The big picture of the news of the Zhengyang police website was hung with a flash animation of an eagle flying, and it was still a cappella DJ dance music when clicked in.

This matter is known to many people.

People outside know less, the police website has not been established for a long time, it is only used to release some information, and it does not provide any convenient services, and few people will click in to see it.

The people who work in the police department, from the leaders of the department to the cleaning aunts who clean the stairs, know it.

A lot of people talk about it in the morning, and most people just laugh at it.

It's not a secret that the site is undergoing a security upgrade, but the logistics department hasn't posted it on the site, and they're more interested in the cappella DJ.

Although there is no soundtrack that sounds weird, the tone and lyrics are very interesting.

Many people also know the name of 'Yiying'.

"Who is this Yiying? Captain Lin recommended it, it was really powerful, and he broke through the website in one day. ”

"The group of people in the logistics department, they don't know what websites and security are at all, if you want me to say, these new things, scientific and technological things, you have to find special people to manage, such as this Yiying, recruit in, it will definitely 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, and he still logged in to the computer in the office. ”

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

The logistics people must not be happy to hear it.

Li Jiandong came earlier than everyone else, entered the office at six o'clock, turned on the computer to find the source code, and called the contents of the database to overwrite the modified pictures and links, because of the Internet speed and the impact of the wrong operation, the website was paralyzed for more than ten minutes.

Of course, it doesn't matter.

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

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

Morning.

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

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

Zhou Hongwen also makes sense when he thinks about it.

The website of the police department is managed by the logistics department, knowing that the vulnerability can be directly patched, there is no need for the other party to submit it, and the record of 'being reported by outsiders' is also a small stain on the work of the logistics department.

More mainly......

'Yiying' is a person recommended by the Criminal Investigation Department, not recommended by the logistics department, the above meaning is that all departments can recommend people, but a group of detectives from the Criminal Investigation Department, the recommended person actually broke the website, and the person recommended by the logistics department didn't even do anything?

That's a slap in the face!

Zhou Hongwen decided to trust Li Jiandong and did not follow the established process to report.

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

Midday.

Lin Xudong called Zhao Yi and talked about the morning's events with apologies, "You succeeded yesterday, but you were pressed down by logistics, and the things inside are a bit complicated, so I won't tell you in detail." ”

"Anyway, I'm really sorry. Well, I'll personally reward you with a thousand dollars. ”

Zhao Yi was a little surprised when he heard it.

Originally, he thought it was over.

He made a routing monitoring software, broke the website of the police department, submitted the problem according to the process, reminded the police to hide the entrance to the management website, and upgraded the security and encryption of the route, and his work was completed.

He didn't care about how much money he could get for this job.

A few thousand dollars is nothing, an hour of leisure and part-time work, even if there is no penny, it can be regarded as helping the police department and improving network security.

Sound...... It's kind of great!

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

That's not great, it's sick.

Hearing Lin Xudong's explanation, Zhao Yi was a little secretly unhappy, even if he didn't care about the bonus, he couldn't be pressed like this, right?

"No, Uncle Lin. Zhao Yi refused and asked, "Then do you still need me to help?" Why don't I go back today and put up a picture on your website?"

"Can you still go in?" Lin Xudong was a little surprised.

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

"I don't know. ”

Lin Xudong didn't understand the problem of network technology, but he knew that the logistics had suppressed the matter, which seemed to have found a loophole, and he also felt very depressed, and when he heard Zhao Yi say that he could still go in, he suddenly said with some anticipation, "If you don't delay your time, you can try again, make it bigger, it's okay, don't worry, with you Uncle Lin and me!"

"I have already reported your name, and the police know that 'Yiying' is their own person. ”

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

"Thank you in advance. ”

Zhao Yi put down the phone with a smile.

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

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

Lin Xiaoqing pricked up her ears, she almost exploded when she heard the word 'secret', she sat up and pouted, "You don't even say it, what are you doing mysteriously." ”

Zhao Yi said with a smile, "If you have a fragrance on your body, I'll smell it!"

"What are you talking about? shameless!"

Lin Xiaoqing's face flushed when she heard this, and she quickly turned her head over, and only turned around after a while, and still couldn't hold back her curiosity with a light 'hum', "What the hell is it doing, tell me." ”

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

Breath!

Accumulate Learning Coins!

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

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

"Bang!"

The whole class looked at it.

She stared straight at Zhao Yi, and kept rubbing her wrists, posing as if she was going to beat someone, "Do you want to say it or not!"

Zhao Yi knew that Lin Xiaoqing was just scaring people, and every time he put on a violent posture, he actually didn't do it at all, but he still pretended to be afraid, and kept waving his hand and said, "Woman, spare your life! Don't, don't, don't, haha, I say!"

Lin Xiaoqing sat down satisfied.

Zhao Yi said, "Actually, it's not a secret, some time ago, Zheng Yang's police website was ......hacked," he said briefly.

Zhao Linlin also stuck her head over and gossiped.

This kind of thing is so interesting for a little girl in high school, and when she heard Zhao Yi say, 'Continue to invade', they chattered about how to modify it more interesting.

"You just put a picture of an eagle, how boring is that!"

"It should be a different spoof picture!"

"Change the background to the 13th middle school, and then the police website will become an education network ......"

Zhao Yi ignored it.

This is really a little girl talking casually.

That's the Zhengyang City Police website, no matter how bad it is, it's also the website of the state department, even if it's a spoof, there must be a limit, and leaving traces shows that the successful invasion is OK.

When one suggestion after another was directly rejected by Zhao Yi, they diverged their thinking in other aspects.

Zhao Linlin deserves to be a little witch.

The suggestions she put forward made Zhao Yidu's eyes light up when he heard it, and he decided to adopt one of them.

......

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

Zhao Yi rushed to the computer when he got home on time, opened the management page of the police website, and logged in and found that he couldn't get in.

"Changed your password?"

He turned on the listening software.

The listening software was always on, and there was a lot of content in a day, because he knew that the website was restored in the morning, and he didn't have to sift through it carefully to find what he wanted.

A login ID, a few new passwords.

"Did you change it several times?"

Zhao Yi tried one password after another, and soon logged in again, he continued yesterday's operation, replaced the news picture with the animation of the eagle, and put a link to the recorded DJ Divine Comedy.

The rest of the operation is different.

He raised the permission to modify images and links to the highest level, and can only modify them from the source code repository.

If the other party doesn't know the password, there are two options to modify it: either brute-force cracking, which is still relatively technically difficult, or directly modify the underlying code to upload and load the website again.

The second operation is different from the previous day.

The day before, you only need to use the source code to retrieve the content of the database and directly overwrite it, and you can remove the Flash animation and link of the eagle, but if you raise it to the highest level of modification, the database cannot be covered by calling it, so you must temporarily close external access, modify the source code and upload it to the server, and then restart the server.

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

Of course.

Zhao Yi couldn't have to paralyze the police website for a few hours, but he still left a back door for recovery.

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

This function problem is very brain-burning, and ordinary students can't do it at all, even if it is Sun Liang's level of mathematical ability, it takes a long time to think and meditate if you want to do it.

There's a notation at the bottom of the math --

[The answer to the question is multiplied by pi, which is the final numerical password.] (Special reminder: the number of digits of the password is more than ten, and there is no point in guessing the answer/smiley)]

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 and ask if it was too much to do this.

Lin Xudong immediately laughed when he saw the screenshot.

Math problems?

Good idea!

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

Opposite side.

Zhao Yi glanced at the information on his phone, and looked at the computer screen after being 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 last week's hacking incident? Overseas hackers have launched a wave of violent intrusions against the peripheral websites of our public services. ”

"We're preparing to organize a counteroffensive in the middle of next month, would you be interested in getting involved?"

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