Chapter 100 Expert Hu You

When Zeng Xuanli returned, he gathered Zhang Gonggong Liao and prepared to carry out security reforms on Jinlong Pharmaceutical's network overnight. She took out the document given by Hu Yifei and said, "You can study this document first, and then come up with a specific plan. This is the information I got from experts, mainly targeting those top secret theft methods."

Mr. Zhang and Liao hurriedly took it over. They were now very dirty. As senior industry insiders, they had never figured out how Hu You experts stole files. This morning, they conducted a routine document inspection and found traces of copying of the experimental data. The hackers entered the network they created, which was claimed to be very secure, stolen files, and did not trigger any alarms from the monitoring system. After checking it later, they could not find clues of the hacker's invasion, which made them very embarrassed.

The two of them took it, looked only on the first page, and immediately said with surprise: "Incredible, incredible!"

"What's wrong? Is the document wrong?" Zeng Xuanli asked.

"No!" Zhang Gong shook his head, "The secret stealing method mentioned here is unheard of. I didn't expect that such a method could be thought of!"

Gong Liao nodded, "In the past, I just thought that these methods had feasible theoretical basis, but they were a bit absurd to implement. Now it seems that it is not absurd at all!"

"Is there a solution?" Zeng Xuanli asked again.

"Yes!" Zhang Gong pointed to the bottom of the file, "The solution has been given in the file! Expert, expert!"

The two of them couldn't put it down after picking it up, so they looked down in anger. This came the sixth item. Zhang Gong felt something at this time, "The last time the expert Hu You just sent the file with a buzzer, right?"

Liao Gong also felt the same way and said, "It must be that's it. We all let him cheat. Last time we didn't notice his actions on his phone. Also, he lied to us about the bullshit shadowless god catch, that was just to confuse the situation!"

When Zeng Xuanli heard that the two of them mentioned the buzzer, he hurriedly asked, "Tell me what's going on, how can the buzzer transmit the files?"

Zhang Gong explained: "The principle is very simple. The buzzer can be controlled through programming, which creates conditions for hackers to control it; secondly, the buzzer can emit very high-frequency sounds, even ultrasound waves, and our human ears cannot hear this ultrasound."

"Yes!" Liao Gong nodded, "This file also mentioned that as long as the file format is converted, and then the buzzer is controlled to send it at the frequency of ultrasonic waves. Although our ears cannot hear ultrasonic waves, any ordinary recording device can record it, and then use the conversion tool to restore the recorded audio file to get the original file!"

Zeng Xuanli was stunned. What? Buzzers, ultrasounds, and files can actually be converted into sounds, and sounds can also be converted into texts? All of these exceeded her cognition and made her feel too incredible. It was like a fantasy. She never thought that files could be stolen in this way.

"Well, this method is too hidden!" Zhang Gong looked like he opened his eyes. "Even if various conversations were mixed in during the recording process, these sounds could be filtered and filtered. It is not easy for those who can come up with this method. Not only should they be proficient in the underlying computer, but also proficient in ultrasonic detection."

Gong Liao was also deeply moved, "Actually, if this method is exposed, it is not magical at all. The mobile phones we usually use can still transmit sounds thousands of miles away in an instant, but we get numb when we contact each other every day."

Zhang Gong smiled and said, "It's true! I didn't expect that the expert Hu You could come up with such a solution!"

"He must be unable to think of his brain. Maybe he learned it from some master!" Liao Gong thought of Hu Yifei's shadowless god scratching thirty meters last time, and his teeth were itchy. This kid deliberately took him into the ditch. No wonder he couldn't figure it out after a week.

"What Hu You expert!" Zeng Xuanli raised his eyebrows and said angrily: "I think you are Hu You expert! If you can steal documents in front of you, you can still not guess what the method is. That is your ability! Didn't you say you are a senior expert? Then why didn't you prevent this in advance? Why can't you understand it after a week!"

The two of them immediately shrank their necks. They didn't know what kind of anger Zeng Xuanli was making. She was obviously stomping Hu Yifei every day, but now she couldn't say anything!

"Look!" Liao Gong was smarter and quickly changed the topic: "The following is about how to avoid data monitoring!"

The two continued to study the documents, but Zeng Xuanli couldn't calm down for a long time. She went to apologize to Hu Yifei today, just for Jinlong Pharmaceutical, not sincere. Even so, she felt that she had suffered a great grievance and was reluctant. It was not until Hu Yifei took out the documents that she sincerely said thank you, but that thank you was also for Jinlong Pharmaceutical.

Zeng Xuanli didn't think he should apologize to Hu Yifei. He sold his QQ and he loved to show off. This could be considered his fault.

The two people in front of him were all top security experts in China. Jinlong Pharmaceutical also took a lot of effort to dig them back then. However, Hu Yifei's documents made the two top security experts exclaim incredible, which shows how technical content and value of the document are. In the technology industry, there are many things that cannot be exchanged for no amount of money. But Hu Yifei believed in the documents of Chengpiao Astronomy Network Security.

Zeng Xuanli carefully examined his usual words and behaviors for the first time, and recalled all the battles he had encountered since he met Hu Yifei.

Hu Yifei was the first person who could cheat his QQ number and dared to sell it when he turned around. This made him very angry and felt that his IQ and charm were humiliated. He went to the University of Science and Technology to find him, but it caused a storm. Hu Yifei was punished three times and was almost expelled from the school. In the first round, no one took advantage.

Then, someone hyped this matter on the Internet. Hu Yifei spent money to find someone to shock these people, and then calmed down the hype. He should be selfless at this time, not for him, but for himself. Then, he beat him up and humiliated him with the money. In the second round, he won the whole victory.

Hu Yifei was looking for hackers for himself at that time, but every time he saw him in the future, he always used this to threaten him. The more he retreated, the more he pressed forward step by step, which led to his anger. His anger seemed to be just to prove that his previous retreat was not incompetence, but because he was unwilling to care.

Zeng Xuanli sighed quietly. He really misread Hu Yifei. The guy who seemed ignorant, cunning, vulgar, greedy and lustful, had his unique cuteness and innocence in his heart. He always thought he was right, but he didn't expect that this was the biggest mistake in itself.

The next day, Hu Yifei went to Weilan to work again as usual, and this time the fourth brother followed him. After getting off the car, the fourth brother exclaimed, not for Weilan, but for the big signs of Microsoft, Google, and Oracle opposite Weilan.

"The second head, your workplace is really good!" The fourth brother was very envious, "You can meet these elites in the IT industry every day!"

Hu Yifei nodded and smiled bitterly. On the weekend, I was the only one here to work. Those who met him were all the best people in the security industry.

When he arrived at the office, he hung up the IP for scanning. Hu Yifei led the fourth brother downstairs and prepared to go to the electronic city to buy hard drives. He skipped work continuously and was used to it. He was not as afraid as he had just arrived. Now he could flash people at any time and he didn't have to say hello to anyone.

This made Lao Si even more envious. In such a huge building, the security guards all listened to Hu Yifei. Hu Yifei came whenever he wanted, and left when he wanted. Where can I find such a good job?

"Second leader, do you still need people here?" The fourth brother smiled flatteringly, almost treating Hu Yifei as Weilan's chairman.

"I'll ask!" Hu Yifei said, and asked the security guard at the door, "Do we still hire security guards in our building?"

The security guard was stunned, then smiled and said, "No more! Why, your brother is going to be a security guard?"

The fourth brother rolled his eyes immediately, "Damn, I won't be a security guard."

Hu Yifei spread his hands and said, "It's not that I don't help you, it's because I'm here, so I can only talk to the security guys. I can't see any other people in the company."

The security guard said, "On the weekend, we are the only security guards to go to work!"

The fourth brother realized that the intern in the second in charge was almost treated as a security guard, and he felt sad. When he graduated, he might not even be a security guard.

The two of them spent a morning shopping and finally bought a hard drive and two pirated discs. After lunch, they ran to Weilan again. Hu Yifei had to harvest the scan reports of those IPs before retreating. There was no way, and he had to be a monk for one day to hit the bell.

When I reached the sixth floor, I saw that the gate of the Cybersecurity Department was open and the security guard was standing at the door and walking back and forth.

Hu Yifei's heart skipped a beat. Damn, it must be someone who came. I'm afraid I can't hide the fact that he skipped work in the morning. It's strange that the security guard downstairs didn't say anything just now, and he was ready to make a statement.

When the security guard saw Hu Yifei, he looked happy, pointed inside, and signaled Hu Yifei to go in quickly.

"The mysterious secret!" The fourth brother scratched his head and walked in directly.

Hu Yifei was about to pull the fourth brother, but he didn't expect the fourth brother to jump in first. He felt bad, so he had to follow in quickly, but found a person sitting inside, Feng Yueying.

"Hello, Brother Feng!" Hu Yifei quickly greeted him, and suddenly realized in his heart. No wonder the security guard was shaking at the door. It turned out that there was an outsider coming. There was no one in the company, so the security guards had to watch. Another thing was that the security guards were anxious to play games.
