Chapter 35: Let me guard you

Rovin's computer configuration is very general, it seems that he usually does not use it, even the most common daily maintenance has not been done. He can help him repair the system vulnerability first, and then download several applicable tools, such as multi-language programming software. If he can, he would like to change the system. Unfortunately, this is not his computer. He can only wait for a chance to assemble another computer.
"Cocoa, what are you doing?" Feng Yi took his head and curiously looked at the fingers that were still flying on the keyboard.
Still able to move a meal, turned to look at the seal, and asked: "Want to learn?"
The seal nodded hard. He thinks it can be very powerful. It seems that everything is understood. It used to be e-language and now it is a computer. On the other hand, I don’t know anything about it. He doesn’t like the feeling that he is left behind.
"Okay." You can still let yourself sit down and teach him to play the computer from the simplest operation.
In this era, the computer penetration rate of the country is less than 50%, far lower than that of Europe and the United States, and technology is only at the initial stage. Of course, here is the ordinary people, the hidden masters are not without.
The ability to learn aloud is really strong, but it can be just a simple demonstration, he can quickly master, and give the opposite.
In the morning, I passed happily in the process of teaching and learning.
Lunch was sent by the police officer responsible for protecting them. After the police officer left, he still had one more mobile phone.
The seal looked at him with amazement: "You actually stole..."

Hey!
can still signal him not to make a sound, then take the phone card out of the phone, and check if the phone has any Trojans or other monitoring software installed, and finally hide it in a vase. The mobile phone card was thrown into the toilet and washed away.
"Coco, what do you want?" asked Feng.
"I need a mobile phone to do something, I hope that the police officer will not mind." Can still show a sorry expression outside the door. If you have money later, then compensate the police officer.
Luo Wen has stuffed some money for him, but the money can't afford a mobile phone. He doesn't want Luo Wen to know that he has a mobile phone, so he can only make a decision. With a mobile phone, you can buy a mobile phone card with your money.
Looking at him silently, stealing the mobile phone is no problem, stealing a police officer's mobile phone!
"Hey, you will help me to cover up." Although they are currently in protection, their personal freedom has not been greatly restricted. As long as they are accompanied by police officers, they can still be active nearby.
Shang Ke and Feng Wei walked into a small shopping mall under the leadership of the police officer. The seal received a good indication and helped him to divert the attention of the police officer.
It is still possible to buy a mobile phone card quickly, and then run back before the police officer finds it, only two or three minutes before and after.
Several people strolled for a while, bought some snacks and books, and went back.
After returning home, you can take the phone out of the vase, install the phone card, then drill into the study, open the computer and start writing the program. He wrote a virus Trojan called "jumping worm", which is not only highly concealed, but also cross-infected.
When he was in the space, he relied on his memory to remember all the source code, so it is very easy to write now.
Still can look at the attention, did not pay attention to the seal has been standing next to the quiet look, a string of code program flashed quickly in his pupil, as if unfolding a wonderful world.
Three or four hours, I was finally able to write the jump worm, but he did not stop, and began to write anti-monitoring firewall.
However, less than one-tenth of the time was completed, and Rowan rushed back.
I was able to hide all the things on my computer. I looked up and saw Luo Wen’s serious expression. I couldn’t help but ask:
Detective Luo Wen, what happened to you?

Luo Wen sighed and replied: "Jessen's cell phone has been unable to get through, I thought you had an accident."
Jason was the police officer responsible for protecting them, and the one who had stolen his mobile phone.
I can't change my face and say: "The mobile phone can't get through, you can also hit the landline at home."
Rowan was silent for a moment and returned two words: "Forgot."
It is still speechless first, and then some moved. If you don't worry about them, you won't be so anxious.
"Tomorrow I will send you to the Children's Puzzle Activity Center." Rowan said, "The regulatory system and protection measures there are very good, you can be there during the day."
There is no opinion about the nature of the seal.
In the evening, he went into the study and spent five or six hours writing the anti-monitoring firewall. During the period, Rowan had seen it a few times. When I saw two children playing games, I uttered a sentence saying, "Don't play too long."
It is still possible to put a firewall and a jumping worm into your mobile phone, and try to run without problems, which shows a satisfactory smile.
The next day, Rowan drove two children to the puzzle activity center. In the car, he could quietly take out his mobile phone and open the jump hopper. He only saw the words "being jumping" on the screen, ten seconds later. , "Jumping success."
It was still possible to successfully send the jumping worm virus to Rowan’s mobile phone. From now on, he can monitor every phone call, every message, every email. The most powerful thing is that he can use Rowan's mobile phone as a springboard to infect all mobile phones and computers within 15 meters of him. The premise is that Bluetooth or network is turned on, and there is no particularly powerful anti-monitoring program.
Luo Wen led Shang Ke and Feng Yu into the activity center, and a female teacher immediately came over to receive. Luo Wen had already greeted the person in charge before, so the teacher did not have a particularly unexpected expression when he saw the two children.
Shang Ke and Feng Yu were taken to a small class with more than a dozen children playing, the youngest is about six years old, and the biggest one is only ten years old.
Rowan was very satisfied with the environment here. After a round, he left, leaving only one policeman to stay outside.
The teacher who took care of them was called "Juli". She introduced them to other children first, then took them to a cartoon table and chairs and brought them a lot of toys.
It can be swept a bit, mainly Rubik's Cube, Jiuhuan, Jigsaw, Hanno Tower, building blocks, graphic cards and drawing tools, etc., all of which are educational toys.
Teacher Julie probably wants to look at their preferences and then conduct targeted training and training.
Still can't be interested in the entertainment of children, it is quite curious.
He took it up and looked at it, but he didn't care about the nine links. Finally pointed to Hanno Tower, asked Shangke: "Cocoa, how to play this?"
The Tower of Hanoi is the kind of toy used to test the intelligence of the orangutan in the rise of the orb. It consists of three wooden poles labeled a, b, and c. The pole has a number of perforated discs. The size of the disc is from bottom to top. It becomes smaller in turn. Follow the rules, move the disc back and forth, and finally move to the same pole to see how many times you need to move.
Those who have studied computers should have done exercises similar to the Tower of Hanoi, and the recursive algorithm of Tower of Hanoi is one of the preliminary algorithms of the C language.
Can still take over the Tower of Hanno, pick up the disc and start moving. Within one minute, they successfully moved six times in different orders.
The seal was inconceivable, and the teacher next to Julie also showed the color of surprise.
Hanno Tower can still be handed over to the seal. The seal was first completed by recalling the acceptable steps, and then began to try different ways of moving. However, in ten minutes, he was even tempted by some rules.
Suddenly, I feel that this guy is a computer talent. The Tower of Hanoi algorithm is not difficult, but the process of deduction is very painful. It is impossible to complete without clear logic.
Teacher Zhu Li watched them play with Hanno Tower, and they were excited: these two are not ordinary children!
After the teacher Zhu Li left, she could still pick up the nine-ring and asked: "I don't like this?"
I glanced at it and said: "I used to get tired of it."
Acceptable: "..." Is this guy actually a genius?
Squatting on the toilet, you can still sit on the toilet, turn on the phone, and plug in the headphones. Rowan's call record is immediately displayed on the screen. He ignores this and activates the jumper, letting it search the network on the side of Rowan, and then walk around the network.
One life two, two three, three life.
The ultimate goal is still the server and electronic monitoring inside the police station.
Although the theory of jumping worms can be spread indefinitely, it is limited to the backwardness of the mobile phone system. The monitoring can only be one-to-one and cannot be carried out at the same time. And the jumping worms that are spread out can't be removed unless he can black into these computers one by one.
You can still not worry that the jumping worm will be discovered, and you don't have to worry about it for at least four years. It is attached to other programs and can be disguised by itself. As long as the main program is not activated, it is basically invisible and takes up very little space.
With today's technology, unless it is targeted killing, it can't be found.
If he has his own computer, it is much simpler to spread the jumping hopper, but unfortunately it can only be step by step.
In the next few days, Rowan became a mobile source of publicity, but wherever he passed, people who had contacted would leave the mark of jumping worms.
Hard work pays off, but in an accidental opportunity, through the surveillance video to capture the image of a member of the gang, and then along this clue, he found a den.
"I think there may be secrets hidden in the two children," Angeli said to Rowan. "Otherwise, the group doesn't have to bite two children and actually find the center of the puzzle activity. Although not yet. Determine the identity of the other person, but apart from the two children, what else is worth paying attention to?"
"I feel the same." Another police officer, Bent, agreed. "Rowen, you have the most contact with the two children. Any thoughts?"
Rowan shook his head and said: "For the time being, I will continue to communicate with them to see if I can get any clues. Now, let's go back to the case first..."
At this moment, a technician suddenly reported: "You are coming over and I have received a strange email."
Several people rushed over and there was an audio file and an address in the mail.
Click on the audio, which plays a man's call, which seems to be checking the delivery location.
Rowan looked at him and asked, "Can you find the source of the mail?"
The technician was helpless: "No way."
"Go." Rowan wrote down the address in the mail and led the team members to attack quickly.
Whether it is true or not, they have to verify it.
Fortunately, the intelligence is real, they took a criminal den.
However, they did not associate this small gang with the towers they had been tracing at the moment, that is, the stalking can still be associated with the group of people who were sealed.
In the following two months, the police station received three similar pieces of information, but never found the source.
The tower was repeatedly attacked, and the internal situation was tense and began to contract.
The crisis of the can and the seal was temporarily lifted, and Rowan and others thoroughly worked with the group. No one knows, all this turned out to be a "child" to help behind the scenes.
A year later, the contract was sent to the foster home for a monthly subsidy of 500$. Although Rowan is very reluctant, he also knows that he is not qualified to adopt them in his family career.
This year, Shang Ke and Feng Yu officially became a primary school student at Fran Elementary School, and they have their own e-names - "Bunuu" and "Ian ian".
