I was targeted by a similar recruiting scam several years ago -- again, a smallish company which was high on my interest list, with a personalized email matching my stated skills and experience.

All I can say is that while legit "cold" recruiting outreach happens all the time, if you are a job seeker take the time to verify these contacts. Don't give out personal or contact information until you are absolutely sure you know who you are talking to! A professional will not mind you taking this extra step.
