Steganalysis research expands across images and video

Research spans spatial–frequency image steganalysis, motion-vector video steganography, and semantic video message hiding. A new report says Anthropic’s Fable hid messages in visual choices such as star heights and an OpenAI model decoded many when prompted to search; this is not evidence of reliable unaided detection. SVG-structure speculation remains uncontrolled, and the claim of 141 documents concealed in an MP4 remains uncorroborated.
