Shuangqing City is a cosmopolitan metropolis as Xia Guozhong. The city directly under the jurisdiction of the central government, the status of Shuangqing City is equivalent to that of the independent. Establish provinces.

Therefore, the Western General Administration of the Cyber Security Bureau was established in Shuangqing City!

In the Western General Bureau of the Cyber Security Bureau, Ling Yuguo paid 1,000 Xia Guoyuan to the international account of the Union Bank of Switzerland, the parent company of Fantasy Technology, through the online payment system of Fantasy Technology, through the online payment system of Fantasy Technology.

When the online payment system shows that the payment is successful, a single . A 32-bit string of numbers and letters emerges, which is the authorization code for the Sakura virus data recovery tool.

Each authorization code can only correspond to one machine code, that is, it can only be used on one computer device.

Ling Yuguo copied the authorization code, followed the operation steps provided by the official website of Fantasy Technology, and first installed the data recovery tool in the USB flash drive. Then insert the USB flash drive into the computer device where you need to recover data.

The General Administration of the West tested the recovery of data, also a laptop. At this moment, on the screen of the laptop, pink cherry blossoms are flying.

When the USB flash drive with the data recovery tool installed is inserted into the USB port, a text typing box pops up in the dancing pink cherry blossom animation, prompting you to enter a 32-digit authorization code.

Ling Yuguo manually entered a 32-digit mixed authorization code of letters and numbers according to the authorization code he had just copied. Click the Confirm button.

The pink cherry blossom picture disappears, and the silver Infinity Möbius ring logo of Fantasy Tech appears, followed by a circular percentage display bar. There is also a text indicating that the data is being recovered.

Due to the test notebook of the General Administration of the West, there was basically no data on the hard drive, and the data recovery tool only took five minutes to recover all the data.

Ling Yuguo pushed the test notebook to Kong Yi, "Kong Yi, can you see if the data has been restored completely?" ”

Kong Yi, an expert in data encryption and data recovery, took a quick look at the data in the test notebook. This test notebook. It's still the test data he provides, so he knows the data very well. A moment later. He spoke: "Lingju, the data has been restored very completely!" ”

"Is it fully recovered? Is this fantasy technology company really that powerful? Or is it they who created the Sakura virus? Ling Yuguo seemed to be asking himself. Yang Lin, you take a look at this data recovery tool. Are there any system backdoors left? ”

Yang Lin is an expert on virus Trojans. If the data recovery tool will leave a backdoor program, Yang Lin can basically find out!

After carefully checking the test notebook, Yang Lin shook his head and said, "Lingju, no backdoor program was found." Just now I checked the system and it is clean and has not been changed. In addition, the data recovery tool does not hide the behavior pattern of the network, and it is tentatively concluded that it is safe! ”

Ling Yuguo was still not at ease and said, "Let's test it thoroughly together." There are also problems with the command system of the Rongcheng Military Region. It's a must-have! ”

Rongcheng Municipal Taxation Bureau. Xiao Zhao rushed to the bureau overnight, bringing his notebook and a USB flash drive with the Fantasy Technology data recovery tool installed.

The director of the tax bureau personally took the lead in working overtime, can other personnel not work overtime? As a result, all the personnel of the entire tax bureau arrived at the tax office.

In the office, the tax commissioner looked at Xiao Zhao and said, "Xiao Zhao, have you really found a way to recover data?" ”

Xiao Zhao nodded, and then said with some embarrassment: "Director, although the method has been found, this method is not free. Companies that provide data recovery need to charge a certain fee. ”

The director of the tax bureau said indifferently: "As long as the data can be recovered, the fee will be charged!" ”

"Director, the price of data recovery is a bit expensive!" Xiao Zhao said embarrassedly: "It will cost 1,000 yuan to recover!" ”

"1,000 yuan?" The tax commissioner originally thought it was too expensive! I didn't expect it to be just a thousand yuan! "Xiao Zhao, let's start recovering data! It's just 1,000 yuan, and our bureau has reimbursed it! ”

Xiao Zhao coughed and said: "Director, it's 1,000 yuan for a computer, not 1,000 yuan for all recovery!" ”

"What?" The tax commissioner immediately called the director of the office and asked, "Director Guang, how many computers are there in our bureau?" ”

Director Guang thought for a while and said, "Director, there are a total of one hundred and thirty-two!" There is also a primary server and a standby server. ”

Xiao Zhao calculated: "One hundred and thirty-four computer equipment, a total of 134,000 yuan, Director, will it be restored?" ”

The tax commissioner gritted his teeth and said, "Recovery!" Not to mention more than 130,000, even 1.3 million, we have to recover! ”

"Got it!" Xiao Zhao also knows the severity of the matter, if the information stored by the tax bureau is lost, the loss is calculated according to 100 million yuan!

At the same time, a large number of enterprises purchased data recovery services from Fantasy Technology. Some enterprises with a large number of computer equipment also try to purchase one or two hundred authorization codes, and then reverse calculate the generation law of authorization codes.

However, the authorization code designed by Shi Lei is a randomly generated 32-bit mixed string of numbers and letters, and there is no half-point rule at all. After each 32-bit string is generated, the corresponding authorization code is stored in the database of Server 1.

When the authorization code is used to activate the data recovery tool, it will automatically connect to the database of the first server for automatic comparison. If there is a corresponding authorization code, the data recovery tool will be activated.

So no matter how those guys who try to steal and cheat, how to calculate the generation law of the authorization code, they can't make a tool like the authorization code generator!

On the side of Jingyayuan, Shi Lei observes the official website of Fantasy Technology at any time to prevent it from being maliciously hacked by others, and also to prevent malicious tracking by some people.

When the time was close to 0:00 in the morning, Shi Lei inquired about the international accounts of UBS and Mirui Technology, and found that he had earned more than 30 million Xia Guoyuan!

A computer costs 1,000 yuan, more than 30 million yuan, just more than 30,000 computer equipment!

Shi Lei believes that as time goes by, more and more money will definitely come in. But Shi Lei also has a worry in his heart, in this cherry blossom virus disaster, fantasy technology has made too much money!

It's not a good thing for fantasy technology!

If someone else mistakenly thinks that Fantasy Technology is the creator of the Sakura Virus, it will have a bad impact on Fantasy Technology!

After Shi Lei thought about it, he gave up washing and sleeping, and instead opened the programming software, ready to write a cherry blossom killer!

Sakura Killer is also a computer virus, but unlike other computer viruses, Sakura Killer will only look for Sakura virus in the Internet, and then forcefully remove Sakura virus.

When they can't find the Sakura virus on the Internet, they start to clear themselves.

After half of the compilation, Shi Lei hung an announcement on the official website of Fantasy Technology, indicating that Fantasy Technology was trying to find a way to completely eliminate the cherry blossom virus.

It was close to three o'clock in the morning, and Shi Lei still didn't go to sleep. Instead, he continues to write Sakura Killer, as well as maintain the official website of Fantasy Technology.

The official website of Fantasy Technology has been maliciously attacked intermittently, and if there is no defense from Shi Lei, I am afraid it will be attacked. It's just a pity that the Rock Firewall doesn't work.

The Rock Firewall is on the blacklist of the Wosang Country, and the Sakura virus is developed by the Vosang Pink Sakura, in case the International Intelligence Bureau of the Ministry of Foreign Affairs of the Wosang discovers the Rock Firewall, then Shi Lei will be unlucky!

In an all-nighter time, Shi Lei finally completed the development of the Sakura Killer. Log in to UBS and check the bank account of Mi Rui Technologies.

On the monitor, the available balance of the bank account, a long list of numbers is displayed!

Looking at this long list of numbers, Shi Lei was shocked!

He counted it several times, and finally confirmed that there were nine digits before the decimal point!

Xia Guoyuan: 103,223,000.00!

One hundred and three million two hundred and twenty-three thousand dollars!

"100 million!" Shi Lei patted his face vigorously and muttered to himself: "Could it be that I have stayed up all night, and I am dazzled?" ”

Rushing into the bathroom, Shi Lei wet his head with cold water, and after checking in the mirror to confirm that he was awake, he returned to the No. 1 server!

I counted the number of available balances on the screen again, and sure enough, it was nine digits, more than 100 million yuan!

"Haha Shi Lei smiled and snorted coldly: "Pink cherry blossoms, pink cherry blossoms, should I invite you to dinner?" Or is it a share for you? ”

Wosang Guo, Pink Sakura was analyzing the data recovery tool developed by Fantasy Technology, and he deliberately exchanged 1000 Xia Guoyuan for Japanese yen, purchased an authorization code, and checked the recovery effect of the data recovery tool.

Judging by the results of the test, Pink Sakura was devastated!

"Who is behind the fantasy technology? Completely interpreted the cherry blossom tree gene blueprint of the cherry blossom virus! Pink Sakura frowned, unable to believe the facts in front of her. When he was about to hack into Fantasy Technology, the firewall of the computer suddenly sounded an alarm!

In the Western General Bureau of the Cyber Security Bureau, after a night of struggle, Ling Yuguo, Ding Qiudun, and Yang Lin jointly analyzed the Sakura virus data recovery tool, and repeatedly confirmed that the data recovery tool did not have any backdoor, so they immediately provided a solution to the Rongcheng Military Region and reported the specific situation to CNS.

CNS has investigated everything about Fantasy Technology, starting with Mi Rui Technology. Due to legal issues in the Cayman Islands, CNS was unable to investigate the specific situation of Mi Rui Technology, and had to return to China to investigate.

Fantasy Technology was registered in Shuangqing City, and they quickly found Shi Lei's body

Shi Lei was looking at the more than 100 million yuan in the international account of the Union Bank of Switzerland, smirking stupidly, but he immediately thought of an important question.

Fantasy Technology has made so much money, I'm afraid that the domestic CNS, as well as the four major cyber security bureaus, want to check his old bottom, right? .
