There are many ways to compromise a system:

1. Illegal exploitation of system files

Vulnerabilities in the design of the operating system open a backdoor for hackers to enter your computer through this backdoor.

2. Falsification of information attacks

By sending forged routing information, the source and destination hosts of the system are constructed with fake road strengths, so that the packets flowing to the target host pass through the attacker's system host, so that sensitive information and useful passwords can be provided.

3. Remote manipulation

An executable program is launched on the compromised host, which displays a fake login screen. When the user enters the login information on this disguised interface, the program transmits the information entered by the user name to the attacker's host, and then closes the interface to give a system failure prompt, asking the user to log in again, and then the real login screen will appear.

4. Exploit the mistakes of the system administrator

Hackers take advantage of the system administrator's mistakes to collect attack information, such as using commands such as finger, netstat, arp, mail, grtp, telnet, and some hacking tools

5. Ethernet broadcast attacks

Ethernet is used as an excuse to use scramble mode to intercept all packets in a local area for your own use.

6. Data-driven attacks

A data-driven attack occurs when a seemingly innocuous special program is sent or copied to a network host and executed to launch an attack. For example, a data-driven attack can cause a host to modify files related to network security, making it easier for hackers to hack the system next time.

However, there are many solutions to these.

But the technology Jiang Fan mastered was not something they could solve.

Unless Jiang Fan himself is willing to stop, then the invasion will stop, otherwise, the virus will continue to invade, and when the time comes, it will also cause a large area of paralysis.

And what Jiang Fan used was also a computer virus, which set a scope, and only attacked the system that dealt with his own company.

Wu Junming took Xiaohua and went to the company.

As soon as Xiaohua entered the program department, she began to do it and tried to crack it, but unfortunately she tried for more than an hour, but it still didn't work.

And in this hour's time, the paralysis of the hesitation system, Wu Junming's company, lost hundreds of thousands.

Wu Junming is not only this company, but also other companies, if you count other companies, then in this hour, you have lost a lot of 100 million.

If he continues like this, and the system is still paralyzed in one day today, then he will lose almost 500 million today.

lost 500 million in one day, plus the billion that Lin Zhengping transferred to him, this is not a grade at all.

Moreover, the company's losses are so large, the stock market will also be implicated, and when the time comes, the investors of their companies are afraid that they will also withdraw their capital and no longer invest in their companies.

Wu Junming rubbed his temples, and he had a headache.

If this matter is not dealt with quickly, then everything will become more difficult as things develop.

It seems that the only way to contact Jiang Fan is to make him stop.

Wu Junming sighed, the development of things was beyond his thoughts, and now he had to bow his head and admit defeat.

"Xiaohua, stop, don't get it, you help me find Jiang Fan's contact information, I'll call him personally." ”

"Okay, godfather. ”

Xiaohua inquired about Jiang Fan's contact information, and it didn't take long for her to tell Wu Junming.

Wu Junming got the contact information and called without hesitation.

"Hello?"

"Mr. Jiang, I'm Wu Junming. ”

"Oh, Wu Junming, I don't know. ”

"Mr. Jiang, I asked my goddaughter to invade your company. ”

"Oh, it's you, what's the matter?"

"Mr. Jiang, this matter is something I did wrong, I am here, I apologize to you, I hope you can withdraw it, and don't let our company's system collapse again. ”

"Oh, how do you think I did this?"

"Mr. Jiang, my goddaughter, has already told me that these things are precisely from Mr. Jiang's means, I don't know Mr. Jiang, what do you have to do to stop it?"

"I haven't played enough, how can I just stop like this, Wu Junming, if you want to play, I can continue to play with you. ”

"Mr. Jiang, I won't play anymore, this matter, I didn't do it right, I shouldn't have promised Lin Zhengping to make a move on you, I hope you can forgive me, as long as you withdraw these, I can compensate you." ”

"Compensation, do you know, I, Guangyao Group, because of your company's invasion, in just ten minutes, I lost one billion. ”

"Lean !!"

When Wu Junming heard this, his breathing suddenly became short, and in just ten minutes, he lost one billion? I'm afraid you're kidding.

How could it be that so much time was lost?

But he didn't dare to say such a thing.

"Then let's do it, Mr. Jiang, I am willing to compensate you 1.5 billion, please stop. ”

"It's only 1.5 billion, so little? Lin Zhengping asked you for help, it should be more than 1.5 billion, right?"

"Mr. Jiang, Lin Zhengping asked me to make a move, and it only cost a billion. ”

"One billion, I didn't expect Lin Zhengping to be so rich, tsk. ”

"If I knew this, I might as well go directly to Lin Zhengping, pretend to be a hacker, and help him. ”

"Mr. Jiang, don't joke anymore, you say, you make a price, as long as I can accept it, I will compensate you. ”

"Since Mr. Wu is so sincere, so be it, I'll give you a discount, three billion. ”

"Three billion, Mr. Jiang, why don't you go and grab it!" Hearing three billion, the corners of Wu Junming's mouth twitched, and he blurted out excitedly.

"Mr. Wu is unwilling, since he is unwilling, then I don't have to talk about it. ”

"Mr. Jiang, wait, wait, I, I'm willing, it's just three billion, I can't take so much for a while, I need time to prepare. ”

"You are very rich, three billion, for you, it will only take two or three years to earn it back. ”

"Three billion, give you two days, hit my account, if you don't see the money, your company, wait for bankruptcy." ”

"You can also call the police, but if you can find out if I did it, then I don't know. ”

Wu Junming's mind turned, he didn't think about calling the police, but Jiang Fan's methods were obviously several times more powerful than his own goddaughter, even if he called the police, if he couldn't find out that Jiang Fan did it, then things would only become more troublesome.

Thinking of this, Wu Junming gritted his teeth: "Okay, Mr. Jiang, give me two days, I will transfer three billion to you, and please stop." ”

"Yes, if I don't receive the money in the past two days, then you know the consequences. ”

"My account is 。。。。。。 ”

After talking about the account, Jiang Fan hung up the phone, and a minute after he hung up the phone, Wu Junming's company system was restored to the same as before.

Seeing that the system had finally recovered, Wu Junming breathed a sigh of relief, and soon frowned again.
