Description

DC-3 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing.

As with the previous DC releases, this one is designed with beginners in mind, although this time around, there is only one flag, one entry point and no clues at all.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

For beginners, Google can be of great assistance, but you can always tweet me at @DCAU7 for assistance to get you going again. But take note: I won't give you the answer, instead, I'll give you an idea about how to move forward.

For those with experience doing CTF and Boot2Root challenges, this probably won't take you long at all (in fact, it could take you less than 20 minutes easily).

If that's the case, and if you want it to be a bit more of a challenge, you can always redo the challenge and explore other ways of gaining root and obtaining the flag.

Technical Information

DC-3 is a VirtualBox VM built on Ubuntu 32 bit, so there should be no issues running it on most PCs.

Please note: There was an issue reported with DC-3 not working with VMware Workstation. To get around that, I recommend using VirtualBox, however, I have created a separate DC-3 VMware edition for those who can only use VMware.

It is currently configured for Bridged Networking, however, this can be changed to suit your requirements. Networking is configured for DHCP.

Installation is simple - download it, unzip it, and then import it into VirtualBox and away you go.

Important

While there should be no problems using this VM, by downloading it, you accept full responsibility for any unintentional damage that this VM may cause.

In saying that, there shouldn't be any problems, but I feel the need to throw this out there just in case.

I'm also very interested in hearing how people go about solving these challenges, so if you're up for writing a walkthrough, please do so and send me a link, or alternatively, follow me on Twitter, and DM me (you can unfollow after you've DM'd me if you'd prefer).

DC-8 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing.

This challenge is a bit of a hybrid between being an actual challenge, and being a "proof of concept" as to whether two-factor authentication installed and configured on Linux can prevent the Linux server from being exploited.

The "proof of concept" portion of this challenge eventuated as a result of a question being asked about two-factor authentication and Linux on Twitter, and also due to a suggestion by @theart42.

The ultimate goal of this challenge is to bypass two-factor authentication, get root and to read the one and only flag.

You probably wouldn't even know that two-factor authentication was installed and configured unless you attempt to login via SSH, but it's definitely there and doing it's job.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

DC-6 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing.

This isn't an overly difficult challenge so should be great for beginners.

The ultimate goal of this challenge is to get root and to read the one and only flag.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

For beginners, Google can be of great assistance, but you can always tweet me at @DCAU7 for assistance to get you going again. But take note: I won't give you the answer, instead, I'll give you an idea about how to move forward.

Technical Information

DC-6 is a VirtualBox VM built on Debian 64 bit, but there shouldn't be any issues running it on most PCs.

I have tested this on VMWare Player, but if there are any issues running this VM in VMware, have a read through of this.

It is currently configured for Bridged Networking, however, this can be changed to suit your requirements. Networking is configured for DHCP.

Installation is simple - download it, unzip it, and then import it into VirtualBox or VMWare and away you go.

NOTE: You WILL need to edit your hosts file on your pentesting device so that it reads something like:

192.168.0.142 wordy

NOTE: I've used 192.168.0.142 as an example. You'll need to use your normal method to determine the IP address of the VM, and adapt accordingly.

This is VERY important.

And yes, it's another WordPress based VM (although only my second one).

Important

While there should be no problems using this VM, by downloading it, you accept full responsibility for any unintentional damage that this VM may cause.

In saying that, there shouldn't be any problems, but I feel the need to throw this out there just in case.

Clue

OK, this isn't really a clue as such, but more of some "we don't want to spend five years waiting for a certain process to finish" kind of advice for those who just want to get on with the job.

cat /usr/share/wordlists/rockyou.txt | grep k01 > passwords.txt That should save you a few years. ;-)

Description

DC-5 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing.

The plan was for DC-5 to kick it up a notch, so this might not be great for beginners, but should be ok for people with intermediate or better experience. Time will tell (as will feedback).

As far as I am aware, there is only one exploitable entry point to get in (there is no SSH either). This particular entry point may be quite hard to identify, but it is there. You need to look for something a little out of the ordinary (something that changes with a refresh of a page). This will hopefully provide some kind of idea as to what the vulnerability might involve.

And just for the record, there is no phpmailer exploit involved. :-)

The ultimate goal of this challenge is to get root and to read the one and only flag.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

For beginners, Google can be of great assistance, but you can always tweet me at @DCAU7 for assistance to get you going again. But take note: I won't give you the answer, instead, I'll give you an idea about how to move forward.

But if you're really, really stuck, you can watch this video which shows the first step.

DC-4 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing.

Unlike the previous DC releases, this one is designed primarily for beginners/intermediates. There is only one flag, but technically, multiple entry points and just like last time, no clues.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

For beginners, Google can be of great assistance, but you can always tweet me at @DCAU7 for assistance to get you going again. But take note: I won't give you the answer, instead, I'll give you an idea about how to move forward.

Description

Much like DC-1, DC-2 is another purposely built vulnerable lab for the purpose of gaining experience in the world of penetration testing.

As with the original DC-1, it's designed with beginners in mind.

Linux skills and familiarity with the Linux command line are a must, as is some experience with basic penetration testing tools.

Just like with DC-1, there are five flags including the final flag.

And again, just like with DC-1, the flags are important for beginners, but not so important for those who have experience.

In short, the only flag that really counts, is the final flag.

For beginners, Google is your friend. Well, apart from all the privacy concerns etc etc.

I haven't explored all the ways to achieve root, as I scrapped the previous version I had been working on, and started completely fresh apart from the base OS install.

Technical Information

DC-2 is a VirtualBox VM built on Debian 32 bit, so there should be no issues running it on most PCs.

While I haven't tested it within a VMware environment, it should also work.

It is currently configured for Bridged Networking, however, this can be changed to suit your requirements. Networking is configured for DHCP.

Installation is simple - download it, unzip it, and then import it into VirtualBox and away you go.

Please note that you will need to set the hosts file on your pentesting device to something like:

192.168.0.145 dc-2

Obviously, replace 192.168.0.145 with the actual IP address of DC-2.

It will make life a whole lot simpler (and a certain CMS may not work without it).

If you're not sure how to do this, instructions are here.

Important

While there should be no problems using this VM, by downloading it, you accept full responsibility for any unintentional damage that this VM may cause.

In saying that, there shouldn't be any problems, but I feel the need to throw this out there just in case.

Description

DC-1 is a purposely built vulnerable lab for the purpose of gaining experience in the world of penetration testing.

It was designed to be a challenge for beginners, but just how easy it is will depend on your skills and knowledge, and your ability to learn.

To successfully complete this challenge, you will require Linux skills, familiarity with the Linux command line and experience with basic penetration testing tools, such as the tools that can be found on Kali Linux, or Parrot Security OS.

There are multiple ways of gaining root, however, I have included some flags which contain clues for beginners.

There are five flags in total, but the ultimate goal is to find and read the flag in root's home directory. You don't even need to be root to do this, however, you will require root privileges.

Depending on your skill level, you may be able to skip finding most of these flags and go straight for root.

Beginners may encounter challenges that they have never come across previously, but a Google search should be all that is required to obtain the information required to complete this challenge.
