No, your account wasn't hacked.  You fell for a very common scam on the Internet.  You clicked something that you shouldn't have and then in this case you ignored a warning message. 

Nobody can take L$ from your account without your permission.  As soon as you clicked the mandatory box that asked whether you wanted to give permission to debit your account, though, that's exactly what you agreed to.  There's no way to get the money back now.  It will show up in your Transaction History as a gift to that individual.  Try submitting an Abuse Report with all the factual information you have at hand, but don't expect miracles.  And next time, pay attention to what you click.

I think it's more likely, given the url in your question, that you were taken to a fake secondlife website where you entered your user name and password, which were then used to access your account and gift your lindens to the thief.  

This is a common scam.  

If you have not already done so you should immediately change your password, or your account will still be vulnerable, not only to theft, but also it will be used to scam other avatars in the same way, which will lead to no end of problems when YOU are reported as the scammer, since it will be your account that is used.
