Hackthebox stego challenges

Hack the Box Challenge: Art. June 27, Hint: Can you find the flag? Art as in the concept, or the name? Let's find out! I download the zip file using wget then extract is using unzip and the provided password. A PNG file? I type in xdg-open art. Oh that's pretty. Looks kind of like a maze with lots of pretty colors.

Ok… maybe the flag is hidden using steganography.

HackTheBox Remote Writeup (10.10.10.180)

The file size is 5. I should probably note at this point, that I am not very good at steganography - luckily there's Google and tools already written that work in Kali.

I managed to find two such tools: Steghide and StenoSuite. I'll start with StegoSuite first, so let's get that installed. I don't like installing a lot of things at once, I'd rather install one tool, use it first, and if it doesn't meet my needs, uninstall and try another one. I think this comes from my time as a computer tech many years ago.

During my troubleshooting days, I'd try one thing at a time trying to solve the problem. This way I could easily keep track of what was done to resolve the issue.

With Stegosuite installed, let's go straight to the man pages. Looks like it has a very intuitive GUI, so I launch it through the terminal by typing in stegosuite. I load the image file and click Extract. Well at first glance, there's nothing there. It looks like it locked up trying to find anything.

I went back to Hack the Box to double-check something.Ohh, a Substition Cipher. I noticed repeating words in the ciphertext. Skip to content. Branch: master. Create new file Find file History.

Nothing interesting here. Let's try stegsolve and use different bit planes.

Let's try! And we got something from steghide! Gur gerrf uryc perngr n fcrpvny raivebazrag juvpu, va ghea, nssrpgf gur xvaqf bs navznyf naq cynagf gung pna rkvfg va gur sberfg.

Decoding the ciphertext will gives us this message: The forest is a complex ecosystem consisting mainly of trees that buffer the earth and support a myriad of life forms.

The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest.

Trees are an important component of the environment. They clean the air, cool it on hot days, conserve heat at night, and act as excellent sound absorbers.

All you have to do is start a container and mount the steganography files you want to check. General screening tools Tools to run in the beginning. Allow you to get a broad idea of what you are dealing with. Tools detecting steganography Tools designed to detect steganography in files.

Mostly perform statistical tests. They will reveal hidden messages only in simple cases. However, they may provide hints what to look for if they find interesting irregularities. Tools actually doing steganography Tools you can use to hide messages and reveal them afterwards.

Some encrypt the messages before hiding them. If they do, they require a password. If you have a hint what kind of tool was used or what password might be right, try these tools. Some tools are supported by the brute force scripts available in this Docker image. Steganography GUI tools All tools below have graphical user interfaces and cannot be used through the command line. To run them, you must make an X11 server available inside the container.

Two ways are supported:. Alternatively, find other ways to make X11 available inside the container. Many different ways are possible e. Screening scripts Many tools above do not require interaction with a GUI. Therefore, you can easily automate some workflows to do basic screening of files potentially containing hidden messages.

Since the applicable tools differ by filet type, each file type has different scripts. For each file type, there are two kinds of scripts:.

Steganography examples The image contains a sample image and audio file each in different formats:. You can run the screening scripts to see if they find anything on them or try to break them otherwise. To run them, you must change that.After a challenge here you can create your login.

With the connection pack for openvpn it is possible to connect to the labs with a Kali machine or any other Linux I guesseasy. With the free account you can solve challenges and active machines.

Active machines For owning systems and users there are flags that are stored in files on the machines, for example:. The labs remind me about the OSCP labs, and lots of people are using them for training before the OSCP certification which might be a good idea, though I did not or to get an impression about the labs and the exam. I had a closer look at some boxes and solved one so far in a couple of hours.

The lab looks really fun, and I would recommend it for everyone who wants to train and learn hacking. Challenges The challenges also look quite good, i had a look but honestly, I am much more into owning. Here are the categories for the challenges:. For solving for example the Stego challenges, you download a file with a hidden message and have to find it.

I was surprised that there are also some Forensics challenges, I will defilnetly have a look into those too. Conclusion This is definetly a great playground for everyone who is into solving challenges and pwn boxes.

I am not sure if hackthebox is good for total beginners, there are no big explanations or tutorials for the machines or what is to do. With the VIP membership you also have the retired machines with walkthroughs. For your career hands-on and solving challenges is a very important part, so I recommend: sign up.

For each file type, there are two kinds of scripts:. Wordlist generation The brute forcing scripts above need wordlists. Imho it will very likely not help to use huge standard wordlists like rockyou. The scripts are too slow for it and stego challenges seem to not be designed for this. A more probable scenario is that you have a hunch what the password could be but you do not know exactly.

For these cases, several tools to generate wordlists are included:. Steganography examples The image contains a sample image and audio file each in different formats:. You can run the screening scripts to see if they find anything on them or try to break them otherwise. To run them, you must change that. What is required to do so depends on your host machine.

I searched for steg tool for wav and found this WavSteg. I just tried that tool to check if we could get something with 1 million bytes of data to recover from the wav file. Apparently, this requires the size in bytes of the hidden data to be accurate or the result may be too short or contain extraneous data. This tool executes a brute force attack with Steghide.

After that decoding process, we got an unreadable data but I suddenly noticed this familiar strings:. Skip to content. Branch: master. Create new file Find file History.
