If you use Roku...

Change your password.

Hackers got into 15,363 Roku accounts through credential stuffing.

Stuffing is when hackers steal user names and passwords from a web site(s), and just crunch the data at other sites until they get into accounts at more sites.

Bottom line: Don't reuse same user name/password combos because you never know which site will get hacked next and then your name/password combo is stuffed in at lots of other sites looking for access to more of your accounts.
