"Put this loophole again, and then like this, it should be almost done..."

Ji Wenzhong is obviously a technical man. He doesn't talk much when chatting, but when he talks about technology, he immediately becomes confident. The keyboard and mouse in his hand keeps stopping for a moment. He quickly patched the system a lot, and downloaded several small software he made from the network disk, and directly added a few more "walls" to the system. ←

He Dongcheng's eyes are almost too low. He is a computer application. Although he is still a rookie in programming, he has been practicing application knowledge in recent years. Not only has he increased the typing speed to more than 90, but he is also very clear about the functions of all aspects of the system and some common loopholes. He thought he was at least half an expert, but when he looked at it today, he found out that he was at most to get started!

It turns out that the system has so many backdoors, and it turns out that it is so easy to modulate, and there are such shortcuts!

Looking at the dialog boxes popping up after those small software applications, He Dongcheng felt for the first time that programming can play such a big role!

At this moment, He Dongcheng was actually grateful: Fortunately, he came with him and asked to study. If he didn't come, he would regret it later!

"Do you have any more?" Ji Wenzhong asked He Dongcheng politely. He Dongcheng shook his head quickly and joked, how could he add it? Even the teacher who taught him might not be so skillful!

Before Ji Wenzhong could speak, Dong Xiuxiu clicked two more places. Although these small loopholes did not have much impact, both of them had heard Hongxing say that Lin Dong was so powerful that he did not dare to be careless at all.

Lin Dong had already compiled the software there and was browsing the web page. Seeing that they stopped, they immediately started to operate.

Hackers' offense and defense were originally a battlefield without gunpowder. The mouse and keyboard were all slashed with swords. When they saw Lin Dong's operation, the three people on the opposite side immediately became nervous. Although they were very confident, Lin Dong's reputation had already reached their ears and they couldn't help but take it seriously.

"Is there anything that needs to be added?" Dong Xiuxiu did not come to see Lin Dong's operations immediately, but planned to strengthen defense first. She asked Ji Wenzhong: "For example, remote control, log files and software vulnerabilities now?"

Ji Wenzhong thought about it and shook his head: "I have thought of all the places that can be sealed. If there is anything else, we can only blame our lack of skill. Let's go and take a look!"

When Lin Dong heard that they were going to come and take a look, he let go and slowed down the operation. After the three of them surrounded him, he started the small software again and directly opened a small window to show the operation process.

"This...how is this possible?"

Looking at the software pointer and line of data appearing in the small window of Lin Dong’s computer desktop, Dong Xiuxiu and Ji Wenzhong were both stunned!

It's completely like artificial intelligence. The software comes with a search IP, and after finding the machine, it directly links it, cracks one series of protection programs, enters the machine opposite "swagger", and then starts to modify permissions and browse files... The protections that the three of you just added, including the antivirus and protection software that the computer itself comes with, are like a big sieve, with loopholes everywhere!

They have checked the computers here before. They know that they don’t bring any other programs. When Lin Dong came here, he might not be able to directly download things from the network disk. The small software compiled in such a short time is so powerful?

On the contrary, He Dongcheng, who doesn’t understand programming, still doesn’t understand Lin Dong’s software’s power. He just wondered why these two people reacted so much?

Of course the reaction was huge!

For any programmer, the current version of the system is usually very complete, and companies such as Microsoft will patch the system from time to time to ensure that the system is running normally. Hackers around the world are also looking for vulnerabilities in these systems, but whether they are for money or for the sake of Microsoft, the system will eventually become more and more perfect and fewer vulnerabilities.

Therefore, every mature system is basically perfect for application, and there are very few vulnerabilities that can be exploited, especially under the current programming conditions. Once such vulnerabilities are discovered, they will usually attract the industry's focus.

However, here, Dong Xiuxiu and Ji Wen discovered that the system they once thought was a template for the industry was full of loopholes!

How is this possible?

When they saw Lin Dong easily get the administrator authority of the computer opposite, they were stunned. Dong Xiuxiu felt a little confused. He was wondering, this person was not cheating, right? This cracking speed, even in the Pentagon where the defense is tightly protected, there may not be any secrets?

"This is just a small test." Lin Dong was very satisfied with the performance of the three people. He pushed the keyboard and said with a smile: "If you want to have a large application, this kind of small software is still not enough to watch. It is just to give you an intuitive demonstration that you will program like this. As for what you have to learn later, in addition to the basics, there are also some professional application software. It depends on your understanding at that time!"

"Can I ask a question?" Ji Wenzhong pushed his glasses and suddenly asked, "I want to know how your software works. This is not kept secret from us, right?"

Lin Dong scratched his head. After all, he was just a history student. Although he liked computers, it was not a strong point. He inherited so much knowledge in his mind. However, if he came up with this kind of programming principle at once, it would not be easy to explain it thoroughly.

Thinking of his major, Lin Dong smiled and said, "When I start to explain basic programming knowledge to you, it will be involved. I think what you want to know now is probably why I can break your machine so quickly, right?"

Dong Xiuxiu and Ji Wenzhong nodded repeatedly.

Lin Dong slapped his face: "This is easy to say. Let's say this, machine language is implemented by 0 and 1, right?"

The three nodded.

"But to implement functions, programming languages ​​must be added with logical languages, especially English programming, with pre-suffixes and fixed formats, right?"

Nodded again.

"This is to make machine language easy to recognize, but it also occupies some resources." Lin Dong said the most bluntly in his own way: "And you should know that the Chinese I Ching Bagua was originally composed of virtual and real, and could also be converted into zero and one. In fact, if you use analogy, the language I use is ancient Chinese, and you use modern vernacular Chinese. From the perspective of my ancient Chinese, your vernacular Chinese expresses a meaning, wasted too many words. In fact, three words can express it, you have to use dozens of words. So, in my opinion, every word between the extra lines is a loophole!"

So that's it!
