The sea and the book [criminal investigation]

At 8:30 pm on August [-], Yunying Communication University released an obituary.

According to the usual practice, after the death of a school teacher, Yunchuan will publish the obituary on the campus network to express condolences.

However, the obituary released by Yunchuan at [-] o'clock tonight attracted the attention of the police because of the large amount of information.

"Bai Jinse, a teacher specializing in new media in our college, was involved in a car accident on Dongjiang West Road at 15:40 today and unfortunately died.

Deeply mourn the passing of Teacher Bai!

However, Teacher Bai's car accident was not accidental but man-made. The murderer intentionally caused a car accident and killed Teacher Bai, and then fled. He is still missing.

Warn all teachers and students, pay attention to your own safety in recent days, cherish life and stay away from dangerous people.

I look forward to catching the real culprit as soon as possible, and may Teacher Bai rest in peace. "

It has been four hours since Bai Jinse died in a car accident. According to Yunchuan, Bai Jinse died in a car accident. The police are still investigating the details.The Yunying police haven't announced the details yet, but Yunchuan issued a public announcement saying that Bai Jinse was murdered, and it seems that he has already obtained conclusive evidence.

Only 5 minutes after Yunchuan released the obituary, several local authoritative media accounts such as Yunbao also released information on social software and official accounts, saying more convincingly than Yunchuan that a vicious murder occurred on Dongjiang West Road this afternoon. The deceased was a professional teacher of Yunchuan New Media, while the murderer abandoned the car and absconded, whereabouts are unknown.

Where did these people get their information from?

The effect of the mixed news is obvious, and it has caused a small panic in the comment area.

[Black Friday: What the hell is going on here?Another murder?It's too scary, right? ]

[Pray for peace: I'm already panicking.My friend was at the scene of the crime this afternoon, and I heard it was very scary. ]

[Lactobacillus yogurt: shivering, I really dare not go out. ]

······

The news continued to ferment for about 10 minutes, and Yunbao first retracted the message just now, and put a new announcement on the top saying that their account was stolen, and the previous message was not from the editorial department of Yunbao.

Following the rhythm of Yunbao, several social media later withdrew the original information, saying that they had been hacked, and in the end, even Yunchuan said that the obituary was done by the hacker, and re-released the obituary, stating the facts normally and expressing condolences .

Yunchuan quickly called the police, claiming that the school system was suspected of being hacked, and the administrators frequently logged out after logging in to the system, which may lead to the leakage of students' private information.

Since hackers can overcome Yunchuan's system and forge announcements, it will be easy for them to steal the personal information of Yunchuan students.

On the other hand, it is also to clarify that the first obituary was indeed issued after being attacked by hackers. Yunchuan was worried that if it did not clarify in time, it would be considered that Yunchuan deliberately spread rumors and affected the reputation of the school.

After receiving the report, the colleagues in charge of network supervision in the technical room felt that it was likely to be those "old acquaintances" again.

Sunny's actions this time are even more arrogant than before.

After investigation, Song Shi said that it was not the hacker's intrusion into the cloud transmission system at all, but the intrusion of the social network system.

Hackers use crawler tools to screen big data, and then embed a new code in the social network system, which can automatically grab big data information for information replacement.That is to say, no matter what the content originally edited by these media is, it will be automatically replaced with the content edited by hackers in advance at the moment the information is released, and the high technology is very smart.

And this smart program can really complete the process of "catching people along the network line".

The Yunchuan system freezes frequently, purely because the Yunchuan server is too spicy.

The reason why it is determined that this hacker attack was done by Sunny is because the embedded program and the program code left after Sunny attacked the social networking system last time and deleted information are completely from the same hand.

Sunny, like Jiang Anxu, is really everywhere.

Sunny has such a high-powered technology, but it is here to cause damage, which is very uncomfortable.

Bai Jinse's niece Bai Lihua got off the plane at two o'clock in the morning and rushed to the police station overnight.

She was still dressed as a student, and came in with her schoolbag on her back; when she saw the policeman, she began to cry, tears streaming down her big bright eyes, and she stood in the hall speechless.

Shu Manyue came to pick her up, and quickly wiped her tears with a tissue: "Are you Bai Lihua?"

She nodded, her voice choked up: "Yes, I'm Bai Lihua."

"I'm Shu Manyue from the Criminal Police Brigade. Come with me!" Shu Manyue took Bai Lihua to the lounge, then poured a glass of water for her, "Drink some water? You just came back from Luoxing, right? "

"Yes." She lowered her head while holding the glass of water, tears pouring out again.

Lu Nanchu asked Shu Manyue to pick up Bai Lihua because he also asked Shu Manyue to comfort her.

Bai Jinse was Bai Lihua's only relative, and she should have felt the most pain when she heard the news of Bai Jinse's death.

Bai Lihua and Shu Manyue are about the same age.Although she looks like a student, she is actually 24 years old and works as a primary school Chinese teacher in Luoxing.

"Comrade policeman, is my aunt really..." Bai Lihua asked with her red and swollen eyes.

"Yes, Bai Jinse passed away unfortunately in a car accident this afternoon." Shu Manyue tried her best to speak tactfully, and her tone slowed down a lot, "We notified you to come back to Yunying because of your aunt."

Bai Lihua wiped her tears with a tissue, sobbing in a low voice: "I want to see my aunt. I haven't seen my aunt for a long time."

Shu Manyue could only tell her that Bai Jinse's body was in the hospital tomorrow, and Qin Zheng and his forensic police sent the autopsy report over after the autopsy.

"This is Bai Jinse's autopsy report." Shu Manyue handed her the autopsy report, "Bai Jinse's car accident is still somewhat suspicious, so I hope you can assist the police in their investigation."

"Ah?" A bit of astonishment flashed across Bai Lihua's face, and she looked at Shu Manyue with tears in her eyes, "What do you mean? Didn't my aunt pass away in a car accident?"

She flew in the sky for several hours, and came to the police station as soon as she got off the plane. She didn't know about the oolong event of the obituary in the cloud tonight.

After Shu Manyue received the instruction, she told her the truth about Bai Jinse's murder and asked her to keep it a secret for the time being.

Bai Lihua didn't react for a while, so she hesitated and asked, "But why did this happen? My aunt has no money, no power, and no enmity with others, so how could she be murdered? Who is the murderer?"

Shu Manyue only said that the police are still investigating and arresting the escaped murderer.

"Thank you, Comrade Police, it would be great if we can catch the murderer." Bai Lihua whispered, sobbing.

After reassuring Bai Lihua, Shu Manyue went to the office. Yan Geng looked at the surveillance and said to her curiously: "This Bai Lihua looks like a middle school student, not a primary school teacher at all."

In fact, Bai Lihua cried so much just now, Shu Manyue coaxed her like a child.

"She is also quite pitiful. The only family member left just like that." Shu Manyue sighed helplessly.

Bai Lihua sat in the lounge for a while, and suddenly saw the phone in front of her light up, and there was a new unread message.

When she clicked on the unread message, her pupils suddenly dilated.

Remarks on the sending number of unread new messages is my aunt.

"Lihua, when you see this message, I should be gone.

I don't know when the accident will come, but I can know that someone is following me recently.

After you receive this message, immediately go back to Yunying, back home, I left something for you at home.

You get that calling card from the nightstand in your room, and remember to keep that calling card with you for the next 24 hours.During this period, someone will contact you, don't be afraid, she is my aunt's friend, and she will protect your safety. "

After reading this message, Bai Lihua only felt creepy.

My aunt has passed away, so this message should be released regularly!

But it's not right, my aunt was murdered, how did she know that something bad happened to her today, and then she just set up to send this message tonight.

After the aunt was killed, the police would definitely check the aunt's mobile phone information and communication records, but they obviously did not find the existence of this information.

Now my aunt's mobile phone and mobile phone card should be in the hands of the police, and no one should be able to get my aunt's mobile phone and pretend to be my aunt to send her this message.

So what the hell is going on here?

It was terrifying, like a pair of eyes behind her were staring at her all the time in the dark night.

After a while, Bai Lihua saw the policewoman coming over again, and asked anxiously, "Comrade policeman, is my aunt's mobile phone here? I, I want to see if my aunt might have left me a memo or a few words." .”

"I'm sorry about this, but I can't help you at the moment. Bai Jinse's cell phone was damaged in a car accident and cannot be restored; the records in the memo have also been found." Shu Manyue expressed regret.

Bai Lihua was not surprised to get this answer.

If the aunt's mobile phone has been damaged in a car accident, there are only two possibilities left.

Either the information is released regularly, or someone copied the aunt's mobile phone card to help the aunt send this message.

Bai Lihua's mind was very clear, and she quickly realized that she decided to go home first to see what her aunt had left for her.

My aunt was killed suddenly. Maybe she can find out what happened when she goes back.

After Shu Manyue left, Bai Lihua left the police station with the excuse of going to the bathroom.

It was about dawn, so she took a ride home on the side of the road, and when she got off at the destination, it was already full dawn, and it happened to be five o'clock in the morning when she checked her phone.

From yesterday when she heard the news of her aunt's death, and rushed back to Yunying overnight, until now, Bai Lihua has been tense, not daring to relax in the slightest, for fear of missing important news.

After entering the house, Bai Lihua returned to her room as instructed by the text message, and opened the bedside table.

There was indeed a phone card in the bedside table, as well as a letter that Bai Jinse had left for her.
