Or even Whatsapp, which people already have installed on their phone. No need to go to the store to install anything.
A scammer managed to convince a relative to share their screen during a Whatsapp video call. Luckly, said relative didn't use banking apps on the phone, the bank rejected as suspicious the transaction on the computer which would have sent money to the scammer, and the relative asked me for help before going to the ATM to unblock the account (I then contacted the bank and had them fully block the account as a precaution, and told my relative to go to the bank branch the next day to change the passwords and unblock the account).
