As @Starbuck@lemmy.world stated. They’re still valid image files, they just have extra data.

Hi db0, if I could make an additional suggestion.

Add detection of additional content appended or attached to media files. Pict-rs does not reprocess all media types on upload and it’s not hard to attach an entire .zip file or other media within an image (https://wiki.linuxquestions.org/wiki/Embed_a_zip_file_into_an_image)

Launchdarkly is likely a culprit as well. Just doing a background search reveals that the service allows dev teams to do A/B testing, enable new features without releasing a new version, and various other “dynamic” functions.

OP is on the wrong side of Occam’s razor
