Chapter 36: The Dinner (5) The Hacker's Counterattack

Zheng Xiumin was so frightened that she couldn't say a word, and was at his mercy.

The elevator door opened with a clang, and there was a naked man with a wooden stick with a thick arm and smashed over, it turned out that there were ambush soldiers, Qi Na knew that this person was staring at the sneak attack on the second floor, and when he saw them escape, he ambushed them.

But this person thought that Qi Na's nerves reacted quickly, more than dozens or hundreds of times faster than ordinary people, and at this moment, Qi Na raised his long legs and kicked at this person's chest.

Qi Na is one meter nine tall, this person is only one meter six, plus this person's center of gravity is all in the lower plate, his body is low, and his chest is just under Qi Na's sole, he is like a speeding car being hit by an oncoming obstacle, and the lower plate is like taking off, unhindered force, and then the whole back falls to the ground heavily.

The man screamed after he landed, and I don't know if it was the pain of falling on his back, or the pain of being kicked in his chest.

Qi Na pulled Zheng Xiumin and walked out, at this time Wanda's security guard had arrived when he heard the news, Qi Na's heart suddenly settled down, he pulled Zheng Xiumin like a security guard asking for help, and the security guard kept to control those thieves.

Someone from the surrounding merchants saw that Zheng Xiumin was drenched with half of her body, and brought her a towel and a T-shirt.

Qi Na saw that someone was taking photos and videos with his mobile phone, and it is estimated that someone will upload a video later, with a title: The junior in the downtown was violently beaten and poured gasoline.

He pulled Zheng Xiumin to hide around the corner to avoid the gossipy passers-by.

The police also rushed over after receiving the alarm, only the thief at the elevator entrance was caught, and the other two thieves were long gone.

In the police station

The police asked Zheng Xiumin why he was chased and killed, and if he had a vendetta with someone outside?

Qi Na had been thinking about what the reason was for a long time, and after thinking about it, it could only be Long Shi'an, so the police asked, and Qi Na replied no, and he didn't understand what the reason was.

The policeman glared at Qi Na, and the frightened Zheng Xiumin's mind was in a mess at this time, and she nodded whatever Qi Na said.

And the short thug who met at the elevator entrance was also gritting his teeth, and when he was in a hurry, he said that he was out of love, and when he saw Qi Na and Zheng Xiumin tired of being together, he was irritated and did it.

The police are not fools, since the victim is silent, it is obvious that there is a reason for the incident, then the police also recorded a confession and walked out of the square.

In the end, the two sides reached a verbal agreement, the short one compensated Zheng Xiumin 10,000 yuan, and he went to the hospital for his own injuries.

Qi Na and Zheng Xiumin were waiting at the police station, and the security guard of the police station accompanied the short man to get the money and handed it back to Zheng Xiumin, so that the matter was over.

At this time, it was already twelve o'clock, and all the time spent at the police station was wasted all night.

Zheng Xiumin had already recovered from the state of shock just now, and said to Qi Na: "If it weren't for you, I'm afraid I'd be finished." ”

She thought about the gasoline sprayed on her face just now, as long as there was a cigarette butt, her life would be over. The only one who wants to do this kind of thing is the pervert named Long Shi'an.

Qi Na shook his head and said, "If it weren't for me, I'm afraid you would have met Long Shi'an Pingshui, and there would be no later and today's events." ”

Zheng Xiumin sighed: "You are wrong, since this person can be so vicious, I will not end well in my relationship with him." Both times it was a loss to you. Thank you so much. ”

Qi Na said: "Don't thank you, fortunately nothing happened, otherwise I wouldn't be able to explain it to your family." ”

They all knew that Lu Dao must have been instructed by Long Shi'an to commit murder, but the current situation is that if he continues to have a bad relationship with Long Shi'an, such villains are not something ordinary people can afford to provoke, and if he changes his target and murders Zheng Xiumin's parents, what will he do?

So Qi Na suppressed everything as soon as he faced the police.

Zheng Xiumin is not a flower in a greenhouse, she is still two years older than Qi Na, so she naturally understands what Qi Na means, but they don't know if Long Shi'an can appreciate it. Her emotions grew more and more tense.

Qi Na comforted her: "Look, we didn't see the movie twice, it seems that the movie theater really has a magnetic field absorbing our character." ”

Zheng Xiumin smiled, finally stopped a taxi, got into the car together, Qi Na sent Zheng Xiumin home, watched her enter the gate of the community, and then let the driver turn around and leave.

When Zheng Xiumin returned home, she didn't dare to tell her family what happened, so she thought about safety, thought about it, and sent a text message to Qi Na, saying: I will call my aunt tomorrow to find out the situation, and then I will simply go to Shanghai for two days to avoid the storm.

In fact, she wanted Qi Na to accompany her, but after all, she had only met three times, although there were two not very beautiful episodes, and the two became more and more familiar, but she still couldn't open her mouth, and she felt a trace of fear when she wanted the two of them to be alone, so she gave up this idea.

Also, grandma still needs to be taken care of in the hospital, and if she leaves, the pressure on her parents will be even greater, but she can't take care of so much in front of her, but fortunately, grandma is in stable condition and will be discharged from the hospital in two days.

Qi Na immediately replied: This arrangement is very good.

Then he replied: Wait for you to come back and watch the movie.

On the way home, Qi Na was also thinking about how to live peacefully with Long Shi'an, but obviously things were not as simple as they imagined. Telling the police will incur greater retaliation, and not telling will lead to greater uncertainty.

He has always pursued a wise posture of protecting himself, but today's thing is for Zheng Xiumin, he is going to be a turtle with a shrunken head, I'm afraid he will look down on himself.

Du Fu's poem says that the thief captures the king first, and Sun Tzu's Art of War says that knowing oneself and knowing the other is invincible. So you have to get to know Long Sai An first. in order to have a purpose.

Qi Na had this person's ID information and a phone number, and these two things were enough for him to investigate a person.

The taxi passed by the Ningnan Police Station building, Qi Na stopped the taxi, got out of the car and walked around the police station office building twice, and finally found the weak Wifi signal from the building, and connected to this Wifi network, he saved the effort of attacking the internal network of the police station on the Internet.

And as far as he knows, the police station's network is isolated from the internal and external networks, and even if it is easy to enter the official site of the police station, it is almost impossible to enter the core database.

But if you want to find out the real valuable personal information of a stranger, you can only find out in the core database of the police station.

This is a huge challenge, especially when you think about the backbone firewall outside of the core database.

Even Qi Na will not be able to break through these firewalls in a short period of time.

Although the difficulties are enormous, it is simply an impossible task.

But Qi Na is a character who is good at maneuvering, he will always have some amazing skills, for hackers, maybe not pure skills, but belong to another category outside of skills - social workers! That is, social engineering.

In short, it is the social behavior that everyone sees, finds loopholes in it, cracks it, and attacks.

So he came to the surroundings of the police station building, in the thin wifi network, Qi Na's information was wandering, and the incredibly powerful police station core database firewall was high above, it seemed to be a giant, contemptuous of the small water pipe-like WIFI channel, and Qi Na inside.

Qi Na unhurriedly released a large number of robots in the Wifi network of the police station, that is, the kind of web spiders used by search engines, or web crawlers.

Of course, search engine web bots have certain rules of conduct and are restricted. Searching for voluntarily disclosed data only within a certain range is like every website has a rule, within which the data bot can retrieve and collect, but the search engine's bot will not touch it.

On the other hand, Qi Na's cyber robots are not bound by these moral requirements, they are set by Qi Na, they only follow this strategy, and act according to Qi Na's requirements.

Qi Na first understands the structure of the police station's Wifi network, then understands what devices are on the Wifi network, and then where these network devices can be linked.

The Wifi network is only convenient for the officers and officers working in the police station to access the Internet on their mobile phones, tablets or laptops, and does not intersect with the police station intranet and core data, but in the process of using these devices, there will always be people who inadvertently serial the two networks together, such as a wireless wifi, a wired Lan, although the software is not interconnected, but the physical connection exists, so the opportunity for Qi Na came.

After Qi Na found such a path, he then released the second batch of cyberbots, this time looking for Long Shi'an's personal information and information related to him.

Although the firewall retrieves abnormal data, the data is released in the intranet and is not within the scope of firewall protection, so the firewall does not prevent it. In an instant, Qi Na dominated the core database of this huge body that was high above.

The core computer room of the police station has rich interfaces, and it is even linked to the computer rooms of China Mobile, China Unicom, and Telecom.

Then the comparison was carried out, and the fourth batch of network robots was released to continue to collect data.

Then there are the real estate centers, the banking network...............

Obviously, Qi Na took Long Shi'an as a target, and with him as the center, he weaved a huge schematic diagram of the interpersonal relationship and communication network.

This schematic diagram is so huge that Qi Na has to draw it in 3D, and the second dimension cannot be interpreted at all.

Tossed back and forth for four hours, until a passing patrol found him, and Qi Na said it was waiting for someone, so he disconnected the Wifi in the police station building. Turn away.

Those patrol officers looked at Qi Na's back and thought that this was a strange person, but they knew that the whole person had just hacked into their internal core data network, and unknowingly caused a major information and data leakage accident.

But no one knows the way, and no one knows the way.

It's as if nothing happened, except for the hot body of the Wifi router that worked hard for four hours.

When I got home, it was already dark, Xiaoxue had just gotten up, sleepy-eyed and was washing rice and cooking porridge, and was startled when she saw Qi Na coming in.

Qi Na grimaced at her and returned to her room. He has to seize the time to sort out this huge amount of data, strive to find clues, and then fight back against Long Shi'an in a targeted manner.

Long Shi'an was sleeping soundly with a girl in his arms, and was woken up by his phone, singing K all night last night, and then eating a hot pot early in the morning, the fire was booming, and the girl he was looking for in the song hall to sleep with him until now, he was still sleepy in a daze, and scolded when he answered the phone.

His younger brother told him that Zheng Xiumin, who was being monitored by them, had gone to Shanghai and should follow him. Long Shi'an said a few words, suddenly came to his senses, and scolded: "She is running away, Shanghai is not our territory, let her go, I don't believe she won't come back." Let him escape last night, I don't believe he will have such good luck next time. And the man who was with him, did you find out? ”

Hearing the negative answers of the younger brothers, Long Shi'an scolded, took out a cigarette, touched the lighter, and took a deep breath. Then he scolded: "Sooner or later, Lao Tzu will kill that forced raiser." ”

What Long Shi'an said is Qi Na, but it's a pity that Qi Na always acts carefully, his little brothers and Ma Zai are all little ruffians who are amateur guest detectives, there is a way there!
