JpegMedic ARWE is the "small brother" of JpegMedic, offering less manual control but full automation for this specific problem. It works on a simple principle: many ransomware variants corrupt the file's header and initial data but leave the actual graphical pixel data intact. The tool takes metadata (technical headers) from a known-good JPEG and grafts it onto the damaged file's data, effectively "re-wrapping" the image. The result is a viewable image, though it may be missing a few lines at the top.
