From the BBC:
Bank account details belonging to thousands of Britons are being sold in West Africa for less than £20 each, the BBC's Real Story programme has found.
It discovered that fraudsters in Nigeria were able to find internet banking data stored on recycled PCs sent from the UK to Africa.
The information can be found on a PC's hard disk, which is easy to access if the drive is not wiped before sending.
Anti-fraud expert Owen Roberts said simply deleting files was not enough.
Users should instead use a programme to wipe their hard drive before they sell or give away their PC, a process which over-writes what is already contained on the drive.
Alternatively, people should remove their hard drives before they give away their computers, he said.
Is internet fraud the national sport in Nigeria or something?
