Desperate Hacker

Chapter 189 Let It Go

"Your files have been locked, please pay the ransom as soon as possible if you don't want to lose anything!"

Chen Qingfeng looked at the locked files and frowned.

But so far, he has determined that the virus weapons used by his opponents are developed on a completely new platform.

Simply put, this thing contains 4 modules.

Multiple algorithm encryption mechanism.

That is to say, if you want to rely on brute force operations to unlock the file.

You must overcome one difficulty after another, and there are multiple cryptographic problems standing in front of you.

Without the participation of quantum computers, it is simply impossible to unravel these encryption measures.

In addition to this is the ransomware module. Chen Qingfeng has not seen any ransomware modules from other companies.So it's unclear whether this is controlled by the network or directly programmed into the program.

In addition, there is also an operating system, that is, when you try to use violence to solve the problem, the other party can also give you a joint destruction and directly delete all the data.

The last item is also the question that Chen Qingfeng is most interested in, that is, how did the opponent infiltrate?

This is also the only place where Chen Qingfeng can start so far.

He is a hacker and has a large number of zero-day vulnerabilities.Therefore, it is not difficult to investigate the other party's penetration method.

But this time, Chen Qingfeng felt that the virus did not penetrate directly from outside the server.

Chen Qingfeng quickly logged into the company's network management system.

Then the clues were discovered immediately!
The company's huge business network is supported by products from telecommunications companies.

However, when he tried to access the company's network management software, he unexpectedly discovered that his administrator rights were restricted!
"interesting!"

"What's the matter, Old Chen?"

"The other party is an expert and used a new vulnerability that I don't know about. This is how they succeeded. They first found a way to access our company network, and then obtained partial permissions of the network management operating system. I don't know what means they used. , directly raising the permissions to the root level! Then they can see our entire network topology and architecture, and then wait for them to take action!"

Chen Qingfeng's words surprised everyone.

Zhou Yaojie didn't understand it.

Of course, he also probably understood the opponent's successful strategy!

"Are you saying that all our office networks are now under each other's surveillance?"

"Yes, what the other party really controls is not our server data, but the network! They intercepted it through the network, which made me mistakenly think that we really couldn't get the permission of the server! But in fact, this guy used a little trick. Your subordinates When the network administrator logged into the server for the first time, he could actually do it, but he played a trick and caused the network to return wrong information. But in fact, this information was returned by the routing and relay devices in the network. …”

"You mean, we handed the password to each other with our own hands!"

"Yes! These people are very smart, surprisingly smart, and they have obviously played tricks on all of us!"

When Chen Qingfeng thought about this, he suddenly realized a problem.

So he quickly called and dialed Ding Jiancheng's number.

"Old Ding, are you still at the school? How is the current situation?"

"The situation on the school's side is not serious for the time being. After all, it's just the school's external server that has been damaged. By the way, Lao Zhao said they have a problem there too!"

"Old Ding, will you tell these people immediately not to log in to the server with administrator rights?"

"What do you mean?"

"Don't do this if you are not logged in! Because the opponent is waiting for you to do this. The administrator rights they really control come from the network operating system. I still don't know how they obtained this authority. , but it may be an undiscovered vulnerability! They intercept the information on the network, and then deliberately convey some wrong information to you! As long as you do not choose to log in to the server with administrator rights when the network is connected, your There will be no problem with the data!" "I don't understand, what should I do now?"

"Disconnect the infected network. I remember that the school's external website should be independent. First cut off this part of the network from the school's important network. Then you can find a less important system and try as I said. one time!"

……

It turns out that everything is a deception.

But this did let Chen Qingfeng learn a lesson.

At this time, he had already guessed his opponent's methods.

……

After Ding Jiancheng put down the phone, he immediately called Zhao Lidong.

Zhao Lidong was already very worried.

But none of them dared to move because the data from the Department of Agriculture was too important.

If it is leaked abroad, it will be equivalent to leaking a series of important data such as Zhejiang Province's grain production this year, as well as mountains and rivers, Heze, etc. abroad.

By then Zhao Lidong's career, if not over, would at least be stagnant.

At this moment, Zhao Lidong received a call from Ding Jiancheng.

"Old Ding, how is the situation?"

"Chen Qingfeng called me just now and said that the operating system of the network device should be infected?"

"The operating system of the network device?"

"Yes, you haven't tried to log in remotely while connected to the Internet, right? It's best not to do this. First, disconnect the infected operating system from the network, and then try to access the server's permissions?"

"No, won't you send someone over? Who will be responsible if something goes wrong?"

"Old Zhao, are you still thinking about these things now? Otherwise, don't listen to me..."

"No, no, no, now, my place is a mess. I really can't afford anything if something happens!"

"Then you listen to me and give it a try first to see if what Chen Qingfeng said is right? Find an unimportant system and see if you can log in and access it normally. If you can... then it means what Chen Qingfeng said That’s right!”

"Chen Qingfeng? Is he reliable?"

"Anyway, I have been troublesome with him these days, and he has never let me down. Lao Zhao, you are really good at being an official, but sometimes you are too careful..."

Zhao Lidong was suddenly reminded by Ding Jiancheng, and he suddenly realized a problem.

The current crisis is not only a matter that may affect his career, but also an opportunity, and Zhao Lidong needs to give it a try in the Department of Agriculture to establish his prestige!

After putting down the phone...

"Director Zhang!"

"Zhao Chu!"

"Old Zhang, is there any system that is irrelevant? Disconnect that system first, and then try to access the server!"

"Chief Zhao! We have contacted people from the data company..."

"Contact, they are useless! If I ask you to try, just try. Find an insignificant system server. It's done. If there is really no impact, just disconnect all the networks..."
