Credit Card Scammers CTF

This is my first Capture the Flag exercise and covers a number of different techniques.

The back story: Scammers are taking advantage of people and various fake shopping websites have been setup, but people are finding their orders never arrive. We have identified one scam website which we believe is harvesting credit card details from victims. Your objective is to take down the scam website by gaining root access, and identify the 3 flags on their server. Our intelligence suggests the scammers are actively reviewing all orders to quickly make use of the credit card information.

The types of vulnerability used in this CTF can be seen below (they are intentionally hidden by default):

You can download the Capture the Flag here. This has been tested using VirtualBox but may work with other virtualisation platforms. DHCP is enabled, and it is recommended you run this in host-only network mode.

Please feel free to leave me feedback in the comments. I am keen to see what people thought about it and how easy/difficult they thought it was.

Hi. Thanks for your comment.

The default setting on the CTF is host-only. Do you have a host-only network setup on VirtualBox? If not, it may have changed back to NAT automatically as it can’t find a host-only network. NAT isn’t needed for this box. If you follow the steps on my other post up to the first two screenshots, it will show you how to enable host-only network if you haven’t done so already.

Let me know if you need any help. Thanks

Hi,
With virtualbox 6 and the Credit-Card-Scammers.ova file (md5: e0af2231b6cc0bba6b78340b79a74885) provided on vulnhub, the VM has two network interfaces by default. Is this normal?
My vbox configuration has only one host-only network. So the second interface of the vm is self-configured in nat (or bridged).
Have a good day
Vincent
