My Side Job is a Trader

Zhang Xin clicked in and took a look, and found that Zhang Daxian on the Internet was the screen name he had registered at the beginning.

"That's right, it's me. No, why am I on the hot search for no reason?"

Although Zhang Xin knew that it took him just over a month to develop a mature industrial drawing software that would definitely attract attention, but in his vision, this should only spread in the small circle of programmers. It will not appear in the eyes of ordinary people.

But soon Zhang Xin discovered the problem, that is, the hot search list data has not been updated, and there are only a few such cases, or the netizens are really awesome, and a large number of clicks and exposures make this topic continue to dominate the list, but seeing Ten articles are all on this topic, which is obviously impossible.

Either there is a major bug in Weibo, but Weibo is a big company anyway, there is no reason to say that it has not been discovered and fixed for several days.

The rest may be that Weibo has been attacked, and Weibo is obviously helpless at present.

Zhang Xin brought a laptop, and without avoiding Li Xueer, hacked into Weibo's server with a few swipes.

At this moment, a group of network security experts who were thinking of a way in the Weibo computer room suddenly discovered that another force had invaded the server.

Moreover, this person was upright and did not hide anything, just hacked Weibo's server in front of everyone.

When Zhang Yang heard the news, he was so angry that he dropped the phone in his hand, and shouted angrily, "Where is my Weibo? Is it a public toilet? Come and leave whenever you want?"

The heads of the network security departments of other companies comforted Zhang Yang. After all, the hot search list was locked, and Weibo was losing millions every day. Even Zhang Yang, who was already financially free, felt a little bit pained.

Zhang Xin quickly discovered the abnormal code hidden in an inconspicuous corner, so he specially wrote a patch for this code to completely isolate the code so that it cannot be connected with other normal codes. and interact.

After Zhang Xin quit, all those who checked Weibo suddenly found that Weibo was being forced to update. After opening it again, the hot search list became the usual news of entertainment stars.

After the network security experts in the server room received the news, they found that they could indeed manipulate all the data on the server.

Everyone looked at each other in blank dismay, guessing that there might be a mysterious expert solving their troubles for them, so at this moment everyone was thinking in their hearts, who is this person and why did he do this.

Someone boldly speculated: "Do you think this Zhang Daxian is solving this problem for us?"

"Well, it's possible. I've seen the case of Zhang Daxian, who completed the development of an industrial drawing software in a month, and there were no bugs. Some programmers I know highly admire Zhang Daxian. idols to worship, because Zhang Daxian wrote the code, not a single word is superfluous."

"So, this Zhang Daxian should also be a good person like Bai Ke?"

"Nonsense, I saw that many domestic enterprises and universities did not use industrial drawing software, and directly developed one, and it was also open source. This shows that I am a patriot who cares about my country. This person can take the opportunity to make a lot of money. , but it just opened up, which shows that people's minds have long since broken away from the realm of ordinary people like us."

"Then why come to attack our server again?"

"This is estimated to be two groups of people. Zhang Daxian is the one who helped us solve the problem. As for who the person in the front is and what they want to do, I don't know."

In the apartment in the suburbs of the capital, Song Ming suddenly shouted: "Brother Yu, Weibo has returned to normal. Does this mean that your method has been cracked?"

Peng Yu hurriedly turned on the computer, only to find that he had lost connection to the Weibo server.

"I'm afraid he made a move. Great, he finally noticed."

Next, Peng Yu tapped on the keyboard, and soon those who were browsing Weibo found a line of words appeared in the middle of the screen: "Master, can you tell me your identity, I want to learn a new algorithm from you."

Everyone tried to close this line of conspicuous text, but no matter what they did, they couldn't close it.

In the server room of the Weibo building, everyone expressed helplessness and could only hope that Zhang Daxian could find out the abnormality as soon as possible, and then come to solve the problem.

Moreover, they also felt dumbfounded about the hacker's purpose. Such a big commotion was just to learn new algorithms. It can be said that this hacker must be a person who loves to learn.

In the Shanghai stock market, Zhang Xin was just about to close the computer, but Li Xueer told him that Weibo had been attacked again.

When Zhang Xin saw the hacker staying behind, he immediately felt dumbfounded.

"Oh, my husband, you are more famous than those superstars now. They have made such a big battle just to learn some algorithm."

Zhang Xin said: "It is estimated that some fledgling young man made it up. I think this farce should be over."

So Zhang Xin used SHA encryption to display his company address on Weibo, and the user suddenly found that there was an extra line below, but unfortunately it was all garbled characters.

People who know a little bit about it will know that this is an encrypted string after seeing it.

Communication started up in the server room again.

"What's going on? Is this the SHA encryption method? It is said that the US FBI is also using this encryption method, but after SHA encryption, it cannot be cracked. How do hackers know what is written?"

"Maybe they have a method, such as using the enumeration method, try one by one, as long as the encrypted string is right, don't you know the content?"

"Are you stupid? Also enumeration method, do you know how many characters there are in Chinese characters, and how many combinations are arranged together? With the current calculation level, even with the most advanced supercomputer, it cannot be calculated, otherwise the SHA encryption method It won’t be called incomprehensible.”

In the apartment, Peng Yu saw an extra line of words on the Weibo interface, and after writing it down completely, he took the initiative to cancel the mask on the Weibo interface.

So the user found that Weibo was back to normal again.

At first, everyone was worried. After waiting for an hour, they found that everything was normal, so these network security experts breathed a sigh of relief.

"But if we encounter this situation next time, how should we deal with it? Can't we always expect Zhang Daxian to help again?"

"That's right, so we have to figure out a way to see if we can strengthen the perimeter defenses, and try to prevent hackers from reaching into the code. Keeping the enemy out is the last solution."

This person's point of view has been agreed by most people, so everyone added a group with each other, and everyone will communicate when they have time.

Seeing that the matter had been resolved, the group of network security experts also proposed to return to the company. Zhang Yang entertained everyone with a sumptuous lunch, and then let everyone leave.
