Hackers have struck Zappos, the online shoe retailer, putting at risk the sensitive information from its database of 24 million customers.
Credit card information had not been stolen, Zappos chief executive Tony Hsieh said in a statement, but names, email addresses and other personal information may have been exposed.
In an email to staff sent on Sunday and posted on the company website, Hsieh wrote: “We were recently the victim of a cyber-attack by a criminal who gained access to parts of our internal network and systems through one of our servers in Kentucky. We are co-operating with law enforcement to undergo an exhaustive investigation.”
Zappos has contacted customers asking them to choose new passwords for zappos.com and other sites where they may have used the same or a similar password.
