A researcher has embedded the complete works of William Shakespeare in an image that he has distributed on Twitter. From the file, even the thumbnail image, the embedded file containing the works can be accessed. Embedding hidden information and messages inside objects or images that are not secret is known as steganography and allows the distribution of material in files that would otherwise not fall under scrutiny. While the researcher said that the method would likely not be effective as a malware distribution channel, it could provide a highly effective method of distributing files and methods covertly, or “hiding in plain sight.” If widely developed and used by criminal actors or terrorists, it has the potential to become a national security threat.
