- A new type of ATM fraud has just arrived in London.
-
- An auction was advertised at which video cassette recorders and other
- consumer electronic goods were for sale at very low prices. A lot of
- people turned up and were asked to provide identification at the door -
- this is normal enough at auctions in Britain - and the preferred means
- of identification was a bank or credit card (you had to swipe it in a
- reader and enter your PIN at a nearby keypad).
-
- A much simpler (and successful) fraud is to steal someone's wallet or
- purse. This usually yields the victim's phone number as well as ATM
- cards. The fraudster then calls the victim claiming to be a police
- officer or bank security official and asks for the PIN number for
- "verification" or "for their report".
-
- What's the point of designing wonderful cryptographic systems when the
- customer corporations think they know it all and build implementations
- that are trivial to break even without cryptanalysis?
-
- Indeed. The UK banks do tell customers to keep PIN numbers secret, but
- they don't properly explain why this is necessary. Even so, it is
- disgraceful that their systems fail to take account of the possibility
- that the key becomes compromised. This is not an unreasonable
- assumption given human nature - witness the scams above or the stories
- about people who write down their PINs.
