Hu Yifei waved his hand and said with a smile: "How can I understand this, isn't this asking you for advice!" ”

The other party was deducted a big hat, very happy, anyway, there is still a period of time before the start, seeing that Hu Yifei looked like he was sincerely seeking advice, Suo surnamed boasted with him, "From a technical point of view, there are some preparations to be made before a hacker attack, and the most important job is to hide the real IP." ”

Hu Yifei waited for this, and hurriedly asked: "Then what do you need to do to hide the real IP?" ”

"Usually you use a springboard server!" The guy from Nongda was very kind, took out a piece of paper, and drew a picture for Hu Yifei, "For example, if you want to attack a machine, assuming that it is A, in order not to expose yourself, the master will generally log in to the machine B first, and then log in to C from B, from C to D, and so on many times, and finally it may be on the X, or Y, the machine to launch an attack and invade A." ”

Hu Yifei understood, this is the same as logging in to the school's server with an artifact, and then logging in to the wolf's den forum from the server, but others have gone around many more circles than themselves, and they go around in circles to go to the wolf's den, and others go around in circles to attack.

"Theoretically, the more springboards are used, the longer the chain, and the safer the attacker will be." The guy from Nongda lifted his glasses, "But due to the influence of network speed and efficiency, this chain cannot be infinitely long, and generally two or three springboards are enough." Therefore, the real master attaches great importance to the choice of the springboard, and the springboard does not necessarily have to be a computer, the master will add a router or switch to the springboard, do you know why? ”

Hu Yifei shook his head like an idiot, "I don't know, why?" He was still surprised, can the router still hack? In his impression, that thing was a square box with a network cable, and he didn't even have a screen keyboard, and he didn't know if it was equipped with a system, so how could it be hacked.

"Because the chronicle on the router, once it is cleared, it can no longer be restored, and after the chronicle on the computer is cleaned up, there is still a way to restore it!"

Hu Yifei was taken aback, no wonder someone could track him, could it be that someone else cleaned up his own Zhizhi again? Thinking about it again, Hu Yifei felt that it was wrong, it was really strange that he would not leave a legend when he used the artifact, and he still didn't understand how the bird god found himself.

"What? Can routers hack too? Hu Yifei looked at the guy expectantly, "Brother, do you have a springboard for the router, can you show me what it looks like!" ”

The guy from Nongda was suddenly a little impatient, and waved his hand, "I didn't see that I was busy with Nandian's affairs, how could I have time to show you this!" ”

Hu Yifei was not discouraged, and begged with a shy face: "Master, you can get it, let me also have a long experience, get a springboard, you can also use it when you attack later,!" ”

"What a springboard!" The people from Nongda turned around and looked at the computer, and muttered: "To deal with Nandian, you don't need a springboard at all, you have to let them know very clearly that we did it!" ”

Hu Yifei couldn't do it, leaned over and squeezed around, and looked at the screens of the thirty masters, and according to the results of visual inspection, there was really no one using the springboard. The masters seem to have made preparations at this time, log on to QQ, look at the web page, and there are four or five of them who are busy stealing vegetables on the farm, and they can't access the Internet for a day, and it is estimated that these masters are also suffocated.

Looking left and right, it was still the master of the Agricultural University who was the most serious, and he clicked on the latest pure English safety report on a security website, and looked at it very seriously.

Hu Yifei lowered his voice, and then bothered the master of the Agricultural University, "I took a look around, or brother, you are the most professional!" ”

The master of the Agricultural University proudly lifted the frame of his glasses, but said modestly: "I'm still far behind, not a professional, Kevin. Mitnik is my target! ”

Hu Yifei smiled, "You are too modest, that professional hacker, what else should you pay attention to when you invade except for a springboard?" ”

"That's a lot!" When the farmer heard Hu Yifei ask, he had another conversation, "Making a springboard and cleaning up the Zhizhi are the most basic." Professional masters generally do not use their own computers to invade, but will choose some public machines with a relatively large flow of personnel. ”

"Like an Internet café?" Hu Yifei asked rhetorically.

The master of the Agricultural University nodded, "Exactly!" ”

Hu Yifei wondered, no wonder these people were selected to choose, and finally chose the Internet café, but this Internet café is equipped with cameras.

"Of course, you can't find an Internet café, and you can use a virtual machine system, you know?"

Hu Yifei shook his head, "I don't understand!" ”

"Go back and download one online, and you'll understand it by researching it!" The master passed this question, "When you log in to the springboard, you have to see if there are other intruders on that machine, and it is also taboo for hackers to grab someone else's springboard!" ”

"How can I check if there are any other intruders?" Hu Yifei understood a little that he was being tracked by the bird god, and maybe he was discovered like this.

"There is an order, called ......", the master milk has been special for a long time, but the one behind can't say it, his face is a little embarrassed, and he patted his head, "I usually use it all the time, but when I say it today, I can't remember it!" I'll check it for you! After the master finished speaking, he turned off the English report, logged in to his blog, found a reprinted "Hacker Intrusion Instructions", opened it and looked at it twice, and said: "user, showuser, you remember these two commands!" ”

Hu Yifei was frightened by the other party's "milk oil" and "beast oil", he glanced at it casually just now, and actually saw what was written at the back of the article, which seemed to be the same as what the master had just said, and he chuckled in his heart, this master will not be a master of paper talk, right? Hu Yifei suddenly lost interest in asking questions, ran back to sit on his machine, opened Nandian's website and looked at it, and found that Nandian's people were laughing: Don't say it's eight o'clock, we may not be able to stop attacking at eight o'clock tomorrow, if you have any means, just let the horse come.

At half past eight, the black-clothed boss beckoned, "Since the other party doesn't give face, let's not be polite, the attack begins!" ”

The people in the Internet café suddenly squeezed forward, wanting to see what the hacker attack looked like, the fourth child was originally sitting in the front row, at this time a lot of people suddenly appeared in front of him, blocking his view, the fourth had to stand on the chair and look down, the boss was too fat, standing up to be reimbursed a chair, so he had to tiptoe forward and stretch his neck.

Hu Yifei looked at it and found that the attack methods of the thirty masters were really different, they all ran the tools they had prepared before, and then they stared at the screen very seriously.

Everyone watched it for a long time, and couldn't understand what was going on, and said that staring at the screen could disconnect Nandian from the network, so they shouted: "How is it?" What are you attacking now? Is Nandian's network down? ”

The black-clothed boss was running a scanner, stood up and said, "Don't worry, it's not so easy to attack, you have to find a loophole before you can attack!" We have a complete battle plan, the first attack is the opponent's website, and after a while, everyone will be able to see that Nandian's website cannot be opened! ”

Saying this, the crowd dispersed a lot, and they all went to their respective computers to refresh Nandian's website back and forth to see if there were any signs of being attacked and hung up.

At this time, the people of Nandian were already extremely sarcastic on the forum, "Dongyang masters, isn't the earth there turning, is it still at 8:29?" "Of course, the earth is still turning, but it is the people's watch who chooses to stop moving! ”

The people in the Internet café were furious and began to hit the keyboard to fight back, "Get paper towels ready, don't wipe your underwear wet when you disconnect from the Internet for a while!" "It doesn't matter if your underwear gets wet, but don't get the computer wet, it will short-circuit!" ”

When everyone fought back, they hoped that the master would quickly kill the opponent's website and get angry, but an hour had passed, and the opponent's website was still alive, and the strength of everyone's counterattack gradually weakened, almost nothing. The grumpy gentlemen have already begun to scold Huai: "Damn, it's been enough to build a computer for so long, can it be dark!" ”

The boss also slapped the keyboard, "Say, wait for an hour, it's enough for Lao Tzu's next copy!" ”

Hu Yifei is somewhat understanding, thinking that he is probably going to be disappointed today. The master of the Agricultural University is quite reliable,Ran an automatic attacker,As long as you fill in the opponent's IP, you can automatically make the opponent's machine blue screen of death,IP address is also against it,The tool is not useless,It's just a point,The object of the attack must be the win98 system。 But that kind of antique system, Hu Yifei has never seen it since the day he used the computer.

After a little more time, the voices of everyone's doubts became louder and louder, and the boss in black couldn't stand it anymore, sweat began to appear on his forehead, and he turned his head to discuss with the heads of other schools what to do.

The boss of the School of Political Science and Law muttered to his younger brother for a while, "My brother said that he has a tool, which definitely works!" ”

The boss in black hurriedly gave up the hot ass seat, "Let him try!" ”

The little brother was very proud, went over and sat down, took out the USB flash drive that had been prepared a long time ago, plugged it in, found a tool, filled in an IP, and then clicked the "attack" button.

"That's it! Nandian's website can't be opened! Someone immediately shouted.

Hu Yifei hurriedly turned around to refresh the web page, and sure enough, Nandian's website couldn't be opened, damn, artifact, Hu Yifei was overjoyed, thinking that even if it was soft grinding and hard bubbles in the past, he must get that person's tools in his hands.

There was finally a cheer in the Internet café, and everyone roared: "Nandian's grandson, now you know how powerful your grandfather is!" ”

"Number 127! What are the people in machine 127 doing? The radio in the Internet café suddenly heard the angry roar of the network administrator, "Damn, the Internet café was attacked by you and disconnected!" ”

Everyone was dumbfounded, and then went to refresh the web page, only to find that not only the Nandian website, but all the websites could not be opened. Subsequently, the voices of "I say", "I rely on" and "I" came and went in the Internet café, and many people were kicked out of the game.

The network manager rushed over and grabbed the guy on machine 127, "What are you doing!" ”

"I ...... I'm attacking the Nandian website! "That little brother has a really good quality in his heart, and he is still not flustered at this time.

"You attack a hammer!" The network administrator clicked on the tool running on the desktop, "You are blind, can't you see the name of the tool?" LAN ARP attacker, damn, LAN and WAN can't be distinguished, and it's a fucking master, hammer! ”

Everyone was in an uproar, and then they scolded, what a fucking waste of feelings, the white rooster moved all night.

The owner of the Internet café was blushing at this time, and he was overjoyed, he provided the machine for free, but he didn't invite someone to attack his Internet café, and said at the moment: "At this level, you dare to come out and be embarrassed, don't want to be a network administrator here!" ”

A group of masters turned red and walked out of the Internet café in a gray manner, and the boss in black didn't need the help of Xiao Siyan this time, he removed the hacker's special keyboard and mouse, picked it up and left.

"Tear the banner at the door to Lao Tzu!" The owner of the Internet café was furious and reprimanded the network manager: "Send someone again, go to them and get the Internet fee back for these few hours!" ”

(Two more are completed, and the number of words has been added!) ）
