Chapter 152 System Vulnerabilities (2nd update on 3rd)

Mu Fei waited for a long time but didn't wait for Bingguang and Sasha to enter the game. While he was confused, he received Bingguang's text message, "We were attacked, and we won't go online..."

The group of people came as soon as they said that, Mu Fei thought to himself and replied to him a message, "What should I do? Can't I defend myself?"

"No, they probably have mastered a loophole. If there is relevant information, Sasha and I are now like a blind man fighting with a normal person. We don't know how the other party fights. We can only bear it and hide. Oh, I'm so holding our breath!" Bingguang replied, Mu Fei seemed to be able to feel his depression at this time.

However, Mu Fei's computer skills are not as good as him, so he can't help, so he can only persuade him. While replying to the text message, Xu Xiaomeng finally finished the housework and quietly pushed Mu Fei away and slipped in, covering Mu Fei's eyes, "Guess who I am?"

There are only two people in the room, who else can it be? Mu Fei is busy and patted the little loli on the head, "Little Meng, don't make trouble now, I will play with you after my brother finishes his work..."

"Oh!" Xu Xiaomeng responded obediently, sat on the carpet, leaning against Mu Fei's legs, stretching her head to see what Mu Fei was playing. Although Mu Fei allowed her to use the computer, the little guy seemed to be more interested in TV than the computer. He watched bubble dramas and other programs all day long, but he had never touched the computer.

Mu Fei replied to Bingguang's message and pointed at the computer, "Xiao Meng, do you want to play?"

Xu Xiaomeng shook her head, "Xiaomeng doesn't, and she looks so dizzy..."

When Mu Fei heard this, he felt energetic. When the little guy mentioned playing with her, she immediately accepted it, but she didn't play with this cs and said she was dizzy. Could it be that she is the legendary 3D vertigo?

"It's okay, you can't play, I can teach you!" Mu Fei picked up Xu Xiaomeng, let her sit on his lap, holding her little hand and teaching her how to operate, "The keyboard controls movement, mouse attacks, just like this..."

Xu Xiaomeng learned how to operate it very quickly, but when she was playing by herself, there were many problems. Under the control of the little loli, the scenery on the screen was shaking irregularly, looking at the sky and the ground, and the road she walked became irregular curves. I don’t know what she was so low that she was doing.

After persisting for three minutes and being beaten to death n times, the little loli finally tilted her head and leaned against Mu Fei, "Brother, Xiao Meng is not good anymore, she is so dizzy, she wants to vomit..."

In fact, Mu Fei just wanted to find a game that could beat her safely. He could bully her when playing with her in the future. But when he saw Xu Xiaomeng's pretty face turned a little white, he felt unbearable, "Forget it, forget it, if you don't like to play, I won't play with you in the future..."

Mu Fei held Xu Xiaomeng's petite and soft body in his arms, letting her lean against her chest, and gently pressed the acupoints on her head, trying to make her feel better.

"Brother, keep your word..." the little loli said, stretching out her little finger.

"Count the number, when did your brother deceive you? Did you?" After Mu Fei hooked her up, she smiled with satisfaction.

Mu Fei sat with her for a while, and the phone rang again. Mu Fei didn't know what was going on. He didn't usually have a phone call, but he was busy today. He picked it up and saw that it was another strange number.

Mu Fei pressed the answer button, "Hey, hello, who?"

"Fei, Brother Fei?" A crisp girl's voice came from the other side of the phone, which probably sounded much bigger than Xu Xiaomeng.

"Are you... Sasha?" Mu Fei asked tentatively.

"Yeah!!" Tiantian also answered from there, and the sound seemed to be happy because Mu Fei recognized her. The person who called was the little sister of the "Three Guys", Sasha. Her name was Mu Fei "Brother Fei" because Mu Fei's online name was just one word - Fei.

"I didn't expect the little princess to call me, haha, tell me, Sasha, what's the matter?" Mu Fei had a good impression of the little sister he met online, and his tone was calm and authentic.

"Brother Fei, Xiaoguang and I are attacked again. We can't get into the game anymore. Let me tell you..." Sasha's voice came from the phone.

It seems that Sasha doesn't know that she and Bingguang have passed the message, "Oh, Xiaoguang told me, it's okay, let's play next time, how are you doing? Is the situation serious?"

"It's very troublesome. They should have used some loophole to invade our computers, but now we don't know what kind of loophole is, and we can't even start to prevent it..." Sasha's voice sounds very nice, just like what is said in martial arts novels, like the sound of wind chimes blowing in the spring breeze, the singing of the swallows, the sound of the orioles is crisp and pleasant. Mu Fei has heard her voice but never seen her appearance. However, with such a beautiful voice, she probably should be a lively and cheerful little girl, right?

"What's the main thing about you being attacked? By the way, don't you check information online or something? Are you and Xiaoguang members of the same hacker gang? Do they don't know?" Mu Fei asked.

"Brother Fei, that's a hacker alliance. Those who do bad things are called gangs, okay?" Mu Fei seemed to be able to guess that Sasha must be rolling her eyes there.

"Okay, it's my mistake, it's the alliance, the alliance..." Mu Fei explained.

"Hehe, I'll forgive you for this time. The abnormality of our computers is mainly because the network speed and machine are slow, and there is always an unknown and error dialog box. And..." Sasha knew that Mu Fei was at the average level of computers, but she still told Mu Fei about the abnormality of their machine. "That's all the abnormal situations. Xiaoguang and I have checked the information, and my friend has asked. Someone has heard of such a new loophole, but no one knows the specific situation..."

"Oh, so that's it. If I had a little bit of computer experience, I could fight side by side with you. Now, you are the only one who works hard on your own..."

"Hey, Brother Fei is okay. Anyway, we are just looking for you to go online. Since we know your phone number, it doesn't matter whether we can go online. Let those bad guys go..." Sasha's voice on the phone sounded very interesting, and she didn't seem to be depressed about being attacked at all.

When Mu Fei saw that they had nothing to do, he was relieved. The long-distance phone bill was very expensive. Mu Fei chatted with her for a few casual words and hung up the phone. When Sasha's tone seemed to be a little reluctant, Mu Fei discovered that he seemed to have the potential to be a nurseryman, such as Xu Xiaomeng, Mi Beibei, and Sasha. These underage girls all like to stick to him.

During the process of Mu Fei's call, Xu Xiaomeng kept sticking to Mu Fei's arms, listening obediently as he listened to him. When he hung up the phone, he spoke, "Brother, the one that the young lady said seemed to be No. 103573 of the forklift system, nicknamed Dairy Cow..."

"Oh?" Mu Fei suddenly felt enlightened when he heard this, "Xiao Meng, do you know what Sasha is talking about?"

Xu Xiaomeng had already walked out of the dizziness just now. When she heard Mu Fei's words, she raised her neck and smiled proudly on her face, as if she was showing off. "Of course Xiaomeng knows it, brother, you underestimate Xiaomeng too much..."

Mu Fei thought that the little loli had all kinds of information three hundred years later, and it seemed that it was not particularly incredible to know this small system vulnerability.

"Okay, brother knows Xiao Meng's life is bad, okay, hurry up and tell me Sasha what's going on..."

Hearing Mu Fei's words, Xu Xiaomeng leaned into his arms in a comfortable position and explained in her tender voice.

From her words, Mu Fei learned about the loophole. The netizen named Dai Niu. He was discovered by a hacker in early 2011, but the news was not spread everywhere. Mu Fei didn't understand some terms. In short, this loophole is very hidden and very harmful. The immersed computer not only have information and no guarantees, but also may be stolen from various game accounts, online bank accounts, etc. "At that time", many netizens suffered huge losses, but they didn't even know what they got. Later, the loophole was only taken at the end of 2012. Xiaoruan, a company, the fork-budget system, released relevant patches to stop this network chaos. However, netizens who suffered the losses had no one to manage their finances and could only bear it silently.

This is the information about the future, and Mu Fei only knew this information. Otherwise, he would not know anything now.

"Well, do you know if this vulnerability has any manual defense methods besides patching?" Mu Fei asked.

"Yes! Actually, this vulnerability is not difficult to prevent. It is caused by conflicts in some system service projects. Just change the opening situation of certain services. First, this way, and then that way..."

Xu Xiaomeng counted on her white and slender fingers and said while counting.

Mu Fei patted her arm, "Xiao Meng, don't just say it, you can try it too..."

"Oh!" Xu Xiaomeng responded, using the computer to explain to Mu Fei while operating. In less than five minutes, the demonstration was completed.

"So that's it, so that's it." Mu Fei thought in his heart, but suddenly felt aroused. Since Xu Xiaomeng knew about this loophole, she must also know other loopholes. If this is true, then this is also a resource.

"Xiao Meng, you have a fork-blocking system, and other important loopholes in the future, right?..." Mu Fei asked anxiously, with expectation in his eyes.

Xu Xiaomeng's words did not disappoint Mu Fei. She slid her head and said, "Of course there is..."

"That's great..." Mu Fei was so excited that he couldn't stop. He lifted Xu Xiaomeng up and circled around for two times before he put her down.

"You have made contributions. What do you want? Tell me, I will definitely satisfy you..." Mu Fei pinched Xu Xiaomeng's little Qiong's nose and said dotingly, "Xiaomeng, you can rest for a while or play for a while, I'll call."

Mu Fei said, pulling out Sasha's phone number. After a moment, Sasha's crisp voice came, "Hey, Brother Fei?"

"It's me, Sasha, you told me that you have more than one computer at home, right? Does that one have access to the Internet?"

"Yes, there is one downstairs, and I have a laptop," Sasha said.

Mu Fei thought to himself, it seems that Xiao Shasha is still a child from a wealthy family. Not to mention so many computers, the houses at home are all on two floors.

"Sasha, use another computer, don't use your own QQ. Apply for a new one. Add my friend. I'll send you some information..."

"Ah? Oh, OK, I'll do it now, but Brother Fei, what did you send me?"

"Hehe, I won't tell you!! But you will definitely like it. Reinstall your machine and apply the full patches. Then follow the information I gave you. At your level, you will understand it at a glance..." Mu Fei kept it silent.

After Sasha talked to Mu Fei with the newly applied QQ, Mu Fei sent her the defense method for the "cow" loophole.

Half an hour later, Shasha's head was shining with colorful light in Mu Fei's QQ.

Before Mu Fei was finished typing, Sasha's head shaking violently. When she clicked on it, she saw a bright smile, "Brother Fei, hello, that method is really useful. Their attacks are not effective, and we are no longer afraid of using them..."
