Specifically I got a text saying the following:
Dear [My Name]
You just sent 0.02BTC (0/12 confirmations) Please visit [ledger-chain.info](https://ledger-chain.info) within 30 minutes if you need to cancel.
My Ledger account records no such transaction. WTF is this? Seems like a scam but how could they get my name and know I have a Ledger?
