Chapter 211 Lesson (2nd 1st Update) The female employee of the customer service department in an OL suit. He handed the information in his hand to Li Shoufeng's desk, and then took two steps back, his face slightly uneasy, as if he was afraid that he would be angry with him.

And Li Shoufeng looked at the content on the paper, immediately raised his eyebrows, slapped the table with his palm, and gritted his teeth and said, "Arrogant, too arrogant!!"

It turned out that the paper was printed with a message from the official anti-terrorism forum, with the title "Disconnection Notice", the content was very simple, only one line of words, "Anti-terrorism online all servers in the whole region will be restarted at fifteen o'clock sharp, and all online players will be disconnected, hereby notified." The time of posting is 14:55.

Li Shoufeng knew that this news was not sent by the "Tiancheng Network", but naturally from the hands of those "hackers".

This is like telling the target in advance when and where he will do it before a killer acts, which is naturally not a kind reminder, it is clearly a contempt and contempt for the opponent.

Where did Li Shoufeng suffer this kind of provocation, and he was so angry in his heart, "Did you delete the post?"

As soon as Li Shoufeng raised his head, he startled the customer service MM, and the female customer service nodded again and again, "I hid all the posts, except for our customer service staff, no one else can see ......"

Li Shoufeng nodded, and when he looked at his watch, it was still fifteen o'clock in four minutes, "Take precautions, you quickly tell the news to the Ministry of Cybersecurity, so that they can prepare for defense, and it is better to believe it than to believe it ......"

When Li Shoufeng arrived at the security department, more than a dozen employees were waiting for him, nervously sitting in front of the computer to work, checking abnormal data, checking suspicious network connections, responsible for the security of the server itself, and arming the firewall for flood attacks, all of them were cautious and dignified, for fear that the company's interests would be damaged because of their own dereliction of duty, and they couldn't afford the responsibility.

Li Shoufeng is still very confident in the security of the server, but this matter has attracted the attention of the company's senior management, and he can't tolerate any more big mistakes, and he can't help but be cautious.

When I looked at my watch, it was already 14:59, and there was less than a minute left, "How are you preparing?" asked Li Shoufeng to the manager of the network security department.

"Mr. Li, the security of our company's servers and firewalls is still very high, and it is unlikely that we want to start from the aspect of vulnerabilities. So, I think they're going to attack with floods, and we've done the corresponding defense work, and the servers that share the pressure have been turned on, and when our servers are running normally, they can defend against at least 60,000 simultaneous attacks on home computers, and I'm 90% sure that they can defend against this attack......," said the security manager, Shinshi.

In fact, the network level of the manager of the security department is still good, although he is not a top master in China, but it is also a first-class, since he took office, the company's server has indeed not had any major problems, hearing his words, Li Shoufeng is relieved.

As the time passed minute by minute, it had reached fifteen o'clock as mentioned in the post, but the so-called attack had not moved for a long time, and there was not even a bit of abnormal network data flow, which couldn't help but make the people present a little depressed.

After a while, the manager of the security department couldn't help but ask, "Mr. Li, will we be deceived, this can't be a prank by some netizen, right?"

Mr. Li was relieved, but also a little depressed, is it that he has been under too much pressure in the past two days, and some plants and trees are all soldiers? Although the hacker has been harmed, but his company is not a vegetarian, if the skills are not good, I am afraid that this company has been hacked hundreds of times, right?

When the people present saw Mr. Li's expression, they were all relaxed, but at this moment, an employee suddenly shouted, "Oh no, our servers have all been restarted...... The nerves of the people present who had just relaxed collapsed again.

"What?" Li Shoufeng shouted in surprise, and then looked at the computer, the entire anti-terrorism game, the total and sub-servers of the five regions, a total of dozens, all of which were already restarting, and the number of people online was a row of dazzling red numbers - zero.

For a while, everyone was dumbfounded, and their own people were ready for a big battle, but no one thought that the result would be like this, and the server was hacked silently.

It's like the two armies facing each other, and they have already set up their positions to go to war, but the commander has been assassinated, although not a single soldier or horse has been injured, but he has already lost.

"Didn't you say that there is no problem with the security of our server? How can this be?" Li Shoufeng roared at the manager of the security department, and the latter was also stunned, and he scolded him before he came back to his senses.

"There is indeed no problem with our server...... "The manager of the security department looked helpless and depressed, "Mr. Li, although I don't want to admit it, there are only two possibilities for this situation......"

"One, the other party has an attack method that we don't know how to do, and two, our server...... There is indeed a loophole, and this loophole has not yet broken out, so we don't have relevant information at all......"

Although Mr. Li is not engaged in network security, he is in this position, and he knows a little bit about this knowledge, if the other party has a loophole in his hand, and his own people don't know the way, it is tantamount to fighting with others blindfolded.

"Then what now?" Li Shoufeng sighed and asked helplessly.

There was silence in the office, and they all looked at the manager of the security department, and he thought for a moment, "I can only find someone, my friend is a member of the "Sabre", and he is also a network security engineer who can rank in the top 20 in China, he may have a way, I will call him over now......"

"That's it......" Mr. Li nodded and admonished, "Your friend came to ask him to thoroughly check our server, before these people get a result, they will not give up and prepare to defend against the next attack......

"Understood!" the manager of the security department responded, turned his head and said to his subordinate employees, "Everyone who should work will work, we are the elite of the domestic network security industry, where we fall, we have to get up, this time we lost, next time we must get the field back, go to ...... quickly"

After listening to his words, everyone returned to their posts and worked more carefully than before, and the atmosphere in the whole office was very solemn.

……

In a residential house in a community in Binnan City, there is a stark contrast to the solemn atmosphere in the office there.

"Oh yes!!Happy cooperation!!"

Bingguang's voice came from the speakers, obviously in good spirits, "What else do you say about how powerful their servers and firewalls are, it turns out that it's just that, it's not vulnerable at all......"

Sasa smiled and accosted, "Do you think you are very troubled? It's not the credit of Brother Fei, if it weren't for the loopholes he provided, you would try to hack them again......?"

Bingguang couldn't say anything about yarn, and he didn't say anything with a smirk, Mu Fei looked at the table below and said, "It's three o'clock now, take a break, it's time to eat and eat in a while, gather at half past four, let's give them another ......"

……

"Tiancheng Network" invited an expert from the "Sabre", and the person brought his own equipment here, so he gave the server a check and detection, tossed for more than half an hour, and couldn't help frowning, "There is no problem with the server and the firewall, it seems to be similar to your speculation, it is very likely that the other party has mastered a new attack method or vulnerability, which is very troublesome......

"So, what do you think of this situation?" asked the security manager.

"There's no way now, I'll ask the people at the headquarters for a while to see if I can find some useful information...... the expert said, shook his head, and then puzzled, "The news of our saber can almost be said to be the most well-informed in the domestic network security community, and I haven't heard of any new vulnerabilities recently, where did this character come from? Forget it, let's arm normally first, and when they attack again, see if they can find any clues......

At 16:55, about two hours after the last attack, a message appeared on the forum again, similar to the last one, reminding that at 17 o'clock, the entire server would restart again.

This time, no one took this as a prank anymore, and they all stared at the data on their computers with wide eyes, but the expert's arming and technical skills were obviously not strong enough, and at seventeen o'clock a minute or two, the entire server restarted again, and all players were collectively disconnected.

In the next few hours, the other party attacked the server every once in a while, at first every two hours, but then it became an hour, half an hour, the interval became shorter and shorter, and the frequency became higher and higher.

From three o'clock in the afternoon to about half past nine in the evening, the entire server has been disconnected seven times, players can't play normally, and many posts on the official forum are full of complaints, evil... cursed, venting the dissatisfaction of the "Tiancheng Network".

Li Shoufeng has been in the office of the Ministry of Cyber Security for an afternoon, his phone is ringing softly, showing the name of the superior leader, after thinking for a while, he pressed the mute button and put it in his pocket, this is the second time the leader has called him, why he understands it anymore, but before there is a result, he doesn't know how to explain to Lu Dao, he doesn't dare to answer, it can be seen from the sweat beads on his head that his pressure is definitely not small.

"How's it going, is there anything you can do?" Li Shoufeng wiped his sweat and asked a few "experts" in front of him.

These people are all invited by him and the manager of the network department, and it can be said that they have invited everything they can think of, including experts in civil hacker organizations, experts in network security, senior maintenance personnel from server providers and network access providers, and even cyber police in charge of cybercrime, but they are helpless against this situation, and after several hours of tossing, the most concluding conclusion is- There is indeed a vulnerability in the server and firewall, and the other party fully understands the principle of this vulnerability, but the other party is ignorant of it, that is, it is now in a situation where the party is being beaten with its eyes closed, and it is allowed to be slaughtered.

After being silent for a while, the last Internet policeman said solemnly, "The matter has come to this point, I have a way, I might as well give it a try......"
