Bit Mania [Hacking]

Zheng Xiu, what is he,

Zixin looked at the sentence sent by Xingchu, completely confused, and had no time to think about it. The strange silence after the other party's sentence gave him a warning sign, and he quickly exited the system of the air force base. When he finally left, he looked back. At a glance, all traces of his intrusion have been completely removed by Xingchu.

There was an ominous premonition in his heart, Zixin sat in front of the computer frowning, and finally sent a message to Zheng Xiu.

Octo, Qi Xingchu said that he is not the spreader of the virus, do you... know who it is, Israel: Who do you think it is?

Octo: No idea...he mentioned you.

Israel: Huh?

Octo: ...I don't know.

Looking at the sentence sent by the other party, Zheng Xiu frowned imperceptibly, and then quickly stretched out, leaning on the computer chair with ease, with one hand supporting his head, and the other hand slowly Beat the beat.

"one two three four five six seven."

When I counted to seven, the computer screen in front of me froze indiscernibly, and the blinking cursor froze for a moment, and then quickly returned to normal. If you don't pay attention wholeheartedly, such a change is almost hard to notice At most, I just thought the machine was stuck for a while, but after that, the chassis started to make a louder buzzing sound than before.

"It took seven seconds... let's give it 75 points." Zheng Xiu smiled inexplicably.

He knew that although the computer on the table was still in front of him, it was no longer his own. At this moment, it was like a pile of scrap metal to him.Someone stole the keys and was looking through his computer.

Smiling, stood up and walked into the kitchen, put water in the pot, put it on the gas, lit the fire and started it, after a while, opened a pack of instant noodles and threw it in, cracked an egg, and turned off the gas when it was almost cooked , walked slowly into the living room with instant noodles, put the noodles on the coffee table, lay down on the sofa, touched from the sofa cushion pressed under him, and a comic book appeared in his hand so miraculously .

"Is it really good to eat instant noodles when you grow up? Will it make you grow taller...although you are already very handsome..."

While Zheng Xiu was muttering, he just left the computer that was turned on, and started eating and reading on his own.

Two hours later, someone yawned, sat up lazily from the sofa, brushed his hair twice, and returned to the computer again. At this time, the computer had resumed its original control authority.

Israel: Hi.

Octo: Sorry!

Octo: I... I took control of your computer just now, I thought you were related to this virus... I didn't expect that you really don't have any hacking skills...

He didn't expect the other party to admit it so actively. Israel: ...Is that so.

Octo: I'm really, really sorry!I shouldn't doubt your...

Israel: It’s okay, as long as you believe me from now on, it’s the same, I really like you.

Octo: Uh... well, thank you... I really couldn't do it for a while... I promise I didn't check any of your privacy, and I didn't destroy anything... In order to compensate you, I help you put the computer The defense system has been optimized, in the future you will not be so easily... invaded...

Israel: You are so kind to me^_^

Octo: It should be...

Israel: It seems that you are not in a good mood, so let me take you to a place.

Octo: Where?

Israel: window to the world.

"...What an idiot." Zixin couldn't help scolding himself. He was so impulsive. Qi Xingchu only mentioned Zheng Xiu, so he suspected him. When he thought that Zheng Xiu seemed to know something about the virus, he immediately Recklessly hacked into his computer, turned it inside out.

If it's someone he doesn't know, like those guys in the chat room, Zixin can throw viruses and wreak havoc without hesitation, but Zheng Xiu has helped him so much, he can clearly feel the kindness of this person towards him, It's unreasonable to do this to him.

Zheng Xiu's computer is completely an ordinary civilian computer, and there is no clue in it that he has superb hacking skills. You must know that people who are proficient in computer technology, even if they hide it deliberately, some habits are still difficult to completely correct. There will always be some information leaked more or less in the computer, but these can not be found in Zheng Xiu's computer, unless Zheng Xiu's attainments are high enough to hide the truth under his nose, it can only prove that—— This person is really not computer-savvy.

Thinking back now, Xingchu and Zheng Xiu should know each other, so Xingchu only mentioned this person to him in the air force base. If Zheng Xiu is not the spreader of the virus, combined with his excellent mathematics Talent, the kind of familiar auxiliary force shown in many cooperations with him, and Zheng's considerate care for himself, the remaining possibility is——

Zheng Xiu and Xingchu should be friends rather than enemies, and they were even entrusted by Xingchu to accompany him... Oh my god, I suspect him...

While thinking wildly, Zixin found the target server according to the IP address given by Zheng Xiu.It is an open server, and everyone can access it through the client side of the network, and this server provides a detailed hypertext service, and Zixin can even see the server's owner on it. announcement.

"Welcome to this website, everyone."

His eyes widened in surprise. Unlike in the past when he was thinking about computers alone, he has recently mixed with Mr. Song and a group of seniors who are elite young students in the computer field. His knowledge has long been different from the past. And what appeared in front of him now was a character that only existed in theory in the past.

Israel: It’s unbelievable. The World Wide Web Hypertext Protocol was established. The place where we are now is the first officially launched and open website in human history.He will be forever recorded in history.Today, let us witness history together.

Perhaps in the eyes of today's people, this is just an extremely common element of life. To browse a certain webpage is just a matter of clicking the little finger on the mouse. It is a gathering place for people, and the connection between computers is only for the sharing of information resources, but there is no service function for civilians.

However, from the moment the website appeared, everything changed.

Zixin browsed this website carefully. Its job is not to serve any organization or group, but to focus on how to build a website, manage a website, database, etc. technology, that is to say, the world's first website in front of you , is a textbook that teaches others how to build their own website!

Its establishment is like the first telephone created by human beings, but the manufacturer did not apply for a patent or hold this technology as a treasure, but advertised it to the world, intending to make it available to everyone. Use the phone.

"In this way, my phone can connect to all parts of the world." Said the inventor.

"Global information sharing..." Zixin murmured, "What a huge project this is."

Octo: Will his ideal come true?

Israel: Yes, it will happen in the near future.

Octo: Soon?

Israel: Yes.The human desire to communicate is as strong as it is realized.

Lee: You are so right.

Octo: Are you...?

Lee: The founder of this website, I am very glad that the two of you are here today.

Israel: You’re welcome. You must be very busy on the first day of launch, right?

Lee: Yeah, after all, it’s the first time I’m doing this kind of thing. Many places are not well thought out, and the website has a lot of loopholes. I have to keep patching it to prevent hackers from taking advantage of it... Well, I still have to work, maybe I can't greet you in a thoughtful manner for the time being. If you are willing to give me credit, you can register with me. There is a BBS (forum) on the website. There are already many people there. You can communicate and exchange, and maybe you can find something you are interested in. I wish you all have fun.

After bidding farewell to Lee, the founder of the website, the two found the BBS, registered respectively and logged in. Sure enough, it was very lively, with several new posts almost every few minutes, and some hot topics that everyone was interested in had accumulated on the Internet. Hundreds of comments, most of which are discussions created by industry insiders on this website.

Among them, a post named "Bang Bang Lao Li" was always at the top, and the bright red title was enhanced. The two clicked in and saw that a group of well-meaning people put forward personal suggestions for improving the website. Xin read one by one, some are about database expansion applications, registry shortcut keys, link cache, etc., and even some website decoration design stuff, I can’t see that there are guys with good art talents in this group of people It exists, and Lee seems to be willing to listen to their suggestions, and hangs a Flash animation made by one person on the homepage. Unfortunately, the Flash resolution is too high and has not been compressed. The traffic demand of the website prevented the page from being refreshed, which immediately attracted scolding.

Seeing that so many people were more or less working hard, it was not a problem for Zixin to stare at the side, so he discussed with Zheng Xiu, thinking that Lee seemed to be too busy defending against hackers before, so he targeted the website. We edited several patches for the bug, hoping to reduce his workload.

After patching, the two returned to the post. They were away for more than a quarter of an hour, and the post was followed dozens of floors. It was really hot. Zixin found the place he saw before and continued to scroll down. Suddenly, a particularly lively The post caught his attention.

[#184] Afier: Our website deploys an Nginx server. In order to prevent hackers from hanging horses, I think we can apply an anti-PHP patch to it in the Javascript environment, so as to solve the problem that 0-day vulnerabilities may be invaded.

[#185] Season: Wow...what a great idea.

[#186] Afier: As long as this patch is applied, we don't have to worry about the security of our website!

[#187]Mild: Great, the professor will give you the detailed code!

[#188] Afier: The code is here.

[#189]Season: ...A master!

[#190] Mild: Admiration, admiration!

[#191] Afier: It’s just some pediatrics, nothing to brag about, as long as you study persistently, you will be like me in the future...

[#192]Octo: That...Nginx has a problem with parsing the PHP script file path. If you make a .zip file containing a PHP Trojan and insert it into the head area of ​​the webpage, it will be easy to install the Trojan.

[#193] Mild: ...

[#194] Pie: Do you want to chat with beautiful girls? Come to the crazy love chat room, room number 13xxx...

[#195] Season: ...

[#196]Mild: ...Yes, is that so, Professor?

[#197] Afier: Uh...cough!This is ridiculous, my patch will be fine!Your file... Ah, yes, your file will not pass the parsing level of the script environment at all, it will block all malicious programs!

[#198] Octo: Heh, I know that, but what if the uploaded file is harmless?

[#199] Afier: What do you mean? !

[#200]Octo: First upload a small file containing PHP script to the website. It is well concealed and cannot be executed on the server itself, so it will not cause any harm to the server, so accordingly it will not Is blocked, it is only "vanguard", used to change the PHP environment implicitly.

[#201] Afier: Well, then...?

[#202]Octo: After the bridge is built, our large troops can move in. At this time, just add a /t.php statement after the normal URL, and Nginx will upload any files uploaded next. Including the real Trojan horse, all run as PHP - webshell is also in the bag.

After the post was posted, the entire building fell into complete silence, and an indescribable atmosphere spread, and everyone was silent. Some people might still be in the fog, but many more people were already covered in cold sweat .If a hacker really uses this two-stage method to sneak in... no one can stop it, no, no one thought that they would be attacked by this kind of attack, so they never thought of being able to stop it at all. The defense in this respect is simply It's... a blank space.

——This will be a nightmare. Once the Tower of Babel, which Lee built with great painstaking efforts, is attacked by such an attack, it will be destroyed overnight and become the biggest achievement in the eyes of some hackers, and a joke.

In the silent post, some people subconsciously pressed their fingers to refresh. After a long time, a new reply appeared in everyone's eyes.

[#203] Viky: Liar!

Audience:? !

[#204] Viky: What kind of bullshit love chat room, there is not a single girl, it's all a bunch of gay guys pretending to be women in it...

Viky has been banned by the administrator from posting.
