Six years later, she amazed the world with her three children

After Xie Yiyi sent this message, she kept waiting for Chu Yuran's reply, but maybe Chu Yuran was busy, and she didn't get any reply after waiting for a while, so she opened a document and started typing.

Qin Jianyu, who drove away, did not go home immediately. Instead, he took out his mobile phone and called Ou Mingyang. When Ou Mingyang saw his phone, he immediately picked up the phone: "Hello, second brother."

"Yangyang, is it convenient to talk now?"

"It's convenient. Rourou went to take a shower. I'm reading a book in the study room alone now."

"Then I haven't delayed your studies, have I?" Qin Jianyu asked.

"Of course it won't delay me. I'm not reading a textbook now, but an extracurricular book. It won't affect me." Ou Mingyang asked quickly, "What's the matter, second brother? It's so late. Aren't you coming back today?"

"Go back, but I need to do something before I go back. If it doesn't interfere with your studies, find a reason to come out now. I'll wait for you at the intersection."

Ok?

Ou Mingyang's blood boiled when he heard this, and he quickly agreed: "I know, second brother, I'll be there right away."

After hanging up the phone, Ou Mingyang closed the book and went downstairs. Zhan Sichen and Qin Muyan were walking in the yard.

"Godfather and godmother, I have to go to a classmate's house for something, so I may be back a little late. You don't have to wait for me." Ou Mingyang said.

"Okay, be careful on the road."

"understood."

After agreeing, Ou Mingyang ran out impatiently. When he reached the intersection in one breath, he saw Qin Jianyu's car.

"Second brother." Ou Mingyang asked hurriedly after getting in the car, "Why did you call me out so mysteriously? What's the matter?"

"Of course it's something you're interested in. Don't you want to learn hacking techniques from me? I'll teach you right now."

"Really?" Ou Mingyang was so excited when he heard this, "That's great!"

"The premise is that it must not affect your studies, otherwise I will become a sinner for all eternity."

"Don't worry about my studies, brother. Whether I learn hacking technology or not will not affect my admission to Nancheng University."

Qin Jianyu had no doubt about what he said. Ou Mingyang's personality was exactly like his uncle's. He was the kind of person who was very powerful but never showed off.

They are not aggressive or combative, and are willing to be supporting roles. They are also very loyal and kind. It is very comfortable to get along with such people without any pressure.

"Where are you taking me, brother? A special learning base?"

"No, go to Qin's Hospital."

"Go to Qin's Hospital?" Ou Mingyang really didn't expect this.

"You will know when you go."

Since Qin Jianyu said so, Ou Mingyang didn't ask any more questions.

Afterwards, the two of them went to the hospital. This hospital originally belonged to the Zhan family. When Qin Jianyu came, no one in the hospital would stop him from going wherever he wanted.

Qin Jianyu took Ou Mingyang to the main operating table of the hospital's monitoring equipment. When Ou Mingyang got here, he understood something and asked, "Second brother brought me here for a reason. Is there something wrong with the monitoring of Qin's Hospital?"

"Yangyang is indeed a top student, so smart, but we need to check whether there is really a problem." Qin Jianyu explained, "Controlling the surveillance of a certain area is a very common method of hacker attack.

To make a long story short, there are three common methods of intrusion control monitoring. The first is to scan the protocol and port of the camera to find the camera and imitate the authorized user;

Second, they will exploit known software vulnerabilities in the camera's open source or third-party libraries to launch attacks. Third, they will use command injection attacks to execute external programs or system commands to launch attacks, thereby obtaining data or network resources.

Simply put, the most common method is to exploit system vulnerabilities to launch attacks, and how to check if your surveillance has been hacked, Yangyang, I tell you to do it. "

"it is good."

Then Qin Jianyu stood behind him as a teacher. As he spoke, Ou Mingyang followed his instructions step by step. After he finished, he found out...

"Second brother, does this mean that the surveillance cameras at Qin's Hospital have been hacked?"

"Yes."

"Hackers hacked into the hospital's surveillance system? What did they want to do? Steal patient information?" Ou Mingyang asked in confusion.

Qin Jianyu would not tell him the truth. After all, he was a high school student now and could not let him know these dangerous things.

"I invaded here to teach you, didn't I?"

"Ah?" Ou Mingyang was really surprised. "Second brother, are you so sincere? You want me to have an immersive experience? Is this true?"

Ou Mingyang is much smarter than Yan Meng, the silly boy, and is not easy to fool. Qin Jianyu can only pretend to be serious: "Of course, do you still have to doubt this? What? Is your second brother not nice to you?"

"Of course!"

"With practical facts as the basis, you can learn quickly. Okay, let's get back to the point." Qin Jianyu said, "The hospital's monitoring system can be hacked, which means there is a bug in the system, and I found this bug, so I took advantage of it.

How to avoid this situation? You need to filter the data well and make good use of the whitelist to avoid this attack. This is the job of software developers, but I will teach you and you can do it. "

"Okay, second brother!"

Qin Jianyu looked at the time again. It was getting late. Ou Mingyang hurriedly said, "Brother, I don't have school tomorrow, so I can sleep in. You teach me, teach me quickly!"

Ou Mingyang was really eager to learn, so Qin Jianyu couldn't refuse his kindness. Although he could do it, he still had to contact the software developer and needed his cooperation.

It is not a small project to fully upgrade the software and thoroughly fix the vulnerabilities in the software system, but Ou Mingyang learns quickly.

Qin Jianyu stood aside and watched, then looked up at the camera here. The surveillance equipment had been hacked. If the other party wanted to see, they could see what was happening in the hospital at any time.

Now? Is he watching too?

After working as a hacker for so many years, he has not been asked to do anything else except helping his father with various investigations. It seems that he has met his match.

Nowadays, human traffickers have also started to use high technology. They no longer just randomly arrest people on the street, but illegally hack into various systems to purposefully find the most suitable candidates for buyers.

What Qin Jianyu thought was correct. At this moment, there was a person sitting in front of the computer, watching Qin Jianyu who was being monitored by him, but soon the computer screen went black.

He tried to invade again, but failed, so...

He entered another system, substituted his face for comparison, and then his information appeared.

"Huachen Director Qin Jianyu?"

He is indeed a powerful figure!

"Finally I met my match. Interesting..."
