Zhao Jun said coldly: "It seems that some people are very interested in the secrets of the Red Flag Factory." ”

Li Yongfang said: "Then what do these people want to know about the Red Flag Factory?"

As soon as he finished saying this, he immediately realized something, and blurted out almost at the same time as Guan Jiyu: "Huashan!"

Huashan is Huashan engine, it is a new high-thrust aero engine independently developed by Huaxia, according to international standards should be classified as the fourth generation of engines, becoming the third country that can independently develop the fourth generation of aero engines after the United States and Rakshasa countries, Huashan is its external codename.

After more than 10 years of hard work, the engine has basically completed the production and finalization, and will be delivered to the troops to lead the flight, and the engine is equipped with the fourth-generation fighter of the Air Force that the outside world is concerned about, and it is said that the performance indicators of this aircraft are comparable to the fourth-generation aircraft of the United States, and some aspects even surpass. Now the test bench in the factory is carrying out the production of Huashan engine finalization long test work, these data is the final data of the engine in the future, if these data are known to some interested people, then the flight performance index of the aircraft can basically be calculated......

"Immediately and thoroughly inspect the entire network!" Zhao Jun said in a deep voice.

Hongqi Factory is a large state-owned military factory, the factory covers a very large area, and the network is also all over the factory.

Guan Jiyu looked at the topographic map of the Hongqi factory, and secretly wondered in his heart: The guy who carried out the cyber attack would definitely not be stupid enough to stay in the factory and wait for someone to arrest him, so how did he complete the intranet attack?

He further deduced that if someone somehow connected to the intranet in the factory, and through a small hair extension device set up nearby, it was completely possible to carry out a remote network attack in the outside world through wireless means.

According to his inference, the operation team used a small reconnaissance device to check the suspicious wireless signals one by one in the factory area, so that the scope of the search could be greatly narrowed.

Eventually, as expected, they spotted a suspicious signal near the test bench where the long test was taking place.

When they came to a plumbing room, they found that the door here was not locked, Guan Jiyu pushed the door open with a push, and several people walked in.

Guan Jiyu took a closer look inside and saw a network junction box in the corner, this box had a metal shell, but the outside was locked.

He took a closer look at the lock cylinder with a flashlight, the corners of his mouth couldn't help but sneer, raised the camera and patted it, and then said to Li Yongfang, who accompanied them: "This lock hole has traces of being pryed, is there a key?"

The technician who followed hurriedly handed the key to Guan Jiyu, Guan Jiyu opened the junction box, and saw that there was a device inside, the indicator light on it flashed green light brightly and darkly, and two black cables stretched out from this equipment, and the four silver pins at the other end of the cable were inserted directly into the network cable shell.

Zhao Jun frowned and asked, "What is this for?"

"This house is a plumbing room, and sometimes there are sundries or something, and the door is not locked. Li Yongfang looked at everything in front of him, and was really surprised, although he was a layman on the Internet, but what he saw in front of him, he also understood that it was through this that the enemy connected to the network and stole data.

Back in the conference room, Guan Jiyu held a piece of network cable in his hand and a wire clip in the other hand, and glanced at everyone: "I will first insert this clip into the network cable, and then connect it to this small signal controller, which is the device we just saw, so that I can connect with the entire network." ”

Seeing Li Yongfang and the others, they all had shocked expressions. Guan Jiyu added: "You see, this kind of installation method is very professional, and ordinary people can't do it. ”

Li Yongfang looked at the thing in Guan Jiyu's hand in surprise: "Comrade Xiao Su, can this really be the controller?"

Guan Jiyu replied affirmatively: "It should be." I'll take it back and make sure again, and I'll check the whole factory thoroughly to see if there's anything else in it. ”

Li Yongfang bowed his head and was silent, his face was full of frustration, and he sighed heavily: "The enemy's hands have reached our home. ”

Guan Jiyu changed his relaxed and naughty appearance in the past, turned around and said to Zhao Jun seriously: "I'll take this thing back and check it first, and report the results to you as soon as I get back." ”

The next day, the conference room of the confidentiality department of the Hongqi factory.

"This is a high-frequency controller, and it's the highest-end model at the moment, and there's a tiny memory inside, and as long as the server is plugged in, it's automatically activated, and the people behind it can use it outside to enter the network, steal the data on the network, and then send the data out through the controller. Guan Jiyu raised the transmitter in his hand.

"Then what is its launch range. ”

"150 meters. ”

"150 meters? Isn't that in our factory?"

"If we look at the map, this is the test bench, and with this point as the center, it is possible to receive information within a radius of 150 meters. ”

The projection in front of them clearly shows an electronic map, in which a circle is drawn around the test bench, which is a circle with a radius of 150 meters, and in this area, there are some parts of the factory, and some areas outside the factory are also covered.

"Now there is another question, in this area, I don't know if the other party is using a relay or a receiver?" Guan Jiyu said.

"Does it make a difference?"

"Generally, a transmitter with little power like this will need a relay equipment as a springboard, and after receiving the information, it will be transmitted to a farther place, and it is not excluded that someone may receive information in this range. ”

"The goal of the other party is to receive the message, and our goal is to find the person who receives that goal. Zhao Jun stared at the electronic map and whispered.

Li Yongfang led Zhao Jun and a few people to the duty room of the test bench factory, and said to the attendant: "These people are sent from above to inspect the safety and security work, is there any situation recently?"

The attendant was about to change shifts, and he blurted out, "No, everything is normal." ”

Li Yongfang picked up the register, flipped through the pages one by one, and suddenly his eyes stopped on a record - it was the registration when Li Shan led Li Lianghao into that day.

He pointed to the registration record and looked at the attendant: "What's the matter with these two people?"

The attendant was taking off his uniform, and his head hurriedly came out of the neckline: "Oh, this is brought by Li Shan, saying that it is a new employee from their unit, who came to study and learn." ”

Li Yongfang didn't say anything more, the person who came to take over had already entered the house, and the attendant picked up his bag and greeted Li Yongfang in front of the windowsill: "Secretary Li, then I'll go first?"

Li Yongfang nodded: "Go home and have a good rest." ”

The three of them then called up the surveillance and locked on a stranger who had come in with Li Shan.

The stranger was wearing a hat on his head, seemingly intentionally or unintentionally, but he could always effectively avoid the camera shooting angle, so the cameras everywhere did not capture his face, and it could be seen that this guy was obviously very experienced, so he could only judge the characteristics of this person by using Li Shan next to him as a reference, and his height was about 1.75 meters, his body was well-proportioned, and his age should be less than 30 years old.......

Back in the office, the three of them suddenly fell silent. Li Yongfang's face was very ugly, and he couldn't help but look at Zhao Jun who was contemplating on the side. Zhao Jun didn't speak.

Now that all the doubts are focused on himself, no matter what, he can't escape it, Li Yongfang sighed and said with some difficulty: "I...... Through inspection, we found out that Xiaoshan brought a stranger to the test bench the afternoon before yesterday......"

Zhao Jun and Guan Jiyu glanced at each other, feeling a little embarrassed, and didn't know what to say. But Li Yongfang himself continued: "In short, now Xiaoshan is suspicious, this is a fact. Rest assured, I'm ...... I will never shield my child, and if he really has a problem, I will avoid it according to the rules, and I still have this awareness. ”

Guan Jiyu looked down at the ground and didn't squeak. Zhao Jun really couldn't bear to look at Li Yongfang's sad and sad appearance, and hurriedly comforted: "Secretary Li, I dare to guarantee one thing, although Xiaoshan is a little playful, he is still very upright. And I think it is even possible to rule out the possibility that Koyama will take the initiative to help the enemy. ”

Li Yongfang was stunned suddenly, and his expression was mixed with joy: "Really?" But I was thinking in my heart that you have never been in contact with Xiaoshan, how can you be so sure?

Guan Jiyu, who had not spoken for a long time, asked in a low voice: "Zhao, do you have any evidence?"

Zhao Jun smiled slightly: "There is one thing I have never told you, I met Xiaoshan as early as last year. ”

As soon as this remark came out, the words shocked everyone.

Looking at the puzzled eyes cast by others, Zhao Jun continued: "Last year, Xiaoshan went on a business trip to the 727 base, and encountered some special circumstances, some details that I am inconvenient to disclose, but what I want to tell you is that in this incident, Li Shan showed very courage and tenacity, he has the courage and perseverance that we ordinary people cannot have, and his values are absolutely positive, so I firmly believe that even if Xiaoshan makes a mistake, it is never his initiative." ”

Li Yongfang was relieved and grateful, and the corners of his eyes were a little red: "I'm not saying that this kid has a problem in nature, if you want to say that he will take the initiative to join the enemy, betray the interests of the country, and kill me, I don't believe it." But his sense of secrecy is too poor and he doesn't have the slightest vigilance, so he is likely to be taken advantage of. After saying this, I was still a little indignant.

Zhao Jun stared at Li Yongfang and said to Li Yongfang word by word: "Secretary Li, we understand your feelings. We have 100% trust in you, but whether there is a problem with Xiaoshan or not is ultimately up to the facts. ”
