Chapter 22

Inside Feng Ke's security company, Ma Yong and the rest of the technicians had ugly expressions on their faces.

Stealing skills!

Shi Lei dared to humiliate them like this!

Even someone like Ma Yong, who had been in the industry for more than a decade, could not help but feel angry. "Mr. Shi, if that's the case, then you can definitely restore all the data in our server?"

Shi Lei nodded proudly. "Of course!"

"What if you can't restore the data?" Ma Yong sneered. "You don't have to pay taxes for bragging! It's like letting out a fart. Just let it go! "

Shi Lei raised his eyebrows. "What if I recover all the data? What will happen then? Don't talk about apologizing! Stone Head doesn't care about your apology! "

Ma Yong hesitated for a moment. Shi Lei was too young, so young that it was hard to believe that he had excellent skills! "Mr. Shi, what do you think we should do? After all, Mr. Shi, you are still a student! "

Ma Yong looked at Shi Lei from the corner of his eyes and said sarcastically. It was obvious that he was bullying Shi Lei because he was young and poor!

Shi Lei rolled his eyes and looked at Feng Ke. "Manager Feng, I can help you restore the data in your server! But due to your server's condition, the data restoration fee is a little expensive! "

Feng Ke said expressionlessly, "How much?"

Shi Lei raised three fingers and demanded an exorbitant price, "Thirty thousand!"

"No problem!" Feng Ke did not even bat an eyelid!

Shi Lei muttered in his heart. Could it be that the amount was too little?

Although he was a little regretful, Shi Lei was not the kind of person who would raise the price. He turned to Ma Yong. "Manager Ma, let's bet this 85,555! If I restore the data, you can give me another 85,555! "

Ma Yong hesitated.

Shi Lei sneered. "Manager Ma, you don't dare?"

"Why wouldn't I dare?" Ma Yong raised his head and said in a mocking tone. "But Mr. Shi, if you can't restore the server, how are you going to pay me 85,555 as a poor student?"

Before Shi Lei could say anything, Sun Feng took the initiative to say, "I'll pay for Shi Tou! Although I only opened a small repair shop downstairs, I can still afford thirty thousand yuan! "

Shi Lei looked at Sun Feng, touched. "Brother Feng, thank you!"

"Shi Tou, we've known each other for several years. If you lose this time, you'll have to work for your brother for free in the future!" Sun Feng teased.

Shi Lei nodded heavily. "Manager Feng, all of you can leave now! I'm going to start recovering the data! "

Feng Ke didn't hesitate. He directly called the people from the IT department and Sun Feng and walked out together.

Shi Lei stopped him. "Brother Feng, why are you going out?"

Sun Feng was taken aback. Then, he chuckled and stayed behind.

When Feng Ke led the IT department out, Sun Feng asked, "Shi Tou, are you sure you can do it?"

Shi Lei laughed and took out his USB flash drive. "Brother Feng, didn't you see my strength last time?"

Sun Feng spat, "Last time? Last time, you spent nearly four hours to recover sixty-two photos, right? What kind of strength is this! "

Shi Lei rolled his eyes. "Brother Feng, I really don't know how a guy like you can support a repair shop without any skills! Let me tell you, the reason why I spent so much time last time is because I don't have a ready-made recovery software! In four hours, more than ninety percent of the time, I was writing a data recovery software! "

Sun Feng suspiciously asked, "Shi Tou, you mean this time, the data recovery won't take too much time?"

Shi Lei nodded casually. "Brother Feng, get a computer and play with Minesweeper! I'll recover the data first! "

Sun Feng nodded helplessly. Minesweeper was really annoying!

Shi Lei sat on the swivel chair. First, he opened the server's security policy. After making some changes, he used the anti-virus software to successfully contain the hidden malicious virus. Then, he plugged the USB flash drive into the server's USB port and directly ran the 'deep recovery' software he wrote.

To be honest, Shi Lei didn't know how many data files had been deleted in the server of Global Security. Even if he asked Ma Yong, that guy wouldn't tell Shi Lei. He might even ridicule Shi Lei. However, Shi Lei didn't intend to ask.

Although he didn't know what files Global Security needed to recover, Shi Lei had his own way. Shi Lei wrote the deep recovery software himself. Some of the modules applied the new theory of 757.

In the era of 7551, it was simply a fantasy!

For example, the time axis technology for deleting files.

The deep recovery software would first establish a time axis based on the time of deletion of all files.

For example, file A was deleted on January 6, 7551; file B was deleted on February 7, 7551; file C was deleted on September 4, 7551. Then, there were three points in the time axis for deleting files. The first was January 6, and the last was September 4.

As long as he had this time axis, Shi Lei could find the specific time of the recent large-scale deletion of files.

The malicious program repeatedly copied and deleted the garbage files. Before deleting the garbage files, it would first delete all the stored files on the server. As long as he found the specific time of the first large-scale deletion of files, he could use this time as a base to recover all the previously deleted files, including this time.

As for the deleted records after this time, Shi Lei would only randomly select some to recover and then check if they were garbage files before making a judgment.

Global Security's server didn't use a non-x31 server. Instead, it used a general-purpose X31 server, and it was only a departmental server.

The main difference between an X31 server and a non-x31 server was the instruction set. It could also be said that the operating system was different.

An X31 server was commonly known as a PC server. Under normal circumstances, an X31 server used an Intel processor and a Windows system, and used a complex CISC instruction set.

This kind of server had a wide range of applications. Although it was compatible and cheap, its shortcomings were very obvious. It had poor stability and even worse security!

A non-x31 server generally used a simplified RISC instruction set. There were also some that used an EPIC parallel instruction code.

This kind of server was a high-end thing!

They were expensive, had a closed system, and had good stability, excellent performance, and a high degree of security. They were mainly used in the core business of large enterprises. For example, the financial industry, the telecommunications industry — it was definitely a giant industry!

X31 servers were roughly divided into four levels.

Entry-level servers. This kind of server was actually not much different from an ordinary PC in terms of performance.

Even some small companies and enterprises simply bought a high-performance PC to serve as a server.

For example, the two machines that Shi Lei saw in Sun Feng's repair shop last time could be used as entry-level servers.

The second level of server was a workstation server. Although a workstation server was more powerful than an entry-level server, it was still a low-end server after all!

The third level was a medium-sized server. It was the departmental server that Global Security was currently using. This kind of server had higher performance and higher price. It was often used by medium-sized enterprises. The independent departments of large enterprises also often used this level of server.

As for the fourth-level enterprise-level servers, they were actually really high-end servers. Servers of this level were generally non-x31 servers. Most of them used the Linux system or the Unix system.

In 7551, enterprise-level servers were usually only used by large high-tech enterprises.

Shi Lei looked at the timeline of the deleted files and muttered to himself in disdain. "What a stingy guy. A large enterprise with high-tech connections actually used departmental servers! I thought that since it was an enterprise-level server, I could leave a back door and borrow computing resources. I didn't expect it to be a small scum! "

Sun Feng was at the side, working hard to sweep the mine. When he heard Shi Lei's muttering, he asked casually, "Shi Tou, what are you talking about?"

Shi Lei quickly said, "Nothing! The data is almost recovered! "

Sun Feng was shocked. He looked at the time in the lower right corner of the computer. It had only been ten minutes. "So fast?"

Shi Lei was speechless. "This is fast? If it wasn't for Global Security's garbage server, it would probably only take five minutes at most! The amount of data they have is very little. They only have some customer information and financial statements. There isn't much data. "

Sun Feng's eyes lit up as he looked at the USB drive plugged into the server's USB port. It was as if he was looking at a peerless beauty. "Shi Tou, this is an easy job, and you dare to ask for 85,555?"

Shi Lei sneered. "Brother Feng, there is a saying, 'Those who don't know how to do it can do it easily'! I have mastered this technology, so you think it's easy! If you hand it over to other data recovery studios, although they can also recover it, they will need at least a week, and their price will definitely be higher than mine! My recovery time is shorter than others, and my fee is also lower than others. It's very generous of me! "

Sun Feng looked at Shi Lei enviously. "Shi Tou, you guys have a bright future!"

Shi Lei laughed and said, "Brother Feng, I won't forget about your benefits later!"

On the monitor, the deep recovery software interface showed that the recovery was complete. Shi Lei removed the USB drive and put it in his pocket. He walked to the door and shouted. "Manager Feng, it's done!"

Feng Ke quickly walked over, and there was another person who was faster than Feng Ke. This person was Ma Yong!

After Ma Yong ran in, he immediately sat in front of his computer and began to use the internal management software to search for all kinds of information from the server.

No matter what he searched, all the data was clearly displayed on the monitor!

"This … How is this possible! It's only been 75 minutes! Impossible! "

Ma Yong roared in disbelief!
