In the face of possible emergencies, Zhou Shuo did not have the previous nervousness. I just slipped my mind and sighed secretly, thinking that my subordinates had finally learned to knock on the door anyway......

"Please come in." Yu Qiong glanced at Zhou Shuo, and then shouted loudly.

"President Zhou, General Manager Yu." The visitor pushed open the door and took a breath, but he didn't seem to be flustered.

"What's the matter?" Zhou Shuo nodded and asked with a frown.

"The system resource occupancy has suddenly increased significantly, and Manager Shao is not sure of his idea, so I would like you to judge it." The man paused, swallowed and said, "Let's see if it's a hack." ”

"Hacking?" Zhou Shuo also stood up a little nervously, he was also a little numb. He can still write programs, but the hacking technique is a blind eye.

"Not necessarily, it's just that Manager Shao hopes you can provide some advice."

"Alright, let's go." Zhou Shuo took the lead and walked out the door.

Zhou Shuo went out and turned around, trotted two steps into the machine room, and couldn't help but be stunned.

Unlike the panicked scene he expected, although the atmosphere was a little tense, no one was panicking or scrambling.

Shao Shiming calmly dispatched his programmers, increased the number of servers opened, activated the hardware firewall, and filtered invalid IP connection requests.

"How's it going?" Zhou Shuo stood beside Shao Shiming and looked at the computer screen in front of him, which was the operation of the entire six-ear server array.

"The network request has reached 500M/s, and the system resource occupancy rate is also rising, and 15 servers have been opened so far." Shao Shiming is familiar with the situation. It relieved Zhou Shuo a lot.

The company's operation is not afraid of a situation, but the person in charge is afraid of panicking in the face of the situation. Shao Shiming's performance. At least it shows that he is fully capable of doing a good job in the position of the chief technical officer of Six Ears Software Company.

"Was it a hacker?" Zhou Shuo looked around and asked in a low voice.

"Not really. In fact, the vast majority are valid requests. Shao Shiming shook his head, pointed to a curve on the screen that suddenly raised his head and said: "However, the load of the system has increased rapidly, almost five times the speed before, and many of them are connected by high-speed lines." ”

"Bring up the request IP and show me." Zhou Shuo had a faint guess in his heart that needed to be verified.

Shao Shiming tapped twice on the keyboard, and the IP being accessed was displayed.

"Filter out connections below 64Kbps."

After Zhou Shuo's request was realized, the remaining connection IPs were indeed less than the vast majority. However, these connections are only a fraction of the number of connections that used to be made, but they take up 80% of the network bandwidth.

"What's going on with these high-speed access?" Shao Shiming asked strangely.

"Write down their IP addresses, and I think I know what's going on." Zhou Shuo said confidently.

Wait for Shao Shiming to copy all the IP accessed by him. Zhou Shuo then commanded: "Now run the Archie software, do you have it here?" It's the software that can search the software archive within the world. ”

Shao Shiming nodded, and said as a matter of course: "Of course there is, this software is very good, and there are many excellent resources in the list of FTP servers provided." A lot of the software installed on this computer is downloaded through it. ”

Zhou Shuo patted him on the back and said with a smile: "That's right, let's take a look at its FTP server list now." ”

"This ...... How so? Shao Shiming looked at the list of FTP servers searched by the Archie software for some reason. When I checked it with the IP address I copied, I found a lot of duplicate server addresses.

"It's definitely the FTP server that is picking up our software." Zhou Shuo smiled proudly: "You see that there are not only servers in the United States, but also many IPs from Europe, India and Japan, don't forget that we have not only made English versions." Various international versions are freely available during the installation process. However, due to the Internet interface and latency issues, downloading software in other countries will definitely be much slower. After the FTP server collects it, it is available for local people to download. It's going to be faster. ”

"Wait a minute!" Zhou Shuo stopped Shao Shiming from closing the IP list, pointed to an address and said, "Check this address." I feel like something is wrong with it. ”

"It's ......"

"Hey, brothers, keep it up!" Catherine shook her fist hard. Boosting everyone's morale: "As long as you can get the server program of this software, Mr. Mark promises a million dollars!" ”

"Oh, oh, oh—" As soon as her words fell, a cheering shout suddenly sounded around her.

In a spacious basement, more than a dozen computers are arranged in two rows opposite each other. All kinds of networks and electronic devices are constantly flashing as data and current pass by.

Catherine is the queen of the land of electronics and data, and she walks between wires and network cables, inspecting the progress of her work.

These ordinary people in ordinary life have become thieves in the Internet world at this moment. As long as they raise their butcher knives, there is little information they can't steal and enemies they can't deal with.

"Okay, now the other party must have let his guard down. Next I want you to activate all the broilers and launch a flood of DDos attacks! The time had come, and Catherine decisively gave the order to attack.

"It's a hacker!" Shao Shiming typed on the keyboard and tested the connection to several hosts that had turned on the service. Reminders of connection timeouts are constantly refreshing the bottom of the screen.

"Increase the number of servers!" Zhou Shuo ordered decisively.

"All servers are online!" Shao Shiming hurriedly greeted, and the programmers sat down in front of the server they were responsible for according to the plan, and began to operate continuously.

"Five sets of servers are starting to go live!"

"Three sets of servers are online!"

On the other side, Catherine began to spin in circles anxiously. Although the attack went well, a sense of foreboding began to loom over her.

"DDos attacks are failing!" The hacker who was operating shouted in surprise.

"It may be that the service response time has been shortened, don't be afraid, it's just a technical adjustment! Continue to increase the intensity of your attacks and mobilize more broilers! Catherine suppressed the discomfort in her heart and calmly ordered.

In the hacker group, someone suddenly shouted: "It's completely ineffective, and there are fewer and fewer IPs that delay response." It's a really weird thing, are we attacking NASA's supercomputer? ”

"Don't talk nonsense, hurry up!" Catherine frowned and reprimanded.

Shao Shiming wiped the fine hair on his forehead, and the sudden DDos attack really startled him. However, when the rest of the servers in the computer room were all online, the attack was finally blocked.

The so-called DDos attack refers to a hacker attack method developed from DoS. Dos is the abbreviation of DenialofService, which means denial-of-service attack. By using reasonable service requests, it occupies too many service resources, so that legitimate users cannot get a response from the service, or the target server causes errors such as crashes and memory overflows.

In the early days of Dos attacks, a one-to-one approach was generally adopted. When the target has a low CPU speed, small memory, or low network bandwidth, its effect is more obvious. In the early days of the Internet, Dos attacks were a common tactic. With the development of computer and network technology, the opening of various high-performance computers and gigabit optical fiber networks, Dos attacks are not enough.

DDos is an upgraded version of Dos, which uses broilers to coordinate more resources and launch a tidal wave of attacks at the same time. In 1995, this technique was still very advanced.

"How's the system resource usage?" Zhou Shuo didn't let go of his worries, although he withstood this wave of attacks, but who knows what tricks the other party will make next?

"The server load is 20%, and the network bandwidth utilization rate is 2G/s." Shao Shiming skillfully reported the data.

Zhou Shuo did the math for a moment, and couldn't help but be startled and said, "Doesn't this mean that at least 600,000 users are connecting to our server?" Even excluding users with normal connections, there are always 300,000 broilers. ”

"If it weren't for the fact that our system is too powerful, we might have planted it here." Shao Shiming said with palpitations.

In the basement, Catherine and her men had been quiet for a long time. On the monitor, the feedback that the connection is working is constantly displayed, but it is not at all pleasant.

"Head, what to do? Our broilers are all online, but all of a sudden it's ......"

The hackers, who were at a loss, looked at Catherine stupidly. They have never experienced this situation, and the tide attack of 300,000 broilers has not even set off a wave from the other party. It seems that the other side is just a little serious, and digests the attack with a full burp.

Catherine's face turned pale, and she took out her mobile phone and dialed: "Mr. Mark, I'm very sorry that the attack failed. ”

"No, it's all your fault, the information you provided is shit at all! If I had known that the other party had a supercomputer as a server, I wouldn't have taken on this task at all! ”

"Don't have a supercomputer?" Catherine didn't believe it at all, and roared back loudly: "Then you explain, how they withstood the DDos attack of 300,000 broilers!" ”

Mark. Anderson didn't want to waste any more time and hung up. He thought for a moment, picked up the phone again, and dialed a number.

"I'm Mark, please ask Anthony, an engineer from the Technical Department, to come to my office."

"Yes, now."

Mark. Anderson hung up the phone and looked out of the floor-to-ceiling window of his office. The huge logo of "Netscape" is slowly standing on the roof of the company by a crane. (To be continued......)
