Genius of the Rules-Style System

"The security information is Zhou Ming?"

Staring at the name on the screen, Zhao Yi pursed his lips hard.

The name made a deep impression on him.

After completing the Rubik's Cube calculator, he put the download link in the group. Soon after, he saw discussions in the group, and one of them was "The security information is Zhou Ming."

Others were discussing the effects of the Rubik's Cube calculator and the possible algorithm secrets inside. Zhou Ming was a very different person. He kept complaining to the group of friends, "The recharge and password unlocking entrances on the webpage are too well designed." Simple, I simply can't complete the invasion'.

At that time, Zhao Yi wanted to complain, "I'm so sorry! I didn't let you hack in..."

This guy is definitely not normal.

Zhao Yi clicked on the information on 'Security Information is Zhou Ming' and found that there was only a brief introduction on it: Network and Information Security Center.

"Center for Network and Information Security?"

"National department, right?"

Zhao Yi thought about it and replied, "What kind of group? Pull me here." He thought about going in and taking a look.

"Add a friend."

Zhou Ming sent a friend message. After adding the friend, there was an invitation to join the group. He also sent a sentence, "Join the group and change your name. Don't use your real name, use a code name."

"good!"

Zhao Yi clicked to agree.

The name of the group is 'Heart Alliance Group', it is a large group of 200 people. After Zhao Yi entered, it just reached 200 people. It seems that if there are new people who want to join, they have to give up a place first.

Zhao Yi quickly changed the name of the group and simply called it 'Yi Ying'. After a closer look, he found that his name was prefixed with '[Special Invitation]', and the name of the group became '[Special Invitation]' 】Yi Ying'.

The prefix of the group name must have been modified by Zhou Ming. He is the administrator of the Heart Alliance group, and his name is ‘[Ace of Hearts] Brother Ming’.

"This is a name for taking advantage..."

Zhao Yi complained and shook his head. He looked carefully at the information in the group. The announcement in the group was quite interesting. It said, 'This group is for hacker technology exchange. Please respect the laws and regulations.'

The names in the group member list all have the word [Heart], ranging from [Two of Hearts] to [Ace of Hearts], and there are also a few with the prefix [Special Invitation] like him.

soon.

Someone in the group spoke.

"Another special invitation, another great master!"

"The person who came in Mingola must be a great god. Great god, please kneel down and ask for advice!"

"God has spoken~"

“The specially invited masters all have a cold face!”

Many people came out to talk.

Zhao Yi just dived and watched while flipping through the group files. The group's shared files were very interesting. Many of them contained knowledge about hackers and intrusions. Some people also shared some simple detection and auxiliary software.

He looked at it carefully and found that it was of little use.

Although he has never seriously studied hacking technology, every programmer has had the desire to be a hacker. He still has a simple understanding that hacking is a profession with extremely low entry barriers. The technical level is very polarized, and truly high-level Hackers are all high-level computer experts and programmers. The top hacker knowledge and intrusion methods are definitely related to computer knowledge. The so-called 'hacking technology' in group sharing is just the use of a few software. There are also some operations such as invading websites and placing Trojans.

The issue is……

Invading a website is only a guide to basic practices; placing Trojans in Trojans is the key.

The chat in the group is still going on, and the people who are speaking are all at the level of [Ten of Hearts] or below, "I bought two hundred Penguin accounts to draw the lottery. After working on it for several hours, I got nine Penguin coins. I lost a lot." !Twenty yuan!"

"You're so stupid, you bought that one too!"

"What if I get lucky?"

"I set up interception on the router at home. I want to know whether my sister is dating her boyfriend, but the intercepted penguin messages are all garbled. Does anyone have a way to crack it?"

"There's nothing we can do about it!"

"Look, there is a bbs website here. You can log in with a simple injection. Let's hack it together, right?"

"Stop causing trouble!"

"This is a forum with the suffix edu!"

Who are these people? Buy Penguin accounts sold online? Setting up routing interception just to decipher my sister’s penguin information? Summon people to hack the forum website together?

Expect these people to launch counterattacks on overseas networks?

Zhao Yi suddenly felt a little unreliable. He still did not leave the group directly. Instead, he silently closed the group chat page and set up a 'receive but do not prompt for messages' setting.

It is quite now.

Next get to work.

The paper has been written to the final part. After it is all written, I will review it, make some minor corrections, correct some minor mistakes, etc., and then it is almost ready for submission.

Zhao Yi has chosen the magazine to submit to: "Journal-of-the-ACM".

ACM refers to the International Computer Association. "Journal-of-the-ACM" is the official journal of the International Computer Association, and its industry impact factor is relatively high.

The content published in "Journal-of-the-ACM" focuses on purely theoretical things such as algorithms, complexity, graph theory, combinatorial mathematics, etc. It is extremely difficult to enter papers in other fields.

The 'valid and irrelevant carry screening method' is an algorithm related to complexity and data mining. Because of the influence of the Rubik's Cube calculator, it has attracted the attention of many people even before it was published.

Professor Liu also thinks that it is very suitable for publication in "Journal-of-the-ACM". He also knows a review editor of "Journal-of-the-ACM" who said that Zhao Yi can complete it as soon as possible if he says hello after submitting it. Review and publish.

…

The next morning, the Zhengyang Police Department was bustling with activity, and everyone was talking about the ‘website hawking incident’.

It didn’t matter if the police website was hacked once. After modifications and improvements were made, it was hacked again just one day later. Some people who knew something about the situation were gloating about the logistics department’s misfortune.

The superiors ordered the police to upgrade their network security, and also found trustworthy computer experts to attack the police's network and website. The 'Yiying' recommended by Captain Lin hacked into the website. The normal process is to submit the problem and then modify it. Perfection is tantamount to upgrading.

The results of it?

The logistics department suppressed the matter, which basically meant, "We know the problem, so we don't need to report it."

This is too much.

If you know the vulnerability and don't report it, the computer expert you find will not get the allocated bonus. Money is only one aspect, credibility is the most critical issue.

If people outside know about this, who will help the police in the future?

it's good now.

The police website was hacked again, and the logistics department was once again embarrassed. The director of logistics, Zhou Hongwen, was too embarrassed to leave the office again. He called again and again to ask, "Is Li Jiandong here?"

"Hurry over here when he comes!"

Perhaps it was because he had too little sleep last night. Li Jiandong got up a little late and came to the office on time to go to work. When he entered, he found that something was wrong with the atmosphere. The looks in other people's eyes were somewhat funny.

A logistics colleague pulled him and said, "The website has been hacked again, and it's 'Yiying' again. Director Zhou is getting angry. You should go quickly!"

Li Jiandong hurried to the director's office upon hearing this.

"what is going on!"

When Zhou Hongwen saw Li Jiandong, he couldn't hold back the fire in his stomach. "Didn't you say you found the problem yesterday? Why did there be another problem today?"

Li Jiandong lowered his head and said nothing.

He couldn't understand either.

Even if the website's management entrance is leaked and a new password has been changed, only he knows the password. How did the other party get the new password quickly?

yes!

The website management entrance should be hidden!

Li Jiandong figured it out and immediately said, "Director Zhou, I understand. The entrance should be hidden, so that the other party doesn't even know the entrance and will definitely not be able to invade."

Zhou Hongwen shook his head and waved his hands.

The reason why Zhou Hongwen was angry was not only that the website was breached again, but also that he mainly fought for Li Jiandong. After the website was breached again, he became very difficult to get off.

He is the director, the leader!

You just suppressed the matter yesterday, and now you regret it and bow your head because the website was hacked again?

That definitely won’t work!

Zhou Hongwen didn't know what to do for a moment. Should he continue to suppress the matter forcefully, or should he regret it, bow his head, and let the "Yi Ying" recommended by Lin Xudong report it?

The former is risky, the latter is faceless.

Zhou Hongwen stared at Li Jiandong seriously and asked, "Jiandong, I have always believed in you, your technology, and your ability. Now I want to ask you something. After you are sure that you have changed the entrance, the other party will not be able to hack into us again." website?"

Li Jiandong knew the key was coming.

He gritted his teeth and nodded, "Director Zhou, no problem. As long as the entrance to the website's management page is hidden, it's impossible for the other party to hack in. Look, haven't the computer experts we found accomplished nothing? "

Zhou Hongwen nodded as he listened.

really.

Among them was a computer expert who he found through his own connections. He was an associate professor at the School of Information at Zhengyang University. Zhengyang University was just an ordinary undergraduate institution, but the associate professor at the School of Information must also be very capable.

I don’t know who the ‘Yi Ying’ Lin Xudong is looking for is, but Lin Xudong, a detective investigating the case, can know any computer masters?

Definitely not as good as the associate professor at Zhengyang University!

Zhou Hongwen took a deep breath and said seriously to Li Jiandong, "I will trust you again. If the website is breached again, no matter it is embarrassing or something, we must go through the procedures."

"I guess the higher-ups know about it now, but they just wanted to save my face and didn't expose it. Do you understand?"

"My face is all about this!"

Zhou Hongwen felt very depressed as he spoke. He didn't even know who 'Yi Ying' was. As a result, he lost a lot of face in the bureau because of the website matter. No matter how he thought about it, it was not worth it.

Li Jiandong hurriedly issued a military order and then went to modify the code.

He originally thought that just like yesterday, he would just call the database to overwrite the picture, but found that the database overlay did not work, and the picture could only be unlocked with a password.

What to do?

Do you really have to do math problems?

Li Jiandong felt a little numb when he looked at the math problem. He sent a screenshot of the problem to the group of the logistics department. The advice he received made people vomit blood, "Jiandong, you can either go to Zhengyang No. 1 Middle School with the problem and ask. ?”

"The Ninth Middle School next door is fine too!"

"No. 13 Middle School is also pretty good. My elementary school classmate Sun Zhiguo's son is very good at studying. He even passed the provincial math competition to participate in the competition!"
