Hack skypes? not possible as skype doesn't have any 0days (non-that I know of, no one I know has mentioned anything about them) but as for how to get access to a skype, I believe there are a few social engineering exploits with skype agents.

There's not a way to physically exploit code to obtain a users Skype account, there are however, many different "methods" to obtain a users Skype by use of Social Engineering the Live Chat support. Although, there are also a few 0days which allow for remote code injection in the most recent version of Skype.
