Rule system

"The safety information is Zhou Ming?"

Staring at the name on the screen, Zhao Yi pressed his mouth vigorously.

This name impressed him deeply.

After completing the creation of the Rubik's Cube calculator, he put the download link in the group. After a while, he saw the discussion in the group.'Safety information is Zhou Ming' is one of them.

Others are discussing the effect of the Rubik’s Cube calculator and the possible secrets of the algorithm. Zhou Ming is a very different one. He constantly complains to the group of friends, "The recharge of the webpage and the entrance to unlock the password are too designed. Simple, I cannot complete the invasion at all.'

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

This guy is absolutely abnormal.

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

"Network and Information Security Center?"

"State department, right?"

After thinking, Zhao Yi replied, "What group, pull me." He wanted to go in and take a look.

"Add a friend."

Zhou Ming sent a friend message, and after adding a friend, there was an invitation to pull the group, and he also sent a sentence, "Enter the group and change your name. Don't use your real name, use the code name."

"it is good!"

Zhao Yi clicked to agree.

The name of the group is'The League of Hearts Group', which is a large group of two hundred people. After Zhao Yi entered, there were just two hundred people. It seems that if there are new people who want to come in, he has to give up a position first.

Zhao Yi quickly changed the group name and simply called it'Yiying'. Upon closer inspection, he found that his name was prefixed with'[Special Invitation]', and the name in 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'[Red A] Ming Ge'.

"This name takes advantage of..."

Zhao Yi vomited and shook his head, and carefully looked at the information in the group. The announcement of the group was very interesting. It said, "This group is for hacker technical exchanges, please consciously respect laws and regulations."

The names in the group member list all carry the word [heart], from [2 of hearts] to [heart ace], and several of them are prefixed with [special invitation] just like him.

quickly.

Someone in the group spoke.

"Another special invitation, another great god!"

"Ming Ge pulls in, it must be a great god, no doubt, great god, kneel for guidance!"

"God speak~"

"The specially invited gods all have a cold face!"

Many people came out to speak.

Zhao Yi just dived and watched, flipping through the group files. The group files were very interesting. Many of them were hackers and intrusion-related knowledge, and some people shared some simple detection and auxiliary software.

He took a closer look and found that it was of little use.

Although he has not studied hacking technology seriously, every programmer has the heart to be a hacker. He still has a simple understanding. Hacking is a profession with extremely low barriers to entry, and the level of technical polarization is very serious and truly high. The hackers are all high-level computer experts and programmers. The top hacking knowledge and intrusion methods are definitely related to computer knowledge. The so-called "hacking technology" in group sharing is just the application of a few software. There are also operations such as hacking websites and placing Trojan horses.

The issue is……

Invading a website is only a guide to basic practices; the key is to launch a Trojan horse.

The chat in the group continued, and the speakers were all below the [Ten of Hearts] level, "I bought two hundred penguin accounts to draw the lottery, and after several hours, nine penguin coins were issued. Twenty yuan!"

"You're so stupid, buy that too!"

"What if you are lucky?"

"I set up interception for the routing at home. I want to know whether my sister talked about her boyfriend, but the penguin messages intercepted are all garbled. Which great god has a way to crack it?"

"This is no way!"

"You see there is a bbs website here, you can log in with a simple injection, let's hack it together, right?"

"Don't cause trouble!"

"People are forums with edu suffix!"

Who are these people?Buy penguin accounts sold online?Set up route interception just to crack sister's penguin information?Summon people to go to the black forum website together?

Expect these people to launch a counterattack against overseas networks?

Zhao Yi suddenly felt a little unreliable. He still didn't leave the group directly. Instead, he silently closed the group chat page and set up a "receive but no message".

It is quite now.

Then start work.

The paper has been written to the last part. After you have finished writing it, review it, make some corrections, correct some minor errors, etc., and you can almost submit it.

Zhao Yi chose the journal for submission: "Journal-of-the-ACM".

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

The content published in "Journal-of-the-ACM" focuses on purely theoretical things such as algorithms, complexity, graph theory, combinatorics, and so on. It is difficult for papers in other fields to enter.

The'effective and irrelevant carry screening method' is an algorithm of correlation complexity and data mining. Because of the influence of the Rubik's Cube calculator, it has been paid attention to by many people before it has been published.

Professor Liu also thinks it is very suitable for publication in "Journal-of-the-ACM". He also knows a review editor of "Journal-of-the-ACM". He said that Zhao Yi would say hello after submitting the manuscript and it would be completed as soon as possible. Review the manuscript and publish it.

...

The next morning, the Zhengyang police department became lively and everyone was talking about the'website hanging eagle incident'.

The police website was hacked once. After modification and improvement, it was hacked again only a day later. Some people who knew something about it were gloating at the logistics department.

I ordered the police to upgrade the network security. I also found a trusted computer expert to attack the police’s network and website. The “Yi Ying” recommended by Captain Lin entered the website. The normal process is to submit a problem and then modify it. Perfection means upgrading.

The results of it?

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

This is too much.

If you know the vulnerability, you can’t report it, and the computer expert you find will not get the bonus. Money is only one aspect, and reputation is the most critical issue.

Outsiders 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 ashamed again. The director of logistics, Zhou Hongwen, was not embarrassed to leave the office again. He called again and again to ask, "Is Li Jiandong here!"

"Hurry up when he comes!"

Maybe it was because of too little time to sleep yesterday. Li Jiandong got up a little bit late. He came to the office by stepping in. When he entered, he found that the atmosphere was a bit wrong. The eyes of other people looked at him with a sense of amusement.

A logistical colleague pulled him and said, "The website is hacked again. It's still'Yiying'. Director Zhou is getting angry. Go ahead!"

Li Jiandong hurried to the director's office.

"what is the problem!"

As soon as Zhou Hongwen saw Li Jiandong, the fire in his stomach couldn't hold back. "Didn't you say that you found the problem yesterday? Why did it happen again today?"

Li Jiandong lowered his head and said nothing.

He also couldn't understand.

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

Yes indeed!

The website management entrance should be hidden!

Li Jiandong wanted to understand, and immediately said, "Director Zhou, I know, the entrance should be hidden, so that the other party doesn't even know the entrance, so it must be impossible to invade."

Zhou Hongwen shook his head and waved his hand.

The reason Zhou Hongwen was angry was not just that the website was breached again, he mainly fought for Li Jiandong, and after the website was breached again, he made himself difficult for him.

He is the director and the leader!

Yesterday, I just forcibly suppressed the matter. I regretted and bowed my head because the website was breached again?

That will definitely not work!

Zhou Hongwen didn't know what to do for a while, did he continue to force the matter down, or he repented and bowed his head, letting Lin Xudong recommended'Yi Ying' report?

The former is risky, the latter loses face.

Zhou Hongwen stared at Li Jiandong earnestly, and asked, "Jiandong, I have always believed in you and in your skills and abilities. Now I will ask you one sentence. After you have changed the entrance, the other party will not be able to hack into us. 'S website?"

Li Jiandong knew the key was coming.

He gritted his teeth and nodded, "Director Zhou, no problem, as long as the website's management page entrance is hidden, the other party can no longer hack in. Look, the few computer experts we looked for didn't do anything? "

Zhou Hongwen nodded as he listened.

indeed.

Among them, there is a computer expert who he found on his own. He is an associate professor of the School of Information of Zhengyang University. Zhengyang University is only an ordinary undergraduate college, but the associate professor of the School of Information must be very good.

The'Yi Ying' that Lin Xudong looked for didn't know who it was, but what computer expert could Lin Xudong, a detective detective, know?

Definitely not comparable to the associate professor of Zhengyang University!

Zhou Hongwen took a deep breath and said seriously to Li Jiandong, "I will believe you again. If the website is compromised again, whether it is embarrassing or whatever, we must go through the process."

"I guess all of the above is known now, but it's just to save me face, do you understand?"

"My face is on this matter!"

Zhou Hongwen felt very depressed when he said that. He didn't even know who'Yi Ying' was. As a result, he lost a lot of face in the bureau for the sake of this website. It was not worth thinking about.

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

He originally thought that just like yesterday, calling the database to overwrite the picture would be fine, but found that the database overwrite didn't work, and the picture could only be unlocked with a password.

What to do?

Do you really do math problems?

Li Jiandong looked at the math problem and felt a little scalp numb. He sent a screenshot of the problem to the group of the logistics department. The suggestions he received made people vomit blood, "Jiandong, or you take the problem to Zhengyang No. 1 Middle School. ?"

"Ninth Middle School next to you is fine too!"

"Thirteenth Middle School is also not bad. My primary school classmate, Sun Zhiguo, his son is very good in his studies. He has also been admitted to the province to participate in competitions in mathematics!"
