A successful hacker not only needs skillful technology, but also requires a wealth of knowledge to cooperate with multiple subjects, including mathematics, psychology, social engineering, linguistics, etc.

How to obtain unknown prepaid bearer mobile phone number through known room numbers?

The solution is not difficult!

Nan Lin Guiyi ordered Butler to start the independent inductive learning and judgment mode, and also ordered Butler to monitor Qin Yun and notify him immediately if Qin Yun comes upstairs.

Of course, if anyone else goes upstairs, you also need to notify you!

After making preparations, Nan Linguiyi started to typing on the keyboard. He first lifted the restrictions of the shadow system and entered the real system. Then, in the real system, he connected to the ACPs asynchronous parallel computing system.

Through the computing power of the ACPCS system, Nanlin Guiyi is centered on the Huagu Hotel in Datian District, and searches the surrounding mobile service base stations, including all base stations of five mobile service providers.

After Nanlin Guiyi's inspection, the base stations that borrowed doo by e-touching and o-touching were ruled out.

Therefore, Nanlin Guiyi only needs to detect base stations of the three major operators of doo, softbank and au. In fact, in Japan, it is basically the world of the three major operators, and the other two have their own operating focus.

After Nanlin Guiyi retrieved the base stations of the three major operators, their coverage area was displayed through shaded areas of different colors. The final intersection was naturally the Huagu Hotel.

After determining the base station signals of the three major operators, Nanlin Guiyi entered the guest check-in information record of Huagu Hotel and listed all the check-in personnel.

Then, based on the identity information of the occupants, return to the internal networks of the three major operators, and cross-compare the telephone numbers of the occupants.

After a while, a total of 79 occupants were retrieved, and the telephone number information of 67 personnel was found, of which twelve occupants failed to find the telephone number.

Among the twelve occupants who failed to find the phone number information, three of them were e-touch users. Naturally, the information could not be found within the database of the three major operators.

Nan Lin Guiyi gave up the three e-touching users, only three were missing, it didn’t matter!

Only the last nine users left, and the phone number is unknown. Although it is still impossible to determine the phone number of Dai A, the next work is already very simple!

The mobile service base station maintains a connection with the mobile phone. The so-called mobile phone signal is actually the connection signal between the mobile phone and the mobile service base station. Simply put, if you view it from the mobile service base station, you can find all the connection information.

With Huagu Hotel as the target scope, the mobile service base stations of the three major operators have accessed a total of 79 signals. Among them, three e-touch users borrowed the mobile service base station of Doo, and were still discovered by the mobile service base station of Doo.

Because there are nine prepaid bearer accounts, Nanlin Guiyi cannot judge whether it is in the nine numbers. He can only test one by one.

However, how to obtain test results?

The answer is very simple!

Nan Linguiyi quickly tapped on the keyboard, edited a text script, and asked Butler to simulate a natural language dialogue and communication based on the text script.

Butler's artificial intelligence level is indeed very powerful. In the simulation scenario, Nanlin Guiyi and Butler cannot tell that Butler is a computer program.

If Butler participates in the Turing test, it will be a completely easy and easy rhythm!

But Nanlin Guiyi knew that there were many artificial intelligence systems that could pass Turing tests, but no one participated. After all, about artificial intelligence systems, every technology company and every technology giant all hid the artificial intelligence system.

"Butler, let's start!" Nan Lin Guiyi ordered.

In Room 1808, Huagu Hotel, the telephone rang.

Dai Jia was browsing his laptop. When the room phone rang, Dai Jia's face changed slightly. He looked at the room phone vigilantly, and finally picked up the receiver of the room phone.

"Moshimosi?" Dai Jia took the initiative.

"Hello, sir, do you need room service?" Butler's simulated female voice was very delicate, and it had a kind of listening.

"No need!" Dai Jia said directly.

Butler continued, "Sir, we provide different room service, we can come to the door in person, and the prices are very reasonable. If you are not satisfied after visiting the door, you can ask for a replacement."

Dai Jia understood Butler's meaning. He thought about it for a moment and asked, "Can you change it if you are not satisfied? Let's say it first, my requirements are very high!"

Having just completed the difficult task of playing with the Kasai Police Station, Dai Jia was very proud and decided to indulge himself. After all, Dai Jia thought that the Kasai Police Station could not catch him at all.

Otherwise, how could Dai Jia book a flight tomorrow?

"Please rest assured, sir, if you are not satisfied with the door-to-door service service we arranged, you can ask for a replacement. sir, do you need door-to-door service service?" Butler asked again in a charming voice.

"What price?" Dai Jia asked back.

Butler began to explain to Fa Jia, including different ages, different nationalities, different cup numbers, and different prices.

On the other hand, when Butler was communicating with Dai Jia, Nanlin Guiyi was not idle. He controlled the mobile service base stations of the three major operators and sent text messages to nine prepaid bearer phone numbers in turn.

The content of the short message is very simple, it is just a standard reminder message from mobile communication service providers and will not arouse suspicion.

When Butler and Dai Jia were nearly a minute in the conversation, Nan Lin Guiyi, who was in the Physical Evidence Technology Laboratory of the Kasai Police Department, suddenly smiled.

Because, after Nanlin Guiyi sent the text message again, Butler reminded Nanlin Guiyi that the system had collected the prompt sound of the text message through the telephone receiver in Room 1808 of the Huagu Hotel.

Dai Jia’s phone number, confirm!

After Nanlin Yiyi confirmed Dai Jia's phone number, Butler and Dai Jia also ended their communication. In fact, Butler guided him to end. Dai Jia was not satisfied with the price and hung up the phone.

However, Dai Jia didn't know that when he was talking to Butler, the text message ringtone sent by his mobile phone had already made Nan Lin Guiyi know his mobile phone number.

Nanlin Guiyi only sends a text message to one prepaid bearer number at a time. As long as Butler collects the message ringtone, it will prove that the number is from the armor.

"Butler, have you learned this method?" Nan Lin Guiyi asked.
