I've been getting those emails constantly at work for the past week or two. The first one freaked me out a little, because I recognized the password that they claimed I had used. It wasn't one I'd ever used for my email address, though.
I've been trying to figure out where they might have gotten that password from. I don't think I ever used FileFront with my work email address, but it may have been another cloud file service. (YouSendIt?)
Edit: Looks like the breach might have been from an old Adobe account, according to HaveIbeenpwned.
