Or assume it's a scam and ignore

Do you have an account with STM microelectronics?

If not, then it is a scam. If yes and you used a link in the original email, then it's a scam as Emgee has explained.

If you have passed your details to a fake site, particularly if you use only one password for multiple sites, like many do, then change your other passwords, now!

If you do have an account with STM microelectronics and they have your credit card details, might be worth contacting your card company and canceling the card.

This may be mere coincidence … but I wonder if the various ‘Information Commissioners’ have prompted them to tidy-up the databases:

A recent eMail from Sony Europe reads …

Different style, but maybe the same underlying ‘process’

Hmmm.

Makes me wonder about an e-post this morning supposedly from "no-reply [at] dropbox.com" , starting "Dear Nigel"  (a bit familiar for a business correspondence, isn't it?) and notifying it will be up-dating its Ts and Cs.

Who?

It did look horribly genuine and the View Source tool suggested innocence, but suspicious, I investigated by Google to find Dropbox is a genuine company.

Only… it is a company I have never used.

Delete!

“Dropbox is the (Google) site for file transfers” – very conveniently it saves you the bother of keeping the advertisers up to date with your thinking.

Follow-up.

I examined the Drop-box web-site, found a text-contact tool and reported the matter. The help technician was surprised but grateful and apologetic. It might genuinely have been from them by some error, I suppose.

Although Dropbox does seem primarily intended for business users having to archive and exchange large numbers of files, it does mention home use as well.
