Chapter 346 That’s It!

Eavesdropping devices and cameras are essential supplies for spies. They are not special equipment at all. Needless to say, no matter how poor the organization is, they must have them.

But after Yang Yi put the useful surveillance equipment on the dining table, he couldn't help but slap the table and said loudly: "You will never guess what I discovered!"

Xiao Ran glanced at Yang Yi, then she picked up the camera and said, "What did you find?"

Yang Yi breathed a sigh of relief, and then he said in a deep voice: "The handle, Martin Howard's handle, the handle that he must obey!"

Xiao Ran rolled her eyes at Yang Yi and said, "Why are you pretending to be mysterious and selling off your secrets? That's right."

Kate pressed the play button of the recorder. Yang Yi, with quick eyes and quick hands, snatched the recorder, turned it off, and said in a serious voice: "I solemnly warn you that the content here may cause you disgusting, so please think carefully before you decide whether to listen to the content."

Xiao Ran was very surprised and said: "No way, is Martin really a dog lover?"

Yang Yi was stunned for a moment, then he frowned and said, "What, you say it again?"

Xiao Ran was also stunned for a moment, and then she said somewhat sarcastically: "Uh, isn't it?"

Yang Yi didn't know whether to laugh or cry, and said: "What are you thinking about?"

Xiao Ran suddenly became angry again. She looked at Yang Yi and said angrily: "What are you doing so mysteriously? What's so shameful about it?"

Xiao Ran grabbed the recorder and turned on the play button, and the sound came out quickly. Soon, Xiao Ran said with disdain: "What! Martin Howard is just gay."

Yang Yi said in confusion: "Just? Just?"

Kate said thoughtfully: "Speaking of which, although Martin Howard is a bit older, he is indeed handsome and very graceful."

Xiao Ran nodded and said: "Yes, the charm of a mature man."

Kate listened to the recording and nodded: "The voice is quite sexy."

"yes, I agree."

"Is his boyfriend handsome?"

"Take a look, isn't there a video?"

Yang Yi couldn't help it anymore, and he shouted: "Stop! Stop! Your focus is completely wrong, right? Turn it off! I can't stand it anymore, turn it off now!"

After grabbing the recorder and turning it off, Yang Yi said sadly: "What are you thinking about? Can you be normal? Can you? Can you!"

Xiao Ran said disdainfully: "It's rare but strange."

Kate also spread her hands and said: "Yes, is this what you said?"

Yang Yi was about to collapse, and then he said bitterly: "Forget it, just think that I can't bear it. Now call Candy and Schultz down."

No one needed to call, Candy and Schultz had already come down with their computers.

Although she stayed up all night, Candy didn't look tired at all. She turned the computer over and placed it in front of Yang Yi, saying: "It's all done. There are thirty-two cameras on the outside, and there are far fewer surveillance cameras on the inside. There are only seven, but they are all in very critical locations. In addition, the fire evacuation diagram helped us figure out the key locations. The central computer processor of the Ministry of Interior is on the third floor. There are two cameras and two guards there. , In fact, there are a total of thirty-six guards in the entire Ministry of the Interior building, but there are only six night shift guards, two of whom are in the control room."

Schultz also put on his computer and said with a smile: "We can take over the surveillance at any time. Oh, some computers have cameras, so we also captured a lot of images inside the office, which are all insensitive areas. But it was enough to create a complete 3D schematic diagram. Bai Roar and I spent most of the night making the 3D schematic diagram, and by the way, we also drew the patrol route of the night shift guard, which is the red line."

Great, Tang Guo and Schultz's abilities exceeded Yang Yi's most optimistic expectations.

Yang Yi had a smile on his face, he nodded frequently, and then he said loudly: "How did you do it?"

Schultz shrugged: "That's what all hackers do."

"I mean, how to solve the technical difficulties? It's impossible to connect to the Internet in a place like the monitoring room, right?"

Tang Guo waved his hand and said: "Yes, they are physically isolated and not connected to the Internet, but they can still hack into the surveillance network because the system they use has loopholes. They only need to connect to a computer in the Ministry of Interior building to control more Computer, and then if there is a chance, you can control the computer in the control room. Of course, monitoring requires a computer, but we did it easily, there is no luck, this must be explained."

Yang Yi looked at Xiao Ran and then at Kate, and then found that both of them were also confused, so he knew that he was not the only one who couldn't understand.

"I mean, how can you control the computers in the control room that are not connected to the outside world?"

Schultz said seriously: "It's not that there is no Internet, it's just that it's not connected to the outside world, but the surveillance itself is a small closed network. As long as we can take over the computer..."

Tang Guo smiled and said: "That's not what they asked. Let me explain. We use voices, do you understand?"

"sound?"

"Yes, the basic principle is very simple. Use a computer with a speaker or a built-in speaker to generate sound waves, which are infrasound waves that are inaudible to the human ear, and then introduce the subsound vibration frequency to the data storage disk of the hard disk to find the right Frequency, produces a resonance effect, and uses this as an attack method to interfere with the hard drive until the hard drive is damaged and stops working."

Yang Yi touched his head and said, "Is it so magical?"

Schultz replaced Tang Guo as the commentator. He smiled and said: "This is not magical, and it is not a new technology. In 2008, the chief technology officer of the American company Joyent publicly demonstrated this technology. I was just inspired. , it’s just an improvement based on this technology.”

Tang Guo pointed to the computer and said: "When the guards find that the control computer in the control room has stopped, of course they need to repair it, but when they restart it and find that it is useless, they can only change it to another computer. What computer will you use? Is it a bulky desktop computer or a laptop that you can pick up and go? When they use a laptop to replace the original computer to control all the cameras, then our opportunity will come to let this laptop establish WiFi Connect it and we control it remotely, so until they change the computers, the surveillance system in the Interior Department building is controlled by me and Black Lightning, it’s that simple.”

Kate looked at Yang Yi blankly and said, "Do you understand?"

Yang Yi thought for a while and said: "I seem to understand, so now you are in charge of monitoring, but it won't work after changing the computer, right?"

Tang Guo spread his hands and said, "Please, think about the work efficiency of the Ministry of Internal Affairs. How long do you think it will take for them to confirm that the computer is damaged and file a report to apply for a replacement computer?"

Yang Yi took a breath and said: "You are right about the hopeless inefficiency of the Ministry of Internal Affairs, that's it, so the opportunity for us to take action has come, that's it!"
