SAN FRANCISCO, Feb. 15 (Xinhua) -- Private records of hundreds of thousands of customers of U.S. FedEx service, including those from China, were found stored on an unsecured Amazon S3 server, a security research center reported Thursday.

A total of 119,000 passports, driver's licenses, photo IDs and other documentation of FedEx customers with names, home addresses, phone numbers and zip codes were found to be stored on the Amazon S3 Cloud server that were accessible to the public as of Tuesday, when the server was secured.

Those customers included the United States, Mexico, Canada, Australia, Saudi Arabia, Japan, China, and several European countries, said an online report of the Kromtech Security Center (KSC).

It said the exposed data belonged to Bongo International LLC, a company specialized in helping North American retailers and brands sell online products and services to consumers in other countries.

"After a preliminary investigation, we can confirm that some archived Bongo International account information located on a server hosted by a third-party, public cloud provider is secure," FedEx said in a statement.

Bongo was purchased by FedEx in 2014 and renamed FedEx Cross-Border International 14 months later. However, the service was suspended in April 2017.

FedEx noted that the scanned data was part of a service that was discontinued after its acquisition of Bongo.

"We have found no indication that any information has been misappropriated and will continue our investigation," FedEx said.
