Chapter 52

Access company, Mr. Xia's real name was Aiken. It was set up in 6439 and its headquarters was located in Voisin, Tokyo. It was mainly involved in management consulting, software development, mobile network services, internet browser, etc.

Access's flagship product, NetFront, was very popular on Voisin mobile devices!

This company, which was mainly based on the internet, had applied to Tokyo Institute of Technology to rent the use of Super Computer Yan.

After finding out about this, Shi Lei immediately used the internet to search for Aiken's homepage. You can get a lot of information from a company's homepage. For example, the company's current situation, the company's financial statements, and even the personal passwords of the company's members could be found from a company's homepage!

Shi Lei entered Aiken's homepage and browsed through the company's recent situation. This company has a lot of potential. NetFront's browser partners are NTT and Sony, the two giants.

After browsing for a while, Shi Lei tried to find a loophole in Aiken's homepage and entered the website. As an IT company, Aiken's homepage had its own server. It was not a rented server provided by an internet service provider.

After Shi Lei figured out the server's operating system, he immediately used an undisclosed loophole to enter the server. Aiken's homepage's server had a lot of documents stored inside. Shi Lei browsed through the documents carefully and finally found something that he was interested in.

Aiken did not rent much of Super Computer Yan's system resources. They had their own powerful server. The reason why they rented Super Computer Yan was to increase their company's popularity!

Surprisingly, Shi Lei managed to find the login account and password of the supercomputer Yan within the web server of Aiken. Aiken had released Super Computer Yan's login account and password to all the company's senior staff. They were allowed to use Super Computer Yan's resources freely. This was not because Aiken was generous. It was because their research projects were confidential and they could not send Super Computer Yan to handle. They also did not want to waste Super Computer Yan's resources. So, they allowed the senior staff to use Super Computer Yan's resources freely!

This was supposed to be one of Aiken's benefits, but now it had become a convenient channel for Shi Lei to hack into the supercomputer Yan!

Shi Lei browsed through the web server of Aicin. He thought for a while and decided to use Aicin's server. He was ready to hack into the supercomputer Yan!

Aiken's server is really good!

This company had five core servers that formed a server group. Each core server had a computing speed of 5.7 trillion Flops. The entire server group had a computing power of 6 trillion Flops per second, which was equivalent to a small supercomputer!

In 7551, the 055th supercomputer in the world only had a computing speed of 7.2 trillion Flops. In other words, Aiken's server group was one of the most advanced in the world!

After deciding to use Aicin's server, Shi Lei began to hack into Aicin. Since the server group of Love and Trust had reached the level of a small supercomputer, Shi Lei carefully controlled server No. 6 to scan the open ports of the other server group.

Shi Lei had already hacked into Aicin's web server. However, the web server was only used for the company's homepage and to store some unimportant documents. All the company's core information was stored in the server group formed by the five core servers!

The computing speed of server No. 6 was just barely satisfactory. Shi Lei could not help but feel anxious, but there was nothing he could do!

While waiting for the scanning results of server No. 6, Shi Lei fantasized about the super power of a broken laptop that could hack into a satellite. If only he had that kind of super power, how great would that be?

In hacking, hacking, obtaining, and controlling were all different things. For example, hacking into a server that stored confidential documents did not mean that one could obtain the secrets.

Within the same server, there were many different permissions settings. The confidential documents were also encrypted. Therefore, even if one obtained the confidential documents, one would not necessarily obtain the secrets. One would still need to crack the password.

As for controlling a server, that was the most difficult thing to do! To gain control of a server, especially a high level server, was extremely difficult!

Although the performance of a high level server was very good, and it was very satisfying to use. But at the same time, the security policies and firewall of the high level server were even more difficult to deal with. Moreover, there were security personnel on duty!

Although Shi Lei knew that there were many server systems and unannounced loopholes, he couldn't just do whatever he wanted and attack whoever he wanted. Every time a hacker tried to hack into a server, a network link would be established. After the network link was established, there would be data exchange. If the security personnel on duty at the high level server were to observe the data flow at all times, they would be able to detect any abnormalities. For example, the server could be likened to a full pool of water, and the network link could be likened to a water pipe that was connected to the outside. When the server was operating normally and there was no data exchange, it meant that the water pipe was not flowing out. If a hacker sneakily added a water pipe to leak water, the security personnel on duty would definitely notice the leak.

Server No. 6 slowly scanned Aicin and the server group's ports. Shi Lei had been waiting for a long time. After finding a suitable port, Shi Lei used Aicin's web server to simulate Aicin's internal communication and requested access to the server group.

After the server group received the request from the web server, the firewall of the server group did not block the request from the web server. Shi Lei used the normal request and successfully infiltrated the server group through an undisclosed vulnerability!

After entering the server group, Shi Lei did not act rashly. Instead, he started to investigate the firewall of the server group. If he did not take care of the firewall, the moment Shi Lei started to clear the authority group, the firewall would send out an alarm!

Shi Lei used server No. 6 to analyze the firewall, and at the same time, he investigated the firewall manually. Aicin's firewall was obviously not something that could be found on the market. It was a custom-made firewall system that was commissioned by a network security company.

Borrowing a saying from the hacker world, a free firewall has zero defense effectiveness!

After spending close to two hours, Shi Lei finally understood the basic situation of the firewall. Aicin's firewall was actually provided by Norton!

In his previous life, Shi Lei had specially researched Norton's firewalls. He was very familiar with all their products. Although Aicin's firewall was custom-made by Norton, its source code was also developed based on Norton's products.

Shi Lei was writing a malicious program in the server group. He was preparing to destroy the firewall!

The best way to destroy a firewall was to do what Shi Lei did. Find a loophole in the server's system, enter the server, and destroy the firewall from the inside.

After all, the firewall's external defense was very strong, but its internal defense was much weaker!

After 65 minutes, Shi Lei finished writing a malicious Trojan horse that targeted Norton's firewall. Then, he started to destroy the firewall from the inside. The custom-made Norton's firewall was still in Norton mode. The malicious Trojan horse written by Shi Lei started to destroy the firewall from the inside!

The firewall's function was gradually replaced by the malicious Trojan horse. The whole process was silent and did not attract the attention of the security personnel.

After the malicious Trojan horse destroyed Norton's firewall, it was unable to detect the firewall's signature code. Then, it started to self-destruct and erased itself from the server.

Shi Lei rested his hands on the keyboard with a triumphant smile on his face. He did not expect to destroy Norton's firewall so easily!

After typing a few lines of code on the keyboard, all the authorized users in Aicin's server group were listed on the screen of Shi Lei's computer.

On the surface, there were only three super authorized users in the server group. There were also more than ten users with different levels of authorization. Shi Lei continued to type the code carefully and inserted it into the server group's authorization system.

After a while, two more accounts appeared on the screen. The authorization of these two accounts was even higher than the three super authorized users!

"F * ck, they are as cunning as Stone Head. They like to hide the real super authorized users!" Shi Lei said with disdain.

Hiding the real super authorized users was a common tactic in high-grade servers. If a noob hacker hacked into a high-grade server and obtained the real super authorized users and started to create their own super authorized users, they would be exposed in an instant!

Shi Lei found the real super authorized users that Aicin had hidden. But he did not touch these two super authorized users and did not create his own super authorized users. Instead, he started to write the code to replace the original authorization system in the server group's system.

If he used the original authorization system in the server group's system to create a super authorized user, even if it was hidden. Once Aicin's super authorized users checked the server group's authorization system, the newly created super authorized users would be exposed. That would be equivalent to exposing the intrusion.

Therefore, Shi Lei needed to create a new authorization system to replace the original authorization system in the server group. In the new authorization system, the two hidden super authorized users would still have the highest authorization. But in reality, Shi Lei would create a higher level super authorized user and hide it in the system.

Because of the new authorization system, even if the two original super authorized users checked the server thoroughly, as long as they did not find out that the authorization system was replaced, they would not find out that Shi Lei was hiding the super authorized user. Under normal circumstances, the security personnel would not suspect that the authorization system was replaced.

This was because the task of replacing the system was definitely the hardest of the hardest. Only a world-class hacker like Shi Lei could do it!
