Room for Anne Batch and MechMK1

10:53 AM

@AnneBatch I'm so sorry to hear that. I can imagine how awful you must feel now. But if you really want to go, you can try finding work in software engineering now and apply for university again in a year. I believe in you!!

Anne Batch

3:42 PM

@MechMK1 Thanks, you're the best.

How are you friend?

MechMK1

@AnneBatch Doing okay, still stuck at work

Anne Batch

Are you working now?

MechMK1

The weather has been awful for days now. It keeps hailing and snowing

Yeah, but it's fine

Anne Batch

@MechMK1 Wow, snowing is nice!

@MechMK1 You had a vacation for a few days

MechMK1

It is, except when you have to go 30 minutes to the grocery store and a hailstorm breaks out

Yes, monday was a free day

Anne Batch

3:44 PM

@MechMK1 Lol. I agree

Your company is lucky to have you

MechMK1

Awww, thank you

How have you been the past days

Anne Batch

I believe that as far as possible. And you?

My english is bad

MechMK1

No, your english is fine

You're doing incredibly well

Anne Batch

Haha, thanks

Btw, why do you speak English? Is it the mother language from your country?

MechMK1

No, my native language is German. I just learned english in school and practiced it for many years.

Anne Batch

3:48 PM

Ohh

You're smart

Wie geht es dir?

Haha

MechMK1

Very good!

And it's really just practice. If you practiced german for 16 years you'd be pretty good at it too

Anne Batch

That's true

Look

Can I ask a question?

MechMK1

Of course!

Anne Batch

I would like to know what is the best language to learn to create scripts to hack? I like this concept, when I saw that you created a script that showed the time on your keyboard, I felt "woow", so I would like to be able to create things like that

MechMK1

For hacking, you can use any language to feel comfortable with

Ruby has the advantage that you can use it to write Metasploit modules with it

Python is very common too

I've written a nice exploit in Java a year ago

So you can really use whatever you want

Anne Batch

4:04 PM

Hmmm

I would like to learn Java because of the syntax

Let's say I want to create an keylogger, how many lines of code do you think it would be possible to create?

MechMK1

Keyloggers are really not that difficult

And I would recommend C# instead of Java

Because Java is a pain in the ass

Anne Batch

@MechMK1 Haha, why

MechMK1

Java's stream API is horribly designed

In C#, you have really nice easy functions, like File.ReadAllBytes()

In Java...ugh, so much code

Anne Batch

It sounds good

MechMK1

In C#, you say `Console.ReadLine()`

In Java you need 10 lines for it

Anne Batch

4:09 PM

Pretty much code in Java

MechMK1

Trust me, C# is what Java dreams of being

Anne Batch

I hear you, but... What do I need to start with C#

MechMK1

You can download Visual Studio Community edition

visualstudio.microsoft.com/vs/community

Anne Batch

Great! I have it

MechMK1

Nice

Then you can start with simple console programs

Anne Batch

4:11 PM

Do we need any compiler?

MechMK1

That's all built-in

Anne Batch

Ohh

MechMK1

You can just click "Run" and it will run

C# Tutorial - Full Course for Beginners

►

This could be a good thing to start

Anne Batch

Perfect

I'll watch this entire video today

Starting now!

MechMK1

Nice, I hope you enjoy it

If you have any questions, feel free to ask

By the way, do you use Steam?

Anne Batch

4:16 PM

@MechMK1 Thanks

@MechMK1 Actually not. Is it for gamers? Explain

MechMK1

@AnneBatch Yeah, it's a platform for videogames. If you don't use it that's fine

Anne Batch

Do you want me to play games with you?

MechMK1

@AnneBatch I thought you could add me on Steam so you can send me a message there. I'm generally more easily reachable there than here on Stack Exchange

But if you don't use it, then you don't need to make an account

We can just talk here

Anne Batch

Sure. I'll create an account

MechMK1

If you want

Anne Batch

4:24 PM

What's your nickname there?

Is there any difference on VSCode?

Visual Studio community is different from the one I have?

MechMK1

steamcommunity.com/id/mechmk1

VSCode is much smaller and has far fewer tools

So think of Visual Studio Community Edition as the "standard" version

VSCode is the "Lite" version

And Visual Studio Enterprise is the "full" version

Anne Batch

Ohh

MechMK1

For example, one amazing feature is the debugger

It allows you to see and modify everything

While you run the program

It's really helpful to see the state of each variable at any time

Anne Batch

In real time?

MechMK1

Yes

Anne Batch

4:28 PM

It sounds good

MechMK1

You can set a breakpoint, step through every line

You can even modify the code while you run it

It's incredibly powerful

Anne Batch

Indeed, an amazing IDE

Should I uninstall my Lite version and install the Community Edition?

MechMK1

Oh, you have VScode installed?

Yes, I would recommend switching to the community edition

It's a big download, but it's worth it

People like VScode because it's tiny

Anne Batch

Your account does not meet the requirements to use this feature. Visit Steam Support for more information.

Steam

MechMK1

You can't add me?

Anne Batch

4:31 PM

@MechMK1 Ok I'll do it

MechMK1

Weird

Anne Batch

@MechMK1 W8

steamcommunity.com/id/AnneBatch

MechMK1

s.team/p/gvk-kwpw/MVGPMGWM

Does this work?

Anne Batch

Yes

MechMK1

Nice

Nice, there you are

Anne Batch

4:35 PM

Yeah haha

You're really a big gamer

MechMK1

Maybe

Anne Batch

Do you hack steam games? Haha

MechMK1

Sometimes, yes

But only singleplayer games

I don't cheat in multiplayer games

Anne Batch

@MechMK1 Lmao

MechMK1

It's fun to hack games

Anne Batch

4:36 PM

I think so

You're a professional

MechMK1

I am, yeah :D

But I still have so much to learn

Anne Batch

@MechMK1 That's easy for you

Is your mom or father a technology lover?

MechMK1

Not really

I had to learn it all on my own

I was really envious when all my friends had fathers who were really into computers and knew a lot

And mine was always yelling at me when I am in front of my computer

Anne Batch

@MechMK1 :/

Now he's probably proud of you

MechMK1

No, he still thinks I'm a loser

Anne Batch

4:39 PM

@MechMK1 Give me tips?

MechMK1

Sure, I'd love to help you learn with anything you're interested in

Anne Batch

@MechMK1 Wow, that's sad... You're not a loser, you're a winner, a hero.

@MechMK1 Maybe I can pay you to teach me

MechMK1

I wouldn't go as far as calling me that, but I'm glad you don't see me as a loser

And no, I wouldn't want to accept payment

I'll help you just like that

Anne Batch

Thank you so much

Sometimes I want to be a hero hahah

I want to break systems

MechMK1

I'm sure you can learn how to do it

Anne Batch

4:41 PM

But I don't even know so much about programming

MechMK1

Hacking isn't all about programming

It's about understanding how things work

Anne Batch

You're right

Tell me

What do you think about deep web? Is there really expert hackers?

MechMK1

No, that's all BS

The "deep web" is not nearly as interesting as people make it out to be

Mostly just people buying and selling drugs

Anne Batch

@MechMK1 I agree!

@MechMK1 And also child pornography

MechMK1

Unfortunately, yes

But luckily law enforcement is arresting those people

Anne Batch

4:44 PM

Good to hear that

Crazy people

MechMK1

Yeah, they're sick

Anne Batch

And what do you think about hacker groups, is there really something like anonymous?

@MechMK1 haha

MechMK1

Yeah, of course

Just people who have hacking skills and usually some political cause

Anne Batch

What do you mean by political cause?

MechMK1

Well, usually hacker groups want something

If they just want money, we just call them regular criminals

But anonymous has a political agenda

Or it used to. I don't think they are active anymore

Other hacker groups just do it for fun

Anne Batch

4:48 PM

@MechMK1 Why do you think they're not active?

MechMK1

For the same reason a lot of groups disband: Members started to get inactive or just started doing other things

Anne Batch

That makes sense

Did you see about the leak of data in Brazil?

MechMK1

No, what happened?

Anne Batch

Really?

Data from more than 200 million people were leaked

MechMK1

Oh wow!!

Anne Batch

4:53 PM

I thought you knew

MechMK1

No, first time I heard of it

Anne Batch

I see

We need you to protect our data :d

MechMK1

Yeah, a lot of breaches happened because of the recent Outlook vulnerability

Anne Batch

Outlook vulnerability?

I didn't know about it

MechMK1

2021 Microsoft Exchange Server data breach

A global wave of cyberattacks and data breaches began in January 2021 after four zero-day exploits were discovered in on-premises Microsoft Exchange Servers, giving attackers full access to user emails and passwords on affected servers, administrator privileges on the server, and access to connected devices on the same network. Attackers typically install a backdoor that allows the attacker full access to impacted servers even if the server is later updated to no longer be vulnerable to the original exploits. As of 9 March 2021, it was estimated that 250,000 servers fell victim to the attacks,...

Anne Batch

5:03 PM

Wow, that's awesome

10 groups of hackers?

MechMK1

A lot, yeah

Everyone was on it

It was basically free money for criminals

Anne Batch

@MechMK1 They asked for Btc in exchange for the encrypted files, right?

MechMK1

Some did, yes

Some also used the internal information to send phishing emails

I've got to go, but I'll be back in an hour or two

Anne Batch

Ok

See you, thanks

Take care of yourself

Anne Batch

7:12 PM

@MechMK1 Watching the C# tutorial right now :D

MechMK1

@AnneBatch Nice!

If you have any questions, feel free to ask

OK. Thanks

You're welcome

I have a question

Sure

7:13 PM

static void main()

Every function needs to start with static void ?

MechMK1

Yes, what about it?

No no

Anne Batch

Isn't public function?

Oh

A little bit different

MechMK1

the full line is

public static void Main()

the main function needs to belong to some class, usually something like Program or Application

public means the function can be called by things outside the class. In case of Main(), the OS is calling the function when running the program

Anne Batch

@MechMK1 Just these two classes?

@MechMK1 That's weird, because there's no public in my code

MechMK1

@AnneBatch Well, Main() is a "special" name for a function, since it's the first function that gets called when your program starts

It's the entry point

Anne Batch

7:16 PM

Main() is the constructor?

MechMK1

@AnneBatch I think it's possible to skip the public for Main()

@AnneBatch No, a constructor is something else. Main() is the "entry point"

Basically where your program starts

Anne Batch

@MechMK1 Good to know

MechMK1

In script languages, the script starts "at the top", in C# the program starts in Main()

Anne Batch

Ohh

Firstly the program will execute the Main() function?

MechMK1

Exactly

Your program needs a Main(), or it will not run

Anne Batch

7:19 PM

Very good

@MechMK1 If my program needs a Main(), then I need to create another methods inside _Main()?

MechMK1

No no

You create them somewhere else

I will give you an example

Anne Batch

OK

MechMK1

0bin.net/paste/…

Here you see a very simple program

You see I make the function PrintName(string name) somewhere, and then call it inside Main()

Anne Batch

Ahh

Every method needs to be called inside _Main() ?

MechMK1

No, you can call methods in other methods

But when main ends, your program ends

Anne Batch

7:24 PM

Very good

Why didn't you use namespace

MechMK1

Namespaces make sense once your program grows

But for a simple example like I made, it's not necessary

Anne Batch

Indeed

MechMK1

It's like variable names. If you write a real program, then you want to make sure your variables have good names

But if you just write a tiny script, you can just call them whatever

Anne Batch

Great

Could you explain me the param string[]?

args

MechMK1

Yes, of course

Anne Batch

7:26 PM

Thanks

MechMK1

So have you ever used a console application?

One that uses text input instead of a nice window?

Anne Batch

Yes

MechMK1

Nice

So when you call something like cp, then you use it like cp file1 file2 file3 some/dest/dir

And the variable string[] args means it's a string array, of all the arguments that were supplied when starting the program

args[0] is the name of the program (in my example "cp")

args[1] would be "file1", args[2] would be "file2", args[3] would be "file3" and args[4] would be "some/dest/dir"

Anne Batch

I understood a little bit

It's confusing for me

Maybe I need to learn more

MechMK1

I will make a simple program to show you, okay?

Anne Batch

7:30 PM

Okay, that's good

MechMK1

0bin.net/paste/…

When you compile this, you will get a file like "ArgumentDemo.exe"

When you call it as "ArgumentDemo.exe 1 2 3 4" it will first print its name, then 1, 2, 3, 4

Anne Batch

I didn't understand so much, that's a new thing for me, it's complicated

But don't worry

MechMK1

It's okay, it will all make more sense in time

Anne Batch

Indeed

MechMK1

When I first learned about C#, our professor literally said "Don't worry about any of this stuff up here yet"

Anne Batch

7:39 PM

Perfect

I will listen to your professor haha

MechMK1

For now, the Console class will be pretty important to you

Since it allows you to print stuff, and read stuff from the console

Anne Batch

Console is a class?

MechMK1

Yes

Anne Batch

Let me see if I know

Console = a class

WriteLine = method

MechMK1

Correct

A method of the Console class

Anne Batch

7:41 PM

Ohhh that's good

C# uses .

Python also uses a dot

MechMK1

Yes

Anne Batch

Great

Let me try to write a script and show to you?

Actually a program

MechMK1

Sure thing

Anne Batch

C# writes program, not scripts, right?

pastebin.com/QgyG8mmW

Is it good?

MechMK1

Correct

Let me see

Anne Batch

7:50 PM

That's too much basic

MechMK1

It's good

And it's correct

Anne Batch

Great

I'll get out now to watch the video

MechMK1

Nice!

Anne Batch

I will be back after 2-3 hours, can we talk this time?

Bye see you hacker. Take care, thanks for helping :D

MechMK1

I hope we can, but I might be asleep already
