"It's not that easy."

In Osaka Prefecture, in an Internet café, Takato sat in a private room, looking at the dense code on the computer screen and exclaimed.

A few days ago, Takato who left the lavender villa remembered that he hadn't even had a change of clothes for three days, so he bought two outfits at the mall and took the rail to Osaka.

I was going to fix it in Osaka.,See if you can meet Hattori Heiji.,After all, the cases in this world are always easy to happen around the detective.,If you can take the opportunity to rub a few cases.,More triggers the settlement panel.,See if there will be something new in this "plug-in" It's also something I'm curious to do.。

Then just as I was passing by this Internet café, I saw an announcement for the recruitment of temporary workers.

It just so happened that after the expenses of the past few days, Gao Yuan's cash was limited, and a temporary job just met his realistic needs.

In addition, in the Internet café, you can also access the computer to surf the Internet, and you just need to go online to investigate some things.

This Internet café has a regular employee in charge of maintaining the network who was injured not long ago and is unable to come to work, and it happens that the network in the store has been experiencing frequent problems recently, so it is temporarily looking for a temporary worker who can complete this work to temporarily replace the employee.

It just so happened that Gao Yuan's major in graduate school was information security, and he was certainly competent for the work of maintaining the network, so Gao Yuan naturally became a temporary worker in this Internet café.

Originally, he was only responsible for the work during the absence of the regular employee, and the store manager did not carefully check Takato's identity, after all, it is not easy to find a person who is qualified for this job.

After inspecting Gao Yuan's ability, the two sides talked about the amount of daily salary and the provision of a private room as a place to stay during Gao Yuan's work, and Gao Yuan lived in a private room and started working.

In the past few days, Gao Yuan has not come out of the gate, but he has nested in this private room, maintaining the network security of the store while doing his own thing.

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

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

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

The current identity "Wise Gaoyuan" is originally a person who does not exist in this world, to completely disguise the identity, of course, to let the identity of "Wise Gaoyuan" have a reasonable household registration information, as long as there is this, all subsequent identity documents can be handled by a little means, but it is this that makes Gao Yuan very headache.

After thinking about it, Gao Yuan felt that the best way was to directly hack into the household registration system and add the household registration information of "Wise Gaoyuan", 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, and it is not difficult to forcibly break the system, but there is no way to carry out the operation without leaving a trace and being discovered.

I have been studying this system for a few days, and if I want to invade the system without being discovered, unless I have the management key of this system, there is no way, but the encryption algorithm of this key is almost impossible to unravel with the computing power of the existing computer - what should I do?

At this time, the page of the program written by Gao Yuan jumped out, which showed that the daily fixed attacks on the Internet café network began again.

"It's endless, come every day!"

Gao Yuan looked at the page impatiently, but kept working steadily on the keyboard.

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

Saying this, Gao Yuan quickly solved the problem. It's not a big deal, but it's like it every day, and it's really exciting. It just so happens that there is no progress in the black household registration system for the time being, so it's better to find out this annoying intruder first.

In the past few days, I have been invaded by a Trojan horse every day, and I have clearly written a defense program, but I am still invaded on time every day, and a few days ago I thought that the other party was a master, but in the past two days, I figured out the characteristics of this Trojan program and understood, the other party actually did not have how high the means.

As for why it is hacked every day, in fact, the answer is very simple - the other party is not an intrusion attack through the network, but a very simple, more physical level, directly installing malicious programs on the computer of the Internet café.

In other words, the person who surfs the Internet in the Internet café every day when the Internet café network is attacked is an intruder, and you only need to ask the front desk to find out who there is.

Thinking like this, Takato cleaned up the computer usage records and was about to go out, when suddenly there was an extremely noisy sound outside the door, exclamations, running sounds, and a shout - "He's dead!" ”

Hearing this, Gao Yuan immediately rushed out of the door, only to see that the door of the private room at the end of the corridor was full of people at this time, the store manager and the other two clerks were there, and there were a few customers who heard the sound.

After the manager gave an order to a clerk next to him, the clerk ran to the front desk of the Internet café, apparently to make a call.

At this time, a burly middle-aged man ran in from outside the door of the Internet café, passed by Gao Yuan, came to the door of the private room, looked inside, and then stretched out his hand and waved away the people surrounding here, and shouted loudly.

"Stand back! Don't come closer! Protect the site! No one is allowed to leave here! ”

The astonishing momentum immediately calmed everyone present, and looking at his figure and appearance, Gao Yuan had already recognized the person, and then slowly walked up, wanting to see what was going on in the box.

"Excuse me, ...... you are?"

The store manager, who was shocked by the other party, asked in a whisper.

"I'm Goro Otaki from the Osaka Prefectural Police Headquarters."

Goro Otaki said and took out his police ID.

"No one has been in the scene."

"Yes, the clerk in our store saw the box door that was opened with so much blood flowing out of the door, and no one dared to enter after seeing this scene, so I asked people to call the police, but I didn't expect you, officer."

The store manager explained.

"I happened to be in the neighborhood on official business, and I came over when I heard the voice."

Goro Otaki said, walked into the box and took a cursory look at the scene.

And 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 duct tape was lying motionless on the sofa, his right hand resting on the armrest of the sofa, blood flowing down his wrist, flowing on the ground into a pool of blood, and extending out of the door.

It's just strange that the sofa was supposed to face inward facing the computer screen, but at this moment it was deliberately turned in a direction to face the door, so that everyone outside the door could see the man's tragic situation at a glance - the man was covered with duct tape, staring at his eyes in a stunned daze, and he didn't close it until he died.

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

Officer Otaki couldn't help but feel his head big when he looked at such a scene.

"How can such a bad case be committed in a public place! It was as if all the belongings had been taken away, and the deceased seemed to have been tortured...... Could it be that the murderer is trying to rob money? ”

No, looking at this scene, Takato 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 Takato's side and said the same answer as Takato had in his heart!
