Wang Xueba System

Jennifer watched Luo Hao operate the mouse, click the "Start Attack" button on the screen, and sneered in her heart. She has added a server with a hardware firewall and an IPS system for monitoring. I don't believe you can attack directly.

The defense of this server was weak before, because the competition organizing committee only had basic protection in order to reduce the time wasted by the national teams on it. However, now, the competition organizing committee wanted to "test" the technical level of Xia Guo team I won't hold back any more.

Moreover, since Luo Hao started writing the code, this delayed live broadcast has become a real-time live broadcast. The organizing committee has to verify the Xia Guo team in front of the whole world, especially in front of the other nine countries. Is the technology so high?

However, Jennifer's sneer soon stiffened on her face.

The moment Luo Hao clicked "Start Attack", on Luo Hao's computer screen, an ancient warrior in armor and holding a spear suddenly appeared, riding a white horse, and rushed out.

Then, within a minute, Luo Hao's computer screen changed - it became the server of the program group.

Jennifer picked up the phone, looked again at the screenshot of the server's current interface sent to her by the organizing committee, and recalled the image that suddenly appeared on Luo Hao's screen just now, and cold sweat suddenly broke out on her forehead.

"How did you get in so quickly? Could it be that I read it wrong? Or, this is not the interface of that server at all, but the same operation interface just happened to appear?" Jennifer comforted herself in her heart, but, Even she couldn't believe it herself.

"The 60 ip addresses were originally recorded like this." Luo Hao looked at the records on the server.

The organizing committee of this competition didn't have any good intentions either, this has already surpassed the difficulty just now.Luo Hao sneered in his heart, it seems that behind the organizing committee of this competition, it may also be manipulated by the beautiful country.This country, which likes to make small moves secretly, really does not miss any chance.

In this server, a small program is opened, which contains a piece of program code.

This code is mixed with different loops, and the results of these loops, after output, are the IP addresses of the hosts.

"Hehe, this little trick is really out of the question." Luo Hao shook his head, looked at Tantaiyue and the others beside him, "I don't know if they have heard a saying about our Xia Kingdom."

"What allegory?" Bai Ling asked cooperatively, and the others also looked at Luo Hao suspiciously.

"Hehe, the toad crawls on the feet—it doesn't bite anyone!" Luo Hao said with a chuckle.

"Hahahaha, that's appropriate!" Sun Yi was the first to laugh out loud.

"Indeed, it makes sense." Meng Fei also looked at Luo Hao's computer screen and nodded.

Jennifer was a little dazed by the sudden laughter, not to mention that her Xia Guoyu is not good, even foreigners who can speak a little Xia Guoyu may not be able to understand the meaning of this allegory.

"You just broke through the server provided by the organizing committee, so you can't be so happy?" Jennifer's voice sounded, "Next, you need to obtain the IP addresses of another 60 hosts, and then transfer the IP addresses of those 60 hosts at the same time. The mainframe needs to be compromised."

"Don't bother Jennifer the judges, I know all of this." Luo Hao turned to look at Jennifer, "It's just some simple loops, anyone in our country who has learned programming can get those 60 IP addresses .”

"As for breaking through those 60 hosts, well, I hope you will protect those 60 hosts more tightly, at least better than the protection of this server, otherwise, it will be meaningless at all." Luo Hao showed a brilliant look at Jennifer. smile.

"Hmph, who wouldn't talk big? You'd better do what you're doing, to save yourself embarrassment and accuse someone of bothering you." Jennifer curled her lips and became disgusted with Luo Hao, feeling secretly upset in her heart. These Xia people all know how to speak quickly. After a while they fail, I want to see if they can still be as eloquent as they are now.

Luo Hao looked at Jennifer and smiled, without speaking, but turned to look at the computer screen.

"Well, it's really insidious. There are traps in these loops." Luo Hao saw something unusual in these codes.

If it is a normal and complete code, you only need to run it directly to get the result, but these codes are basically only a part, and the compiler cannot directly run the result at all.

Moreover, individual loops have grammatical errors, which simply cannot get the final result.

Only a vague answer can be obtained. For example, there are two or three possibilities for one digit in an ip address. This means that there may be multiple ip addresses that cannot be determined. It can only be determined through experiments. Confirm manually one by one.

"It's really some little tricks that can't be put on the table." Luo Hao sneered, this little trap, that is, expanding those 60 IPs to more than 100 and less than 200 IPs, may cause trouble for others Some difficulties, but for myself, this matter is easy to handle.

Two methods, one is, regardless of Sanqi 21, directly attack these less than 200 IP addresses, as long as they really exist, and attack them all, and the other method is to see if this server is related to those 60 IP addresses. The machine has made a connection, and if there is one, there is always something to be found.

Luo Hao thought for a while, and it seems that the second method is a bit troublesome, but the first method is easier.

Directly break these less than 200 IPs directly, as to whether it will affect innocent people.

Luo Hao looked at the ip address and searched online, and found that it was basically a foreign ip address.Knowing this, Luo Hao felt relieved, as long as it wasn't Xia Guo's host, it had nothing to do with him.

After making a decision, Luo Hao quickly entered the less than 200 IPs into his program, and clicked the "Start Attack" button.

In an instant, the warrior sitting on the white horse with a gun reappeared, divided into countless figures, and rushed out.

After a pause of 1 minute, the figures of white horse warriors began to return one after another, standing in the center of Luo Hao's screen again.

Luo Hao looked back at Jennifer, then at the camera standing beside him, smiled, and said, "Today, I'll let you guys learn a lot!"
