After asking this question, Han Yingqiu glanced at the paper under Jin Yuxing's hand and frowned immediately. As a student in the Department of Computer Science, Han Yingqiu certainly knew that mathematics and computer theory have many similarities.
However, early exposure to too advanced theories will only make beginners confused and is not conducive to systematic learning.
So she added: "This seems to be Professor Su's paper from the Department of Mathematics. Will it be difficult for you, junior, to read it?"
At this time, Jin Yuxing turned around and said calmly: "It's a bit difficult to understand. I'm just thinking about it!" [bsp; Then, he stood up, picked up the stack of papers, patted them, and continued to sigh.
: "Professor Su's mathematical theory is profound and inscrutable. I think I'd better come back to study it in two years!"
After saying that, Yuxing walked to the borrowing desk and whispered two words to Xie Rui: "Return the book!"
Han Yingqiu was stunned by Yuxing's series of words and actions, but she intuitively felt that maybe Yuxing had found what he wanted in the paper. She really wanted to step forward and grab the stack of paper exams.
I am a star in school, but if I really want to do that, it would be too unreserved.
Just as he was thinking about it, Xie Rui suddenly called out: "Sister, please come over and take a look. It seems that there is something wrong with the computer!"
"What's going on?" Han Yingqiu hurriedly came over to take a look, and sure enough, the computer that handles borrowing records had a jamming problem.
"Restart it!" Yuxing suggested climbing on the counter.
When Xie Rui heard this, she turned to look at Han Yingqiu.
"Do as he says!" Han Yingqiu also agreed.
But after restarting, it still freezes.
Yu Xing and Han Yingqiu both frowned, looked at each other, and said in unison: "I'm afraid I'm poisoned!"
"Then senior sister, come and take a look!" Xie Rui quickly gave way.
Han Yingqiu did her job and immediately sat down in front of the computer and started typing on the keyboard. She checked the background first.
The process manager slowly popped up more than ten seconds after Han Yingqiu pressed the shortcut key. Yuxing glanced at it and found no unnecessary abnormal processes in it.
You know, the computers that store borrowing records are directly connected to Tupiao Astronomy. But now that the machine is not infected, but it is so stuck, there is only one possibility.
"The campus network of Peking University may have been attacked by hackers!" When Han Yingqiu had just judged the reason, Yuxing had already announced it.
Han Yingqiu glanced at Yuxing in surprise and continued to type on the keyboard, trying to access the campus network homepage.
Unfortunately, the browser returned a message saying: "The service is busy and cannot be accessed!"
"Ping under dos and see if you can connect to the external network!" Yuxing made another suggestion.
Glancing at Yu Xing angrily, Han Yingqiu immediately complied.
In fact, anyone who claims to be a computer expert hates other people dictating from the side. However, Yuxing's suggestions are always taking the lead, so Han Yingqiu has nowhere to vent his anger.
I pinged the IP addresses of several large portals, but none of them could connect.
Xie Rui next to her also saw the problem at this time. It was definitely a hacker attack. She asked: "What should we do now?"
Right now, students are coming to return books one after another at the borrowing desk. If we don't handle this matter in time, I'm afraid there will be trouble later!
Han Yingqiu glanced at the various boys in front of the stage who looked at her face more than at the liveliness, frowned slightly and said, "Brother Jin, do you have any advice?"
Although Han Yingqiu is a talented girl in the computer department, hacking technology is not her strong point and she is only superficial. Faced with such cyber attacks, she also feels helpless.
Yuxing thought for a while and asked, "Is there a computer with better configuration?" In fact, he wanted to ask if there was a separate room for him to operate.
"Yes! It's in the office inside!" Han Yingqiu said, "I'll take you there, Rui'er, you take care of it first and make a note of everyone who has returned the books!"
Before the bitter-faced Xie Rui could complain, Han Yingqiu brought Yuxing into the office.
After Han Yingqiu entered the system login password, Yu Xing said: "Senior, please go out too!"
"You said I...will go out too?" Han Yingqiu asked stammering in extreme embarrassment.
"Yes, I need to be alone for a while!" Yuxing said without any doubt.
Han Yingqiu had no choice but to glare at Yu Xing fiercely, slam the door and go out.
You are all here, otherwise I would open the door and come in by myself, without even using the login password! Yuxing secretly locked the door of the office, and then released his mental power instantly, intruding into Tupiao Astronomy through the computer.
…
"Eh!? Senior sister, why did you come out again?" Xie Rui said in surprise.
Han Yingqiu said harshly: "I'm afraid you're busy, so I'll come out to help you! Jin Yuxing is enough inside!"
Xie Rui sweated in her heart. She could hear that when Han Yingqiu said the word "Jin Yuxing", he said it through his back teeth.
At this time, the buzzing of students could be heard faintly from downstairs and the nearby reading room. Apparently everyone had discovered the problem of network lag and was making a fuss about it!
In the office, a layer of white sweat had appeared on Yuxing's forehead.
There is no way, the amount of calculation is too much.
It's really big!
Yuxing's mental power only extended to the first node gateway connecting the Beijing University campus network to the external network, and he was shocked by the astonishing data flow. How could this be a hacker invasion? How dare a whole hacker group attack the Beijing University campus.
The Internet sends spam information with the intention of blocking the entire network channel.
But after thinking about it, Yuxing felt that something was wrong with this. After all, the campus network of Peking University can close the connection to the external network, but why would this happen? Could it be that there is a traitor, or something else?
situation?
Besides, if the channel is blocked, even if the invading party wants to obtain any information, it will be difficult? The other party can't be so hopelessly stupid, right?
This series of questions lingered in Yuxing's mind, making his thoughts somewhat disordered.
Since the other party dares to do this, he must be prepared for retaliation. Let me show you how powerful he is! Yuxing thought of this and no longer bothered to care about these DDoS attacks. He just concentrated his energy in one place and started.
Follow the clues and follow the clues.
The intruder used multiple IP addresses to send junk data to Beijing University at the same time. Multiple springboards were set up for each IP address. Many of these springboards were servers of some large multinational groups. Therefore, if ordinary hackers were to conduct counter-tracking, they would probably break through.
These servers with super firewalls are difficult. However, this is not a problem for Yuxing at all. In the face of Yuxing's strange "telecommunications mental power", any security strategy on the wired network is vulnerable.
Soon, Yuxing found one of the IP addresses where the attack was launched, which came from an IT company near San Francisco, USA.
What I didn’t say, get rid of it!
Yuxing just sent a small command to the company on the other side of the ocean through the Internet in the form of brain waves. Within a few tenths of a second, large areas of bad sectors appeared on the hard drives of all the computers in the company.
These computer hard drives are like white paper covered with pencil drawings, and Yuxing's mental power is like countless erasers, erasing these pencil drawings into a mess in just a moment.
However, this was only the beginning of Yuxing's revenge. At the same time, the Internet Software Alliance in California also suffered a similar attack. Within two or three seconds, the hard disk array of the auxiliary root server on the IP address 192.5.5.241 was destroyed.
There was smoke all over the place, and then the line went offline.
There was a panic in the ICANN building, and the phone calls were ringing one after another. CEO Rod was sitting in his office listening to the report of his subordinates, his eyebrows twisted together inadvertently. Could it be that the matter was exposed? The other party called the door so quickly
Really? Impossible! It’s absolutely impossible with Eastern Internet technology!
Soon, CIA also received the news and began to investigate the ins and outs of this serious hacking incident.
At the same time, some parts of the Internet in China also temporarily interrupted communications. However, the campus intranet of Peking University suddenly became smooth.
"Sister, it seems that the intranet is normal again!" Xie Rui has been paying attention to the computer, and she soon found that the computer was not as stuck as before.
When Han Yingqiu heard this, he was stunned. Then he looked at his watch and thought to himself: It's only been three minutes! Darling, he can't be so awesome!
"Then you quickly handle all the borrowed books from these students, and I'll go in and take a look!" Han Yingqiu said.
In fact, if Han Yingqiu, the school belle, hadn't been waiting at the library desk for the past four or five minutes, the boys around would have started to make a fuss. Fortunately, everyone was just looking at Han Yingqiu, the beauty, and wished that the network card would be used again.
A little longer!
As soon as he pushed the door open, Han Yingqiu found that Yuxing had locked the door from the inside. He stamped his feet angrily and went back to sit down next to Xie Rui, where he felt sulky.
Xie Rui, while skillfully handling the borrowing and returning of books from each classmate, asked: "Senior, what's wrong?"
"Nothing!" Han Yingqiu didn't want to answer the question directly. He casually took the book that a boy returned and said firmly: "Where is your library card?"
The boy was still proud that he was personally received by Han Yingqiu's campus belle, but when he heard Han Yingqiu's frosty tone, he immediately shrank and handed over his library card tremblingly, not daring to go any further.
At this time, Yu Xing walked out of the office tiredly and said feebly: "Who...remember that I returned Professor Su's paper! I'm leaving first!" After saying this, he didn't even blink.
He glanced at Han Yingqiu and left without any explanation.
Han Yingqiu wanted to chase the general and beat Yuxing violently, but when he thought about his ability to kick off his sixth-degree black belt, he lost the courage again. As a result, the boys and girls who came to return the books all felt that
The campus beauty of Han University is in full swing.
As soon as I returned to the dormitory, I heard Zhang Yi boasting about Chinese hackers fighting against American hackers.
Seeing Yu Xing come back, he immediately greeted him: "Lao San, do you know about the hacker war just now?"
Yuxing looked stunned and said: "Where is it?"
"Ha - Third brother, you don't even know this. You are so out. Just listen to what I'm telling you..."
(It’s late~Sorry~~There are too many relatives visiting these days~~~)
