With Instructor Zheng's ruling, the first game of the competition came to an end.

Yang Dedi sat down in his chair with a dejected face and silently stopped talking. However, he was still a little unconvinced in his heart after all. Reinvigorated, he looked up at Shen Yun, who was smiling at him in the distance, and said:

"Come again, I'll attack, you defend."

Shen Yun smiled and said those two words again: "Okay." ”

The students who were watching from a distance were also stunned at this moment. Many people here still haven't understood how Shen Yun hacked into Yang Dedi's computer.

But time was too late for them to think about it, because the second round of the contest had already begun.

Yang Dedi was still typing on the keyboard, but on the students' screens, Shen Yun's screen was motionless. Just wondering if there was a mistake in the transfer, when they raised their heads, the students found that Instructor Zheng had walked to their side.

"Instructor, is there a problem with the transfer? Why hasn't Shen Yun's screen moved? ”

Instructor Zheng shook his head and replied in a low voice, "The screen didn't move because Shen Yun didn't operate it at all. I don't believe you can see what he is doing with his hands now? ”

The students stretched their necks, and suddenly found that Shen Yun actually put his hands behind his head. Looking at this, he was simply waiting for Yang Dedi to come over and attack.

"This kid is too big, he doesn't look down on people so much."

One of the students complained to Instructor Zheng in a low voice with a little indignation. In his opinion, Shen Yun was contemptuous of Yang Dedi.

Instructor Zheng sighed and explained in a low voice: "If he moves at this time, he is really underestimating." Let's see how Yang Dedi gets it first. ”

I have to say that Yang Dedi dared to say the words he was proud of before, and he did have a few brushes. No, he and Shen Yun thought together. First fight for the management of the console, and then start infiltrating Shen Yun's computer.

And what made him happy was that Shen Yun was indeed not good at defense, no, now on his screen, the desktop of Shen Yun's computer had appeared. Yang Dedi also learned from Shen Yun's example, and controlled the background to make the words "You lost" on the screen.

In his opinion, this can be regarded as a tie, and his face is finally saved.

After doing all this, Yang Dedi began to look up at Instructor Zheng, hoping that Instructor Zheng would announce the results of the contest at this time.

However, he was disappointed. Instructor Zheng didn't say a word, just looked back and forth at Shen Yun and him with a somewhat strange look. This kind of gaze made Yang Dedi's heart suddenly, and then he set out to check the results of his invasion again.

But let him check it three or two times, and the result was that the three words on Shen Yun's computer had not been eliminated. In other words, in his opinion, Shen Yun has not fought for control of the computer so far.

"Report, instructor, isn't it time to announce the results?"

Yang Dedi counted the time to thirty and hurriedly began to urge.

However, something hit him even harder. Instructor Zheng looked at himself with a regretful expression, shook his head and said, "Yang Dedi, you lost. ”

"What? No way? Yang Dedi didn't believe Instructor Zheng's judgment at all, and exclaimed. Then he pointed to Shen Yun's screen and said, "Instructor Zheng, look at his screen, I have left traces on it, and he has not changed it at all." ”

Looking at Yang Dedi's appearance, Instructor Zheng sighed, and then said, "Yang Dedi, go and see for yourself if there is any trace of you on Shen Yun's computer screen." ”

Yang Dedi, who didn't believe in evil, hurried over, and as a result, in Shen Yun's smile, his heart was full of despair - where was there any word on Shen Yun's screen. Even the on-screen icons and wallpapers are completely different.

Could it be that I just hacked into a fake system?

The onlookers also screamed one after another, and then asked Instructor Zheng: "Instructor, what is going on?" We clearly saw Yang Dedi already writing on Shen Yun's screen just now. But why is there no one on Shen Yun's computer? ”

In the noisy questioning, Instructor Zheng coughed lightly, and then shouted solemnly: "Be quiet." ”

The students quickly closed their mouths, and even Yang Dedi didn't dare to shout loudly anymore. At this time, Instructor Zheng looked at Shen Yun with a smile on his face: "Shen Yun, tell me, what's going on?" ”

Hearing the instructor's order, Shen Yun quickly said in unison: "Report to the instructor, students, in fact, what Student Yang invaded just now has always been a fake system. This is a mirror image that I made by a technical means. ”

"In this image, the intruder can play with whatever he wants, but it doesn't have any effect on the computer itself. Conversely, if some surveillance is used, it is possible to reverse detect the intruder's address. ”

"And the specific means of operation are like this. At the time of my invasion, I had already taken control of Instructor Zheng's console. In the console, I changed the parameters inside. That includes my IP. ”

"Of course, Yang also found out that I had done such a thing, so he screened these IPs. Then I concluded that the last IP was my address. Actually, he didn't know that the second one was real, and everything else was fake. ”

"Every fake address is a channel that I have created virtually, and there is only one end point, and that is the honeypot system I made."

Shen Yun tapped a few times on the keyboard, only to see the big screen on the podium suddenly lower, and then the projector turned on automatically. On the screen is Shen Yun's computer desktop.

I saw the mouse point to one of the files and add it, and when I clicked it, it was all the operations of Yang Dedi in the honeypot. After playing these, Shen Yun opened another text again. There is a dense code on it, mixed with a lot of numbers.

Seeing this, Yang Dedi felt as if he had suffered a heavy blow and was deflated.

At this time, Instructor Zheng took over Shen Yun's words and continued: "These are the mission logs generated by Yang Dedi during the invasion. I have to say that this contest is wonderful. ”

"But Shen Yun, if Yang Dedi chooses the second one, which is your real IP, will it be like this when he takes over?"

Hearing this, Shen Yun shook his head: "In fact, if he can catch up here, what awaits him will be the overclocking of his computer, which will eventually cause serious wear and tear on the hard disk, and in a wisp of smoke, the computer will stop." ”

At this time, Instructor Zheng had no doubt that Shen Yun was bragging. Because through a series of previous indications, in the area of hacker attack and defense, Shen Yun's level definitely surpasses himself by much.

"You see, this is a wonderful hacker battle to attack and defend. Although Yang Dedi failed twice, it has to be said that his level is still quite high. ”

"With the modernization of the troops, the application of high-tech means in the army has become more widespread. Contemporary military personnel, while possessing excellent military qualities, should also continue to learn high and new technology. Only in this way will we be able to keep the enemy out of the country in future wars. ”
