Lin Tian returned to the bedroom and hurriedly took a shower, and then turned on the computer, because on the way back, Lin Tian unexpectedly received a reminder from Xiao Zhi, saying that the new round of ransomware virus is mutating in an all-round way, and the number of infected people has increased by 2 times on the original basis!

Operating the Apple computer, Lin Tian first browsed the latest news about the virus on the Internet. But when I just opened the Baidu page, the firewall reinforced by Xiaozhi immediately sent out an alarm and intercepted an unknown virus.

Lin Tian set up a sandbox environment in the isolation area of the firewall, extracted the unknown virus, ran in the sandbox environment, and immediately found that the unknown virus was the latest mutated ransomware virus!

The fourth-generation ransomware virus is formed by the gradual mutation and mutation of the first-generation virus, and each generation is getting stronger and stronger.

Subsequently, Lin Tian asked "Xiaozhi" to shell the fourth-generation ransomware and check the file signature code and memory signature code of the ransomware.

In the process of "Xiaozhi" decomposition, Lin Tian found that this fourth-generation ransomware virus had undergone another mutation on the basis of the original, and it can be said that this should be the fifth time!

Lin Tian was slightly stunned in his heart, in just a few hours, the ransomware virus began a new round of mutation?

Checking the news on the Internet, Shi Lei found that a special tool for ransomware virus appeared on a science and technology forum, but when Lin Tian clicked on it, he found that it actually cost five yuan to download it once, and there was no trial version!

"What kind of broken software, there is not even an experience period, and the current software does not have experience time. Lin Tian complained secretly.

"Master, you don't need to pay attention to this killer software anymore, because it has lost its anti-virus effect. Ash suddenly reminded.

"What's going on?" Lin Tian asked.

"The latest virus mutations, this special killing tool can no longer detect and kill the new mutated viruses!" Ash explained.

"I see!"

It turned out that Lin Tian thought that this person or organization that developed a ransomware killing tool was so great, but he didn't expect it to be like this!

"Ash, if you were asked to solve this virus, would you be able to solve it?" Lin Tian asked.

"Of course, this AI can get rid of these viruses without much effort!" said Ash, arrogantly.

"What about the locked data and files, can they be unlocked and recovered?" Lin Tian asked again.

"Of course!" Ash said.

After hearing Ash's words, Lin Tian pondered for a moment, because he suddenly thought of a good way to make money, a shortcut to suddenly get a windfall.

Now that ransomware mutants are so rampant, there are countless infected users on the network, if you also develop a software that can effectively detect and kill ransomware......

One can completely remove viruses and keep disk data files, and the price is 100 yuan or more, which is not too much! After all, now the computer can be repaired for hundreds of yuan at a time. Now for a price of 100 to 100, you can remove viruses and restore unlocked files, which is really a good thing, a pie-in-the-sky thing!

Thinking of this, Lin Tian smiled evilly and said, "Ash?"

"Master, do you have any orders?"

"If you were asked to develop a special tool for killing ransomware in the network, would you be able to make it?" Lin Tian asked.

"Absolutely!"

"How long will it take?" Lin Tian asked again.

"An hour!"

"Okay, then you can do it! I'll go to bed first, I'm sleepy!" Lin Tian looked at the wall clock on the wall, then turned around and climbed into bed.

......

The night is silent, but it is not peaceful.

In the core of the ghost organization, in the internal communication channel, there are only four people online at the moment. They are cannon fodder, empty man, sissy cold-faced scholar, and two "ghost" undead and skeletons!

The cannon fodder empty man is the ghost organization is the core layer, ranking last, but he is not cannon fodder in the traditional sense, and his own computer strength is also very strong. It's just that every action is to hit him in the head, so over time he has the title of cannon fodder.

According to the grapevine, the empty man himself is a rich second generation, and his family has a listed company, so he basically has nothing to do every day, except for playing on the computer, just playing games.

"Undead, the forum said that our killing tool is useless, and now we are asked to return the money, what should we do now?" said the empty man.

The skeleton preemptively responded: "I'll go with the undead to take a look, it should be the ransomware virus that has mutated again, you have to be careful of your computer, don't get hit again!"

The empty man thought about it, his own computer level was really a little far from the third and fourth. So he said, "Okay, you guys go and see!"

......

The Zhongzhou General Bureau of the Cyber Security Bureau, Wu Zhenguo's eyes were bloodshot. He said tiredly: "The new round of ransomware virus has mutated and mutated, according to my observation, just now it has undergone another mutation on the basis of the original, and now a large number of public institutions and government departments have been attacked by the new mutated virus, and all office networks are paralyzed, what do you say now?"

Wang Lin, an expert in data encryption in the bureau, said: "Wu Bureau, after the ransomware virus mutated, according to the file feature code, after many days of calculation and research, I finally calculated some rules. However, the ransomware encryption method is neither a 64-bit mainstream key nor a 128-bit strong key. ”

If we don't know what rules the other party compiles based on, we can only collect a large number of file feature codes, as well as memory feature codes, and perform large-scale calculations, so that it is possible to reverse deduce the key. Wang Lin continued.

Wu Zhenguo waved his hand and said, "Okay, everyone." Now the virus has brought many adverse effects to society, so we must come up with solutions as soon as possible!"

......

On the other side, Lin Tian was asleep on the bed, and the computer on the other side of the screen was open, and a string of codes flashed on the monitor......

This kind of scene feels a little scary when you think about it, but where is this now, of course Ash is operating in the computer, and now it is developing a targeted killing software, and it is fundamentally to detect and kill, no matter how the ransomware virus mutates, it can't escape its pursuit.

More than an hour later, a software icon appeared on the screen of the computer, needless to say, it must have been Ash who developed the killing tool.

Subsequently, the computer screen goes out and the computer shuts down automatically!
