The sea and the book [criminal investigation]

Chapter 48 Liu Yuanchun

Lu Nanchu came back in the heavy rain, but was unable to open the door downstairs of the unit because of a power outage.

Shi Yuning chatted with another person in a private message on a social network, and then checked their chat history from yesterday.

It's all his fault that he has a crush on a straight steel man who doesn't understand his style, so he doesn't have any hope for the straight steel man.

Two days ago, through Sunny's recommendation, he added the contact information of a person who was noted as Lawyer Wu.

This Lawyer Wu is a wonderful person. He is a lawyer of Linning Juncheng Law Firm, but from his social space, it is completely impossible to tell that this person is a lawyer. They are all three-paragraph poems full of literary flavor.Shi Yuning only wished he hadn't known Lawyer Wu when he was a screenwriter, otherwise just looking at Lawyer Wu's spatial dynamics would inspire inspiration like a faucet.

According to Sunny, Attorney Wu was originally a legal consultant who provided legal assistance to Bai Jinse. He is knowledgeable and a gold medal lawyer of Juncheng Law Firm.

The story that Shi Yuning told Lu Nanchu on the phone about the murder of his lover was learned from Lawyer Wu.

Lawyer Wu once had a lover who was killed many years ago.

Because the culprit was a child under the age of fourteen, and the criminal channel was only carried out through the Internet; so his lover died, and no one was responsible for his death. Leaving provocative messages on the lover's social account.

What kind of child is this!This is simply the little piranha devil.

When Shi Yuning heard this story, he was very angry. He put himself in his shoes and thought that if this kind of thing happened to him, he would never be as calm as Lawyer Wu.

And if Lu Nanchu died...

He shook his head hastily, pushing the terrifying thought out of his mind.

Who doesn't know that Captain Lu used to be a member of the SWAT team, and he was a good old man who could fight and handle extremely well. A person like him would have to live for at least a hundred years.

Just as he was thinking wildly, there was a knock on the door.

It's still raining outside, and the community is still out of power, who will come here at this time.

Shi Yuning glanced behind the cat's eye first, and found that it was Lu Nanchu who came, thinking he had misread it, so he hurriedly opened the door: "Brother Nan, why did you come back suddenly?"

"Are you okay?" Lu Nanchu asked him, looking at him.

"What can I do! Even if there is thunder, it won't hit me." Shi Yuning stood up with his head held high, and after closing the door, he and Lu Nanchu walked to the sofa and sat down, pouring tea for him, "Captain Lu came over in the heavy rain , It should be for official business, right? But I have always obeyed the law, so I shouldn’t be on the wanted list of the Public Security Bureau, right?”

Lu Nanchu took the tea he handed over, put it on the table in front of him, took out his mobile phone, clicked on the recording interface, and put it next to the teacup.

Shi Yuning still smiled lightly in front of him: "It seems that Captain Lu is indeed here for business. If you have any questions, just ask!"

"Every question I ask, you have to think clearly before answering. If you don't think clearly, keep silent." Lu Nanchu deliberately ordered before turning on the recording button, "It has been 26 hours since Bai Jinse had a car accident on Dongjiang West Road. Yes. Do you remember the last time you saw Bai Jinse?"

"It was when I hadn't resigned from Yunqi. I went to see Director Luo and told him about my plan to resign, and I happened to meet Teacher Bai." Shi Yuning recalled seriously and elaborated, "At that time, Teacher Bai didn't say anything. I said hello and left. The last time I talked to Teacher Bai was half a month ago. She heard that Yuan Yuan was sick and called to ask..." Yu Ning got stuck at this point; Why didn't he think at that time why Bai Jinse knew Lu Yuanyuan?Now he accidentally slipped it in front of Lu Nanchu.

Sure enough, Lu Nanchu showed a puzzled expression: "What's wrong with Yuan Yuan? She and Bai Jinse knew each other?"

Shi Yuning still had a guilty conscience and said: "I heard that Mr. Bai has been to Yunda to give a speech, so he may know Yuan Yuan."

Lu Nanchu didn't dwell on this issue anymore, so he took out the recorder and played a recording for him, which was the recording of her last phone call in Bai Jinse's cloud backup.

"Do you know the person talking to Bai Jinse in this recording?" Lu Nanchu asked.

Although Shi Yuning had only met Sunny once, Sunny's voice was very recognizable, and he recognized that the person Bai Jinse was talking to was Sunny the moment she spoke.

What surprised him the most was that Bai Jinse and Sunny mentioned lawyer Wu during the conversation; this lawyer Wu was obviously Wu Shengqiao, the ace lawyer of Juncheng Law Firm that Sunny recommended his business card to.

Bai Jinse has a deal with lawyer Wu.That is to say, lawyer Wu helped Bai Jinse provide legal aid, and Bai Jinse followed the clues to find evidence and sent lawyer Wu's enemy to the police.

Now that Bai Jinse was killed, Lawyer Wu had no choice but to seek help from another, and it happened that Sunny hit it off. "In this recording, when talking with Teacher Bai, the voice is a bit sunny. "Shi Yuning used uncertain words, and first distanced himself from the relationship, "But I'm not completely sure."

Lu Nanchu nodded; he also guessed this possibility at first.

He asked again: "Then tell me, do you think Bai Jinse's murder has something to do with your teacher Cheng Qiyan? You can make bold guesses, and we will find out the truth."

"If you listen to the recording just now, I think it's possible. Teacher Bai doesn't have any enemies, unless...someone wants to kill people to silence them." Shi Yuning thought about it before saying, killing people to silence him This is also the most acceptable answer so far; he thought about it and asked again, "Officer Lu, do you know who this Lawyer Wu is?"

Lu Nanchu looked up at him and asked, "Do you know Lawyer Wu?"

Shi Yuning was stunned for a moment before bowing his head: "I probably haven't seen it before."

He only had one chat record with Lawyer Wu, and the rest of the stories about Lawyer Wu came from watching the dynamics of the space and Sunny's narration. In the story, Lawyer Wu was a particularly miserable and pitiful person.

It is human nature to sympathize with the weak, because Shi Yuning's previous job as a screenwriter made it easier for him to have psychological empathy for other people's misfortunes.

But there are too many poor people in the world, and anyone can tell what misfortune they have encountered in order to win some sympathy.

Lu Nanchu was still about to say something, but the phone that was recording on the table rang suddenly; he ended the recording, went outside to the corridor window and connected the phone.

This call was made by Guo Chen. He said that the Luoxing Internet police had received new information that the social network server seemed to be malfunctioning.

After finishing the call, Lu Nanchu entered the room and told Shi Yuning that he was about to go back in a hurry.

The rain outside seemed to be getting heavier, and Shi Yuning lamented that Captain Lu really had a work attitude regardless of the weather.

And he is like a script-killing NPC with a script in his hand. What to say and what to say are all regulated in the frame, which is in line with the maximization of profit results; as an NPC, he has to cooperate with players and werewolves in everything. action.

But Sunny said that everything is about to close the net.

Standing in front of the window and seeing that Lu Nanchu had left downstairs, Shi Yuning went back to the computer and sat down, continued typing on the keyboard to browse comments, and continued to write this big play.

When Lu Nanchu returned to the Municipal Bureau, he received the new file from Luoxing Internet Police, as well as the program chain decoded by Song Shi.

In the past month, the maintenance system of the social network has repeatedly claimed to have been attacked by hackers, and the program code of the system has been modified.

However, some time ago, when the Luoxing Internet police were dispatched for network security, some netizens called the police and suspected that their social account had been stolen. However, he checked his social account login information, but found no IP information for logging in from another place.

He firmly believed that his account must have been hacked, because he found that he liked things that he had never viewed, and even published tirade without any memory on topics that he had no memory of.

I thought it was just an ordinary hacking incident, but I didn't expect it to lead to more things.

After the official self-examination of the social network, it was announced that the server had failed, causing the user's account to extract the content of other user accounts; at the same time, it expressed its apology to the user and was willing to compensate the user to a certain extent.

Netizens were amazed that the official social network of Toutie would admit his mistake so readily, which is simply unbelievable.

Less than half a day after the release of the announcement, the Luoxing Internet police discovered a major loophole in the background of the social network system. At least ten years ago, the server of the social network was hacked into a sieve by hackers; A crawler code has long been embedded by hackers, and the personal information of all netizens using social networks has no privacy in front of hackers. They can even switch to the background of any netizen's account at will, and use their identity information to publish any information.

In the era of big data, ordinary netizens really do not have any privacy at all.

But the programmers of the social network have replaced and repaired the server countless times over the years, but they have not discovered this loophole at all, so this black wind has been blown by the social network as a medium for so many years, and all netizens have become in the hands of hackers. Fiddling with resources and data.

The security loophole of the social network discovered this time is more serious than any previous network security incident.

Almost on the day when the incident was revealed, the stock price of the holding company behind the website went crazy, and stockholders scolded them fiercely in various forums.

In the hacking incident, it seems that the social network is also the victim on the surface; but as a major network site, it cannot guarantee the user's information security, and even allows this vulnerability to exist for many years without being discovered. Information to perfunctory the public, this is simply a big outrageous incident.

Netizens cursed and said they would boycott social networks to maintain network data security.

In the hacking incident, the professional acumen of the police made them inevitably have other suspicions and associations with the case.
