Riding the wind of rebirth

Chapter 1447: Sealing and directional training

This maintenance authority is the highest authority. Each dongle has an independent serial number, and each serial number corresponds to an independent first-level secret key. This first-level secret key is dynamically generated and is different every week.

Therefore, before each maintenance, the company's technicians need to retrieve the first-level secret key of this week's dongle from the server, and then take this secret key to the card unit to perform maintenance. It is safe, but it is troublesome.

So some "smart people" secretly buried such a backdoor to facilitate their own maintenance.

By adjusting the system time, you can skip the step of entering the first-level secret key and directly obtain senior administrator rights. After completing the work, you can change the time back to the normal time. It is really simple and efficient.

But once this secret is discovered, efficiency becomes funny.

Xiang Yu keenly discovered this bypass, and then his intuition told him that this bypass would never be useless and appear here inexplicably, so he tried to write a program to traverse some sensitive times.

Then I discovered the mechanism to obtain the highest maintenance rights of the dongle.

The next thing is simple. You only need to turn the Hanka and dongle into assembly language code through a disassembly tool. You don’t need to read and study thoroughly. Simply add an assignment statement before the clock reading bypass program to give By hard-writing the system time variable as 0:00 in 1900, you can enter the advanced maintenance mode of the dongle and read the content required for this command from Hanka using the maintenance authority.

Then recompile this set of things into executable code, which becomes a set of pirated Hanka programs that can be used for free by the whole world.

Solving this problem is actually very simple, and there are many methods. The simplest is to directly cancel the backdoor, or to give the dongle a maximum number of times it can enter maintenance mode per day.

But the reason why BUG is called BUG is that before it happens, you often have no idea how it will happen.

It itself is not something that can happen in a normal thinking mode, so you will never be able to test it in a normal thinking mode test.

Strictly speaking, Yu Lai should not be blamed for this, but should be shouldered by the smart guy who installed a backdoor into the dongle for the convenience of maintenance.

This approach is something that Hu Tianyu's team likes to do very much. It is also the most headache-inducing management issue for Zhou Zhi in the process of transforming from guerrillas to regular army.

At this moment, Zhou Zhi even somewhat absurdly missed the Japan-South Korea joint working group. The Hanka project was not under their surveillance, and then something like this happened. It was really dumbfounding.

However, things finally became clear. Xiang Yu was the one being exploited in this incident. The staff of the publishing house only told him that it was for the convenience of his work. Anyway, the company had already paid the money, and it was up to him whether he could crack it or not. It's about the unit.

Afterwards, he gave Xiang Yu 500 yuan.

Xiang Yu was very happy at first, but when he spent almost all the money on a dinner party and buying gifts for his girlfriend, the more he thought about it, the more he felt something was wrong.

He didn't dare to expose himself, so before leaving school, he secretly wrote an anonymous letter to Clover Company, telling the company that the bug had been discovered.

But he thought the matter was too simple. After receiving this letter, Mai Mingchuan paid great attention to it. When he saw that the postmark was Xi'an, and Xi'an was the only one that purchased the full-code character library Hanka, he notified several units. After checking, the pirates were immediately caught.

This matter can be big or small. The Xi'an agency company is already preparing to start legal proceedings. Fortunately, Zhou Zhi made the call in time, otherwise this matter would have really become a big deal.

Fortunately, Xiang Yu's letter was sent in time, and the pirated program has not been sold yet, which means it has not caused substantial harm to Clover Company. Therefore, it is at best a civil dispute and cannot be raised to the level of criminal punishment.

If Xiang Yu's anonymous letter was counted as meritorious service, there could be more to say.

Civil disputes adhere to the principle of "people do not take action and officials do not investigate", so Zhou Zhi requested that the matter be handled in a low-key manner on the grounds that the matter was a "family scandal" that should not be publicized. He rushed to the incident before it happened and sent technicians in the name of regular maintenance. All units should close this backdoor and reserve the right to hold the publishing house staff responsible and silence them. As for the college student, he might as well sign an agreement, which is just a targeted training agreement, in exchange for keeping quiet.

After all, he is a talented person. Since he likes to do this, let him study hard and research in this direction. From now on, he will intern in the company's independent laboratory every holiday and come to work in the company after graduation.

After the exchange with Lao Mai, about twenty minutes had passed. After putting down the phone, Zhou Zhi found that the Motorola casing was a little hot.

"Is it about Xiang Yu?" Jiang Shuyi asked. She had been staying quietly beside Zhou Zhi just now, so she could get an idea.

"Yes, he discovered a backdoor in Hanka, and then cracked it, and was almost used by bad guys." Zhou Zhi was relieved: "Now that we understand clearly, if Clover doesn't pursue it, nothing big will happen."

"Then you ask Professor Mai just now to call Xiang Yu's school and express his attitude." Jiang Shuyi took Zhou Zhi's hand: "Lest the school insist on punishing Xiang Yu."

"No need to fight. I asked Professor Mai to sign a closed directional training agreement with Xiang Yu. This must go through the school so that the school can understand the company's attitude."

"That's good." Jiang Shuyi breathed a sigh of relief.

"Stop talking about him." Zhou Zhi took the opportunity to talk to Jiang Shuyi: "Shu Yi, I miss you so much..."

"Don't..." Jiang Shuyi fled in panic: "It won't look good if they come out and bump into each other later..."

Thinking of Jiang Shuyi's character, Zhou Zhi had no choice but to give up: "Then I'll ask them to come out and call home. You teach them how to fight."

"Ah."

Back in the singing hall, Liang Hong was singing Feng Feifei's "Dream Chaser" with Zhang Xinyi.

When it comes to the singing skills among the friends, it goes without saying that Guan Tingting is the best. The best remaining ones are Ye Xin, then Zhang Xinyi, and Liang Hong and Jiang Shuyi can only be called average.

Now Zhang Xinyi is leading Liang Hong to sing, but Ye Xin is holding Wei Fei to teach him how to dance.

Zhou Zhi came to the boy's side and said to Zhang Lu and Fang Wenyu: "It's okay, Xiang Yu, this kid, poached me and came to my place. I'll treat him next time I catch him!"

Fang Wenyu actually didn't know how big a deal Zhou Zhi had done now. He only knew that Hanwenku was related to him, so maybe Zhou Zhi could talk about that Hanka.

I asked casually, but I didn't expect it to be solved, and I was very happy.

Zhou Zhi started grabbing peanuts and throwing them into his mouth: "You go find Shu Yi and call home."

Wei Fei also threw peanuts into his mouth like Zhou Zhi: "Commander, just go. I don't need it. In the middle of the night, my dad had to run across the playground to the communication room to answer the phone. It would be troublesome if he fell in the dark."

Although it makes sense, it is clearly an excuse for Wei Fei to be lazy, so you can't blame Zhou Zhi for finding a reason to scold him.
