Reborn Ace Hack

Returning to the room where the two of them were staying, Xiao Yuan saw that Capa was still debugging the equipment and stood at the door of the room watching him busy.

"Capa, hurry up." Jiang Hua urged.

"It'll be ready soon, just wait for ten more minutes," Kapersky said without looking back.

"Tiff, please introduce to Xiao Yuan what these devices are used for." Jiang Hua ordered when he saw Tiff sitting there doing nothing.

Tiff stood up from her seat, and when Xiao Yuan walked to her side, she said: "According to the information Jiang Hua brought, the satellite you want to invade this time is a STE011 digital television broadcast produced by the American MSTE company.

satellite."

Speaking of invasion, Tiff glanced at Xiao Yuan and asked: "Are you really sure you want to invade a satellite?"

"Intrusion is not the purpose, my purpose is to obtain the source of the fighting arena video signal." Xiao Yuan said.

"Okay." Tiff shrugged and continued, "Invading a satellite that may only have some computer hardware chips and an embedded system responsible for the normal operation of these chips is not an easy task, and the probability of failure is far higher.

Far greater than the probability of success, you must first understand this."

"Of course I know this, you go ahead." Xiao Yuan nodded.

"Okay then." Tiff said, "If you want to invade a satellite, do you understand the basic process?"

"Of course I know this." Xiao Yuan said with a slight smile. He knew that Tiff actually didn't have much confidence in him, so he asked such a series of questions, and he noticed that Tiff was asking him these questions.

At this time, Kaspersky, who was debugging the equipment with his head down, was also listening with his ears pricked up.

"Can you tell me, let me see if the equipment we have prepared is enough." After hearing Xiao Yuan's answer, Kaspersky interjected.

"Strictly speaking, what we want to do is not to actually invade a satellite, because a real invasion requires gaining control of the satellite, and we don't need that much authority. We only need to obtain what we need from the satellite.

Just the video source information is enough," Xiao Yuan said.

After saying this, Xiao Yuan saw that neither Kaspersky nor Tiff had any intention to answer, and even Jiang Hua was listening, so he continued: "First of all, we need a satellite signal receiver to receive the corresponding signal from the satellite.

The video relay information is then signal demodulated through the demodulator, from which the video data stream and control information are separately processed.

information data flow, and then we analyze the control information flow to obtain the control protocol of the satellite. Through the control protocol, control data is transmitted to the satellite so that it can feed back to us the source address information of the band occupied by the video information of the fighting arena. Of course, here

, we also need a radio frequency information transmitter to work with it, that’s about it.”

Tiff and Kapersky looked at each other. Although neither commented on Xiao Yuan's words, judging from their expressions, they were still very satisfied with Xiao Yuan's answer.

"How's it going? My friend said it right, right?" Jiang Hua asked happily.

"Yes, the process is the same as we expected. It seems that we don't need to prepare additional equipment." Kaspersky said.

"Then hurry up and don't waste time." Jiang Hua said.

"Okay, okay." Kapersky quickly lowered his head and started working, and the movements of his hands sped up a lot.

Tiff introduced Xiao Yuan one by one to the various instruments and equipment placed in the room. Among these equipment, the demodulators, satellite signal receivers, radio frequency transmitters, etc. he mentioned just now are all available.

And after the demodulator separates the signal, the control information flow can be transmitted to a computer in the room through a specialized device and supporting software. They can analyze the control signal on this computer and convert it

The analyzed results are sent to the radio frequency transmitter through the software for trial access to the satellite.

After listening to Tiff's introduction, Xiao Yuan breathed a sigh of relief. He was originally worried that the equipment Jiang Hua prepared for him was not suitable for his ideas, but now it seems that this kind of thinking is unnecessary.

Kapersky quickly debugged all the equipment, then stood up, stretched, and said, "It's done, we can start work right away."

"I suddenly had an idea." Xiao Yuan suddenly thought of a shortcut and said.

"What do you think?" Jiang Hua asked.

"Can we get the detailed design information of ste011 from mste company? In that case, we don't need to test and analyze the satellite control protocol. We must know that it is not easy to reversely parse a protocol from the data stream. Even

The probability of failure will exceed the probability of success," Xiao Yuan said.

"Satellite design information is definitely top secret at MSTE. I think it is not much easier to obtain than when we analyze the satellite control protocol," Capa said.

"How can you know without trying? As long as their data is stored on the Internet, nothing is impossible. Is their server more secure than the Pentagon's server?" Xiao Yuan said.

"That's not true. Have you ever hacked into the Pentagon's server?" Kapersky waved his hand and said with his eyes shining.

"Haha, that's just an analogy. It's not like I have nothing to do. I want the FBI to invite me to tea. Why invade the Pentagon?" Xiao Yuan waved his hand and categorically denied Kaspersky's speculation.

"It turned out to be a metaphor. I thought you had invaded the Pentagon." Capa said with some disappointment.

"Capa, let's not talk about the Pentagon's affairs. Let me ask you. Is it okay to leave the satellite protocol analysis to you and Tiff?" Jiang Hua asked.

"No problem." Tiff nodded.

"No problem, Tiff and I have been partners for a long time." Kaspersky also said.

"Since there is no problem, let's divide the work. The two of you are responsible for analyzing the satellite agreement. Xiao Yuan, you will be responsible for obtaining the detailed information of the satellite from MSTE Company." Jiang Hua said.

"Let's arrange it this way. I need a connected computer, preferably a Linux system." Xiao Yuan said.

"Then you can use this one. It is installed with feonix, a distribution that is currently very popular among hackers. I wonder if it suits you?" Kaspersky said.

"Feonix, haha, it's agreeable, it's so agreeable." Xiao Yuan laughed and said, even Jiang Hua laughed, but neither of them explained anything, but their laughter made Kappa a little confused.

mind.

Xiao Yuan sat next to the computer, turned on the computer, and looked at the familiar accounts in the feonix system. "Xiao Yuan said. Account?" Kapersky frowned and said.

He told Xiao Yuan the account password, and then watched Xiao Yuan log in to the system with his account, and operate it skillfully, even more proficient than him, and then left with peace of mind. He connected to the Xuan Nie open source community in China,

After downloading some software packages and development kit source codes, after compiling them in the system, they began to write some tools they needed. At this time, Kapasky and Tiff also began to receive video data streams from the satellite and separated them.

Satellite control information, and then began to analyze those control data flows.
