Chapter 211: lesson

　　Chapter 21 Chapter 　Lesson (1st on 2nd)
　　 The female employee of the customer service department in the OL outfit handed the information in his hand to Li Shoufeng's desk, and then took two steps back. His face was slightly uneasy, and he seemed to be afraid that he would be angry with himself.
　　 While Li Shoufeng glanced at the content on the paper, he immediately raised his eyebrows, patted the table with his palms, and gritted his teeth innocently, "arrogant, too arrogant!!"
It turned out that the paper was printed with a message from the official counter-terrorism forum. The title is "Notice of Disconnection", the content is very simple, only one line, "The counter-terrorism online service in the whole region will be renewed at 15 o'clock. Activation, all online players will be offline, hereby notified.", posting time is 14:55.
　　Li Shoufeng knew that this message was not sent by the "Tiancheng Network", and naturally came from the hands of those "hackers".
　　It's like telling the target beforehand when and where the action will take place before a killer action. This will naturally not be a reminder of good intentions, which is clearly to despise and look down on the opponent.
　　 Where did Li Shoufeng suffer from this kind of provocation, he was so angry, "Did the post be deleted?"
　　Li Shoufeng looked up and frightened the customer service MM. The female customer service nodded again and again, "I have hidden the posts, except for our customer service staff, no one else can see..."
Li Shoufeng nodded and looked at his watch for four minutes to 15 o'clock. "Be prepared for the rainy day. Please quickly tell the network security department to let them prepare for defense. They would rather have it than have nothing... "
The customer service MM nodded and rushed out. When Li Shoufeng rushed to the security department, more than a dozen employees were waiting in line, sitting nervously working in front of the computer, viewing abnormal data, viewing suspicious network connections, responsible for the server itself Safe, for the firewall to defend against flood attacks, everyone is cautious and dignified on their faces, fearing that the company's interests will be damaged because of their negligence, they can not afford the responsibility.
　　Li Shoufeng is still very confident in the security of the server, but this matter has already attracted the attention of the company's senior management. He can no longer tolerate any major mistakes, and he can't help but be cautious.
　　Looking at the watch, it is already 14:59, less than a minute, "How is it going? Are you sure?" Li Shoufeng asked the network security department manager.
"Mr. Li, our company's servers and firewalls are still very safe. It is unlikely that we want to start with vulnerabilities. So, I think they will use flood attacks in 10 or 9 times, and we have done corresponding defenses. The servers that work and share the pressure have also been turned on. When these servers are running normally, we can defend at least 60,000 home computers at the same time. For this attack, I have 90% assurance that I can defend..." The manager of the security department believes that Said dutifully.
In fact, the network level of the security department manager is good. Although he is not a top expert in China, he is also a first-class. Since he took office, there have been no major problems with the company's servers. When he heard him, Li Shoufeng was considered to be loose. Took a breath.
With the passage of time, one minute and one second passed, it was already 15 o'clock, but the so-called attack was slow and unmoved, and there was no abnormal network data flow, which made people present depressed. .
　　 After a while, the security manager couldn’t help but ask,
Mr. Li, will we be scammed? Isn’t this a netizen’s prank?

　　In addition to being relieved, President Li is also a little depressed. Is it because he has been under too much pressure in the past two days, and some plants are all soldiers? Although the hacker suffered, but his company is not vegetarian, if the technology is not enough, I am afraid this company has been hacked hundreds of times, right?
When the present people looked at Mr. Li's expression, they all relaxed a little, but at this moment, an employee suddenly shouted, "No, our servers are all restarted..." The nerves of the people who had just relaxed suddenly collapsed again. tight.
"What?" Li Shoufeng shouted in surprise, and then looked at the computer. The entire counter-terrorism game, the master and sub-servers of the five regions, a total of dozens of units, all of which are already restarting, the number of online people is a row of dazzling Red number-zero.
　　 For a time, everyone was dumbfounded. They had made enough preparations to fight a battle, but no one thought that the result would be like this. I don't know what happened, and the server was hacked silently.
　　 is like the two armies fighting against each other, they are already ready to fight, but the coach was assassinated. Although he did not hurt a soldier and a horse, he has lost.
　　 "Don't you say that our server is safe? How could it be like this?" Li Shoufeng shouted at the manager of the security department, and the latter was also in amazement. After he scolded him, he came back.
　　 "Our server is really no problem..." The manager of the security department looked helpless and depressed. "Although Li is very reluctant to admit it, there are only two possibilities for this situation..."
　　 "One, the other party has an attack method that we don't know about, and two, our server... does have a vulnerability, and this vulnerability has not yet broke out, we have no relevant information at all..."
Although Mr. Li is not engaged in network security, he is in this position. He knows more or less of this knowledge. If the other party has a loophole in his hand, and he does not know it, it is tantamount to Blindfolded to fight with other people, it is basically blind blindness with two eyes, do not know how to suffer.
　　 "What now?" Li Shoufeng sighed and asked helplessly.
The office was quiet, and he looked at the security manager. He thought for a moment, "I can only find someone. My friend is a "saber". He is a member of the top 20 network security engineers in China. He may have Way, I will call him over now..."
"I had no choice but to..." Mr. Li nodded and urged, "Your friend will let him thoroughly check our server. If these people don't get a result, will they give up and defend themselves next time? Ready to attack..."
"Understood!" The manager of the security department responded and turned his head to his employees. "All those who work should go to work, but we are the elites in the domestic cybersecurity industry. We must climb up whenever we fall. This time we lose, next time. Be sure to get the scene back and go quickly..."
　　 listened to his words, everyone returned to their posts, working more carefully and cautiously than before, and the atmosphere of the whole office was very dignified.
　　……
　　In a residential area of ​​a residential area in Binnan City, there is a sharp contrast with the dignified atmosphere in the public office over there.
　　 "Oh!! Happy cooperation!!!"
　　 Bingguang's voice came out from the speaker, obviously clearly interested, "What are their servers and firewalls to say how powerful they are, but it's just like that, it's simply not vulnerable..."
　　Gauze smiled and said, "Do you think you are a victim? It's not because of Brother Fei's credit, or if he had the vulnerability information provided by him, would you try to black them again? Tired of your nose and bubbles..."
Bingguang said nothing but gauze, smirked and said nothing, Mu Fei looked at the table below and said, "Now three o'clock, take a break, it's time to eat and eat, gather at four thirty, let's give them a second... "
　　……
"Tiancheng Network" invited an expert from "Sabre". The man brought his equipment here and checked the server for more than half an hour. Finally, he couldn't help frowning. "There is no problem with the server and the firewall. Look. It's almost the same as your guess. It is likely that the other party has mastered new attack methods or vulnerabilities, which is very troublesome..." he said to the network security department manager.
　　 "So, what do you think about this situation?" the manager of the security department asked.
"There is no way right now. I will ask the people at the headquarters for a while to see if I can find some useful information..." The expert shook his head and then puzzled, "The news of our saber is almost in the domestic cybersecurity community. It’s the most well-informed. I haven’t heard of any new loopholes recently. Where did this character come from? Is it impossible to succeed abroad? Forget it, let’s arm it normally. When they attack again later, See if you can find any clues..."
　　About two hours after the last attack, at 16.55, a message appeared again on the forum. The message was similar to the last one, reminding that at 17 o'clock, the entire server would restart again.
This time no one took this remark as a prank. They all stared at the data on their computers, but the expert’s defense and technology were obviously not strong enough. The whole server restarted again at 17:00 and 1 or 2 minutes. All players are offline.
In the next few hours, the other party attacked the server every once in a while. At the beginning, it attacked once every two hours, but later it became an hour, half an hour, the interval became shorter and shorter, and the frequency increased. The higher the coming, the more reasonable it is to be unforgiving, and the situation will be low.
From 3 pm to around 9:30 pm~EbookFREE.me~ The entire server has been dropped for seven times, and players are unable to play the game normally. Many posts on the official forum are complaints, evil... curses, and they all vent. "Tiancheng Network" dissatisfaction.
Li Shoufeng has been in the office of the Cyber ​​Security Department for an afternoon. His phone rang lightly, 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 already the second leader. I called him again, but I couldn’t understand why, but before there was a result, he didn’t know how to confess to it. He didn’t dare to take it. From the sweat beads on his head, his pressure was absolute. Not small.
　　 "Several, how is it, is there any way?" Li Shoufeng wiped his sweat and asked several "experts" in front of him.
These are the people he and the manager of the network department have invited. It can be said that all you can think of are invited. There are experts from private hacker organizations, experts in network security, and senior maintenance personnel from server providers and network access providers. There are even cyber policemen who specialize in cybercrime, but they are helpless about this situation. After a few hours of tossing, the final conclusion is that the server and firewall are indeed vulnerable, and the other party fully mastered the vulnerability. The principle, but Fang Fang knows nothing about it, that is to say, Fang Fang is in a situation of being beaten with his eyes closed, letting anyone slaughter.
　　 remained silent for a while, and finally the net policeman said solemnly, "The matter is here.
