There is a famous saying in the hacking world: There is no absolutely safe system in the world!

The same is true.

For example, the physical isolation network, known as a hacker nemesis, should look like an absolutely secure system, right?

After all, physically isolating the network may also be installed with wireless communication modules and thus controlled remotely.

But what is currently in front of Nan Linguiyi is a dead end.

Physical isolation of the network, coupled with the configuration of the Faraday cage, not only isolates the physical network, but also the wireless network. How can this situation invade?

Unless you go in the real world and then get in touch with the internal network!

But how to get in the real world?

The security defense of Putian Machinery Factory is very powerful, with no dead corners, security patrol personnel with live ammunition, automatic weapon systems connected to the Internet of Things, and even infrared detection systems.

If Nan Linguiyi had not done the security monitoring system, automatic weapon system, and possible infrared detection system, etc., just by breaking into the Putian Machinery Factory with the three people from the Iron Gate, they would kneel in minutes and would be captured even if they did not die.

However, the problem returns to the origin.

The security monitoring system of the Putian Machinery Factory is a physically isolated internal closed network. In addition, the Putian Machinery Factory is protected by a Faraday cage, so even the wireless network cannot invade it. How can Nanlin Guiyi invade the security monitoring system?

Whether it is a real intrusion or a network intrusion, the road has been blocked.

Dead is a dead end!

Nan Lin Guiyi explained his analysis and finally said, "Iron Sect, have you not investigated the target before you take action? With the situation of the target, we have no chance at all."

Tiemen laughed, "Please rest assured, Mr. Lin, we have a way to break the deadlock. Your analysis is very correct. If the situation is normal, we will definitely not be able to break the deadlock, but we have a way to break the unconventional method. Wait for a moment, Mr. Lin, there are more than ten minutes left before we can connect with the target's internal network."

"Oh? What do you guys do?" Nan Linguiyi asked, "I need to keep an eye on the situation at all times to deal with unexpected situations."

Tiemen replied affirmatively, "Wait a moment, we will arrange a few webcams right away."

A few minutes later, Nanlin Guiyi detected the webcam through the signal repeater. Tiemen was also in the encrypted voice communication channel and responded: "Mr. Lin, you should be able to connect to the webcam, right?"

"Yes." Nan Lin Guiyi responded. Through the webcam, Nan Lin Guiyi observed Putian Machinery Factory again. This factory is worthy of being a supporting facility for the nuclear power plant. The safety defense level is too high, and it completely formed a dead end.

According to Nanlin Guiyi's judgment, it is impossible to invade the Putian Machinery Factory unless it is a strong attack.

No!

There is another possibility

To quote the theory of the hacker community, no matter how strong the defense system is, it is very fragile inside.

The external defense of Putian Machinery Factory has indeed reached a dead end. But what if it collapses from the inside? For example, Mr. Song bribed the personnel inside Putian Machinery Factory?

Nan Lin Guiyi considered this situation. If this was the case, perhaps the dead end could be solved.

As time approached seven o'clock every minute, Nan Lin Guiyi waited patiently. At 6:59, Tiemen issued a reminder, "Mr. Lin, there is one minute left, we can connect to the target's internal network. Please note, Mr. Lin, we only have three minutes. If you have not completed the invasion within three minutes, our actions will fail."

"Is it only three minutes?" Nan Lin Guiyi asked confirmation.

"Yes, it's only three minutes. Our inside line only has three minutes. Because there is also security patrol inside the target. We need to complete the intrusion within three minutes, control the security monitoring system, and completely hide the external network nodes set by the target." Tiemen explained in detail.

Nan Lin Guiyi sighed in his heart, it was indeed a way to cooperate with the inside and outside!

A dead end will also collapse from the inside!

Through the webcam, Nan Linguiyi saw the iron gate holding a metal rod and passing through the steel block protecting the Putian Machinery Factory. At the top of the metal rod, an I-shaped antenna popped up.

Tiemen explained, "This is a directional signal antenna. Our inside line will also use a directional antenna to send signals to us. Mr. Lin, ready to start the invasion operation. Once the signal is connected, please do not waste any second."

Nan Lin Guiyi affirmed, "I know."

At exactly seven o'clock.

Nanlin Guiyi discovered that the directional antenna had a connection signal through the satellite signal connector. He did not hesitate at all and immediately used the directional signal antenna to reverse trace the source.

The reverse traceability work was very smooth. Nanlin Guiyi discovered the internal network of the Putian Machinery Factory along the connection signal of the directional antenna. Because the signal of the directional antenna is directly extended by the internal network, Nanlin Guiyi does not need to spend time invading and enter it directly.

It only takes a little time to seize the permissions of the security monitoring system, the permissions of the Internet of Things management system, and the server permissions of the internal network.

But is it that a mere internal network is still a multi-protected internal network, and is it that it expects its server to be powerful? People have never considered the problem of being invaded!

In just fifteen seconds, Nanlin Guiyi obtained permissions to the security monitoring system. After a few seconds, Butler assisted Nanlin Guiyi to obtain server permissions on the internal network, and then naturally obtained control permissions from the Internet of Things.

The whole process took no more than half a minute!

"Iron Gate, I have obtained all the permissions. What are the characteristics of your inside line?" Nan Lin Guiyi asked Iron Gate. In fact, Nan Lin Guiyi had discovered a suspicious target through the security monitoring system.

It was a man in a white coat. He connected his mobile phone to the network line of the security monitoring system, and used aluminum metal tubes to make a tool similar to a directional antenna.

Tiemen was extremely surprised!

Because Mr. Song also has senior hackers. According to the other party's assessment, it takes at least two minutes of intrusion, not including unexpected situations. It's only less than a minute now, right?

Although surprised, Tiemen still responded calmly to Nanlin Guiyi. The situation described by Tiemen is the same as the suspect target discovered by Nanlin Guiyi. Nanlin Guiyi quickly dealt with the security monitoring system.

"Okay, Iron Gate, all the system controls have been completed. I have handled the evidence left by your inside line, so you can start to take action!" Nan Lin Guiyi ordered.

Nanlin Guiyi controls all the safety monitoring systems of Putian Machinery Factory. In addition, the safety monitoring systems of Putian Machinery Factory are arranged without blind spots. He wants to see what Mr. Song has the purpose. To be continued.
