0.1. Instaling Docker

Just Begin whit the networking of dockers

1. List available networks

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker network ls
NETWORK ID     NAME      DRIVER    SCOPE
f9b24ce95506   bridge    bridge    local
51d655520585   host      host      local
d8713935ea94   none      null      local

2. View the most relevant information of the "bridge" network

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker network inspect bridge
[
    {
        "Name": "bridge",
        "Id": "f9b24ce955067fa526360e91951674d9cc16de73917d079470587272c6f0127c",
        "Created": "2022-08-01T17:13:17.266757822-04:00",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16",
                    "Gateway": "172.17.0.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": false,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,
        "Containers": {},
        "Options": {

            "com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
            "com.docker.network.bridge.name": "docker0",
            "com.docker.network.driver.mtu": "1500"
        },
        "Labels": {}
    }
]

3. Install kali image

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$ docker pull kalilinux/kali-rolling
Using default tag: latest
latest: Pulling from kalilinux/kali-rolling
c44a5498bf98: Pull complete
Digest: sha256:f2ed86a0504055c6920915decc2be75cc3ecc836b255bb0a34263a7e39cfb24f
Status: Downloaded newer image for kalilinux/kali-rolling:latest
docker.io/kalilinux/kali-rolling:latest

4. Create a container based on the kali image and access it.

NOTE: To identify the containers, we give a name to each one of them during the execution, in this case we will call it "Container_Kali":

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker run -ti --name Container_Kali kalilinux/kali-rolling /bin/bash
┌──(root㉿ba54ccb86aeb)-[/]
└─# uname -a
Linux ba54ccb86aeb 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6 (2022-07-07) x86_64 GNU/Linux

5. Upgrade kali

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$sudo apt update && apt dist-upgrade
┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$sudo apt autoremove & apt clean

6. Installing packages to Kali

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$apt install kali-tools-top10 #Install the top 10 kali apps

NOTE: To install more packages and binaries here

7. List containers

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker container ls -a
CONTAINER ID   IMAGE                    COMMAND       CREATED          STATUS                       PORTS     NAMES
ba54ccb86aeb   kalilinux/kali-rolling   "/bin/bash"   14 minutes ago   Exited (127) 5 seconds ago             Container_Kali

8. Start the container (using the name)

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker start Container_Kali
Container_Kali

9. Enter the container

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker exec -it Container_Kali /bin/bash
┌──(root㉿ba54ccb86aeb)-[/]
└─#

10. Save the updated and customized image

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker commit Container_Kali imagen-kali
sha256:b5bb0ecd3c673411638e8c7588b455ef7a914ec73de7e4d3d60d259987eb97f8

10.1. You can save the image to export it and use it again in another station with docker, using the following command

┌──(leonuz㉿sniperhack)-[~/DOCKER-IMG] # let's first go to where we want the image to be stored
└─$ docker save -o kali-top10.tar imagen-kali
┌──(leonuz㉿sniperhack)-[~/DOCKER-IMG]
└─$ ls -la
total 3552068
drwxr-xr-x  2 leonuz leonuz       4096 Aug  1 18:13 .
drwxr-xr-x 50 leonuz leonuz       4096 Aug  1 18:12 ..
-rw-------  1 leonuz leonuz 3637301760 Aug  1 18:13 kali-top10.tar

10.2 To load the image saved on disk, we use the following:

┌──(leonuz㉿sniperhack)-[~/DOCKER-IMG]
└─$ docker load -i  kali-top10.tar
Loaded image: imagen-kali:latest

11. Run the container (with all updates and applications installed)

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker run -ti imagen-kali /bin/bash

12. Install images of vulnerable machines

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$ docker pull bkimminich/juice-shop
Using default tag: latest
latest: Pulling from bkimminich/juice-shop
Digest: sha256:35fce029db378b200a92dbdb1587100d562458637fc776ff85e713e0ef793000
Status: Image is up to date for bkimminich/juice-shop:latest
docker.io/bkimminich/juice-shop:latest

12.1. Leave in background running the Container_Juice_Shop:

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$ docker run -d -p 3000:3000 --name Container_Juice_Shop bkimminich/juice-shop
09c91a7efcaab6b973dda8c56015bf34c121fe2ad2b6132e37e1a2b109240db5

12.2. Install the other vulnerable image (Security-Ninja):

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$ docker pull opendns/security-ninjas
Using default tag: latest

Image docker.io/opendns/security-ninjas:latest uses outdated schema1 manifest format. Please upgrade to a schema2 image for better future compatibility. More information at https://docs.docker.com/registry/spec/deprecated-schema-v1/

12.3. Leave in background running the Container_Security_Ninjas:

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$ docker run -d -p 8899:80 --name Container_Security_Ninjas opendns/security-ninjas

13. To see the IP address of a container, we can view it from Docker with the command "docker inspect" and the container name

14. by filtering the response to the above command we can search according to what we need. e.g. dir IP

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' Container_Juice_Shop
172.17.0.3

15. if we want to start over and delete all images and containers, use the following commands

┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker container stop $(docker container ls -a -q)
┌──(leonuz㉿sniperhack)-[~/Pentest-Lab]
└─$docker system prune -a

16. With this information we can now begin to find and exploit vulnerabilities.

by leonuz Beginner&apos;s Luck Challenge Description My sister&#x2019;s computer crashed. We were very fortunate to recover this memory dump. Your job is get all her important files from the system. From what we remember, we suddenly saw a black window pop up with some thing being executed. When the crash happened, she was trying to draw something. Thats all we remember from the time of crash. Note: This challenge is composed of 3 flags. Challenge file: MemLabs_Lab1 We start for identify the operating system, for that we use imageinfo plugin.

I have no idea on how to recover it. The only evidence we have, at this point of time is this memory dump. Please help me. Note: This challenge is composed of only 1 flag. The flag format for this lab is: inctf{s0me_l33t_Str1ng}
