Captain Li quickly made a material of Hu Yifei's ideas, Cobra's discovery, and the loopholes of the website program, and sent it to the National Internet Emergency Response Team. In the next few minutes, the network supervisors all over the country who were still busy with their work received this material, and after another half an hour, some traces of hacker intrusion were found in various places one after another.

The vulnerabilities exploited by hackers when uploading code are different, but their methods are surprisingly consistent, as Hu Yifei said, a hacker first uploads the code to the server sentence by sentence, and then through the combination, it becomes an attack program that can be executed, after the program is executed, and then open a new backdoor, or carry out other operations, the hacker is coming in step by step, each step is very hidden, and will not touch the monitoring system on the server, which is completely different from the simple invasion in the past.

Hu Yifei and Cobra joined forces to study the data and analyze what the effect of that code was executed, and it was not until it was almost dark that the two came up with an accurate conclusion.

After listening to the conclusion, Captain Li's eyes were dark, and he almost fell down, after the code was executed, there was no backdoor opened at all, and the code directly judged the directory of the website on the server, and then implanted the malicious code on the homepage of the website.

In other words, the hacker did not enter the server at all from the beginning to the end, and it will be very difficult for the network supervisor to use this clue on the server to track the whereabouts of the hacker.

The hacker first took advantage of the vulnerability on the website program to implant the code on the server one by one, and then took advantage of this vulnerability to execute the code remotely, but in this process, the hacker is actually a normal website visitor, he did the first two steps by visiting the website's web page, the server's Zhi, it is difficult to reflect the abnormality, and the website visits so much every day, to find the hacker from the visitor's IP, the difficulty is no less than looking for a needle in a haystack.

"Lao Li!" Cobra went over and helped Captain Li, "Fortunately, things have been figured out, let's slowly screen these IPs, I believe there will always be some findings, you hurry up and report this conclusion, so as not to make everyone move blindly!" ”

Captain Li froze, sighed, and hurriedly called Hei Tian again, "Boss Hei, we have a conclusion here, after that code was executed, the malicious code was directly implanted into the website, and the hacker did not enter the server." ”

Hei Tian was not flustered at all, "This conclusion, Hu Yifei came to it?" ”

"The conclusion was made by Xiaohu and Mr. Hui together, and it won't be wrong!" Captain Li paused, "What do you think we should do now?" ”

"It seems that we have to shift our focus to the servers that are used to receive the stolen files, but we also have to screen the IP of visitors to the website servers and identify a few suspicious IP addresses as soon as possible!" Heitian said.

"I'll arrange for someone to do this right away!" Captain Li was a little frustrated.

"Well, don't be discouraged, hacker intrusions are always unexpected, and it is always difficult to track, you have been in the industry for many years, you should have been mentally prepared for this!" Heitian comforted a few words, "Thank you Hu Yifei and Mr. Hui for me, the two of them have made a lot of effort this time, and when this busy period passes, I will go and thank you in person!" ”

"Okay, I got it!" After Captain Li finished speaking, he hung up the phone, turned back to Cobra and said, "Mr. Hui, you are also tired for a day and a night, I will let someone send you back to rest!" ”

"What are you sending, aren't you all tired of the day!" Cobra waved his hand, "I'll walk with Xiaohu, and we can discuss on the way!" ”

Hu Yifei definitely didn't object, so he and Cobra slowly paced out of the computer room and went to the street, and the two of them found a restaurant casually and went in to eat first.

"Xiaohu, this incident is also a good opportunity for your company!" When Cobra was eating, he didn't forget to give Hu Yifei advice, "At present, in the whole country, there are only two people who can identify the Z language virus, and you have the most research on the Z language, and you should also count your Figo security, whether it is for security or for the development of the company, you should launch a security software for the Z language virus in the shortest possible time!" ”

"I also have this plan, and when I come out in the morning, I am discussing it with Brother Fan!" Hu Yifei nodded, "The programs are all ready-made and ready to be launched at any time!" ”

"That's good!" As Cobra was talking, the phone rang, and when he looked at the number, he said, "Black boss's phone!" After chatting for a few words, he handed the phone to Hu Yifei, "Xiaohu, the black boss has something to tell you!" ”

"Me?" Hu Yifei was a little surprised, stunned for a moment, and then answered the phone, "Boss Hei, hello!" ”

"Xiaohu, thank you, I am grateful for today's incident!" Hei Tian first thanked him on the phone.

"You're welcome, it's just a gesture, if I can help you!" Hu Yifei was polite.

"That's right, I have a question for you!"

Hu Yifei was taken aback, "If the black boss has something, just say it, don't be polite!" ”

"You have a lot of research on the Z language, so I want to ask you to help me analyze it, if you put aside the hacking incident itself, who do you think planned this incident?" Heitian asked.

Hu Yifei pondered for a while and said: "According to my understanding of the Z language, the number of people who can use this technology today will not exceed five, and these people are all American program experts!" ”

"Is there no other possibility?" Heitian asked again.

"This ......" Hu Yifei thought again, "That's ZM, although I don't know if they will have this technology, but they are currently transforming and want to completely bleach, so I think even if ZM knows this technology, they will not be the mastermind behind the scenes." ”

"Okay, thank you!" Hei Tian smiled, "Then I won't disturb you and Mr. Hui to eat, I'll talk to you again when I'm free another day!" ”

"Okay, goodbye Black Boss!" After Hu Yifei finished speaking, he returned the phone to Cobra.

Hanging up the phone, Cobra said: "From the time I entered the industry to the present, this time is the biggest, and there is no specific loss until now, and there may be millions of stolen documents!" ”

"Sooner or later, you can find the mastermind behind the scenes!" Hu Yifei said, continuing to eat, he also saw the power of cyber espionage warfare for the first time.

Hu Yifei returned to the company, the boss was studying the tutorial of network security in front of the computer, did this large amount of income come into the account today, the boss was completely shocked, he didn't expect to make money doing network security, a software sold for millions, it was to pay attention, and the network security will be mixed in the future.

"The second master, have you eaten?" The boss put down the information in his hand, "What, did the hacker find it?" ”

Hu Yifei shook his head, "The hacker didn't enter the server at all, it's hard to check!" ”

"I'll rub!" The boss suddenly jumped, "Is that such a loss for nothing?" That's too much, isn't it? ”

"I'm still investigating, but the clues are relatively small!" Hu Yifei also felt depressed, no matter what, the target of the spy is his own country and his own territory!

The boss muttered for a long time, angry is angry, but he didn't put forward any good suggestions, vented, and most of his anger disappeared, and said: "There is also the matter of the car, I discussed it with Brother Fan, and ordered the Audi A4, the image is okay, and it is magnificent, what do you think?" ”

"Okay, that's it!" Hu Yifei nodded, he had also seen a few of these cars in the community, and he was a little impressed.

"If you have no opinion, then I'll order it tomorrow!" The Boss asked.

"Let's order this!" Hu Yifei nodded, his mind still thinking about the mastermind behind the scenes.

The boss saw that Hu Yifei had no opinion, so he went to check the name of Dongyang's dealer on the Internet.

Back in the room, Hu Yifei turned on the computer, thought about it, and sent an email to the sugar fried chestnuts, "Has ZM made any recent moves?" ”

This made the cold horn bird a little confused, so he replied: "It's been good recently, and several copies of the security plan and cyber attack weapons have been sold!" ”

"Is there anything related to the Z language in the attack weapons?" Hu Yifei asked again.

Only then did the cold bird understand Hu Yifei's true intentions, and said, "Wait, I'll help you check!" ”

After about ten minutes, the cold bird sent a message, "The second master is really like a god, ZM half a month ago, I really sold an attack weapon, which is related to the Z language, and it is customized by a world-class intelligence company!" ”

"Is there a way to get the details of this assault weapon?" Hu Yifei asked again.

"You can try!" Although he is not specifically responsible for ZM's transactions, he is responsible for the overall operation of ZM, and if he wants to check these information, he has full authority.

"Okay, then I'll wait for your news, it would be better to have the information of that intelligence company!"

"I'll try!" The Bird replied, and then asked, "Is something wrong?" ”

"Something happened, I don't know if it's related to zm, so I'm going to ask!"

"Then I'll do it as soon as possible!" The cold bird pondered for a moment and said, "Tomorrow, tomorrow I will definitely figure it out!" ”

"Okay, then I'll wait for your news!" Hu Yifei said a few more polite words, and then went offline, and in the Z language system that he anonymously traded to ZM, there was no mention of today's usage, but ZM is all a group of technical maniacs, and it can't be said that they will never be discovered.

When he got up the next day, Hu Yifei went to watch the news, but coincidentally, the United States released a commercial version of the z language while he was sleeping, which was released by Microsoft, but the entire compilation system was castrated, removing a lot of magical features, compared with the version released by zm, it is much inferior.

In less than half an hour, the national Internet emergency team issued an announcement, announcing that a nationwide theft of confidential documents was discovered, and millions of stolen documents involved in political axes, military, science and technology and other fields of secrets, the hacker used the Z language code, the matter is currently under investigation, but according to the existing clues, the hacker who launched the attack may have come from the United States.

Attached to this announcement is a technical appraisal detailing the process and methods of hacking and stealing, and the most amazing thing is that this appraisal was actually made by Figo Security.
