We have previously talked about LinkedIn having an endpoint for Outlook profile cards. This endpoint is receiving email addresses as input and returns the complete profile information (name, company, location, etc.). These sorts of APIs can be abused for OSINT.
To reproduce the set-by-step tutorial your will need an Outlook account (@hotmail.com, @live.com or outlook.com email), the latest version of ZAP and our WebSocket plugin.

Linking your Outlook profile to LinkedIn
Grabbing a valid session token
Linking both Outlook and LinkedIn profile will grant you a Bearer token. This token will not be refreshed frequently. To see this token you will need ZAP and our WebSocket decoding plugin. It is available for download at : https://github.com/GoSecure/zap-autodecode-view/releases/tag/version-1.0.0
Automating profile queries
Place the emails you want to test in a file. We will call it “email_list.txt”. Keep in mind that there is limit of approximately 1000 emails queries per day per LinkedIn account (token).
Next, you need to obtain a copy of the proof-of-concept script at https://github.com/GoSecure/linkedin-osint.
Executing the tool will look like this:
> cat email_list.txt
