A small intro how to host pwn ctf challs in Docker via AWS EC2 Instance

File Structure

AWS EC2 configure

Step 1

1. Create an Instance in aws , in security tab , click on inbound rules , there add custom TCP check box & add the custom port you want to host it on to

Step 2

2. login to your instance , & install docker & start the docker service

$ sudo apt-get update
$ sudo apt-get install docker.io
$ sudo systemctl start docker

Step 3

once everything is done , now build the Docker container & run it in background mode

$ docker build -t binexp .
$ docker images
$ docker run -d -it --rm -p 1337:1337 binexp 

Step 4

test & connect to the port using nc & see if everything is working or not

so the chall seems working on our intended Port

Lets try to exploit & see if something crashes or not

we will run our exploit against the intended port & our instance IP , so lets see

Exploit

Bingo !! It works fine

Happy Hacking <3
