The distance between the Jinhai Entertainment Club and the S is not far, because it is close to the early morning, so there is no traffic jam on the street, and it takes more than 20 minutes to take a taxi, and Zhang Yang has arrived near Jinhai Entertainment. The location of Jinhai Entertainment is very prosperous, its own building is not high, just a thirteen-story comprehensive large club, but there are many skyscrapers around Jinhai Entertainment.

The location of Jinhai Entertainment belongs to the place where H City is developed, the green environment here is relatively good, not far from Jinhai Entertainment is an open street park, the park is not big, and there are not many people in the second half of the night. Finding a chair to sit down, Zhang Yang quickly turned on the computer and quickly connected to Satellite 1.

This is the first time Zhang Yang has checked satellite images at night, and the weather is good today, even at night, under the bright street lights, Zhang Yang even found himself.

After experimenting with the satellite, Zhang Yang directly used the resources of the satellite to re-enter the server of Telecom, and after finding the approximate location of the network cable box nearby, Zhang Yang quickly used the satellite's accurate positioning system to easily find it in a place in the street park.

There are several cable boxes in this vicinity, in 04 years, the construction of broadband is still a little chaotic, even in the internal system of telecommunications, the description of its lines is not too detailed, only to find the specific cable conversion box, find the number on it, in order to query something in the system.

Entering the number on the cable box into the telecommunications system, it took a few minutes for Zhang Yang to find what he wanted. A large entertainment club like Jinhai Entertainment must have a monitoring system, Zhang Yang didn't want to hack the monitoring system, he just wanted to find the security system of Jinhai Entertainment.

The security system here is not network security, but refers to the emergency security system of the club, including the escape system after the occurrence of fire and other accidents. The modernization process of H City is still good, although it cannot be compared with the management system of the first-tier cities in the United States, but some of the systems have already begun to be built.

For example, the fire protection system will be connected to the city fire brigade, once there is a fire in a place, the fire brigade will appear an alarm, someone will immediately confirm the situation, if the fire is relatively large, the fire brigade will quickly send out the police. These systems are also network systems, the difference is that they are not quite the same as ordinary civilian networks, and they are relatively readable.

Just when Zhang Yang had just hacked into the security system, there was a sudden alarm sound of "Didi" on his laptop, Zhang Yang was stunned for a moment, and the system issued an alarm, only the firewall and some security policies have been triggered.

didn't care about his own affairs, Zhang Yang directly switched the page out and quickly began to check it. Because Zhang Yang is still using Satellite 1, his notebook is just a tool to assist in acceptance, and Zhang Yang can now call up quite a lot of server resources. Soon Zhang Yang found the reason for the alarm, it was not that his broiler was attacked, nor that the honeypot he had placed on some servers was triggered, the alarm was sent from a mobile server.

After Zhang Yang modified his mobile phone number in the mobile system, he set up a small program at that time, this program is not a virus, it can only be said to be a security policy, as long as the mobile server or system has behavior against his mobile phone account, this thing will send an alert.

At the beginning of the facility, Zhang Yang was afraid that when he was upgrading the system, the system would self-check that there was a problem with his mobile phone account, and set it up, but when Zhang Yang didn't expect it, the prompt just now was not to move the upgrade system, but to manage the management authority of a server, and his account was locked and detected by frequency.

To put it plainly, someone is tapping his phone! When many people call mobile phones, they have encountered the problem of mobile phone serial signal, each person's mobile phone number is unique, and in the mobile system, the system host will give each mobile phone number a unique signal frequency.

When you make a call, the mobile phone you dial will send a signal to the system, and then the system will give you a communication connection, theoretically, everyone's call is a single line, of course, this is theoretical, in fact, there is no absolute surname for anything.

As early as in his previous life, Zhang Yang knew that in fact, mobile phones can be easily tapped, whether they are illegal or "legal", the so-called legal means that the accounts inside the mobile system are eavesdropping. For the system as a whole, it is a "legal act".

But this is not just as simple as eavesdropping, Zhang Yang was shocked, quickly took out his mobile phone and turned it off, then took out the battery, and then stuffed it back into his pocket.

"Someone stalking themselves? Who is it? Zhang Yang was a little inexplicable, and carefully used the computer to enter the mobile system, Zhang Yang first thoroughly checked the entire mobile system, and confirmed that there was no trace of anyone monitoring, and Zhang Yang began to check the information about his mobile phone number.

Just when Zhang Yang was about to call his mobile phone number information, Zhang Yang suddenly found that a data stream was also calling Zhang Yang's mobile phone number information, Zhang Yang quickly withdrew his hands and feet, hesitated, Zhang Yang released the infected worm, and after locking this data stream, Zhang Yang immediately sneaked up.

He has already discovered that this data stream is a mobile system logged in through a special account, and this special account is not the super administrator of the system, how to say it, it should be said that it is a backdoor account! But this backdoor is not like Zhang Yang, who secretly hacked the mobile system and then opened the back door, but left this backdoor at the beginning of the system's creation.

In other words, this backdoor was left by the creator of this system, the ability to infect insects is very powerful, and this data stream does not hide its traces, and an IP soon appears on the flamboyant computer.

After switching the screen, Zhang Yang directly searched for the unit to which this IP belonged in the telecom server, and when the three words of the Public Security Bureau appeared on the screen, Zhang Yang was stunned for a moment, and then he suddenly realized. A few pieces of information turned in his mind, and Zhang Yang immediately understood that someone must be investigating him.

has the ability to investigate himself through the Public Security Bureau, Zhang Yang quickly excluded Pan Wenlong and others. This account is very unusual, this kind of account that can log in to the mobile system and act conveniently has been seen before, and only the intelligence department has it. This kind of thing exists in the system of any telecommunications company, not only in China, but also in other countries.

Whether it is in China or in the United States, which flaunts freedom and open cooking, the so-called freedom and open cooking are all relative. In any country, all international calls must be detected by the country's security system, which will have keywords in it, and as long as these keywords are involved in your call, the system will immediately record and record your call.

And the keywords are also hierarchical, if it involves some classified keywords, once you say it, not only will your call be recorded, but your conversation will quickly and directly go to the security personnel responsible for monitoring. In China, there are more than 100,000 people under the national security department who are responsible for this work every year.

And in the United States, the NSA, that is, the National Security Agency, the whole department is specifically responsible for this. The other party can use such an account, it should not be an ordinary policeman, and it is bound to get the tacit approval of some departments.

"Could it be that Guoan found out his head so quickly?" Zhang Yang touched his bare chin and said to himself, only this possibility can be explained, Zhang Yang has never doubted the ability of the national intelligence department, it is not very difficult to find him, if it is the national security using the public security in H City to investigate, Zhang Yang is relieved.

He is not afraid of the investigation of the Internet Supervision Bureau, Zhang Yang is afraid that he will be targeted by other hackers, as for the Internet Supervision Bureau, he is now a "good citizen", even if they test, they will be restrained, and will not use all means, besides, to deal with the Internet Supervision or national security, Zhang Yang has long been confident.

After carefully observing his account information again, the other party had already left, and Zhang Yang relaxed. Both the police and the national security have a positioning system, which can quickly locate the location of the caller through the mobile phone signal and then connect to the satellite, which takes about a few minutes, but if you unplug the phone battery, then they will not be able to find you.

Shutdown is not good, shutdown is just the system turned off, in fact, the signal receiver inside the mobile phone is still in working condition, and professional tools can still detect this information. Exiting the mobile system, Zhang Yang switched back to the satellite, and when he looked at the monitoring screen on the satellite, Zhang Yang couldn't help but "lean" on.

He didn't spend too much time, but it was more than twenty minutes, but he didn't expect Pan Wenlong to come out of Jinhai Entertainment, Zhang Yang was just about to find Pan Wenlong through Jinhai's internal monitoring system, and then turn on the fire system to sprinkle water for him to play first.

Unexpectedly, he drove away, looked at the direction of Pan Wenlong's car, Zhang Yang knew that he was ready to go back to where he lived, Pan Wenlong did not live at home, Pan Hu bought him a villa of more than 200 square meters in Xinjiangyuan, which is very close to S University, and Pan Wenlong usually lives there.

Closing the notebook, Zhang Yang walked directly to the street and stopped a taxi, "Master, go to Xinjiangyuan." Zhang Yang said quickly. Now that the network supervisor has begun to investigate him, if you want to knock on the black bricks, you have to hurry, and if you want to do it in the future, you won't have a chance.
