A few days after Mao Mao took away Hanlon's laptop and network communication equipment, the two of them met in a secluded small park.
Maomao looked at Hanlong excitedly and said: "Brother Long! I have given our computers and network equipment the special communication security card for the city's local area network, and at the same time applied for a random floating IP account for the computer. This IP account can be attached and used Any legal ready-made IP account can access the Internet! Randomly floating IP accounts can avoid any inspection by network surveillance! Therefore, starting from today, we will crack the flight center LAN, and at the same time crack the communication protocol between the city LAN and the satellite network, as well as crack the satellite network Communication protocols with the international Internet, etc.! In this way, we can do the next step!”
Hanlon said excitedly: "How long will these jobs take?"
"If it goes well, it can be completed in one and a half months! If it doesn't go well, don't say anything!"
"Oh! Then let's hurry up and start working! Where will the work site be located?"
"Brother Long! Let's set it up in your dormitory! You are a biophysicist, and most people think you don't understand network technology! Even if something happens, people will not doubt you!"
Hanlong wiped the sweat from his forehead and said, "Okay! You can take the equipment to work in my room tonight!"
After that, Hanlong and Mao Mao spent their evenings and rest days in Hanlong's dormitory to decipher the communication protocols and secret messages of each gateway.
When working, they constantly change computers and network communication equipment to retrieve nearby legal IP addresses to access the Internet, so it is difficult for network supervisors to monitor their behavior on the Internet.
Half a month later, Maomao and Hanlong cracked the LAN of the Science City Flight Control Center. They could freely access any database of the LAN, as well as the office command control and delivery system.
At this time, Mao Mao began to pre-create his and Hanlong's pilot electronic files according to the file format and management method of the local area network. The electronic file used personal identity authentication data such as Mao Mao's or Hanlong's electronic photos, electronic fingerprints, and electronic blood types. .
At the same time, 4 hours before the operation, they must use these two prepared electronic files to replace the two real flight control center registered pilot files!
After that, they began to decipher the communication protocols and secret files between the city's local area network, satellite network, satellite network and the international Internet.
Since the communication protocols and secret files of these gateways adopted new software and hardware encryption technologies, after a month, Mao Mao tried his best to still be unable to crack them.
One night, Hanlon and Kitty sat on the grass in the park near their dormitory building and talked.
Hanlong looked at the kitten in confusion and said: "Kitten! Why are these gateways so difficult to crack?"
Mao Mao smiled bitterly and said: "The communication protocols and secret files of these gateways are in a floating state, so we cannot crack them with fixed algorithm programs! Unless we get the operating algorithm program that controls this floating state! Otherwise, close to our laptops It is impossible to crack these gateways! Even if you crack these gateways on a super mainframe computer, it will not be possible to crack them within a few years!"
Hanlong said desperately: "Oh! So we can only wait to die in this science city!"
Mao Mao said with a smile: "Brother Long! Maybe we are not so pessimistic! The technical director of our network maintenance and repair center is a Chinese. He is over 40 years old. He used to work at the science city's external network maintenance and repair center. Because he offended the The white officer of the institute, so he was assigned to work in our institute! This person must have the program to control the floating state of the gateway! If we find this person to cooperate, all our problems will be solved!"
Hanlong said excitedly: "Okay! Kitten! You take advantage of your work opportunity to get in touch with this person and understand his character and thoughts in advance! If it's appropriate, we'll talk to him together!"
Kitty nodded and said: "Okay! When I go to work tomorrow, I will go to his office to ask him a few questions!"
...
One night a few days later, in a small park near the 116 Building, Hanlon and the kitten sat on the grass and talked.
Mao Mao looked at Han Long and said: "Brother Long! I have contacted that person! I feel that this person is unpredictable and I can't grasp his character and thoughts! Why don't I ask him out and you come and talk to him? !”
Hanlong smiled and said, "Okay! When you go to work tomorrow during the day, you can find an excuse for network failure and ask that person to come to my office and I will talk to him!"
"Okay! I'll take him to the Supervision Office of the Institute of Biology to find you tomorrow!" Mao Mao looked at Hanlong innocently.
Shortly after starting work the next morning, Mao Mao brought a middle-aged Chinese man to Hanlong's office at the Institute of Biology.
Although the middle-aged Chinese man is in his 40s, he looks only in his 30s. He is of medium build, very thin, energetic, with fair skin and black hair, a typical Chinese appearance.
The three of them were having a coffee conversation on the couch.
The middle-aged Chinese stared at Han Long expressionlessly and said, "I heard your name is Aaron! I am also Chinese, my name is Liu Shan, and most Chinese call me Brother Shan! You can call me whatever you want!"
Han Long smiled and said: "Brother Shan! It's such an honor to meet you! I have a few questions to ask you!"
Liu Shan smiled and said, "Okay! Just say it!"
"Brother Shan! The supervisor of my biological institute and the staff of the institute's research office reported to me that they often lose some network data, making it difficult to carry out their research work! How should these problems be solved!"
"Alas! There are more and more biological scientists who have mastered network technology. Therefore, when they encounter competition, they will attack each other through the Internet, put computer viruses on competitors to plagiarize them, and delete their opponents' data. It is common! As long as competition still exists, This kind of thing is unavoidable! Let them take precautions on their own! The preventive measures are: first, to reduce working in the network environment as much as possible; second, when working in the network environment, save the data that needs to be saved in a timely manner To a mobile storage that is isolated from the network. This may be the best way to do it!"
"Thank you, Brother Shan! Brother Shan! Where do you think these cyber hackers come from? Our director, Dr. Krader, said that these hackers may come from the international Internet in the outside world."
Liu Shan said nervously: "Impossible! There are two gateways and secret files between the city's local area network and the international Internet in the outside world, the external network. It is impossible for hacker technology based on personal computers to break through these two gateways! Unless someone gets it Dynamic runner for these gateways!”
Hanlong stared at Liu Shan with a serious face and said, "Brother Shan! Who do you think is most likely to obtain these procedures?"
Liu Shan wiped the sweat from his forehead. He looked at Hanlong with a pleading look and said, "It's hard to say, but it must be those who have been exposed to this program! Aaron! If you have any conclusive findings, you can follow me directly. explain!"
Hanlong nodded understandingly and said, "Okay! Tonight you go to the small park near the 116 Building, and we will talk there!"
After Liu Shan breathed a sigh of relief, he smiled and said, "Thank you! I live in the 117 Building. I'll wait for you there after dinner!"
After the conversation, Liu Shan and Mao Mao left.
In the evening, in a small park near the 116 Building, Hanlong, Mao Mao and Liu Shan sat on the grass and talked.
Liu Shan stared at Han Long and said, "Aaron! What did Clad tell you?"
Hanlong smiled and said: "Brother Shan! He said you know how to connect the internal network with the external network!"
Liu Shan said angrily: "This bastard! You must know that Krad often sells your institute's scientific research results to private companies in the outside world through the Internet and profits from it. Last time he asked me for that program , but, he hasn’t paid me until now! Maybe he lost that program now, so he asked you to ask for it from me! You tell Clad, he won’t pay me double the price this time! He can’t even think of starting from I got that program here!"
It was the first time that Hanlong knew about the deal between Clad and Liu Shan. Hanlong suppressed his excitement and pretended to be calm and said: "Brother Shan! I don't care about the matter between you and Clad! This time I think about it myself. If so, please tell me the price! I can pay you in cash!"
Liu Shan said in shock: "Oh my god! Why do you want this?"
Hanlong smiled and said: "Kitten and I want to leave here and return to the free world!"
Liu Shan excitedly wiped the sweat from his forehead and said: "I feel you have the ability, you can do it! But you must take me with you! If you don't take me with you, I won't give you that thing, and I still have to go The headquarters will report you!"
Hanlong smiled and said: "Okay! Let's take you with us! After returning to the free world, I will definitely pay you a huge sum of money! How much do you think I should give you?"
Liu Shan smiled excitedly and said, "Deal! I've been here for more than 20 years, and I've really had enough! Returning to the free world is my lifelong dream! After I return there, you can solve my living problems such as food, housing, etc. , and then you just need to give me a little more pocket money! My requirements are not high!"
The three of them looked at each other, smiling happily!
