Zhao Yi thinks.

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

When he realized that something seemed wrong, he immediately closed the Penguin that had been logged in, found the Penguin's installation folder by the way, and deleted the record folder that had just logged in to the Penguin.

And also.

In the file of the routing monitoring feedback, the penguin number and password are all deleted.

Get!

"So, I didn't do anything, and even if anyone suspected it, I couldn't find any evidence. ”

"Start now, selective forgetting!"

Zhao Yi began to take a serious look at the file of the monitoring feedback, there were a lot of messy contents in the document, most of which were undecipherable garbled characters, he could only look carefully line by line, and extract the information of the 'suspected ID password'.

After reading it all, looking at the more than a dozen IDs and password data in the document, he did not try to log in in a hurry, but modified the source code of the route listening.

Something must be added!

The content of the file listening to the feedback is too complicated, it is time-consuming to read them one by one with the naked eye, and important information may be missed, so he simply added an output applet to group the content of the monitoring.

Web links are a group.

Various login IDs and passwords are set together, and feedback is also marked on the corresponding website and software.

The rest of the mess and gibberish are grouped together.

First of all.

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

After trying more than a dozen times in a row, I finally jumped to log in.

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

Lin Xudong also said that 'the funds allocated from above for network security' can't be used to build a website? Even if you only hire a professional website designer and artist, you can make the quality of the website take off for a few days.

Of course.

Zhao Yi can also understand a little that the information on the police website cannot be modified casually, and many news and information releases must be carefully considered and considered, and there may be secrets involved, which must be managed by internal people.

The rise of the Internet in China is just a few years, and it is too difficult to find someone who is good at website design and maintenance in the police department.

Now that it's invaded, what should we do?

Zhao Yi suddenly thought that Lin Xudong gave a piece of paper, which seemed to be information related to his body, and when he went home, he pressed it under the computer and didn't look at it, so he quickly took it out and glanced at it.

Name: Yi Zhao.

ID number: xxxxxxxxxxxxxxxxxx.

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

Codename: Yiying.

"Yiying?"

"That's a good codename!"

Zhao Yi pondered for a moment and nodded with satisfaction, "I'm 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, make a simple Flash animation, write two words 'Yi Ying' on the top layer, hang it on the news map on the homepage of the website, and set a password to modify the permission by the way.

Embed links.

link...... Music?

Zhao Yi thought about searching for music, found several songs and listened to several of them boring, he listened to a lively dance music, and suddenly thought of the Divine Comedy more than ten years later.

"Otherwise, just sing a few words!"

"That's what makes sense!"

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

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

In that late-night bar, it doesn't matter if it's real or not.

Swing as much as you want, forget the one you love,

You are the most charming Ka, you know?

......

Come to the left and draw a dragon with me

Draw a rainbow on your right (walk)

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, singing without the taste of an old man, but with a little youthful color.

He sang the whole song!

I forgot some words, so I hummed along the tone and added the word 'Yiying' by the way.

Open the web page.

I uploaded the recorded audio and added a picture of a late-night bar DJ.

ok!

That's it!

Zhao Yi closed the webpage happily and continued to write his thesis.

Thesis.

Hurry up and finish it, hurry up and finish!

......

At the same time.

Lin Xudong returned home full of confusion, normally he was on duty today, and he must sleep in the bureau when he sleeps, but his wife was inexplicably angry, and if he didn't go back to coax him, he had to make a fuss, so he could only explain to his colleagues, and go home to see it first.

When he arrived at home, he ushered in a raging storm.

"Lin Xudong, you conscienceless! Tell me! What's going on? Which big beauty are you chatting with!"

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

"What? What else? I have proof. Qingqing, show your dad the penguin news, he still doesn't admit what he said!"

Lin Xudong glanced over, he was really a little stunned with his mouth open, he thought about it carefully, and immediately said suddenly, "I'll just say, why did the Penguin suddenly drop the line, it must have been stolen!"

"Stolen? What kind of bad excuse, you landed in the unit, and someone can hack your unit to steal your number, is he deliberately targeting you? And he happened to reply to me right away? Think about it yourself, is it possible?"

Zhao Hongjuan said very methodically.

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

Wrong!

What followed was a verbal cannon battle between the two.

Women are unreasonable.

Originally, Zhao Hongjuan was not at ease with Lin Xudong, he was a man in his early forties, he was square and a little handsome, and he was the captain of the Criminal Investigation Department, he would definitely face a lot of temptations, maybe there would be a little girl who had a secret affection for him.

She also took this opportunity to vent.

Lin Xudong explained at the beginning, but in the end, he could only bow his head and admit it, and simply listened depressedly.

Men are like that.

It's like a joke on the Internet that says, "I want to write an apology letter to my wife, but after looking at the blank paper for a long time, I can only write the words 'I was wrong', because I don't know what I did wrong." ”

Lin Xudong didn't know what to do.

The phone rang.

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

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

"What!"

"Xiao Zhang?"

Lin Xudong reminded him vigorously, and the other side finally spoke, his voice was a little excited, "Team Lin, the police website has been hacked, it's the Yiying you recommended, it's amazing." ”

"Yiying?"

"Yes!"

Xiao Zhang gloated and said, "Team Li also said that they found a few computer geniuses, but what was the result?

"Also, this Yiying is really interesting, he sings very well, do you know what this song is? I searched the Internet for a long time but couldn't find ......"

Lin Xudong put down his phone in a comfortable mood.

There is also competition in various police departments, competition in solving cases and investigations is one thing, and there is also competition in other work, and the upper authorities have always attached great importance to websites, network information, etc., but it is almost impossible for police to come up with professional talents.

Now in the work of testing the security of the website, the extent to which the 'credible person' can be found is also a kind of direct competition, and the above must care about who has broken the website.

When the time comes, when asked, it will be mentioned, "This person was recommended by Captain Lin." ”

That's what it takes.

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

......

The management of the Zhengyang police website is Li Jiandong of the logistics department, who has a bachelor's degree in computer science, and did not go out to look for a job after graduation, but signed up for the police academy and entered the public security department.

When the police website was built, the logistics department was directly found, and Li Jiandong was directly responsible for managing and maintaining the website.

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

The above deliberately improved the security of the network, and found a special computer expert to try to attack the website to find vulnerabilities.

This is a test of the security of the website, and it is also a test of Li Jiandong's work.

Li Jiandong didn't particularly care.

He is not a professional network security person, but because he is responsible for managing and maintaining the website, and he also understands some hackers' methods, the website was attacked some time ago, and the server was only paralyzed for a while.

This brute force attack is related to the performance of the server, and there is no way to fight it, but to upgrade the performance of the hardware, but even if it is attacked by brute force, it will not have much impact.

At most, restart the server.

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

This evening.

Li Jiandong routinely looked at the website before going to bed, and suddenly he was not sleepy at all, the picture of the main page leader inspection was tampered with, and a flash animation of an eagle flying was played.

"Yiying?"

Li Jiandong clicked on the picture and found the link.

A cappella weird song was played, and the more Li Jiandong listened to it, the more irritated he became, and the fact that the web page was tampered with means that it had been breached, doesn't it directly mean laughing at his work?

Li Jiandong hurriedly logged in to enter the management page and wanted to modify the webpage back, but after clicking in, 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 could not modify it for the time being, and he had to go to the computer in the bureau to find the source code 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 a security vulnerability, and after the vulnerability is patched, the security will naturally be improved.

Li Jiandong didn't want to do that.

If the other party reports the security vulnerability, the above will definitely know, which is equivalent to drawing an 'X' on his work, and he and the logistics department will lose face.

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

And he knew the problem --

The other party must have entered the management page to make so many modifications, and 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, it is impossible for the other party to crack it easily.
