StegSpy is specifically tuned to detect files processed by five popular steganography tools:
You can find the tool hosted on Assembla's Steganography Project or archived on community platforms like SourceForge .
For example, a program called appends the ASCII code "CDN" to the end of the carrier file. StegSpy has a library of such signatures. By matching a suspect file against this library, it can not only confirm the presence of hidden data but also identify which program was used to hide it. It then reports the exact location within the file where the hidden content begins.
For maximum safety, run Stegspy inside a virtual machine (like VirtualBox) or within the built-in Windows Sandbox. This isolates the tool from your primary operating system. Alternatives to Stegspy

Developed by Bill Englehardt and first introduced around 2004, StegSpy is a signature analysis program for Windows. Rather than trying to break the complex encryption that might protect a hidden message, StegSpy looks for "fingerprints." It works on the observation that many steganography tools leave behind a unique signature or string of characters in the file where they hide data.
When a hidden file is detected, StegSpy reports the exact offset (marker position) where the payload begins. This numerical marker is fully compatible with standard hex editors like WinHex, allowing investigators to jump directly to the suspicious data segment without scanning the entire file.
StegSpy is "abandonware." The original developer has long since ceased updates, and official websites hosting the legitimate executable are offline.
