Chapter 8 Incidents
"It really isn't that easy."

In an Internet cafe in Osaka Prefecture, Gao Yuan sat in a private room, looking at the densely packed codes on the computer screen, and expressed such emotion.

A few days ago, Gao Yuan, who left the Lavender Villa, just remembered that he didn't even have a change of clothes for three days, so he bought two outfits at the mall, and then took the subway to Osaka.

I originally planned to take a break in Osaka to see if I could meet Hattori Heiji. After all, cases in this world are always easy to happen around detectives. If you can take the opportunity to get a few cases and trigger more settlement panels, take a look at this "cheat" "Whether there will be new things appear is also something I am curious about and want to do.

Then when passing by this Internet cafe, I saw the announcement of the recruitment of temporary workers.

It just so happened that Gao Yuan had limited cash left after spending the past few days, and a temporary job just met his actual needs.

What's more, in the Internet cafe, you can still access the computer to surf the Internet, and you just have the need to go online to investigate some things.

This Internet cafe has a regular employee who is in charge of maintaining the network and cannot come to work because of an injury not long ago, and recently, the Internet in the store happens to have frequent problems, so it is temporarily looking for a temporary worker who can complete this work To take over the employee's position temporarily.

Coincidentally, Gao Yuan's major in graduate school was information security, and of course he was competent for network maintenance, so Gao Yuan naturally became a temporary worker in this Internet cafe.

Originally, he was only responsible for the work content during the days when the regular employee was away, and the store manager did not check Gao Yuan's identity carefully. After all, it is not easy to find a person who is qualified for this job.

After inspecting Gao Yuan's ability, the two parties discussed the daily salary and provided a private room as Gao Yuan's accommodation during his work, and Gao Yuan lived in the private room and started working.

In the past few days, Gao Yuan stayed in this private room without leaving the gate, maintaining the store's network security while doing his own things.

The work of maintaining the network is very simple for Gao Yuan. For the recent frequent network problems in the store, Gao Yuan found that they were malicious attacks by hackers whose source is temporarily difficult to trace.After telling the store manager about this, the store manager considered that it might be the behavior of a competitor, so he didn't explain too much, just let Gao Yuan complete the work seriously.

But what Gao Yuan did by himself was not so simple.

In the past few days, he tried to invade Japan's household registration system. Although there is no real legal identity card in Japan, there is still a household registration system.

The current identity "Smart Gaoyuan" is a person who does not exist in this world. To completely disguise the identity, of course, the identity of "Smart Gaoyuan" must have a reasonable household registration information. As long as you have this, all subsequent ID documents can be passed. There is a little way to deal with it, but it is precisely this that gives Gao Yuan a headache.

After thinking about it, Gao Yuan felt that the best way was to directly hack into the household registration system and add the "wise Gaoyuan" household registration information, and he did master the technology in this area.

But in the past few days, Gao Yuan felt a headache after the actual operation.I have indeed hacked into the periphery of the system. It is not difficult to forcibly break into the system, but it is impossible to carry out operations without leaving traces and without being discovered.

I have been researching this system for several days. If I want to intrude into the system without being discovered, there is no way unless I have the management key of this system. However, the encryption algorithm of this key is almost completely based on the computing power of the existing computer. Impossible to untie - what to do?

At this time, the page of the program written by Gao Yuan jumped out, which indicated that the regular daily attack on the Internet cafe network started again.

"It's endless, come every day!"

Gao Yuan became impatient looking at this page, but he was steadily operating on the keyboard.

"Every time you use this method, playing a Trojan horse takes up so much bandwidth, I'm afraid others won't find out, right? If it's not that I don't have so much energy recently, I have to find out your source!"

Having said that, Gao Yuan quickly solved the problem.Although it's not a big problem, it's really disturbing if it happens every day.Coincidentally, the black household registration system has not made progress for the time being, why not find out this annoying intruder first.

In the past few days, I have been invaded by Trojan horses at about the same time every day. I have written a defense program, but I am still invaded on time every day. A few days ago, I thought the other party was some kind of expert, but I figured it out these two days. After understanding the characteristics of the Trojan horse program, it became clear that the other party did not actually have such a high means.

As for why it is invaded every day, the answer is actually very simple when you think about it - the other party does not launch an intrusion attack through the network, but an extremely simple, more physical level, directly installing malicious programs on the computer in the Internet cafe.

In other words, the person who surfs the Internet in the Internet cafe every day when the Internet cafe network is attacked is an intruder. You only need to ask the front desk to know who is there.

Thinking of this, Gao Yuan cleaned up the computer usage records, and was about to go out, when suddenly there was an extremely noisy sound outside the door, the sound of exclamation, running and shouting—"He is dead!"

Hearing this, Gao Yuan rushed out the door immediately, and saw that the door of the private room at the end of the corridor was full of people. The store manager and two other shop assistants were there, as well as a few guests who came out after hearing the sound.

After the store manager gave instructions to a clerk next to him, the clerk ran to the front desk of the Internet cafe, apparently going to make a phone call.

It was also at this time that a burly middle-aged man ran in from the Internet cafe, passed by Gao Yuan, came to the door of the private room, looked in, then stretched out his hand and waved away the crowd surrounding here, and shouted loudly.

"Stand back! Don't get close! Protect the scene! Everyone is not allowed to leave here!"

The astonishing aura immediately stunned everyone present, and looking at his figure and appearance, Gao Yuan had already recognized the person coming, and then walked up slowly, wanting to see what happened in the box.

"Excuse me, are you..."

The store manager who was shocked by the other party asked in a low voice.

"I am Otaki Goro from the Osaka Prefectural Police Headquarters."

Otaki Goro said and took out his police card.

"No one went in there."

"Yes, the clerk in our store saw the door of the box that was bleeding so much before opening it. After seeing this scene, no one dared to go in, so I sent someone to call the police. I didn't expect you, the police officer."

The store manager explained.

"I happened to be performing official duties nearby, so I came over when I heard the sound."

Goro Otaki said, walked into the box and roughly inspected the scene.

Gao Yuan also came to the door and saw the scene in front of him.

In the box, a man with his mouth sealed with tape was lying motionless on the sofa, with his right hand resting on the armrest of the sofa, blood dripped from his wrist, and turned into a pool of blood on the ground, extending out the door.

It's just strange that the sofa should face inwards to the computer screen, but now it is deliberately turned to face the door, so that everyone outside the door can see the man's miserable state at a glance—the man was taped. He sealed his mouth, and stared blankly in front of him with terrified eyes, and he didn't close it until he died.

The dead man's bag was turned into a mess, and the wallet was thrown on the ground casually, and there was nothing in it at this time.

Officer Otaki looked at such a scene and couldn't help feeling dizzy.

"How can such a vile crime be committed in a public place! It seems that all the property has been taken away, and the deceased seems to have been tortured... Could it be that the murderer is trying to rob money?"

No, looking at the scene, Gao Yuan denied Officer Otaki's judgment.

There is no doubt that this case is clearly——

"Vendetta!"

Without warning, a young voice with an Osaka accent came from Gao Yuan's side and said the same answer as Gao Yuan had in mind!
