Ask HN: Am I under attack?
https://news.ycombinator.com/item?id=11809463So, over the last month, I've received five "welcome to X" emails for relatively prominent online services.
Two of these were gaming related, and included a fairly unique username which I tracked to a redditor who claimed to have no idea what was going on, though they admitted they had an account with one of the gaming services.
It could be coincidence, I suppose, that someone has a similar email and keeps entering it wrong in the same way. It seems unlikely, but otherwise I'm not sure how signing up for services with my email address is an attack vector.
Is there a risk I am missing here?
