Chapter 251 Network Security

"Well, I know the whole story, but why did you hide it from your parents? It makes them anxious." Wu Bin asked with some confusion.

"Oh, you don't know!" Pei Jiamin said, lowering her voice a little, "Don't think my mother is usually very strict with me, but she actually loves me. If I tell her that I am under such great psychological pressure, she will definitely not Promise to let me continue studying medicine.”

Wu Bin: "Then you can't keep hiding it."

"I don't plan to hide it all the time. I just want to exercise secretly until I can watch those bloody movies and eat at the same time." After finishing speaking, Pei Jiamin added: "I actually kept telling them that I was fine, but they refused to believe me. .”

"Nonsense..." Wu Bin looked at Pei Jiamin and said, "When you first poked your head out, I almost didn't dare to recognize you. Your face was so thin and sunken."

Speaking of this, Wu Bin suddenly added, "You couldn't eat just because you watched those bloody movies, right? Then your face became worse and worse, and you became thinner and thinner?"

"It seems...that...probably." Pei Jiamin shrank back, "Yes."

Okay, the case is solved.

"Then why... forget it, no more questions." Wu Bin shook his head, "Then what is the effect of your special training?"

"Well...actually...it's... quite effective...?"

"to be honest."

"Well..." Pei Jiamin pouted, "Actually, I closed my eyes when most of the bloody scenes popped up."

"Then it scares you so much that you can't even eat anything???"

"Because the plot is also very scary!" Pei Jiamin immediately expressed dissatisfaction.

"Okay, you win." Wu Bin patted his forehead, "Then how long do you have to train until you are strong enough?"

"I've dared to see broken arms and legs now, so I should be able to adapt to it soon."

"Wow, you are awesome, I give you a thumbs up." Wu Bin said and gave Pei Jiamin a thumbs up.

"You promised not to laugh at me!" After saying this, Pei Jiamin picked up the pillow and threw it towards Wu Bin.

"Didn't I give you a like? I'm not laughing at you." Wu Bin, who caught the pillow with one hand, expressed his injustice.

"You are obviously just mocking me!"

"Okay, okay, my fault, but you're not good enough if you keep practicing like this. Even if you can really watch bloody movies, it doesn't mean you can dissect corpses yourself, right?"

"I'm going step by step," Pei Jiamin said, stretching out her hand towards Wu Bin, "Give me back the pillow."

"Here." Wu Bin stood up and handed the pillow to Pei Jiamin. When she caught it, Wu Bin suddenly asked, "Have you never thought about giving up studying medicine?"

"No." Pei Jiamin shook her head firmly, "I am willing to overcome fear for my ideals."

Wu Bin smiled slightly after hearing this: "Okay, then I'll help you too."

"Um...huh?" Pei Jiamin looked up at Wu Bin in surprise, "How do you want to help me?"

"I haven't thought about it yet, but it should be better than your current plan."

Although Pei Jiamin was a little unconvinced, looking at Wu Bin's serious expression, she still compromised and said, "Don't scare me on purpose..."

"Don't worry, I'm not that bored."

Then after a period of confused silence, Pei Jiamin suddenly said, "Now it's your turn to tell me how you hacked into my computer."

"Oh, okay." Wu Bin nodded, "Let me ask you a question first. Do you think the various anti-virus software on your computer are particularly safe now?"

"Yes..." Pei Jiamin recalled, "Apart from the recent Bitcoin incident, the thing that impressed me most was the panda burning incense I heard about when I was a kid, right?"

"Well, in fact, the author of the Panda Burning Incense virus has a strong purpose of showing off his skills. If he really wanted to steal your things, how could he blatantly change the icons of all your files?"

"It makes sense..." Pei Jiamin nodded.

"So to be precise, a large-scale virus infection with dazzling skills such as panda burning incense has never appeared again. Of course, the producer's level is indeed very high. I heard that he was later recruited by Gouchang."

"So, other viruses have appeared after pandas burned incense?"

"Of course." Wu Bin nodded, "It's just that most of the network viruses that appeared later came with profit threats, and they targeted institutions and companies with high blackmail value."

"For example, WannaCry, Petya, Bad Rabbit, etc., although most ordinary people have never heard of them, the actual harm they cause is far greater than that of pandas burning incense."

Hearing this, Pei Jiamin interrupted: "So you mean my computer is also infected?"

"Oh, no, I wanted to tell a story about hackers using the MS08-067 vulnerability in Microsoft systems to infect over ten million computers around the world. Especially in our country, due to the extremely high popularity of pirated XP at that time, most pirated users were trying to To prevent a black screen from Microsoft, I turned off the system’s automatic update function.”

"As for virus infections, in most cases, the lower the version, the easier it is to get infected, so our country could be said to be the hardest hit area at that time."

"What happened next?" Pei Jiamin asked curiously.

"Later, this vulnerability gave rise to a virus called Gray Pigeon, which has a very powerful effect in forcing remote control of other people's computers. I also studied it a little and improved it a little. If you want to learn, I can teach you. .”

After hearing this, Pei Jiamin shook her head quickly. She knew very well what a pitfall Wu Bin would be if he did a little research. "Then can you also shuttle through various servers like the hackers in the movie?"

"Theoretically it's possible, but in fact it's difficult for me to check your QQ number now. If you hadn't set up automatic login on QQ, I would have really lost my brain."

"Why? Is it difficult to crack the password? I remember that people often had their QQ accounts hacked in the past?" Pei Jiamin was a little confused.

"You said it was before." Wu Bin opened his notebook and took out a few articles from his favorites and continued.

"When I was browsing the programming forum, several big guys told me that 11 years ago, the newsstands were still selling middle-class books like "Hacker X-Files", "Ultimate Hacker" and "Non-Security Hacker's Manual" Magazines that were huge hits, but they also really helped grow a generation of cybersecurity enthusiasts.”

"Even in order to increase sales, these magazines have set up a special section to teach you how to steal QQ accounts, make phishing software and buy red diamonds, which is an illegal business."

"What's wrong with that person now?"

"Because Goose Farm is rich now. Among the people who cheated and hacked accounts back then, the top ones have been recruited. The remaining guys can't do anything against them, so they naturally disbanded."

"So now, it is relatively easy to steal a wifi password, but if you want to steal a QQ password? Then you have to face the entire Goose Farm, or to be precise, the hacker community in Goose Farm... Oh no , they should now be called the strongest network security administrators."
