Zhang Chao nodded: "I understand."
"Okay, here comes the meat show." Xu Haocun continued, "This firewall installed on the base station is actually a piece of hardware, so it cannot be broken through the external network. This Xinlian Building 100% has its own base station. And there must be a firewall installed, so if you want to hack into their network, you have to climb to the base station above and manually replace the firewall without attracting their attention."
Zhang Chao asked: "Where is their base station?"
"Of course it's on the balcony on the top floor. It's a huge antenna-like object with many alloy tubes. It's easy to spot."
Zhang Chao said: "Okay, leave this problem to me, but I don't know what a firewall looks like."
Xu Haocun took out a cylindrical object from the box. It looked like an ancient lamp starter. "This is it. Zhang Ying has already prepared it for you. You just need to take it with you and replace the original firewall." That’s it.”
Xu Haocun handed the firewall to Zhang Chao and continued to remind: "You see there are two pins under it. It is plugged in and out directly. When you replace the firewall, the speed cannot exceed one second, otherwise someone downstairs will The machine will alarm and alert the network administrator downstairs. At that time, he only needs to take out his mobile phone and take a look, and he will find that the key on the firewall has changed, and your whereabouts will be exposed. See the string above Characters are missing, this is the initial firewall key."
Zhang Chao couldn't help but frown: "Can't it exceed one second?"
"Well, so if you feel unsure, it's best to practice it first. Just find a piece of cardboard, poke two holes in it and you can practice."
"With the firewall turned off, how long does it take you to figure out what's going on in the entire building?"
Xu Haocun shook his head and said: "Turn off the firewall is just one step. There is another step, which may be more dangerous. I don't know if you can do it."
"What steps?"
"In order to improve the information security level of this kind of building, they deliberately blocked external signals at the beginning of construction. People inside the building, whether it is a phone or the Internet, cannot transmit it to the outside, and of course the people inside cannot receive it. signal. But they also have the need for external communication, so they will install a data sending and receiving device on each floor, and this thing, we usually call it a communication box, is actually the second firewall."
Zhang Chao frowned again, "You mean there are them on every floor?"
"Yes, there is one on every floor, but you don't have to worry, it is not inside the room, but outside the floor. Oh, the first floor is inside the room, but the first floor is usually the lobby, so don't pay attention to it, just go directly Just start on level 2. They will have a signal light indicating the location, and if it is in normal use, it will flash green."
"What should I do?"
Xu Haocun picked up another thing: "This thing looks familiar, it is a network cable connector. Although network cables have been eliminated, they have been reborn elsewhere. Although this thing looks like a network cable connector on the surface, it is There is a very powerful overclocking signal sending device built into it. All you need to do is find each communication box, disassemble it, unplug the network cable inside it, plug this in, and then plug the network cable into the network connector. After doing this, the second protective wall will be completed."
"Is there a third firewall?"
"Haha, no more, just these two. As long as you get them done, I will be able to retrieve all the monitoring data of the entire building very quickly. It will not take more than 3 seconds."
Xu Haocun has watched many spy blockbusters. As early as the end of the 20th century AD, there were many such blockbusters being screened in public. In the movie, those awesome agents used different methods to climb to the top of the floor to complete missions that were impossible to complete one after another. Xu Haocun was curious about how Zhang Chao would do it.
Xu Haocun soon saw it, and he found that Zhang Chao had done enough preparations. When Xu Haocun finished describing the mission objectives, Zhang Chao immediately called another person over, who took out two pieces of equipment: one was a silver box like a backpack, with two straps on it; the other was a piece of clothing.
"What are these things?" Xu Haocun asked curiously.
"These are the gadgets of our scientific research team." The man explained with a smile, "This backpack is an anti-gravity device. After you put it on your back, you can perform light kung fu as described in martial arts novels. With a little training, you can perform light kung fu. It’s so easy to jump from one building to another.”
"This piece of clothing is called a gecko suit. It actually has a certain anti-gravity function, but anti-gravity is not its main ability. After wearing it, you can easily climb walls like a gecko, not to mention glass walls. It can also block ordinary bullets."
Xu Haocun sincerely praised: "It's great. With it, it will be more convenient to clean the glass."
"Haha, Spider-Man can't afford this kind of equipment. They are not circulating on the market. So far, only the military is using them among various countries."
"Oh, you are from the scientific research team? May I ask my eldest brother Gao's name?"
"My name is Dai Zhicong. Welcome to join us, brother Xu Haocun."
"Ahem, I was tricked into this by the group leader." Xu Haocun smiled bitterly.
"Haha, that's his usual style. In fact, it's not bad here. If you stay for a long time, you will find that although our salary is not high, the leader never restricts us from spending money. As long as you have a legitimate reason, how much He can apply for all the funds for you, which is something you can’t do in other civilian units.”
The group of them quickly arrived near the Xinlian Building, but they did not get close to the Xinlian Building. Instead, they crossed a street and drove into the building next door to the Xinlian Building, the underground parking lot of the State-owned Assets Group.
A soldier greeted Zhang Chao in the parking lot and reported some situations to him in a low voice. Zhang Chao just nodded and said nothing.
Then they went upstairs in batches and arrived at the 19th floor. There were many people upstairs, apparently monitoring the situation in the building opposite.
Zhang Chao summoned people to the conference room. Dai Zhicong from the scientific research team and Xu Haocun from the technical team were present at the same time, but they were asked to put all communication equipment outside the room.
"Advisor Tong, tell me your plan of action."
"Yes, battalion commander."
Staff Officer Tong cleared his throat and began to speak: "Our first task in this battle is to rescue the hostages, and the second is to eliminate the enemy. We will focus on raids, supplemented by strong attacks, and try not to alert the enemy before they are discovered. According to the plan, the surrounding people can only be evacuated after dark."
"From 6:00 pm to 8:00 pm, these two hours are our time to evacuate people. We will evacuate all residents in all buildings within a 300-meter radius around the Xinlian Building. This task will be handed over to the First Company and the Third Company. Completed, the second company is responsible for supervision and security."
"From 8:00 to 8:30, the three companies must quickly complete the combat deployment and surround the entire Xinlian Building for me."
"Starting at 8:30, the special operations team sets out to assist the technical team to destroy the other party's network firewall. It is required to complete it within 20 minutes. The company must pay attention. During this time, you must find a way to attract the attention of passers-by downstairs. Don't let anyone They have their sights set on the Credit Union Building.”
"At 8:50, the technical team started taking action. Comrade Xu Haocun, how long will it take for you to take over the other party's network?"
Xu Haocun said hurriedly: "As long as the previous work is done well, I can definitely get it done in one minute." When he was in the car, he said that it could be done in three seconds, but now he felt the words coming to his lips. I can't talk too much, so I temporarily changed it to one minute.
Staff Officer Tong said: "I'll give you 10 minutes. If possible, I hope you will also intercept the other party's communication equipment. If the other party is talking to someone outside, I want to know what they said."
"Ah - please wait a moment." Xu Haocun hurriedly went out and brought in the box prepared by Zhang Ying, "Well, team leader Zhang Ying prepared a box of miniature monitoring equipment. It is magnetically adsorbed. You are installing network cables to connect it. When using the device, you only need to attach it to the communication box, so that no matter who is calling inside, you can monitor it. But this thing consumes a lot of power. I just read the manual in the car and it is effective. The working time is only two hours.”
"Okay, thank you, please take a seat." Staff Tong continued: "After the technical team's work is completed, at 9 o'clock in the evening, the roads will be blocked and the streets will be cleared. The local police will cooperate with our actions. The attack will be launched on time at 21:15 ."
"In this operation, the first company is responsible for attacking from the ground, while the second company responds to emergencies and is ready for rescue at any time. The sniper upstairs must always monitor the opposite window. If the enemy is found launching missiles from the window, he must immediately carry out the operation. We cannot allow them to successfully launch if they are blocked by snipers. This is an urban area and the damage that missiles can cause is too great. We cannot cause this city to suffer such huge losses because of our actions. The third company is responsible for the aftermath and must intercept all enemy vehicles and Flying tools cannot allow them to escape.”
Zhang Chao spoke promptly: "The Second Company still has a task, which is to protect the two comrades of the scientific research team and the technical team. They have no combat effectiveness. You must not let them suffer any damage. Second Company Commander, do you think you should let the Third Squad Leader How about Li Youcai leading the team to stay and protect the two of them?"
He did not give an order, but asked the second company commander for his opinion in a consultative tone. It was considered a personal suggestion. If the second company commander was really stubborn and refused to agree, he would not insist on it, as long as the second company could complete the task of protecting the target. That's it.
A handsome young man wearing glasses stood up and said: "Report to the battalion commander, I have no objection."
The secret base of the Gray Wolves.
Meng Qingxiao was still depressed because he was not allowed to join, and ran to the crazy sandbags on the rooftop. At this time, Xu Haocun from another world ran over to him and said to him furtively: "Follow me."
"what?"
"You'll know when you get here."
The two came to Zhang Ying's office. Zhang Ying and Meng Yuxin were both here, staring at the computer screen, not knowing what they were looking at.
Meng Qingxiao came up, his eyes widened suddenly, and he exclaimed: "Damn it, how did you do it?"
