I went to an actionfraud talk the other week. It was eye opening and given by an ex police officer. The minute you give your bank details to anyone, they will have open access to your account
Most crimes now are frauds and many suck you in on a social level ie befriending, interest groups etc
A bit off topic
I will not ever use my debit account to pay for anything again. A cc transaction is between the bank and the seller and anything after that the cc company is liable. A debit card payment allows open access to your money
Surely they meant more than just your account number and sort code. Giving "your bank details" includes the password and security details that go with it " Every check you write has your bank account number and sort code on it - you can't avoid giving that out if you pay by check, not by physical cash.
To get into your bank account online, you have to answer some questions about your security details and password, and if you get the answers wrong three times your account is frozen until you have personally phoned the bank and satisfied them who you are. A scammer would need to do this too.
You should NEVER give all these details to a random anonymous caller, but your bare account number and sort code have to be known by anyone who gives YOU money - your pension for a start, if it is paid directly into your bank account. They can't get money OUT with just those two facts.
