Hu Yifei searched for a night, and finally found the article, which is very long, which first introduces how to prevent information leakage in various confidential networks, and then how to crack these methods, and finally how to further improve and patch these loopholes, which is very comprehensive.

Hu Yifei flipped through it and found that the Jinlong Pharmaceutical Network, which was already impeccable in his eyes, was really vulnerable in this article. The anti-leakage methods introduced in the article are much more advanced than those of Jinlong Pharmaceutical, but there are more than 50 kinds of attack methods cited.

Anything on the computer can be used in the eyes of hackers, from the keyboard indicator, to the interface of the headphones, and even the power supply, which can be indulged by hackers and become the culprit of leaks.

In comparison, Jinlong Pharmaceutical's preventive measures are too backward, and they are only at the level of cameras, data traffic analysis, and external storage. In this article, these are the lowest level of anti-leakage measures.

Hu Yifei was like reading a science fiction novel, his eyes were about to widen a little before he finished reading a technique, and finally it was so big that it couldn't be bigger, and the word that came to his mind the most was "incredible!" ”。

After reading the article, Hu Yifei felt that the computer in front of him was very unreliable, the keyboard was unreliable, the mouse was unreliable, the headset was unreliable, and it was almost impossible to find a reliable one.

"It's horrible!" , Hu Yifei sighed, the original owner of this hard drive is really powerful, probably has reached the point of "no sword in the hand, the sword in the heart, the sword in the heart, silently" in martial arts novels, just like a weird magician, even if he ties his hands and feet, he can still steal information from your computer.

Returning to reality from the whimsical in his mind, Hu Yifei began to plan what kind of means to use to break the monitoring of Jinlong Pharmaceutical, it is one thing to see, and another thing to do, the article is very wonderful, but most of it provides an idea and principle, but there are no specific tools and tools, and he has to find a feasible way.

Hu Yifei read the attack methods in this article from beginning to end, and found that all of them are feasible, but none of them are feasible, and if they are not feasible, it is because they are too bad, and they are not clear about the principles mentioned in other people's articles, and the principles are not clear, let alone what they have done.

"Whoa!" Hu Yifei was crazy for a while, and it seemed that he could only eliminate them one by one and find a feasible one to come out.

…… The eleventh attack method is how to use the buzzer on the computer to steal data. Everyone knows that when the buzzer is turned on, it will make a "drop" sound, and if the computer fails, it will make a sound of different lengths to prompt where the problem is, so that the maintenance personnel can find the crux of the problem. But it's this inconspicuous guy who usually doesn't need it at all, but it's a super leaking weapon.

…… When Hu Yifei saw this, he stopped and focused his attention, he felt that this method seemed to be somewhat feasible.

The next night, the tarantula sent a message, "Second master, you sent me the code, I have already done the analysis for you!" ”

Hu Yifei hurriedly asked, "How is it?" Can you determine who the author is? ”

"It's safe to say that the code is very distinctive!"

"Tell me who it is!" Hu Yifei was very moved, he finally wanted to find out who that kid was, 10 million, Lao Tzu wants to get you back...... And then...... Spend it!

"The author of the code is a Chinese hacker - Coldhorn Bird!"

"Uh......"

Hu Yifei was stupid on the spot, he read it right, is the three words of the cold bird written like this? Rubbing his eyes, to confirm that he was not mistaken, and the tarantula did not make a typo, Hu Yifei began to have a headache, there is only one cold bird among Chinese hackers, but that is obviously his idol, an absolute top master, how could he be involved with a scum like sugar-fried chestnuts?

"You're not wrong?" Hu Yifei asked how he could not accept this conclusion.

"It can't be wrong!" The tarantula replied directly: "Look at the 36th, 69th, and 369th lines of the code, do they have three characters: 'h', 'h', and 'n' respectively, which are the exclusive marks of the cold horn bird, and all his codes will leave these three characters in these three fixed positions!" ”

Hu Yifei hurriedly turned out the code, found the location that the tarantula said, and saw that there were indeed three characters of hhn, which were in the remarks of the code. Hu Yifei had seen these before, but he didn't notice these three characters, they were mixed with other notes, and they looked meaningless, but he didn't expect that this was the exclusive mark of the cold bird!

"Ahhh Hu Yifei had a splitting headache, and the email virus sent to him by sugar-fried chestnuts, why is the author a cold bird, what is going on? Are they friends, are they in a group, or are they just alone?

Hu Yifei thought about it for a long time, thinking that they should not be alone, the cold bird is the number one hacker in China, how can he be idle every day and have nothing to do, chasing after his ass and shouting masters, this is too embarrassing. Sugar-fried chestnuts had said before that he had a lot of friends in the hacker circle, and that should be when he knew the cold bird, and when he asked for code, this kid took the cold bird to deal with it.

"Dog!" Hu Yifei scolded, and the only real clue in his hand was interrupted.

After being depressed for a long time, Hu Yifei sent a message to the tarantula with a one-in-ten thousand hope, "Isn't your teacher looking for sugar-fried chestnuts, so does his hacker have any information about sugar-fried chestnuts?" ”

The tarantula felt very strange and said, "Didn't you say that you have a clue about sugar-fried chestnuts?" ”

Hu Yifei was deflated for a while, and said in his heart, Didn't my clue be destroyed in your hands half a minute ago, "I just want to synthesize the information from the two aspects!" ”

"Nope!" The tarantula replied very simply, "The teacher has been guarding the wolf summit for more than a week, but the sugar-fried chestnuts didn't show up, so I didn't get any clues!" ”

Hu Yifei sighed, it seems that his hope of recovering 10 million is really slim, he is very bored, and he didn't say goodbye to the tarantula, so he turned off the phone and went out, he had to go outside to breathe, otherwise he would be suffocated.

On Saturday, Hu Yifei arrived at Weilan on time, went up to the office to hang up the rest of the IP, and then picked up the notebook that Weilan had assigned to him and went downstairs.

The security guards hurriedly stopped and said, "Brother Hu, where are you going?" ”

"Get out on errands!" Hu Yifei said.

The security guard saw that Hu Yifei didn't understand what he meant, and said: "The company has a rule that it is strictly forbidden to take out the employee's computer out of the company, and if it must be taken out, it must also be signed by the leader of the competent department!" The security guard smiled, "This is to prevent someone from taking confidential information out of the company!" ”

Hu Yifei didn't expect that this Weilan still had simple information security precautions, and said with a smile: "Do you think this network security department has confidential information?" It's really funny, if someone else wants to leak secrets, they won't go out with the computer so blatantly, mobile phone, USB flash drive, which is not more hidden than the computer?

The security guards all laughed, this is the truth, they have played all the computers here, there is no fart shadow, this week is the first time Hu Yifei saw the oily head slippery surface, he gave Hu Yifei an idea, said: "Today is just the weekend, I think the company's monitoring system should also be maintained, isn't it?" He looked at the other security guards.

"Yes, yes!" The security guards all laughed together, nodding their heads as they laughed.

Oilhead Slip took out the walkie-talkie, "Druid, Druid, I'm a bullhead, the monitoring system is faulty, please turn off maintenance temporarily!" over！ ”

A voice came over the intercom, "Roger, over!" ”

"Alright, now you can go!" Oily head smiled and smiled, "What, go early and come back early, brother, I'm so good friends!" ”

"Thanks, I'll be back when I'm done!" Hu Yifei hugged his fist at the security guards, turned around and went out, but in his heart he cursed the sugar-fried chestnuts again, if he had 10 million in hand, he could have a lot of notebooks, and he couldn't use the company, and he owed others favors. He was depressed for a week, his heart had calmed down, and he was not ready to put any effort into tracking, which was too torturous to himself, but at this time it was hot again.

Hu Yifei came to the gate of Jinlong Pharmaceutical, but was stopped by the doorman and did not let him in. Hu Yifei explained for a long time, saying that he had come to check the network system, but the doorman said that he had not received the notification.

"Damn, it's not good to be a teacher!" Hu Yifei walked away a few steps, and he forgot to save Zeng Xuanli's mobile phone number, so he had to call Weilan's security room and ask the security guard to find the book in the office, and then he got Zeng Xuanli's number.

Just as he was about to dial, the door next to him opened, and several people came out of it. Hu Yifei was a little surprised, the first person turned out to be that Feng Yueying, strange, did their company open so soon, did they really want to take over this business of Jinlong Pharmaceutical?

Behind Feng Yueying were Zhang Gong and Liao Gong whom Hu Yifei had seen last time.

Hu Yifei put down his mobile phone and went over to say hello, "Brother Feng, Zhang Gong, Liao Gong, hello!" ”

Feng Yueying saw Hu Yifei at this time, he looked at Hu Yifei's appearance, and was a little suspicious in his heart, didn't Cobra say that Weilan was not going to be involved in Jinlong Pharmaceutical's affairs, but why did this intern run over. However, Feng Yueying still smiled very gentlemanly: "Hehe, hello, what a coincidence, I actually met you here, Xiaohu!" ”

Hu Yifei was even more afraid, he was afraid that he would skip work in private and come here to test the network in the name of the company would be spread by Feng Yueying, so he hurriedly explained: "I'm here to find a friend!" After speaking, he also asked Zhang Gong and Liao Gong, "What, is Zeng Xuanli in it?" ”
