"Have you found the other party's mobile phone number?" In a business car with an inconspicuous appearance, various electronic instruments were hung on both sides of the car. Miao Zhishun, dressed in a suit, leather and black leather shoes, sat in the car with a high expression, and Azu next to him quickly operated the keyboard with both hands.

"It's still under test. Now there are all kinds of unnamed phone cards on the market. Every time these guys commit crimes, they change their phone cards that they contact each other. Now they don't know how much they call." Azu said while operating: "There are hundreds of communication signals in the area we locked in at present, and they will not be able to detect the specific number of phone calls of the other party in a short time."

"This won't work. Brother Yao won't wait for so long." Miao Zhishun touched his big back and thought about it and picked up the phone and dialed it out, "Big D, I'm Miao Zhishun."

"Yo, Miao Sir, what's the matter?" Big D asked with a smile.

"I have a task here. I want to find a mobile phone number named Duan Feihong. His family lives on your side and send someone to his address. People in their decades must have relatives and friends. I ask if he has a fixed phone number." Miao Zhishun told Da D the address of Duan Feihong.

"I'm sorry, wait for me." After hanging up the phone, Big D immediately gave an order to his younger brother below. The club is different from the police, and the power can be mobilized, especially at the bottom, far exceeding the police.

More than ten minutes later, Miao Zhishun got the fixed number commonly used by Duan Feihong.

After all, people must have a social circle when living in this society. Even if they are a hidden killer, they cannot leave society.

It is easy to deal with with a goal. The current telephone technology is not complicated. To put it simply, each card represents a fixed code. It is equivalent to a locator when plugged into the mobile phone. When someone dials the number represented by the phone card, it will be connected to the other party through a program-controlled exchange device and a signal tower covering the entire Hong Kong Island everywhere.

After knowing the phone number, you only need to invade the SS7 signaling system protocol of the cellular network, and you can easily lock the other party's position through the system, pretending to the other party's number and synchronously translating and monitoring what the other party said during the call.

Going further, through the telephone card's contact signal with the signal tower in real time, directly invade the mobile phone through the signal, turning the other party's mobile phone into a wiretaper under its control.

Of course, it is not possible for anyone to achieve the SS7 signaling system protocol through a cellular network. It is either the police, the telecom operator, the big guy with relationships and wealth, or the super hacker with super technology and sufficient advanced and expensive equipment.

Miao Zhishun represents the police, which is not considered an invasion but a direct entry into the system.

"Okay, successful." Azu hit the Enter key, and the other party's signal was directly connected to the car. "With this basis point, I can analyze and find out the mobile phone number they used for business."

Even if things come to an end here, the rest is time.

"These guys are too cunning, it's hard to catch them."

"We don't need to worry about this. Our task is to find out how many members they have and what positions they are responsible for. The rest is monitoring. How to break the deadlock is Brother Yao's business." Miao Zhishun unscrewed a bottle of Coke and drank it in for two mouthfuls, which was great.

...

"Brother Yao, this is the information." Miao Zhishun handed over a document, "There are a total of four people, a combination of three men and one woman."

"It's so fun?"

Miao Zhishun: “…”

"Let me see, take good care of the boss, woman, fat man, damn, it's quite simple and clear, it's really fucking uncharacteristic."

"Tsk tsk, there is not even a name, so it's hard to come up with even recordings as evidence."

"But it doesn't matter." Wang Yaozu took his cell phone and called out, "Is there any such a young actor with good acting skills in the company, but because of his ordinary appearance, he has no reputation."

"Okay, I'll design an identity for you, you can take it over and let the other party practice, okay, that's it, I'll follow my arrangements later."

"Don't we have people from the police station?" Miao Zhishun touched the cigarette on Wang Yaozu's desk and lit one.

"No, the policeman smells too strong." Wang Yaozu shook his head and said with a serious look: "Although these guys are also killers who kill people, their methods are completely incomparable to those who hold swords and guns. The kung fu that those people rely on, these guys are brains and never put themselves in a dangerous situation. Whether they succeed or not, they will not implicate themselves."

"These guys have too strong control over details. They are careful not to leave any flaws when they are tied. This is the first time I have encountered it. If they use their own people from the police, they will definitely be noticed."

"To be honest, I admire them very much, especially this boss, who plays like this every day and is not bald, fucking..."

...

"Mr. Huang, you can throw away the soda and turn it into Yaliao Street." A man wearing glasses and holding a bottle of Pepsi in his hand answered the phone and put the coke bottle in his hand on the trash can and walked towards Yaliao Street with the phone.

"Now stop, pick up a plastic bag in the trash can beside you, put the wallet, phone number, ID card you brought in, and keep going."

"What should I do?" the man put everything in as he walked, and then asked to the phone.

"I've seen No. 165."

“Go to the sixth floor!”

The man in glasses pressed the elevator, and the elevator door opened. Before he could enter, another sound came from the phone.

"Hang the wire, put the phone in a plastic bag, and throw it outside."

The man looked up at the closed circuit surveillance camera on the stairs, put his phone in a plastic bag and was still outside, and the elevator door was closed.

After finishing everything, the fat man turned off the phone and took out the phone card and broke it and threw it into the sewer on the side of the road. Then he picked up the plastic bag and turned around and left.

When I walked around for a few times, I had nothing in my hand.

After waiting for a long time, I read the text message on my phone, boarded the double-decker bus at the reservation location and went to the top floor to find the boss sitting behind. I put my small shoulder bag on my seat, took a hot dog and ate it, "It tasted good."

The boss picked up the bag and took out a book, took out a photo and looked at it with an ID card.

One day later...

"I found out that the man is named Huang Zhibing, 32 years old, is a supporting actor. He is a company owned by Hongxing Chen Yaoqing, which specializes in providing supporting services to various crews. He goes to various crews to make money every day and has no development prospects."

"This guy's target is his father. I don't know the specific reason, but it's just those, fraudulent insurance and inheritance." The woman shrugged and said.

"Are you sure the person is fine? You can't make mistakes in our business." The boss wearing glasses asked in a low voice.

"Certainly, I asked someone to ask his neighbor, and I saw him on the crew. I found several TV series and had his footage." The woman nodded and said.

"That's good, make a plan."
