I checked my wallet today and it said I had 2 satoshi uncofirmed. So I checked the history and there were 2 incoming transactions for 1 satoshi each that were hours old and unconfirmed. What is weirder is when I checked the address I received the bitcoin with it was not in my receive addresses. It must be part of the keypool.

This is the address.

I hopped on blockchain.info and tracked who sent me the 1 satoshi tx's and its one address sending to thousands of "random?" addresses. Always 1 satoshi.

Could this be someone attempting to map a bunch of addresses or something more nefarious?

Here is the blockchain.info link to the address that sent me the 2 tx's.

and another one that was part of the same group of transactions.

Can anyone explain this odd behavior?

Could the vanity addresses mean something? lol

I also just found this. It looks like its happening to alot of people.
