It’s something called ADS (Alternate Data Stream) which you can see as some kind of second hidden file content. Browsers create an ADS with name Zone.Identifier when downloading a file and attach it to the downloaded file. The content of the ADS is the information where the file was downloaded from, i.e. the Zone (3 for Internet) and usually the URL.
Programs and Windows usually use the existence of the Zone.Identifier to show you a warning that a file was downloaded and may pose a risk to your system when opening/exexuting it.
I download a file on Linux, and it has data, a filename, and some permission metadata. That’s it. It sounds like this metadata layer deserves all of the hacks that will come for it.
What the hell is a “Mark of the Web”?
