Ok, if it helps, I can shed a little light (20+ years in CyberSec) on how this is a threat even on a fun bbq site. I too, don’t mind if someone sees my pics, but thats not the issue.
Probably the most common or likely threat is your account being taken over, the risk being that they get your email and login info. Once they have that, they’re off to the races. Using a technique called credential stuffing, they will then go try your username or email and password at practically every site imaginable, especially financial or banking. Since many follks DONT use multiple passwords for their accounts, the likelihood that this works is pretty high. An using a botnet, they can run millions of these attempts in literally seconds. And they don’t even care if any individual attempt doesn’t work, becuase they run in such massive quantities that the rule of large numbers means that some will, with bad consequences.
Even getting your email exposes you to phising ttempts, because knowing bbq is a passion helps them design an appealing email that gets you to click on a malicious link.
So THANK YOU CHRIS for looking out for us, keep up the great work !!
