"The complicated life and death in the world are ...... by the sky", listening to the noisy music outside, Yang Feng walked in confusion with his hands in his trouser pockets. I always feel that there is a burst of gloom over my head, I don't know how long I walked, I looked up into the distance, and there was a familiar street, as if the city only turned a corner, all the streets, all the buildings were the same: a gray-black 8-story small building topped by a circular dome - this is the unified architectural style of the city of Haierbin. The streets at dusk are full of frowning pedestrians who don't know where to go, and occasionally someone will snug a real estate advertisement into your hand and turn to the next pedestrian with a smile.

I don't know when it started, Yang Feng seemed to feel that there were people around him all the time, and no matter where he went, a black sedan would appear around him. This inexplicable sense of fear made him feel suffocated, and he even grabbed the railing on the side of the road, trying to lower his head and lean there to breathe. "At this time, someone is following me, and the sixth master has just ...... Forget it, don't think too much", but when he just took a few steps, he opened his eyes and looked straight ahead: "No merit, is this 30,000 yuan ......."

Although Yang Feng is not familiar with the world, as a high school student with superior intelligence, he naturally has a strong sense of distress. He kept thinking about everything he had done with the sixth master in his mind, and a terrifying reasoning slowly emerged: "The Internet café management software I made at the beginning was not used at all in the actual Internet café scene. "......" means that this software is actually a "......" ARP spoofing technology for other people to use, which can disconnect the network connection imperceptibly without installing the client, combined with network card power on/off, weak password and port scanning, you can arbitrarily shut down any machine in the same LAN.

"Oh my God!", Yang Feng's eyes flashed with fear, and he clenched his fists: "The sixth master is using this software to achieve intra-LAN attacks, although I don't know how to sneak into other LANs, but at this stage, the sixth master must have heard something...... The 30,000 yuan is clearly hush money! There should have been something discovered by the police. ”

Thinking of this, Yang Feng leaned in front of the stone lion at the door of the bank, his body trembled involuntarily, and he felt that he had suddenly lost his strength, and sat on the cold marble steps with a "plop", covering his face with his hands, as if he was unwilling to face the world again.

Who would have thought that writing a simple piece of software would turn themselves into criminals!

I don't know how much time passed, a warm hand was placed on Yang Feng's head, but Yang Feng was stunned and buried his head deeper. The smell and warmth are really too familiar, Wang Ziling said softly: "I finally found you." No matter what happens to you in the future, I believe you will always do it well. ”

Yang Feng raised his head, stood up, and shook his hand suddenly: "What am I facing, do you know?—— you don't know!"

The two sides looked at each other for a few seconds, Yang Feng seemed to know that he had done something excessive, Wang Ziling smiled slightly, his eyes smiled into a crescent moon shape, and shook his head: "I really don't know, but I believe that you must be the best person, you are not a person who will back down in the examination room or in the arena." Even if the whole world doesn't believe you, I believe in you. ”

Wang Ziling's words gently made Yang Feng's heart completely melt. Yang Feng pretended to be strong in his heart, and was shattered in an instant, his eyes couldn't hold back tears, and finally fell, while looking at his hands, he said in a voice that seemed to tremble: "I seem to have done something wrong...... I...... It seems to be ...... Doing ...... wrong".

Wang Ziling stepped forward and hugged Yang Feng from the front, and said while stroking Yang Feng's hair, "Okay, okay, don't talk about it." It's okay, it's okay......".

I don't know how long Wang Ziling hugged Yang Feng, and I don't know how many times he said: "It's okay", the black car has been parked not far away, as if there is a pair of eyes watching them on the side of the black window.

【An Internet café in Haierbin City】

"You said that you wanted to take out a loan to build an Internet café, and you would be able to repay us in two months, and you would be able to repay us with interest in three months. But you kid, look at your Internet café, there is no one! The repayment deadline has also arrived, and the daily interest rate is 1 cent, so you can say if you can pay it back! The further you delay, the more you are tired, and we are also tired. A group of debt collectors in black suits are surrounding a young man about 25 years old to collect debts.

This young man is a computer science college student who came to Haierbin to start a business, and he valued the Internet café as a start-up project with enthusiasm, and borrowed 500,000 yuan from the loan company in order to build the Internet café, which was expected to be repaid soon, but the plan was far from changing quickly. In the past, Internet cafes occasionally disconnected, but now even if you reinstall the system on a diskless workstation every night, the entire network will be down the next day.

He has been cornered, and his tired and embarrassed face is the result of staying up late for a long time and fighting the ARP attack virus. He looked up at the rows of empty computers, looked down in frustration and whispered, "I don't have any money......."

The person who took the lead in collecting debts listened to it, and with a "snap", he slapped the young man in the face and said: "There is no money? You treat our money as a strong wind? We have the phone numbers of all the people you know, do you need me to call them one by one and tell them that you are a liar?!", followed by a series of "pop" and "pop" sounds, and then at the suggestion of this person, the group of debt collectors walked out of the door, and before leaving, they did not forget to smash a computer monitor and threatened: " I won't be so polite next time!"

After the group left, the young man who was slumped in a chair smiled and said to himself, "500,000 becomes 1.3 million, haha...... Haha......", and then took out a utility knife from the drawer with a blank face and .......

【Wenjiang Provincial Network Supervision Brigade】

"It's a meeting, everyone pay attention", Captain Sha Ou cleared his throat: "In view of the current outbreak in Haierbin City, Wenjiang Province, the ARP attack technology specifically targeting Internet cafes has been revealed, let's listen to the analysis of Section Chief Zhao of the Technical Investigation Section"

Section Chief Zhao stood up slightly and gestured: "After the analysis of our Technical Investigation Section, the ARP attack technology is carried in a Win32 application with a size of less than 500K, and the attacker mainly exploited Microsoft's MS06067 buffer overflow vulnerability when launching the attack. Because it is in a place like an Internet café, the Trojan virus mainly relies on phishing websites to spread, as long as there is a person in the Internet café ......"

At this time, a person suddenly pushed the door in: "Excuse me, I'm Captain Jiang of the Wenjiang Provincial Criminal Investigation Brigade, and a 25-year-old entrepreneurial young man has just committed suicide......"
