The problem with homograph attacks is that the more we talk about them, the mode it gives ideas to frauders.
Note that it is also - and I believe this strongly - a super fantastic way for security providers to scare their clients reminding them to buy their services because if they don't, the world will collapse ;-)
Last May, I wrote (in a very limited english that only non-english speakers can understand) a post about it to explain what an homograph attack is.
This morning, I read a new updated post, written in words that even I understand: it is entitled "Homographs, Attack!": it explains homograph attacks in simple words with cool designs. This is a good read and this is something that operators of large domain name portfolios should read too.
