Happened upon a interesting article today – https://www.zdnet.com/article/banco-do-brasil-launches-cash-withdrawals-via-whatsapp/. As URL already states they are enabling users to withdraw cash from ATM’s via WhatsApp.
Basically what they say is that, the user needs to add a chatbot to their contact list and ask it for money. Then the chatbot gives them a “key” that is valid for a day. Although the service has a 80$ transaction limit, it still feels like a bad idea to me. I can already feel the new “malware wave” coming that tries to exploit this thing on the phones.
When thinking about this service, I really would love to see the analysis they made to say this is a really secure thing to do. How is this channel secured? How are they protecting people against “theft via malware”? I feel like I need to do some research in to that.
