Can't log in with stolen bank accounts

I just accepted a ton of "our esteemed colleague wishes to make a donation" missions where I have to steal a bank account and make a money transfer to another account.

How can I perform these missions?

There is a website dedicated to walkthrough each kind of mission, including the minimum requirement for them.
Here is the link for that specific mission Our Esteemed colleague wishes to make a donation
