After Cobra's inspection, no obvious anomalous data was found, and a specific analysis was needed to find out where the problem was.

"Xiaohu, you can try it!" Cobra gave up the computer to Hu Yifei, and he went aside to do further analysis of some of the detected data.

Hu Yifei walked to the computer, and he didn't rush to take out his tools, but just opened the Zhizhi to see what the mayor was doing at half past eight every day.

Calling up the data for this time period for four consecutive days, Hu Yifei began to do comparative analysis, and soon found a strange phenomenon, during this time period of four days, the mayor had visited the same website.

Hu Yifei hurriedly beckoned Captain Li over, "Captain Li, come and see!" What is this website? ”

Captain Li took a look at it and said, "This is the website of the Organization Department of the Provincial Party Committee!" ”

Hu Yifei said "oh", it turned out to be a serious website, so he continued to check, he turned the Zhi forward, and found that except for Saturday and Zhou, the mayor would basically visit the website of the Organization Department of the Provincial Party Committee every day during this time period, so he asked Captain Li, "The mayor seems to have a habit of visiting this website?" ”

"Do you suspect that the problem lies with the website of the Organization Department of the Provincial Party Committee?" Captain Li asked, his brows immediately locked together, if there is an accident on the website of the Organization Department of the Provincial Party Committee, then it will be a big problem, and he also organized personnel to analyze all the websites involved in the theft of secrets before, and did not find any problems!

"Just wondering, is there any data on other computers? Did you also visit this site during the time when it was stolen? Hu Yifei asked.

"I'll check it out right away!" Captain Li hurriedly took people out of the mayor's office, and the network supervisor had invested most of the technical forces in the mayor's place, and the other computers really hadn't had time to check in detail.

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

"Intrusion detection tools!" Hu Yifei said.

"Are all tools certified for security by the Cyber Supervision Corps?"

Hu Yifei was dumbfounded, shook his head and said, "This is not!" ”

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

Hu Yifei had a headache and said: "Then if this is not the case, I will not move this computer, I will use my own computer, and then access the network of the municipal axe, this will always work, right?" ”

The political axe staff still shook their heads, "This is not good, the network of the municipal axe is strictly forbidden to be accessed by external devices!" ”

Hu Yifei lost his temper, he was invited to do the test, but what if he was not allowed to use the tools he had, he said: "Forget it, let's wait for Captain Li to come back!" ”

Next to him, Cobra said to the man: "The rules are dead, people are alive, Xiaohu is a partner of the Internet Supervision Corps, or Captain Li can ask him to come over to assist in the investigation, you let him check, no problem!" ”

The man did not regress, "People can be trusted, but if his tools are not certified for security, I can't let him use them, in case something goes wrong, don't say that I can't afford this responsibility, even Director Hui's information center can't afford this responsibility!" ”

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

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

The boss was very excited, sat down with Hu Yifei, squatted twice with his buttocks, and then said in a low voice: "This high-end sofa feels good to sit on!" After finishing, he said: "The second master, where do you think the problem is?" ”

Hu Yifei shook his head, "It's hard to say!" ",When it's over, I don't speak.,Sitting there pondering the Yue Zhi just turned out.,The other party should be a master.,He also looked at the computer just now.,The latest anti-virus software and software firewall,There is no alarm.,There is only a record of visiting the website in the Zhi.,And it's a serious website.,I can't see anything abnormal at all.,There are no traces of other programs running on the machine.,As for other problems,I don't have to think about it.,If there is,,It's already been discovered by Captain Li and Cobra.。

"If the problem is really on this website, then by what means?" Hu Yifei sat there and touched his nose, and said in his heart, could it be DNS hijacking?

The role of this DNS is a bit like a map navigation service, we usually have to go somewhere, for example, to the Organization Department of the Provincial Party Committee, we only know a name, but we don't know where it is, so we go to the map of the hundred poisons and enter the words "Organization Department of the Provincial Party Committee", and then the map will immediately report its location, No. 5 Lisi Hutong, Zhangsan Road, and then what is the specific route.

Similarly, to visit the website of the Organization Department of the Provincial Party Committee, after we enter the URL, the DNS began to act at speed, rummaging in their own "map library" to see if there is this website, if so, what is its address, and so on to find the IP address of the website, we naturally opened the website, because the transmission speed of the electronic signal is very fast, the process is very fast, we don't even feel the delay, but in fact, at this moment, the computer has done a lot of work.

This gives others the opportunity to take advantage of it, if someone monitors your DNS query information, and then forges fake information to you, telling you a wrong IP address, then the website you open, it is very unreliable, it is possible that you see the real website is exactly the same, but this website is carefully disguised by others.

"There should be a monitoring system in the network of the municipal axe, if there are other computers monitoring and sending fake DNS information, it will be detected!"

Hu Yifei scratched his head, could it be that he was wrong? Is the problem really not with this website, but with hacking? Then this hacker is too windy, like a white-collar worker, and he still pinches a little bit to go to work every day.

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

When the mayor entered the door and saw the mess of people in his office, he frowned slightly, "That, Mr. Hui, is there a conclusion to the matter?" ”

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

The mayor was a little dissatisfied with the result: "I've always emphasized the importance of information security, but some people just don't do it properly, how about it?" The hackers have bullied the heads of the municipal axes! If you don't pay attention to it, you will suffer! When the mayor said this, he changed his face to stern, "This hacker who dares to steal the secrets of the political axe must be caught, I want to teach everyone in the city a lesson in information security, and at the same time kill the majesty of hackers!" You have to hurry up and pay attention to this! ”

"Don't worry, Mayor, I'll do my best!" Cobra is making promises.

"The matter of the information security standard system cannot be relaxed, and it must be implemented in a planned manner in accordance with the formulated plan." After the mayor finished giving instructions, he turned around and saw Hu Yifei and the boss on the side, and said that this person was a little familiar.

Before he could speak, Hu Yifei spoke first, "Mayor, I'm Figo Safe, come here to assist in the investigation!" ”

The mayor let out an "oh", "Thank you for your hard work!" ”

"It's not hard!" Hu Yifei paused and said with a smile: "I just looked at the Yue Zhi on the computer and found that the mayor has a habit of visiting the website of the Organization Department of the Municipal Party Committee at about half past eight in the morning every day!" ”

The mayor was slightly surprised, "Is there anything wrong with this?" ”

"It's not clear what hackers are trying to do, so it's hard to say! But one thing is for sure, the hacker who invaded must have known about the mayor's habit! Hu Yifei said.

The mayor was not a fool, and immediately understood what he meant, "It seems that this habit of mine has to be changed!" ”

As soon as he finished speaking, Captain Li hurriedly came in, saw the mayor there, and saluted, "Hello mayor!" ”

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

Captain Li had no choice but to get down to business first, and said to Hu Yifei: "I went to check just now, and several other computers are the same, and the time period when the documents were stolen all visited the website of the Organization Department of the Provincial Party Committee, it seems that the matter is a bit serious, and the problem may not only be our Dongyang City!" ”

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

Captain Li was a little embarrassed, "Now the suspicions are all attributed to the website of the Organization Department of the Provincial Party Committee, but it has not yet been determined, and the website of the Organization Department of the Provincial Party Committee needs to be analyzed!" ”

"Analyze it now!" The mayor gave an order, walked to the desk after speaking, picked up the phone, thought about it, and put it down again, this matter can't be in a hurry, in case it stabs the organization department, and there is no problem with the website over there, he will be passive, so he ordered Captain Li again, "Right here, analyze on my computer, I want to watch the analysis results come out!" If this thing is confirmed, it is also a great credit, and it is a timely recovery of losses for the organization.

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

"Xiaohu, have you checked the website, have you found anything?" Captain Li asked.

Hu Yifei shook his head, "I came in a hurry today, and I only brought tools, but my tools have not been certified and are not used!" ”

Captain Li pushed aside a technician from the network supervisor next to him, "You can use our computer!" ”

Hu Yifei took out the USB flash drive again, copied the tool to the computer of the network supervisor, ran one first, and then opened the website of the Organization Department of the Provincial Party Committee, and after a while, he said: "No DNS hijacking was found in the local area network, let me analyze the website again!" ”

After finishing it, he ran another program, and then refreshed the website of the Organization Department of the Provincial Party Committee, and the tool immediately called up, Hu Yifei looked at it, and said: "There is really a problem!" ”

The mayor stepped forward a few times, "What's the problem?" ”

"Malicious code has been downloaded!" Hu Yifei stared at the prompt on the screen, "Strange, the code is written in language Z!" ”
