I don't want to solve the case when I'm a little policeman.

Chapter 251 Sudden Cases
Just when Xu Zheng was about to continue talking, Political Commissar Song of the Suyun City Criminal Police Detachment came over. It turned out that a bank in Suyun City had an emergency, and the Suyun City Criminal Police Detachment needed urgent support.

The matter was urgent. It was a bank executive who called the police. He was in charge of the bank's major customer resources. One of the customers called him 10 minutes ago and said that the money in the customer's bank card had been transferred directly to 200 million. , because his client's daily transfer limit is 200 million, and by the time his client realized this situation, the money had already been transferred.

The bank executive immediately called the police, and 110 quickly contacted the Suyun City Economic Investigation Detachment after receiving the report. However, this case was more urgent because the bank executive received several calls to the police, and the money was also transferred away.Therefore, the Economic Investigation Detachment asked the Criminal Police Detachment to assist them in handling the case. They were responsible for tracking and intercepting the money, and Qu Hou was responsible for finding the suspect.

The case is really urgent, because the money of five major bank customers has been transferred away, and it is not known whether anyone will suffer further losses.If the case cannot be solved and the money recovered in a short period of time, it will be difficult for the bank and the government will be even more difficult. If the government is difficult, the pressure on the police will be very heavy.
Therefore, the research meeting had to be suspended, and Qu Hou told Wan Haihong and his colleagues about the situation, "Team Wan, Xu Zheng, I will borrow it first, and when we go over there to have a look, if we can, we will directly If you can’t do it, then you can’t.”

Wan Haihong also understands that when a bank is involved in this kind of case, the local government will treat it with caution. In addition, this case is obviously an emerging financial crime, so the police really need to pay attention.

"You guys go first, just to let Xu Zheng know about this kind of case and learn."

Qu Hou took Xu Zheng upstairs to the Economic Investigation Detachment.

To be honest, in general, the criminal police detachment is the general name of the criminal investigation detachment and the economic investigation detachment, but now the status of the economic investigation detachment has been raised due to the increase in such economic cases, so it has become, the criminal investigation detachment is the criminal police detachment, The economic investigation detachment has become a department parallel to the criminal police detachment.

Of course, the situation varies from place to place. Some criminal police detachments still include criminal investigation and economic investigation, while others have become independent.

Like Suyun City, the economic investigation is a detachment independent of the city bureau.

Chu Ya, the head of the Economic Investigation Detachment, saw Qu Hou coming here with the elite of the detachment, hurriedly walked over with their Political Commissar Wang, exchanged some polite words, Chu Ya pointed to Xu Zheng and asked, "Your detachment recruited again?" A young man? Looks very energetic."

Qu Hou smiled, "I'd rather keep him in our detachment, but unfortunately this young man is not simple, Xu Zheng, Xu Zheng from Changming City Criminal Police Detachment, Lao Chu should have heard of it, right?"

"Oh, you are Xu Zheng. You have known your name for a long time. Yes, Xu Zhengyi is here to handle the murder case on a rainy night, right? How is it? Do you have any clues?"

Xu Zheng hurriedly replied: "Chu Detachment, Political Commissar Wang, two leaders, I just arrived today. We are discussing the rainy night murder case."

Chu Ya patted Xu Zheng on the shoulder, "Haha, that's my fault, it delayed your handling of the case, but there's really no way, this case is really urgent on our economic investigation side, we really need you experts in criminal investigation to help us analyze it .”

The crowd didn't stop being polite, and quickly got to the point. It turned out that the people whose money was transferred out happened to be attending a corporate summit. Because they attended the meeting, they muted their phones. After the summit, they didn't find out that the money was transferred out. .

Until someone deducted money because he wanted to buy something for his girlfriend, the system reminded him that the limit for today was exceeded.

You must know that they are senior VIPs of the bank, with a daily limit of 200 million, how could the limit be exceeded, so this person hurriedly contacted the bank executives for verification, and only then did he know that the money in his card had been transferred.

Qu Hou asked: "In a case like this, the money has already been transferred away. Isn't it enough for your economic investigation to arrest people along with the money?"

Chu Ya smiled wryly, "You old man, the case is so simple and we still need your help?"

He waved his hand and asked one of his young female investigators to introduce the case. The female investigator glanced at Xu Zheng, "Generally, individuals only need to know the mobile phone number, bank account number, account name, and ID card for private transfers online. The most important thing is the SMS verification code of the mobile phone when applying for a bank card."

Qu Hou waved his hand, "Xiao Liu, hehe, you don't need to popularize the basic knowledge for us criminal investigation team members, especially Xu Zheng, don't you think he doesn't understand economic investigation at all? It's okay, tell me what the suspect in this case is doing Arrived."

Officer Xiaoliu was stunned for a moment, "Detachment Qu, then you can make things difficult for me, because our economic investigation colleagues were also discussing just now how the suspect committed the crime. Suspects such as other mobile phone numbers and bank accounts may be involved. Arrived, but the mobile phone SMS verification code, how they did it, we have no clue yet.”

Chu Ya is also an old economic detective. He is about 50 years old and has white hair. "We have checked the cameras at the summit site and asked these victims and the people around them. Also, their mobile phone operators, We have all known it, but we don’t know how these criminals got the verification code of the victim’s mobile phone SMS.”

Xu Zheng's heart moved. After all, he has intermediate hacking knowledge, and there is no need to hide his secrets at this time. He raised his hand, "Chu Detachment, Qu Detachment and Political Commissar Wang, I think I know what's going on."

Chu Ya and Political Commissar Wang looked skeptical, Qu Hou smiled in satisfaction after being stunned, and the participating colleagues below all stared suspiciously at this rising star of Changming City.

Xu Zheng didn't make a fool of himself, "Actually, if there is a network expert on the criminal investigation side, well, this expert should be more skilled."

Seeing Xu Zheng talking nonsense here, Qu Hou hurriedly urged, "Your boy will explain how tall you are later, so hurry up and tell me what's going on. The economic investigation colleagues are all anxious!"

Chu Ya glared at Qu Hou, but at this time he followed his words and said, "Xiao Xu, you have to be frank, we are really anxious about this case."

"I personally think that the suspect did not come to the scene in person. He should be outside the corporate summit, and the distance will not exceed 500 meters. This is the case. He must have known that these victims attended the summit today, and then he prepared a set of equipment. , this set of equipment can transmit signals to the outside.

Well, it is actually a fake base station. He used this fake base station to intercept the verification codes sent to the victim by banks and online transaction terminals. He intercepted the verification codes and added the victim's information such as his mobile phone number.

Therefore, he was able to transfer the money in the victim's bank card. "

Then Xu Zheng explained to them the interception process of personal mobile phones, signal towers, banks, online trading terminals, and pseudo base stations.

The Economic Investigation Detachment did not have such a high-level network technology expert, but Chu Ya chose to believe Xu Zheng, "Xiao Xu, you just said that the suspect should be within 500 meters of the summit. If he wants to set up such a fake base station, it must be in the car.

It can't be in the basement of the summit, it's in the street parking lot, right? "

Xu Zheng nodded, "The average person who makes a fake base station is definitely not small, plus it needs to use 100 batteries, the minimum is two yuan, so there are at least two suspects, one of whom is driving, and the car must be a van, or else It's a seven-seater car.

Moreover, his car has to move for about 10 minutes, so as to ensure that the fake base station will not be detected by the communication company. "

He was talking about his conjecture here, and there were also two colleagues from Tuju who came to the meeting. They checked the parking lot near the summit according to Xu Zheng's statement under the Sky Eye system.

I quickly locked up a van. There was no way. All the people who came to the summit were rich and big bosses. There were several parking lots nearby, including the roadside. Parking on the roadside was not allowed, and the traffic police would not allow it.

There are very few vans in the parking lot, and of course there are many seven-seater commercial vehicles, so under careful observation, this van changed parking spaces within 10 minutes, so this is very conspicuous.

After finding a suspicious vehicle, the Sky Eye system searched, and soon, the vehicle's driving license information, license plate owner, and most importantly, the location of the car were all displayed on the big screen.

Including the looks and personal information of the two people sitting in front of the van.

This is the Sky Eye system, as long as it can be found, the information can be summarized very quickly. When Qu Hou saw this situation, he stood up and laughed, "Old Chu, how is it, the reinforcements I invited for you are not bad, haha, turn around Don't forget to treat your guests to dinner."

Next, Qu Hou took Xu Zheng and the others to prepare to leave. The information of the suspects in this case was thoroughly searched, and even the current location was found. The Sky Eye system also locked these people, so the case can save the arrest and interrogation to get the money back. Come.

Therefore, everyone returned to the criminal police detachment's research and judgment room with pride amid the thanks from Chu Ya and Wang instructor.

Seeing that they came back within half an hour after going out, Wan Haihong hurriedly asked what was going on, and when Qu Hou explained the matter, Wan Haihong was amazed, "Xiaozheng's ability is worthy of recognition, but this case is indeed quite novel. The idea of ​​a fake base station intercepting SMS verification codes is a genius."

Qu Hou smiled, "Team Wan, are you praising the suspect, or Xu Zheng?"

Wan Haihong shook his head, "Okay, when the economic investigation in your city finishes handling this case, we have to study within the system. It seems that the methods of criminals are becoming more and more sophisticated, and we have to keep up with our studies."

The two leaders were chatting at the other end of the meeting room. Of course, Xu Zheng and the others were not idle. After discussing it, the conclusion was that this case did not have a certain network technology, and it was impossible to think of a point to solve the case, so Xu Zheng's rich knowledge was the key. The key to solving the case.

Everyone can only envy, but cannot learn, so the judgment room has become a meeting to praise Xu Zheng.
