The other day I got an e-mail titled "authorize API access attempt". I received another one today titled the same thing, and these are the contents of the message:
An attempt has been made access your blockchain.info wallet through the wallet api.

I haven't used my blockchain wallet in approx two weeks; the first time I got the message I had a hint of doubt that I might have tried to access it while I was drunk or something and forgot. However, this time I know for sure it wasn't me. I haven't really ticked off anyone on DNMs (that i know of), the closest thing would be giving a vendor an OK review not too long ago.
Can anyone give me some insight as to who the culprit might be, or what I can do to make my coins more secure? I'm not too worried about it right now, as I only have about a couple of bucks worth in it at the moment. But if I decide to buy something again, I don't want to be constantly worrying that someone will steal my coins.
