Genius of the Rules-Style System

Zhao Yi thinks.

As a top hacker, you must have the highest level of network security awareness.

When he noticed that something seemed wrong, he immediately closed the Penguin account he logged in to, found the Penguin installation folder, and deleted the record folder of the Penguin account he had just logged in to.

besides.

In the routing monitoring feedback file, all penguin numbers and passwords are also deleted.

Done!

"So, I haven't done anything. Even if someone suspects it, there is no evidence."

"Start now, selective forgetting!"

Zhao Yi began to look at the monitoring feedback file carefully. There was a lot of messy content in the file, and most of it was garbled code that could not be deciphered. He could only read carefully line by line and excerpt the information that was 'suspected to be the ID password'.

After reading them all and looking at the dozens of ID and password data in the document, he did not rush to try to log in, but modified the source code of routing monitoring.

Must add something!

The content of the monitoring feedback file was too complex, and it was time-consuming to look at it one by one with the naked eye, and important information might be missed. He simply added a small output program to group the monitored content.

A web link is a group.

Various login IDs and passwords are set into a group, and feedback to the corresponding websites and software is also marked.

The remaining cluttered information and garbled codes are grouped together.

Firstly.

Zhao Yi debugged and ran it again. After finding that there was no problem, he opened the administrator page of the police website and logged in using the ID and password he had heard.

After trying more than ten times in a row, I finally jumped in and logged in.

Zhao Yi was really a little excited. After entering the management page, he saw that the layout, classification and fixed pictures were worse than the website he designed, and he couldn't help complaining in his heart.

Lin Xudong also said that "the above has allocated funds for network security", so why can't we just spend a little bit on website construction? Even if you only hire a professional website designer and artist, working on it for a few days can make the website quality take off qualitatively.

Of course.

Zhao Yi also somewhat understands that the information on the police website cannot be modified casually. Many news and information releases must be carefully considered and considered again, and may involve confidentiality, so they must be managed by internal people.

The rise of the Internet in China has only occurred in recent years. It is really difficult to find someone in the police department who is good at website design and maintenance.

Now that we've been invaded, what should we do?

Zhao Yi suddenly remembered that Lin Xudong had given him a piece of paper, which seemed to be information related to himself. When he got home, he put it under the computer without looking at it, and quickly took it out and glanced at it.

Name: Zhao Yi.

ID number: xxxxxxxxxxxxxxxxxx.

Recommender: Lin Xudong, Captain of the Criminal Investigation Section of Zhengyang Municipal Public Security Bureau.

Codename: Yiying.

"Yi Ying?"

"This code name is not bad!"

Zhao Yi thought about it for a moment and nodded with satisfaction, "I am like an eagle spreading its wings in the sky."

He knew what to do.

Find a picture of an eagle spreading its wings on the Internet and make it into a simple Flash animation. Write the two words "Yiying" on the top layer, hang it on the news picture on the homepage of the website, and set a password to modify the permissions.

Embed link.

Put a...music on the link?

Zhao Yi thought about it and searched for music. He found several songs and listened to several of them but they were not interesting. He listened to a powerful dance music and suddenly thought of the divine song from more than ten years later.

"Otherwise, just sing a few lines and forget it!"

“This is what makes it unique!”

He simply found a recording software and recorded a few lines of a cappella explosive dance music——

The flower in my heart, I want to take you home,

In that bar late at night, no matter whether it was true or false.

Please swing to your heart's content and forget about the person you love,

You are the most charming, you know?

…

Come to the left and draw a dragon with me

Draw a rainbow on your right (walk up)

Come to the left and paint a rainbow with me

Draw another dragon on your right (don’t stop)

…

Have fun singing!

Zhao Yi found that his voice was much better than it was more than ten years ago. It was a little childish, and when he sang it didn't sound like an old man, but it had a bit of youthfulness.

He sang a whole song!

I forgot some words, so I hummed along with the tone, and added the word "Yi Ying" by the way.

open the Web page.

Upload the recorded audio and add a picture of a late-night bar DJ.

OK!

That's all!

Zhao Yi closed the webpage happily and continued to write the paper.

paper.

Hurry up and finish writing! Hurry up!

…

at the same time.

Lin Xudong returned home full of confusion. Normally, he would have to work the night shift today, and he would have to sleep in the bureau. However, his wife was inexplicably angry. If she didn't go back and coax her, she would cause a scene, so she could only explain it to her colleagues. , go home and have a look first.

When he got home, he was greeted by a violent storm.

"Lin Xudong, you heartless person! Tell me! What is going on? Which beautiful lady are you chatting with!"

Lin Xudong retorted depressedly, "What are you talking about!"

"What? What else? I have evidence. Qingqing, show your dad the Penguin news. He still doesn't admit it!"

Lin Xudong went over and took a look. He was a little confused with his mouth open. He thought about it carefully and suddenly said, "I just said, why did the Penguin suddenly go offline? It must have been stolen!"

"Stolen? What a lame excuse. You logged in at your workplace, and someone could hack into your workplace and steal your account. Did he target you intentionally? And he happened to reply to my message right away? Think about it for yourself, is it possible? "

Zhao Hongjuan spoke very logically.

Lin Xudong thought it was impossible when he heard it, but that message was definitely not sent by him.

What an injustice!

What follows is a verbal battle between the two couples.

Women are unreasonable.

Originally, Zhao Hongjuan was worried about Lin Xudong. He was a man in his early forties, square and handsome, and he was the captain of the Criminal Investigation Division. He would definitely face a lot of temptations, and there might be some little girl, right. Something happened when he was secretly in love.

She also took this opportunity to vent.

Lin Xudong explained at first, but in the end he could only bow his head and give in. He was so depressed that he just listened.

That's how men are.

It's like a joke on the Internet said, "I wanted to write an apology letter to my wife, but after looking at the white paper for a long time, I could only write the words 'I was wrong' because I didn't know what I did wrong."

Lin Xudong didn't even know what to do.

the phone is ringing.

Zhao Hongjuan still knew the importance and did not disturb Lin Xudong to answer the phone.

Lin Xudong picked up the phone and heard a strange tune coming from the other side, "Come on, draw a dragon with me on the left, and draw a rainbow on your right..."

"what!"

"Xiao Zhang?"

Lin Xudong gave a strong reminder before the other person finally spoke, his voice a little excited, "Captain Lin, the police website has been hacked. It's the Yiying you recommended. It's amazing."

"Yi Ying?"

"right!"

Xiao Zhang gloated and said, "Team Li also said they found a few computer geniuses, but what was the result? None of them worked. Team Lin, you found one who can surpass several of them!"

"Also, this Yiying is really interesting. He sings quite nicely. Do you know what song this is? I searched online for a long time and couldn't find it..."

Lin Xudong put down his phone in a happy mood.

There is also competition among various police departments. Competition in solving crimes and investigation is on the one hand, but there is also competition in other tasks. The police departments have always attached great importance to aspects such as websites and network information, but it is almost impossible for the police to show professionalism. Talents.

Nowadays, when it comes to testing the security of websites, how well they can find "trustworthy people" can be regarded as a kind of direct competition. The higher-ups will definitely care about who has breached the website.

When the time comes, when asked, he will mention, "This person was recommended by Captain Lin."

This is also the skill.

Lin Xudong's good mood lasted for more than ten seconds, and then he had to continue to be baptized by the violent storm.

…

The manager of the Zhengyang City Police website is Li Jiandong from the logistics department. He has a bachelor's degree in computer science. After graduation, he did not go out to find a job. Instead, he enrolled in the public security department after attending the police academy.

When building the police website, we directly approached the logistics department. Li Jiandong was directly responsible for managing and maintaining the website.

Some time ago, the police network was attacked by hackers.

In order to improve the security of the network, they hired specialized computer experts to try to attack the website to find vulnerabilities.

This is a test of website security and a test of Li Jiandong’s work.

Li Jiandong didn't pay special attention.

He is not a professional network security person, but because he is responsible for managing and maintaining the website, he also knows some hacker methods. The website was attacked some time ago, but the server was paralyzed for a period of time.

This kind of brute force attack is related to server performance. There is no way to fight against it. The only way is to upgrade the performance of the hardware. But even if it is violently attacked, it will not have much impact.

At best, restart the server.

Now is also an opportunity to prove that the website is safe and cannot be broken by computer experts.

This evening.

Li Jiandong checked the website as usual before going to bed, and immediately felt no sleepiness at all. The picture of the leader's inspection on the main page had been tampered with, and a flash animation of a flying eagle was placed.

"Yi Ying?"

Li Jiandong clicked on the picture and found the link.

A weird a cappella song was played, and Li Jiandong became more and more irritated the more he listened to it. If the web page was tampered with, it meant that it had been breached. Doesn't it directly mean that he was mocking his work?

Li Jiandong quickly logged in to the management page and wanted to modify the webpage back. However, after clicking in, he found that he could not modify it at all.

Want permission?

Do you want to enter a password?

Li Jiandong was depressed to find that he could not modify it for the time being. He had to go to the bureau's computer to find the source code before he could directly delete and modify it.

According to the normal process, after someone breaks into a website, they will ask the other party to submit a security vulnerability. After the vulnerability is patched, the security will naturally be improved.

Li Jiandong didn't want to do this.

If the other party reports a security vulnerability, the superiors will definitely know about it, which is equivalent to putting an 'X' on his work, and both he and the logistics department will be embarrassed.

Li Jiandong thought about it and decided not to submit it. He would go to the bureau early tomorrow and modify the source code on the computer.

He also knew the problem--

The other party must have entered the management page to make so many changes. It was like designing a web page, with links embedded in the animation.

So...change your password!

As long as you change a complex management password, the other party will not be able to easily crack it.
