Reshaping life starting from the Junior Class of HKUST

Chapter 73

Several people looked at Wu Zhe who was typing on the keyboard quickly, and saw that his hands had been connected into afterimages.The characters on the screen are appearing and wrapping rapidly.Huang Minghai and Wang Chao couldn't keep up with the rhythm anymore, but Shen Zhiwen was better, barely able to keep up.

"Hey, Ah Zhe, how did you discover this loophole." Shen Zhiwen waited for Wu Zhe to finish typing, and asked immediately.

"I found it by chance, but I didn't expect it to be useful one day." Wu Zhe explained.

Seeing that everyone was full, he clapped his hands and said, "Let me tell you about my plan, and ask if you don't understand. Now we must lose in the defense battle, but there is a saying in the art of war to encircle Wei and save Zhao. It's too late to save now. Then let’s die together! Pull everyone on the same starting line.”

Seeing that Huang Minghai and Wang Chao still didn’t understand, Wu Zhe explained: “What I wrote was a worm, targeting a logical loophole in TCP/IP itself. Its purpose was only to paralyze the server. Since our server was hit , as long as theirs can’t get better, then it’s not considered a loss.”

"Azhe, this is——" Huang Minghai didn't say anything later, but Wu Zhe understood that attacking the University of Science and Technology forum at the same time is a law that does not blame the public. Now there are only a few of them. If someone finds out, they will be in trouble .

"I'm afraid of a fart, I'll do it." Wang Chao obviously reacted.

Shen Zhiwen also nodded.Wu Zhe looked at Huang Minghai.Huang Minghai thought for a while, and then nodded vigorously. He is calm, but he definitely has a bit of ruthlessness at critical moments.

"Okay, then I will divide the work. Zhiwen, you find peripheral broilers, try to find foreign ones, the more the better. Then assign them to us, I will come from the c9 alliance school, and Wang Chao from 211 will go. Then you are the boss. Foreign countries choose targets at will, and the purpose confuses the sight. Let's start!" Wu Zhe said with a wave of his hand.

Several people picked up their laptops and started to operate. Fortunately, these people's family conditions are not bad.Laptops are all bought with high configuration, and the speed is very fast.

As soon as Wu Zhe surfed the Internet, he felt that the hotel's Internet speed was okay, so he immediately went to the broiler to change his IP address, and then came back halfway around the blue star.Then I sent the program I wrote to Wang Chao and the three of them.At this time, Shen Zhiwen was also ready.For a computer player like him, he usually has broilers prepared by himself. This time, not only has he circled a lot, but he has even brought out his previously hidden old books.

When the port scan started, Wu Zhe just used SYN and a worm attack written by himself.

Use the computer's handshake protocol to get into action.A connection is established using a three-way handshake.

The first handshake: When the connection is established, the client sends a syn packet (syn=j) to the server, and enters the SYN_SEND state, waiting for the server to confirm.

The second handshake: the server receives the syn packet, must confirm the customer's SYN (ack=j+1), and at the same time send a SYN packet (syn=k), that is, the SYN+ACK packet, and the server enters the SYN_RECV state;
The third handshake: The client receives the SYN+ACK packet from the server and sends the confirmation packet ACK (ack=k+1) to the server. After the packet is sent, the client and server enter the ESTABLISHED state and complete the three-way handshake.

When the link is completed, the worm also enters.

Then one, two, three...

Wu Zhe didn't release the virus immediately, and waited until Wang Chao and others were ready.Then he shouted: "One, two, three actions."

Everyone hit the Enter key at the same time.

Regardless of the result, Wu Zhe started to tidy up the battlefield and tail.Because he ran away after the fight, the opponent had no time to react.So it seems pretty safe.

Wu Zhe thought for a while and said: "Boss, Zhiwen, you left your computer, and now go back to your room to sleep. Just pretend you don't know about it at all, and I will deal with the computer later. I will buy you a new one when I return to Feicheng."

Both Huang Minghai and Shen Zhiwen nodded, knowing that they had gone too far.Without saying a word, he turned and went back to his room.

"Give me your computer too." Wu Zhe put away Huang Minghai and Shen Zhiwen's computers and said to Wang Chao.

"Take it! I just want to change it." Wang Chao didn't care much.

"Well, go to bed first! I'll go out and download. I'll be back later." Wu Zhe put the four computers in his backpack and went out.

Wu Zhe went outside, found a secluded place, and smashed the four laptops to pieces.Another unknown river was found, and the parts were thrown into it separately while there was no one there.

Back in the room, Wang Chao had already fallen asleep.Wu Zhe didn't call him, and went to bed after washing up.

These people are asleep, and the colleges and universities outside are very lively.My own forum server was beaten down by a virus.

Various schools have already organized people overnight to analyze and crack.Even some network security companies were alarmed, and this virus also appeared abroad.

The good news is that this time the virus is not contagious, it is just a point-to-point attack.It may be some hackers' joking reminder of computer vulnerabilities.

Some students from Shuimu University majoring in computer science joked: "This is really God helping those people from HKUST! I wanted to humiliate them, but I didn't expect us to be finished. I just called to confirm that there are 70.00% of the universities. Hit the trick. Come on, don’t laugh at the second brother now, everyone is the same.”

"Do you think it is the ghost of the University of Science and Technology?" another said.

"Do they dare? What is the nature of this? It's not like you don't know! Besides, you can fight back after you've been beaten to the ground. Why didn't you fight back in the first place?"

"Okay, don't talk about it. Hurry up and work! If we don't make it right tonight, we will lose face tomorrow."

Several people stopped talking and started working.

This has almost become the same scene in all colleges and universities.It's just that Wu Zhe's worm is so easy to crack?

------

The next day, several people got up early and went to the restaurant to have a buffet breakfast with Fu Zhoumin and the others.When Fu Zhoumin saw Wu Zhe, he waved to him, and Wu Zhe was also very well-behaved.After taking eggs, milk and bread, he sat beside Fu Zhoumin.

"Mr. Fu, I'm sorry. I embarrassed you." Wu Zhe apologized as soon as he sat down.

Fu Zhoumin shook his head and said: "I don't think so, but I feel that you have won glory for us. Who has never been young and energetic, and young and admired. I appreciate your vigor. Now that the gauntlet is under, you know ?”

"Qiu Award, I heard about it." Wu Zhe replied.

"Happy victories are not allowed to lose!" Fu Zhoumin said with a smile.

"I won't lose." Wu Zhe said with affirmation.How can I lose, I promised her to be the brightest star.

"That's good. After eating, go back and pack up and we'll go back to school."

After everyone finished eating, they went upstairs to pack their luggage.Depart from the train station and return to HKUST.

Arrived at Beijing Station.Wu Zhe was about to enter the station when he suddenly felt something.

Turning around, a woman stands behind Tingting.Who else is it not Tang Meng?

"Wu Zhe, let's go in first." Fu Zhoumin said.

"Thank you, Mr. Fu, I'll come later." After Wu Zhe thanked him, he came to Tang Meng.

"Why are you here!" Wu Zhe asked.

"I still want to see you off." Tang Meng said with a smile. "Otherwise, I will have to see you again with Qiu Zhi."
