There was an interesting report in the Irish Sunday Mirror at the weekend about how local crims are using random number generators to attack bank account users and buy stuff online.
It's difficult to work out what's really going on, but it seems that Irish payment cards have the account number at the start of the main card number, rather than at the end as is the case with UK Maestro cards.
By randomly generating the numbers and - presumably - adding extra numbers on the end, the crims are reported to have been able to buy stuff online using forged card details.
This implies that the the crims have cracked the checksum algorithms used on the Irish bank payment card system, as the paper quotes several banking industry experts in Ireland as saying they are aware of the problem.
