Need for little hackers

Chapter 26 Dinner ([-]) The Hacker's Counterattack
Zheng Xiumin was so frightened that she couldn't say a word, and she let him manipulate her.

The elevator door opened with a ding-dong sound, and a man with a bare upper body was smashing towards him with a wooden stick with a thick arm. It turned out that there were still ambushes. Qina knew that this man was watching the sneak attack on the second floor, and when he saw them escape, he took advantage of it Ambush.

But this person thought that Qina's nerve reaction was quicker than ordinary people's, and it was more than tens or hundreds of times faster. At this moment, Qina raised his long legs and kicked the man's chest.

Qi Na is 1.9 meters tall, and this person is about 1.6 meters tall. In addition, this person's center of gravity is all on the lower body, his body is lowered, and his chest is just under the soles of Qi Na's shoes. He is like a speeding car being hit by an oncoming car. The obstacle hit straight, and the lower body seemed to be flying into the air, without any blocking force, and then the whole back fell heavily to the ground.

After the man fell to the ground, he let out a shrill scream. It was unknown whether it was the pain from the fall on his back, or the pain in his chest from being kicked.

Qi Na pulled Zheng Xiumin and walked out. At this time, Wanda's security guards had arrived, and Qi Na's heart immediately settled down. He pulled Zheng Xiumin like a security guard asking for help, and the security guards went to control the thieves non-stop.

Someone from the surrounding merchants saw that half of Zheng Xiumin's body was drenched, and brought her a towel and a T-shirt.

Qi Na saw someone taking pictures and videos with their mobile phones, and guessed that someone would upload the video later, with a title: A young man in a busy city was violently beaten and doused with gasoline.

He dragged Zheng Xiumin into a corner to avoid gossip passers-by.

The police also rushed over after receiving the alarm. Only the thieves at the elevator entrance were caught, and the other two thieves had long since disappeared.

In the police station

The police asked Zheng Xiumin why he was hunted down, did he make enemies outside?
Qina had been thinking about the reason for a long time, and after thinking about it, it could only be Long Shi'an, so the police asked, and Qina quickly answered that there was no reason, and he didn't understand the reason.

The policeman glared at Qi Na, and Zheng Xiumin, who was still in shock, was in a state of confusion at this moment, and she nodded at everything Qi Na said.

And the short thug who met at the elevator entrance also gritted his teeth and said that he was broken in love when he was so anxious.

The police are not fools, since the victim did not say anything, obviously there was a reason for the incident, so the police also took a statement and walked out of the square.

In the end, the two sides reached a verbal agreement, the short one compensated Zheng Xiumin 1 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 at the police station accompanied the short guy out to get the money and hand it back to Zheng Xiumin, so that the matter was settled.

It was already twelve o'clock at this time, and the whole night was wasted in the police station.

Zheng Xiumin had already calmed down from the state of shock just now, and said to Qi Na: "If it weren't for you, I'm afraid I would be doomed."

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 such a thing is that pervert named Long Shi'an.

Qina shook his head and said, "If it weren't for me, you might just meet Long Shi'an by chance, and there wouldn't be what happened later or today."

Zheng Xiumin sighed: "You are wrong. Since this person can be so vicious, I will not end well when I date him. I lost you both times. Thank you very much."

Qina said: "Don't thank me, luckily nothing happened, otherwise I wouldn't be able to explain to your family."

They all knew that Long Shi'an must have instigated the murder, but the current situation is that if they continue to fight against Long Shi'an, such a villain is not something that ordinary people can afford. If he later changes his target and attacks Zheng Xiumin's parents , what should I do?
Therefore, when facing the police, Qi Na immediately suppressed everything.

Zheng Xiumin is not a flower in the greenhouse either, she is two years older than Qin Na, so she naturally understands what Qin Na means, but they don't know if Long Shian can appreciate it.Her mood grew tense.

Qi Na comforted her: "Look, we didn't watch the movie twice. It seems that there is indeed a magnetic field in the movie theater that is absorbing our character."

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

When Zheng Xiumin got home, she didn't dare to tell her family what happened, so she thought about safety issues, 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 to play for two days to avoid the wind.

In fact, she wanted Qi Na to be with her more, but after all, she had only met three times. Although there were two unsatisfactory episodes, and the two became more and more familiar, she still couldn't open her mouth. Feeling a tinge of fear, I dropped the idea.

Also, grandma is still in the hospital and needs someone to take care of her. If she leaves by herself, the pressure on the parents will be even greater, but they can't care about so much now. Fortunately, grandma's condition is stable and she will be discharged from the hospital in two days.

Qi Na replied immediately: This arrangement is very good.

He then went back: Waiting for you to come back and watch a movie.

On the way home, Qina was also thinking about how to coexist peacefully with Long Shian, but apparently things were not as simple as they imagined.Telling the police invites greater retaliation, not telling the police creates greater uncertainty.

He has always pursued a stance of being wise and protecting himself, but today's incident is aimed at Zheng Xiumin, if he wants to be a coward, he may even look down on himself.

Du Fu's poem said that the king should be captured first when capturing a thief, and Sun Tzu's Art of War said that knowing yourself and the enemy will never imperil you in a hundred battles.So we must first understand Long Shian.In order to be targeted.

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

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

And as far as he knew, the police station's network was isolated from the internal and external networks. Even if you easily entered the police station's official website, it was almost impossible to access the core database.

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

This is a huge challenge, especially when you think of the backbone-level firewalls outside the core database, which is especially frustrating.

Even Qina couldn't break through these firewalls in a short time.

Although the difficulty is huge, it is simply an impossible task.

But Qi Na is a character who is good at maneuvering, and he always has some amazing skills. For hackers, it may not be purely technical, but it belongs to another category besides technology-social work!That is social engineering.

In short, it is the social behavior that everyone sees, from which loopholes are found, cracked and attacked.

So he came around the police station building. In the thin wifi network, Qi Na's information was lingering, and the incredibly powerful firewall of the police core database seemed to be a giant. accept.

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, the web robots of search engines all have certain codes of conduct and are bound by them.Only search for voluntarily disclosed data within a certain range, just like every website has a rule, the data within this rule can be retrieved and collected by web robots, in addition, the web robots of search engines will not touch touched.

However, Qina's network robots are not bound by these moral requirements. They are set up by Qina with a strategy, and they only follow this strategy and act according to Qina's requirements.

Qi Na first understood the structure of the police station's Wi-Fi network, and then understood what devices were on the Wi-Fi network, and then where these network devices could be linked.

The Wifi network is only convenient for the police officers who work in the police station, and the police officers use their mobile phones, tablets or laptops to access the Internet. It does not overlap with the police intranet and core data. The networks are connected in series, such as a wireless wifi and a wired Lan. Although the software is not connected to each other, the physical connection exists, so the opportunity for Qi Na comes.

After finding such a path, Qi Na released the second batch of network robots, this time looking for Long Shian's personal information and information related to him.

Although the firewall retrieved abnormal data, the data was released from the intranet and was not within the scope of the firewall's protection, so the firewall did not prevent it.In a blink of an eye, Qina dominated the core database of this tall and huge body.

The core computer room of the police station has rich interfaces, and it even links to the computer rooms of China Mobile, China Unicom, and China Telecom. Qi Na continued to work hard and released the third batch of network robots to copy all the communication records of mobile phone numbers, including SMS records.

Then compare and use this cross data to release the fourth batch of network robots to continue collecting data.

Then there is the real estate center, the bank network…………

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

This schematic diagram is too huge, so that Qi Na had to use 3D to draw it, and Two-dimensional cannot explain it at all.

After tossing and tossing for four hours, it was not until a passing patrolman found him, and Qina said he was waiting for someone, that he disconnected the Wi-Fi in the police station building.Turn around and leave.

Those patrolmen looked at Qi Na's back and thought he was a weird person, but they didn't know that just now they invaded their internal core data network and unknowingly caused a major information and data leakage accident.

But no one knows, and no one ever will.

Everything seemed to have never happened, only the hot body of the Wifi router that worked under high load for four hours was different from usual.

Back home, it was already dawn, Xiaoxue just woke up, she was washing rice and cooking porridge sleepily, when she saw Qi Na come in, she was startled.

Qina made a face at her and went back to his room.He must seize the time to sort out the huge data, try to find clues, and then attack Long Shi'an in a targeted manner.

Long Shi'an was sleeping soundly with the girl in his arms, and was woken up by his subordinate's phone call. He sang K all night last night, and then ate a hot pot early in the morning. , Cursed after answering the phone.

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

Hearing the negative answers from the younger brothers, Long Shi'an cursed, took out a cigarette, touched the lighter, and took a deep breath.Then he scolded: "Sooner or later, I will kill that forced child."

What Long Shi'an was talking about was Qi Na, but it's a pity that Qi Na always acted cautiously. His younger brothers and horse boys are all amateur detectives, there is a way!
