Chapter 24: Become famous in one battle
Chapter 24 Become famous in one battle
Everyone looked back and saw that the man who came in had a tall figure and was wearing a slightly wrinkled white shirt, as if he had just come from somewhere else.
When Bai Ye saw it, he wanted to rush forward immediately, "Brother Qi, you're finally here." He didn't notice a strange flash in Yunsu's eyes next to him.
“Thank you for your hard work, leave it to me.” The man said to Bai Ye.
Liehuo walked up and said, "Lan, I thought you weren't coming, but what happens next is exciting." Then he said, "Since you're here, let's not talk nonsense. You decide the second game. What's the competition?" ?”
The people in YN all looked like they were sure of winning. They were sure to win in anything.
Lan pondered for a while and then said: "Reverse, reverse engineering."
Reverse, reverse engineering. It is a common question type in CTF competitions. Find a software, but usually there is no source code of the software. Use tools to decompile or disassemble the software to understand the internal logic and principles of the software, find out the algorithm related to flag calculation and crack it. , get the flag.
"Okay." Liehuo agreed happily. He was preparing to face Lan in the second game. In the far corner, a man who seemed to have no presence spoke.
“Boss, let me do this round.” The man looks ordinary, and no one walking on the street would believe that he is a computer expert who is famous online.
After finishing speaking, everyone started talking about who had joined YN. After a while, the crowd dispersed, and a man slowly walked out. He was wrapped in red clothes and his face was hidden in the hood.
As expected, Lie Huo looked at them again and said, "In the third round, our side will be played by Hong Yi. You can decide the topic. Which one of you will be on it?" He said it very easily. He was obviously very relieved about Hong Yi's strength and felt that There is nothing to fear from these two people.
Lan's movements were very fast, and all the processes were smooth and smooth, as if he was confident. His long fingers were dazzling. Twenty minutes passed, and after he typed the last key, Bai Ye cheered loudly, and Kou Zi opposite knew that I lost, and lost again at the hands of this person.
“Okay, then you come.” Lihuo obviously understood Kou Zi’s thoughts. He wanted to defeat Lan and clear his name.
"Yeah! I knew, Brother Qi, you would definitely win!" Bai Ye excitedly high-fived Lan.
A smile appeared at the corner of his mouth, and Kou Zi across from him happened to raise his head and glanced at him, feeling a chill in his heart. It was this smile again. He knew he shouldn't pay attention to his opponent, but he just couldn't control it.
"Yes, you won the second game." Liehuo's face was a little ugly, but he was not unable to lose, and with so many people watching, he did not dare to say otherwise. Suddenly he thought that he had arranged a backup plan, and he felt in his heart A little relieved.
Lan looked at Lie Huo, "We won the second round, right?"
Software reversal requires proficiency in multiple programming languages. Obviously those who can sit here are the best. Then they analyze and understand the binary files, and then use a variety of decompilation and disassembly reverse tools to find the relevant algorithms step by step and then crack them. .
No one knows the man's true identity. Because he always wears red clothes, everyone calls him Hong Yi. Hong Yi has both fame and strength, and he is the top three players in the country.
He walked to Liehuo and nodded slightly to greet everyone.
He stood in the center of the hall, looked around at everyone, and said: "The second game is over. Here, I, Liehuo, would like to disturb everyone first. I invite everyone here today. In addition to witnessing the game, I also want to announce a happy event, that is, there is Seniors have joined our YN, welcome everyone!" After that, he took the lead in applauding.
The whole place was silent for three seconds, and then the whole place was in an uproar, like a frying pan touching water. How could it be him!
Yunsu remembered that this was the man Bai Ye told her about the man who led many domestic hackers to fight against country A three years ago.
Bai Ye gasped. He and Lan looked at each other and understood the meaning in each other's eyes. No wonder, he said that although they had problems with YN, they would not bother to hold a special competition. , and inviting so many experts to watch the game is a bit too arrogant. It turns out that it is to announce the news that Hongyi has joined YN. This is to use them to establish their authority!
Thinking of the next third game, Bai Ye and Lan both had a bad feeling in their hearts. It wouldn't be the case. . . . . .
"Whoever comes, I'm in a hurry." Lan said without any politeness.
Calming his mind, he began to carefully complete the movements of his men.
Everyone present is a master among masters. It can be said that half of the Chinese hacker community is here tonight. The questions are naturally not of an ordinary level. As soon as Lan got it, he felt it was a bit tricky, but it was still within his ability. .
This is YN's third son, codenamed Kou Zi. He once fought against Lan and lost, and he has always been grudges about it. Today he is here just for Lan, so of course he will take the initiative to petition to play in this round.
Looking at him with eyes that seemed to be ridiculing, Bai Ye felt a chill in his heart, even his red clothes came out, how could this compare? Lan rubbed the knuckle of his index finger with his right thumb, which was how he was thinking.
In the second round, both sides were ready. The questions were provided by a hacker on site, and the laptop he brought with him happened to have the questions they needed.
"What are you afraid of? I'm still here." A slightly hoarse voice sounded in Bai Ye's ears.
Bai Ye's eyes lit up, "Master, why did I forget you? You must be able to do it."
"Brother Qi, this is the big guy who helped us before, my master, who I told you." The situation was urgent just now, and Bai Ye forgot to introduce Yunsu to others. Lan was startled. Is this the master Bai Ye often mentioned? A little too young, he looks like he is eighteen or nineteen years old at most, he is still a teenager.
Yunsu's expression could not be seen clearly under the mask, so she said, "I'll do the third game."
Lan persuaded her: "This is a matter between us, you don't need to get involved." Thinking that he was Bai Ye's master, he used the honorific title, although the boy in front of him looked younger than him.
“It doesn’t matter, it’s just for fun.”
Lan smiled bitterly in his heart. Who could say that it was just for fun when facing Hongyi?
"It doesn't matter, Brother Qi, just let my master come. I believe in her." Bai Ye was very sure.
"What, have we discussed it? If not, I can give you some more time." Liehuo looked at them with a smile.
“I’ll do it.” Before Lan could react, Yunsu walked out and all the eyes of the audience focused on her.
Liehuo frowned, "Who are you?" Only then did he notice her.
"My surname is Su, and I am their... non-staff member." Yunsu said casually.
“You really let him go to war.”
“Yeah.” This was the point, Lan had no choice but to agree.
Lie Huo sneered in his heart. If Lan came on the stage, Hong Yi might have a headache, but if he appeared out of nowhere, were he prepared to break the rules?
“How to compare?”
Yunsu looked at Hongyi. She was a little interested. "I heard that you are very good at offensive and defensive battles, so let's play something simple. Whoever can break into the opponent's computer first will win. How about that?"
The people in YN look weird. Do they want to die so much? Everyone in the audience also laughed at Yunsu's overestimation of his abilities.
“Where did this come from? It’s so shameless!”
“Playing offense and defense with Hongyi, you are still young after all, tsk tsk tsk.”
"Su? I've never heard of it. I've seen a good show."
Hong Yi looked at her and said, "Okay." His voice was low and magnetic.
At the beginning of the decisive round, Yunsu and Hongyi sat opposite each other, their hands flying. Hongyi's hands seemed to have not seen the light for a long time, showing a cold and silent whiteness. Yunsu issued instructions one after another, and his fingers were as white as green onions. Turning like a butterfly.
The computers of both of them are in the same local area network. It is easy to find the other party's computer. The competition is a confrontation between the two sides. Whoever can't withstand it first will break in first.
The movements on both sides were displayed on the big screen. The more people watched, the more shocked they became. This Su was not at all inferior to Hong Yi, and seemed to be about to capture him. Hong Yi's heart became heavier and heavier. The person opposite him was definitely like him. The most difficult opponent I have encountered in many years, bar none!
His palms were slightly sweaty, but his movements were not messy at all, and lines of code were quickly generated.
Five minutes later, Yunsu lost interest in playing with him anymore. With three taps and two taps, his fingers almost danced into afterimages. With lightning speed, he broke through Hongyi's firewall, invaded his computer and gained control. .
Hong Yi stopped moving, her fingers trembling slightly, how is that possible! How could she be so fast! All defenses seemed to be vulnerable in front of her. Who is she?
It was clear who won and who lost, and the whole audience was shocked!
“How is it possible? Hong Yi lost!”
“Who is Su, and where did he come from?”
“It’s so perverted!”
Bai Ye was so excited that she danced, "Fuck, it's awesome, Master, it's awesome!"
Lan's pupils tightened. The master Bai Ye recognized was so powerful!
The people in YN looked livid, and no one expected that Hongyi would lose to an unknown young man!
The face of Liehuo is almost ferocious, and their red clothes have actually been used as wedding clothes for others!
After today, there will be another legend in the Chinese hacker community! A legend who broke through the red coat in ten minutes! The legend of a young top master!
