[Apologies if this is off topic for the thread. Please point me in the right direction.]

I received this SMS alert today from the 63660 number.

This is suspicious as I don't have a RHB card, nor was I at klia2. Besides, the fact that it says klia2 and not some specific shop triggered even more alarms.

I didn't call the number, but have checked to make sure there has been no suspicious activities with my actual credit cards from other banks.

Is this a some sort of scam?

Thanks.
