Zappos has admitted that information of up to 24 million customers of the online retailer may have been compromised by a hacking attack.
According to the online retailer, hackers may have gotten away with the names, email addresses, addresses, phone numbers and password hashes of the said number of customers.
However, Zappos – a subsidiary of Amazon – stressed that no credit card information of the 24 million customers have been exposed.
It did say, however, that the hackers may have gotten the last four digits of the credit card numbers of the customers.
In the announcement, Zappos detailed that the customers suspected of having their accounts stolen are required to reset their passwords.
Currently, Zappos is blocking international traffic from accessing its sites. This blocks customers outside the U.S. from viewing the statement coming from Zappos CEO Tony Hsieh explaining the breach.
However, according to reports, the breach happened as hackers gained access to parts of the Zappos internal network and systems via a compromised server in Kentucky.
