A student recently asked me a pretty reasonable question: was there a precompiled Windows version of StegSeek?
We use StegSeek in a SEC587 lab, and they wanted a simpler way to run it. Download the executable, open a terminal, and get to work.
The original project points Windows users toward WSL. That works, but I understood the request. Sometimes you just want to run a tool against a file without setting up another environment first.
So I put together an unofficial native Windows build and published it on Argelius Labs’ GitHub.
There’s a little more behind why I wanted to do this.
For years, I mostly avoided talking about steganography in my courses. It’s an interesting subject, and hiding a message inside an image makes for a cool demonstration. But I kept running into the same problem: what useful thing could I give students to do with that information?
Telling someone that an ordinary image might contain hidden data is easy. Giving them a practical way to investigate that possibility is harder. I didn’t have enough good options I felt comfortable recommending.
I don’t want to send students home with another thing to worry about and no useful way to check it.
StegSeek gave me something concrete to work with.
StegSeek was created by Rick de Jager and is based on Stefan Hetzl’s Steghide. Those authors and the other contributors deserve the credit for the underlying tools. My contribution here is the Windows port, packaging, and instructions to make it easier to get running.
StegSeek can quickly try passwords from a wordlist against data hidden with Steghide. That’s useful, but the feature I really like is its ability to look for signs of Steghide data without already knowing the password.
Its seed mode searches the possible embedding patterns and can report a possible match, the size of the hidden data, and information about the encryption. If the data was embedded without encryption, it can even recover the contents without guessing the password.
That’s a pretty cool easy button to have.
I’m all for making an investigator’s life easier, but I want that button to do something useful. A scan that gives me confidence without a meaningful basis for it is basically a placebo. Here, there’s a specific technique being checked and a result I can follow up on.
There are limits, and they matter. StegSeek is checking for Steghide data. It doesn’t detect every possible way someone could hide information in a file. A possible match needs investigation, and finding nothing doesn’t prove that a file contains no hidden data. Encrypted contents still need the password or a successful password attack.
That’s a useful scope for a tool. I can explain what it checks, show students how to run it, and talk about what the results actually mean.
The Windows download includes the executable, a couple of demo images, and a tiny wordlist so you can try it immediately. You don’t need WSL, a compiler, or Python to run it. It’s still a command-line tool, so open it from PowerShell or a command prompt.
One detail worth calling out: if you don’t specify a wordlist, this Windows build looks for rockyou.txt in your terminal’s current directory.
The full RockYou list isn’t included in the download. There’s a link in the README, along with instructions for using your own wordlist. The matching source, build instructions, original credits, and licenses are available too.
You can download the Windows build here.
If you want to try it, start with the included examples. Seeing it find hidden data in a file you can test yourself is a good way to understand why I wanted students to have easier access to it.
