Chapter 211 Lessons (1 update on the 2nd)

The female employee of the customer service department, dressed in O-suit, handed the information in her hand to Li Shoufeng's table, then took two steps back, with a slight uneasy face, as if she was afraid that he would take his anger on him.

When Li Shoufeng saw the content on the paper, he raised his eyebrows, slapped the table with his palm, gritted his teeth and said, "Arrogant, too arrogant!!"

It turned out that the piece of paper was a message from the official anti-terrorism forum with the title "Disconnection notification". The content was very simple, with only one line of words, "The entire anti-terrorism online will be restarted at 15 o'clock, and all online players will be disconnected. Here is a notice." The posting time is 14:55.

Li Shoufeng knew that this news was not sent by "Tiancheng Network", but naturally it was caused by those "hackers".

This is like telling the target in advance what time and where he will take action before a killer acts. Naturally, this will not be a kind reminder, it is clearly a contempt and despise of the opponent.

Li Shoufeng had never suffered such provocation. He was so angry, "Has the post been deleted?"

Li Shoufeng looked up and scared the customer service. The female customer service nodded repeatedly, "I have hidden all the posts. No one can see them except our customer service department staff..."

Li Shoufeng nodded, and after looking at the watch, it was still four minutes before fifteen o'clock. "Prepare for any accidents, please tell the Cybersecurity Department quickly and let them be prepared for defense. It is better to trust it than to trust it without..."

The customer service mm nodded and ran out in a hurry. When Li Shoufeng rushed to the security department, more than a dozen employees were on guard and were nervously sitting in front of the computer working, checking abnormal data, checking suspicious network connections, responsible for the security of the server itself, and deploying flood attacks for the firewall. Everyone had cautious and solemn expressions, fearing that the company's interests would be damaged due to their dereliction of duty. They could not afford the responsibility.

Li Shoufeng is still very confident about the security of the server, but this matter has attracted the attention of the company's senior management. He can no longer tolerate any major mistakes, and he can't help but be careless.

When I looked at the watch, it was already fourteen:59, and there was less than a minute left. "How are you preparing? Are you sure?" Li Shoufeng asked the manager of the Cyber ​​Security Department.

"Mr. Li, our company's servers and firewalls are still very secure, and it is unlikely to start from vulnerabilities. So, I think they are very likely to use flood attacks. We have done the corresponding defense work, and the servers that share the pressure have been turned on. When our servers are running normally, they can defend at least 60,000 home computers while attacking at the same time. For this attack, I am 90% sure that I can defend..." said Xin Shi, the security manager, said.

In fact, the security manager's network level is still good. Although he is not a top expert in China, he is also considered first-class. Since he took office, there has been no major problems with the company's servers. Li Shoufeng was relieved when he heard his words.

As time passed by minute by minute, it had reached the fifteen o'clock mentioned in the post, but the so-called attack was slow to move, and there was not even a single abnormal network data flow, which made the people present feel a little depressed.

After a while, the security manager couldn't help asking, "Mr. Li, will we be deceived? Isn't this a prank by a netizen?"

Mr. Li was also a little depressed while being angry. Is he too stressed over the past two days and some of his plants and plants have been in trouble? Although the hacker has been so ill, his company is not a vegetarian. If the technology is not up to standard, I am afraid that the company has been hacked hundreds of times long ago?

When the people present saw Mr. Li's expression, they all relaxed a little, but at this moment, an employee suddenly shouted, "No, our servers have all been restarted..." The people present's nerves that had just relaxed suddenly collapsed.

"What?" Li Shoufeng shouted in surprise, and then went to the computer to see that the entire anti-terrorism game, the total number of servers in five regions, was a total of dozens of units, all of which were being restarted. The number of people online was a row of dazzling red numbers - zero.

Everyone was stunned for a moment. They were ready to fight, but no one thought it would be like this. They didn't know what happened, and the server was silently hacked.

Just like the two armies are facing each other, and they are already in a battle, but the commander is assassinated. Although they are not injured, they have already lost.

"Didn't you say that there is no problem with our server security? Why is this happening?" Li Shoufeng roared at the security manager, and the latter was also shocked. He was scolded and came back to his senses.

"Our server is indeed fine..." The security manager looked helpless and depressed, "Mr. Li, although he is reluctant to admit it, there are only two possible situations..."

"One, the other party has an attack method that we don't know. Two, our server... has indeed a vulnerability, and this vulnerability has not yet broken out, so we have no relevant information at all..."

Although Mr. Li is not engaged in network security, he is in this position and knows more or less about this knowledge. If the other party has a loophole in his hands and his own people don’t know it, it would be like a blindfolded fight with others, and he would just catch him blindly and he wouldn’t know how he was.

"What should I do now?" Li Shoufeng sighed and asked helplessly.

The office was quiet, and everyone looked at the security manager. He thought for a moment, "I can only find someone. My friend is a "saber" and a member, and he is also a network security engineer who can rank among the top 20 in the country. He may have a way. I'll call him over now..."

"I have to do this..." Mr. Li nodded and reminded, "Your friend comes and asks him to thoroughly check our server. Will these people give up before they get a result? Be prepared to defend against the next attack..."

"I understand!" The security manager responded, turned his head to his subordinates and said, "Everyone who should work should go to work. We are elites in the domestic cybersecurity industry. We will get up wherever we fall. If you lose this time, you must find the venue next time. Go quickly..."

After hearing his words, everyone returned to their posts and worked more seriously and cautiously than before. The atmosphere in the entire office was very solemn.

...

In a residential house in a community in Binnan City, it forms a sharp contrast with the solemn atmosphere in the office there.

"Oh, too!! Happy cooperation!!"

The sound of Bingguang came out of the speaker, obviously in good mood, "What else do you think about how powerful their servers and firewalls are? It turns out that they are just that, they are simply vulnerable..."

Sasha smiled and said, "Do you think you are very serious? It's not because of Brother Fei's credit. If it weren't for the loophole information he provided, would you try to hack them? You'll get tired of your snot bubbles..."

Bingguang couldn't say that Sasha was so smirked and stopped talking. Mu Fei looked at the following table and said, "Now at three o'clock, take a break. It's time to have a meal. Let's get together at half past four o'clock. Let's give them some more..."

...

"Tiancheng Network" invited an expert from "Saberata". The man brought his equipment here and checked the server for more than half an hour. Finally, he frowned, "There is no problem with the server and the firewall. It seems that it is really similar to your speculation. It is very likely that the other party has mastered new attack methods or vulnerabilities, which is very troublesome..." He said to the manager of the network security department.

"Then, what do you do if you look at this situation?" asked the security manager.

"There is no way now. I will ask the people at the headquarters later to see if they can find some useful information..." After saying that, the expert shook his head, and then said in confusion, "The news about our saber is almost the most well-versed in the domestic cybersecurity industry. I haven't heard of any new loopholes recently. Where did this come from? Could it be that it is from abroad? Forget it, let's set up a normal defense first, and when they attack again, see if they can find any clues..."

After about two hours of the last attack, at 16:55, a message appeared again on the forum. The message was similar to the last one. It reminded that at 17:00, the entire server will restart again.

This time no one took this as a prank anymore, and stared at the data on their computers with wide eyes. However, the expert's defense and technology were obviously not strong enough. After one or two minutes at 17 o'clock, the entire server restarted again, and all players were disconnected collectively.

In the next few hours, the other party attacked the server every once in a while. At first, it attacked every two hours, but later it became an hour, half an hour, with the interval getting shorter and faster and higher frequency. It was very reasonable and would be in a low position.

From 3:00 pm to around 9:30 pm, the entire server has been disconnected for seven times, and players cannot play normally. Many posts on the official forum are full of complaints, cursing and venting the dissatisfaction of "Tiancheng Network".

Li Shoufeng had been in the office of the Cyber ​​Security Department for an afternoon. His phone rang lightly, showing the name of his superior leader. After thinking about it, he pressed the mute button and put it in his pocket. This was the second time the leader called him. He understood why, but before there was no result, he didn't know how to explain it to the superior and dared not answer it. It can be seen from the sweat beads on his head that he was under a lot of pressure.

"How are you doing? Is there any way?" Li Shoufeng wiped his sweat and asked several "experts" in front of him.

These people were invited by him and the network manager. It can be said that they had invited all the people they could think of. There were experts from private hacking organizations, experts in network security, senior maintenance personnel from server providers and network access providers, and even cyber police officers who were in charge of cyber crimes. However, they were helpless about this situation. After several hours of tossing, the final conclusion was that the server and firewall did have loopholes, and the other party had completely mastered the principle of the loophole, but the party knew nothing about it. In other words, now he was beaten with his eyes closed and was slaughtered.

After a while of silence, the Internet policeman said seriously, "It's over, I have a way, maybe I might as well give it a try..."
