🕵🏻 We found a way to identify scheduled post on LinkedIn. All you need is for the post to contain an image, video or other type of document.
● Extract upload date of image/video included into the post
● Extract the date and time of the post
● If the dates are very different, it is a scheduled post
● Extract upload date of image/video included into the post
● Extract the date and time of the post
● If the dates are very different, it is a scheduled post

We discovered a way to find out the date when a profile picture was last uploaded or edited:
● Right-click on the image
● Save the image
● Parse the filename into a Unix timestamp

🕵🏻 As OSINTers, we are constantly learning new methods of gathering and deriving additional information in different ways. It's always important to test the effectiveness and correctness of the technique on test data (i.e. a fake account) where you know what the expected result should be.
