  • A common attack is to replace one character with a similar character, say a 1 (one) for an l (ell) or a Turkish e for a Latin e. Most users will not be able to recognize the changes and will assume the site is one that is familiar to them.

  • The current trust system for SSL certificates is not as good as it may seem. Google has discovered serveral problems with the trust hierarchy.
