The sudden sound of the sirens startled everyone.

At this time, most of the students visited the third floor, and when they heard the voice, everyone looked at Qingli with a puzzled expression.

They didn't know what the alert meant.

At this moment, Qing Li's face was very ugly.

Others didn't understand what the alarm just now meant, but he knew that it was a warning from the system that caught the traces of hackers.

He just told Chen Yang that the defense system was impossible to break, and now there were hackers who had hacked into the internal system of the institute, which was completely slapping himself in the face.

"Qin Linlin, what's going on?"

Qing Li shouted to the other side of the corridor with a gloomy face.

A girl dressed in sportswear and wearing a ponytail ran over, with a nervous expression on her face, ran to Qing Li's side, and said in a low voice: "Doctor, the system has been hacked, and it has entered the internal procedures of the institute. ”

Qin Linlin is the commissioner in charge of system security observation, although she was also explaining to the students of Dong'an University of Technology just now, she still pays attention to the dynamic information of the institute's system security reflected on the mobile app.

So when there's a hack, she knows right away.

The others were far away and did not hear Qin Linlin's report to Qing Li, but the five students who Qing Li was responsible for explaining, Chen Yang, Lin Rou and the other three, heard it clearly.

Chen Yang shook his head, there is no absolute security in this world, whether it is a computer system or reality, there is none.

Qingli's confidence in Microsoft's defense system is a little too blind, so now the hacker's intrusion has made Qingli a little unexpected.

But this is someone else's business, and Chen Yang doesn't want to interfere.

He stood beside him, without saying a word, to see how Qing Li was going to solve it.

Confirming that it was a hacker intrusion, Qing Li frowned, and said to Qin Linlin in a deep voice: "At present, the hacker has entered the first layer of defense, have you caught the hacker?"

Qin Linlin showed an ugly expression on her face and said: "The hacker's technology is very smart, and now the system only judges that there is a hacker, but there is no trace of the location of the hacker and the program it has gone through. ”

This means that you know that the thief has entered your house, but you can't see it, you can't touch it, you don't know where the thief is.

It's easier said than done to catch a thief.

"Bring in the people in charge of system security, find the traces of the hackers first, and then use the attack code to smash the hackers. He provoked us, and he must not be spared. ”

Qing Li gave an order to Qin Linlin, and Qin Linlin immediately went to comply.

He also walked towards the elevator, intending to go to the main control room on the fourth floor, where he could see the system monitoring status of the entire research institute.

He had to be cautious about this matter.

Microsoft's defense system is very powerful, and after the opponent breaks through the defense, he moves freely in the internal system of the institute without a trace, which shows that the opponent is a master.

Moreover, the information of this institute is very important, and whether it is destroyed by hackers or stolen by a certain part, the loss will be very serious.

Not only economic losses, but also technical losses.

Seeing Qing Li walking towards the elevator, Ren Keming walked over with a puzzled look on his face, and asked in a low voice, "Qing Li, what happened?"

Qing Li said: "Teacher Ren, the system of the institute has been hacked, and I must now preside over the overall situation and defeat the hackers." ”

"So serious!"

Ren Keming showed surprise on his face and followed Qingli: "Let's go, I'll be with you." ”

Qing Li thought about it, anyway, if he fought against hackers, he would not leak the secrets of the research institute, and it would also be beneficial to let Ren Keming go over to help.

After all, Ren Keming is the deputy dean of the School of Computer Science, and even if he is not good at fighting hackers, he can still make some suggestions.

Immediately, the two got on the elevator and went straight to the main control room on the fourth floor.

For a while, the people in charge of the overall situation were gone, some of the researchers in charge of the commentary were also busy defending against hackers, and the students had no one to organize and began to discuss it.

"What's the matter, why did Teacher Ren and Senior Qing Li go upstairs?"

"What's the alarm just now?"

"Is it a drill?"

"Drill fart, just now Senior Qing Li was in charge of explaining to us, and I heard one of his female subordinates report to him, saying that there was a hacker who hacked into the internal system of the institute. ”

When they heard this, the students were very surprised and immediately became excited.

"I really didn't expect to see a hacker war today. ”

"Able to attack the system that enters Microsoft Research, this hacker seems to be a master. ”

"I don't know how Senior Qing Li will deal with this hacker, whether to smash the hacker code, or trap the other party in the system, or follow the hacker code to trace the past and attack the other party's host. ”

The students were talking and expressing their opinions, and as computer science students, they were all eager to try.

I don't know who instigated it, everyone went up to the fourth floor, wanting to see how Qing Li and the others dealt with the hacker invasion.

There were fewer and fewer people on the third floor, Lin Rou looked at Chen Yang and asked, "What are we doing now?"

Chen Yang looked back at the end of the corridor, thinking of the so-called "black hole" project, he always felt that things were not so simple.

He said to Lin Rou: "Let's go, let's go up and have a look." ”

The two went up to the fourth floor, only to see that the students were gathered at the door of the main control room, expecting Qing Li to come out and pass on the news and tell everyone that he had repelled the hackers.

Because the institute is usually staffed by insiders, and there are no research projects in the main control room, which is mainly used to observe the security of internal systems and the distribution of internal information, etc., the main control room is surrounded by glass walls, and everyone can see everything inside.

I saw that the main control room was full of computers, and each monitor was displaying a string of codes at the moment, and the code was changing rapidly, and before I could see it clearly, it had already become other codes.

More than a dozen staff members, constantly operating in front of different computers, the atmosphere is solemn, the expression is tense, and it seems that the situation is very tricky.

Qing Li sat at a large table, and there were five monitors in front of him, displaying different information.

He put his hands on the keyboard, constantly typing, and from time to time moving to other keyboards, looking very chic, but his face became more and more ugly.

Ren Keming stood behind him, his expression becoming more and more solemn.

Unconsciously, half an hour passed, and it didn't seem to be going well in the main control room.

The students who were originally excited outside the main control room quieted down.

Everyone realized that the institute seemed to be in trouble, and the hackers who invaded were very strong, and Qing Li had no way to deal with it for a while.

Bang.

Suddenly, Qing Li slammed the keyboard, startling everyone.

He grabbed his hair and yelled, "Where the hell is this bastard hiding?"

After half an hour of hard work, the entire team, including Qingli, found nothing except the code that hackers broke the firewall.

In other words, the hackers were hiding in the internal systems of the institute and became invisible.
