Confirmed, Walmart runs on Linux, and their promotional photo stream is in a folder called

/walmart/teaser

Time to use maltego.

How can u tell its linux?

@sovietspy2 It actually shows an error message so that rules out OSX, and its not prompting for any updates so it isn't Windows either :P

@corjaantje windows' defination of error is "something Happened".

@matsaki95 windows uses backslashes ;)

C:\bla\bla

It could possibly be a weird Mac configuration, but Mac typically doesn't allow you to modify root directories, so It would look like (I don't know the file structure of a Mac, this is pseudofiles):

/usr/walmart/programs/teaser

On a side note, pseudofiles sounds like something you'd go to jail for. Perhaps that's not a great word.

@matsaki95 It's easy! Backslashes face backwards: \

Forward slashes face forwards: /

It COULD just be a 403 error in a web browser. Lots of these things are just web browsers pointing at stuff.

I hate to respond to a rant this old, but do you remember if this was on a customer facing screen on a POS register?

@bkwilliams I don't remember
