Today the antispam tool in the company I work for blocked several emails. It has been months since last time, so I took the time to analyze the quarantined messages.
Since I almost never give my corporate email to outside parties, it is very strange, but last year I participated in an online webinar and since I was watching it at work I used the corporate email.
And the messages seem to be related to the subject of the webinar, what leads me to think the database at the company that held the webinar has been leaked.
Searching google for recent events did not give any news of the leak.
What steps should I do regarding this possible database leak? To protect myself and/or to report the leak in an useful way?
