Obscure E-Mail Vulnerability
Schneier on Security
APRIL 9, 2018
This vulnerability is a result of an interaction between two different ways of handling e-mail addresses. Gmail ignores dots in addresses, so bruce.schneier@gmail.com is the same as bruceschneier@gmail.com is the same as b.r.u.c.e.schneier@gmail.com. (Note: I do not own any of those email addresses -- if they're even valid.) Netflix doesn't ignore dots, so those are all unique e-mail addresses and can each be used to register an account.
