Rule system

Zhao Yi thinks.

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

When he found something wrong, he immediately shut down the landing Penguin, found the installation folder of Penguin by the way, and deleted the record folder of the Penguin just before landing.

and also.

The penguin number and password are also deleted from the file of the routing monitoring feedback.

Get it done!

"So, I haven't done anything, even if someone suspects it, I can't find evidence."

"Now, selective forgetting!"

Zhao Yi began to look carefully at the files for monitoring feedback. There were a lot of messy content in the files, and most of them were garbled codes that could not be deciphered. He could only look carefully line by line and extract the information of the'suspected id password'.

After reading all of them, looking at the more than a dozen id and password data in the document, he was not in a hurry to try to log in, but modified the source code of the routing monitor.

Must add something!

The content of the monitoring feedback file is too complicated, it takes time to look at it one by one with the naked eye, and you may miss important information. He simply added an output applet to group the monitored content.

Web links are a group.

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

The remaining messy information and messy codes are grouped together.

Firstly.

Zhao Yi debugged and ran it again. After finding that there was nothing wrong, he opened the administrator page of the police website and used the monitored ID and password to log in to see.

After trying a dozen times in a row, I finally jumped in and logged in.

Zhao Yi was really a little excited. After entering the management page, he couldn't help but complain about the worse layout, classification, and fixed pictures than the website he designed.

Lin Xudong also said that "the funds have been allocated for network security", can't I use that little bit on website construction?Even if you only hire a professional website design and art artist, you can make the quality of the website take off for a few days.

Of course.

Zhao Yi can also understand a little bit that the information on the police website cannot be arbitrarily modified. Many news and information releases must be carefully considered and then considered. There may also be confidentiality involved, which must be managed by insiders.

The domestic Internet has only emerged in recent years. It is too difficult to find someone who is good at website design and maintenance in the police department.

Now it’s invaded, what should I do?

Zhao Yi suddenly thought that Lin Xudong had given a piece of paper, which seemed to be related to himself. When he went home, he pressed it under the computer without reading it, and quickly took it out and glanced at it.

Name: Zhao Yi.

ID number: xxxxxxxxxxxxxxxxxx.

Referrer: Lin Xudong, Captain of the Criminal Investigation Division of Zhengyang Public Security Bureau.

Code name: Yiying.

"Yi Ying?"

"This code name is not bad!"

Zhao Yi pondered for a while and nodded in 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 from the Internet and make a simple Flash animation. Write the words "Yiying" on the top layer, hang it on the big news picture on the homepage of the website, and set a password for modification permissions by the way.

Embed link.

Put a...music on the link?

Zhao Yi thought about searching for music. He found several songs and listened to several capitals. He was listening to a great dance music, and suddenly he thought of a divine comedy ten years later.

"Or, just sing a few words!"

"This is unique!"

He simply found a recording software and recorded a few a cappella dance music--

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

In that late night bar, it doesn't matter whether it is true or not.

Please swing as much as you want, forget about him,

You are the most charming Karma, do 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 draw a rainbow with me

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

...

Sing hi!

Zhao Yi found that his voice was much better than that of more than ten years later, with a little immature meaning. He did not sing like an old man, but with a little youthfulness.

He sang a whole song!

Some words were forgotten, so he hummed along the tone and added the word'Yiying' incidentally.

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 web page happily, and continued to write his thesis.

paper.

Finish writing quickly, finish quickly!

...

at the same time.

Lin Xudong returned home in confusion. Normally, he was on night shift today. He would definitely have to sleep in the bureau, but his wife was inexplicably angry. If he didn't go back to coax the sky, he could only explain to his colleagues. , First go home and have a look.

When he got home, he ushered in a violent storm.

"Lin Xudong, you have no conscience! Tell me! What is going on? Which big beauty is talking to!"

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

"What? What else? I have evidence. Qingqing, show your dad the news about Penguins. He doesn't admit what he said!"

Lin Xudong took a look in the past, his mouth was a little stunned, he thought about it carefully, and immediately said, "I said, why did the Penguin suddenly go offline? It must be stolen!"

"Stolen? What bad excuse, you logged in at your unit, and someone could hack your unit to steal your account. Did he deliberately target you? And he happened to give me a message back right away? Think about it yourself, is it possible? "

Zhao Hongjuan is very organized.

Lin Xudong thought it was impossible when he heard it, but he certainly didn't send the news.

Wrong!

The next step is the battle between the couple.

Women are unreasonable.

Originally, Zhao Hongjuan was not at ease with Lin Xudong. He was a man in his early forties, with a square appearance and a little handsome, and a captain of the Criminal Investigation Department. He would definitely face a lot of temptations. Maybe there would be a little girl, yes. Something happened when he was secretly in love.

She also took this opportunity to vent.

Lin Xudong explained at the beginning, but in the end he could only bow his head to admit counsel, and just listened depressed.

Men are like this.

It's like a comment on the Internet saying, "I want to write a letter of apology to my wife, but after looking at the blank paper for a long time, I can only write the three words'I am wrong' because I don't know what I did wrong."

Lin Xudong didn't 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 from the opposite 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 vigorous reminder, and the other side finally spoke, and the voice seemed a little excited, "Team Lin, the police website has been hacked, and that is the Yiying you recommended. It's amazing."

"Yi Ying?"

"Correct!"

Xiao Zhang said gleefully, "Team Li also said that they found a few computer geniuses. What happened? It didn't work. You found one, Team Lin, and several of them were on top!"

"Also, this Yiying is really interesting. He sings very well. Do you know what this song is? I haven't found it after searching online for a long time..."

Lin Xudong put down the phone in a good mood.

There is also competition among various police departments. The competition in solving crimes and investigating is one aspect, and there is competition in other work. The website and network information have always been attached great importance to, but it is almost impossible for police to be professional. Talents.

In the current work of inspecting website security, the extent to which the "trusted person" can be found is a kind of direct competition. The above will definitely care about who broke the website.

When you ask, you will mention, "This person is recommended by Captain Lin."

This is also a skill.

Lin Xudong's good mood lasted for more than ten seconds, and he had to continue to accept the baptism of the storm.

...

The Zhengyang police website is managed by 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, but entered the police department after enrolling in the police school.

When building the police website, I found the logistics department directly, and Li Jiandong was directly responsible for the management and maintenance of the website.

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

The above deliberately improved the security of the network, and I found a special computer expert, and tried 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 particularly care.

He is not a professional network security personnel, but because he is responsible for the management and maintenance of the website, he also understands some hacking methods. The website was attacked some time ago, and the server was paralyzed for a while.

This kind of brute force attack is related to server performance, and there is no way to fight it. You can only upgrade the performance of the hardware, but even if it is brute force attack, it will not cause much impact.

At most, restart the server.

Now is also an opportunity to prove it, let the above know that the website is safe, and it is impossible for a computer expert to break it.

This evening.

Before going to bed, Li Jiandong checked the website regularly, and he was completely relieved. The picture inspected by the leader of the main page was tampered with, and a flash animation of an eagle flying was displayed.

"Yi Ying?"

Li Jiandong clicked on the picture and found the link.

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

Li Jiandong hurriedly logged into the management page and wanted to modify the web page back. After clicking on it, he found that he couldn't modify it at all.

Want permissions?

Want to enter a password?

Li Jiandong was depressed and found that he couldn't modify it temporarily. He had to find the source code on the computer in the bureau before he could directly delete and modify it.

According to the normal process, after someone breaks the website, they will ask the other party to submit security loopholes. After the loopholes are patched, the security will naturally improve.

Li Jiandong didn't want to do that.

If you ask the other party to report a security breach, the above will definitely know it, which is equivalent to drawing an'X' on his work, and he and the logistics department will be ashamed.

Li Jiandong thought about it and decided not to submit it, and went to the bureau early tomorrow morning to 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's like designing a webpage, with links embedded in the animation.

So... change the password!

As long as you change a complicated management password, the other party cannot easily crack it.
