Digital wallets as in Apple/Google Pay? I had a similar thing happen and I am wondering what did you make of this double charge, what did the attackers do in your opinion?

no it's like a continuation of your credit card for recurring payments.

It's called Automatic Billing Updater (ABU)

the idea is that if you ask for a new credit card after being stolen, your say utility providers or other like netflix subscriptions can seamlessly switch over to the new credit card number.

it worked fine for a while, but of course the problem is that afterwards the stolen credit card credentials started to be refreshed as well.

(used ai to fetch the list below).

Visa: Visa Account Updater (VAU) Mastercard: Automatic Billing Updater (ABU) American Express: Cardrefresher General: Recurring Payment Tokenization
