The Office of the Director of the Cyber Security Bureau of S City.

At this time, the office door was open, and the people inside were sitting at their desks, reading the materials carefully.

"Ju Chen, are you looking for me?"

Wang Le walked into the office and walked straight to the director's desk, picked up the cigarette on the desk and took one in his mouth.

"You boy, go and close the door. I don't want someone from the Anti-Smoking Committee to come in with a camera in a moment. ”

Director Chen scolded with a smile and put the materials in his hand on the table.

"I heard that your kid got Luo Bin back last night?"

Wang Le smiled.

"The director is still so well-informed, yesterday afternoon I saw Wu Mazi gambling in the forum, and I was ready to bring Wu Mazi back, but when I entered the door, I found that it was Luo Bin who opened the door for us. Coincidence or not, you say?"

Director Chen nodded, stood up from his chair and looked at Wang Ledao, "How is it?

"Take it, I cheated him yesterday. He now thinks that Liu Weijuan betrayed him and said everything. Wang Le said.

"Oh, what did he say about Kelly in MD Country, why did Kelly provide him with such a large amount of money every month, which didn't match his account in Crystal Entertainment.city. ”

Wang Le smiled and replied, "You may not believe it when you say it. Kelly wants to return to China, and all this money is laundered through him. According to him, Kelly bought a new identity in MD Country and wants to come back as a returned overseas Chinese. ”

Director Chen nodded with satisfaction.

"Good job, you keep an eye on this matter, catching Kelly back is our top priority, now you can go back and rest." ”

"Yes!"

Lying on the bed at home, Wang Le's mind was still combing Luo Bin's confession.

According to Luo Bin's confession, he met Kelly through Liu Laoer, and after getting to know Kelly, he only knew that Kelly was the gambling industry oligarch in MD country, and he didn't know anything about Kelly's other information.

Wang Le feels that there is something wrong with this confession, Kelly's identity is known to everyone, she is the behind-the-scenes boss of all casinos in MD country, and she is also the bookmaker of many online gambling websites.

Why would a woman with such deep capital want to cooperate with Luo Bin?

Another point Wang Le didn't understand, why did Luo Bin, a perennial person who sold citizens' privacy, suddenly stop working on online gambling websites? Who is behind this?

Wang Le felt that Luo Bin didn't tell the truth to himself, or that Luo Bin still had reservations in the face of himself.

According to Luo Bin's current situation, he may be sentenced to ten years in court, what is the reason why Luo Bin is willing to endure a ten-year sentence without betraying the people behind the scenes?

……

Not long after he fell asleep, Wang Le was woken up by a rapid telephone ringing.

"Hello?"

"Good...... I know...... Coming soon. ”

Wang Le glanced at his mobile phone, it was already half past two in the afternoon, Wang Le hurriedly got dressed, took the car keys and rushed out.

When he arrived at the door of the conference room in the bureau, Wang Le straightened his collar and pushed the door in.

"I'm sorry, I slept at home all night last night......"

Director Chen sat at the end of the conference table, waved his hand at Wang Le, and motioned for Wang Le to find a place to sit down.

"This is Mr. Zhao of Guangxin Company, and they have a case that you need to listen to. ”

As soon as Wang Le sat down, he listened to Director Chen's introduction.

Wang Le quickly stood up and said hello to the other party, and the other party also smiled.

Guangxin is a large company, with 40% of the country's broadband subscribers, and is also one of the largest network operators in China. This kind of enterprise rarely takes the initiative to report the crime, and their big business generally does not care about the slightest loss.

Seeing that Wang Le had already arrived, the people on the Guangxin side spoke: "In March this year, the security department of our Guangxin Group discovered that someone took advantage of the vulnerability of our DNS server to illegally hijack user traffic to a certain website. Everyone, please look at the screen......"

With the continuous introduction of the people of Guangxin Company, Wang Le has figured out the relationship.

As one of the largest network operators in China, there is a code vulnerability in Guangxin's DNS server that has been obtained by criminals. These people exploited this vulnerability to redirect a visit that would otherwise point to website A to website B.

At first, Guangxin didn't care, but as more and more companies came to complain, and finally after a local government website was forced to jump to a sex website by criminals, Guangxin finally couldn't resist the pressure and came to seek help from the Cyber Security Bureau.

After listening to the introduction of Guangxin Company, Director Chen spoke: "Wang Le, tell me your opinion. ”

Wang Le stood up straight and asked, "Has your company's DNS server vulnerability been fixed?"

Mr. Zhao of Guangxin Company shook his head slightly when he heard this.

"I see, I want to know how big the number of netizens affected is now?"

"More than 30 million people, but we've located the vulnerability and will fix it in the near future. ”

Wang Le nodded, and said again: "Are the technicians from your company's security department here today?"

As soon as he finished speaking, a young man stood up and introduced himself to Wang Le: "I am Yang Guang from the Guangxin Security Department, and this loophole was also the first to be found out. ”

"Hello, can you explain how the vulnerability works?"

……

In the continuous question and answer, the time has quietly advanced to 5:40 p.m.

Finally, after Wang Le learned all the details of the whole incident, Guangxin's reporting team walked out of the conference room.

Director Chen is older, and he is a veteran criminal investigator. There is no problem with arresting and interrogating people, but as for how these new types of cases are committed, Director Chen himself is also the first two big.

"How's it going?"

Director Chen lit a cigarette himself and threw one over to Wang Le.

Wang Le took the cigarette, picked up the lighter from Director Chen and lit it before he spoke.

"I've figured it out, I think there may be a ghost in the company. ”

"There's an inner ghost?"

Obviously, Director Chen was skeptical of Wang Le's answer.

"As far as I know, this server vulnerability in Guangxin is a very regular vulnerability, and any company engaged in network services providing DNS resolution will check for the existence of such a vulnerability. But ......"

"I understand, starting tomorrow, your second team will start following up on this case. After all, Guangxin is a giant enterprise, and we still have to take care of what we should take care of, understand?"

Director Chen interrupted Wang Le's analysis and said to Wang Le.

Wang Le nodded and said, "Okay, I'll take the people on the team to Guangxin tomorrow to see what's going on." ”

……

At nine o'clock in the morning, Wang Le rushed to the office building of Guangxin Company with the police of the second brigade. After verifying the police certificate and the letter of introduction, Wang Le directly found Yang Guang, who introduced him to the relevant information about the vulnerability yesterday.

"We want to go to the computer room today to see if there are any clues worth collecting. Wang Le said straight to the point after seeing Yang Guang.

Yang Guang nodded, taking advantage of the situation to put down the work at hand. got up and walked towards the computer room with Wang Le and the others.

"It's this server, it's our DNS resolution server. ”

Yang Guang pointed to a server in the cabinet and introduced it to Wang Le.

Wang Le whispered a few words to the policeman beside him, only to see the policeman open the black suitcase in his hand and take out a piece of equipment from it.

Wang Le looked at Yang Guang and asked, "We're going to make a data backup, okay?"

Yang Guang's face was a little bitter, and he seemed reluctant.

"This ...... I need to report back to my boss. ”

Wang Le didn't say anything, just took out a piece of paper covered with a red stamp from the document bag in his hand and handed it to Yang Guang.

"This is a notice to collect evidence, report this piece to your leader. ”

Yang Guang took the notice of evidence collection and nodded lightly.

"Wait a minute, I'll go ask the leader for instructions. With that, he turned around and walked out quickly.

After waiting for about five minutes, I saw Mr. Zhao, who had only met Guangxin yesterday, followed Yang Guang into the computer room.

As soon as he entered the door, Mr. Zhao said to Wang Le cordially: "Trouble Captain Wang to help us investigate the case in his busy schedule, don't leave at noon, and have a light meal in our company's canteen." ”

"Okay, we'll see how the work progresses in a moment. If it's convenient, then we'll bother Mr. Zhao. ”

Wang Le smiled and did not refuse.

The police on the side had already connected the instrument to the server with great discernment, looked at the progress bar of the instrument, and then said to Wang Le: "Wang Da, two and a half hours." ”

Wang Le nodded, then turned his head to Mr. Zhao and said, "It's my first time coming to our Guangxin building, can I go around?"

"It's our honor to let Captain Wang visit us. Come, I'll take you around the various departments......"

……

Three hours later, Wang Le sat in the car, looked at the front and said, "Is there anything abnormal in the server?"

"There are a total of four operation accounts on the server, and the logs of three of them are normal, and the operation logs of only one account have been emptied. The policeman sitting in the back seat of the car hurriedly replied.

"Has this person's identity been confirmed?"

"Yes, it's an outsourced technician. I'll check it out again when I get back to the bureau later. ”

Wang Le nodded.

"What else?"

"Uh...... There is another circumstance, I don't know if it has anything to do with it......"

"Say!"

"After you and Mr. Zhao went out, that Yang Guang's reaction was very abnormal, he always wanted to see what I did on the device, and he felt very nervous. ”

"Anything else?"

"Hmm...... The outsourced technician worked under Yang Guang. ”

Wang Le put away his serious gaze and turned his head to look at the policeman sitting in the back row, as if he was thinking about something.

After a while, he replied lightly: "I know." ”

After speaking, he turned his head again and said, "Xiao Zhao, your secondment to the Provincial Department has been approved by the Affairs Bureau." When this is done, you should report to the provincial office. ”

When the policemen in the back row heard Wang Le's words, they were immediately surprised: "Really, thank you Wang Da for cultivating!"

"Go to the provincial hall, don't embarrass the second team!"

"Don't worry, Wang Da, you will definitely not be embarrassed by the second team!"

"Alright, leave me at the intersection in a moment and you can go back. If Chen Ju asks me, he will say that I drank alcohol in Guangxin at noon, and it will not affect me well when I go to the unit in the afternoon, do you know?"

"But Wang Da, you didn't drink......"

Wang Le raised his hand to stop Xiao Zhao from continuing.

"I said drink it!"
