The development of Skynet is completed, and Mo Hui first needs to figure out the data source of municipal monitoring, which Mo Hui has no reliable social relationship to solve, so he plans to solve it through technical means. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Municipal monitoring actually belongs to the private network of the police, although it is not physically isolated like a military network, but the protection intensity in the middle is very high, and if it is accidentally discovered, the size is also a thing, to the small enough to detain, to the large enough to sentence.

It is precisely because of a bit of a ban that Mo Hui intends to use a relatively hidden method. Mo Hui prepared for this for a long time, specially bought a lot of integrated circuit modules, and finally after all the materials were ready, a portable small wireless signal receiver was assembled.

This is a high-sensitivity 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, all digital devices, when they are not deliberately equipped with radio shielding systems, will emit wireless signals all the time.

For example, a home computer, as long as it is turned on, the current starts to move in its cable, motherboard, hard disk, and monitor, and various signal waves will be generated. When the computer is connected to the Internet, as long as there is an electric current passing through the network cable, it will also emit signal waves. By collecting these emitted signal waves, it is actually possible to reverse interpret the information carried by the current itself. The receiver that Mo Hui assembled was actually used for this.

Mo Hui installed all kinds of algorithm software on the ultrabook, debugged the signal receiver, and then began to locate the network cable of the house next door. When the receiver starts to work, a long row of signal sources appear in the list, these signal sources are distributed in a three-dimensional lattice pattern, and what Mo Hui needs to do is to distinguish the signal of the neighbor's network cable next door in the signal source like a star.

This is not difficult in itself, Mo Hui quickly selected the neighbor's network cable signal, and after clicking, other signal sources were filtered out, and the network cable signal was enhanced and amplified, and began to analyze.

At this time, Mo Hui can basically watch the Internet records of his neighbors in real time, and through the auxiliary software of the ultrabook, he found data packets from five different MAC addresses in the network cable transmission data.

After further analysis, it can be found that there are two mobile phones, a laptop, a desktop, and a TV Internet device.

Clicking on the data package of the notebook, the screen content of the neighbor's notebook immediately appeared in front of Mo Hui, and it seemed that the neighbor was watching a movie online. The current mode is very much like turning on remote control, except that Mo Hui can't control his neighbor's laptop, and the neighbor doesn't know it.

Good performance!

Mo Hui put away the receiver with satisfaction and began to look for the key nodes of the municipal monitoring network data transmission, and it is not difficult to find a suitable transmission node. First of all, it is necessary to find out which department is in charge of these monitoring data, and where is the location of this department.

This is not difficult to get, because it is not a secret in itself, Mo called Li Gang's phone back, casually found a topic to talk about for a while, and then casually asked a few words, and the key information was in hand.

The next day, Mo Hui drove the car and set off with a signal receiver, and soon he came to the city traffic management center, where all the municipal traffic monitoring data was finally gathered.

The traffic management center is a high-rise building of more than ten floors, Mo Hui turned on the receiver, drove the car and began to circle around the traffic management center, he drove very slowly, not much faster than walking, while driving, while rotating the antenna of the signal receiver, looking for targets in many wireless signals.

The target is actually not difficult to find, because it must have a key feature, that is, the big data flow, the city's monitoring data is gathered here, it is conceivable, nearly 100,000 monitoring probes, they are thinking about the traffic management center all the time to send real-time data, even if a probe occupies 50k of bandwidth, all of these probes add up to nearly 5t of bandwidth.

Such a huge data stream must be as eye-catching as a searchlight in the dark night in a large number of wireless signals, so Mo Hui only circled around the traffic management center twice, and locked the signal source responsible for the transmission of these signals.

Once the signal source is locked, a large amount of monitoring data begins to swarm in, but fortunately, the ultrabook has surpassed the scope of human technology, under such a massive amount of data input, the ultrabook is not alarmed, there is no abnormal reaction at all, and even the lag and delay can not be seen.

Massive amounts of data are input in, constantly parsed by Ultrabook, and then classified and stored, and classified into different files according to different MAC addresses and different signal sources. Nearly 100,000 video files are automatically generated, and they begin to grow slowly over time~~~

Step 1 is complete!

The preliminary docking of data is normal, but it is not enough to rely on these alone, these are just real-time data, which will be transmitted 24 hours a day all year round.

It's impossible for Mo Hui to keep an eye on it all the time, and it's unrealistic to always let the ultrabook download data here, so Mo Hui has to solve this problem.

The solution is very simple, Mo Hui chooses to download the historical monitoring data, and then come here regularly to update the latest data, so as long as the continuity of the monitoring data is ensured, and there is no missing in the middle.

Under normal circumstances, it is enough for Skynet to analyze historical data, and when real-time data is really needed, Mo Hui can download it in real time with Chaoji.

After verifying that there were no problems with the download, Mo Hui began to convert the signal source and began to look for a place to store the monitoring data. This data source is a bit more difficult to find. The whole building is full of signal sources, and the space between the various sources is very small, and finding a target in so many sources is a test of luck and eyesight.

Don't go back and look for a server group or a disk array, which is where all the monitoring data is stored. Although it is not easy to find, Mo Hui specifically looked for those signal sources arranged regularly in the shape of a matrix, and quickly found a few suspected signal sources.

Now that it's been found, the next thing needs to be solved next time, because Mo Hui is just actually testing the performance of the receiver now to see if he can download the health data. If you want to download historical data from the storage device, you need to interact with information, and a simple receiver will not be, I am afraid that you will have to find another way to hack into this private network, send instructions to the storage device, read the historical data, and then achieve the purpose.
