Researchers who work for an Israeli computer security company say
they have discovered a fundamental weakness in the system that banks
use to keep debit card PIN codes secret while they are transported
across bank networks – a flaw that they say could undermine the entire

obtained a memo compiled by the agency that indicates that organized
criminals are systematically attempting to subvert the ATM system and
unscramble encrypted PIN traffic.
The report has ignited a debate within the banking industry, with
many financial industry experts downplaying the seriousness of the flaw
and outside experts divided on its implications. But there is no
disputing the impact that such a hack would have if successful.
