I also suffer from the exact same issue.
Today I received an sms from my bank, telling from my card was just spent 1950 HKD internationally.
I called my bank immediately and told that i did not make the transaction.
My bank canceled my card immediately.
I will learn the details of the transaction tomorrow.
The sms is as follows.
airbnb @ hmadsjjh89 1937.05 HKD
As far as I understand, my card was used by airbnb in Hong Kong. HKD is hong kong dollars currency code.
I have never been in Hong Kong.
Obviously my card was copied or my card info was stolen.
This kind of fraud is commonly made in touristic places, like hotels or restaurants.
I had been in several places in Europe this year. Italy, France, Holland and Germany.
I strongly suspect that my card info was copied in Rome or Paris.
Because I only used my credit card for paying the hotel bill in Rome and Paris. All other payments, like restaurants and cafes I made by cash.
So were you also in Italy? Where did you use your card? Especially in touristic hotels?
I strongly suspect that my card was copied in the hotel that I stayed in Rome.
This kind of fraud is made in vast numbers, in hotels. And then the fraudelent personnel wholesale sell these card numbers to other crime organizations.
