When Chi Ming returned to the Criminal Division, he saw Director Ba Fei, Wu Long, and Murong Fei all waiting for him in his laboratory. Pen % fun % Pavilion www.biquge.info

Chi Ming felt a little pressured, but he still forced out a few words: "Hello everyone." ”

Murong Fei stood aside and didn't speak, and when Director Ba Fei saw Chi Ming coming back, he opened his mouth first: "Chi Ming, the murderer has been rampant to the point of no return, this time I posted the threatening message on Weibo, which will inevitably cause panic in the society, and now I need you to track the murderer's IP address to help the investigation determine the location." ”

In front of Director Ba Fei, Chi Ming looked very low-key, and he said: "Director Ba, as long as the system in my hand is authorized by Captain Wulong, I can give it a try, and I should be able to find out the IP address of the other party." ”

Wu Long nodded and said, "You can use it, I have completed the legal procedures, when you log in, the system will ask you to provide a temporary key, and I have downloaded this key from the relevant departments." ”

Wu Long handed Chi Ming a USB flash drive, and then said: "The key is in this USB disk, you plug it into the USB port of the computer, and when the system asks for the key, it will be automatically read." ”

Chi Ming took the USB flash drive, plugged it into the computer, and then clicked to open the system, the system prompted that the key was being verified, and after a while, the verification was passed, and the system appeared a query interface.

Chi Ming typed the words "Evildoer Terminator" into his username and clicked "Query", and the system quickly listed the blogger's visit history.

Chi Ming took a closer look, he found that this blogger did not have many access records, from the creation of the account not long ago, to the publication of the latest Weibo, a total of more than a dozen times, he noticed the IP address, and found that the countries displayed by those IP addresses were all "United States", "RB This made Chi Ming stupid all of a sudden, how could the murderer be in the United States or RB, the case that happened last night, why didn't he leave the country to the United States so quickly today.

He studied the IP addresses carefully, and found that they seemed familiar, and the IP ranges of these addresses seemed to be common in some proxy servers.

Thinking of this, he scolded his mother in his heart, he said: "Captain Wulong, things are a little wrong, the murderer used a proxy server, this identification system cannot accurately locate the IP address of the other party, what we see is the IP address of the proxy server, and these proxy servers are placed abroad, we can't get the original IP address at all." ”

Wu Long was very disappointed, if he could locate the murderer's IP address, maybe he could analyze the real location of the murderer, but now Chi Ming said that the road had been blocked.

He said to Chi Ming, "Is there no other way?" ”

Chi Ming shook his head and said: "There is really no way, these proxy servers may have stored the real IP address of the murderer's access to the Internet, but the proxy server is abroad, and we have no way to obtain it, and even if we go abroad, the foreign system is different from ours, and we may not be able to get the data." ”

Wu Long sighed, Director Ba Fei straightened his forehead in anxiety, and said: "Chi Ming, these new technologies will depend on you young people in the future, our old old ways are no longer useful, you have to use your brains to think about it, I only know that there are many ways to go for a problem." ”

Chi Ming's mind wasn't actually listening to what Director Ba Fei was saying, he was just thinking about whether the IP addresses of these proxy servers could be used, and it was impossible to directly enter these servers, but he suddenly thought that when the murderer used the proxy server to access Weibo, he might have accessed other applications.

Thinking of this, his heart warmed up, this function is the latest development of the query system, he immediately copied those IP addresses one by one, and pasted them into another query box, through this query box, he quickly obtained one of the IP addresses to visit a QQ group.

Chi Ming was overjoyed and shouted: "There is a direction, I found out through this IP address that cannot be located that he once visited a QQ group, and when I find out this group, through the analysis of other people, it is possible to crack the relevant information of this person, and there will be no group of people using proxy servers." ”

Director Ba Fei, Wu Long, and Murong Fei all became happy, they knew that Chi Ming still had his own set of rules in the new field of network traces, and hearing him say this, there should be some hope.

Especially the old traces of Ba Fei, he knew that most of the previous traces were limited to fingerprints, palm prints and tool traces, and due to the strict control of the system, the traces of gunshots and bullets were relatively rare.

Now the times have completely changed, as the Internet penetrates into every corner of life, criminals have also left many electronic traces in the process of crime and life, Director Ba Fei has always attached more importance to the cultivation of talents in this area, and Chi Ming is self-taught, and has become more and more handy with network traces.

The three of them only looked at the system that Chi Ming was operating in the computer, this system is a network combat system developed by the Criminal Department with a lot of money and a listed company, but the most troublesome thing about this system is not the technical problem, but the legal boundary, every time it is used, it must go through formal legal procedures, and it must not be used at will, if the police handle the case without boundaries, it will also lead to abuse of power.

Chi Ming had already entered that group, and he found that the group was established a month ago, and there were not many group members in it, only five in total, and the "Evilmaker Terminator" was one of them, but his group member nickname was not this, but changed to "Xiao Ji".

Compared to the other members, "Akichi" is more active in the group, and from his recent words, he is mostly chatting with a guy named "Twilight".

Chi Ming was shocked when he saw the word "Twilight", and he said, "Hey, everyone, come and see, this 'Twilight' can't be our 'Twilight'." ”

When Wu Long heard the word "Twilight", he was also stunned, and he asked, "Does this Twilight have a full name?" ”

Chi Ming clicked on the details of the group members, but did not see any more information.

He said: "The full name is no, but we can take a look at the historical chat history from some time ago, and whether it will mention some useful information." ”

After looking at it for a while, Chi Ming found that this group was not an ordinary group, this was a chat group about suicide, and the members of the group were all people who were depressed and had lost confidence in life, and they had committed suicide in Yuzhou four days ago.

"Meet to commit suicide in Yuzhou?" Wu Long saw the sentence on the screen and said in a lost voice.
