ATOM dust and UK compliance

Received random dust (0.000001 ATOM) from an unknown source and Coinbase is asking me to provide senders information as required by UK regulation.

Obviously I don't know who sent me this dust as its most definitely a scammer.

I'm not going to interact with it but want to know what to do regarding providing Coinbase the senders details.

I would rather not have my account put on hold over something like this.

Also the email from Coinbase is legit and I've got the same message in the app.
