Rule system

The big news picture of Zhengyang police website was hung with a flash animation of an eagle flying, and it was still a cappella DJ's blast dance.

This matter is 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. Few people will click in to see it.

People who work in the police department, the leaders of the department, and the cleaners who clean the stairs all know.

Many people were talking in the morning, and most people just smiled about it.

The website is undergoing security upgrades. It is not a special secret, but the logistics department has not published it on the website. They are more interested in the a cappella dj.

Although the lack of a soundtrack sounds weird, the accent and lyrics are very interesting.

Many people also know the name of'Yi Ying'.

"Who is this Yiying? Captain Lin recommended it. It's really amazing. It broke the website in one day."

"The group of people in the logistics department don't know any website or security at all. If you want me to say, these new things, technological things, they need to find special people, like this Yiying. 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. He still logged in from the office computer."

"Now that hackers have infiltrated our department, the group of people who are counting on logistics has no security at all."

The logistician must have been unhappy.

Li Jiandong came earlier than the others. He entered the office at 6 o'clock and turned on the computer to find the source code, and called the contents of the database to overwrite the modified pictures and links. The website was paralyzed for more than ten minutes due to the influence of internet speed and misoperation.

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 had to pass through a device called a'router' to pass to the server, and the router used by the police department had been monitored remotely for 24 hours.

morning.

Zhou Hongwen, the leader of the logistics department, approached Li Jiandong and talked about the website hack yesterday.

Li Jiandong’s answer is like this, "I know how the other party broke the website, just fill in the loopholes directly, there is no need to report to the above and let the other party submit loopholes?"

Zhou Hongwen makes sense to think about it.

The police department’s website is managed by the Logistics Department. Knowing that loopholes can be directly repaired, there is no need to ask the other party to submit them. The record of “vulnerabilities reported by outsiders” is also a small stain on the work of the logistics department.

More importantly...

'Yi Ying' is a person recommended by the Criminal Investigation Department, not by the logistics department. The above means that all departments can recommend people, but a group of detectives in the Criminal Investigation Department, the recommended person actually broke the website, and the logistics department The recommended person didn't even do anything?

That's it!

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

Lin Xudong and the Criminal Investigation Division were upset, but there was nothing to do when things were suppressed by the logistics department.

noon.

Lin Xudong called Zhao Yi and talked about the morning's affairs apologetically, "You succeeded yesterday, but you were suppressed by the logistics. The things inside are a bit complicated, so I won't talk to you in detail."

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

Zhao Yi was a little surprised.

At first he thought it was over.

I made a routing monitoring software, broke the website of the police department, 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 really care about how much money he could get for this job.

Thousands of dollars are nothing but an hour of leisure and part-time work. Even if you don't have a penny, it can be regarded as helping the police department and improving network security.

Sounds... kind of great!

Zhao Yi did not intend to continue doing anything. After all, he is not an insider of the police, and there is no need to spend too much time and energy on the security of the police website.

It's not great, it'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 asked after refusing, "Will I still use my help? Or should I go back today and go to your website to make a picture?"

"Can you 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 network technology issues. He just knew that logistics was holding down things, which meant that a loophole had been found. He was also very depressed. Hearing Zhao Yi said that he could still go in, he said with some expectation, “If it doesn’t delay you Time, you can try again, make it bigger, it’s okay, don’t worry, I have you, Uncle Lin!"

"I have reported your name. The police knows that Yi Ying is his own."

"At that time, the bonus will be issued, and I will personally subsidize you more..." Lin Xudong gritted his teeth and said a number, "Two thousand!"

"Thank you in advance."

Zhao Yi smiled and put down the phone.

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

Zhao Yi glanced left and right, put his head close to his little ear, and whispered slowly, "Secret!"

Lin Xiaoqing raised her ears and almost exploded when she heard the word'secret', she sat up and pouted, "Don't tell me, why come here to do it mysteriously."

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

"What are you talking about? Shameless!"

Lin Xiaoqing's face blushed, she turned her head quickly, turned her head after a while, and still couldn't restrain her curiosity, "What the hell is it, talk about it."

Zhao Yizheng was immersed in the joy of'learning coins +3', and heard Lin Xiaoqing's questioning that he should continue to work harder.

Take a breath!

Accumulate learning coins!

He leaned over and pointed to his cheek and laughed, "So, you...hehe, I'll just say it!"

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

"Boom!"

The whole class is watching.

She stared at Zhao Yi straight, and kept rubbing her wrists, pretending to be beating someone, "Should you tell me!"

Zhao Yi knew that Lin Xiaoqing was frightening people. Every time he put on a violent posture, he actually didn't do anything at all, but he still pretended to be afraid and waved his hands continuously and said, "Woman, please! Don't, don't, don't , Haha, I said! I said!"

Lin Xiaoqing sat down with satisfaction.

Zhao Yi said, "In fact, it is 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 the little girls in high school. When they heard Zhao Yi say'continue to invade', they started to chat about how to make changes more interesting.

"You put a picture of an eagle? How boring!"

"It should be another spoof picture!"

"Change the background to the 13th Middle School, then the police website will become the education network..."

Zhao Yi ignored it.

This is really what the little girl said casually.

That's the Zhengyang City Police website, and even the worst is the website of the state department. Even if it is a spoof, there must be a limit, leaving traces to indicate a successful invasion.

When Zhao Yi directly rejected each of the suggestions, they radiated their thinking in other areas.

Zhao Linlin is worthy of being a little witch.

Each of her suggestions made Zhao Yidu listen to it brightly and decided to adopt one of them.

...

It was nine o'clock in the evening.

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

"Changed the password?"

He opened the monitoring software.

The monitoring software was always on, and a lot of content was added in one day, because he knew that the website was restored in the morning, and he found what he wanted without careful screening--

One login ID, several new passwords.

"Is it changed several times?"

Zhao Yi tried passwords one by one, and soon logged in again. He continued yesterday's operation, replacing the big news picture with an eagle animation, and then putting a link to the recorded DJ Divine Comedy.

The next operation is different.

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

If the other party does not know the password, there are two options for modifying it again: either brute force cracking, the technical difficulty is still relatively high; or it is to directly modify the underlying code and upload and load the website again.

The second operation is different from the previous day.

You only need to use the source code to directly overwrite the content of the database the day before, you can remove the Flash animation and link of the eagle, but the modification to the highest level cannot be covered by calling the database, so you must temporarily close the outside access. After the modified source code is uploaded to the server, restart the server.

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

Of course.

It is impossible for Zhao Yi to paralyze the police website for a few hours. He still left a back door 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-consuming, and the average student simply can't do it. Even if it is Sun Liang-level mathematical ability, it will take a long time to think about it.

There is a sentence below the math problem--

[The answer to the question is multiplied by the pi to obtain the final digital code.(Special reminder: if the password has more than ten digits, guessing the answer is meaningless, smiley face)]

After Zhao Yi completed the operation, he intercepted a picture and sent it to Lin Xiaoqing, who asked Lin Xiaoqing to help forward it to Lin Xudong, asking if it was too much.

Lin Xudong smiled immediately when he saw the screenshot.

Math question?

Good idea!

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

opposite.

Zhao Yi glanced at the information on the phone and looked at the computer screen after he was relieved. There was a stranger message on the Penguin.

The security message from the "Computer Technology Exchange Group" is Zhou Ming: "Zhao Yi, do you know about the hacking incident last week? Overseas hackers launched a wave of violent intrusions against our public service peripheral websites."

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

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