The office building rented by "Xingyue Technology" is very large, and it is also splendid, full of science fiction atmosphere.

People are sure to be in a very happy mood when they work here!

When Xu Qian walked into Xingyue Technology, our security guard brother recognized him, and the security guard brother was very enthusiastic to ask him for an autograph, and Xu Qian did not refuse to come.

When I entered "Xingyue Technology", I found that there were many new faces here, and now that the company has grown and grown, it definitely needs more vitality to work.

Xu Qian quickly found Kang Zhen and Intoxication.

Now both of them have some leadership style, especially Intoxicated and look a lot more mature!

Xu Qian asked, "What have you been busy with lately?"

Kang Zhen said: "Dong Xu, why did you come over without making a sound." ”

Intoxicated also said: "Xu Dong, you scared me a lot." ”

But then he said to Xu Qian mysteriously: "We are doing a big thing. ”

"Big deal?"

Xu Qian was a little curious.

Although Kang Zhen was very restrained, he couldn't hide the pride in his heart.

Xu Qian was even more curious, because he knew that Kang Zhenke was a very calm person, but now that he showed such an expression, it seemed that it was really a great thing.

"What's the big deal?"

Xu Qian asked.

Intoxicated, he said, "Didn't you let us study free antivirus software!"

Xu Qian nodded, yes, he did let Tao Zui and others study free antivirus software!

Because he saw the potential of antivirus software.

In other words, he has no choice, because this world already has TT and Qiandu, and he can't take food and wrestle with these two big brothers.

Even if he wants to, he can't pull these two big brothers!

So he was ready to take a different path and make free antivirus software.

In another world, 360 dares to fight against penguins.

Of course, it didn't do anything to a penguin.

But there is no shame in this, what a giant penguin is, and who dares to be tough with it, and 360 did it, although the process is tortuous, but it also shows his toughness!

This is like the second best man in the Sui and Tang dynasties, at least he can take a few moves from Li Yuanba, while others can't even take a single move from Li Yuanba, which reflects the gap.

That's why Xu Qian decided to make this free antivirus software, because it really has a lot of potential.

"Now we're pretty much done. ”

Intoxicated and happy.

Xu Qian was stunned: "That's all you said?"

This was originally something he expected, and it wasn't a big deal.

Xu Qian felt speechless for a while, this is still mysterious, as for it.

He even felt that they had spent a lot of time researching this free antivirus.

Of course, this is just Xu Qian's inner thoughts, as I said before, what he advocates is the "good person culture", and he is reluctant to scold others, for fear of damaging the enthusiasm of others.

Such a management model is unacceptable.

A tolerant management environment can stimulate the talent and creativity of others, but it is not good for the development of the enterprise!

Intoxicated smiled: "Do you think we have been making this antivirus software for a long time?"

Intoxicated laughs.

Xu Qian nodded.

Nima, when will this guy be able to read minds? He even knows what is going on in my heart。。。。。。。

At the same time, when he saw the appearance of intoxicated Guan Zi, he wanted to punch him.

"It's all because of a recent big event in the Internet world, which is why we have extended the production time of antivirus software!"

Intoxicated laughs.

"What's the big deal?"

Xu Qian asked angrily.

"Have you ever heard of ransomware?"

Intoxicated.

"Ransomware?"

Xu Qian fell into the memory.

This is a big news in China recently, this virus is raging in China, many companies have been blackmailed by this virus, even many public security networks are no exception, this virus is very terrifying.

The so-called ransomware virus is a new type of computer virus, which mainly spreads in the form of emails, program Trojan horses, and web trojans.

The virus is vicious in nature, extremely harmful, once infected will bring immeasurable losses to users, this virus uses a variety of encryption algorithms to encrypt files, the infected person generally cannot decrypt, must get the decryption of the private key to be able to crack.

Once a ransomware file is local, it runs automatically, and the ransomware sample is deleted to evade detection and analysis.

Next, the ransomware exploits local internet access to connect to the hacker's C&C C server, and then upload the local information, download the encrypted private key and public key, and use the private key and public key to encrypt the file. Except for the virus developer himself, it is almost impossible for anyone else to decrypt it.

After the encryption is completed, the wallpaper will also be modified, and a ransom message file will be generated in a prominent location such as the desktop, instructing the user to pay the ransom.

And the variant type is very fast, and it is immune to conventional antivirus software. The samples of the attack are mainly EXE, JS, SF, VBE, etc., which is a great challenge for security products that rely on feature detection.

Once the ransomware file is clicked on by the user, it will be exploited to connect to the hacker's C& C server, which then uploads the local information and downloads the encrypted public and private keys. Then, the encrypted public key and private key are written into the registry, and the Office documents, pictures, and other files in all local disks are traversed, and the format of these files is tampered with and encrypted. After the encryption is completed, a ransom message file will be generated in a prominent location such as a desktop to direct users to pay the ransom.

This type of virus can cause important files to be unreadable and critical data to be corrupted, which has a serious impact on the normal work of users.

It can be said that the recent domestic headlines have been dominated by "ransomware virus" and "virtual currency".

Xu Qian asked suspiciously, "What does this ransomware have to do with our antivirus software?"

Suddenly, his expression changed suddenly, and it became very exciting!

"You don't want to。。。。。。。。。。 ”

Xu Qian was a little shocked by the thoughts of intoxication and others.

Intoxicated smiled and nodded, "It seems that you have also thought about it." ”

"Yes, we just want to solve this ransomware and make our antivirus software an instant hit. ”

Intoxication is very high-spirited.

Now he is calm and well-adjusted, he is no longer the shy and shy programmer he used to be, he has grown, and now he can take charge on his own.

Kang Zhen added: "Because of this, it took us a longer time to research this antivirus software. ”

"Actually, antivirus software is not difficult, we have already successfully researched it, the difficult thing is how to solve the ransomware virus. ”

Kang Zhen said.

Xu Qian looked at the two of them in a bit of a daze, he still had a feeling of dreaming, these two people really gave him a big surprise!
