, no matter how I think about it, I feel that there is something strange in it, and even think that Quantum Jump may be setting a trap. At that time, it will be very passive.

In fact, quantum jumping is simply not responding. This is a strategy given by Fang Hong.

When there is an expected deviation in one thing, people will think more, and will take the initiative to make up for the observed phenomenon and give an explanation.
