Chapter 74: The faint gaze (Thanks to the second leader who let go of the female monkey boss!!)
"What? Someone comes to you and wants to buy a sample of gel bait?"
Inside the Office of the Dean of the School of Life Sciences.
Tian Liangwei looked at Chang Licheng solemnly, his expression quite serious.
an hour ago.
After noticing something was wrong with Wang Zhaomin's behavior, Chang Licheng immediately reported the situation to Xu Yun, and was quickly taken to the dean's office by Xu Yun.
Although Tian Liangwei was not the dean of his family, the title of an academician-level boss still made Chang Licheng a little uncomfortable. He shrank his neck and said:
"That's right, that person hasn't contacted me for a long time. Unexpectedly, he suddenly chatted with me about last night.
In fact, I didn't pay much attention to it at first, but when he said he wanted to spend money to buy gel bait, I felt a little weird.
Yanjing is located in the north, so cockroaches are relatively rare, let alone the American cockroach, which is mainly distributed in the south.
And to talk about close relationships, there are at least five people in our major who are more familiar with him. For example, Wang Siyuan in the next class is from his hometown, so he shouldn’t contact me no matter what...
So the more I thought about this matter, the more something was wrong, so I went to Xu Shen..."
"You did the right thing."
After he finished explaining the causes and consequences, 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 recently went to Yanjing and couldn't see any cockroaches around him, so he used a fixed template in his expression, which finally exposed the truth.
After all, according to what you said, Wang Zhaomin was just an ordinary advertising student from a foreign school before, and he might not be so rigorous in what he said.
Of course, it cannot be ruled out that the other party did see some American cockroaches. Although American cockroaches are rare in the north, they are 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 Cyberspace Administration of China to take a look? First, determine the location of the other party?"
Tian Liangwei smiled and tapped him with his index finger, looking very happy:
"Xiao Xu, we want to go together."
As one of the most popular schools in China, the University of Science and Technology of China is often criticized by people with ulterior motives in public opinion. The number of confrontations that have occurred or are currently occurring in the field of network security is often countless times greater than in public opinion.
Therefore, although the computer science of HKUST started relatively slowly, it was very late that it was separated from the School of Letters and became an independent school of computer science.
But at present, when it comes to network security capabilities, with the exception of four local institutes, including Shanghai Jiao Tong University, Zhejiang University, Beijing University of Posts and Telecommunications, and Shuimu University, almost no one can say that it is better than HKUST.
As the leader in network security at HKUST, Wang Qingchen’s resume and abilities are naturally extraordinary.
Like Zhang Rui before him, he graduated from the mysterious Zhangshuo University Krypton Finance College.
He once served as the deputy director of the Institute of Information Technology, Chinese Academy of Sciences, and was one of the first batch of top experts in network security in China.
In addition, Wang Qingchen was once one of the seven legendary leaders of the Red League. He fought side by side with Lion and Bing'er many times and was the real main force in the battle in 2001.
Later, the Red League was disbanded for some reason. Wang Qingchen was hired by HKUST as the director of the Cyber Security Department at the end of 2013, and began to escort the growth of the next generation.
After receiving Xu Yun's notice, Wang Qingchen quickly rushed to the scene.
The head of the network security department at the University of Science and Technology of China looks to be in his early forties, about 175, with a relatively thin body and unusually thick hair.
After arriving at the office, Wang Qingchen first greeted Xu Yun and Xu Yun familiarly:
"Academician Tian, Dr. Xu, long time no see."
Xu Yun and Tian Liangwei nodded to Wang Qingchen one after another, 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 easy to query the IP. As long as the other party is not a top hacker, it won't be a big problem even if you use a CDN. As for personal information...
Dr. Xu, you may need to apply for official network access. After all, we can't do anything illegal.
Of course, if our University of Science and Technology really wants to investigate, the procedures will be relatively less cumbersome."
When Tian Liangwei heard this, he couldn't help but look at Xu Yun, their expressions a little strange:
The truth is this, but the words "obey the law" come from the mouth of this old black man who participated in the battle in 2001. Why does it feel weird?
It's like a well-known pigeon suddenly and righteously saying that everyone needs to make tens of thousands per day, which is contrary to the expectations of readers...
Tian Liangwei then forced himself to dispel the sense of disobedience and asked:
"Since it's such a personal information matter, let's not worry about it for now. Director Wang, can you lock his IP first?"
Wang Qingchen smiled shyly, without any hint of the arrogance of the previous Hongke:
"For small things, if there is only one QQ number, it may be troublesome to check, and it is not that 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 other party has passed CDN acceleration, the second-level domain name method and nslookup method are theoretically enough.
After all, according to what you said, the other party is most likely a dilettante who has just been recruited, and now he probably doesn’t even realize that he has been exposed.”
Seeing Wang Qingchen's understatement, Xu Yun and Tian Liangwei, two computer novices who couldn't even tell the difference between graphics cards, were immediately relieved.
Then Wang Qingchen opened the notebook he brought and let Chang Licheng board the Penguin.
"Applied Physics 2 Class Group...HKUST 21st Freshman Exchange Group...Jiaran, I like you so much...A gathering place for veteran drivers in Qiu Mingshan...**Fellow Club..."
After publicly executing Chang Licheng's penguin group, Wang Qingchen finally opened the previous chat history and started tinkering.
Half an hour later.
Wang Qingchen clasped his hands together and made a gesture like an earth-exploding star:
"OK, it's done. The IP address opposite is 202.106.xxxxxx... This is a residential broadband, near Dahongmen on the South Fourth Ring Road of Yanjing."
Xu Yun touched 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, after locking the other party's IP address, as long as he learns about the other party's recent movements or capital transactions through channels, he can probably be sure of the matter.
However, what surprised him was that Wang Qingchen shook his head:
"no need."
Xu Yun blinked, not knowing why:
"...Huh? Why?"
Wang Qingchen pointed at the screen with an expression on his face: "You wouldn't think it took me half an hour to lock an IP address."
"That's it, I paid special attention to the relevant information of this location, and finally found...
The Internet portraits of residents in the area are highly overlapping with a certain enterprise, including not only the nodes that are disconnected from the Internet every day, but also the wifi linked to Penguin during working hours, etc.
At the same time, the factory of that company is also very close to this area, so we can roughly judge that it is a dormitory building of a company."
"What company?"
"Let's take a look... Well, it's a foreign company. Its full name is Morishita Co., Ltd., and its Chinese name is Morishita Pharmaceutical. It mainly produces and processes pesticides and related derivatives."
