If you lost your ATM card on the street, how easy would it be for someone to correctly guess your PIN and proceed to clean out your savings account? Quite easy according to data scientist Nick Berry, founder of [...] a Seattle technology consultancy.
He analyzed passwords from previously released and exposed tables and security breaches, filtering the results to just those that were exactly four digits long [0-9]. There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code. [...] if users select a four-digit password for an online account or other web site, it's not a stretch to use the same number for their four-digit bank PIN codes.
What he found, he says, was a "staggering lack of imagination" when it comes to selecting passwords. Nearly 11% of the 3.4 million four-digit passwords he analyzed were 1234.
