Chapter 53 Stealing Monitoring Data
The development of Skynet has been completed. Mo Hui first needs to solve the data source of municipal monitoring. Mo Hui has no reliable social relations that can be solved by this source, so he plans to solve it through technical means.
Municipal surveillance actually belongs to the police's private network. Although it is not physically isolated like a military network, the protection strength in the middle is very high. If you are accidentally discovered, it is also a big deal. It is enough to be detained in the smallest, and it is enough to be sentenced in the largeest.
It is precisely because it is a bit banned that Mo Hui intends to use a relatively hidden method. Mo Hui has prepared for this for a long time and specially bought a lot of integrated circuit modules. Finally, after all the materials are all, a portable small wireless signal receiver is assembled.
This is a highly sensitive wireless receiving antenna, which can selectively receive wireless signals from specific frequency bands and specific signal sources with the help of software.
Mo Hui’s choice is based on the most basic reality, that is, when all digital devices do not deliberately install radio shielding systems, they will emit wireless signals to the outside at all times.
For example, when a home computer is turned on, the current starts to move in its cable, motherboard, hard disk, and monitor, and various signal waves will be generated and emitted. When this computer is connected to the network, as long as current passes through the network cable, signal waves will also be emitted. By collecting these emitted signal waves, the information carried by the current itself can be completely reversely parsed out. The receiver assembled by the assembled is actually used for this.
Mo Hui installed various algorithm software on the ultrabook, debugged the signal receiver, and then began to locate the network cables of the next door. When the receiver started to work formally, a long row of signal sources appeared in the list, and these signal sources were distributed in three-dimensional dot matrix. What Mo Hui needed to do was to distinguish the signals of the network cables of the next door neighbor's home in a signal source like stars.
This is not difficult in itself. Mo Hui quickly selected the neighbor's network cable signal. After clicking, other signal sources were filtered out, the network cable signal was enhanced and amplified, and the analysis began.
At this time, Mo Hui can basically watch the neighbor's Internet records in real time. Through the auxiliary software of the ultrabook, data packets from five different Mac addresses were found in the network transmission data.
After further analysis, we can find that there are two mobile phones, a laptop, a desktop, and a TV Internet access device.
Click the data packet of the notebook, and the screen content of the neighbor's notebook immediately appeared in front of Mo Hui. It seemed that the neighbor was watching a movie online. The current mode is very similar to the remote control turned on, but Mo Hui could not control the neighbor's notebook, and the neighbor was unaware of it.
Good performance!
Mo Hui put away the receiver with satisfaction and began to look for key nodes for data transmission of municipal monitoring networks. It is actually not difficult to find the right transmission node. First, just figure out which department is responsible for these monitoring data, and where the department is located.
This is not difficult to find, because it is not a secret itself. Don’t call Li Gang back, find a topic to chat for a while, then ask a few questions inadvertently, and then get the key information.
The next day, Mo Hui drove the car and set off with a signal receiver. Soon he arrived at the city traffic management center, where all the municipal traffic monitoring data finally gathered.
The Traffic Management Center is a tall building with a height of more than ten floors. Mo Hui turned on the receiver and drove the car to circle around the traffic management center. He drove very slowly, not much faster than walking. While driving, he rotated the antenna of the signal receiver and looked for targets in many wireless signals.
The goal is actually not difficult to find, because it must have a key feature, that is, the big data flow, and the monitoring data of the whole city gathers here. You can imagine that there are nearly 100,000 monitoring probes, and they are thinking that the traffic management center is sending real-time data at every moment. Even if a probe occupies 50k of bandwidth, all of these probes have nearly 5t of bandwidth together.
Such a huge data stream must be as eye-catching as a searchlight in the dark night among many wireless signals, so Mo Hui only turned around the traffic management center twice and locked the signal source responsible for these signals.
Once the signal source is locked, a large amount of monitoring data begins to flock in. Fortunately, the ultrabook has surpassed the scope of human technology. With such a massive amount of data input, the ultrabook is calm and has no abnormal reactions at all, and cannot even see lag and delays.
Massive data is input in, and is constantly parsed by the ultrabook, and then classified and stored. According to different mac addresses and different signal sources, they are classified into different files. Nearly 100,000 video files are automatically generated and they begin to grow slowly over time~~~
The first step is completed!
The initial data docking is normal, but it is not possible to rely on these alone. These are just real-time data and will be transmitted continuously 24 hours a year.
It is impossible for Mo Hui to keep staring here and always let the ultrabook download data here. This is unrealistic, so Mo Hui still has to solve this problem.
The solution is very simple. Don’t choose to download historical monitoring data, and then come here regularly to update the latest data. In this way, just ensure the continuity of the monitoring data and ensure that there is no missing in the middle.
Generally speaking, it is enough for Skynet to use historical data for analysis. When real-time data is really needed, Mo Hui will bring Super Origin to download it in real time.
After verification, there was no problem with the download. Mo Hui started to convert the signal source and began to find a place to store the monitoring data. It was relatively difficult to find this data source. The entire building was full of signal sources, and the spatial spacing of each signal source was still very small. Finding a target in such a large number of signal sources was a test of luck and vision.
This time, Mo Hui was looking for a server group or a disk array, which are the places where all monitoring data are stored. Although it is not easy to find, Mo Hui specifically looks for regularized signal sources, in matrix shapes, and quickly found several suspected signal sources.
