It appears this IS a Scam attempt.

It looks like hackers have managed to get all customer info, AND have control of Cryptsy email server - as the sam email they sent out came from Cryptsy servers.

So while not an expert I would suggest changing your password on Crytpsy to a strong one, make sure 2FA is enabled, and not to act on ANY email received from Cryptsy - check their website directly for updates.
