Full-level boss is not easy to chase

He even added a paragraph of text and pictures after the exam questions of the School of Information.

The teacher who managed the computer room had to report to Principal Zheng, who was in charge of network security at the school.

At this time, all the students of the School of Information had seen those pictures and texts after handing in the papers, and fell into crazy discussions.

When they found the campus forum along the screen, they found that the top post of the campus forum had also changed into the same picture and text. Coach Shanghan’s posts were all marked with big red crosses, indicating slander!
In this case, the professors of the School of Information agreed that there was a deliberate attack by hackers and suggested shutting down the network.

Close the network.

Close the campus network, close the campus forum!
This incident is subversive for Peking University's School of Information, because Peking University, as a national key laboratory for information security development and testing, has been attacked by hackers. Saying that is simply a great insult.

Everyone in the key laboratory of the information department stayed on campus to participate in the internal test to check all loopholes.

However, a classmate finally asked weakly in the WeChat group of the Information Department of Peking University: Why does the school only look for security loopholes in the computer room, instead of paying attention to those photos and text descriptions?
It was a word that awakened the dreamer.

What are those words, what are those pictures?
Isn't it a virus they thought hackers put?

The professors of the School of Information were looking to fill in the doubts that the loopholes in the system had already been filled. In desperation, they opened the pictures and texts with those suffixes.

Is this loophole too big?

Who the hell is this, has entered the Peking University network system, and investigated the ins and outs of the hot search posts on the forum.

Someone took advantage of privileges to enter Peking University's monitoring system, pulled out a drawing that Ran Xiachu had drawn on draft paper, edited it on the spot, and posted the most popular post on the campus forum of Peking University.

painting?
The professors of the School of Information, led by President Zheng himself, looked at the painting in amazement.

If they hadn't seen Ran Xiachu drawing on scratch paper in the surveillance, they would have thought it was a photo.

It's just that.

The text under the first picture is the IP address, the IP address that used privileges to enter Peking University's network monitoring system. As long as you find this address, you can find the corresponding person.

It turned out that the file with the suffix after the test paper was to reveal the truth about the hot search post to the school, and also kindly provided clues to intrude into the network.

It was simply...too unexpected.

This operation alone is enough to prove that the hacker who messed up Peking University's network security system is just and reasonable.

For some reason, seeing the explanatory text of the first picture configuration, Principal Zheng secretly breathed a sigh of relief.

There are many national key laboratory research subjects on the network of Peking University's small courtyard. Although it is encrypted, if it is invaded and stolen by someone with ulterior motives, it will really suffer heavy losses.

Thankfully this hack is not a vandal.

The next picture is clearer and clearer. The students who turned on the computer in advance to take the exam all popped up shocking hot search posts on their computers, crusading against a certain advertising spokesperson for stepping on two boats, and appended Professor Han and Ran Xiachu a recording of .

This is the cause.

Next came a series of pictures, and someone entered the monitoring system again. This time, the IP address was the same as last time. It took only 10 minutes to take it out of context, intercept a part of the recording, and modify it into a hot search post. The means are added to the computers used by the students of the Faculty of Information for their exams.

A series of pictures express very clearly, the source of the hot search post of the picture, the time when it was added to the test paper, and the clear IP address.

The last picture is fixed in a certain area of ​​Peking University, and a big IP address is also written.

The meaning is very clear, all this is done by the person with this IP address!

Ten minutes later, when President Zheng led the professors from the School of Information to open the door of a dormitory in the Department of Medicine, and saw two girls sitting at the computer desk, he understood the cause and effect of all this.

Huo Yan and Liu Shan were invited to the principal's office to talk.

Next, is to find the hacker.

Yes, that hacker has enough sense of justice for Peking University to find out the culprit who spread rumors and stirred up public opinion, but!
The behavior of this hacker violated the laws and regulations of the national network security.

What is strange is that the professors of the School of Information came forward, but they could not find the trace of the hacker.

The problem is, those pictures and text suffixes suddenly became hours when they were six hours old.

It's like that hacker was born out of nowhere and then disappeared strangely.

How to do?
Network security cannot be ignored. This kind of offensive and extremely insulting behavior must be severely punished!

We can only find the person in charge.

This tossing also took a full two hours, so someone just jumped off the flight to the capital, and received a solicitation order from President Zheng of Peking University.

"Young Master Luo, there are hackers appearing in Peking University's network. After receiving the news, you must go to Peking University to deal with the hacker's time as soon as possible."

……

This is the first time that Peking University has shut down the network with such a big fanfare in such a long time. After the signal is blocked, the students' mobile phone signals can no longer enter the campus network of Peking University.

As a result, the discussion in the WeChat group exploded.

There are all kinds of guesses and information.

For example, this is a hacker testing a program he designed to challenge the security of Peking University's network.

For example, this is a joke of a student from the School of Information.

For example, a few girls did these things because of jealousy.

There are all kinds of rumors.

Of course, Xia Chu didn't pay attention to this, she set the suffix to be automatically cleared in two hours, it was just a moment of anger, to teach Huo Yan and Liu Shan a lesson.

……

The exam season is over, which means that the winter vacation is coming.

Huang Lei, who finished the professional course, was aroused by the sudden appearance of the suffix. When Xia Chu came back, she excitedly handed Xia Chu a bucket of instant noodles: "Brother Chu, I know that I will not go to the restaurant to eat for my own sake." , come, come, I will accompany you to eat bucket noodles."

Xia Chu took the bucket of noodles and soaked them in it: "Don't you want to eat Xiaojun's liver?"

"We have an appointment to eat fat beef hot pot tonight." Huang Lei also soaked the bucket noodles, and the two waited to eat.

Fat beef hot pot?

She also made an appointment with someone for Fat Niu Hot Pot, can't it be the same one?

Seeing Mo Yuyan's clear eyes at the beginning of Xia, Huang Lei felt a little embarrassed: "Well, I'll go home tomorrow, Brother Xu invites me to eat fat beef hot pot tonight, Brother Chu, why don't you come too ?”

Xia Chu shook his head: "I have something to do."

Two people were eating bucket noodles with forks, Xia Chu's cell phone rang, and there were only three words: "What did you do?"

"I did."

"Do you know how serious the consequences of ignoring Peking University's network security and the security of national key projects are?" someone's tone on WeChat was completely the attitude of the police teaching criminals.

cut!
It doesn't matter if someone else hacked into the campus surveillance network, and she was punished by Xingshi for just a little punishment?
Somehow, ever since that trending post was posted, the grievance and anger hidden in my heart were suddenly ignited, Xia Chu directly replied: "I will bear the serious consequences, it has nothing to do with you!"

Block it, block it, block it directly!
