Bit Mania [Hacking]

Originally, Zixin planned to visit Xingchu when he had nothing to do in the future, but his integrity value had been exhausted after this incident. In order not to turn himself into a voyeur, he thought it would be better to restrain himself in such matters.When he crawled back to the chat room resentfully, he found that hundreds of chat records had accumulated in it.

Octo: What are you talking about, so happy?

Linux: Oh God!

Roger: Great God is coming!

Roger: We thought of a way to clean up the interior!

Octo: ... Let's hear it.

Roger: Your cooperation is needed!

Octo: Why do I have a bad feeling...

Linux: No, no, absolutely nothing, just please radiate your light and heat a little bit!

Mild: ...In fact, this is the case. We decided to carry out real-name authentication for all existing volunteers and let them register as members, so that they can get their personal information, and it is easier to check for spies. With this set of authentication System, it will not be easy for spies to sneak in in the future. Similarly, as registered members, they will get corresponding rights.

Afier: Yes, the first step of the real-name authentication operation requires you to complete it!

Octo: How?

Vogt: Exam papers!Let them take the exam on the surface, but actually collect personal data.Of course, we will keep these materials the strictest confidentiality, and will never violate people's privacy, let alone leak them out.

Afier: After passing the test, you can have a general understanding of the strength of the volunteers. If a company using our system needs manpower, it can also arrange for the right people to go, killing two birds with one stone.

Roger: Oh god, the two kernel designers who are most suitable for this set of Linux system exam questions are you and Linnaz. Linux is now adrift and has no fixed place. I am afraid I don’t have the time and energy to do this. OK, so only you.

Octo: Can I still refuse?

Everyone said in unison: No!

Luo Zixin turned off the computer angrily, stood up from the chair, and said to Zheng Xiu, "It's time for me to go to class."

"En." Zheng Xiu lazily replied, and asked casually, "What class?"

"Cognitive Practice."

"what?"

"Cognitive practice," Zixin said, "Do you still remember Professor Yao Yizhi, who took us to the school's computing center today for a cognitive class and introduced various computer equipment."

Zheng Xiu seemed to think of something, and the expression on his face became a bit dark and difficult to understand: "I will go too."

Zixin turned around and said, "According to the professor, the things to visit this time are quite confidential. You are not from our school, so it would be a bad idea to go there, right?...Uh, how about I go and ask for you?... "

The result of asking about it was that Yao Yizhi thought about it and said: "Since Zheng Xiu doesn't understand computers, it's okay to come and play, but after today, you must never talk about this matter with others, let alone tell what you have seen and heard. come out."

"Don't worry, it won't."

The cognitive class was taught by a few students from the computer school in the first-year junior class, including Zixin and Zheng Xiu, a total of six people, who followed the college students. There are a lot of college students, and the computing center cannot have so many people at a time. In order to ensure the quality of teaching, Professor Yao Da led the team in batches. He walked at the front of the team, like a tour guide taking people to a museum, explaining all the way.

"Zixin," Zheng Xiu walked behind, and casually pointed to a direction that Yao Yizhi hadn't introduced yet: "Do you know what that machine does?"

Zixin took a closer look, and quickly replied: "It should be a network intrusion detection and prevention system platform. Running IDS or IPS on it can perform signature, protocol, and anomaly-based detection... and so on."

"Can you understand what the professor didn't say?" Zheng Xiu asked, "How much can you understand about the equipment here?"

"Most of them can be guessed at a glance." Zixin did not doubt that he was there, and looked very excited: "I didn't expect there to be so many special-shaped computers before, and I have learned a lot today... But, now After looking all the way, I found that these things are actually just a high-performance computer, but they have different emphases and are loaded with different systems, so they have different uses... Zheng Xiu, why are you suddenly interested in these things? Interested, want to learn computer?"

"I don't want to." Zheng Xiu smiled and shook his head, looking very happy.

The other party's expression was different from usual, so Zixin couldn't help but look at it a few more times.Unexpectedly, Zheng Xiu always had a straight face and was extremely serious on weekdays, so it turned out that he smiled like this.

"What are you talking about, so happy?" At this time, Yao Yizhi had finished the introduction, distributed the experiment guide to the students, and asked them to do cognitive experiments in groups, while he himself was free, walked up to the two, and handed a copy of the guide to the students. In Zixin's hand, he pointed to a server in the middle of the laboratory: "This is yours, don't mess it up, remember to write the experiment report."

"Yeah!" Zixin's eyes lit up, there was nothing better for him, he was like a mouse that fell into a rice bowl, and disappeared in a flash.

Yi Zhi shook his head with a broken smile, and turned his gaze back.

Zheng Xiu had put away his smiling face at this time, pretending not to see Yao's eyes, and was going to go around to find Zixin, but Yi raised his hand, blocking his way.

Zheng was thinking about it, but he still asked knowingly on his face: "What's the matter, Professor Yao?"

Yi Zhi withdrew his hand, looking a little embarrassing: "I... don't mean to embarrass you, I just want to ask... how is that idea going? Of course, it doesn't matter if you don't want to say it."

Yao Yizhi asked this question, but it was already a bit abrupt.Academic achievements are directly related to the honor of a scientist's life, especially for a group of people who are at the forefront. Maybe just a little achievement can make their names be included in textbooks, and even affect the entire national strategy, even the world pattern .Therefore, when scientists ask about academic progress, let alone colleagues of different nationalities, even among colleagues belonging to the same unit, they are secretive.But the conjecture argument that Zheng Xiu mentioned to him last time is another big problem in his field. After Zheng Xiu left that day, Yi Yi thought for a long time by himself, and finally his thirst for knowledge overcame everything, so he put down his old face in the field. Ask here.

Of course, in fact, he has no malicious intentions, but as a scientific researcher, he is more or less obsessed and fanatical. If it was someone else, he would not ask, but Zixin Zhengxiu is a child, facing them Sometimes people will unconsciously let go of the twists and turns between some adults, and replace them with simple seeking of knowledge and simple caring.

"That..." Zheng Xiuhun said indifferently: "I have already demonstrated it, you want to know? Then I will send you the academic paper later."

"Thesis?!" Yao Yizhi was surprised: "Have you published it on other platforms? How come I don't know about such a great achievement..."

Zheng Xiu is best at two expressions, one is serious and the other is innocent. At this time, he is full of innocence: "It hasn't been published yet, and only I know the proof."

"How can you just give me something that only you know? Do you know how valuable that thing is?!"

"I know," Zheng Xiu said, "I think if it's Professor Yao, it's okay to leave it to you, and I don't care anyway."

"...No, don't care?!"

"Professor Yao, it's time for get out of class to end." A student came to Yi Zhi's side to remind him in a low voice.

Yao Yizhi recovered from the shock and looked at Zheng Xiu again. At this time, the latter had found Zixin. The two boys made a goodbye gesture to him, put the finished experimental report on the middle table, and went out of the computing center.

The students left one after another. He collected all the report papers and started correcting them in the empty computing center. When it was his turn to write Luo Zixin's name, he unfolded the paper and saw that it was written in small, correct characters. It is full of dense experimental parameters, and it describes in detail the working principle of this server, the structure of software and hardware, shortcomings, and advantages. A series of intrusion methods and corresponding improvement methods—for this large server worth more than 2000 million dollars, the storm in his heart has long been unable to calm down.

"That's why you... don't care."

He finally understood the bitter feelings of those teachers who had a heart attack on the podium.

In the next few days, Zi Xin was busy preparing exam papers. He had no experience in this kind of thing. Start your pen.

After class that day, he tidied up the papers on which the test questions had been written in the dormitory, and stood up to pack his things.

"Going to accompany your little love again, the cheese cookies from last time were delicious, I want more." Hai Tian sat back on the chair and teased him maliciously.

Zi Xin pressed his protruding face back: "Get out, Zheng Xiu is in a good mood to give you something to satisfy your hunger, but you are still addicted to it."

"Tsk, you ruthless guy..."

"I'm leaving!" Zixin broke Xue Haitian's fingers holding onto his clothes one by one.

"Cookie! Cookie!" Haitian grabbed it with one hand, "If you don't take it for me, I will report you for living together and not coming back at night!"

"Hurry up and report it. If you don't report it, you're a puppy."

A slender and tall figure walked out of the gate of the administrative building of the School of Computer Science. Her shoulder-length black hair was smoothly scattered in the breeze and reflected light slightly in the setting sun. She was a very beautiful young woman with not too big eyes. , but relatively long, with a straight nose, a little makeup, wearing a long winter skirt and high heels, and a small white jacket on the upper body, which looks very charming.When the passing male college students saw her, they unconsciously slowed down, their eyes full of amazement and fascination.

"...Wow, who is that beautiful woman?"

"You don't even know Zhou Xiao, are you stupid when you study? That's a new graduate student from the School of Computer Science, and he became the beauty of our school right away!"

"School belle? Then why don't you see her often..."

"Yeah, she is a very mysterious beauty. It is said that she lives off campus. No one can figure out where and when she will suddenly appear, but every time she appears, it is amazing..."

I saw a woman named Zhou Xiao who seemed to be shyly lowering her head, walking with a stack of A4 papers in her right hand. She was just about to turn around a teaching building. Maybe it was because she kept her head down and looked down. , didn't notice the movement from the other side, collided with the oncoming person, loosened his unbalanced hands, the paper in his hand and the paper held by the other party fluttered in the air, and then scattered all over the ground .

Zixin felt as if he had bumped into an iron plate, and after being on the ground for a while, he got up with the help of others. At this time, there were already many people around the two of them, and two boys wanted to go Fu Zhouxiao was avoided by her without any trace.

"I'm sorry, I left in a hurry." Zixin apologized first, and wanted to squat down to pick up the papers scattered on the ground, but when he saw the other party clearly, he was stunned, and looked at Zhou Xiao dully.

Zhou Xiao bent down to tidy up, not noticing his strangeness, and when he spoke, his voice was full of magnetism: "I should say I'm sorry, I didn't pay attention to my walking, and I couldn't avoid it in high heels."

"Here." Others helped gather the paper and handed it to them.

"Thank you." Zhou Xiao smiled gratefully at the boy, which immediately made him blush. She seemed to be used to this, so she stood up and walked away with small steps.

"... Hey, what are you looking at, are you fascinated by the beautiful senior?" Someone handed the paper to Zixin: "Little friend, be careful when you walk in the future, if you don't meet the gentle-tempered Zhou Xiao, Then you can’t eat and walk around.”

"Pretty...senpai?" He stretched out his hand to take it in a daze, his expression seemed distorted for some reason.

Putting this episode behind the scenes first, Zixin walked across a street and came to Zheng Xiu's house.

"There is a product tasting meeting tonight, let's go together." Zheng Xiu suggested.

Zixin hesitated for a moment, and said, "The test papers for Roger are out, and I have to enter them on the computer."

Zheng Xiu waved his hand: "What am I supposed to do? Is it to transcribe handwritten manuscripts into the computer? It's easy to handle. You just have to play with me tonight... No, go try the food tasting. I will get the paper later in the daytime." Just do it for you when you are free. By the way, last time I gave those snacks to your roommate, how was the response?"

Someone thought about it, so he handed the written question directly to Zheng Xiu: "Xue Haitian said that the cheese cookies you gave him are delicious, and I want more."

"More?" Zheng Xiu said: "That's simple, ask him to come together tonight and eat enough."
