Sanshuang Electronics Co., Ltd., located in the technical division of Seoul, South Korea, successfully found the reason why Sanshuang mobile phone could not be turned on, and also successfully proposed a solution. $().(23)(w)(x).()

Song Wenhua, a 22-year-old talented technical engineer, thought about it and said: "Mr. Zheng, this question, I can't answer. You should ask a professional, the experts in the network security department can answer."

Song Wenhua is not talking about it, but the truth. Although Song Wenhua discovered the reason why Sanshuang can't boot, and also know how to solve it. But Song Wenhua is only a hardware technical engineer, not a professional software development engineer.

How to write a software specifically for the recovery of the three cool mobile phones should be handled by the experts of the network security department, instead of letting Song Wenhua handle it.

Zheng Xiuhai turned and smiled at a middle-aged man: "Car Minister, how do you know how to solve this problem? How long does it take for the patch tool to be developed?"

The head of the cybersecurity department called Che Enjun, who was one year older than Zheng Xiuhai. He thought about it a bit. He did not immediately respond to Zheng Xiuhai, but whispered a discussion with a young man around him.

"Small pool, how long does it take you to look at it?" Che Enjun asked.

Inquired by Che Enjun is a young man who looks like twenty-seven eight. His name is Chi Chenghe. He is the chief technical expert of the Ministry of Cyber ​​Security. He is technically superior to the Minister Che Enjun.

"Minister, it takes at least an hour to keep it. It takes an hour and a half to be conservative. It will be completed by 8 o'clock at the latest." Chi Chenghe said.

Che Enjun nodded, although the technical aspect is not as good as Chi Cheng, but Che Enjun is not a technical white. Even the solution proposed by Song Wenhua is very simple. It's really easy to operate, but their repair environment is not the same as the user's repair environment.

With the internal testing instruments of Sanshuang, they can directly enter the bottom layer of the mobile operating system, or directly modify the source code. How can users do these things?

Therefore, they need to develop a patching tool. This tool needs to judge the existence of Sanshuang mobile phone when the Sanshuang mobile phone is connected to the computer through the usb cable. then. Also need to determine the connection of the three cool mobile phones, specifically what type.

The work of these two steps is very simple, but the third step is a bit more difficult. A patch tool is needed to scan the source code of the entire three cool mobile phone system and find the code that matches the 'shield wall'.

Once you find the code for the ‘Shield Wall’, you need to remove it from the phone system source code. If the code of the 'shield wall' is unchanged, then this step is very simple. But what if the code for the 'shield wall' changes?

Chi Chenghe considered this issue. Then I asked, "Song brother, if the code of the 'shield wall' will change, what should we do?"

Song Wenhua's face is unchanged, it seems that this problem has already been in his expectation.

"He Cheng Ge, I said before, the temporary patch tool. Just one of the programs, and it is a simple solution. Another program is more complicated. But it can solve any problem." Song Wenhua said.

Chi Chenghe asked: "What complicated plan?"

"We developed a three-six mobile phone management software. When the Sanshuang mobile phone connects to the management software through the usb cable, the management software re-writes the operating system for the mobile phone and deletes the original mobile phone system. So, rebuild After that, there will be no problems with the system. Moreover, no matter how the 'shield wall' code changes in the original system, it will have no effect.” Song Wenhua proposed a once-and-for-all solution.

"Management software? We Sanshuang company, there is currently a mobile phone management software, but there is no function to rewrite the system. Song Xiong, in fact, this program is the simpler method. Rewrite the mobile phone system, although It feels very cumbersome and time consuming, but it is the user's time. We only need to provide one-click function to write to the mobile phone system, and then show the user the remaining time, the user will not feel trouble at all." Chi Chenghe smiled Road.

The views of hardware engineers and software engineers really have some differences.

In Song Wenhua's view, it is very time consuming to rewrite the mobile phone hardware for the mobile phone hardware. And, it is also possible to burn the phone hardware. Because the user writes data using the usb cable, the current strength cannot be accurately controlled. In the unlikely event of abnormal current fluctuations, burning the phone hardware is not impossible.

In addition, re-writing the mobile phone operating system, the user's original information, certainly can not be saved. From the perspective of Song Wenhua, this approach is indeed more complicated and less scientific.

But Chi Chenghe is a software engineer. In Chi Chenghe's view, it is the best way to solve problems once and for all. As for the risk of rewriting the system, that is the user's business. As long as the interests of most users are guaranteed, the interests of a small number of users can be ignored for the time being.

As for the user information that Song Wenhua is worried about, it is actually not a problem. Because the three cool mobile phones are not unable to boot, but are blocked by the ‘shield wall’ code. If they are connected via the usb cable and the Sanshuang mobile management software, they add a data backup function to the management software.

After consulting with the technical department and the network security department, they chose the second processing solution, directly re-writing the operating system for the mobile phone, and adding data backup function, which is the best of both worlds.

Do not!

There should be a third benefit, that is, writing mobile management software to rewrite system functions and data backup functions, it only takes half an hour, it does not take more than an hour, and can be completed up to seven o'clock.

For Sanshuang Electronics, the current time is really very expensive. The sooner the third cool mobile phone can't be turned on, the more difficult the stocks of Sanshuang Electronics and Sanshuang Group will be solved. The reputation of the three cool mobile phones can also be recovered.

Shi Lei has been paying attention to the situation of the Nanchao Sanshuang Company, meanwhile. Mu Shuang also told Shi Lei at any time about the situation of the stock market in the Southern Dynasty.

"Shi Lei, the stock of Sanshuang Electronics Co., Ltd.. The total decline has reached 31. 7 percent!" Mushuang's tone, with a surprise.

Shi Lei smiled and said: "Frost cream, those international hot money have joined us?"

"Not for the time being! However, it is some local investors in the Southern Dynasties. They chose to smash the fire to the Sanshuang Electronics Co., and joined the ranks of our short-selling Sanshuang Electronics Co., Ltd.!" Mu Shuang said with contempt, as if ridiculing the Southern Dynasty Investor of the country. Not united and not patriotic.

In fact, such a situation, if it happens in Xia Guo. It is not surprising at all. Compared with the disunity of the Southern Dynasty, Xia Guoren should be better? Otherwise, how can there be a Xia Guoren is a dragon, two Xia Guoren are two insects?

This kind of trait is in any country. Especially in the capital market that focuses on interests.

“Hey? How much capital has the state added to our team in the Southern Dynasties?” Shi Lei asked curiously.

Mu Shuang has a clothing assistant. As for the situation in the stock market of the Southern Dynasty, she is quite clear. She directly gave a data. "Not much, it is only a little more than 100 million US dollars. It should be some private investors and private funds. If the stock of Sanshuang Electronics continues Falling, or Sanshuang Electronics can't handle the problem that the mobile phone can't start, there will definitely be more capital, choose to target Sanshuang Electronics and the entire Sanshuang Group."

"Well! Frost cream. Rest assured, three cool those sticks. How could it be my opponent?" Shi Lei said with a smile.

However, as if it were a face-lifting, Shi Lei had just brag about Mushuang, and he gave a reminder.

"Private r, the official website of Sanshuang Company, published a user announcement, indicating that Sanshuang Company has successfully solved the problem that Sanshuang can't boot."

Because this matter is related to the work of Shi Lei and Mu Shuang, the notification information is parallel processing thread, that is to say, Yi Shi also informed Shi Lei and also informed Mu Shuang.

Sure enough, after listening to the notification message, Mu Shuang immediately said to Shi Lei, "Shi Lei, Sanshuang is indeed not your opponent!"

Shi Lei said: "Frost cream, you wait a moment, I will first deal with the problem of Sanshuang company!" After the completion, Shi Lei immediately opened the official website of Sanshuang Electronics Co., Ltd. to view the user announcements they posted. .

......

"Full recovery, impeccable! 》

Dear three cool users, hello!

We are deeply sorry for the failure of the three cool phones to start. After investigation by our company, it was found that the event that the three-shuang mobile phone could not be turned on on a large scale was a malicious attack by a hacker.

After the efforts of our company, we solved the problem one hour and seven minutes after the incident.

Please download the ‘Three Shuang Mobile Management Software’ from this page, or the official website of Sanshuang Mobile Phone, and install it on your personal computer.

After successfully installing the Sanshuang mobile phone management software, as shown in the figure, connect the Sanshuang mobile phone that cannot be started using the usb cable, then open the Sanshuang mobile phone management software and select the backup personal data.

Please backup the relevant information according to your personal needs. caveat! If the user does not choose to back up, all data on the phone will be lost.

After the data backup is completed, please choose to restore the mobile phone system, and the Sanshuang mobile management software will automatically restore the operating system of the mobile phone for the user. In particular, do not disconnect the usb cable while the phone system is being restored. Do not turn off the computer. Otherwise, Sanshuang will not be liable for serious consequences.

This software supports win system and mac system, temporarily does not support linux and Unix systems, please forgive me.

......

Shi Lei looked at the announcement of Sanshuang Company, and his expression was awkward. He thought that Sanshuang Company made various reactions and solutions, but did not expect that Sanshuang Company actually made a plan to rewrite the mobile phone system.

The mobile phone of the 2008 era is not the Android smartphone of the later generation. The system can be written casually. It is not easy to rewrite the mobile phone system of this era.

Shi Lei originally thought that Sanshuang Company would find the code of the 'shield wall' to develop a patch tool specifically for cleaning the 'shield wall' code, similar to the virus killing tool.

If Sanshuang really chooses such a solution, Shi Lei is ready to change the source code of the 'shield wall' and replace it with dynamic code. The dynamic 'shield wall' code can't be killed by the killing tool, which makes the three cool company patch tools invalid.

But Shi Lei is miscalculated!

Sanshuang was originally prepared to develop a patching tool. Even Song Wenhua has proposed such a solution, but it has been obstructed by the cybersecurity department.

The network security department is very clear about the similar compatibility of the killing tools, how bad the compatibility. So they can't adopt the patch tool solution.

So, in the end, I chose the most secure solution. Sanshuang's solution directly allowed Shi Lei to prepare a follow-up plan. However, how can Shi Lei be able to give up?

Sanshuang Company has chosen the most unexpected solution, so be prepared to endure the most unexpected ending!
