A War Between Spies

Eavesdropping, camera, this is a must-have item for spies. It is not a special equipment. Needless to say, even if the water organization is poor, it must be.

But after Yang Yi put the surveillance equipment that was put on the table on the table, he couldn't help but take a shot at the table and said loudly: "You absolutely can't guess what I found!"

Xiao Yu saw Yang Yi, then she picked up the camera and said, "What did you find?"

Yang Yi sighed, and then he sighed: "Handle, Martin Howard's handle, he must obey the handle!"

Xiao Yu gave Yang Yi a white eye and said: "What is mysterious, what to sell, cut."

Kate pressed the play button of the recorder. Yang Yi’s eyes were fast, and he took the recorder. After turning it off, he looked serious and said: “I solemnly warn you that the contents may cause you. Resentment, so please consider carefully before you decide whether to listen to the content inside."

Xiao Yu is very surprised: "No, is Martin really a dog?"

Yang Yi took a moment, then he frowned. "What, you say it again?"

Xiao Yu was also a bit stunned, and then she said something awkward: "Hey, isn't it?"

Yang Yi cried and laughed, saying: "What are you thinking about in your mind?"

Xiao Yu suddenly became angry again. She looked at Yang Yi’s anger and said: “What is your mysterious secret, what is unspeakable.”

Xiao Yu grabbed the recorder and opened the play button, and the voice quickly spread. Soon, Xiao Yu said with a disdain: "What! Martin Howard is just gay."

Yang Yi is puzzled: "Just? Just?"

Kate is thoughtful: "Speaking of Martin Howard, although he is older, he is really handsome and very graceful."

Xiao Yu nodded: "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?"

"Look, there is no video."

Yang Yi couldn't help it, he said loudly: "Stop! Stop! Your focus is completely wrong? Turn it off! I can't stand it, turn it off right away!"

After grabbing the recorder and turning it off, Yang Yi’s heartache said: “What are you thinking about, can you be normal, can you? Can you!”

Xiao Yu disdains: "It's rare and strange."

Kate is also a handkerchief: "Yeah, is this the handle you said?"

Yang Yi quickly collapsed, and then he hated the words: "Forget it, it is my ability to withstand poor, now call the candy and Schultz."

No one is calling, candy and Schultz are already carrying the computer down.

Although she had an all-nighter, but the candy was not exhausted at all, she reversed the computer and placed it in front of Yang Yi. “It’s all done, there are thirty-two cameras on the outside, and there are a lot of internal surveillance cameras. Only seven, but all in a very critical position, and the fire evacuation diagram helped us figure out the key locations. The central computer processor of the Ministry of the Interior is on the third floor, where there are two cameras and two guards. In fact, there are thirty-six guards in the entire Ministry of Interior building, but there are only six night guards, two of which are in the monitoring room."

Schultz also put on his computer and smiled: "We can take over the monitoring at any time. Oh, some computers are equipped with cameras, so we have also taken a lot of images inside the office, which are all insensitive areas. But enough to build a complete 3D schematic, I and the White Howler used most of the night to make the 3D schematic, and by the way also outlined the patrol route of the night guard, the red line is."

Great, Tang Guo and Schultz's ability is better than Yang Yi's most optimistic prediction.

Yang Yi’s face was full of smiles. He nodded frequently, then he screamed: “How did you do that?”

Schultz shrugged: "That's just like that, like all hackers."

"I mean, how can the technical difficulties be solved? Is it impossible to connect to the Internet in a monitoring room?"

Tang Guo waved: "Yes, physical isolation, no connection to the network, but it is still possible to black into the monitoring network, because they use a system with loopholes, only need to connect a computer inside the Ministry of the Interior, you can control more The computer, then, if you have the opportunity, you can control the computer in the monitoring room. The monitoring of course requires a computer, and we can easily do it. There is no luck. This must be explained."

Yang Yi looked at Xiao Yu and looked at Kate again. Then they found that the two of them were also in a state of arrogance, so he knew that it was not only that they could not understand.

“I mean, how can you control the monitoring room computers that are not connected to the outside world?”

Schultz said seriously: "It's not without networking, it's just not connected to the outside world, but monitoring itself is a small closed network, as long as we can take over the computer..."

Tang Guo smiled and said: "They are not asking this. Let me explain, we use the sound, understand?"

"sound?"

"Yes, the basic principle is very simple~www.NovelMTL.com~ Using a computer with an audio or a built-in speaker to generate sound waves, it is an infrasound that the human ear can't hear, and then introduce the vibration frequency of the second to the data of the hard disk. Store the platter, find the right frequency, and generate a resonance effect, as an attack means, interfere with the hard disk until the hard disk is damaged and stop working."

Yang Yi touched his head and said; "So amazing?"

Schultz replaced Tang Guo for his commentary work. He laughed: "This is not magical. This is not a new technology. In 2008, the chief technology officer of Joyent Corporation of the United States publicly demonstrated this technology. I was only inspired. , based on this technology has been improved."

Tang Guo pointed to the computer and said: "When the guards find that the control computer of the monitoring room stops, they certainly need to be repaired. But when they restart and find that they are useless, they can only change one computer. What computer would you use? Is it a cumbersome desktop computer or a laptop that picks up and leaves? When they use a laptop instead of the original computer to control all the cameras, then our chances are coming, let this laptop establish WiFi. Connections, we control again remotely, so until they changed the computer, the monitoring system of the Ministry of Interior building was controlled by me and black lightning, it was as simple as that."

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

Yang Yi thought for a moment and said: "It seems to understand, then that means you are in charge of monitoring now, but after changing the computer, you can't do it right?"

Tang Guo’s handkerchief: “Please, think about the efficiency of the Ministry of the Interior. When they confirm that the computer is damaged, and apply for a computer for a report, how long do you think it will take?”

Yang Yi took a breath and said: "The desperate inefficiency of the Ministry of the Interior, you are right, that's it, so our chances have already come, that's it!"
