Evidence hunting forensic 4 unsolved case code

For us?

Suspicion filled his mind again, and Lin Dong suddenly felt he couldn't breathe. The feeling of suffocation from receiving the warning from the "poisonous bee" held him tightly again.

At this time, Luo Jianan made a gesture, motioning him to come out of the room to speak.Standing still in the safe passage, Luo Jianan handed him a cigarette, weighed it a bit and reminded: "If the Hou Department mediates and reports this matter, your unsolved case team will be in danger."

After several days of rainy weather, the shredded tobacco was damp and made an annoying crackling sound when burning.As the smoke floated over his drooping eyelashes, Lin Dong sighed, "Whoever should come will definitely come, and what should be hidden cannot be avoided."

"Hey, there is a wrong and a debt, who set you up, we can't find it out forever?"

"Can you trace the source of the virus?"

"..."

Luo Jianan was dumb, hooked his hands and scratched his eyebrows, and smiled embarrassingly.In fact, Lin Dong had no intention of ranting against him, and he was kindly reminded, but some things really can't be solved with lip service.According to his previous experience in network security, if he pursues him, he will only find layers of agents, and they must be outside the country. After a few years of hard work, he may not be able to get the real IP address of the attacker.

However, Luo Jianan's "trick" reminded him - since the other party can set them up, they can also treat them in their own way.

After sorting out his thoughts, Lin Dong demanded, "Call Deputy Director Sheng and ask her to come down and chat alone."

Luo Jianan's expression suddenly became a little twisted: "Do you still think that few people know about this?"

"Luo Jianan, if I want a mobile phone, I'll call it myself." Lin Dong was secretly lucky, thinking that I can't control you, what's the matter?

"Okay, I'll call, anyway, it's not me who was sent back to the second basement floor after something happened."

Silently typed the manuscript, Luo Jianan dialed the landline in Sheng Guilan's office: "Hey, Deputy Director Sheng, I, Luo Jianan... Ah yes, please, come to the safe passage on the sixth floor... It's not me looking for you, it's Team Lin ...Ah? He...he is charging his mobile phone, I just passed by... OK, OK, we will wait for you..."

After hanging up the phone, he breathed a sigh of relief and said to Lin Dong: "Every time I call Sheng Guilan, I have to do some mental training. That aunt's mouth doesn't use dirty words when swearing, but she still scolds me and buckles me when I do." My salary!"

——You deserve to be scolded, you just need to open your mouth.

If it weren't for something pressing in his heart, Lin Dong would really have been entertained.

After a while, the sound of opening and closing the door came from upstairs, followed by the imposing "thumping" sound of high-heeled shoes.Standing in front of them, Sheng Guilan sized them up, and then unexpectedly, she reached out and asked Luo Jianan for cigarettes.

"You smoke, too?" Luo Jianan asked cautiously while passing the cigarette.He knew that some policewomen in the bureau smoked, but he had never seen Sheng Guilan light a cigarette in front of others.

"When I was working under your grandfather, Fade Chen rubbed me to smoke every day." Sheng Guilan exhaled the cigarette skillfully, and turned to look at Lin Dong with a dignified expression. Put shit on his face."

As soon as these words came out, Luo Jianan immediately gave Lin Dongyi a "what did I say" look.But Lin Dong was not afraid of Sheng Guilan's dismounting, and calmly informed the current situation.The more Sheng Guilan listened, the more incredulous her expression became. She raised her hand after hearing this, signaling Lin Dong to give her some time to digest the ins and outs.

The three of them were staring at each other, Tang Zhexue knocked on the door and came in, giving Lin Dong a mobile phone.Seeing that Sheng Guilan was also there, with a cigarette in his hand, he was slightly astonished for a moment.Knowing that Lin Dong had already informed the leader of the unexpected situation, he weighed his words and said cautiously: "Hou Chu said that this matter needs to be communicated to the Fang Bureau. As for the internal mediation...it still depends on the director's opinion."

"Old Fang won't make trouble for himself if he's full."

Sheng Guilan gave them reassurance, then crushed the cigarette butts with her bare hands under the astonished gaze of the juniors, and threw them into the trash can.This tough guy's demeanor reminded Luo Jianan of what he heard from Chen Fei about Sheng Guilan's time in the Serious Crime Squad: when she acquiesced in beating up suspects in the early years, Sheng Guilan, as the only policewoman on the team, was the most ruthless Even murderers with big arms and round waists can be cured by her crying father and mother; appearing on the scene, three or nine days old, this aunt can also go down the reservoir, and dig out the septic tank. If you don't pull the rope, go down; when chasing the suspect, she is as light as a swallow, Chen Fei and Zhao Pingsheng are about to vomit after chasing her, and she still runs forward like a rabbit.

Everyone in the bureau said that the woman who had been involved in a serious case was the ancestor.

This ancestor is not a person who likes to go around in circles, and said bluntly: "Lin Dong, just tell me what you want now."

"The old case is brought up again. Now that the Sunflower case has been solved, we can disclose the information of the persons involved." Lin Dong calmly put forward his own thoughts, "According to our judgment, the suspect used the 'stamp' to obtain information about the Sunflower case from Chen Jun. In other words, she wanted to solve the case by herself, but Chen Jun's accidental death hindered her progress. We already know that the suspect obtained the progress of the investigation through a mobile phone virus, so the suspect must know the case now It has been broken, but this honor belongs to the police, not hers, and public announcements, praising the achievements of the police with great fanfare, may anger the suspect."

"Put gold on your face?" Sheng Guilan smiled, but her tone was not kind, "Lin Dong, I know you have a quick mind, but don't forget that all the people involved in the Sunflower case are dead, and they are still dead. During the investigation, tell me, how do you write this notice? Don’t turn around and slap yourself in the face if you didn’t get the money posted!”

Sheng Guilan's words made sense, Tang Zhexue and Luo Jianan both turned their eyes to Lin Dong when they heard it, and saw the corner of the other party's mouth hooked up, and said with confidence: "Ask Qiu Ying to write and give her the exclusive right to report. I have read the article written by her. , to be honest, her pen can make or destroy a person."

Sheng Guilan sneered: "Since you already know what kind of person she is, aren't you afraid that she will ruin you?"

"I'm already like this, what else can I ruin?" Lin Dong asked with a smile.

"Don't laugh so badly, it's useless to trick a handsome guy like me."

"Hey! Deputy Director Sheng! You swear words!" Luo Jianan was caught. Last time, Sheng Guilan fined him [-] yuan for swearing, and his heart hurts.

Sheng Guilan immediately frowned: "Get out! You were still liquid when the old lady scolded you!"

"—"

Luo Jianan was stunned.

At night, nearly half of the windows on the wall facing the street of the City Bureau Building still had lights.The whole building was much quieter than during the day. Compared to other floors where people were walking and talking, the corridor on the sixth floor only had the occasional sound of mechanical keyboard knocking.

Every hacker has his own unique "signature", and Yang Kelin tries to use this characteristic to track each other.However, it is clear that this hacker does not have the habit of sharing his experience on relevant forums. He has searched several major hacker gathering places and technology groups on the Internet, but so far has not gained anything.Of course, some hackers do not have a life plan to emerge in the circle, and engaging in technology is just a hobby.As the so-called masters are among the people, it is possible that a seemingly insignificant person can dominate the Internet in private.In the cases he dealt with when he was working in the network security of the provincial department, the suspects went down to the general corner to the elderly, and there were always surprising discoveries.Creation comes from life, so it can be seen that Mr. Jin Yong's "sweeping monk" was not compiled based on imagination.

There was a burst of chattering sound from the camp bed behind. It was Ou Jian, who couldn't bear it anymore and fell asleep, dreaming of something delicious.

Ding!The phone screen lit up, Yang Kelin picked it up and took a look, then put it down with a frown, and turned the phone to silent mode.Rong Sen sent it, asking when he would go home.However, there was no answer, and he didn't know when he would go back.The blank relationship experience made him unable to face the other party honestly. Once they met, he was afraid that he would uncontrollably ask "Do you like Wen Yingjie?", and lose the illusion that he shouldn't have had after getting the answer.

After a while, the phone screen lit up again. This time Rong Sen didn't send a message, but made a call.The beating over and over again forced him to pick it up, but he didn't know what to say when he picked it up, so he could only respond in silence.

There was also a silence over there, and it took a while before Rong Sen complained: "You haven't come home for more than a month, and the house is full of dust. I spent a whole day cleaning your room today. It's starting to hang cobwebs, you know? Are you really that busy?"

"...Ah, I'm still working overtime..."

Yang Kelin is also telling the truth.But hearing Rong Sen say that he helped him clean the room, he was somewhat happy.In the past, when he was busy and couldn't go home, Rong Sen would help him deliver a change of clothes and clean the room. I didn't expect that after such a long cold war, he would still think about helping him clean the house.

However, I was happy for only five seconds, and then I heard the other party say coldly: "Then don't live in my place, the rental contract doesn't let you use my place as a warehouse."

"I... haven't found a suitable house yet..."

"Did you really find it?"

"found……"

There was another silence in the receiver, and then hung up with a "click".Putting down the mobile phone close to his ear, Yang Kelin wiped his face wearily, and leaned back on the back of the seat.Sometimes he can't help thinking, why do people have emotional needs?So tired, you may not be rewarded for your efforts, but you still have no hesitation, going all the way to the dark.

"Did you argue with your girlfriend?"

Yang Kelin was startled by the sudden inquiry from behind, and quickly turned around to stare at Ou Jian.Ou Jian was lying on the camp bed, looking at him innocently: "I'm a light sleeper, and I wake up when you talk."

Pressing his chest where his heart was pounding, Yang Kelin turned around, leaving him with the back of his head.People are scary, scary to death, he doesn't want to talk to Ou Jian at all now.Besides, he doesn't have a girlfriend, so where's the fight?

It's not that Ou Jian didn't have any good eyesight. Seeing that Yang Kelin ignored him, he felt a little bored, turned over, and continued to sleep facing the wall.After waking up and going back to sleep, he couldn't fall back asleep. He rubbed against the camp bed for a while, but still couldn't help it: "Yangzi Yangzi, tell me about your girlfriend."

It wasn't that he was gossiping, but that Yang Kelin was too silent. His partner had tried his best to find topics these days, but no matter what they were talking about, the other party could end the battle within three sentences.If he didn't know that the other party has such a boring character, he would really feel that he was rejected.

I heard Yang Kelin say angrily: "I don't have a girlfriend."

In view of what he had heard and seen since work, Ou Jian pondered for a few seconds and asked tentatively, "Then...boyfriend?"

"No!" Yang Kelin had the urge to hit him with the keyboard.

"You murdered me." Ou Jian was wronged for a second, thinking of Yue Lin who was sick at home, and sincerely said: "It's better for Mumu, Mumu never murdered me."

"Whoever is good, whoever you go to!"

Yang Kelin has blue veins popping out of his forehead.Originally, Lin Dong arranged Ou Jian as his partner, but he was not very happy. This kid can code, but compared with him, he is almost at the kindergarten level.He talked too much, he poked to the side and kept chattering, so much so that he even knew the network IP address of the other party's home.

—Wait a minute, home IP address?

A thought suddenly flashed in his mind, he turned on his phone and connected to the computer at home.The network card of that computer supports the wake-on-lan function, so that people can use it anytime outside.

Seeing him suddenly concentrating on the phone, Ou Jian turned over and got up, secretly rubbing it on his back: "What are you doing?"

Frowning slightly under the pressure, Yang Kelin held back and explained patiently: "The virus returns, I use my computer to send attack commands, and the other party may access my host after being attacked, so there is a chance PING to the IP address."

Professionally, Yang Kelin can understand Ou Jian without explaining too much, but he still has doubts: "There are so many agents, can you PING?"

"I made a limit, and the proxy server does not receive it."

"Did you change the virus script?"

"Ah."

"... Awesome..."

Hanging on someone's back, Ou Jian was deeply impressed by watching the other party skillfully input a series of codes with the mobile phone.He understands the theory, but he almost doesn't understand it in practice.It seems that the knowledge that has been left behind must be picked up again and deepened. After all, this is the only skill that can make the elder brother look at him highly.

After making up his mind, he straightened up and asked sincerely, "Yangzi, let me take you as my teacher. From now on, we will make our debut as the city bureau white hat duo!"

Still white hat?Yang Kelin didn't even have time to roll his eyes at him.
