Rule department scholar

Lin Xudong talked about the case unsurprisingly, "Huang Hongguo really has an accomplice. He is his ex-wife's younger brother. His body was carried away in a suitcase. We dug it up in a cemetery in the suburbs."

"I have already submitted your name, and the bonus will be issued in a few days."

Zhao Yi nodded.

As long as he is not used as a mobile lie detector, it doesn't matter if the bonus is not paid.

"However, I'm not looking for you for this." Lin Xudong continued, "I want to ask you for a favor. That's right. Recently, the police department's system has been attacked by hackers. The internal system is fine, but There is a problem with the general network and website."

"In the past two days, experts have been asked to do maintenance and security upgrades, but it's hard to say how safe it is. The above means to find a few trustworthy people, try to attack it, and fix it if you find any loopholes."

"I just thought of you, aren't you a hacker? So..."

When Lin Xudong said it, the general meaning was to ask Zhao Yi to try to use hackers to attack the police website and network to help check the quality of security.

They found several computer experts.

Zhao Yi is one of them.

The difference is that Zhao Yi was recommended by Lin Xudong, and there is competition within the police force. Zhao Yi's joining is tantamount to helping Lin Xudong.

Zhao Yi listened to the constant nodding, his expression did not change, and he felt a little uneasy. His title of "hacker" was obtained by cracking the fruit operating system. The cracking relied on his memory more than ten years ago, but the impression he gave was It's the top hacker.

Now admit that you are not a hacker?

Shameless!

Even if you hold on at this time, you must show that you are a 'top hacker'!

write a summary

Chapter 97 Come right back to me and explain clearly!

The first thing Zhao Yi did when he got home was to search for information related to hacking.

He really doesn't understand.

Programmers and hackers can't be said to be in two worlds, but they definitely don't have much connection.

Hackers are not necessarily powerful, they are only interested in intrusion methods, some rookies simply use some public hacking software, and there is nothing they can do if the software loses its effect.

Zhao Yi checked some introduction materials and got a little understanding of hackers' methods, but he is also sure that the information on the Internet is not very useful. If you want to break into the website of the police department, it is meaningless to study and imitate.

He tried it.

The external website of the Zhengyang police department has only been established for a year. The website of the government department is not easy to give direct criticism... Anyway, it is not very good.

Zhao Yi knew at a glance that the website was edited by using a web editor to directly draw the frame, and he must not have hired a professional website designer.

This kind of website is really terrible, even to update the news information, you need to modify the original code.

But also normal.

At present, most of the websites in China are like this. Many departments and units don't care about the website. The establishment of the website by the police is just to create a platform for distributing information, or it can be said to be a "face project".

website.

Yes, it is enough.

Zhao Yi turned on the command mode, pinged the website and got the IP address of the server.

This is a small loophole.

For security reasons, some websites will hide the IP address, and a normal ping will not return any data at all.

After getting the IP address, Zhao Yi didn't know what to do, so he simply started researching the website, checked it in source code mode, and discovered the file name of the root directory of the website.

“So easy?”

He was a little surprised that he got the file name of the website directory without any means at all.

What else did Lin Xudong say, 'I have found an expert to upgrade the safety performance'?

What kind of expert is this?

Not reliable!

Zhao Yi entered the website of the police department, added the suffixes of several files respectively, and immediately found the administrator link entrance.

Next...

I don't know what to do again!

The administrator's entrance is the door to invade the website, but it is obviously not an easy task to obtain the administrator's login ID and password. There are several software introduced on the Internet, and he tried them all, but they were all deceptive.

This is also normal.

Public hacking software is easy to use, and everyone can become a hacker.

Zhao Yi rested his chin and thought, "I really don't know much about hacking, but I can design hacking software? It shouldn't be complicated to design it for my own use..."

"What is needed now is to crack the administrator ID and password. The best way is to intercept information."

"As long as you design a program that intercepts routing information, it can intercept the information packets when it runs, and then analyze according to the information packets..."

Zhao Yi found a way.

He opened the programming software and began to think about the code, intercepting routing information, which sounds simple, but in fact, it is still a bit complicated. To be honest, it will involve a lot of knowledge.

But Zhao Yi is still very confident.

Working in a small company can really train a person, because a lot of work has to be done by himself, and he has a certain understanding of the underlying code, commands, software design and other aspects.

It is the first time to design monitoring software for routing.

Thinking of being able to monitor and intercept information, Zhao Yi suddenly found a passion for coding. The ability of hacking always gives people a cool feeling, and he also hopes to become a powerful hacker.

It's not for the purpose of invading anything, it's just very interesting.

……

Exploring in different fields is definitely a time-consuming task. Routing and intercepting software involves some physical layer codes and functions.

Zhao Yi searched a lot of information in the middle of writing the code, and then relied on "The Law of Cause and Effect" and "Contact Rate" to continuously improve the core framework. After writing the main code, he looked at the time and found that it was a bit late.

It's one o'clock!

He lay down on the bed and fell asleep.

At five o'clock the next morning, Zhao Yi opened his eyes and became more energetic. He immediately devoted himself to perfecting the code.

This software does not need to be used by others, it is enough to run the feedback data.

After spending an hour perfecting it, entering the fixed ip and finding that it could run, Zhao Yi stretched long, feeling a sense of accomplishment all over his body.

Start listening!

He didn't know if it would work, so he could only let the program run and try it out, come back at night to see the feedback data, and then think about what to do next.

Routing monitoring is also limited.

Its function can be imagined as that a camera is installed at the door of the house, and the camera can illuminate the keyhole. The owner of the house must use the key to open the door when going out or entering the door. Equipped with one, it can open the door directly.

It is too easy for the owner of the house to make protection. He knows that if there is a camera, it is enough to block the keyhole with his body.

In addition, he can change the fingerprint lock.

If he knows the location of the camera, he can stick something on the hole, or simply destroy it violently.

and many more.

The premise is that the owner of the house knows and pays attention to the protection of keys and door locks.

……

After Zhao Yi let the program run, he went to school by bike. Because he didn't get enough sleep, he slept for the whole class in Li Lisheng's English class.

Li Lisheng looked very helpless.

Every time Zhao Yi sleeps, he chooses English class. The key point is that he can’t say anything. Zhao Yi’s score is really high. It really doesn’t matter whether he listens to the class or not, but it’s a bit too much to sleep all the time.

As the director of the third year of high school, he also wants to save face!

Li Lisheng simply walked around beside Zhao Yi.

passing by.

Pass by again.

Passed by three times...

He stared at Zhao Yi, and everyone else could see it.

Lin Xiaoqing was sitting in front of Zhao Yi, and the teacher was always "passing by" and felt awkward, so she turned her head and patted Zhao Yi, "Wake up."

Zhao Yi opened his eyes in bewilderment, looked up and saw Li Lisheng who was "passing by again", and subconsciously asked, "Ms. Li, are you still in get out of class?"

Li Lisheng's face turned dark immediately.

"Forget it, just read when you wake up." Zhao Yi shook his head, took out a chemistry book, and started to chew.

Li Lisheng took a deep breath.

When he got back to the podium, he couldn't catch his breath. He raised his head and suddenly saw a dozing figure behind Zhao Yi.

he is……?

Li Lisheng pointed in Zhao Yi's direction, "That! That..."

"Me?" Zhao Yi was puzzled.

"No."

Li Lisheng simply walked over, walked past Zhao Yi's position, and slammed Wang Jian's table.

"Oh!"

"Sleep in class, and stand for punishment later! Also, copy the questions you just said ten times!"

Wang Jian raised his head in bewilderment.

He just couldn't help dozing off, why was he punished so badly?

between classes.

Lin Xiaoqing turned her head and asked Zhao Yi, "What's wrong with you today? You slept so hard in class."

Zhao Yi said, "I went to bed very late last night."

"What are you doing?"

"It's not because of you!"

Several people nearby looked over, their eyes full of gossip.

"what?"

Lin Xiaoqing's face flushed with embarrassment.

Zhao Yidao, "It's because of you. If it wasn't for you, how would your dad know me? If he doesn't know me, he wouldn't let me help. I was busy with your dad's business until one o'clock in the evening..."

"cut!"

"So it is."

"It's boring!"

"I thought there was something wrong!" The group of people turned their heads bored.

Lin Xiaoqing gave Zhao Yi a hard look, then turned her head with eyes full of disdain, "Hmph!"

everyday.

After returning home that night, Zhao Yi immediately went to the computer and checked the feedback information from the monitor. The information was stored in a file. After reading some of the content at the beginning, he knew he had succeeded.

Routing listeners are surprisingly effective!

Most of the file information is useless, but there are also some very direct information, such as someone's name, ID number, address, and links to some web pages, including several penguin numbers and passwords.

He tried to log in to one.

"my heart only has you?"

Zhao Yi shook his head and commented, "It's so stupid, such a boring screen name, a bad street, super boring..."

A new message is displayed in the lower right corner.

When Zhao Yi saw the profile picture, he knew it was Lin Xiaoqing. He opened it and saw a few words.
