Evidence hunting forensic 4 unsolved case code

After listening to the information compiled by Tang Zhexue in the morning, Lin Dong still said the same thing—stand still, continue to search and arrange, until the lock is locked, no mistakes can be made.

Luo Jianan didn't hear this sentence, but when he heard it, he got kicked again.He was not idle last night, and he took Ou Jian to check the information in the system for Tao Zhihui and Zhou Wei to find out. He was catching up on sleep in the lounge and asked Tang Zhexue to call him before the morning meeting.After reporting work, Tang Zhexue went to the lounge to perform the duty of the alarm clock, but when he went in, Luo Jianan used Ou Jian as a pillow, and the hug was so strong.

Ou Jian didn't fall asleep at all, and he didn't dare to move due to the "pretentious power" of the elder brother, so he could only lie on his side and watch his mobile phone for time.Seeing Tang Zhexue was the same as seeing Avalokitesvara coming, he pointed hard behind him, telling him to call Luo Jianan quickly.

Calculated that Luo Jianan slept for less than two hours, Tang Zhexue thoughtfully said: "Let him sleep again, I'll have breakfast first, the morning meeting starts at 5:[-], just call him [-] minutes in advance."

"I call him?" Ou Jian's expression resembled Edvard Munch's "The Scream", but his voice was as thin as a mosquito, for fear of waking up the living Hades behind him, "Then he can't take all the anger of getting up on me? "

Tang Zhexue squinted his eyes and smiled, and said to himself——yes, your senior brother, why should you take your anger out on me?

He saw Luo Jianan's hand wrapped around Ou Jian's chest slowly curled up, leaving only his middle finger for the two of them.In fact, Tang Zhexue woke up as soon as he opened the door, but he didn't open his eyes.His former undercover career made him sleep very vigilantly, and besides, people coming and going in the lounge, closing and opening doors, no one can sleep well.Gao Ren is the only one who can sleep in this room like a dead pig without the alarm clock waking him up.

Seeing this, Tang Zhexue pushed Luo Jianan's shoulder with his hands: "Get up when you wake up, let's go, go have breakfast, Teacher Qi just went to the office of the unsolved case team to look for you."

As soon as Luo Jianan heard that his daughter-in-law was looking for him, Luo Jianan immediately opened his eyes, sat up and pushed Ou Jian, and said disgustedly: "Stay here, it's preventing me from putting on my shoes."

Ou Jian almost rolled off the bed, he was so wronged—why didn't you think I was in the way when you used me as a pillow?

After brushing his teeth and washing his face, Luo Jianan asked Tang Zhe, who was waiting at the entrance of the lounge, to go to the cafeteria, and asked Lin Dong what he thought of his proposal while walking.Tang Zhexue thought about it for a few seconds, and said tactfully, "The team leader thinks that the evidence is still not conclusive enough, so let's continue to explore."

"I knew he had to say that," Luo Jianan put the corners of his mouth down indifferently, "I checked last night, Tao Zhihui is now the technical director of a technology company, this company is doing artificial intelligence, although I don't understand Computer programs, but those who can do artificial intelligence development are not cowards, right? Technology must be leveraged, isn’t it?”

Because of being suspected of computer technology crimes, Luo Jianan held a temporary hug. Last night, while checking Tao Zhihui's personal information, he asked Ou Jian for advice in a low-key manner, and roughly figured out what Yangkelin was doing these days. What.

Tang Zhexue nodded: "It should be."

Suddenly his shoulders tightened, and he was embraced by Luo Jianan to the corner of the stairs, and he heard the other party whisper: "I see that their company is recruiting Java engineers, and Ou Jian and Yangzi are asked to go for an interview. Programmers are programmers, as soon as you check the depth, you will come out." .”

Undercover?Tang Zhexue frowned and smiled, which was in line with Luo Jianan's behavior style.

At the morning meeting, Luo Jianan mentioned his idea, immediately got Lin Dong's support, and then arranged for Yang Kelin and Ou Jian to send a cover letter to Tao Zhihui's company.As a result, both of them got stuck on their resumes - they couldn't write their resumes working in the Public Security Bureau, let alone write indiscriminately. The responsible HR would call to verify the unit information listed on the resume.

The first thing that needs to be guaranteed when sending an undercover agent out is the credibility of the identity and background information.For example, Luo Jianan's original fake identity was made by Chen Fei himself, and he used the identity of a man named Wang Ping, who was similar in age and appearance, and his relationship was well documented.At that time, the real Wang Ping was dead and had overdosed on drugs. Fade Chen suppressed the news and did not inform his family members, thereby giving Luo Jianan a true and reliable identity information.

The solution is that Lin Dong gave each of them a company name, both of which are technology-based companies they have contacted before: "Write these two companies, and the contact person fills in the phone numbers of me and Team Chen respectively, don't send emails together, Yangzi, You post it in the morning, Xiao Ou, you post it in the afternoon."

The two acted according to orders, but before it was Ou Jian's turn to send out his resume, the call for an interview came to Yang Kelin's cell phone.Poor Yang Kelin, a patient with level [-] social phobia, has excellent skills but is really not good at socializing. He will babble when asked about everything, and his hands are sweaty when he hangs up the phone nervously.He made an appointment for an interview at three o'clock in the afternoon, and Lin Dong asked Luo Jianan to hurry up and train Yang Kelin for two hours, so as not to show his flaws during the interview.

"Then... Team Lin, do you still want to send out my resume?" Ou Jian actually expected himself to be qualified for this task, but the gap with Yang Kelin is also a fact. If Yang Kelin is hired, he will definitely not be able to what's the matter.

"Fat, one more guarantee."

Although Lin Dong also felt that he had no hope, he still had to give the face that should be given.If you insist on making a comparison, Ou Jian is more suitable for special affairs work than Yang Kelin. Yang Kelin's brain is technical and undercover, huh, hasn't he been caught by him once before?

As the interview approached, Tang Zhexue drove Yang Kelin downstairs to the company.Before getting out of the car, Yang Kelin took several deep breaths, and didn't work up the courage to push the door and get out of the car until he saw that the time was about to be late.Before coming here, Luo Jianan told him a lot of precautions, which were engraved in his mind, but the plans often failed to keep up with the changes. After all, undercover black fork organizations and technology companies are two different things.

Yang Kelin was wearing a monitoring device, and after about half an hour, a conversation between the interviewer and Yang Kelin came from Tang Zhexue's earphones.Faced with professional questions, Yang Kelin swept away the stuttering before and answered fluently——

"To solve the communication problem between microservices, please choose two service calling methods and briefly explain the difference."

"Using Dubbo or Springcloud, the difference is that the default Dubbo framework is based on NIO asynchronous transmission, uses TCP long connection and uses Hessian binary serialization to communicate, which has an absolute advantage in performance compared to HTTP protocol, while Springcloud does not limit services. The communication protocol is more compatible."

"Then, to solve the load balancing problem, please list at least three nginx strategies."

"Polling, specifying weight, IP binding Ip_hash, Fair and Url_hash."

Yang Kelin gave the opponent five in one breath.Although Tang Zhexue did not understand technology, he reckoned that the interviewer would not be dissatisfied with such a fluent answer. It seemed that Ou Jianfa's resume would be lost forever.

The interviewer asked ten questions one after another, and then told Yang Kelin to wait a while, saying that the company's technical director would come over for the final interview.The technical director is naturally Tao Zhihui, which is a surprise, so there is no need to join the company.Tang Zhexue informed Yang Kelin through the earphones that he would try his best to do the research during the interview stage.

The following conversation between Tao Zhihui and Yang Kelin sounded like a bible to Tang Zhexue.The communication between technicians is like codes. Some words cannot be translated in the translator.Yunshan listened in a fog for half an hour, and he was suddenly attracted by Yang Kelin's words: "My salary requirement is 50K."

This is a solid code, and the lion opened his mouth wide, indicating that the moping work is over.

Tao Zhihui’s tone came out from the earphones completely different from when he talked about technology just now: “50K? This has to be the salary level of a senior architect in a big factory. We are a startup company. Although your technology is very good, I’m sorry, we can’t afford you.” You are such a high-end talent."

"Well." Facing the refusal, Yang Kelin, as always, didn't have any words to bargain or argue for himself, and got up directly, "Then, I'm leaving, thank you."

"Wait a minute," came the sound of chairs, footsteps, and a lower volume than before, "Although the company can't afford you, there are some other jobs that we can cooperate with. I will send you a project later. Take a look at the demand list, if you are willing to do it, you can get this amount."

"12?" Yangkelin said while adjusting the position of the earphones to send a signal, and nodded after receiving instructions from Tang Zhexue, "Okay, send it, I'll think about it."

When Yang Kelin came out of the office building and got into the car, Tang Zhexue immediately asked, "Is that him?"

After pondering for a few seconds, Yang Kelin shook his head: "From a technical point of view, Tao Zhihui's application is very good, but I just asked him a few questions about 0day vulnerabilities, and his feedback did not fully grasp the key points, so, take From my experience, he couldn't write that kind of embedded virus."

This answer made Tang Zhexue feel mixed. He is happy that Tao Zhihui may be cleared of suspicion because of this, but worried that the investigation of the case may go around in circles again.At the same time, Yang Kelin’s mobile phone received an email sent to the private mailbox where he submitted his resume. After clicking on it, he immediately reached out and tugged on Tang Zhexue’s sleeve: “Vice-team vice-team! Look at this mailbox number.” !"

Tang Zhexue took a closer look and found that it was [email protected].

Let's just say, the brain circuit of this scumbag technician is really beyond the reach of me and other scumbags. Just check the interview questions, and it's over if you say what I wrote is right or not.
