Into Unscientific

  Chapter 76 The Faint Watch

   "What? Someone asked you to buy samples of gel baits?"

  In the Office of the Dean of the School of Life Sciences.

  Tian Liangwei looked at Chang Licheng solemnly, with a serious expression.

   An hour ago.

  After realizing that something was wrong with Wang Zhaomin's actions, Chang Licheng immediately reported the situation to Xu Yun, who was quickly taken to the dean's office by Xu Yun.

  Although Tian Liangwei is not the dean of his family, Chang Licheng still feels a little uncomfortable with the title of an academician.

  I saw him shrink his neck and said:

   "That's right, that person hasn't contacted me for a long time, and I didn't expect to chat with me about what happened last night suddenly today.

  Actually, I didn't pay much attention to it at first, but when he said that he wanted to spend money to buy glue bait, I felt a little strange.

  Yanjing is located in the north, and cockroaches are relatively rare, let alone the American cockroach, which is mainly distributed in the south.

  And speaking of closeness, there are at least five people in our major who are more familiar with him.

  For example, Wang Siyuan, who is in the next class, is still from his hometown, so why should he not contact me?

  So the more I thought about it, the more something went wrong, so I found it at Xushen’s place.”

   "You're doing the right thing."

  After he finished talking about the cause and effect, Tian Liangwei affirmed:

   "This situation does not make sense logically. It is probably because the other party has been in Luzhou for a long time in the past few years and has a relatively stereotyped impression of cockroaches.

   As a result, he went to Yanjing recently, and he couldn't see any cockroaches around, so he put an inherent template in his expression, and finally exposed his stuff.

   After all, according to what you said, that Wang Zhaomin was just an ordinary advertising student from another school before, so maybe some of his words are not so rigorous.

  Of course, it cannot be ruled out that the other party did see some American cockroaches.

  Although the American cockroach is rare in the north, it is not completely extinct.”

  Thinking of this, Tian Liangwei turned to look at Xu Yun, and asked:

   "Xiao Xu, what do you think?"

  Xu Yun pondered for a moment, glanced at the computer on the table, and said:

   "Why don't you ask Director Wang Qingchen of the Internet Information Center to take a look? First confirm the location of the other party?"

  Tian Liangwei smiled and pointed at him with his index finger, looking very happy:

   "Xiao Xu, we want to go together."

  University of Science and Technology of China is the most popular school in China. In addition to being criticized by people with ulterior motives in public opinion, the confrontation that has happened or is happening in the field of network security is often countless times more than the public opinion side.

  Therefore, although the University of Science and Technology started relatively slowly in computer science, it was separated from the Faculty of Letters and became an independent computer college very late.

  But at present, in terms of network security capabilities alone, except for the four local universities, Shanghai Jiaotong University, Zhejiang University, Beiyou University and Shuimu University, almost no one can say that they are better than HKUST.

  As the top leader of HKUST's network security, Wang Qingchen's resume and ability are naturally extraordinary.

  He, like the previous Zhang Rui, graduated from the mysterious Krypton Gold Academy of Zhang Shuo University.

   Former deputy director of the Institute of Information Technology, Chinese Academy of Sciences, one of the first batch of top experts in cyber security in China.

   In addition, Wang Qingchen was once one of the top seven legends of the Hongmeng. He fought side by side with Lion and Binger many times, and was the real main member of the battle in 2001.

  Later, the Red League was disbanded for some reason, and Wang Qingchen was hired by HKUST as the director of the Internet Security Department at the end of 2013, and began to **** the growth of the next generation.

  After receiving Xu Yun's notice, Wang Qingchen rushed to the scene quickly.

  The appearance of the head of the University of Science and Technology Network Security looks to be in his early forties, around 175, with a relatively thin body, and his hair is very thick and anti-human.

  After arriving at the office, Wang Qingchen first greeted Xu Yun with familiarity:

   "Academician Tian, ​​Dr. Xu, long time no see."

  Xu Yun and Tian Liangwei nodded to Wang Qingchen successively, and then Xu Yun described the situation Chang Licheng encountered in detail:

   "Director Wang, can you roughly locate the other party's IP or information when you only know the other party's Penguin number?"

  Wang Qingchen thought for a while and replied:

   "It's very simple to query the IP, as long as the other party is not a top hacker, even if you use a CDN, it's not a big problem. As for personal information.

  Dr. Xu, this may require an application for the official department to connect to the Internet. After all, we can’t do things that break the law.

  Of course, if our University of Science and Technology really wants to investigate, the procedures will not be so cumbersome."

  Hearing this, Tian Liangwei couldn't help but exchanged glances with Xu Yun, his expression was a little strange:

  The truth is this, but why does it feel weird to say the words of obeying the law from the mouth of this old black who participated in the battle in 2001?

  It’s like a well-known pigeon who suddenly said righteously that everyone should live up to the expectations of the readers.

   Then Tian Liangwei forced himself to dispel the sense of disobedience and asked:

   "Since it's such a personal information matter, let's leave it alone, Director Wang, can you lock his IP first?"

  Wang Qingchen smiled shyly, not seeing the publicity of the red guest at the beginning:

   "For small things, if there is only one QQ number, it may be more troublesome to check, and it will not be so accurate without the assistance of the operator.

   But since the other party just chatted with our people not long ago, it is much easier to lock it, just check it directly through the two-way communication protocol.

  Even if the opposite side passes CDN acceleration, the second-level domain name method and nslookup method are theoretically sufficient.

  After all, according to what you said, there is a high probability that the other party is a half-baked guy who has just been recruited, and now I guess he hasn't realized that he has been exposed. "

  Seeing Wang Qingchen's understatement, Xu Yun and Tian Liangwei, two computer noobs who couldn't even tell the difference between graphics cards, immediately felt relieved.

   Then Wang Qingchen opened the notebook he had brought, and let Chang Licheng board the Penguin.

   "Applied Physics Class 2 Class Group. The 21st freshman exchange group of HKUST, Jiaran, I like you so much, Qiu Mingshan Old Driver Gathering Club** Club."

  After publicly executing Chang Licheng's penguin group, Wang Qingchen finally turned to the previous chat records, and began to fiddle with them.

   Half an hour later.

  Wang Qingchen clapped his hands together and made a gesture like an earth-shattering star:

   "OK, done, the opposite ip is 202.106.xxxxxx

  This is a community broadband, near Dahongmen, South Fourth Ring Road, Yanjing. "

  Xu Yun stroked his chin thoughtfully, and said:

   "It's really in Yanjing. Director Wang, what should we do next, do we need to contact other departments to assist in the investigation?"

  In Xu Yun's view, once the other party's IP is locked, as long as he learns about the other party's recent movements or financial transactions through channels, he can probably be sure about the matter.

  However, to his surprise, Wang Qingchen shook his head:

"no need."

  Xu Yun blinked, not knowing why:

  “.Huh? Why?”

  Wang Qingchen pointed to the screen, with an expression of 'you don't think I locked an ip in half an hour':

   "It's like this, I paid special attention to the relevant information of this place, and finally found that .

  The Internet portraits of the residents in the area highly overlap with a certain enterprise, including not limited to the nodes that are disconnected from the Internet every day, the wifi connected to the Penguin during working hours, etc.

  At the same time, the factory area of ​​that company is also very close to this area, so it can be roughly judged that it is a dormitory building of a company. "

   "What business?"

   "Let me take a look.

   Well, it is a foreign company.

  The full name is Morishita Co., Ltd., and the Chinese name is Morishita Pharmaceuticals. It mainly produces pesticides and the processing of related derivatives. "

  Here is a trick building, if you want to play tricks, you can leave your name, gender, age, identity, and you can spoil it, you can leave your local ancient identity.
