At the moment when a person is about to succeed, he will give him a hard blow, causing fear and loss to appear on his face, which will make him particularly painful and have a deep memory.

The brothers in the field have been comfortable for six or seven days, so they should move. They monitor Xuan Qi's online industry through the Internet, and continue to use legend as a breakthrough. When Xuan Qi starts to upgrade the server, they suddenly take action and play with the other party in applause.

In front of the computer of the development department, there were technicians sitting in a row, looking at the increasing extreme bars, joy flashed across their faces. After the server leaked the secret, they were all a little embarrassed and kept trying to plug the loopholes. As Hyun-ki and Park Jung-tae came back, they took the mature password verification system and repaired the loopholes.

In the past few days, the technicians on the Peninsula have shown their super combat power. They have used three days to complete the kernel upgrade, and used three days to conduct stress tests. After confirming that the kernel is correct, they will only be subject to Xuanqi to test. After all, they will be submitted to Xuanqi for testing. They will wait for confirmation that there is no accident before they can start upgrading the server.

Ninety-five percent, Ninety-six percent, Ninety-nine percent, Ninety-nine percent, Ninety-nine:9, Ninety-nine:99…

The programmers all had smiles on their faces, and they were still only 0.01% successful. The data strips that were originally rolling suddenly stopped, the server became a little slow, and only 20% of CH used suddenly soared to 100%, and even the memory soared straight up.

"What's wrong? Is it the server hardware error?" Jin Sanshun immediately ran forward to check. When he heard the fan spinning wildly due to overload pressure, Jin Sanshun immediately conducted a debugging and checking. However, he found that the hardware was normal and there was no error.

Park Jung-tae looked at the sudden increase in visits and said in surprise: "Why are there so many network accesses suddenly?" After being stunned, he exclaimed in a low voice: "Is this a DDP attack?"

With the development of computer and network technology, computer processing capabilities have grown rapidly, memory has increased greatly, and gigabit-level networks have also emerged, which has increased the difficulty of attacks, and the target's digestion ability of malicious attack packets has been greatly enhanced. If the attack software can send UU0 attack packets per second, the host and network bandwidth can handle 10 and UU0 attack packets per second, so that the attack will not have any effect.

At this time, the distributed denial of service attack method DDP came into being. The principle of attack is very simple. If the processing power of computers and networks is increased by 10 times and attacking with one attack machine can no longer work, what if the attacker uses 10 attack machines to attack at the same time? What if 100 units are used? DD is to use more broilers to launch an attack and attack victims at a larger scale than before.

A network with wide connection at high speed brings convenience to everyone and creates extremely favorable conditions for DDP attacks. In the era of low-speed networks, when hackers occupy puppet machines for attacks, machines that are close to the target network will always be given priority, because there are fewer hops through the router and the effect is good. The connection between telecommunications bones and nodes is at the G level, which can be achieved between large cities, which allows attacks to be initiated from farther places or other cities. The attacker's puppet machine location can be distributed in a larger range and is more flexible in choosing.

After confirming that it was a DDP attack, most technicians were helpless. They were just technicians who developed and compiled the game and were unable to deal with hacker attacks.

Park Jung-tae immediately pushed open the door of Hyun-che’s office and said breathlessly and frightenedly: “The server was attacked by DDP and the server could not be updated normally.”

Xuan Qi, who had already noticed that the server was suffering from DDP attack, waved his hand and said, "I understand." Then he typed a few commands on the keyboard with his palm, and immediately diverted the attack like a tide. The CPHL, which was running 100%, dropped again, reaching 60% and between 80%.

Park Jung-tae, who was stunned, heard the cheers of programmers outside the house, and Kim Sansun was cheering: "The load is falling, it is falling." Park Jung-tae looked at Hyun-ki and asked: "Did you do this?"

Xuan Qi nodded. This was just the first round of fight. Xuan Qi was screening in numerous data streams. Only by finding the mastermind behind the scenes and giving it a ruthlessness can this attack like a tide.

Park Jung-tae squeezed his eyes and found that he could not see through Hyun-ki for a moment. This master-level figure in the Internet layout actually had such skills. Park Jung-tae silently closed the door, not daring to disturb Hyun-ki. At the same time, a trace of flame rose in his heart. Should he do something?

Brother Tianma watched the DD attack being diverted, and a smile flashed across the corner of his mouth. The island hacker who likes to catch broilers the most has a large number of broilers in his hands, all attacking an IP address. Can diversion really solve the problem? Erro Tanma whispered: "Sanlang continues to attack, DY is responsible for sweeping the tail, I'll go and see the powerful firewall."

In the small hut, there were twelve computers in total. Because the server upgrade was hasty, the three people seemed a little hasty when attacking. After fighting with Xuan Qi, they actually forgot to close the intranet of Mask Island.

Waves of DDP attacks came like waves, and wave after wave hitting the Norton firewall. Among the rows of rapidly flowing data, Xuan Qi was looking for information that was useful to him. As the data continued to flush, a smile appeared on the corner of Xuan Qi's mouth. There should be two enemies, one of which was DY.

Just as Xuan Qi was about to track it backwards, the small speaker in the laptop suddenly rang twice, as if reporting a fault. Xuan Qi's face was shocked and went back to investigate another log. As a result, he saw a small section of abnormal data on it, and someone was cracking the firewall of the supercomputer.

"The enemy changed from two to three" Xuan Qi gritted his teeth: "In addition to the two who came D, they are all super experts."

His fingers quickly typing on the keyboard. With the continuous hits, the background programs of the notebook suddenly increased. Xuan Qi used both of his heart, helping the server to divert the DDP attack, and on the other hand, he began to catch up with this Ip. The original value in the notebook was only ten percent or even less, and it began to increase up little by little.

With Xuan Qi, who surpasses this era and has the vision of this era, the invasion speed is extremely fast. Others need to enter a large string of instructions to complete the analysis of a data segment, and the Xuan Qi shortened it into a few tiny letters. After the letters were pressed and entered, the instructions ran wildly. Xuan Qi tracked down Erro Tanama's first springboard, and also touched the alarm set by Erro Tanama.

A sudden sirens came from the narrow room. Tianma Erlang suddenly became stunned and shouted at Sanlang: "Come and help me sweep it out quickly, someone has targeted me."

Saburo and Erlang had already been in a relationship, so they naturally understood what to do. They quickly switched the program to help Erlang sweep it out, and said to DY: "You continue to carry out DDP attacks, don't stop for a moment."

After the brothers in the field merged, they were equivalent to a senior hacker. Saburo helped Erlang to sweep his tail, while Erlang took Xuan Qi around in circles, traveling from Latin America to Antarctica. The IP address was switched suddenly and continuously, and the broilers they caught were abandoned continuously.

After Xuan Qi chased three springboards, he felt that the pressure increased greatly. Originally, Erlang would leave more obvious traces, but the traces left less and less as he continued to chase. This made Xuan Qi feel a little more pressure, and the opponent seemed to be no longer one, but two spirals.

When a hacker fights on the Internet, it is not necessary to win if there are too many people. Cyber ​​offensive and defensive wars, especially server attacks and tracking, and even anti-finals, a powerful hacker can often have the final result.

If two hackers who are not in a tacit understanding of each other, they will work together to deal with a super hacker. The network delay and the inability to communicate with each other will be a one plus one less than two effect. The original cooperation will become a flaw and a flaw to be attacked by others.

Because the brothers in the field are twins, and they use the same network and have the same computer, they have already had the same intentions, so there is no such thing as others worry about it. Instead, they are like a monster with two hands and four hands, operating the keyboard.

After tracing, a trace of bitterness appeared on the corner of Xuan Qi's mouth, which was a bit difficult to deal with. The other party was very agile, responded quickly, and had tacit understanding and almost skillful cooperation. His hand speed was fast, but there was no mistake. He had a series of offensive and defense cleaning, and he was about to break through his tracking.

Xuan Qi's experience was insufficient after all, and he was helpless in the face of this situation. He suddenly made some letters wrong and the macro command could not be generated. The IP that had been tracked suddenly disappeared, as if he had never appeared before.

"Tsk" Xuan Qi was very upset, narrowing his eyes slightly at the letter on the laptop keyboard. He couldn't figure out why he made such a low-level mistake. Why did he enter the wrong input after repeated trials?

I reached out and pinched the key cap of the key press. The originally elastic key cap was completely retracted into the keyboard. The film underneath was continuously hit and had aged.

Unfortunately, Xuan Qi pulled a keyboard from the side, connected it to the laptop, and stared at the screen. The DDP attack continued, and the other party would definitely come. If the preparation was not sufficient this time, then the next time would definitely be several times more cruel than this time. Xuan Qi believed that the other party would definitely come again.
Chapter completed!
