Desperate Hacker

Chapter 540 Starlink Backdoor

Chen Qingfeng wants to build a Starlink receiver.

This thing is not difficult to get, especially in Malaysia.

Chen Qingfeng got one smoothly.

Then he used tools in his room to dismantle the device into eight pieces.

Wrapped under the shell are 4 layers of plates, the aluminum plate of the bottom shell, and the middle layer is a layer of PCB.

Above that is a honeycomb-shaped absorbing material and a layer of metal mesh.

Four layers of boards are stacked together.

Chen Qingfeng took the piece of PCB and slowly studied its rules.

The more I look at it, the more I am amazed.

According to the data, this PCB board integrates GPS, CPU, and phased array radar chips.

Can you provide network services with a delay of 20 milliseconds?

You can use this thing to play games and surf the Internet.

Behind the receiver is a bracket consisting of two motors.

Chen Qingfeng knew that this microwave receiver needed to be adjusted to align with the satellite. However, considering the size of the receiver, Chen Qingfeng felt that it was a miracle that this thing could operate reliably.

Extending upward from the receiving surface of the satellite receiver, the coverage range is probably only enough for a high-speed satellite to pass by for a short period of time.

In other words, the entire network is in a process of constant connection and disconnection, disconnection and connection.

It sounds very similar to the communication method of mobile phones.

It's just that the mobile phone is constantly switching to nearby base stations.

Starlink is constantly exchanging with satellites and communicating with different satellites.

Chen Qingfeng studied it for a while.

It seems like there is no good way to do this.

If there really was a good way, the Russians wouldn't have such a headache.

However, although there is nothing you can do about the front part, there is a network port connection at the rear of the receiver.

What if the information is obtained directly from the network cable?

Chen Qingfeng looked at the motor at the back, and then looked up the chip data.

Suddenly, a knowing smile appeared on his lips.

Then he turned the PCB board over and started to check the chip model.

Sure enough, among the semiconductor manufacturers supplying products, there are manufacturers with vulnerabilities that Chen Qingfeng once exploited.

Things are much simpler now.

To put it simply, this thing needs to call a series of programs when it is turned on.

For example, the program that calls the motor and adjusts the posture. For example, load other programs, such as programs for retrieving satellites and detecting surrounding objects.

These things can all be used.

The premise is that you must find an external device and load the program into it.

Chen Qingfeng thought for a while and decided to ask Luo Chenghui's opinion.

"Lao Luo! Let me ask, there are two options. One solution is to find the network cable they use to connect to the training close to the inside, and then invade their system during the disconnection process! There is also a solution, you need to install a small device in That satellite receiver, but you have to turn them back on again, which option do you think is easier?"

"Wait a minute, boss, I don't understand!"

"Okay, let me say it again, one solution is that you need to find the wireless WiFi they connect to the network cable, and then find a way to hack in!"

"Boss, this is impossible. They put the equipment outside and the house is heavily guarded!"

"Then there is a second option. Let me teach you a way. You go and see if you can purchase the corresponding thing in the electronic market over there, and then I will tell you how to do it. Connect that thing to that device, and then Find a way to turn him off for a few seconds and then turn him back on!"

"Boss, it goes without saying! The latter method may be more practical!"

"Why? Is the risk factor high? If it is too dangerous, I will think of other ways!" "I am more confident about the second option! They put the equipment in an open place. I have observed it and you can find it. The locals disguised themselves as shepherds and approached the location where the antenna was placed! Don’t be afraid of disturbing the grass!”

"Are you sure?"

"some!"

Luo Chenghui answered questions raised by Chen Qingfeng on the phone.

Now Chen Qingfeng felt confident.

The thing he designed is very simple. To put it simply, it is a bit like a switch.

After the network cable at the interface is connected, it needs to be transferred through his switch and then to another network port.

All data passes through the switch and then is transferred to the new channel, but when the device is turned on, it will find a way to exploit the vulnerability of the chip to load the program into it!

In other words, the entire receiver will be added with a piece of code written by Chen Qingfeng himself during the initialization stage.

Chen Qingfeng did what he said.

So he made a PCB himself and connected two network ports. The power supply can be powered by a battery, because only the initialization stage requires a weak current. And it only takes a moment.

Chen Qingfeng experimented with the new link receiver he had assembled.

The program did not run successfully at first.

Chen Qingfeng checked it and found that there was a pointer pointing to the wrong position.

So he readjusted the code.

Then, it took me an entire afternoon to get this thing out.

"Luo Chenghui is still waiting for news from Chen Qingfeng. But he received a drawing, as well as the purchased chip model and components!"

This left Luo Chenghui a little confused.

But Chen Qingfeng's call came quickly. He told him the model of the chip and what he needed to purchase. Then he asked Luo Shenghui to ask those businessmen in the country in the past to see if they could get these things together.

Through his last rescue, Lao Luo had become familiar with the Wenzhou businessmen who were making a living in Africa.

He sent these things to the other party via WeChat.

Of course it is distributed.

Soon a boss said he had a way to get the stuff.

Luo Chenghui didn't waste any time and drove away from the camp.

After he found the other party, he quickly gathered all the components after repeated confirmations.

"Boss Luo! What do you want these for?"

"Nothing! The signal there is not good, let's get a signal booster!"

"Do you want to make it yourself? Do you want it? Try our switch here. It is newly shipped from China and is far ahead!"

"Forget it! Let's talk next time. My friend told me that this method works well. I'll go back and try it first..."

"Okay! If you need anything, contact me again. Just give me a call and I'll send it to you!"

"You get busy first!"

Luo Chenghui brought the things back, then took out the soldering iron and began to piece them together.

The circuit diagram designed by Chen Qingfeng was not difficult, so Luo Chenghui quickly put the components together without much effort.

Then he connected the original to the computer, and Chen Qingfeng taught him how to set up the program.

Quickly look at the correct information output by the interface. Chen Qingfeng knew that this thing should be completed.
