Chapter 1506

HK1486 is fully restored and impeccable?

.

Samsung Electronics Company, located in the Technical Division of Nanchao Nation Seoul City, successfully found out why the Samsung Cellphone could not be turned on, and also successfully proposed a solution.

Two 12-year-old Genius technology Engineer Song MunHua, thought about it, started talking: “Section Head Zheng, this issue, I can’t answer. You should ask the professional person, the Cyber ​​Security Department’s Specialist to answer.”

Song MunHua is not talking about it, but telling the truth. Although Song MunHua discovered the reason why the Samsung Cellphone could not be turned on, and also knows how to solve it. But Song MunHua is only a Hardware Technical Engineer, not a professional software development engineer.

How to write a software specifically for recovery and rescue of the Samsung Cellphone should be handled by the Cyber ​​Security Department’s Specialist, rather than by Song MunHua.

Zheng SuHae turned and smiled at a middle-aged man: “Section Head Che, how do you know how to solve this issue Right? Patch Tool, how long does it take to develop?”

The Cyber ​​Security Department’s Section Head is called Che UnJun. It is older than Zheng SuHae First Year. He thought about it a bit. He didn’t immediately respond to Zheng SuHae, but whispered to a youngster around him.

“Little Chi, how long does it take for you to see?” Che UnJun asked.

Asked by Che UnJun is a young man who looks like Twenty-seven VIII, named Chi SeungHyeog, who is the Chief Technical Expert of the Internet Safety Department, simply in the technical aspect, even surpassing Section Head Che UnJun.

“Section Head, it takes at least an hour, it takes an hour and a half to be conservative, and it will be accomplished by 8 o’clock in the evening,” Chi SeungHyeog said.

Che UnJun nodded. Although the technical aspect is not as good as Chi SeungHyeog, Che UnJun is not technical Little Bai. Even if the solution proposed by Song MunHua is simple, it is really easy to operate. But their repair environment is not the same as the user’s repair environment.

With the testing instruments inside the Samsung Company, they can go directly to the bottom level of the cell phone Operating System or directly to the modify source code. How can user perform these operations?

So, they need to develop a Patch Tool that requires the Samsung Cellphone to exist when the Samsung Cellphone is connected to the computer via a USB cable. then. Also need to determine the connection of the Samsung Cellphone, which model is specific.

The work of these two steps is very simple, but the Third step is a bit more difficult. You need the Patch Tool to scan the source code of the entire Samsung Mobile Phone System and find the code that matches ‘Shield Wall’.

Once you find the code for ‘Shield Wall’, you need to remove it from the Mobile Phone System source code. If the code of ‘Shield Wall’ is unchanged, then this step is very simple. But what if the code for ‘Shield Wall’ changed?

Chi SeungHyeog considered the issue and then asked, “Brother Song, if the code for ‘Shield Wall’ will change, what should we do?”

Song MunHua complexion unchanged. It seems that this issue has already been in his expectation.

“Big Brother SeungHyeog, I said before, Temporary Patch Tool. It’s just one solution, and it’s a simple solution. Another solution is more complicated. But it can solve any issue.” Song MunHua said.

Chi SeungHyeog asked: “What complicated plan?”

“We developed a Samsung Cellphone Management Software. When the Samsung Cellphone connected to the Management Software via a USB cable, we re-written the Operating System for the cell phone through the Management Software. The Mobile Phone System with the original issue was deleted. So, rebuild After the System, there will be no issue. And no matter how the ‘Shield Wall’ code changes in the original System, it will have no effect.” Song MunHua proposed a once-and-for-all solution.

“Management Software? Our Samsung Company, currently has a cell phone management software, just doesn’t have to re-write the functionality of System. Brother Song, in fact, this solution is the easier way. Rewrite the Mobile Phone System, Although it is very cumbersome and time consuming, it is all user time. We only need to provide one-click writing to the Mobile Phone System, and then show the remaining time for the user, the user will not feel trouble at all.” Chi SeungHyeog laughs The road.

The views of the Hardware Engineer and the Software Engineer are really different.

In Song MunHua’s view, rewriting the cell phone operating system for cell phone hardware is very time consuming. Also, it is possible to burn cell phone hardware. Because user writes data using a USB cable, the current strength cannot be accurately controlled. In case of abnormal current fluctuations, burning cell phone hardware is not impossible.

In addition, re-writing the cell phone Operating System, user’s original data, certainly can not be saved. From the perspective of Song MunHua, this approach is indeed more complicated and less scientific.

But Chi SeungHyeog is a Software Engineer. In Chi Seung Hyeog’s view, it is the best way to solve the issue once and for all. As for the risk of rewriting to 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 data issue that Song MunHua is worried about, it is not an issue. Because the Samsung Cellphone is not bootable, it is blocked by the ‘Shield Wall’ code. If connected via the USB cable to the Samsung Cellphone Management Software, they add a data backup function to the Management Software.

After consulting the Technical Department and the Cyber ​​Security Department, they chose the Second processing solution, re-written the Operating System directly for the cell phone, and added the data backup function, which is the best of both worlds.

Do not!

There should also be the advantage of Third, that is, writing cell phone Management Software to rewrite the System function and data backup function, it only takes half an hour, it does not need more than an hour, and can be accomplished up to seven o’clock.

For Samsung Electronics Company, the current time is really expensive. The sooner the Samsung Cellphone can’t boot, the stock dilemma of Samsung Electronics Company and Samsung Group Company, the easier it will be. The reputation of Samsung Cellphone can also be recovered.

Shi Lei has been following the situation of Nanchao Nation Samsung Company. At the same time, Mu Shuang also tells Shi Lei about the situation of Nanchao Nation Stock Market.

“Shi Lei, the stock of Samsung Electronics Company, has fallen by 30% by a factor of seven!” Mu Shuang’s tone. With a surprise.

Shi Lei smiled and said: “Shuang Shuang, those International Floating Capital joined us?”

“Not yet! However, it is Nanchao Nation. Some local investors chose profiting from somebody’s misfortune to join Samsung Electronics Company and join our Short Sell Samsung Electronics Company Stock!” Mu Shuang said with a slight scorn, as if An investor who ridiculed Nanchao Nation. Not united and not patriotic.

In fact, such a situation, if it happens in Xia Nation, is not surprising at all. Compared to the disunity of Nanchao Nation, should the Xia Nation be better? Otherwise, how can a Xia Nation person be a dragon, and two Xia Nation people are two insects?

This kind of trait is in any Nation. Especially in the interest-oriented Capital Market.

“Hey? How much capital does Nanchao Nation have in our team?” Shi Lei curiously asked.

Mu Shuang has Izual assistance. The situation is quite clear for Nanchao Nation Stock Market. She gave a data directly. “Not much, only a little more 100 Million US Dollar. It should be some private investors and private funds. If it is Samsung Electronics Company’s Stock continues to fall, or Samsung Electronics Company can’t handle the issue that cell phone can’t start, there will definitely be more capital, choose for Samsung Electronics Company and the entire Samsung Group Company.”

“Èn! Shuang Shuang. Rest assured, Samsung’s those Stick’s. How could it be my opponent?” Shi Lei said with a smile.

However, as if it were a face, Shi Lei just blew niú bāi to Mu Shuang, and Izual issued a reminder.

“Sir.Samsung Company OffiCIA l Website Home, released user announcement, indicating that Samsung Company has successfully resolved the issue that Samsung Cellphone can’t boot.”

Because this matter is related to the work of Shi Lei and Mu Shuang, the notification is that the information is Parallel Processing thread, and in other words, Izual also informed Shi Lei and also notified Mu Shuang.

Sure enough, after listening to the notification, Mu Shuang immediately said to Shi Lei, “Shi Lei, Samsung Company is not your opponent!”

Shi Lei said: “Shuang Shuang, you wait a moment for a while, I will go to the Samsung Company’s issue!” After that, Shi Lei immediately opened the Samsung Electronics Company’s OffiCIA l Website home page to see what they posted. User announcement.

……

“Full recovery, impeccable! 》

Hello, Esteemed’s Samsung user!

We apologize for the issue that Samsung Cellphone cannot start. After our investigate found that this Samsung Cellphone was unable to boot on a large scale, it was a Hacker malicious attack event.

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

Data After the accomplish is backed up, please select the user to restore the Mobile Phone System, and the Samsung Cellphone Management Software will automatically restore the cell phone’s Operating System for the user. In particular, do not disconnect the USB cable while the Mobile Phone System is being restored, do not close the computer. Otherwise, Samsung Company will not be liable for serious consequences.

This software supports WinSystem and MACSystem, and does not support Linux and UnixSystem for the time being. Please forgive me.

……

Shi Lei looked at the announcement of the Samsung Company, and the expression startedled. He thought about the Samsung company’s all kinds of reactions and solutions, but did not expect that the Samsung Company actually made a solution to rewrite the Mobile Phone System.

2008 year’s cell phone, is not a later Android smart machine, System casually write casually, this year’s Mobile Phone System, want to rewrite is not easy.

Shi Lei originally thought that the Samsung Company would find the code for ‘Shield Wall’ to develop a Patch Tool specifically for cleaning the ‘Shield Wall’ code, similar to the Virus Exclusive Killing Tool.

If the Samsung Company really chooses such a solution, Shi Lei is ready to change the source code of ‘Shield Wall’ and replace it with dynamic code. The dynamic ‘Shield Wall’ code naturally cannot be killed by the Exclusive Killing Tool, which invalidates the Samsung Company’s Patch Tool.

But Shi Lei lost forget about it!

Samsung Company was originally prepared to develop the Patch Tool, and even Song MunHua has proposed this solution, but it has been obstructed by the Cyber ​​Security Department.

Cyber ​​Security Department is very clear, similar to the Exclusive Killing Tool, how bad the compatibility. So they can’t use the Patch Tool solution.

So, in the end, I chose the most secure solution. The Samsung Company’s solution directly allowed Shi Lei to prepare a follow-up solution. However, how can Shi Lei be willing to give up?

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