0-Day: aCROPalypse on Pixel and Windows devices.

[Dygear]

Summary

Cropping images on Windows and pixel devices will sometimes save the uncropped image, or remove other edits made to that image file. For sites that recompress the image, this is sometimes compresses away the crop part of the file, or makes it harder to read. But if sites do not re-compress the files that are uploaded to them then the uncropped area is available to see still. This effects Google's built in image editing tool on the Google Pixel, and also happens on Windows 11 with the Windows Snipping Tool.

My thoughts

Something like this happened back in ~2006 with a host from Call For Help on TechTV. Where a host of the show saved a picture of herself but the Photoshop PSD file saved the original thumbnail for the image. Unfortunately she distributed the file as part of a show segment not realize the meta data thumbnail was of the original picture.

Does this affect using something like Win+Shift+S to only screenshot part of the screen?
