Police Chen Shu

The case told by a police officer from SCT is very interesting, and everyone has to feel that with the progress of the times, the methods used by criminals have also made a huge leap forward, and the technological content and concealment inside are hard to guard against.

Everyone knows that the public security network is a local area network and an intranet, and it is not connected to an external network, including any form of physical connection.

In addition, in the public security system, some documents with a high level of confidentiality registration were originally kept in the archives room. When they were to be used, they were approved by the leaders of the unit, and then printed or copied for use by relevant personnel.

The problem is with the printer.

At that time, the Municipal Bureau purchased a batch of printers with copying functions, and one of them was handed over to the archives office. It took a long time in the archives, and suddenly one day a code appeared on the printer’s display screen, and then the staff called the local after-sales company.

The after-sales company said that it was a hardware problem in the machine, and sent a worker over to repair it. After the machine is repaired, the workers have to take the replaced old parts with them when they leave, saying that the company wants to recycle them.

If this happened in other departments such as criminal investigation, economic investigation or Internet surveillance, they might be let go. However, there are many secret documents involved in the archives room, and the vigilance of the police in charge is naturally much stronger than that of those business departments, saying that they have to check it according to the regulations.

But I took the old hardware that was replaced by the printer and looked at it for a long time, but I didn’t see anything tricky. When I was about to let him go, I happened to meet the police from Kexintong who brought all the equipment to help repair the printer.

Seeing that the machine had been repaired, the policeman used the tools at hand to dismantle the replaced old parts, only to find that there was a tiny memory inside.

Later, I turned the memory upside down, only to find that all the data stored in it were printed, copied, and scanned by the printer. When the memory is full, an error code will pop up on the printer’s display to prompt after-sales service. Free replacement parts.

If this thing is sold and sent back to the head office in Southeast Asia, it will be leaked.

Later, I gave a few examples from other provinces, including installing a scanner on a shredder, installing a cache device on a power strip, etc. These are all experiences of people who have been there, and everyone carefully recorded them in their notebooks.

All the people present here are old police officers. Even if they have never seen these cases, they have heard of them more or less, so they are not as surprised as they imagined.

Jiang Hai, who was only a high school student a few months ago, is different. As a freshly released reserve police officer, he is very motivated to study and pay attention to policing.

He had been pestering Chen Shu to ask questions on the plane before, but now he was very excited to hear so many new things, so he naturally found Chen Shu who was sitting next to him.

"Brother Shu, is that an exaggeration?"

Chen Shu pouted his lips at the policeman standing in the corner who was taking pictures with his DSLR, and said in a low voice, "Sit down first, keep your back straight, and take notes."

After the policeman in charge of publicity finished taking pictures, looked at the small screen of the camera and left, Chen Shu briefly talked to Jiang Hai.

"In the future, you will have "Investigative Science" in your classes. At that time, the teacher will tell you about such confidential and confidential cases. I remember that these techniques were things a long time ago. I heard about them when I was studying. .

"Back then we were still using mobile phones with removable batteries, and it was popular to remove the mobile phone batteries during meetings. In fact, this kind of precautionary measure was useless.

"Our bureau has a van with a very ordinary appearance, which is full of technical equipment. I remember that it seems to be able to transmit power to the mobile phone at a distance of 300 meters in a straight line, and then call up the call records and text messages inside. It's even more ruthless. What’s more, it can directly transform this controlled mobile phone into a monitoring device, and the live sound pickup effect is quite good!”

Jiang Hai's eyes were shining, and he grabbed Chen Shu's arm and asked him to talk more.

Chen Shu shrugged and regretted, "After graduation, I went to the special police and the police station, and I never touched these things again."

"."

The formal exchange meeting lasted until after six o'clock in the afternoon. After the meeting, Lin Dakai was naturally surrounded by the local police, and chatted with each other about their respective police experiences and experiences.

Lin Dakai has experience in peacekeeping abroad, especially the area he went to, Nansuxdan, which is known as one of the most dangerous mission areas with the worst sanitation conditions in the United Nations.

Chen Shu saw that Lin Dakai was surrounded by people and couldn't leave for a while, so he pulled Jiang Hai to ask him to help find Zhu Li together.

Judging from the itinerary, after their investigation at the Kashi City Public Security Bureau, they will go to the higher-level Kashi District Public Security Bureau. Judging from the time, they are already a little nervous.

The two left the meeting room and wandered outside for a long time but couldn't find anyone. Chen Shu took out his mobile phone and made several calls, but no one answered.

Chen Shu thought for a while, and went back to the conference room to find Wang Hao: "Wang Hao, is the material examination room here?"

"What room?"

"Criminal college, forensic doctor, corpse."

"Oh, the Criminal University is in the small building at the back. Where did your female colleague go? Isn't she a forensic doctor?" Wang Hao was a little curious, logically saying that no woman would be interested in these places.

Even if it is a forensic doctor, there is a high probability that no one will take the initiative to touch these things unless it is necessary for work. After all, it is touched every day on weekdays, so there is no need to make yourself uncomfortable during non-working hours.

Chen Shu remembered the on-site investigation box that Zhu Li had brought all the way from Dongzhou, and said with a hand on his forehead, "Yes, she is a forensic doctor."

Material appraisal room.

Standing outside the iron gate, Zhu Li smiled and said to a young policeman with dark eyes, high nose and shaven chin, "I'm here from East China Sea for research, open the door."

"No, I don't know you, you can't enter here." The white coat shook his head, and then he was about to leave.

Zhu Li took out her police ID and shook it: "We are all colleagues, what are you afraid of?"

"No, I haven't been notified, so I can't let you in."

Zhu Li let out a long sigh, and said helplessly, "Brother, why are you so stubborn when you're young? It doesn't matter if you don't know me, my police ID can't be faked, right? You're all in the police station, what are you afraid of?" .”

Zhu Li, who never gave up her persuasion, heard a sound from behind.

"Our place is different from yours in Donghai. It's right to be cautious. Tu Xunjiang, these two came from Donghai Provincial Police Academy to investigate in our bureau. If there is nothing important in your room, just open the door. "

It was Wang Hao who accompanied Chen Shu all the way from the office building to speak.

"Brother Hao, you are here!" Tu Xunjiang's originally stiff expression immediately eased after seeing Wang Hao, and he pressed a button by the door with a "snap", and stretched out his hand to pull the iron door open .

Wang Hao, as the team leader who came to support from the counterpart city, is quite popular in the local public security bureau.

"It's nothing important, but a charred corpse was just delivered in the morning, and I'm busy." Tu Xunjiang opened the door and welcomed the group of people in.

Corpse!

It's better to come early than to come early!

Julie became happy all of a sudden, her eyes were curved into crescent moons, and the corners of her mouth were almost grinning to her cheeks.
