- Chapter 90: Sudden Enlightenment (3)
After getting Zhao Li's permission, Zhang Yang sat in front of the computer with a smile and restarted the computer. While restarting the computer, he turned his chair around. Zhang Yang said with a smile: "svchost.exe is a good process. It's actually quite good. , Oh, by the way, especially the system dynamic link library files, and there is also a system service that is very good."
Following Zhang Yang's words, Shao Jianglin's calm face finally changed. When Zhang Yang saw the blue screen prompt, he felt a little familiar. The system blue screen and the blue screen prompt were different. Just when he saw the blue screen prompt, Zhang Yang felt very familiar. , but I can¡¯t remember where I saw it.
Just after Shao Jianglin finished speaking, Zhang Yang suddenly remembered that he had seen this blue screen somewhere. It was a vulnerability in a dual-core CPU model of Intel that was discovered a few years later, or a small one. Bugs are fine, in fact, they are harmless. That is, under certain conditions, if this CPU rewrites and sets a system service, and then uses an ASUS motherboard, a small loophole will appear between the two, and this loophole will cause Just the question.
That system service is very partial. It can be said that even those who use computers professionally will never use it for ten thousand years. However, turning it off will affect some performance and functions, so most people will never use it even for ten thousand years. Also left it open, and whoever discovered the vulnerability a few years later did so by coincidence.
But there is actually no difference between having this kind of vulnerability and not having it, and at that time, very few people were using this CPU and motherboard. Zhang Yang only saw it when he was researching intrusions and compiling a list of various vulnerabilities. Zhang Yang has a good temper. If he finds something he is interested in, he will do it without hesitation. At that time, Zhang Yang went to the second-hand computer market to buy such a board and CPU, and then personally tested the vulnerability.
However, this loophole cannot be exploited at all. Zhang Yang quickly forgot about it after the experiment. He did not expect that he would see this thing when he was reborn six years ago. Just from this loophole, Zhang Yang knew that Shao Jianglin's computer skills were good, and they were definitely not comparable to those of freshmen.
This loophole is so weird that if you weren¡¯t idle and knew a lot about computers, who would have figured it out? In particular, it is only the Intel CPU with the ASUS motherboard that has this problem. This kind of vulnerability the chance of discovery is too small.
"I said, buddy, don't pretend to understand. Lenovo's computers are inherently rubbish, right? What advantages does Lenovo have? The monitor belongs to others, the keyboard and mouse belong to others, the chassis and grinding tools also belong to others, not to mention the motherboard. The motherboards they produce are garbage, not to mention servers and high-performance servers. The printers are also OEM, and even the labels are produced by others. Does it produce anything itself? I just support domestic production, so I came to buy it. If you have your own problems, why don't you blame me?" Shao Jianglin said with a sneer.
Zhang Yang immediately laughed. He didn't expect that this girl was still an angry youth. Although angry youth has basically become a derogatory term now, a large number of angry youths will become extremely outstanding people. Don't think that angry youths are really worthless. Those who have never been angry , how good can you expect someone to be who is indifferent to everything around him? Most people who have abilities have character.
"I said, buddy, let's not change the subject. I admit that you are right, but it has nothing to do with the computer. The computer itself has some problems, but if you don't do anything about these problems, It will definitely not affect your use. After all, you still did it yourself, so if I fix the computer, this matter will be forgotten?" Zhang Yang asked with a smile.
Looking at Zhang Yang¡¯s calm smile, Shao Jianglin was a little confused. Did he really know about this loophole? Impossible. Almost no one has discovered this thing. He only discovered it from another friend by chance.
"You have to do it right. I apologize for being unreasonable." Shao Jianglin sneered, then looked at Zhang Yang and said every word.
"Okay." Zhang Yang didn't talk nonsense to him. Although the PE system used by the master just now would have a blue screen when starting the software, when the system is installed on the computer itself, starting the PE system would also automatically extract the most streamlined parts of the system. The service is used to provide speed, so this vulnerability is also triggered.
This vulnerability itself is very simple, just a small patch is required. This patch was written by Zhang Yang in his previous life. After quickly restarting the computer, Zhang Yang directly opened the system's service item, turned off several services in it, and then set the key processes in the system startup item. Only then did Zhang Yang directly open the system that Shao Jianglin had installed. c++.
Seeing that the program started directly, Shao JianglinHis face became extremely ugly. In fact, it had been like this from the beginning. The people watching the excitement also noticed something. Everyone pointed at Zhang Yang and Shao Jianglin and whispered something. This loophole program is not big. , several hundred kb in size, Zhang Yang quickly finished it in just ten minutes. After running the vulnerability program, Zhang Yang directly pressed the restart button.
As the computer screen started up, Zhang Yang quickly ran a program such as QQ. After there were no problems, Zhang Yang stood up, turned around with a smile and asked, "Do you want to try it yourself?"
"No, since you have fixed it, what happened today is my fault and I apologize." Shao Jianglin hesitated for a moment, then gritted his teeth and said quickly, picked up the computer on the table and walked outside quickly. .
"Wait." Zhang Yang shouted quickly.
"What else do you want to do?" Shao Jianglin turned around and asked in anger.
"Nothing, I just corrected it. It's not that I fixed it, I just restored what you did. Under normal circumstances, there is no problem with this thing." Zhang Yang said with a smile, if the system service is not changed and process, this computer will not have any problems, Zhang Yang is right to say so.
Shao Jianglin¡¯s face changed from red to white, and without saying anything, he turned around and walked outside with the boys.
"Pa" "Pa" After Shao Jianglin left, the seven or eight boys surrounding him actually clapped. Zhao Li and others quickly joined in the fun. Zhang Yang was speechless and made himself look like a hero, shrugging his shoulders. , Zhang Yang said to the boys: "The man just said it is right. Lenovo is indeed far behind the international giants, but he is also right. Everyone supports domestic enterprises. What you buy is not buying, so buy Lenovo Bar."
"Okay, no problem. That beauty, the few of us will buy the model you just introduced. Please help us go through the procedures." One of the boys said hello, and then said quickly.
"Ah, okay, come with me." Li Keqing was stunned for a moment, then said quickly with a smile. Zhang Yang ignored the weird looks from Zhao Li and others, turned around and walked to the rest area and sat down.
