In the office of the Dongbin City Public Security Bureau and the network security department, Luo Ju inserted the USB flash drive with a trembling hand and inserted it three times before inserting it. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

After getting the USB flash drive, he didn't even have time to rush back to the capital, so he immediately planned to find a place to try.

It's just that too many computers and systems are now paralyzed, and the more you delay, the more serious the loss.

So, he drove directly to the public security department in Dongbin City, found a paralyzed computer, and planned to try it.

Next to them, the two young men from Netan looked at each other and said in a low voice: "Luo Ju...... Couldn't it be that someone fooled him...... I've never heard of this ransomware being able to be decrypted......"

Several directors of the Dongbin City Bureau who were accompanying him heard it and frowned: "Don't talk nonsense!"

"Uh......" The young policeman shrank his head and took a step back.

Who would have thought that Luo Ju also heard it, he smiled and took a breath, turned his head to look at the directors and said, "Theoretically, this young man is right......

"Is there really no way to crack it?" In the past few days, the people of the Dongbin City Public Security Bureau have also been anxious, and they were stunned when they heard this, they are not engaged in the Internet, so they naturally don't understand why this is happening, "Doesn't it say that if there is a spear, there is a shield? Why can't it be cracked?"

The customs of Dongbin City is probably the busiest customs recently, and the dignitaries of various countries and company executives are desperately running to the Lazy God Island, queuing up to wait for the Lazy God Department to receive them, after the outbreak of the virus, the entry and exit departments are paralyzed, and I don't know how many people are furious at the customs.

But is it not just one or two sectors that will be affected?

As a last resort, Dongbin City can only return to the ancient paper file system, turn out the old paper pile to print and archive various documents, manual checking, manual management, although the efficiency is a little low, but at least it can restore the functions of the department.

But this is just a drop in the bucket, not to mention, now the entire system is networked across the country, and in the case of network paralysis, there are really very few things that can be handled.

I have to say that a small outbreak of the virus has already begun to affect national security.

"Explain, young man. Luo Ju looked at the young policeman and said.

"Well, it's not that the virus can't be cracked, but the amount of computation required is too great, which involves information theory, the principle of encryption and decryption of information, and it is very troublesome to talk about without a foundation in cryptography...... To put it simply, the virus first randomly generates a pair of public and private keys for the infected machine, first expands the key itself, and then encrypts and stores it with the RSA 2048 algorithm. Then the public and private keys are destroyed, and the encrypted key is used to encrypt the computer files with AES......"

Several bureau chiefs listened in circles, and they almost slapped this young man and asked him to speak.

The young man also found that he had spoken too deeply, and hurriedly said: "This involves the principle of the virus, the virus is not to delete your files, but to encrypt your files, just like we pass the secret file, no key can not be cracked, if you want to crack the virus, you must use brute force to crack it, that is, use the exhaustive method, exhaustive all possible ......" The young man said.

"Then let's do it!" said a director, "I know this, excluding all the impossibilities, the rest is the suspect......"

"It's taking too long......"

"How long?"

"With our kind of computer, time is calculated in millions of years......" This time there was no need for the young man to answer, Luo Ju answered, he patted the ordinary office computer beside him, and said.

"Then I understand!" A director nodded again and again: "The supercomputer of the lazy god department is very powerful, they use supercomputing to crack the password!"

"This is also impossible...... the young man shook his head, "Director, even if it is the computing power of the young lazy god, it will take at least fifty years to crack the key...... And the key used by each computer is different!"

The directors of the "Fifty Years ......" were speechless, and in the end, only one sentence of hatred remained: "Hackers are really hateful! Don't let me catch you!"

Luo Ju shook his head helplessly, what's the use of saying cruel words now? The other party is not an ordinary hacker, there are several shadows of countries behind him, even if the evidence of the crime is conclusive, these countries have the power to make these people disappear out of thin air, or even never appear again.

For now, I can only choose to believe in this so-called cracked program.

Luo Ju took a deep breath, opened the USB flash drive, clicked on the program, double-clicked, and then a window popped up.

A line of words appeared on the screen: "Oops! Uncle cop is here! Little hacker, don't let me catch you!"

At that moment, they thought it was a virus that had encrypted the program, and a few tortured police uncles almost pulled out their guns and punched the computer!

In the next second, a cartoon character wearing a little snitch in black crawled out of the window, and before he could escape, a policeman wearing a power exoskeleton fell from the sky.

Next, the cartoon cop began to beat the snitch.

Left hook right hook, up and down split roundhouse kick, took out two guns and shot wildly, and the little hacker played bullet time......

The expressions of several directors were like this: "......"

However, in addition to the animation, the data stream is also frantically swiped in the window: "The key is being generated, and the ...... is being decrypted"

"Word document: Household registration form 2015 is being decrypted, decryption is completed ......"

"Excel document: The high temperature subsidy distribution form is being decrypted, and the decryption is completed......"

"Excel Document: Condolence Payment Form for Injured Persons in the Line of Duty......"

"JPG Document: Mayor's Inspection (Option 1)" ......

The little hacker tilted his ass and got into the waterfall-like data stream, and then the little policeman chased him in, and after a while, he threw him out of the shoulder, and the two animated images hit from the top to the bottom, the bottom to the top, and even took out the rocket launcher to shoot at each other......

A group of big men stood there, staring at the screen, their eyes drifting around with the two villains, and after about ten minutes, the waterfall stopped, and the little hacker was beaten into a sieve, dragging the little hacker's body away from the screen.

"Decryption complete. Four big words appear on the last line of the data stream.

"Have you taken a look at the decryption?" said several bureau chiefs in a hurry.

The young policeman took a deep breath and clicked on a form on his desk.

The screen flashed, the Office logo popped up, and after a few seconds, the table opened.

"It's ...... Solved?" Luo Ju was overjoyed, pushed the little policeman away, and clicked on other documents himself.

He has tried all these files, they are all encrypted, and they can't be opened at all.

"Unraveled! This one unraveled! This one unraveled!" several files were opened in succession, and a group of people were dumbfounded.

Didn't you say that even if it was a young lazy god, it would take decades to unravel?

This shared ...... More than ten minutes, right?

How does this little program do it?

But now is not the time to explore this.

"Publish this decryption program and hang it on the ministry's website!" Luo Ju said excitedly.

"Yes!" The little policeman licked his lips and was about to send things out, but Luo Ju suddenly stopped him again: "Wait, that animation...... Can you get rid of it?"
