Spam Linked to Old Adobe Hack?

I got one of those 'we know your password and unless you pay up we'll publish your dodgy web activity' spam emails today, and it included the password I used for my Adobe account before that huge breach way back in 2013.

I obviously changed the password as soon as the hack was published, and my Adobe account is the only place I used that password, so in the very remote chance you are still using the same password for your Adobe account as from before that 2013 breach, I'd be very inlined to change it.
