What does a girl do when she finds out that a man is spying under her collar?

The shy ones screamed "ahh A little more violent, he slapped it with a "snap", and then scolded fiercely: "You dare to peek at the old lady? ”

And what about Gao Xiaojie?

This woman is neither shy nor violent, a little eccentric and a little flying. Then she asked very calmly, "Is it good-looking?" ”

Chen Xu subconsciously replied: "It's good-looking!" ”

As soon as he said this, Chen Xu knew that it was over, and sure enough, Gao Xiaojie looked at him with a sneer. Chen Xu smirked: "What, you must have just taken a shower, it must be very hot, do you want to eat ice cream?" What flavor do you want to eat? Strawberry or creamy? ”

Gao Xiaojie smiled and said what did you see?

Chen Xu hurriedly shook his head and said I didn't see anything! Then looking at the girl's eyes, he unconsciously lowered his head, and said timidly: "That...... The white clothes were in the way. ”

Gao Xiaojie asked again: "Then do you want to see what is inside?" ”

Chen Xu wanted to say it, but he knew that he would be shot to death if he said so. So he shook his head and said, "Well, I don't want to." ”

"You're interested!" Gao Xiaojie didn't pursue much, and gave him a blank look: "Say be honest next time, forget it this time, this girl herself is not careful." Then she ran to the box and hugged her notebook, and her bare little feet gently kicked Chen Xu and said, "Let go to the side, I don't have any eyesight, this girl is coming to catch the thief." ”

"Catch a thief?" Chen Xu gave up a place for her, and then handed over an extra network cable - because he also brought the router and network cable in the dormitory, so four computers could be connected to the network cable at the same time.

Seeing that Gao Xiaojie opened a software that he hadn't seen before after turning it on, Chen Xu asked what you want to do?

"Give me the IP address of the server with the virus, hum, dare to spread wild on this girl's land, I really don't want to live!"

Seeing her scanning the IP port, Chen Xu reacted and said, "It turns out that you want to hack him!" Will you still invade? ”

Gao Xiaojie smiled proudly: "Of course, this girl just worshipped the master of the master." Just use this guy to practice his hands! Well, look at your virtual system, I didn't expect you to play this stuff too? ”

Chen Xu snorted: "I'm still more interested in antivirus, then you deal with this server slowly, I'll break the shell of this virus, and then make a special kill." ”

Hearing this, Gao Xiaojie's eyes widened a little again, because it was not so easy to solve a virus. Do it yourself? That means that Chen Xu's programming ability is already quite level, but thinking about how easy he was when he took the C language test, it is estimated that he had studied it before when he was not in college, so there is a limit to being surprised.

In fact, it is not difficult to kill this virus, because the virus is also a kind of program and has a fixed route.

Under the virtual system provided by Xiao Min, every move of the virus is completely under Chen Xu's monitoring, including how to replicate, where to insert it, which key value of the registry has been modified, and how to open it, etc., are completely under Xiao Min's monitoring.

This virus is very simple, it is nothing more than replication and infection, and then modify the boot options of the registry, at most plus infiltrate the key processes, so that the virus can continue to be resurrected after being deleted through the regular mode - these things are very simple to kill, not to mention using special killing, even if it is a person who generally understands a little computer knowledge, after entering the security mode of the system, it can kill itself, it is really a very simple thing.

Such a simple virus can only be described as ordinary, Chen Xu just used it to practice his hands, but let the system analyze the details of this virus first, such as what will happen when it is attacked, and so on. Then Chen Xu was bored to watch how Gao Xiaojie invaded.

Gao Xiaojie's software Chen Xu had never seen, but after a few glances, Chen Xu immediately knew that this software was the same as his own, integrating vulnerability scanning, handshake programs and other common hacking techniques. It's great for entry-level hackers, but it's pretty rudimentary for higher-level hackers.

However, seeing Gao Xiaojie's attack method, this made Chen Xu very eye-opening.

Chen Xu has always learned from Xiao Min, and the attack method is the most conventional one. Request a connection, bypass the server firewall, and obtain administrator privileges...... It's basically similar.,The method is very simple.,Although it's simple.,But it's easy to be discovered by the other party and fight back.。

When Gao Xiaojie attacked, she asked for a connection here, and the scene was sufficient, but she silently disguised the data stream from another port. It's like a thief sneaking into someone's house, first asking an accomplice to knock on the door openly, and when the owner is focused on the door, she sneaks in through the back window.

Although this attack method is not very novel, it makes Chen Xu immediately have a mental understanding of attack and defense invasion.

Judging from Gao Xiaojie's work, her level is actually not as good as herself. She is not very strong in terms of her ability to respond to data flows and her proficiency in the use of various instructions. This is probably because Gao Xiaojie's basic knowledge is not solid enough, at least compared to Chen Xu is not solid - these basic knowledge is nothing more than the understanding of computer and server software and hardware and the operation system, Chen Xu has studied the Chinese language for several months, although he has only learned some scratches, but the kind of easy-to-understand language has made Chen Xu impressed after learning, not only learning, but now he can also reach the level of learning for his own use.

Seeing Gao Xiaojie's tricks, Chen Xu finally understood why Xiao Min refused to teach himself hacker attack and defense techniques, because although hackers' attack and defense seem boring to outsiders, it is undoubtedly an art for the hackers themselves. And the category of art can never be solved by reading from the script. Looking at Gao Xiaojie's attack methods, in fact, there are only a few commonly used by ordinary hackers, but the problem is that her weird and changeable ability can bring her original skills into twenty points!

Chen Xu made such a judgment in his heart.

Gao Xiaojie's basic technology is probably only ten points, and he has fifteen points, but if the two sides use the same hardware, the probability of losing should be very large, and if he loses, he will lose in his work.

Chen Xu couldn't have imagined that there would be so many changes in the way of camouflage data flow before, and he should be able to think of Gao Xiaojie's offensive method, but in fact, this kind of "thinking" is the most difficult.

There is a saying called "nothing can't be done, only unexpected", as if Watt invented the steam engine when he saw the lid of the boiling kettle being opened by steam, and Newton discovered the law of gravitation when he was hit on the head by an apple. Chen Xu felt that his imagination was indeed restrained, he saw that the lid of the boiling kettle was opened by steam, and he would only re-close the lid of the kettle, and if the apple was smashed on his head, he would eat the apple directly.

Hacking techniques are the same, compared to Gao Xiaojie's weird and changeable, Chen Xu feels that his offensive method is too simple.

So Chen Xu asked: "Who did you learn this way of attacking?" ”

At this time, Gao Xiaojiezheng had already obtained the management authority and began to obtain the other party's IP address, because this server was obviously just a springboard, and the other party was managed through remote control like himself. So at this time, Gao Xiaojie said a word very casually: "Jing ......"

Then she reacted immediately, laughed and said, "After many experiments by me, how about creating it myself, it's very good, right?!" ”

Her words were obviously trying to cover up, and she said the word "crystal", which immediately reminded Chen Xu of Zhanjing. The girl with light blue hair, the girl who has been quiet.

Thinking of what Zhan Jing said to himself when he was eating buffet, Chen Xu asked tentatively, "Zhan Jing?" Her technique is good? ”

Gao Xiaojie waved his hand again and again to cover up: "Oh, no, don't ask!" Oops, oops, let that guy run away! It's all your fault! ”

Chen Xu looked at the picture, and sure enough, she had lost the trace of the other party, maybe she was run away by him just now before she had time to find out the other party's real IP when she was nervous. Seeing Gao Xiaojie pouting with an unhappy face, Chen Xu smiled and said, "Forget it, it's just a little thief." ”

"It's simple!" Gao Xiaojie puffed out his cheeks cutely: "This is the first time I've officially fought with someone, and I really don't want to let him run away like this!" Oops, it's all you, you have nothing to ask me that question, okay, okay, it doesn't hurt to tell you, Jingjing's level is very high, and I learned everything from her now. But you can't spread the word. ”

"If I don't spread it, I will not spread it." Chen Xu waved his hand again and again and said, "Uh, then can you teach me?" I want to learn too. ”

Gao Xiaojie looked at him and said You also want to learn? Okay, let's go to assembly language first.

Chen Xu smiled and said: "I have a certain foundation for those things, my worst thing now is my hands-on ability, your hands-on ability is very strong, teach me, see that I am so generous to take you in, even the bed is given to you." ”

As soon as he said this, Gao Xiaojie really had no way to refuse, and was about to speak, when he suddenly pointed to the screen of Chen Xu's computer and shouted: "Oops, how did your system become like this?" ”

"Which one?" Chen Xu looked back and found that on the screen of the virtual system he opened, all the application file icons had turned into a shape.

A black and white panda holds the shape of three sticks of incense.

"Panda burns incense?"
