Genius of the Rules-Style System

The large news picture on the Zhengyang police website has a flash animation of a flying eagle, and when you click on it, there is a DJ singing a cappella and a powerful dance music.

This matter was known to many people.

People outside know less about it. The police website has not been established for a long time. It is only used to publish some information and does not provide any convenient services. Very few people will click on it to take a look.

Everyone who works in the police department, from the department leaders to the cleaning ladies who clean the stairs, all know this.

There was a lot of talk in the morning, and most just laughed about it.

The website was undergoing a security upgrade. It was not a secret, but the logistics department did not announce it on the website. They were more interested in the a cappella DJ.

Although it sounds weird without a soundtrack, the tone and lyrics are very interesting.

Many people also know the name of ‘Yi Ying’.

"Who is this Yi Ying? Captain Lin recommended him. He is really powerful. He broke into the website in one day."

"The people in the logistics office don't know anything about websites or security. If you ask me, these new things, technological things, need to be managed by specialized people. If this Yiying is recruited, they will definitely be let go. Greatly improve network security, at least I am not afraid that the Penguin will be stolen."

"Hahaha, don't you know? Captain Lin's Penguin may have been stolen yesterday, but he still logged in from the computer in the office."

"Now that hackers have infiltrated our department, the people who rely on logistics have no security at all."

The logistics people will definitely not be happy when they hear this.

Li Jiandong arrived earlier than anyone else. He entered the office at around six o'clock, turned on his computer, found the source code, and called the contents of the database to overwrite the modified pictures and links. Due to the impact of network speed and erroneous operations, the website was paralyzed for more than ten minutes.

Of course, it doesn't matter.

No one will be idle to check the website after six o'clock.

What Li Jiandong didn't realize was that all his operations to the server needed to go through a device called a "router," and the router used by the police department had been monitored remotely 24 hours a day.

morning.

Logistics department leader Zhou Hongwen found Li Jiandong and talked about the website being hacked yesterday.

Li Jiandong's answer was this, "I know how the other party broke into the website. I can just fix the loopholes directly. There is no need to report it to the superiors and let the other party submit the loopholes, right?"

Zhou Hongwen makes sense when he thinks about it.

The police department's website is managed by the logistics department. Knowing that the loopholes can be fixed directly, there is no need for the other party to submit the record. The record of "vulnerabilities reported by outsiders" is also a small stain on the work of the logistics department.

More importantly...

'Yi Ying' was recommended by the Criminal Investigation Department, not the logistics department. The above means that all departments can recommend people, but a group of investigators from the Criminal Investigation Department, the recommended person actually broke into the website, and the logistics department The person you recommended has done nothing?

This is a slap in the face!

Zhou Hongwen decided to trust Li Jiandong and did not report according to the established procedures.

Lin Xudong and the Criminal Investigation Department were unhappy, but there was nothing they could do about it being suppressed by the logistics department.

noon.

Lin Xudong called Zhao Yi and spoke apologetically about what happened in the morning, "You succeeded yesterday, but were suppressed by logistics. The things inside are a bit complicated, so I won't go into details with you."

"Anyway, I'm really sorry. Let's do this. I'll personally reward you with a thousand yuan."

Zhao Yi was a little surprised when he heard this.

Originally he thought it was over.

He built a routing monitoring software, broke into the police department's website, submitted a question according to the process, reminded the police to hide the management website entrance, and upgraded the security and encryption of the routing, and his work was completed.

He didn't care at all about how much money he could get from this job.

Thousands of dollars are nothing, it's just an hour's leisure part-time job. Even if it doesn't cost a penny, it can be regarded as helping the police department and improving network security.

Sounds...a bit great!

Zhao Yi didn't plan to continue doing anything. After all, he was not an insider of the police, so there was no need to spend too much time and energy on the security of the police website.

That's not great, that's sick.

Hearing Lin Xudong's explanation, Zhao Yi was secretly unhappy. Even if he didn't care about the bonus, he couldn't be suppressed like this, right?

"No, Uncle Lin." Zhao Yi refused and asked, "Do you still need my help? How about I go back today and post a picture on your website?"

"You can still go in?" Lin Xudong was a little surprised.

Zhao Yi asked, "Why not? Do you know how I got in?"

"I am not sure."

Lin Xudong didn't understand the technical issues of the network. He just knew that the logistics had suppressed the matter, which seemed to have found a loophole. He also felt very depressed. When he heard Zhao Yi said that he could still get in, he suddenly said with some expectation, "If it doesn't delay your When the time comes, just try again and make it bigger, it doesn’t matter, don’t worry, you, Uncle Lin, and I are here!”

"I have already reported your name. The police all know that 'Yi Ying' is one of their own."

"When the bonus is paid, I will personally subsidize you more..." Lin Xudong gritted his teeth and said a number, "Two thousand!"

"Thanks in advance."

Zhao Yi smiled and put down the phone.

Lin Xiaoqing was lying on the table, staring at him with blinking eyes, "What on earth did my dad ask you to help with?"

Zhao Yi looked around, put his head next to his little ears, and whispered slowly, "Secret!"

Lin Xiaoqing pricked up her ears and almost burst into anger when she heard the word 'secret'. She sat up and pouted, "You didn't even tell me, why did you come here so mysteriously?"

Zhao Yi said with a smile, "If you have fragrance, I will smell it!"

"What did you say? Shameless!"

Lin Xiaoqing blushed when she heard this, and quickly turned her head away. After a while, she turned back, and she hummed softly, but she still couldn't help being curious, "What on earth is going on? Tell me."

Zhao Yizheng was immersed in the joy of ‘Learning Coin + 3’. When he heard Lin Xiaoqing’s question, he felt that he should continue to work harder.

One breath!

Accumulate learning coins!

He leaned forward and pointed at his cheek and said with a smile, "In this way, you...hehe, I'll just say it!"

Lin Xiaoqing took a deep breath, stood up suddenly, and slapped the table.

"Bang!"

The whole class looked over.

She stared straight at Zhao Yi, and kept rubbing her wrists, as if she wanted to hit someone, "Should I tell you or not?"

Zhao Yi knew that Lin Xiaoqing was just trying to scare people, and every time he put on a violent posture, he actually didn't do anything at all, but he still pretended to be scared, and kept waving his hands and saying, "Woman, spare your life! Don't, don't, don't , Haha, I said! I said!”

Lin Xiaoqing sat down with satisfaction.

Zhao Yidao, "Actually, it's not a secret. Some time ago, Zheng Yang's police website was hacked..." He said briefly.

Zhao Linlin also stretched her head over to gossip.

This kind of thing is really interesting for little girls in high school. When they heard Zhao Yi say ‘continue to invade’, they started chattering about how to make modifications that would be more interesting.

"You just posted a picture of an eagle? How boring!"

"We should change it to a spoof picture!"

"Change the background to No. 13 Middle School, and then the police website will become an education website..."

Zhao Yi ignored it.

This is just what a little girl said casually.

That was the Zhengyang City Police website. No matter how bad it was, it was still a national department website. Even if it was a spoof, there must be a limit. It only needed to leave traces to prove a successful intrusion.

After each suggestion was directly rejected by Zhao Yi, they started thinking in other aspects.

Zhao Linlin is indeed a little witch.

Each suggestion she made made Zhao Yidu's eyes light up and he decided to adopt one of them.

…

It's about nine o'clock in the evening.

Zhao Yi arrived home on time and rushed to the computer, opened the management page of the police website, logged in and found that he could not enter.

"Changed your password?"

He turned on the monitoring software.

The monitoring software was always on, and there was a lot more content in one day. Because he knew that the website would be restored in the morning, he found the content he wanted without having to sift carefully -

A login ID and several new passwords.

"Has it been changed several times?"

Zhao Yi tried the passwords one by one and quickly logged in again. He continued what he did yesterday, replacing the big news picture with an eagle animation, and then put a link directly to the recorded DJ song.

What happens next is different.

He raised the permission to modify pictures and links to the highest level, and they can only be modified from the source code library.

If the other party does not know the password, he has two options if he wants to modify it: either perform a brute force crack, which is technically difficult; or directly modify the underlying code and re-upload and load the website.

The second operation is different from the previous day.

The day before, you only need to use the source code to directly overwrite the contents of the database, and you can remove the Flash animation and links of the eagle. However, if you upgrade to the highest level of modification, calling the database cannot overwrite it, so external access must be temporarily closed. After modifying the source code and uploading it to the server, restart the server.

Due to network operator service delays, the website will be down for at least a few hours.

Of course.

Zhao Yi couldn't keep the police website down for several hours, so he still left a backdoor for recovery.

If someone enters the management page, they can see a hidden high school function question next to the eagle animation.

This function question is very brain-burning, and ordinary students cannot solve it at all. Even with Sun Liang's level of mathematical ability, it would take a long time to think and meditate.

There is a note below the math problem--

[The answer to the question multiplied by pi is the final digital code. (Special reminder: if the password exceeds ten digits, there is no point in guessing the answer/smiley face)]

After Zhao Yi completed the operation, he took a screenshot and sent it to Lin Xiaoqing, asking Lin Xiaoqing to help forward it to Lin Xudong to ask if it was too much to do this.

Lin Xudong burst out laughing when he saw the screenshot.

Math question?

What a creative idea!

He immediately picked up his phone and replied the message, "Zhao Yi, good job. No problem, don't worry!"

opposite.

Zhao Yi glanced at the messages on his phone. After feeling relieved, he looked at the computer screen. There was a message from a stranger on Penguin.

The security message from the 'Computer Technology Exchange Group' was Zhou Ming: "Zhao Yi, do you know about last week's hacker attack? Overseas hackers launched a wave of violent intrusions against peripheral websites of our public services."

"We are preparing to organize a counterattack, and the time is set to be in the middle of next month. Are you interested in participating?"

"If you are interested, please join the group: xxxxxxxx."
