Cheaters Will Never Be Welcome in Dota

Today, we permanently banned over 40,000 accounts that were using third-party software to cheat in Dota over the last few weeks. This software was able to access information used internally by the Dota client that wasn't visible during normal gameplay, giving the cheater an unfair advantage. While fixing the underlying issues that made these che...

07:33

Interesting

Is it about knowing if you are visible to the enemy or not? @Ryozuki

08:51

Yea that was or still is a thing

Idk

08:53

Obv they wont tell

I mean they tell something

08:56

That they reserved memory space for the process that doesn't get read. And detected something reading from that memory region. (edited)

08:57

Which implies AoB scanning. (looping through the whole process to find a byte pattern) Because I see no other reason to read from memory addresses that you didn't explicitly hardcoded. (edited)

09:00

Another thing that should be common sense if you are familiar with how they detect stuff is that it must be an usermode application

So I did my research based on my amazing detective skills and found this project that is using a pattern scanner aka. AoB scanner https://github.com/SK68-ph/Overlay/tree/3.0/Dota2Overlay-3.0 one reply posted today https://www.unknowncheats.me/forum/3686236-post615.html seems to confirm it (though you never know what else the cheaters used claiming something is detected)

what does AoB stand for?

default

Is it about knowing if you are visible to the enemy or not? @Ryozuki

So yes. Players that used the tool that tells you if you are visible to enemy or not got banned for a long time.

have you ever worked with a terminal/console?

Patiga

have you ever worked with a terminal/console?

Not really

for what do you want to use the bot btw?

2. Step | I click on the https://discord.com/developers/applications link and create an app.

Discord Developer Portal — API Docs for Bots and Developers

Integrate your service with Discord — whether it's a bot or a game or whatever your wildest imagination can come up with.

Patiga

for what do you want to use the bot btw?

For my own custom ddnet server

10:42

but what should the bot do in that channel?

10:42

ist it about the $profile command?

No, like submit maps etc...

10:43

$ready

10:43

$release

oh okay

and automatically put in my server

10:43

Is that what it does right?

that will require setup way beyond what I did with the discordbot

damn currently checking spf and dmarc records over 228449808 domain names giga_chad

giga_chad

I think ddnet is in

I'm not sure if it is realistic for you to set it up, but I can go through the steps with you note that in the steps, we explicitly turn off that functionality ^^

10:45

step 2 looks good tho, got the token?

If i share the token what will happen?

that person can control the bot in any way they like

10:45

dont share it

Patiga

I'm not sure if it is realistic for you to set it up, but I can go through the steps with you note that in the steps, we explicitly turn off that functionality ^^

that would require some knowledge yea. he wants to have his own ddnet it seems like.

10:49

Bot Tab

oh my bad i didnt add the bot yet but i did now.

Image attachment

10:50

you should have a generate token button

Yes i have the token now

but I phrase it like that. even if we guide you through the instructions. you want something completely different.

still step 2 | turn on this two

Image attachment

10:52

and copy the token

yes that needs to be emphasized, of the entire infrastructure you casually mentioned that you want to set up, the discordbot might be the easiest

3. Step | Go back to the source file see on the 1. picture, and create a copy of the file on the 2. picture and name it as "config.ini" (edited)

Image attachment

Image attachment

if you don't mind sharing, for what purpose do you want to replicate the ddnet infrastructure? I don't have anything against a new server group, but if that is your goal, be warned that this is a big undertaking

deen got depressed and nearly gave up ^^

Well this server just should be for my little community

10:56

Friends and random invited peoples

then I suggest you approve the maps manually

10:56

i think you can config your own server to only pick maps from your own map pool

I don't think you need a map testing setup if its just for a small group of people you mostly trust

Thats way too long :/

yea but what do you think the bot does

This bot would make it more easly

not really

10:57

the map testers get pinged (maybe) and get the map file

10:57

they still have to manually approve it

i would get tired of editing the channels and download and delete the maps always

then figure out a concept that fits your needs and doesn't require you to be somewhat talented with computers

you could automate that small part of the process. I think the ddnet setup is very much overkill for your purpose

10:59

you probably only need a script that takes a map, copies it to the server

10:59

and maybe another one that copies it from the testing server to the 'actual' server

something like that

10:59

the discord bot is filled with so much more functionality

11:00

and the things you want from it get disabled with the provided instructions

So that what you all mean like its ain't possible?

it is

11:01

but I don't think you can make the bot do what you want it to do without help

11:01

also would be better to just make your own discord bot at that point

11:01

the one in the ddnet org is outdated (deprecated packages) and gets updated atm (edited)

So what would i get if i go through on the steps?

the commands that rely on the website api

11:02

#bot-cmds

it is beyond our knowledge how to set up the infrastructure you mentioned. what you actually need is a tiny portion of that infrastructure. your use-case sounds like it would be easier manually or with some minor scripts (or maybe a small own discord bot)

trust the stone

1

Raks

So what would i get if i go through on the steps?

you will actually get the testing commands, but only the discord portion of it. the thing you actually need of it, $ready, $release and the initial upload to the testing servers, will require much more steup

just do a small discord bot that listens to a channel & wait for any file, then just download it using requests (if u like python cuz javascript sucks) lib and done

And how can i make a bot like that or i really have to learn that?

chatgpt

11:06

ez

11:06

giga_chad

Programming experience would be beneficial

11:07

but you can paste something together with whatever the internet throws at you

ReiTW

chatgpt

Is that thing will help me automatically edit the channels?

11:08

by commands

that thing will help u to make some code, with a probability that it throws you some garbage code also

Ahw

And care with auto uploading to the test-servers, people will abuse it & upload a ton of bs. So let your testers react with an emoji to any file & then upload it to the server

ReiTW

that thing will help u to make some code, with a probability that it throws you some garbage code also

like this, for example

nodejs sux

@Raks maybe just do some simple python script like that: import discord from discord.ext import commands bot = commands.Bot(command_prefix= '!', intents=discord.Intents.all()) save_path = 'Desktop/server/data/maps' @bot.command() async def save_file(ctx, *, file: discord.Attachment): try: await file.save(save_path + file.filename) except Execption as e: #print error message print(e) await ctx.send('An error occurred while saving the file..') else: await ctx.send(f'File saved') client.run(BOT_TOKEN)

ReiTW

nodejs sux

that's C#

default

that's C#

is it lol? C# has var keyword?

yes

@Raks if there is only ur friends in the server its safe to use

but its not like javascripts var

looks ugly

once a type was assigned to it (it takes any for the first time)

11:14

you can only assign the same type after that

itube

@Raks maybe just do some simple python script like that: import discord from discord.ext import commands bot = commands.Bot(command_prefix= '!', intents=discord.Intents.all()) save_path = 'Desktop/server/data/maps' @bot.command() async def save_file(ctx, *, file: discord.Attachment): try: await file.save(save_path + file.filename) except Execption as e: #print error message print(e) await ctx.send('An error occurred while saving the file..') else: await ctx.send(f'File saved') client.run(BOT_TOKEN)

i dont even know where to make this ahh

for "any type" you have to use generics

I downloaded python but (edited)

also known as that <T>

Raks

i dont even know where to make this ahh

create a file called "maps.py" and paste that script in, change it to ur bot token and put the right 'maps' path

ReiTW

looks ugly

you hate it, you love it

Raks

i dont even know where to make this ahh

Best way to start is setting up your development environment. Use any editor as you like, Visual Studio, Visual Studio Code, Notepad etc etc etc. personally i'd recommend using a code editor with proper syntax highlighting, this will help you so much

i have notepad++ and Visual studios either

Raks

i have notepad++ and Visual studios either

Fair enough, do you wanna run it 24/7 or just when you're online?

if u want to do a discord bot its better to learn the basics of python or javascript @Raks

Then your local computer is fine

Create a folder on your desktop or <insert path you like> to keep things clean

yes best bots))

Open thy python then?

You can open the "maps.py" now

Not the console

When i double click on the maps.py it just flash up and gone

Yep, thats why you need to open the folder/file with "Open with Visual Studio"

create role "Mapper". change bot token and set the correct path

i think you also have to explain to him how to get the discord package using npm before you just give him the code that crashed before for him already (edited)

its avo's job

its your code

excuse me?

eh

should i create a repo

and put a readme

do whatever you want

12:03

but if you won't even give them the proper instructions on how to use your code

how to add the folder for save?

@Jupstar ✪ maybe u know this

15:05

u know how to declare a _ExtInt(N) literal that has more than the max literal value allowed?

15:05

_ExtInt(300) prime = 999999999999999999999999999999999;

15:06

_ExtInt is a clang extension, it does the same that _BitInt(N) does (standarized in c++23, but the extension from clang is available before)

15:06

i know u can get it doing bit shift and cast shenaningans but thats godly awful

15:07

error: integer literal is too large to be represented in any integer type

15:07

stupid

i mean that number is obviously bigger than the upper limit

no

no?

its not bigger than a 300bit integer lol

15:07

u dont understand the issue here

-2,147,483,648 to 2,147,483,647

15:08

oh 300bit

_ExtInt (_BitInt in c++23) allows declaring ints of n bits

doesn't seem to work as intended

https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2709.pdf

15:09

im sure i need to add some suffix to the literal

15:09

but idk which

15:09

i tried 999999999999999999999999999999999_ExtInt300

15:09

but no

I mean this is convincing:

The error message you are seeing is because the integer literal "999999999999999999999999999999999" is too large to be represented by any integer type. In C++, the largest integer type is typically "long long int", which can represent integers up to 9,223,372,036,854,775,807.

15:10

it suggested a library

15:10

but thats not what you want

nah i wanted it natively

15:13

and in clang cuz llvm

15:13

wanted to know if there is a bug with big int division

is GMP part of the windows api?

15:15

c++
#include <gmpxx.h>
using namespace std;

int main() {
    mpz_class prime = "999999999999999999999999999999999";
    cout << prime << endl;
    return 0;
}

15:15

ah no

15:17

__int128 is a thing but that isn't supported everywhere and requires you to compile using MSVC

c++
#include <iostream>
using namespace std;

int main() {
    __int128 prime = 999999999999999999999999999999999;
    cout << prime << endl;
    return 0;
}

(edited)

15:22

Yea I only find libraries that implement a big int datatype, no clue what your original plan was using bitshift. The problem with n-bit integers is that you have to assign the value to it. And that arbitrary value can't be represented by C++ itself. Even if the bits could logically speaking properly store that value. (edited)

I'd say u need a postfix literal

15:41

Smth like 9999_extint

15:44

Or create it from a string

15:47

Or find a multiplication that results in Ur value and multiple them: 99999LL * 111111111LL

yeah i mean this isn’t impossible by any means

Jupstar ✪

Smth like 9999_extint

ye but i dont know which

Ryozuki

ye but i dont know which

U can create an literal operator yourself if clang doesn't provide one

cant you initialize it from string translated at compile time, or directly byte array?

r u creating the next cookie clicker, or what do u even need 300bits for xd

nah

finite field arithmetic

17:29

was just testing something

its ok its just more combinations than atoms in the universe

17:30

and my target fps for ddnet

xd

hey so I'm using the OnWindowResize member of the CComponent class to update my width & height values that are used in the rendering function

18:05

refactoring some stuff

18:05

and this is happening for some reason but only when i'm pressing tab

Image attachment

18:05

it's like cropped but keeping the same aspect ratio

18:06

this does not happen when i update the values each time it's rendered

18:06

if you can't see it's messing up the map/transformation and the bar is really small in the corner

18:07

oh it's Graphics()->MapScreen(0.0f, 0.0f, m_Width, m_Height); specifically that's the issue. wut?

other components call that function too

oh i didn't realize it was a global thing i guess

18:08

but that makes sense

Ryozuki

was just testing something

I like python for finite fields

heinrich5991

I like python for finite fields

yeah it works nice cuz inf integer

18:17

but im doing this with llvm ir xd

0 * inf

you can also easily get the inverse in python:

18:24

pow(2, -1, 3)

Ryozuki

_ExtInt(300) prime = 999999999999999999999999999999999;

I wonder if something like _ExtInt(300) prime = std::numeric_limits<decltype(prime)>::max() might work

18:39

Oh you wanted sth else, I misread it as you wanting to initialize to the max

nah xd

18:42

i want a literal

18:42

that is bigger than long long

18:43

anyway im not touching c++ more

18:43

i just wanted to confirm if division worked correctly on llvm-ir with big integers

18:43

and it does from my tests

Yeah, I just took a quick glance at the standard and it doesn't seem really possible unless clang also added a suffix themselves

source_filename = "root"

declare i32 @printf(ptr, ...)

define i32 @print(i1 %0) {
entry:
  %prefix = alloca [4 x i8], align 1
  store [4 x i8] c"%d\0A\00", ptr %prefix, align 1
  %printed_characters_n = call i32 (ptr, ...) @printf(ptr %prefix, i1 %0)
  ret i32 %printed_characters_n
}

define i32 @main() {
entry:
  %s = sdiv i500 2457975212345678912345678923456723456789, 3
  %x = icmp eq i500 %s, 819325070781892970781892974485574485596
  %p = call i32 @print(i1 %x)
  ret i32 %p
}

18:44

this prints 1

18:44

so its correct the division

18:44

i got the division result with python

18:45

(i made up the first number)

Why are you writing llvm ir btw? finally making your own language?

i am

18:45

at work

18:45

but soon also for myself

18:45

xd

18:46

doing this at work makes me itch to do my own lang

Do JVM bytecode instead

nah

18:46

llvm is awesome

18:46

mlir looks promising too

Corporations love Java, you'll get big points with your boss

my boss hates java

18:46

and haskell

Fake corpo

likes erlang, rust, elixir

18:47

julia

Are you generating the IR by hand btw? I saw a cute library to work with it a couple weeks ago

im using inkwell

18:47

it makes u write llvm correctly

18:47

also rly useful to learn llvm

18:48

https://crates.io/crates/inkwell

18:48

do note that big int operations like im doing are only supported from llvm 16

How to get the log of core dump of ddnet server? Using ubuntu 22.04.1 LTS with systemd

How to get the log of core dump of ddnet server? Using ubuntu 22.04.1 LTS with systemd

log of core dump?

core dump sry

But what do you want to do? Open it in gdb? send it to someone?

18:50

With systemd coredumpctl collects all the dumps

see why the server crashed

coredumpctl list to find the dump

Ok thanks. I didn't have the coredumpctl installed though. If it crashed again I should be able to see the dump though, right?

@Learath2 i can say im a level above ur C chadness by doing llvm ir

18:51

BASEDDEPT

Mr.Gh0s7

Ok thanks. I didn't have the coredumpctl installed though. If it crashed again I should be able to see the dump though, right?

iiii don't know what systemd does, didn't even know it was possible to have coredumpctl not installed

btw the division from that code outputs 50k instructions xD

Mr.Gh0s7

you can try cat /proc/sys/kernel/core_pattern to see where the cores go

Ryozuki

50k? seriously?

its a rly high bit count

Learath2

you can try cat /proc/sys/kernel/core_pattern to see where the cores go

|/lib/systemd/systemd-coredump %P %u %g %s %t <number> %h

well thats what the t ool says

Maybe it's 400 instructions times 100 iterations?

I guess

looks highly unoptimized though

its not run through any optimizer

i know the cstring thing is probs wrong

20:07

also this is not the ddnet client

20:07

ive been fooled

could be an env thing on my end but tbh i couldn't be bothered to play with that & it's technically right because it was erroring saying strlen wasn't a defined symbol

20:07

yeah ik

20:07

i mean

20:07

i would happily port to ddnet cuz it's a small feature. but would it be welcome? that's what i'm asking (edited)

20:07

want to ask before submitting pr and spending time on that

i dont rly like it but u should hear others

looks like start of ddOS

what
