Wang Xueba System

After waiting for a while, Luo Hao found that the Association of Mathematicians didn't seem to reply to him, so he stopped paying attention to the emails on the computer.

After opening the software he wrote before, Luo Hao continued to study.

Before, Luo Hao used the pseudo-artificial intelligence program he wrote to attack the Great Wall Firewall he wrote. He wanted to test the two programs in this way to see how well the pseudo-artificial intelligence judged. Multiple attacks failed and downtime.

Luo Hao's instructions to the pseudo-artificial intelligence were also very simple, and he obtained a file named 11111.txt from the host computer protected by the Great Firewall.

And this test can also detect to a certain extent whether there are some loopholes in the defense of the Great Wall Firewall that he has not noticed.After all, the thinking of pseudo-artificial intelligence must be different from the attacking thinking of normal people. Maybe through the operation of pseudo-artificial intelligence, we can find problems that Luo Hao didn't notice under the influence of thinking inertia.

As a result, under this kind of operation, he really gained something.

Pseudo-artificial intelligence is attacking while searching for network security information on the Internet, but because it is a program after all, as long as it finds new network security knowledge, it will try to use possible loopholes in this area to find the Great Firewall. loophole.

After thousands of attacks by different methods, a loophole was finally discovered in the Great Firewall.

The core of the Great Firewall is mainly to judge whether visitors have permission to access, but in the original Great Firewall, Luo Hao did not add pseudo-artificial intelligence to judge, and it is still the most basic programming method used.

However, under the attack of pseudo-artificial intelligence, the original version of the Great Wall Firewall failed to judge in time. After receiving too many visits, the hardware judged that the program occupied too much hardware resources, which caused the processor to slow down and even limit the maximum resources of the firewall. occupancy quantity.

In this case, the host itself is under too much pressure, causing loopholes in the defense.

But in many cases, this situation is not necessarily avoidable, and it is also a headache for many network security companies.

This is also the reason why many websites will require the time interval for applying for a verification code when registering and applying for a verification code, once every 60 seconds, or once every 120 seconds.

However, Luo Hao feels that this method can still be used for verification codes, but it may not be practical for other places.

In addition to this problem, Luo Hao also discovered that after the Great Wall Firewall allowed another host to access this machine, the pseudo-artificial intelligence actually discovered this, and turned around and hacked the authorized host first. , and then using this host as a springboard, successfully accessed the host protected by the Great Wall Firewall, and uninstalled the Great Wall Firewall by remotely uninstalling the firewall.

This discovery made Luo Hao very distressed. Under normal circumstances, who would know which host or which IP address is allowed to access a tightly protected host?

But now that this problem has been discovered, Luo Hao has to solve it, so in the end, Luo Hao decided to combine the pseudo-artificial intelligence program with the decoding logic in the signal capture device, and let the Great Wall Firewall judge the transmission of each authorized host. Is there any problem with the data.

But this also greatly occupied the performance of the hardware, and then Luo Hao modified the judgment logic. Only the exe files that can be installed will judge whether the file is harmful, and other files will not make this judgment, and then the files within the specified range are not allowed to be judged. Modifying or deleting, etc., finally made up for this loophole.

Looking at the knowledge base of pseudo-artificial intelligence that has saved a lot of data in front of him, Luo Hao smiled and began to modify the program again.

............

On the other side, Twisted City, the headquarters of the World Association of Mathematicians.

"Damn it, that Luo Hao sent an email, asking when we will announce the standard answer." Hades looked livid, obviously very angry at Luo Hao's behavior.

"That's the only way to go now." Eli ignored Hades' words, just looked at the stack of calculation papers on the table in front of him, and sighed.

"How on earth did this Luo Hao solve this problem!" Hades heard this, his ugly face became even more gloomy.

"Is this issue still important?" Eli glanced at Hades, "The trouble you caused, but let me accompany you to clean it up."

"All the benefits are given to you, and you didn't come for nothing." Hades said angrily, "This answer can only reach this level for the time being. It would be great if there was more time."

"Hmph, enough time?" Ellie snorted coldly, "If you want to discredit the Association of Mathematicians and lose its reputation, it doesn't matter."

"Then let's announce it like this." Hades sighed, called the secretary over, and gave instructions.

Soon, a problem-solving process was published on the official website of the World Association of Mathematicians.

However, this time the World Association of Mathematicians is very low-key.The statement that was not issued like last time also caused some media to publicize it.

"Okay, next, it's time to discuss how we will deal with Luo Hao." Eli waited until Hades' secretary walked out of the office, looked at Hades, and said with a serious expression.

"How to face Luo Hao?" Hades suddenly turned to look at Ai Li, "What do you mean?"

"I don't think it's necessary to target Luo Hao anymore. He has passed the certification of a fifth-level mathematician, and his real level should be more than just a fifth-level mathematician." Ai Li looked at Hades and said coldly Said, "As the vice president of the World Association of Mathematicians, I think it is not a wise thing to continue targeting Luo Hao, and it will even seriously affect the development of the association!"

"Then what are you going to do? Just let him go like this?!" Hades was obviously reluctant, "Just keep silent like this and stop doing anything? Turn a blind eye to Luo Hao's actions against the association? Wouldn't this make things worse? Affect the reputation of the association?"

"But I don't want you to joke about the future of the association!"

............

Two fifth-grade mathematicians were arguing in the office like this, and Luo Hao didn't know about all this for the time being...

It wasn't until the next morning that Luo Hao saw the hot search on Weibo:

Hot Search No. [-]: Grade [-] Mathematician Exam Answers

The second hot search: Luo Hao

Hot search No. [-]: World Association of Mathematicians

Only then did Luo Hao know that the official website of the World Association of Mathematicians had published the answer to that question.
