[Hidden Masters EP.3 Winner of World Hacking Contest /
Today's master / A high school student who won the World Hacking Contest] In the past there was a very popular meme The billboard of The Chosun Ilbo was hacked by a middle school student! How do people do that? That is called hacking... By the looks, it's funny It's funny When we look at hackers in movies... The world is crazy The highest price that was offered to me was xxx dollars a month You don't sign a contract Your life can be ruined [Hidden Masters] [Real geniuses who are hiding their powers] How much do you think you know about hacking? In movies and dramas, hackers always appear like a cheat key How realistically were they expressed? It's not completely opposite of the reality but I don't think it's that close Here there is the top 1 of world hacking contest someone who hacks the best in the world a high school student We will listen to what kind of fields are in hacking and what process hacking has and troubles that give you headaches when you live as a hacker And with a prize of 1,000,000 won, we will do a high-class battle that suits today's world-class guest [What kind of battle is he fighting...?] I think there is a fan sign meeting [A street fan meeting in front of a school on their way to work]
There is a fan sign meeting [Today's school / Arrived at Sunrin Internet High School!] We are going to many places I think there will be many great people [Hidden Masters]
Real geniuses who are hiding their powers There are many experts in this world And today Please tell us who it is It's a field relevant to computers In that field, he won the top 1 place in a world contest A world contest? Right now, he is wearing a unique costume and working diligently for the safety and security of the school Today, you have to find that guest This is Sunrin Internet High School It's the first modern vocational school and firstly, the school is about 120 years old 120 years? If it is 120 years, we used internet when emperor Gojong was in power? Oh, I'm sorry but I think this is an important call and can I get it? Yes Oh, hello What is that person doing during shooting? Should I teach him a lesson? [Entered the school to find today's guest!] Wow, what is this? Oh, statue of Sopa Bang Jung-hwan [School of Bang Jung-hwan who made Children's day!]
Colleague Bang Jung-hwan, he is the 8th graduate of the school Oh He must have liked sofas Oh, please don't do that You would be scolded... Huh? [A student who is on patrol wearing a fluorescent jacket in the middle of the day?] Oh, hello Yes, bye... You must be today's guest! This person won the top 1 of a world contest... Hello, nice to meet you You were forced to wear this and you were forced to old this and to the PDs who made you... [(Reality hit 100%)] You didn't need to do this... Please introduce yourself I'm Lee Seojoon I'm studying hacking in Information Protection Department of Sunrin Internet High School [Lee Seojoon (Today's real genius)] [3rd grade of Sunrin Internet High School] [Winner of world hacking contest, school sheriff] Oh, do you study hacking? Are you top 1 of a hacking contest? Yes Top 1 of world hacking contest? Yes Then after appearing on this video, will you get caught right away? Oh, no It's a mock hacking it's a mock hacking but you can use the skills in reality Of course You do it to use it in reality You use it in reality For good purpose Oh, for good purpose Well, everyone says so Firstly, before hearing your story, can you give us a tour of the school? [Let's look around the school / that made the winner of a world hacking contest!]
I think we should take a look at that No.1 building Firstly It's an internet high school How many computers are there? I think there are over 300 Is the internet speed fast? Oh... It's quite fast [Unique name, what is Sunrin Internet High School?] Our Information Protection Department There is 1st grade classroom This is Software Department What is the difference between Information Protection Department and Software Department? Information Protection Department deals with security and Software Department deals with development [We heard that this school has active club activities!]
Are there clubs in this school? Seojoon, what is your club? Hacking club With 20 years of tradition! Then what do you do in a hacking club? Do you have battles too? Yes, right There is a competition and we have such activities Oh, what is this? [Many award history of hacking club]
They are certificates that we received from hacking contests Seojoon's club is famous for hacking nationally It is called Layer Seven [When entering a contest]
and when you enter a contest and say Layer Seven, most people know about it Oh, really? What is this? Discharged girl's high school growth team It's a cyber operation contest Great You do things relevant to security There are contests held by Ministry of National Defense If you win, do you receive offers from the Ministry of National Defense? I have never received an offer but a person from the Ministry of National Defense said 'Come to the military' 'We will treat you well...' Perhaps They can treat me well so I keep that in mind Why are the team names so unique? The team name here is 'the action of a puppy whose owner had taken its bed' Is that the team name? The name of a senior that I know 'Seeking for Kim Jong-min's Christmas date duo' But it's the grand prize I wish Jong-min would go on a date... Among your teams, which team name is the most memorable? I remember winning 2nd place and when they called out the team name, 'Lee Seojoon looking for a girlfriend...' LOL So did you make a girlfriend? I didn't Oh, what a shame Do you have a girlfriend now? I don't I see... [1. Simple hacking demonstration / How do you hack?] It is used as a practice room and it's a place where we receive lessons in our club I will turn on any computer and show you hacking When did you gain interest in computers? When I was in 3rd grade of elementary school, I played Minecraft [MOD(game term) / A version where they added a new function by changing elements of the original game]
There is something called MOD and I wanted to develop it so I learned programming and as I studied, I gained interest in hacking Many people started with Minecraft Really? Hacking, let's assume that we are hacking the internet What do you need to know in order to hack? You need to know how a server is run in order to find its weakness and hack You need minimum amount of information For example, there is our homepage There is a site called Geekble shop Let's say that I want to control Geekble shop Then what should I do? If you look here, there is developer tool and there is a lot of information that you can obtain from here You can see which server it is using It says engine X [Hidden Masters / How does hacking work?]
It's server software It's server software From time to time They're going to show you, the version of this software It's a well-known software in this case, If a vulnerability is found, [Standard code created by experts to share and work together to solve vulnerabilities]
It's called "CVE" and vulnerabilities are registered If you find out the version, you can find it there I'll use that We can take control of this server Once upon a time, There's a really popular meme "The Chosun Ilbo's billboard got hacked," right? How do you do that? That's, It's hard to say it's a hack It's funny That's funny? On the billboard, There's a remote control program called Teamviewer There's an ID and password It was exposed on the billboard So the person logged into the program with it like he or she hacked it - Their ID and password were revealed then?
- Yes It's not a hack The person caught their carelessness, He or she just went in [Taking out information physically through visual and other means]
- It's actually a physical hack
- That's right x2 Can you hack it if you make up your mind? I don't have a lot of information Geekble shop hacking is kind of hard? But you're the winner of the world hacking competition Can you get into the system it if you have time? There's no time limit If the time is infinite, it can't be invincible It's supposed to show that there's a vulnerable spot - I've got this question a lot
- Yes Please tell me that you can get into the system That's how it ends Can you get into it? I can - If time is infinite
- I knew it Wouldn't any shield be broke at least once? It can be broke through Then I'll [Simple game / A very simple demonstration of the hacking process!]
I'll show you how to hack into a game called "Pikachu Volleyball" - Does it work in real time?
- Of course What is this program? This is called a cheat engine I use it a lot when I hack into games Do you think about hacking while playing games? Sure, let's do it Have you ever done it? I've tried it I haven't dug deep into it yet You can't do it Right, it's illegal Pikachu Volleyball hacking is okay, right? There are no victims I need to get some information There's a score. It's 1, right? Then search for 1 If it's 2, search for the value that changed to 2 You need to know where it changes If you look for it, it comes up like this, at each address what kind of information it contains - Are you recording it?
- That's right Over there If you put something else in - Does he get confused?
- That's right Looking at it like this I get it? I should try the cheat engine, too? Is it a paid program? Cheat engines are, free Thank you [(Computer) / (Seojun)]
Like this, I lost and my score went up... [(Seojun)]
My score went up... Even if I win or lose I always get higher scores That's right Even though I just won, I went up here Even if I die, it goes up Right, our side goes up On the contrary, You can cut the other team's score After changing it like this The command you just changed, - Did you change from increasing to decreasing?
- Yes If you change it, your opponent's score will go down Pity I hacked it like this The software didn't mean it I can change it however I want What happens if it's -1? If it's -1, the game will turn off It's pretty simple, right? Did you have fun? I had a lot of fun I don't think you can't hack games these days Can you hack LOL? As for online games Changing the score The server takes care of it Unless you're hacking into the server To completely change the price is hard For example, if you play Battlegrounds, Something like Aim with information from the information I can make you help If I killed them all This is not easy, right? That's why Battleground has the Aim Hack It's an online game If you don't take care of it properly Client Do you know if I say that? [(He was provoked)]
I know clients! Why don't you know the client If you tamper with the side installed on your computer It's not supposed to change on the server In the past, on Battlegrounds The coordinates of the opponent's character Change it to the front of me Even if I shoot him There was something that was recognized by the server [It was very simple, but the explanation makes sense]
It's blocked now [What happens when you know how to hack /
The worries of the winner of the world hacking competition] [To live as a hacker]
Hacking is actually, It's the first time I've seen it We saw the process roughly In a way that's easy for us to understand You showed it to us If I really want to hack it I was so curious about what I needed first Go to the website and Press F12, look at the information I'm looking for vulnerabilities It was so fascinating. So, we're going to have an interview After it's over We have a battle ready You don't know yet Let's play a game that's advantageous to the main character We're going to prepare it If you win that battle? [1 million won in cash] [(First time hearing it)]
You will take 1 million won in cash right away You didn't know this? I only knew that there was a competition I just saw Seojun I saw his lips shaking I'm already excited You're excited? How much did you win in the world hacking competition? [20 million won] We're only 1/20 of that I'll give you a chance I want to hear from Seojun [What do you do at the hacking competition?] At the hacking competition, It's called "CTF" It's called Capture The Flag If you analyze the software there are succeed in a challenge I'll say there's a box in the house There's a vulnerability in the door The door opens when you put the needle in. You went in there and brought the box If you check the contents of the box You can think of it as a flag If you submit that flag They'll give you points Anyway, Most of hacking competitions are, Capture The Flag CTF It will be in CTF format Then the winner The World Hacking Competition It's the World Defense Hacking Contest, right? Hacking defense This is KO-WORLD Hacking Defense Contest From high school students all over the world It was a competition where even college students could participate The seniors who came from my school and I participated in the finals together Luckily, I won the first place What was your assignment back then? It was done in CTF format To be more specific Will we be able to understand? The event, It's called "Pwnable". It was almost Pwnable there I'm going to analyze the software on the attack site Once I have administrator privileges I'll be able to do some activities in the server There's a flag file in the server If I read it, they give a flag For Pwnable It's called system hacking By exploiting the server's If you have administration authority [Hidden Masters / 2. Living as a hacker] If you get admin authority, you can access the server for info like user id
or birthdates, all of this can be stolen Sensitive info is also vulnerable [2. Web Hacking] There's the web field Web hacking can be easy in a way but also not so much There's this brute force attack Also known as forceful entry On a website if you get the password wrong
too many times, you can get locked out if this safeguard is not set up this website can be hacked as long as you have a working user ID You can get the password in this
scenario by using brute force attack in the worst case [3. Reversing (Speaker's
specialty)] Another area is reversing That's my field You've heard of cracked versions of
windows? No need for activation... That's a form of reversing Inside windows, the work process is analyzed to make it look like an authorized
version The part that shows if the s/w has been activated is what I get rid of It's hard to explain You can compare it to solving an equation You get the software and input a string You alter that string and compare it with what's saved in the software if the value is correct, a flag comes out The altering process is analyzed Then you reverse calculate the saved value and change it Now you know what to input That value becomes a flag most of the time I didn't realize hacking has so many areas Depending on the area the work that hackers do changes? That's right For reversing, a lot of it is dark It's all around us, like game hacks are examples of reversing For Pwnable, you can be a vulnerability researcher in most cases If a company develops software, they hire a subcontractor for
vulnerability analysis work So the people in the Pwnable field
does this What we usually think of as the white hacker image, that's normally it? Yes When is reversing used on the white side, can you tell us? The border between pwnable and reversing can get blurry Because Security companies do some pwnable analysis is how people in this field become
researchers Reversing also does a lot of analysis So Seojun what kind of work would you like to do? Have you heard of EN Key? TOUCH EN Key? Yes It's that the virtual touchpad company? Is that from there? I get confused I'd like to work for some company like that to do vulnerability analysis So what about hackers in the movies? You know... [Black hackers featured in movies
involved in crime...] When they do it,
it's as simple as hitting the enter key. In the movies, the hacker always says the player enters Have you done that? No How do you feel when you see that? [A black hat criminal hacker hacking
security systems in real time...] That would only happen really when companies don't care about servers and have old software running, That's the only case In the movies you see attacks happening in real time That is possible but that's more cyber attack than hacking It's not completely different from reality but also not close either... What normal people consider hacking is mostly black hat hacking so this misconception can't be helped I wish the white hat stuff would get more media attention but the field is very narrow right now I wish it would grow more. If you become a black hat hacker you cause damage to companies and unspecified amount of people as well Ethically speaking, I don't think that's good If you enter competitions, the prize is very hefty Instead of getting into crime by becoming a black hat, I feel that getting fame and prize money is a better choice [Q. Why did you start hacking?]
I wonder what got you into this field. I started off with coding Then learned how vulnerabilities are
made possible As I learned more and more, I really got into it There are many different forms of
vulnerabilities As you get deeper you find more vulnerabilities which I found attractive You said you started with Minecraft? I'm not sure if this is still around, [Redstone(Minecraft)/Similar to
programming logic, it's a tool to
make circuits.] there's Redstone. You can
mess with circuits but there's limits I wanted to build a module That's how I started (programming) (Through hacking) I wanted to exploit the vulnerability in this game So you wanted to add a function that
did not exist into the game forcefully? There's guides out there for game hacking Also, there are open source games, I used that to start studying When you get into it with real passion, you find everything from search engines What I really learned was how to search to find this type of information You started with coding To insert functions the game didn't allow you hacked it to insert these functions. So naturally you started on the path to hacking Yes Wow, this kind of tech is possible? [Q. During your studies/were there any
reference sites?] During your self
studies, did you join any hacking
communities? This is a dark site called Unknown Cheat There's a game hacking forum They have a lot of information on
windows as well as other games There the people on the forums show of their creation It's called a showcase You make a video showing what function you made possible, then the comments comes up It's cool, share with me, there's something akin to the like button If you get a lot of likes there you get a private message from the dark side That's more common than people think I've received offers as much as $4000 a month However, those cannot be trusted It's not like people on the dark web provide contracts or anything so I don't really want to get into something bothersome That can ruin your life Things like Hacking competitions, Korean contestants are getting prizes pretty often But the security there is very tough, that's what I heard I hear that it's hard [Why are there so many voices of concern in the security industry?]?]
There are so many talented people, Why are there so many people saying it's hard? First, in the job market, up until now There are a lot of places where they look at my academic background Even if you study hard (hacking), If I don't study general subjects, I can't go to school So the difficulty is That's what I'm thinking Then, Seojun, on a general subject You've been stressed out? From the 24th grade, Like self-introduction letters, It shrinks I'll take care of my school records first, I'll go to school If it doesn't work, [He might retake the college entrance exam] If you don't mind, What's your current GPA? I'll get grades 6-7 Hey, you too? Hey, me too! When I was in the competition, I'll be absent if I go out on a competition I can't take classes, I didn't know anything Especially math, If I don't know the concept, I can't solve it I picked the answer in one line and slept Even if your grades are 6-7, your hacking skills - It's good enough to win first place in a competition
- That's right Is there no such thing as that? There's a selection of specialists Everything gets smaller, accepting my award, there aren't that many options Even if he's as active as Seojun If you're going to college or something like that, If there's a stumbling block, - I don't think there will be more people hacking?
- That's right In the end, who learned how to hack about the people who do, there needs to be something to help. It's not easy So, I always, We have a new student in our club To study hard for your school grades, I'm telling him not to miss it But if that happens, He can't study hacking a lot - He can't participate in many competitions
- That's right It's not that you don't care about entrance exams, you really want to study and met people who are good, while listening to the background, There are things that I want to change. I hope it goes well Now, the rest of the segment is [Last person / A grand competition that costs 1 million won] an interesting contest Please show us Today, What will Seojun compete against Don't you have a good idea of hacking. Whenever you hack, don't you play a lot of keyboards I guess so? Something that comes to mind intuitively Something you can only do well I'm so embarrassed because I think I know what it is What do you think? - Typing?
- Right [Match / Typing competition with the winner who have first prize at hacking contest] We invite the winner of the World Hacking Contest, Is that typing practice? Yes, it's a typing competition If you're the winner of the world hacking competition, you have to type well It's incredibly advantageous What's your average score? I do it quickly I think you're confident? By all means Are you nervous or Do you have time? I'm a little nervous I think I'm more relaxed now... We have to do the same mission, right? - At Hancom Typing Practice
- Right Are you confident, S.Dragon? I'm not a fast typewriter Then I'll do it No, I don't like that Hold on. Please level the playing ground Let me do it with the code I wrote During Hancom typing practice you can put the script in That's kind of cool [It might be advantageous for the main character / Who will be the winner?] [A competition for 1 million won / The speed of the winner of the world hacking competition] Guys The typing contest is, 2 wins out of 3 And the first topic of Test, [The first topic / (National rule) Night of counting stars] At the end of the first page, It's automatic I'll rank it at that rate [Prevention of cheating / Fail if there's a typo] [(Burdened 100%)]
Here we go. Are you ready? I'll give you a sign Ready, go [As expected, the typing speed is consistent!] [On the other hand, S.Dragon was not confident]
Let's go [(Entering the 3rd row)] [(S.Dragon is speeding up?)] [(In a hurry)] [(But the main character too!)] [(Another mistake at the last minute!)] [Both passed / Round 1 is over!] [Seojun's record: 29 seconds, 523] And S.Dragon, [38 seconds] [S.Dragon record: 38 seconds, 409] [The score is out of the league] No, I said I would do it if you were going to do this [Round 1 / Seojun wins!] [(Already thinking about where to spend 1 million won)] Give me an advantage The second round is, S.Dragon, [The loser chooses the theme!] The code I wrote! There's a code I wrote Let's bring that up as a topic Are you okay? - Me?
- Yes. If it's not okay, Do we just do it? If it's not okay, We can talk about it together [Thinking about using the code / that he wrote]
How can I do this Why can't you do this Seojun, are you okay? But this The coding code is, There's going to be some typos [Never seen typing practice in his life] I think it's good What do you think - I think it's worth trying.
- Is it worth trying? S.Dragon, this code is, you've seen each other for years You have nothing to say Okay, then right now They'll try these five lines If Seojun wins this time, 1 million won is Seojun's Are you ready? [How will S.Dragon / ingenious strategy work?] Ready, go There should be no typos It's neck and neck? [First of all, similar progress?] This round is so much fun? S.Dragon, fighting [(But it's already the last line)]
English is really fast [There was a typo?] [(Disappointed)] [On the other hand, S.Dragon calmly finishes] I can't do this anymore I can't do this Wait a minute Well... My hand slipped... At the end, there's "Pin_R_Text 8." It became "Pin_R_Text 9." You must have typed 'Text' a lot Your hand moved that way automatically You're sweating right now? Although S.Dragon finished late Because there's no typo, [S.Dragon won dramatically in Round 2!] I survived [(A close call)] [Survived luckily] Let's go with English typing Seojun has a chance to choose the topic Do we have a chance to change players? No there's nothing like that [Being legit after losing once] His hand is sweating now [Being legit after losing once] Let's go on with Rapunzel in English typing [Last topic] (English typing) Rapunzel It's the last round You're out if you miss typed something although you're fast S.Dragon you can take off your apple watch Ready, start! Oh they're concentrating [Extremely fast typing English] [Strategy not to make a miss] They should concentrate typing Being fast isn't that important Seojun is concentrating now Oh he's over Make it completed x2 We don't know the result actually yet -We don't know it yet
-We don't know it yet What don't you know yet So for the 3rd round, [Seojun won the 3rd round with no accident] Seojun won the game! Congratulations! Seojun's record : 41 sec 415 speed. S.Dragon's record : 72sec 235 speed Seojun dominated the game What will you do with 1,000,000 won? I'll buy my camera lens You're using it in a good way Congratulations with your 1,000,000 won!

Was it fun? Oh I actually enjoyed it It was really an honor to meet you We also enjoyed a lot Hacking is actually a curious part, so I wished to see it for a long time, and I finally saw it in real for the first time Do you have words to say it for the last time? I hope everyone who enjoys their majors cheer up and study hard on basic studies too He's actually suffering that Fighting Seojun from now on! Got it One, two, three! Geek-Bye! [S.Dragon training to be a programing expert?] Have you enjoyed the hacking episode? I've started to study codes newly after filming the video We've got a program which is really good related on coding 36 weeks course of Devel rocket It's a bootcamp or block-chain creator You can learn about block chain, which is for protecting various areas using credits You don't need to pay for it, cause it's 100% supported from the nation Plus, there are chances provided to get on a project with several IT companies!
