I thought this might be useful for some people. Not all companies are very good and disclosing what been compromised during data breeches. Troy Hunt has developed a site which can cross-check your email address against all of the known data breeches and basically tell you if your account was compromised during any of these.

I found it rather useful, and he’s always adding more when he manages to get his hands on the data for any breeched website.
