Chapter 311: Hacking

That night, Nanming held a celebration party, everyone gathered together, ate and drank, and had a good time for half the night.

During the dinner, Nan Ming discussed with everyone about investing in Lanshen Special Industries. No one had any opinions, and then he had a brainstorming with everyone for a long time to discuss the next investment, and then waved happily to let everyone go back to rest.

Who would have thought that Su Hongyi would receive a call before he went back, and he was taken aback when he heard the words, and said, "What did you say? Wait a minute."

Su Hongyi walked up to Nan Ming, lowered his voice, and said, "The Institute of Supercomputing called, saying that Qingda Lazy God's load is abnormal, and the network is particularly congested. I suspect it's under attack."

"Attack? What type of attack?" Nan Ming was taken aback, hearing the network congestion, several letters of DDoS immediately flashed in Nan Ming's mind.

"The person on duty said it was probably a DDoS attack." Su Hongyi said.

Nan Ming thought, sure enough.

This afternoon Nan Ming thought about whether someone would attack Lazy God Technology, and it really came tonight.

"Attack?" Yang Ji was startled when he heard these two words, and touched his belt: "Who? Where?"

"It's not that kind of attack, it's a cyber attack." Nan Ming explained.

The so-called DDoS attack is Distributed Denial Service, that is, distributed denial of service attack. To put it simply, it is to control a large number of computers, continuously send requests to a server, keep connecting, and fill the entire broadband with data packets coming and going, so that people who want to visit the website cannot access it.

This kind of attack is simple and rude, and there is almost no good defense method. The only way is to increase the bandwidth.

"Network attack... DDOS?" Zhao Gaofeng and Yang Ji chanted a few words about this, their faces were bewildered, feeling powerless, "Is it a hacker attack?"

"A guy who uses DDOS is not a hacker." Nan Ming curled his lips. Although he doesn't know much about hacking skills and network security, he is also a master in programming after all, and there are still some inferences.

"Don't be careless. If you use DDOS to cover up other attacks, it will be hard to defend against." Su Hongyi said.

"Let's go over and have a look!" Nan Ming tugged Su Hongyi and Han Dongdao, "Everyone who is fine, go back and rest. You all worked hard today."

"How can we leave at a time like this?" Everyone was excited and said they wanted to go and have a look. Even Mr. Jiang and Jiang Chaohua, who were in charge of cooking, both had their sleeves rolled up, feeling like they were going to fight, which made Nanming dumbfounded .

Both Zhao Gaofeng and Yang Ji were holding their belts, feeling uncomfortable. Both of them are security guards, and they always feel that no matter what type of attack, they should follow up.

Today, during the daytime, I just made bold words, saying that I should protect Nanming well, and ensure that no one will hurt Nanming, and I was attacked right now, how can I do this?

A group of people arrived at the computer room, and the operation room was immediately crowded. In the computer room, the teacher on duty and several graduate students were already there. Seeing Nan Ming, he hurriedly said, "Mr. Nan, we are sure that we have been attacked by a DDoS, should we temporarily Offline?"

The so-called offline is to temporarily disconnect the server from the network. Since there is no target to attack, the other party's attack cannot be completed naturally.

Qingda Lazy God does not have any important business that needs to be online.

"Is the other party attacking Qingda Lazy God, or the page of Lazy God Technology?" Nan Ming asked. Some time ago, Lazy God Technology moved the page to Qingda Lazy God, which was done by Su Hongyi.

"Judging from the log files, the attackers targeted Lanshen Technology." The teacher said.

"Sure enough..." Nan Ming frowned, Lazy God Technology is really attracting attention.

Su Hongyi said: "In fact, it is also a way to temporarily go offline with Qingda Lazy God. The page of our Lazy God Technology was originally placed on the rented server. If we go offline with Qingda Lazy God, all attacks will be directed at the original server. When we rented servers, the service providers provided DDoS prevention services, so it was their turn to worry.”

At the beginning, when they bought the service, they bought similar security services. At this time, it is time to enjoy the service.

"How can I do that!" Although he didn't know what was going on, Mr. Peng was upset, "How can you back down after being beaten? Isn't that eggless? No, you have to beat him back!"

"I think so too." Nan Ming rubbed his nose, full of displeasure, what a happy day today, but someone came to make trouble, "If we want to fight back, is there any good way?"

"DDoS is the simplest and most brutal method, and the response can only be simple and rude. They occupy our broadband, and we can only increase the bandwidth." A teacher said.

DDos is like a big panic buying. A large group of customers block the door, making people unable to get in or out. If you want to operate normally, you have to open more doors. You can’t use a machine gun to burst out all these customers. .

This is the most annoying point about DDoS.

"Then increase the bandwidth." Nan Ming said.

The teacher went to contact the service provider. Although it was already night, as a major customer, the service provider quickly responded and allocated a batch of idle broadband to Qingda Lazy God.

And Qingyang University also connected part of other broadband to Qingda Lazy God, and the bandwidth of Qingda Lazy God soon exceeded 10G.

In fact, for an ordinary company like Lanshen Technology that does not provide too many network services, the server only needs 10M, and at most 100M bandwidth is enough. The 10G bandwidth is already a hundred times that of 100M, and a 1.2G movie can be downloaded in one second.

10G, generally speaking, is already the upper limit of the general type of DDoS attack power. If it is just a competitor with a grudge, a boring hacker scattered on the Internet, or other people who do not like Lazy Technology, 10G broadband is enough to accommodate Under their DDoS attack again.

Computers controlled by network hackers are called bots, and most of the controlled ones are servers. If one bot usually has a 10M broadband, to cause a 10G attack, at least 1,000 bots are required, which is already a very large number.

However, the increased bandwidth was instantly filled again.

"More!" Nan Ming frowned.

After a while, the mobilized bandwidth continued to increase, and the bandwidth increased to 100G!

But it's useless, the bandwidth is filled up again in an instant.

"More!" Nan Ming frowned even closer.

The teacher ran to make a phone call, but after a while, he came back with a gloomy face, and said: "The service provider said that they can't add more. It's the peak time of surfing the Internet. If they occupy other broadband, they will be complained." Yes. The service provider suggested that we seek help from the security company."

Qingyang is a non-node city, and its own total bandwidth is less than 700 G. The service provider has allocated one-seventh of the bandwidth to Lanshen Technology, which has done its best.

"I made a fork!" Nan Ming was so angry that he burst out with a foul language. It was not aimed at the service provider. The service provider just helped them increase the broadband, which was already very powerful. He was angry that this was definitely an organized attack.

Attacks over 100G are already very rare.

But now it seems that this number is not the upper limit at all.

"I don't believe it anymore, get them out!" Nan Ming snorted angrily.

"Get it out..." Everyone looked at each other in blank dismay, this is a bit difficult.

At this moment, Yang Ji's phone rang. He answered the phone and said to Nan Ming, "It's Wang Xing, Qing Zhongtang's assistant. He said he has someone who can help."

Yang Ji didn't want Nanming to get in touch with Wang Xing too much, but he couldn't take care of it at this time.

Not long after, Wang Xing rushed over, and at the same time brought a black girl with pigtails.

Hacker TD.

Seeing that it was TD, everyone was quite surprised. They thought that TD had already been arrested or deported. Who would have thought that TD was still in China.

When TD came in, she was still a little excited. Although Wang Xing didn't say it clearly, she also knew that this was where the magical "God's Eye" was. Hearing that the server was attacked, TD immediately volunteered to come. He was even more angry than Nanming and the others in his heart, like an old hen protecting its cubs.

Joke, this is my old lady's "GOD`s EYE"!

This is not the first time TD has come into contact with Qingda Lazy God. She quickly entered the state. She analyzed the log carefully and said to Nan Ming: "The DDoS attack is just a cover, someone is trying to invade."

"Can you catch him?" Nan Ming asked.

"The other party is very cunning and sophisticated. The intrusion was sent from the attacking server. There were nearly 10,000 messages in an instant, and it was difficult to track..."

Nan Ming frowned, and TD hesitated: "I can try, but the probability is too low, unless you can analyze tens of thousands of attacks in an instant, and compare the subtle differences among them, it is possible to find the source."
