The door of the Information Security Department suddenly opened, and Fang Chang walked in with a gloomy face: "Has there been any progress?"

There have been few new developments in the results of outside searches, and traditional investigative methods have not had much effect on such a new type of crime.

“…… Sorry, the code of the victim's buckle and scarf has not been cracked. Duan Ze, who was mainly in charge of this part, shrunk his neck.

"Haven't cracked it yet, I think you've been working on it all morning!"

After all, Penguin is one of the best companies in the industry, and if it could be cracked so easily...... "I would have gone to work for an IT company a long time ago." Duan Ze silently added in his heart.

"Then you call the penguins and ask them to cooperate with the investigation and give us the password directly. Fang Chang said unhappily.

"I've already called, but it's more troublesome, and I have to get permission from the local police. I'm already applying. However, the penguin has already agreed to set additional permissions for our IP. Originally, if the password was incorrect three times, it would take at least a minute to re-enter the password, but now Penguin has removed this restriction for us. In other words, as long as it's us, no matter how many times we try different passwords......"

"You just have to sue me, how much time is needed. Fang Chang interrupted Duan Ze's tirade and said straightforwardly.

"If it's long, it's about two weeks, and if it's short, maybe it's the next second. After all, the deduction password can be as long as it is, and each character has 62 possibilities for counting numbers and letters, and a few digits of the password will have to calculate sixty-two squares, and if you add symbols, it will be more......"

"In other words, I won't be able to rely on you for a while?" Fang Chang narrowed his eyes.

Duan Ze felt like a frog being targeted by a snake, and he stubbornly said, "Yes...... Yes. ”

The door was opened again, and Fang Chang turned around and saw his partner Li Wanji walking in, and said with a smile: "I heard that they said that you came here in the Information Security Department, what's the matter, are you bullying children again?"

"How's your investigation going?"

"As you might expect, it's almost useless. But it's kind of a little bit clearer. To put it simply, the victim panda eats sweet potatoes, and his life relationship is very simple, and he hardly goes out on weekdays. His wife and he divorced two years ago, and the alimony was settled, so it is unlikely that he will kill for love. In addition, the editors of the magazine who have more contact with him are the editors of the magazine, but there is no contradiction in the middle, so there are not many clues in this regard. ”

Li Wanji continued: "Judging from his past speeches, he should usually watch anime or novels at home......"

"It's called an otaku, right?"

"Uh...... Probably. Anyway, the only speech he has recently made that contradicts people is the one about "Shangjing Ghoul......"

"I remember that scarf was indeed issued on the 4th, right? And the time of the victim's death was exactly the 5th. Fang Chang touched his chin thoughtfully.

"The vendetta is logically reasonable. Sure enough, it's the person he killed, right?" Li Wanji frowned and clasped his hands.

"Hmm...... My sixth sense tells me that he is not a murderer. ”

"This kind of thing can't be explained to the outside, now you can stare at this case on the Internet, don't you come nonsense!"

"When have I been here. Fang Chang squinted at him.

You've always been nonsense!" Li Wanji roared in his heart.

"Officer Fang, the password has been cracked!" Duan Ze, who sat back in front of the computer at some point, said excitedly.

Fang Chang and Li Wanji hurriedly walked over and gathered in front of the LCD screen.

Duan Ze clicked on the message record and quickly found the problematic message. Looking at these pieces of information, Fang Chang was thoughtful......

Li Wanji said: "Wait, look at this." "Moreover, in addition to plagiarism, you also have black material in my hands", this is obviously referring to the "Shangjing Ghoul" that was exposed for plagiarism! Sure enough, the murderer was the suspect we caught, and you actually said that he was not a criminal, and we were all deceived by him!"

Fang Chang showed a meaningful smile: "No, this passage proves that the criminal is not Li Er. ”

"Huh?

"The sentence 'In addition to plagiarism, you also have black material in my hands' is contextualized, and it is obvious that Deng is using the suspect's plagiarism to squeeze money. But "Shangjing Ghoul" plagiarized this long scarf, but it was exposed before this conversation, and the evidence that has been exposed, how can it be blackmailed?"

"I see. ”

"From this conversation, we can now know three things. First, the suspect is a literary and artistic worker, and his works are suspected of plagiarism. Second, Deng had found evidence on the plagiarism and sent it to the suspect. Third, the time of the crime should be after five o'clock. ”

"Since the perpetrator arrived at five o'clock, we can eliminate the suspect based on the surveillance video at the entrance of the hotel, right?"

"I don't think it's possible to find the killer there. Even I can think of a lot of ways not to be caught on surveillance footage. And judging from the meticulous process at the crime scene where there were no fingerprints or hair, would the murderer leave such obvious evidence?" Fang Chang nodded his temples: "Such a planned murder case will not let you solve it so easily." ”

"So what to do?"

"Evidence, just get the evidence. Fang Chang turned his head and said to Duan Ze, who was sitting in the chair, "Can you find the text he passed on to others recently?"

"It's more difficult, Yunwen Jiàn, the backup time is only one week. I also didn't find a backup on my computer, probably formatted. ”

"Formatting?"

"It's to restore the whole disk to an unused state, and I see that the D drive seems to have been checked once. Duan Ze opened a blank D drive, "But this kind of formatting doesn't really delete the text." Instead, the place where there was originally a text jiàn was marked as none. Only by putting a new text jiàn in it will the original text jiàn be replaced. If you use the number of jù recovery software, there is still a certain chance that you can get it back......"

"Then hurry up and find it!" Li Wanji said.

"It's not that simple. I have not studied in this area, I can only use the tools made by other companies to try to restore the fù, but in the future, I can't guarantee that I will be able to recover this article......

Fang Chang rolled his eyes, with an expression that I didn't expect.

Anyway, I was able to crack the password just now, and I guess it's a blind cat that ran into a dead mouse. Looking at the long progress bar, Fang Chang said, "I'll go back to the guard room first." ”

"What, are you going to release someone?"

"He has been cleared of suspicion, of course, he is released. Don't worry, I'll take care of it. ”

PS: I won't write thanks for tipping in the future, this is the last PS.

In addition, the suspense is too difficult to write.,IQ is limited.,Self-inflicted death can't live _(:з"∠)_
