ATM compromises in the US jumped 546 per cent from 2014 to 2015.
One big factor in the six-fold increase is a growth in problems at non-bank ATMs, such as convenience stores, according to a study by security analytics outfit FICO.
The average duration of a compromise fell from 36 days in 2014 to 14 days in 2015.
Cardholders should employ common sense when using ATMs, and check their transactions frequently, it advises. ®
