super wormhole

() When Yan Yuyao contacted his master, Yan Guo did not leave a trace and was on an annual vacation tour.

Not long ago, Yan Guo was promoted to the network security director of a certain bank, responsible for the security of the bank's online banking system.In the past year, he has washed his hands of the gold plate and no longer participates in online hacking activities.

After becoming a supervisor, there are more things to do in various aspects, and less purely technical research, but he is not out of touch with the circle. Those who do network security must keep up with technological trends.After listening to Yan Yuyao's story, he was even more shocked than Yan Yuyao, which was simply impossible.

From the perspective of Yan Yuyao's level, top experts are always so mysterious, mastering omnipotent techniques.But at the level where a wild goose leaves no trace, there is no mystery in hacking technology.All means, all methods are nothing more than those types. The so-called cleverness is nothing more than prescribing the right medicine, knowing the status of the target computer, and making targeted deployments.

The protection software used by the apprentice was developed by himself, incorporating his own understanding of network security, and it was easily broken through by someone. Thinking about it made him feel terrified.

The security system of his own bank was also developed with this idea, but it was more powerful. If that person wanted to hack into the bank, the chance of success might be quite high.Yan Guo did not leave a trace broke out in a cold sweat, and immediately ended the tour. He felt that it was necessary to meet the poster of "free world" for a while.

As soon as Yan Guo did not leave a trace and rushed back to Donghai City, the phone rang. He looked at the screen and saw that it was his friend Gu Ye Piao Ling calling.

There are only a few top people in this circle. He and Gu Ye Piao Ling met a few years ago and became close friends.Gu Ye Piao Ling is the vice president of the technical department of a large domestic online shopping platform, and is responsible for network security full-time.

"Old Goose, have you heard about the guy from Zi You Tiandi? What do you think?" Since they spend most of their time communicating online, they are also used to mentioning their online IDs when they talk on the phone.

"Yezi, I was just about to call you. To be honest, I'm quite worried. If this person wants to hack into the bank, he will probably succeed."

"Similarly, if he wants to hack into the shopping platform, I really have no choice. He should have mastered one of the deadliest loopholes in the Cao operating system that has not been made public."

Yan Guobu Leaving No Trace took a deep breath and said, "Let's join forces, try?"

"That's what I meant."

……

That night, Bai Yunxiao rushed to Yan Yuyao's studio, and saw that besides Yan Yuyao, there were two men in their thirties.

Both of them showed the meaning of corporate executives in terms of their dress and temperament.

Yan Yuyao introduced with a smile: "Xiaobai, this is my master."

"Ah!" Bai Yun jumped up with a smile, and shook his right hand violently with both hands, "It turns out to be the God of Wild Goose, and his name is really impressive."

Goose Passes Without Leaving Traces chuckled: "I've seen your Zhishu posts, and your level has improved very quickly, which is about the same as ours. But you are still very young, and there is still a lot of room for improvement."

Yan Yuyao said again: "This is Senior Gu Ye Piao Ling."

"Ah, another great god!" Bai Yunxiao was extremely shocked, "I played against God Ye last year, and I was very impressed."

Gu Ye Piaoling smiled and said: "If we fight again, I'm not sure I'll win you. You're making rapid progress, and you'll be a formidable future."

If the people of "Freedom World" knew that the four of them had gathered together, it would definitely cause a huge commotion.

Bai Yun looked at Yan Yuyao suspiciously with a smile, and Yan Yuyao said, "Master and God Ye came here together to meet the expert recruited on the forum."

Bai Yunxiao was very excited immediately, the three most powerful gods in his mind were about to start a battle to the top.I am fortunate enough to be on the sidelines.However, why did Yan Shen and Ye Shen intend to join forces, two against one, this is a bit unfair.

Just when Bai Yunxiao was stunned, Gu Ye Piao Ling and Yan Guo Bu Leu Trace had already started to act. They turned on their laptops and connected to the network of the studio.

"Don't be stunned, we can also wave the flag and shout beside us." Misty Rain said with a smile.

Bai Yunxiao came back to his senses, started to turn on the laptop he brought, and connected to the Internet.There are several servers in Yan Yuyao's studio, and the network has an exclusive 100m bandwidth for optical fiber access.

The four of them were all sitting in front of the computer, and the room was very quiet, except for the slight sound of the computer cooling fan and the hard disk spinning, there were only the clicking of the keyboard and the click of the mouse.Details determine success or failure, and the habits of details that have been developed over the years will not change. They meticulously debugged the computer, opened various hacking software, disguised IP, and then carefully scanned the target through multiple springboards.

Gu Ye Piao Ling frowned and said, "All the ports that should be opened normally are open, and they look completely undefended. How do you plan to attack, Old Yan?" Every opening is a trap.

Yan Guo said without leaving a trace: "Yezi, you attack head-on to attract the opponent's attention. The three of us sneak in in a roundabout way. Are you ready? Okay, let's start."

Gu Ye Piaoling's fingers danced on the keyboard, as if she was playing the piano, so fast that her eyes couldn't see clearly.With his operation, countless zombie computers sent massive data requests.This flood of data floods the target server, slowing down the server.

At this time, Li Hao was studying alien technology in the newly bought house after practicing the Force.Zhinao suddenly issued a warning: "It has been detected that the remote server has been attacked. The attack is more violent than ever, and three users are trying to elevate their privileges at the same time."

Li Hao said with a smile: "It seems that some masters have come out, so I will play with them."

Gu Ye Piao Ling looked at the feedback information, the server did not occupy much bandwidth, the network was congested, and normal users could no longer access it.And the performance of the server is not very good, it is estimated that there may be a crash in the near future.

But a strange thing happened, the server speed was only slowed down for about [-] seconds, and then returned to normal.The server did not know what method was used, and all these junk data were filtered out.

What was even more surprising was that Lonely Leaf Piaoling found that the number of zombie computers he could call decreased rapidly, and those controlled computers kicked himself away and cut off the connection automatically.When I tried to connect again, I found that the original back door was gone, and the zombie computer had returned to normal and was no longer under my control.

In just a few seconds, thousands of zombie computers were all out of their control, and none of them could be connected through the back door again.

Gu Ye Piaoling stared at all this in a daze, "God, tell me what's going on."

At this time, Yan Guo did not leave a trace and yelled: "Damn!" The protection software on my computer popped up a blood-red text: "Warning, the computer is under attack. Warning, the computer is being invaded. Warning, external users are Elevate privileges. Warning, the external user has obtained administrator privileges."

These words flashed one sentence after another, without any pause at all. When the geese passed by without leaving a trace, he came back to his senses, and his hands were beating rapidly on the keyboard. He wanted to delete that user, but found that his authority had been reduced. Delete the other party's authority.

"This...how is this possible?" Yan Guo Leave No Trace felt incredible.

Gu Ye Piaoling said in astonishment: "The other party used a supercomputer. I have so many zombie computers, and they all returned to normal at once. How much processing power is required to do this? Old Yan, analyze it, what level of supercomputer is this?" Computer? The top Tianhe series supercomputers in our country are nothing more than that. How can he control supercomputers of this level?"

The geese passed without leaving a trace and said in surprise: "He is still tracking me at the same time. I have used seven springboards. Some of the springboards in the middle were developed by du li of the cao operating system. How did he do this? Could it be that he can really control The top supercomputers in the world?"

Gu Ye Piaoling was shocked and said: "Impossible, even if he really controls the top few supercomputers, he can't complete such a large data processing in an instant. You must know that I have a terrifying number of zombie computers. Unless he is in During the period just now, let the supercomputer serve him completely. But is it possible? If he does this, he will definitely be found. Supercomputer, there must be technicians on duty, such an abnormal situation, Even the blind can see it."
