"I mean, you don't want to fish, do you? Is it necessary for me to do this kind of thing? Your police don't have more tools, but they are reasonable and legitimate. Tycho looked at Wen Qiao with a wary expression.

"You have an advantage that the police don't have."

"Really?" Tycho had just suffered a defeat in the duel with Liu Mengwei, and when he heard Wen Qiao's praise, he couldn't help but feel beautiful again: "Then you come and listen." ”

Wen Qiao was not used to him, and said solemnly: "Now that a female student is suspected of disappearing, of course the police can file a case according to the process, apply, approve, and then find out her location, and in the end it may be found that it is just a false alarm, but it may also be powerless." And if you can find it a few hours in advance, maybe there is room for redemption. ”

Tycho finally put away his cynical appearance and returned to the computer, his flexible fingers fluttering on the keyboard, but he still refused to spare him easily: "It's hard to say whether this person has been kidnapped or not, anyway, I was kidnapped by you, moral kidnapping!" ”

Halfway through the knock, Tycho turned around and said solemnly to Wen Qiao: "However, we said in advance, the responsibility for today's matter lies with the two of you, and it has nothing to do with me, I was coerced!" ”

With the development of information technology, a discipline called social engineering has been derived, and social engineers are good at gathering all kinds of resources and ways that you can think of and unexpected to dig out the information they want. Social workers in the hacking field will use the network to expose resources and at the same time use human weaknesses to intervene in their psychology to achieve the purpose of invading the system. These weaknesses can be inconspicuous and unnoticed details, such as personal information and data thrown around, contract agreements or authorizations that are checked when logging in to the app, and the use of the same password on each website software. Today, social engineering attacks are one of the top cyberattack methods. Software engineers can build a rigorous and secure system, and regularly patch the system to plug all kinds of new security vulnerabilities, but no matter how secure and reliable a system is, it faces one of the biggest threats, that is, its users, and human vulnerabilities are always the easiest to breach.

The hackers consolidated and analyzed the leaked user data and archived it in a database called the Social Worker Database. The personal privacy information of thousands of ordinary people is stored in the social worker database, and in the era of Internet big data, everyone is "running naked".

After about half an hour, a map appeared on Tycho's computer screen, and he frowned and looked at it for a long time, and finally said: "Through the triangulation of the mobile phone signal, it is preliminarily determined that the holder of this number should now be near a county town called Mengla in Banna, and check in at a hotel called the Red Leaf Hotel with his ID card." It looks quite normal, is she going on a trip? ”

Wen Qiao went through the information he had derived. "Didn't you see the problem?"

"What's the problem?"

"How did she get to Banna? You can check her recent check-in records, but you don't find any travel information, train tickets, plane tickets are not recorded, she seems to appear there out of thin air. ”

"Can't you just drive yourself? Or carpooling with others, which is also popular these days. Tycho didn't think it was suspicious. If you want me to see, people are just going out to travel. Her phone is on normally, there are occasional calls, and she also posted a few photos on social platforms yesterday. It's okay to look at it, are you thinking too much? ”

It's true...... It's just that they think too much? If this is the case, of course it is best, but Wen Qiao always felt that something was not quite right, and he couldn't find it for a while. He was about to turn around and ask Liu Mengwei to come and see, but found that she was already half-leaning on the leather sofa next to her, and it seemed that she was asleep.

Tycho also glanced over there with his eyes, consciously or unconsciously, Liu Mengwei had already wiped off the thick ink on his face, revealing a clean and fair face, and his soft and thick black curls were scattered casually, like a quiet and docile sheep.

Tycho muttered, "It's much more pleasing to the eye." Then he touched Wen Qiao with his elbow again, and said with a wicked smile: "Honestly, what is the relationship between the two of you?" ”

"It doesn't matter." Wen Qiao's face was expressionless.

"I'm risking such a big favor for you, and you even have to hide this little thing from me!"

Wen Qiao glanced at him and said indifferently: "If you have to say that it has anything to do with it, it's almost the kind of relationship between you and me." ”

Tycho instantly distanced himself from him, and crossed his arms in front of him: "Don't talk nonsense, what do I have to do with you?" This is only the third time we've met! ”

"That's true, we don't see each other much, if I have to describe this relationship...... Wen Qiao paused, thought for a moment and said: "You are professional, have high use value, controllable danger, unknown details, and can be partially trusted...... Acquaintances. "Yes, between them, I'm afraid they can't even reach the word friend.

When Tycho heard this, his mouth was open enough to fit an egg, and he stayed for a moment before he said, "I almost have a kind of admiration for you, brother." I always thought that our tech nerds were the most rigorous and rational group in the world, the closest to robots, but I didn't expect to meet you today, and I was really willing to bow down. ”

"I'm telling the truth." Wen Qiao said seriously.

"Indeed," Tycho pouted, "I've never heard anyone make up a lie so sincerely." But you're too honest! I'd love to wake her up and ask her how she feels, and I'm afraid she'll be very disappointed. ”

"Don't talk nonsense, even if you ask directly, her answer should be similar to mine."

"Really?" Tycho approached Wen Qiao again with bad intentions, "You guys were holding hands when you entered the door just now, don't think I didn't see it." Today, the head of my FFF regiment must seriously judge you dulicitous and pretentious men and women, do you dare to make a bet with me? ”

"No, I don't like to bet with people."

Tycho was anxious: "Why are you so boring, you have to bet with me, I have to get a game back." It turned out that he was still thinking about the defeat just now, and he was holding his breath in his heart.

Wen Qiao was helpless, so he had to follow his words: "You have already broken the vows today anyway, so it is better to help me check one more person." Wen Qiao took the opportunity to bargain with him: "I owe you a favor." ”

Tycho shouted in a suppressed voice: "I can see it, you are not willing to suffer a little loss, you must have been a black-hearted capitalist in your last life!" The ability to make inches of progress has been perfected! ”

"Didn't I write down a favor account for you?" The most difficult thing to repay is the favor account, Wen Qiao regretted it a little after saying this, anything that happened today, in fact, there is no need for a forensic doctor from the criminal police team to be responsible, this is probably being confused by ghosts.

Tycho said disdainfully: "Cut, what's the use of your favors?" ”

Wen Qiao thought for a while, and solemnly promised: "If you are kidnapped or threatened by your life in the future, I will try my best to save you." ”

Tycho's face was blue and red for a while, and his expression froze on his face, and he couldn't laugh or cry: "What are you talking about?" If something happened to me, you should have saved me, you're a policeman, big brother! ”

"If it happened in another jurisdiction, it had nothing to do with me."

"You! Would you like to hear what you're talking about? How can a 37-degree mouth say such cold words! ”

"I thought you had this kind of realization."

Hearing this, Tycho was stunned, and then turned his head a little lonely.

"Haha, that joke wasn't funny at all." Tychopi said with a smile, but his heart was still a little touched, he thought that there would be a certain risk in doing these things, but he never thought about what to do if this risk really happened to him.

"The world is far more dangerous than you think." Wen Qiao reminded.

Tycho gave him a blank look, "Do you still need to say this?" ”

His eyes sparkled like distant but bright stars in the night. "If I had been afraid, I wouldn't have done it in the first place. After all, your regular army has a limited number of people, and many times you can only catch the big and let go of the small, dancing in shackles. But we're different, no one asks us to do it, but when you have the ability, how can you resist using it? My conscience restricts me from using it to hurt people, so I use it to help people and fight against darkness. I am very happy to be a useful person, every time I defeat those rats and bugs hiding in the dark corners, I feel extremely happy, which is the satisfaction that nothing else can bring me, you should know how difficult it is for a person to find something to fight for, from which strength can be drawn, and even happiness and happiness, right? A lot of people just live and I'm lucky. ”

He patted Wen Qiao on the shoulder, "I have a lot of like-minded friends like this, but I have never met, we do everything by heart, but this line of work has been done for a long time, and I also deeply understand that the most unreliable is the human heart." So, Brother Tiaozi, you have to help me guard the door. ”。

Wen Qiao was speechless for a while, his face was as cold as a glacier in Antarctica, and his heart suddenly had a mess of hemp rope that was getting more and more chaotic.

Seeing his extremely serious expression, Tycho chuckled a few times, and deliberately showed off lightly: "Don't worry, nothing will happen to me, it's a big deal that Lao Tzu won't wash his hands and go home to inherit Dad's billions of family property!" ”
