Chapter 1447: Sealing and Targeted 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 The key is still generated dynamically and is different every week.
Therefore, before each maintenance, the company 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 for maintenance, which is safer. It's safe, but it's trouble.
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, and some sensitive times came up One pass.
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 the disassembly tool. There is no need to read and study thoroughly. Simply read the bypass program before the clock. Add an assignment statement and hard-write the system time variable as 0:00, 1900. Then you can enter the advanced maintenance mode of the dongle and read the content required for this command from Hanka using maintenance permissions. .
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 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 kind of 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 came to light. Xiang Yu was the one who was taken advantage of in this incident. The staff of the publishing house only told him that this was to facilitate his work. The company had already paid for it anyway. Whether or not to crack it is a matter for your own unit.
Afterwards, he gave Xiang Yu five hundred 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 did not 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 most a civil dispute and cannot be raised to the level of income. The height of punishment.
If Xiang Yu’s anonymous letter was to be counted as meritorious service, there would be more to say.
Civil disputes adhere to the principle of "people don't take action, officials don't investigate", so Zhou Zhi claimed that the matter was a "family scandal" that should not be publicized, and asked to handle it in a low-key manner, before it happened, in the name of regular maintenance. , first send technicians to various units to close the back door, and then reserve the right to hold the publishing house staff accountable and silence him. 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 talent. 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 by Zhou Zhi's side just now, so she could get an idea.
"Yes, he discovered a backdoor of Hanka, then cracked it, and was almost used by bad guys." Zhou Zhi was relieved: "Now I understand clearly, if Clover doesn't pursue it, it won't What’s the big deal?”
"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."
< br>"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 also understand the company's attitude."
"Then Okay." Jiang Shuyi breathed a sigh of relief.
"Stop talking about him." Zhou Zhi took the opportunity to talk to Jiang Shuyi: "Shuyi, I miss you so much..."
"Don't..." Jiang Shuyi He ducked away in a panic: "It won't look good if they come out later..."
Thinking of Jiang Shuyi's character, Zhou Zhi had no choice but to give up: "Then I'll call them out and call home. You teach them how to fight."
"Yes."
Back to the karaoke hall Here, Liang Hong is singing "Dream Chaser" by Feng Feifei 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, 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 to dance.
Zhou Zhi came to the boy's side and said to Zhang Lu and Fang Wenyu: "It's okay. This guy Xiang Yu came to my place. I'll catch him next time and ask him to treat me!"
Fang Wenyu In fact, I don’t know how big a deal Zhou Zhi has done now. I only know that Hanwenku is related to him, so maybe Zhou Zhi can speak for that Hanka.
I asked casually, but I didn’t expect that it was actually solved, and I was very happy.
Zhou Zhi started to grab peanuts and throw 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. My dad has to run across the playground to answer the phone in the communication room in the middle of the night. It's troublesome if he falls 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.
