Bit Mania [Hacking]

After Xingchu finished speaking, he finally calmed down his emotions, let go of Luo Zixin with a sigh, and turned to leave: "Think about it carefully."

Zixin hugged the LASER and watched the other person go away. His inexplicable emotion made him feel like he was stuffed with cotton. The door of the library was open beside him. He looked inside, and the girl at the front desk was dozing off with her head propped up as usual. , for a moment Zixin seemed to understand something, turned around and walked in with the device in his arms.

With the experience of last time, he is now familiar with the way. He put the equipment in his hand on the ground as quietly as possible, ran to brush the library card, and moved it to the back of the front desk one by one. After all, it is impossible to move alone. Easy, it was half an hour before he hid from the administrator and connected to the Internet.

According to the memory of the previous day, he quickly found the MAC address of the city government's host computer, quickly typed a program, and finally, his finger touched the Enter key.

"Is this an invasion..." Zixin muttered to himself, as if he was asking himself, or Qi Xingchu who had been standing behind him in the past.

Finally, that finger stroked the button and pressed it down firmly.

In an instant, more than a dozen rows of data flashed on the screen, and then stopped. Zixin looked over and his face changed.

Permission modification failed!

He tried to enter a few more commands, and found that they all disappeared without a trace. Obviously, the original weak firewall of the city government has been tampered with... No, it seems that it has not been completely tampered with. What he got from those temptations The responses are all conscious, which shows that the firewall at this time is not unattended, but someone is actively defending themselves on the other side!

Is that you, Qi Xingchu? ——It turns out that you intend to stop me in this way.

Xingchu didn't hide from Luo Zixin the fact that he knew computer technology, he was firm just now, and he walked away without stopping him from going to the library to connect to the Internet. The answer is already obvious what method Qi Xingchu wants to use to stop him.

Zi Xin licked his lips, he had never been clear about the depth of his behavior, and realized the situation he was facing now, leaving aside his sadness and disappointment, on the contrary, it aroused the unknown belligerent factor hidden in the boy's bones.

He took a deep breath and resolutely launched an offensive.The port began to be scanned on a large scale, and Zixin analyzed the feedback data at a glance, looking for loopholes flying by. The intrusion technology seemed to be born deep in the boy's bones, and those numbers and functions were no longer in his eyes. Instead of boring symbols, they are naughty elves with flesh and blood and different personalities. Luo Zixin wanders in the ocean of the Internet and dances with it.

Sitting in front of the computer at home, Qi Xingchu also raced against time to patch the loopholes. He had to integrate the firewall before Zixin, making it an unbreakable line of defense to protect the city government system behind him from damage.

After more than an hour of high-intensity scanning, Zixin finally captured an opportunity from a service tab, which is an application (RPC) component that controls an important process in the system. It patched the loopholes, and Zixin quickly invoked instructions to attack the components with concentrated firepower.

On the other side, Qi Xingchu also discovered the loophole at the same time, and immediately set up defenses. The two confronted each other on this narrow tab. Data packets were intercepted, analyzed, and thrown out one by one. Fortified defenses and those with entrained tampering items must be fully concentrated, otherwise it is only one step away, and the entire line may be defeated——

——This is cyber attack and defense.

Zixin constantly uses the keyboard to input commands. The LASER keyboard is very hard, and it takes a lot of effort to press it. On the one hand, he needs to attack the city government firewall, and on the other hand, he must control the force of his fingers not to be too strong, so as not to let the administrator at the front desk find out. , which soon made his brow drip with sweat.

Time passed by every minute and every second, and the competition between the two was also going on fiercely on the Internet. Suddenly, Qi Xingchu slightly pulled the corners of his mouth, freed his hands from the computer, and leaned back on the seat.

"Game over."

Zixin stared at the screen. The city government's firewall just completed the defense construction of the last module. Now, the defense system added at the beginning of Xingchu has been completely perfected. All the modules are connected in series. Echoing, the scattered sand was finally gathered to form a towering high wall.

Qi Xingchu was the world's top computer security expert in his last life, and his accomplishments were beyond anyone's imagination. Zixin looked at the high wall in front of him. Its structure covered all aspects of the entire system, completely covering it, and the arrangement of program statements was even better. It reveals a kind of sophistication that has been battle-tested, and the use of a few functions lightly is enough to make its defense function to the extreme.

This firewall can be called a work of art.

Zixin scratched the wall outside and marveled, of course he didn’t know how cheating Qi Xingchu’s existence was, and the firewall in front of him had already reached the national level, so he just felt that his level might really need to be improved, so that anyone could be better than him …Because he is proficient, he knows the goods. Now he has long put aside the matter of invading the city government. On the contrary, he is very interested in the firewall. If Qi Xingchu knew that his attention was "successfully" diverted by him in this way , I don't know what to think.

The boy raised his sleeves to wipe his sweat, and was about to continue looking for loopholes, when the library clock struck the time. Zixin looked up and found that he had spent a day in the library unconsciously. Getting up and starting to drive out the people reading in the library, Zixin reluctantly unplugged the power, hugged the LASER, and ran out of the library amidst the crowd at the right time.

After returning home, Zixin carefully recalled the previous offensive and defensive battles. His excellent brain allowed him to clearly remember all the codes he had seen before. How can he break through the seemingly indestructible firewall?He thought about it for a while, and came to the conclusion that his attack was not strong enough. Every attack needed to be executed after writing a certain command, but the gap time was enough to react to his actions at the beginning, and stayed in the library. After a day, in fact, the actual organized attack was very limited.

He also firmly believes that since the computer is man-made, it cannot be perfect. It must have flaws that Zixin can use to break through the defense of this wall. If Xingchu is here, he will definitely vomit blood with anger. I didn't think about giving up at all, I just thought about how to take him down.

Now that the problem is found, it's time to fix it.Zixin made a list on paper, then turned on the LASER, and began to write the programs to be used. In this way, when the time comes to crack the opponent's defense, he only needs to call it directly.

He worked until late at night before he reluctantly went to bed.

The weekend passed quickly amidst the boy's busy schedule. On Monday morning, Zixin came to school with books to start a new week of study life.

Sitting in the Chinese class, someone's head is completely empty, glued to the blackboard without focus, but thinking about various ways to break through the firewall, he pulls out his usual notebook from the desk, and writes down the program , when the time comes, you only need to input them into the computer for debugging, and then you can use them.

Just as he was writing furiously, someone pulled his sleeve suddenly. Zixin raised his head blankly and saw Liu Chang winking at him.

"Luo Zixin, you're not listening to class well, what are you doing!" The Chinese teacher stood beside him, bent his fingers and tapped twice on the desk in front of him.

Shocked, he quickly sat up straight and wanted to put the notebook away, but was snatched away by the Chinese teacher. The booklet was opened in the hands of the middle-aged female teacher. After a few glances, the other party frowned: " What the hell, Luo Zixin, listen to me carefully, you are already a habitual offender!"

"Yes..." The boy nodded tremblingly.

But Chinese and him are naturally repulsive, even the Chinese teacher is no exception, the teacher paused, and ordered: "Look at you, you are listless in class, go stand in the corridor for me, and come back when you wake up! "

Hearing this, the boy stood up silently under the pity eyes of his classmates, and walked out of the classroom.

Because of the serious partiality of subjects, Zixin's grades are really not good, and the class he is studying in is also a poor class, which is located at the end of the entire corridor. After he walked out of the classroom, he leaned his back to the window installed at the end of the corridor. , the already thin figure looked extremely pitiful.

He stayed in place for a while, and his mind was immersed in the world of programming. How can he break through Qi Xingchu's defense?He needs a means...

Zixin looked out of the window in trouble. The slightly chilly spring breeze blew in from the wide open window, making the boy squint his eyes comfortably. Suddenly, a big gray pigeon flew in from the window, landed on the window frame in front of Luo Zixin, tilted its head to look at the boy, and solemnly lowered its head to pick up the leftover bread crumbs that some student had eaten between classes. , even without fear of strangers.

He looked at the visitor from the sky. For a pigeon, he was really fat.
