Chapter 218 Who is it

Captain Li quickly made a material with Hu Yifei's ideas, cobra's discovery, and website program loopholes, and sent it to the national Internet emergency team. In the following few minutes, the Internet surveillance monitors, who were still busy all over the country, received the material. In another half an hour, some traces of hackers 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 combines it to form an executable attack program. After the program is executed, a new backdoor or performs other operations are opened. The hacker comes in step by step. Each step is very hidden and will not touch the monitoring system on the server. This is completely different from the previous simple intrusion.

Hu Yifei and Cobra joined forces to study the data and analyze what the code will do after it is executed. It was not until dark that the two of them came up with an accurate conclusion.

After hearing the conclusion, Captain Li's eyes went dark and almost fell. After the code was executed, no backdoor was opened at all. The code directly judged the directory of the website on the server, and then implanted the malicious code into the homepage of the website.

In other words, hackers have not entered this server from beginning to end. It will become very difficult for network monitoring to use these clues on the server to track the whereabouts of hackers.

The hacker first exploited the vulnerability in the website program to implant the code on the server one by one, and then used the vulnerability to execute the code remotely. However, in this process, the hacker is actually a normal website visitor. He did the previous two steps by visiting the website's web page. It is difficult for the server's log to reflect the abnormalities. Moreover, the website has so many visits every day, and it is difficult to find hackers from the visitors' IPs.

"Old Li!" Cobra went over to support Captain Li, "Fortunately, the matter has been figured out. We will slowly screen these IPs. I believe there will always be some discoveries. You should report this conclusion quickly so that everyone will not be blindly moved!"

Captain Li calmed down, sighed, and quickly called Hei Tian again, "Boss Hei, we have a conclusion here. After that code was executed, we directly implanted malicious code on the website, and the hacker did not enter the server."

Hei Tian was not panicked at all, "Was Hu Yifei reached this conclusion?"

"The conclusion was made by Xiao Hu and Mr. Hui together, so it would be impossible to be wrong!" Captain Li paused, "What do you think you should do now?"

"It seems that we have to shift the focus of our work to those servers used to receive stolen files, but the IP screening of visitors to the website server must also be carried out to determine several suspected IP addresses as soon as possible!" Hei Tian said.

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

"Okay, don't be discouraged. Hackers' invasion is always unexpected, and it is always difficult to track it. You have been in the industry for many years and should have been mentally prepared!" Hei Tian comforted him, "Thank you Hu Yifei and Mr. Hui for me. This time they both put a lot of effort into it. When this busy period is over, I will thank you in person!"

"Okay, I understand!" Captain Li hung up the phone and turned to Cobra, "Mr. Hui, you are tired for a day and a night, I'll send you back to rest!"

"What are you giving me? Are you tired all day long?" Cobra waved his hand, "I'm going with Xiao Hu, and I can discuss it on the way!"

Hu Yifei must have no objection, so he walked out of the computer room with Cobra and went to the street. The two of them found a restaurant and went in to have dinner first.

"Xiao Hu, this incident is also a good opportunity for your company!" When cobra was having a meal, he did not forget to give Hu Yifei advice. "At present, the only ones who can recognize the Z language viruses nationwide are your Figo Security. The one who is most researched on the Z language must also be your Figo Security. Whether it is for the sake of safety or the company's development, you should launch a security software for the Z language virus in the shortest time!"

"I also have this plan. When I came out in the morning, I was discussing with Brother Fan!" Hu Yifei nodded, "The programs are ready-made and can be launched at any time!"

"That's good!" Cobra was just talking, and the phone rang. He looked at the number and said, "Boss Black Boss' phone number!" After that, he answered and chatted for a few words, and handed the phone to Hu Yifei, "Xiao Hu, Boss Black Boss has something to tell you!"

"Me?" Hu Yifei was a little surprised and was stunned for a moment before answering the phone, "Hello, boss black!"

"Xiao Hu, thank you. Thank you for yours today!" Hei Tian first thanked him on the phone.

"You're welcome, it's just a simple task. Just help you!" Hu Yifei was polite.

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

Hu Yifei was shocked, "If you have something wrong with the black boss, just say it, don't be polite!"

"You have a good study of z language, so I would like to ask you to help me analyze it. If you put aside the hacking incident itself, who do you think the incident will be planned?" Hei Tian asked.

Hu Yifei pondered for a while and said, "Based on my understanding of z language, there will be no more than five people with this technology today. These people are all American program experts!"

"Is there no other possibility?" Hei Tian asked again.

"This..." Hu Yifei thought about it again, "That's zm. Although it's not clear whether they will have this kind of technology, they are currently transforming and wanting to completely bleach them. So I think even if zm has this kind of technology, they will not be the behind-the-scenes planner."

"Okay, thank you!" Heitian smiled, "Then I won't disturb you and Mr. Hui's meal. I'll talk to you again if you have time another day!"

"Okay, goodbye to the black boss!" Hu Yifei returned the phone to cobra after he said that.

After hanging up the phone, cobra said, "Since I entered the industry, this time, I have not counted the specific losses until now. There may be millions of stolen documents!"

"Sooner or later, we will find the mastermind behind the scenes!" Hu Yifei said, continuing to eat, which was the first time he had seen the power of cyber spy war.

Hu Yifei returned to the company and the boss was studying the tutorial on network security in front of the computer. Did this large amount of income make a complete shock to the boss. He didn't expect that he would make money in network security so much that he sold millions of software. So he made up his mind and would get involved in network security in the future.

"Second leader, have you eaten?" The boss put down the information in his hand, "What, have the hackers found it?"

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

"Damn it!" The boss suddenly furious, "Is that a loss so in vain? This is too cowardly!"

"We are still investigating, but the clues are relatively small!" Hu Yifei also felt frustrated. No matter what, the target of the spy's attack was his own country and his territory!

The boss mumbled for a long time, and was angry, but he didn't make any good suggestions. After venting, he was mostly relieved and said, "There is also the matter of the car. Brother Fan and I discussed it and ordered the Audi A4. The image is OK and grand. What do you think?"

"Okay, just this!" Hu Yifei nodded. He had seen several cars in the community and had some impression.

"If you have no objection, I will go and book tomorrow!" asked the boss.

"Just order this!" Hu Yifei nodded, still thinking about the mastermind behind the scenes.

Seeing that Hu Yifei had no objection, the boss went online to check the name of Dongyang's dealer.

Back in the room, Hu Yifei turned on the computer and thought about it. He sent an email to Candy Fried Chestnuts, "Have ZM done anything recently?"

This made Hanhaobird ask a little confused, and replied: "It's good recently. Several copies of security solutions and cyber attack weapons have been sold!"

"Is there any attack weapon related to the z language?" Hu Yifei asked again.

Only then did the Han Bird understand Hu Yifei's true intention and said, "Wait, I'll check it for you!"

After about ten minutes, Hanhaoniao sent a message, "The second leader is really amazing. Zm half a month ago, he really sold an attack weapon. It is related to the z language and is customized by a world-class intelligence company!"

"Is there any way to get detailed information about this attack weapon?" Hu Yifei asked again.

"You can try it!" Hanhaoniao is now full of confidence. Although he is not specifically responsible for zm transactions, he is responsible for the entire operation of zm. If you want to check these information, you have full authority.

"Okay, then I'll wait for your news. It would be even better if I could have the information from that intelligence company!"

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

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

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

"Okay, then I'll wait for your news!" Hu Yifei said a few more politely and then stepped down. The z language system he traded to zm anonymously did not mention the usage today, but zm is all a group of technical madmen, and it cannot be said that they will never find it.

When he got up the next day, Hu Yifei went to read the news. Coincidentally, the United States released a commercial version of the z language during his sleep, which was released by Microsoft. However, the entire compilation system was castrated and removed many magical functions. It was much worse than the version released by zm.

Within half an hour, the National Internet Emergency Team issued an announcement announcing that theft of confidential documents was found nationwide, with millions of stolen documents involving confidential documents in many fields such as government, military, and technology. The hacker used the z language code when attacking. The matter is currently under investigation, but based on existing clues, the hacker who launched the attack may have come from the United States.
