Chapter 1191: Beating
In the office of the network security department of the Dongbin City Public Security Bureau, Director Luo inserted the USB flash drive with trembling hands, and it took him three times to insert it.
After getting the USB flash drive, before he even had time to rush back to the capital, he immediately planned to find a place to try it out.
It is true that too many computers and systems are paralyzed now, and the more the delay continues, the more serious the loss will be.
So, he drove directly to the public security department of Dongbin City, found a paralyzed computer, and planned to try it.
Next to it, two young men from Internet security looked at each other and said in a low voice, "Ju Luo...could he be fooled by someone...I've never heard that this kind of ransomware virus can be decrypted..."
The directors of the Dongbin Municipal Bureau who were with me heard this and frowned, "Don't talk nonsense!"
"Uh..." The young policeman shrank his head and took a step back.
Unexpectedly, Bureau Luo heard it too, he took a breath with a smile, turned his head to look at the directors and said, "Theoretically speaking, 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 were also in a state of distress, and they were taken aback when they heard this. They are not engaged in the Internet, so naturally they don't understand why this is the case, "Isn't it said that where there is a spear, there is a shield? Why can't it be cracked?"
The customs in Dongbin City is probably the busiest customs recently. Political leaders and company executives from various countries ran desperately to Lanshen Island, waiting in line to be interviewed by the Lanshen Department. After the outbreak of the virus, entry and exit The departments are paralyzed, and I don't know how many people are furious at the customs.
But more than one or two departments are affected?
As a last resort, Dongbin City can only return to the ancient paper file system, dug out the old paper piles to print and archive various documents, manually check and manage them. Although the efficiency is a bit low, at least the functions of the department can be restored.
But this is just a drop in the bucket, not to mention, the entire system is now connected to the national network, and when the network is paralyzed, there are really very few things that can be handled.
It has to be said that a small outbreak of the virus has already begun to affect national security.
"Young man, please explain." Luo Ju looked at the young policeman and said.
"Uh, it's not that viruses can't be cracked, but the amount of calculation required is too large. This involves information theory, the principles of information encryption and decryption, and it's quite troublesome to talk about without a foundation in cryptography... To put it simply, viruses are first randomly generated. For the pair of public key and private key of the infected machine, the key itself is expanded first, and then encrypted and stored with the RSA 2048 algorithm after generation. Then the public key and private key are destroyed, and the encrypted key is used to encrypt the computer file with AES... "
The directors turned their eyes in circles when they heard this, and almost slapped the young man to make him speak humanly.
The young man also found that what he said was too deep, and quickly said: "This involves the principle of viruses. A virus does not delete your files, but encrypts your files, just like we pass confidential files. There is no encryption. The key cannot be cracked. To crack the virus, you must use brute force, which is to use the exhaustive method to exhaust all possibilities..." The young man said.
"Then exhaustive!" A director said: "I know this, rule out all the impossibilities, and the rest are suspects..."
"It's taking too long..."
"how long?"
"Using our computer, the time is calculated in millions of years..." Luo Ju answered without the young man this time. He patted the ordinary office computer beside him and said.
"Then I understand!" A bureau chief nodded repeatedly: "The supercomputers of the Lazy God Department are very powerful, and they use supercomputers to crack passwords!"
"This is also impossible..." The young man shook his head and said, "Director, even with Qingda Lazy God's computing power, it would take at least fifty years to crack the key... and the key used by each computer is It's all different!"
"Fifty years..." These bureau chiefs were speechless, and in the end, all they could say was, "Hackers are so hateful! Don't let me catch you!"
Luo Ju shook his head helplessly, what's the use of saying harsh words now? The other party is not an ordinary hacker. There are several countries behind them. Even if the evidence of the crime is convincing, 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 cracking program.
Luo Ju took a deep breath, opened the USB flash drive, clicked on the program, double-clicked it, and a window popped up.
A line of words appeared on the screen: "Oops! The police uncle is here! Little hacker, don't let me catch you!"
At that moment, they thought it was a virus that had encrypted the program. A few tortured police uncles almost drew their guns and shot the computer right through it!
The next second, a cartoon figure of a little snitch in black crawled out of the window. Before he could escape, a policeman wearing a powered exoskeleton fell from the sky.
Next, the cartoon policeman began to beat up the snitch.
Left uppercut and right uppercut, upper kick, lower chop and roundabout kick, took out two guns and shot wildly, the little hacker played with bullet time...
The expressions of several bureau chiefs are like this: "..."
However, in addition to the animation, the data flow is also frantically swiping in the window: "The key is being generated, decrypting..."
"Word document: household registration form 2015 is being decrypted, the decryption is complete..."
"Excel document: High temperature subsidy distribution form is being decrypted, decryption completed..."
"Excel document: Statement of Consolation Fund for Persons Injured on Duty..."
"jpg file: Mayor's inspection (choose 1)..."
The little hacker tilted his butt and got into the waterfall-like data flow, and then the little policeman chased him in, and threw him over his shoulder in a short time. Above, 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 back and forth with the two small men. After about ten minutes, the waterfall stopped, the little hacker was beaten into a sieve, and the little policeman dragged the little hacker's body away screen.
"Hey, it's so cool!" A policeman couldn't help but clenched his fist and said.
Luo Ju gave him a blank look.
"Decryption complete." Four large characters appeared in the last line of the data stream.
"Let's see if the decryption has been deciphered?" Several bureau chiefs hurriedly said.
The young policeman took a deep breath and clicked on a form on the desktop.
The screen flashed, and the office logo popped up. After a few seconds, the form opened.
"This is... solved?" Luo Ju was overjoyed, pushed the little policeman away, and opened other files by himself.
He has tried all these files, and they are all encrypted and cannot be opened at all.
"It's unlocked! This one is unlocked! This one is also unlocked!" Several files were opened in a row, and the group of people were dumbfounded.
Didn't you agree that even Qingda Lazy God will take decades to unravel?
This took... more than ten minutes, right?
How did 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 webpage!" Director Luo excitedly said.
"Yes!" The little policeman licked his lips, and was about to send something out, but Luo Ju stopped him suddenly: "Wait, that animation... can it be removed?"
