Reborn Ace Hack

After Gu Lang's countdown ended, almost everyone present held their breath and stared at the traffic monitoring software running on the computer screen. Although the network traffic fluctuated, the curve was still green. It was obvious that no traffic occurred.

Rapid increase.

"Is Thunder kidding everyone?" A staff member whispered as he did not see the expected surge in traffic.

"Haha, maybe it's a delay issue, please wait patiently for a few more minutes," Gu Lang said.

The time on the computer had reached 04:00 in the morning, and there was still no movement. This time, even Tang Xinyu couldn't hold himself back and said, "Isn't it really Thunder who made an international joke?"

"Haha, the consequence of deceiving almost all hackers is to become a street rat. Such a joke is not fun at all." Gu Lang said with a calm smile.

"The traffic has increased!" At this moment, a staff suddenly shouted, attracting all the attention. Sure enough, the traffic curve, which had been ups and downs, but the overall trend was very stable, suddenly turned almost ninety degrees.

It rose and rushed to an extremely high peak in a few seconds.

Didi, the computer running the network monitoring software started to alarm. At the same time, the upward trend was curbed to a certain extent. The overall trend remained stable at a very high position. The traffic curve was no longer a harmonious green, but turned into a striking orange.

red.

"Xuan Nie Firewall has started working." Gu Lang called up the firewall logs and saw that the logs were growing at a very high speed. It was obvious that the firewall had begun to use its own strategies to adjust network traffic.

"The attack is so fierce!" Tang Xinyu sighed sincerely as he looked at such a high curve.

"Haha, it seems that the Xuannie Firewall is still very strong. If it were a normal firewall, it would probably have collapsed under such a large amount of concurrent access traffic." Gu Lang said with a smile. Obviously, he was not satisfied with the current situation of the Xuannie Firewall.

Very satisfied with the performance.

This high level of traffic lasted for about five minutes. Although the computer where the traffic monitoring software was installed kept beeping alarms, the server was able to withstand it stably with the help of Xuannie Firewall.

However, this high and stable situation was broken by another stream of traffic that suddenly joined in five minutes later. On the network traffic monitoring software, the traffic curve rose again, and the frequency of the computer's beeping alarms became more intensive, one sound louder than the other.

The urgent sound of the alarm made the already tense atmosphere even more tense.

"Damn, the beeping is really annoying. You should have removed the alarm sound at that time." Gu Lang cursed and said.

"The traffic is stable again, holy shit, it's about to reach the top!" Tang Xinyu's words focused everyone's attention on the computer. A bright red curve floated high at the top of the chart, which was shocking.

At this time, no one was interested in paying attention to the beeping alarm.

"If another wave of traffic comes in, the firewall will not be able to support it," Gu Lang said.

Just when they were worried about whether the firewall could continue, the traffic curve suddenly began to slide downward, and soon changed from bright red to orange, and then to green.

"The firewall is still working, Xinyu, come and take a look at the logs." Gu Lang pulled out the system logs again and pointed at the logs that were scrolling rapidly.

"So many IP addresses have been blocked by the firewall. It seems that the firewall is really working hard." Tang Xinyu looked at the log and said.

"Yes, the firewall has obviously found that these surges in network service requests are all machine patterns, or even repeated requests. After analyzing these requests, it has made a judgment that these requests are by no means normal service requests, but

For human-controlled attacks from the Internet, it has now done a very simple process, that is, recording and blocking such IP addresses, and then discarding the sent data packets without any processing, thus reducing the processing pressure on the server.

." Gu Lang said.

"Then what happens if, like just now, the traffic increases a little and exceeds the traffic limit of the network itself?" An employee couldn't help but asked out of curiosity.

"Our firewall has done its best to prevent this situation from happening. It is like a policeman, firmly controlling the door of network data entering and exiting the server and a section of the road not far from the door. But no matter how smart the firewall is,

After all, it is just a program. Compared with real people, it is still very different. In addition, it also has its own processing limit. If the network traffic increases too fast and exceeds the instantaneous processing limit of the firewall, then according to the settings I set in advance

According to the rules, the firewall will automatically logically disconnect the server's network to prevent the server from crashing due to massive data access." Gu Lang seemed to be happy to explain some knowledge to others, so when the employee asked him, he didn't

Feeling impatient, I explained it to the employee in detail.

As if to verify Gu Lang's explanation, just as he finished speaking, the network traffic surged again. In less than three seconds, it reached the maximum value that the network could bear. However, this time the traffic did not increase as much as

It stayed at the highest value like last time, stabilized, but continued to rise, and the red line soon exceeded the limit.

Didi, the computer made a sharp beeping sound, and then the network traffic suddenly dropped to zero, and the dazzling red traffic curve also turned gray.

"Haha, Gu Lang, you have the potential to be a prophet." Tang Xinyu laughed and said.

When several employees saw that Tang Xinyu did not become depressed because of the scene in front of them, but instead started joking with Gu Lang, their originally nervous mood became lighter and they all burst out laughing.

"Okay, I'll leave the next thing to you. Let's find a place where we can go and see if the forums are already filled with gongs, drums, cannons and music." Tang Xinyu said, and after speaking, he took a few people with him.

The staff left the network monitoring room and went to find another place, leaving Gu Lang alone busy in the monitoring room.

…………

If, as Tang Xinyu expected, when Xuannie Firewall proactively cut off the network connection and blocked all plots, Thunder immediately posted the news of successful DDoS attack in several forums and chat rooms. The forum

In the chat room, it became very lively and full of joy. A large number of people who participated in the attack posted messages to express their congratulations. Some people even started to shout that Xuannie Firewall was nothing more than that and vulnerable. Gu Lang was asked to prepare one hundred thousand yuan.

They will soon completely destroy the Xuannie Firewall and obtain the document that marks the victory of the challenge.

Several employees of the company looked at the lively scene in the forum and felt a little anxious. They wanted to post a post to defend the company, but Tang Xinyu strictly prohibited it. Although several employees did not understand Tang Xinyu's order, they did not understand it.

Still he carried it out very honestly, browsing the information on the Internet and waiting for Gu Lang's arrival.

Fortunately, Gu Lang didn't keep them waiting for long. After about twenty minutes, he came over from the network monitoring room, called several employees together, and said, "I will post on several forums later.

Then follow my instructions and follow up. As long as you do it properly, we can turn this matter into a good thing."

After giving the instructions, he said to Tang Xinyu: "Let those people make a fuss for a while. By two o'clock in the morning, they will be almost noisy. At that time, it will be our turn to speak. Xinyu, you can contact Sa now

Sister."
