Unexpected qualifying for the ninth quarter

On October 12, 2006, the much-anticipated World Hacker Conference officially began. Pen, fun, and www.biquge.info

Because of the fact that the real top hackers, especially those who have black records in the archives of various countries, do not like to reveal their identities, this hacker conference did not take the form of a physical gathering in the past, but took the form of an online gathering.

From a certain point of view, the previous hacker conference was more like a friendship dinner, but this hacker conference is like a real hacker conference.

You can't see anything but everything on your computer screen, except for a myriad of codes made up of 01s. You don't know what the look of the person fighting you on the other side is, you don't know his expression, you don't know anything, you just know that he is your opponent, he wants to break you, and you have to fight him.

It was as if everyone was fighting against the night, and he himself was a part of it.

As the team leader, Duan Tianwolf logged in to the host of the hacker conference with the code of the invitation letter given to him by Jin Yue, and the examiner manually verified his invitation from the remote one. They are then assigned a 16-digit entry code.

In the past ten days, Duan Tianluo has done this matter I don't know how many times, so he can't be more proficient.

After getting the entry code, Duan Tianwolf took out a period of time, the interface he and Sun Yunmeng made together was very simple, the entire file was less than a trillion, but the core was extremely strong, and it was almost impossible to be hacked by hackers, and the communication software was transmitted to Ling Xue and Duan Di Tapir.

"From now on, all our communication will be through this messaging app. This messaging app is completely closed, and it is impossible for anyone but us to enter our conversations. ”

Before hacking others, you must first prevent yourself from being hacked by others, which is common sense for hackers. Especially now when there are top hackers everywhere, so Duan Di Tapir and Ling Xue didn't say anything, and immediately downloaded Duan Tianwolf's communication software and installed it.

Then, they began to communicate personally in this communication software named "Security Company" by Sun Yunmeng.

The first to speak, naturally, was the team leader Duan Tianlu, "This is the entry code distributed to us by the hacker conference-2309588¥%#der. Log in to the hacker host, enter this code, and we will be personally grouped into the same group. After that, we started with the host and connected to server number seven, where we tested it, and our group's code was number 188. ”

"One hundred and eighty-eight? Yes, a very auspicious number. Sun Yunmeng smiled in front of the computer screen and said.

"It's a pity, the prize of the competition is not a bonus, otherwise, just from the group number, we should also win the championship." Ling Xuesheng also continued.

Sun Yunmeng was very relaxed, and the others were just as relaxed as Sun Yunmeng, even Duan Tianluo didn't care too much.

Today's tournament is just a qualifier, and it's just a match against a server that's already set. The Utopians all thought in their hearts that there was really nothing difficult about this level of testing.

The really hard battle starts with the P match.

"Okay, it's only a qualifier, but you have to cheer up, if you accidentally get wiped out in the qualifier, it will be good. Also, the entry code is case-sensitive, so don't make a mistake. If you make more than three mistakes, you will be disqualified. Although he was not very nervous about the qualifying tournament in his heart, as the leader of the group, Duan Tianwolf still had to spur on.

"Got it, leader."

"No problem."

"Okay."

After the three of them answered, the individuals logged in to the main server of the hacker conference one after another.

"Once the identity of the group has been confirmed, please click the link below to enter the test server."

Below this sentence is an internal link that the Utopians all clicked on.

Soon, they were personally on the same page.

"Holy, isn't it? Did you click on the wrong link? As soon as he entered, Sun Yunmeng shouted in the "security company".

Not only him, but the other three couldn't help but shout in front of the computer: "Is there a mistake? ”

It turned out that when they entered this page, instead of seeing the server's test introduction, a huge window popped up, which took up almost the entire page, and could not be closed.

In this window, first a lady with at least three catties of powder on her face rushed out, her body was in an S shape like Sister Furong, holding her face with both hands, facing a box of yellow and shiny pills, and shouted in a disgusting voice: "Donkey Er Kidney Bao, he is good, I-am also-good." ”

After reading the lines, the eldest lady shy hid her face and retreated.

Immediately afterwards, a middle-aged uncle came out, with a sad face, and at first glance, the surname life was extremely incongruous, but he made a well-informed and high-spirited look, "Like us programmers, who doesn't have hemorrhoids every day?" There used to be a few days a month when I felt pain when I put it on a stool. Since having Shutai, everything has been fine, and with Shutai, you can sit for as long as you want. To treat moles, use Shutai. Shutai, I said it was good to use it. ”

Then, a mentally handicapped man with glasses half an inch thick appeared, holding a blowing doll in his left hand, putting his right hand to his mouth to make a whisper, and reading with a lewd expression on his face: "Sex brand sex doll, who uses it knows." ”

After saying that, he threw a wink at the screen.

Advertisements like this, over and over again, over and over again, endlessly, make the utopians have the urge to kill the hacker conference.

When the famous blockbuster "Transformers" produced by the famous American director Spielberg was screened the following year, many viewers below had opinions and shouted that there were too many advertisements. And those hackers who have participated in the hacker conference, after seeing this situation, their reaction is almost exactly the same - shaking their heads, sighing, and then silently saying in their hearts with disdain: "I have never seen the world, I think we ...... when we participated in the hacker conference."

, no more gossip, let's get back to the point.

I don't know how long I waited, but in short, when the Utopian group was about to fall asleep, the advertisement finally ended, and the window automatically shrank back, and then I saw a few lines written on the page, "Because this conference is too expensive, the organizers have to carry out a low degree of commercial operation of this hacker conference, which causes inconvenience to everyone, please forgive me." ”

"Damn, this is also called a low degree of commercial operation? So what is a high degree of commercialization? Is it necessary to sell all of our participants in order to be considered a high degree of commercial operation? ”

Like many hackers who participated, Sun Yunmeng scolded in front of the computer, and then saw that this subface automatically disappeared and a page popped up again - "According to the original schedule of the hacker conference, the qualifying tournament is based on a point system, and the top 36 teams can advance to the qualifying round." However, because the points system has too strong human factors, in order to avoid controversy. Under the guidance of Hongjun, the top instructor of this conference, the qualifying competition was changed from a point system to a three-level elimination system. According to the rules of the three-level elimination system, the qualifying round is divided into three parts: password cracking, vulnerability finding, and hardware firewall attack. Only those who pass all three levels will have a chance to advance, and the team that fails in any of them will be eliminated. ”

This page appeared for three minutes, and after almost everyone had finished reading it, they went to a page again.

The first level, password cracking.

Content: The test server will provide you with a 512-digit password, which is the latest encryption algorithm written by Hongjun himself. If the world's most advanced supercomputer were used to brute-force the crack, it would take about 132 years.

The duration of the competition is limited to 100 minutes. During this time, the password will be automatically changed every 20 minutes.

Teams have a time limit to predict what their next password will be.

If the team's predicted password matches the automatically changed password, it will be deemed to pass, and if it does not match, it will be regarded as a failure.

The teams that pass will be automatically transferred to the next level, and the teams that fail will be kicked out of the test server.

Keyword hints: fast Fourier transform algorithm; Computer Fundamentals.

If you're ready, click Yes, if you don't click Yes within 10 minutes, the system will rule that you are abstaining.

The Utopian group, who originally felt a little relaxed, all took a breath of cool air after reading this paragraph, it seems that this qualifying tournament is not so simple.

"That old guy in the legend isn't playing tricks on us, is he?" Before clicking to enter the test, Sun Yunmeng said in "Security Company".

Ling Xue continued to say: "I also think that the qualifying tournament is so perverted, if the qualifying tournament will wipe out all the contestants, it will be interesting." ”

"As long as there is one team that makes it to qualify, that team has to be us. Without further ado, are you ready to achieve what I want everyone to do? ”

"No problem." All three replied at the same time.

"Let's get started!"

Duan Tianwolf said, using the pen on the PD screen to click the word "yes" lightly.
