When Bei Changan found out about this group of hackers, it was already a week later.

It was May 12th.

When Su Xiao opened the tracking software, he found an important piece of information.

In the tracking feedback of the past week, he found that this group of hackers, although they are very hidden, but there is one point, which makes them exposed.

These people, every time they get permissions, will subconsciously switch virtual IPs.

And every time they switch over, they will frequently feed back the permission data to the three same base stations.

Su Xiao summed it up, and he thought that there were three reasons for the other party's approach.

First, it is deliberately done to create a false image.

Second, there is another plan to confuse the opponent.

Third, they made their own mistakes.

For the last point, Don't Chang'an directly ruled it out.

Because he felt that this kind of mistake would not have appeared in such a hacker gang, at least for now, their technology is absolutely excellent, and in many ways it is perfectly done.

They should do this because they want to confuse everyone, and then fish in troubled waters to hide themselves.

But isn't it a bit too much to do this?

Isn't this a clear sign that your opponent is based here?

What do you mean?

A little off.

Would a veteran hacker gang make such a low-level mistake when playing games with their opponents?

Don't Chang'an, think not.

……

……

……

However, Su Xiao still reminded Bei Chang'an, and he said: "Third brother, low-level mistakes are not impossible, reverse thinking is applicable in many cases. Do you think they won't, but they just know that they can't do it? Some masters like to play this game, and they like to figure out the psychology of their opponents......"

After he finished speaking, Don't Chang'an thought about it and felt that it was not unreasonable.

After all, sometimes the most dangerous thing to do is the safest thing to do.

The opposite effect is often unexpected.

So, are they putting on a maze?

After a while, Bei Changan looked at Su Xiao and said, "Well, it's a bit interesting." But isn't the price of such an approach a bit too great? In any case, once you expose your tracks, you basically have nothing to play. ”

Su Xiao nodded, he was also a little undecided, he said, "That's it." I'll communicate with Wu Ming first and see if he has any ideas. If the idea makes sense, it should be able to find this group of people in no time. ”

"Okay, then please. Wu Ming's side, if he is not willing to help, let's not force it. ”

"Well, got it. ”

……

……

……

QQ.

When Su Xiao told Wu Ming about this, Wu Ming only said one sentence.

"This kind of play is a double-edged sword. Play well, you won't find anyone for the rest of your life, but once it's exposed, they'll finish playing themselves. As for the problem of the base station, it is also very easy to solve, and the only criterion for distinguishing the real from the fake is the data. People lie, IPs lie, but the data that is fed back does not. In order to hide their communication data, some hacker gangs usually find something irrelevant to cover up, and they may gain something from here. ”

……

……

……

Wu Ming's meaning is that the countryside surrounds the city, finds a breakthrough point, and saves the country by curve.

Because now, Bei Chang'an can't find them out all at once, so he must start from other aspects.

According to his ideas, Su Xiao classified the data of the base station, trying to find clues from it.

That afternoon, Yao Jianjun, Su Xiao, and Bei Chang'an decomposed the smoke bombs thrown at them by the hackers in detail.

On the evening of the 12th, the three of them got a very important piece of information after many data comparisons.

The way of communication of the hacker gang!

This group of people usually doesn't stay on the base station for a long time, but in recent hours, they have shown their feet in the data.

Don't Chang'an Shun Teng touched the melons and dug up a platform for them to exchange information.

This platform is not an ordinary BBS, nor is it a website, it is a personal homepage about art appreciation.

The group did not use computer language when communicating.

They are clever enough to use web content to disguise themselves and encrypt conversations and incorporate them into the bios of well-known artworks.

These people rely on their own understanding of artworks and use a unique language logic to express themselves, and if they don't look closely, they really can't see it.

Bei Chang'an asked Su Xiao: "Can their identities be found?"

"I guess I can try to get into the backend of their page. If it goes well, the details of these people should be fully grasped. ”

Don't Chang'an asked again: "Okay, don't be discovered, give up if you can't do it." ”

"Well, got it. ”

……

……

……

In the early hours of May 13.

Su Xiao disguised his identity, quietly entered the backstage of the art website, and copied the encrypted content, and then decrypted it with code.

The three of them fought all night, and finally completed all the work and dug up the information of the hacker gang.

The gang consists of four people, and the netizens of these four people are all taken from famous artists, named "Picasso", "Leonardo da Vinci", "Van Gogh" and "Raphael".

The four of them have a clear division of labor online, and Picasso is the technical core of the entire team, as well as their leader.

Leonardo da Vinci was the programmer on their team.

Van Gogh was a great decipherer.

Finally, Raphael is an expert in technical offense and defense.

The four are from different places, but they are all in Yanjing at the moment.

From the content of the chat, Bei Changan also obtained a very key information.

That is, in real society, they usually have only one joint place, which is a bar, called "Norwegian Wood"

Yao Jianjun looked at the name and muttered, "What do you mean?"

Su Xiao explained to him: "It's the name of a novel. ”

"Who wrote it?"

Haruki Murakami. ”

……

……

……

The name of the bar, don't Chang'an seems to have a vague impression.

Later, Su Xiao reminded him that this was the bar that Jiang Tong showed the scene.

Don't Chang'an finally remembered.

At dinner that day, Jiang Tongbao once passed by the house.

Don't Chang'an also knew that he was watching the scene at the bar, but he didn't take it too seriously.

Su Xiao asked, "Third brother, what should I do?"

Bei Changan thought for a while and said, "Study it first, see what path they have, don't alarm them." At the bar, I said hello to Ye Kai and asked him to talk to Jiang Tong to see if I could find these people. ”

Su Xiaodao: "Looking at their chat content in recent days, in addition to the interaction data, a person named "Li Chen" was also mentioned. ”

"Li Chen, what is the origin of this person?"

Su Xiao shook his head, and then said: "What is the origin, I don't know at the moment, but looking at the tone of their voice, they are either friends or employment." The mastermind we are looking for is likely to be a person. ”
