I had a credit card scammer posing as "Etsy Support" direct message me. This has been reported to Etsy. The link in message goes to what looks like a legit page with one of your shop listings and shop name - there is also a form on the left for verifying your shop with a credit card.
When entered, they will ask for you to confirm you own the card by entering the current available balance. Followed by a pop up asking for you to enter a one-time-authorisation code to complete a payment.
From what I was able to see, they run the payments through Stripe (also reported in detail to their security team). Any cards they can't run quick enough, all details are sent to a Telegram account (also reported) for use later.
