After asking this question, Han Yingqiu glanced at the paper under Jin Yuxing's hands, and immediately frowned.As a student of the Department of Computer Science, Han Yingqiu certainly knows that mathematics and computer theory have many similarities, but early exposure to too advanced theories will only confuse beginners and is not conducive to systematic learning.

So she said again: "This seems to be the thesis of Professor Su from the Department of Mathematics. Is it difficult for you to read it?"

At this time, Jin Yuxing turned his head and said calmly: "It's a bit difficult to understand, I'm just thinking about it!"

Immediately, he stood up, picked up the stack of papers, patted them, and continued to sigh: "Professor Su's mathematical theory is so unpredictable, I think I should study it again in two years!"

After finishing speaking, Yu Xing walked to the borrowing desk and whispered two words to Xie Rui: "Return the book!"

Han Yingqiu was taken aback 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 go forward and snatch the stack of papers to test Yuxing, but if she really wanted to do that, she would be too immodest.

While thinking about it, Xie Rui suddenly called out: "Senior sister, please come over and take a look, it seems that there is something wrong with the computer!"

"What's going on?" Han Yingqiu hurried over to take a look, and sure enough, the computer processing the borrowing records was stuck.

"Restart!" Yu Xing climbed on the counter and suggested.

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 stuck.

Yu Xing and Han Yingqiu both frowned, glanced at each other, and said in unison: "I'm afraid they are poisoned!"

"That's still senior sister, come and see!" Xie Rui hurriedly stepped aside.

Han Yingqiu did her part, and immediately sat 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. Yu Xing glanced at it, but did not find any redundant abnormal processes in it.

You must know that the computers that store borrowing records are directly connected to the library's intranet, but the machines are not poisoned at the moment, but they are stuck like this, so there is only one possibility.

"The campus network of Beijing University may have been attacked by hackers!" Yu Xing had already announced it when Han Yingqiu had just figured out the reason.

Han Yingqiu glanced at Yuxing in surprise, then continued typing on the keyboard, trying to access the homepage of the campus network.

Unfortunately, the browser returned a message saying: "The service is busy and cannot be accessed!"

"Ping under DOS to see if you can connect to the external network!" Yuxing made another suggestion.

Taking a reproachful glance at Yu Xing, Han Yingqiu immediately complied.

In fact, anyone who claims to be a computer expert hates other people to dictate.But right now, Yuxing's proposal is ahead everywhere, making Han Yingqiu angry and unable to vent his anger.

I pinged the ip of several large portal websites, but none of them could be connected.

Xie Rui, who was on the side, also saw the problem at this time. It was hacked. She asked, "What should we do now?"

Right now, there are students coming to return books one after another at the borrowing desk. If this matter is not handled in time, I'm afraid there will be trouble later!

Han Yingqiu glanced at her face more than at the lively boys in front of the stage, frowned slightly, and said, "Brother Jin, do you have any advice?"

Although Han Yingqiu is a talented woman in the Department of Computer Science, she is not good at hacking, she is only superficial in hacking. Facing such cyber attacks, she also feels helpless.

Yu Xing thought for a while, and said, "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, take care of it first, and make a note of all those who return 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: "Sister, please go out too!"

"You said I... went out too?" Han Yingqiu stammered in embarrassment.

"Yes, I need to be alone for a while!" Yu Xing said without doubt.

Han Yingqiu had no choice but to give Yuxing a hard look, and slammed the door and went out.

"This is because you are all here, otherwise I will open the door and come in by myself, without even needing a login password!" Yu Xing thought to himself and locked the door of the office, then released his mental power in an instant, and hacked into the library's intranet through the computer.

……

"Eh!? Sister, why are you out again?" Xie Rui asked in surprise.

Han Yingqiu insisted: "I'm afraid you're busy, so I'll come out to help you! It's enough to have Jin Yuxing inside!"

Xie Rui felt 'sweat' in her heart, she could tell that when Han Yingqiu said the word 'Jin Yuxing', she gritted her back molars.

At this time, there were faint buzzing sounds from the students downstairs and in the nearby reading room. It was obvious that everyone had discovered the problem of the card network, and they were talking about it!

In the office, a layer of white sweat had formed on Yuxing's forehead.

No way, the amount of calculation is too large.

Really big!

Yuxing's spiritual power only extended to the gateway of the first node connecting the Peking University campus network to the external network, and he was shocked by the astonishing data flow.Where is this tm a hacker intrusion, dare a whole hacker group is sending spam to the Peking University campus network, with the intention of blocking the entire network channel.

But after thinking about it, Yu Xing felt that something was wrong.After all, the campus intranet of Peking University can close the connection to the external network, but why does this happen?Is there a traitor, or something else?

Besides, the channel is blocked, even if the invading party wants to obtain any information, it will be difficult?Wouldn't the other party be so stupid as to be hopelessly stupid?

This series of questions lingered in Yu Xing's mind, making his thoughts a little disordered.

"Since the other party dares to do this, they must be prepared to be retaliated, and let me show you a little bit!" Yu Xing thought of this, and he didn't bother to care about these ddos ​​attacks anymore. He just focused his energy on one place, The action of following the clues began.

The intruder divides multiple IPs to send junk data to Beijing University at the same time. Each IP has multiple springboards. There are many servers of some large multinational groups in these springboards. Therefore, if ordinary hackers conduct anti-tracking, they may break through These servers with super firewalls are hard.However, all this is not a problem for Yuxing at all. In the face of Yuxing's weird "telecomification spiritual power", any security strategy on the wired network is vulnerable.

Soon, Yuxing found one of the IPs where the attack was launched, which came from an IT company near San Francisco, USA.

Didn't say, kill it!

Yuxing just sent a small instruction to the company on the other side of the ocean through the Internet in the form of brainwaves. Within a few tenths of a second, a large number 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 Yu Xing's mental power is like countless erasers, which can erase 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 192.5.5.241 was There was green smoke all over, and then dropped the line.

There was a panic in the building, and the phone rang one after another.CEO Rhodes sat in his office and listened to his subordinate's report, and his eyebrows could not help but knit together, "Could it be that the incident was exposed? The other party called so soon? Impossible! With Eastern Internet technology Absolutely impossible!"

Soon, CIA also received the news and began to investigate the ins and outs of this serious hacking incident.

At the same time, parts of the Internet in China were temporarily cut off from communications.However, the campus intranet of Peking University became unobstructed in an instant.

"Senior sister, it seems that the intranet is back to normal!" Xie Rui has been paying attention to the computer, and she soon found that the computer is not as stuck as before.

When Han Yingqiu heard this, he was stunned, then looked at his watch, and thought to himself: "It's only been 3 minutes! My dear, he won't be so smart!"

"Then quickly deal with the borrowed books of these students, I'll go in and have a look!" Han Yingqiu said.

In fact, if Han Yingqiu, the school belle, hadn't been standing at the borrowing desk for the past four or five minutes, the boys around would have gotten into a commotion.Fortunately, the beauty is delicious, everyone is only focused on indecently insulting the beautiful woman, and they wish this network card can last longer!

As soon as he pushed the door, Han Yingqiu found that Yuxing had locked the door from the inside, stomped his feet angrily, and went back to sit beside Xie Rui, sulking.

Xie Rui skillfully handled the borrowing and returning of each classmate's books, and asked, "Senior sister, what's the matter?"

"It's nothing!" Han Yingqiu didn't want to answer this question directly, so she casually took a book returned by a boy, and said stiffly, "Where's your library card?"

The boy was still proud that he was personally received by Han University's belle, but when he heard Han Yingqiu's frosty tone, he immediately froze, and handed over his library card tremblingly, not daring to overstep in the slightest.

At this time, Yu Xing walked out of the office exhaustedly, and said weakly: "Who... remember that I returned Professor Su's paper! I'll go first!" After saying this, he didn't even turn his eyes Sweeping Han Yingqiu glanced at her, not to mention any explanation, and left in a calm manner.

Han Yingqiu really wanted to chase after him and beat Yu Xing violently, but when he thought of his ability to kick the sixth-degree black belt, he lost his courage again.As a result, the boys and girls who came to return the books all felt the exuberant anger of Colonel Han.

As soon as he returned to the dormitory, he heard Zhang Yi happily bragging about the Chinese hackers fighting the American hackers.

Seeing Yuxing coming back, he immediately greeted him: "Third brother, do you know about the hacker war just now?"

Yu Xing looked stunned and said, "Where is it?"

"Ha - third child, you don't even know this, you are so out, listen to me..."
