Nanqian Province is too far away, and Bai Song can't reach for it at all, according to Senior Brother Ren Hao, the probability that this case is purely coincidental is higher.

Putting these things behind him for the time being, Bai Song checked the translation software, slowly finished the translation, took the equipment to the Cao detachment, and roughly explained the company situation of the equipment and the status of the equipment.

"Literally, this thing doesn't have the function of eavesdropping, right?" Cao Detachment was a little relieved: "I'll arrange someone to study it later." ”

"Okay, then Cao Detachment, I'll continue to go out tomorrow for interrogation, okay?" Bai Song asked.

"Go ahead. ”

After the Cao detachment finished speaking, seeing that Bai Song was not moving, he was a little puzzled: "Why don't you leave?"

"Uh... Cao detachment, can I apply for a car..."Bai Song prayed for his fuel tank, people are poor and short-sighted...

"Okay, use it, take it from the king's team. After the Cao detachment finished speaking, he continued: "But in the future, if you are nervous about using the car, try not to occupy the bus, after all, I can't tell other leaders about this matter when you go to interrogate." ”

"Thank you, Detachment Cao!" Bai Song happily ran away.

In another three or five days, a few detention centers that are relatively far away will be able to run away, and the rest, about ten kilometers, will not be distressed with their own cars.

After returning to the house, Bai Song contacted Wang Liang first.

Wang Liang took the high-speed rail and just arrived at the destination, and told Bai Song that the GPS coordinates are a bit troublesome, and he may have to wait for a while.

This is not in a hurry, Bai Song knows that even if he knows the coordinate point, he will not go over for a while, and because there are other cars pulling away these goods that are suspected to be money, the coordinate point is not necessarily effective.

Bai Song asked Wang Liang for a while, if you have other inquiries and need to go to the local public security bureau to investigate relevant information, you can help check the car by the way.

This kind of car, looking at the entire Shonan Province, should not be many. I just don't know if the local query system supports the search method of directly querying the car model.

After chatting with Wang Liang for a while, Bai Song found that the WeChat group in the class was chatting happily.

Yesterday, I talked about some strange cases at the police station, and the students were very interested. Of the thirty or forty classmates in Bai Song's class, half of them went to the police station, and most of the rest were in government agencies, and there were some people like Zheng Chaopei (who resigned) and Zhou Xuan who did not become police officers and who were admitted to graduate school, and everyone chatted very well in the group.

At the current stage, the vast majority of serious violent crimes, such as homicides, can be effectively cracked down, but many cases, such as telecommunications fraud, have been difficult to satisfy the people.

The detection rate is not high, especially for small frauds, once a fake ID, fake username and the like are used, the cost of crime is not high.

When Bai Song was in the third team before, Wang Liang had a lot of telecom fraud cases, and many of them couldn't be solved in the end, so it was good that they could be handed over to Wang Liang. There are many small scams in the game, and some of the prices are as low as a few cents or even a few cents in RMB!

This is really not, for example, a game Dungeon and Warrior that was listed in China in 2008, there was a low-level picture called Zombie King, with a 3000 game currency (according to the price at that time was about two cents), many people just collected the money and ran away, of course, this is also a fraud, and someone really called the police.

There are too many cases, too many fake information, fake IPs, too many VPNs... In short, it is very troublesome. The best way to crack down on this kind of fraud case is to combine crackdown and prevention, on the one hand, and on the other hand, publicize and prevent it.

When we talked about this, we called on each other.

Do a little thing together, do more publicity, and if you can see more people, you may be less fooled.

I have to say that the power of the number of people is still very great, and some anti-fraud knowledge was organized, and everyone shared it through their circle of friends and social accounts, and Zhou Xuan, a big V in the live broadcast industry, became an important figure in this event.

The most common scams are summarized below:

Send a QR code directly to borrow money (popularized at the end of 2013, and now this technology has just appeared);

Online part-time jobs;

Investments with an annual interest rate of more than 8%;

Scams...

...

This is a good thing, Bai Song suddenly thought that his own blog seems to have hundreds of thousands of fans!

turned off the notification, Bai Song re-entered his account, forwarded what everyone wrote, and then closed a certain blog.

...

When it was time to get off work in the afternoon, the Cao detachment called Bai Song again and asked Bai Song to go.

It seemed that the situation of the equipment had been settled, and Bai Song trotted all the way to the office of the Cao detachment.

"No storage equipment?" Bai Song listened to what the Cao detachment said, and was very puzzled: "What is this thing?"

"The technical department said that it was a repeater, and the RF band was ultra-short-wave, but the specific meaning was not mentioned in the report. The Cao detachment handed a brief report to Bai Song: "You college students, these are all high-achieving students, what do you mean by telling me." ”

The reports have come out? Is it something that the leaders are concerned about, but it's different... Bai Song took the brief report, and after reading it, he explained to the Cao detachment: "Our common Wi-Fi is ultra-high frequency radio waves, with a wavelength at the centimeter level and a short transmission distance. This thing is a very high frequency radio wave, with a long wavelength, in the range of 1-10 meters, and a long transmission distance. To put it simply, our common FM radio is this kind of meter wave, and the common AM radio is medium wave, and the wavelength is 100 times that of FM. ”

"Do you mean to say that this thing is emitting FM broadcasts?" Cao Detachment understood, everyone has used semiconductors.

"No, it's a far difference. This is a repeater, the black radio station in Tianbei District before, it is not high-tech, but it is better than power. This thing is an adaptable repeater that can send signals to those black stations for control and playback.

The black radio station can't be directly connected to the mobile phone, but through this repeater, the content on the mobile phone can be played directly, and there is no storage device, even if we find it, there is no good clue. ”

"This is no ordinary suspect. The Cao detachment nodded: "Since it doesn't involve the secrets of our corps, it's okay." But we can't take it lightly, the leaders of the corps know about this matter, so don't you want to go out to get the transcript recently? I'll arrange a car for you, you take your drone, turn around the rooftops of the high-rise buildings and the tops of some unmanned factories in the vicinity, and tell me in time if you find any findings. ”

"Okay Cao detachment, I've been going around a lot these days. Bai Song replied seriously.

"Well, I'll give you a key, you take it. Cao Yuandao took out a car key: "You can use this car casually for the past two weeks, and if there is any idleness, it will be handed over to the Wang team." ”

"Okay, thank you Detachment Cao!" Bai Song was overjoyed.
