After cobra checking, no obvious abnormal data was found. To find out where the problem lies, a specific analysis must be done.

"Xiao Hu, come and try it!" Cobra gave the computer to Hu Yifei, and went to the side to further analyze some of the detected data.

Hu Yifei walked to the computer and did not rush to take out his tools. He just opened the log to see what the mayor was doing during the 8:30 every day. The problem was around 8:30, so naturally he had to start from this time period.

After recalling the data for this period of four consecutive days, Hu Yifei began to conduct a comparison and analysis, and soon discovered a strange phenomenon. During this period of four days, the mayor had visited the same website.

Hu Yifei quickly called Captain Li over, "Captain Li, come and take a look! What website is this?"

Captain Li looked at it and said, "This is the website of the Provincial Party Committee Organization Department!"

Hu Yifei said "Oh" and it turned out to be a serious website, so he continued to check it. He turned the log forward and found that except for Saturdays and Sundays, the mayor basically visits the website of the Provincial Party Committee Organization Department during this period every day. So he asked Captain Li again, "The mayor seems to have the habit of visiting this website?"

"Do you suspect the problem lies with the website of the Provincial Party Committee Organization Department?" Captain Li asked, his eyebrows immediately locked together. If something happened to the website of the Provincial Party Committee Organization Department, the problem would be big. Moreover, he had also organized personnel to analyze all the websites involved in the stealing period, but no problems were found!

"I just doubt whether there is any data on other computers? Have you also visited this website during the period of stolen secrets?" Hu Yifei asked.

"I'll go check it right away!" Captain Li quickly brought people out of the mayor's office. The Internet supervisor had previously invested most of his technical strength to the mayor, and the other computers really didn't have time to check it out in detail.

Hu Yifei was about to copy his tools to the mayor's computer. As soon as he took out a USB flash drive, the staff next to him immediately stopped him, "What's there on you?"

"Intrusion detection tool!" Hu Yifei said.

"Are all tools safely certified by the Cyber ​​Supervision Corps?"

Hu Yifei was stunned and shook his head and said, "Nothing!"

"I'm sorry, you can't copy your stuff to this computer. There are various intrusion detection tools installed on the computer, and you can use them."

Hu Yifei had a headache and said, "Why don't you do this? I won't move this computer. I will use my own computer and then connect to the municipal government's network. Is this the head office?"

The government staff still shook their heads, "This is not possible. The municipal government's network strictly prohibits access to external equipment!"

Hu Yifei was no longer angry and was invited to do the test himself, but he didn't let him use the handy tool. Then he said, "Then forget it, let's wait until Captain Li comes back!"

Cobra next to him said to the man: "Rules are dead, people are alive, Xiao Hu is a partner of the Internet Supervision Corps. Otherwise, Captain Li can ask him to come and assist in the investigation, so you can ask him to check it out, there is no problem!"

The man did not regress. "People can trust, but if his tools are not secured, I cannot let him use them. If something goes wrong, don't say I can't bear this responsibility, even Director Hui's information center can't bear this responsibility!"

Hu Yifei was very disgusted with someone who was pressing people with a big hat, so he waved his hand, "Forget it, Teacher Hui, I'd better wait for Captain Li!" After that, he left the computer, went to sit on the sofa, and waited with the boss there.

Cobra had no choice but to continue analyzing his own data.

The boss was very excited and sat down with Hu Yifei, squatted his butt twice, and then whispered: "It feels good to sit on this high-end sofa!" After that, he said: "Second leader, do you think where is the problem?"

Hu Yifei shook his head, "It's hard to say!" He stopped talking after he finished speaking, sitting there thinking about the logs he had just found. The other party should be a master. He also read the computer just now. There was no alarm on the latest antivirus software and software firewall. There was only record of access to the website in the log. It was a serious website. There was no abnormality at all. There was no trace of other programs running on the machine. As for other problems, I didn't have to think about it. If there were any, I would have been discovered by Captain Li and Cobra.

"If the problem really lies in this website, what methods are they used?" Hu Yifei sat there and touched his nose, thinking that it was DNS hijacking?

The function of this dns is a bit like a map navigation service. We usually have to go to a certain place, for example, to the Provincial Party Committee Organization Department. We only know a name, but don’t know where it is. Then enter the Baidu Map and enter the words “Provincial Party Organization Department”, and then the map will immediately report its location, No. 5, Lisi Hutong, Zhangsan Road, and what is the specific route.

Similarly, if we want to visit the website of the Provincial Party Committee Organization Department, after we enter the URL, DNS will start to act quickly, search in our own "map library" to see if there is any website, if so, what is its address. Once we find the IP address of the website, we will naturally open the website, because the electronic signal is transmitted very quickly, and the process is very fast, and we can't even feel the delay, but in this moment, the computer did a lot of work.

This gives others the opportunity to take advantage of it. If someone monitors your DNS query information, then fakes the information to you and tells you an incorrect IP address, then the website you opened will be very unreliable. It is possible that what you see is exactly the same as the real website, but this website is carefully disguised by others.

"The municipal government's network should have a monitoring system. If other computers monitor and send fake DNS information, it will be found!"

Hu Yifei scratched his head. Did he suspect he was wrong? The problem is really not on this website, but on hackers? Then this hacker is too coquettish, like a white-collar worker, and he still comes to work every day.

After waiting for a few minutes, Captain Li did not come back, but waited for the mayor who came back from the meeting.

When the mayor entered the door and saw the messy people in his office, he frowned slightly, "Well, Mr. Hui, is there any conclusion in the matter?"

Cobra quickly put down what he was doing, "I'm still analyzing!"

The mayor was a little dissatisfied with the result: "I have always emphasized the importance of information security, but some people just don't take it seriously. What's wrong? Hackers bullied the city government! If you don't pay attention, you will suffer a loss!" The mayor said this and changed his face to a stern face. "This hacker who dares to steal government secrets must be caught. I want to teach everyone in the city a class on information security, and at the same time kill the majesty of killing hackers! You have to hurry up and pay attention to this matter!"

"Don't worry, mayor, I will do my best!" cobra made a promise.

"We cannot relax the information security standard system. We must implement it in a planned manner according to the formulated plan." After the mayor finished his order, he turned around and saw Hu Yifei and the boss beside him, thinking that this person looked familiar.

Before he could speak, Hu Yifei spoke first, "Mayor, I am Figo safe, come and assist in the investigation!"

The mayor said "Oh", "Thank you for your hard work!"

"Not hard!" Hu Yifei paused and smiled, "I just looked at the logs on the computer and found that the mayor had a habit of visiting the website of the Municipal Party Committee Organization Department at around 8:30 in the morning every day!"

The mayor was a little surprised, "Is there anything wrong with this?"

"It's hard to say if the hacker's specific intrusion methods are not clear now! But one thing is certain, the hacker must also know the mayor's habit!" Hu Yifei said.

The mayor is not a fool, and immediately understood what this sentence means, "It seems that my habit has to be changed!"

As soon as he finished speaking, Captain Li hurried in and saw the mayor, saluting, "Hello mayor!"

The mayor nodded slightly, even if he had said hello.

Captain Li had to do the job first and said to Hu Yifei: "I just checked it, and the same is true for other computers. During the period when the files were stolen, I visited the website of the Provincial Party Committee Organization Department. It seems that the matter is a bit serious. It may not be the only one in Dongyang City that has a problem!"

The mayor understood the power of this and couldn't help but take two steps towards Captain Li, "Captain Li, can you be sure?"

Captain Li was a little embarrassed, "The doubts now come down to the website of the Provincial Party Committee Organization Department, but it has not been confirmed yet. The website of the Provincial Party Committee Organization Department needs to be analyzed!"

"Analyze immediately!" The mayor issued an order. After saying that, he walked to the desk, picked up the phone, thought about it, and put it down again. You can't be anxious. If you hit the Organization Department and there is no problem with the website there, you will be passive. So he ordered Captain Li, "It's here, analyze it on my computer, I want to see the analysis results!" If this matter is done, it will be a great contribution to recover the losses in time for the organization.

Captain Li immediately arranged someone to come and began to conduct a detailed analysis of the website of the Provincial Party Committee Organization Department.

"Xiao Hu, have you checked the website? Have you found out?" Captain Li asked.

Hu Yifei shook his head, "I came in a hurry today and only brought tools, but my tools were not certified and useless!"

Captain Li sent a technician from the Internet Supervisor next to him, "You use our computer!"

Hu Yifei took out the U disk again, copied the tool to the computer of the network monitoring, first ran one, and then opened the website of the Provincial Party Committee Organization Department. After a while, he said: "DNS hijacking was not found in the local area network. I'll analyze the website again!"

After that, he ran another program and then refreshed the website of the Provincial Party Committee Organization Department. The tool immediately started calling out. Hu Yifei looked at it and said, "There is really a problem!"

The mayor stepped forward a few steps, "What's the problem?"
Chapter completed!
