This is hardly new. I remember collecting ebooks on 4chan circa 2005 via this method. The fact that it was a jpg allowed you to post it on the imageboard with the zip/RAR file therein containing a txt/doc/rtf of the ebook.
- DavidBuchanan 8y agoAnd yet, nobody has done the same for Twitter until now. The difference is that twitter applies a series of operations to all uploaded image, stripping EXIF data, recompressing, etc., which would normally be difficult to work around.
- awirth 8y agoDid people do this back in the day? 4chan used to be totally fine with just uploading a jpeg concatenated with a zip, but I haven't seen this ICC profile trick before today.
- palunon 8y agoWell, 4chan served you the original file, so you didn't need to evade image processing at all
- lordcorvin1 8y ago4Chan actually strips EXIF data as well
- goatsi 8y agoThere is actually a greasemonkey script that lets you embed encrypted messages into pictures uploaded to imageboards, letting you carry on a side conversation this way. https://github.com/desudesutalk/desudesutalk/wiki/How-to-use-this-script https://github.com/desudesutalk/desudesutalk/wiki/How-to-use...

- code_duck 8y agoI recall discovering apparent image files that had a rar archive appended. Not sure if it’s the same method.
