Data of millions of eBay and Amazon shoppers exposed

Researchers have discovered another big database containing millions of European customer records left unsecured on Amazon Web Services (AWS) for anyone to find using a search engine.

A total of eight million records were involved, collected via marketplace and payment system APIs belonging to companies including Amazon, eBay, Shopify, PayPal, and Stripe.

Discovered by Comparitech’s noted breach hunter Bob Diachenko, the AWS instance containing the MongoDB database became visible on 3 February, where it remained indexable by search engines for five days.

Data in the records included names, shipping addresses, email addresses, phone numbers, items purchased, payments, order IDs, links to Stripe and Shopify invoices, and partially redacted credit cards.

Also included were thousands of Amazon Marketplace Web Services (MWS) queries, an MWS authentication token, and an AWS access key ID.

Because a single customer might generate multiple records, Comparitech wasn’t able to estimate how many customers might be affected.

What we do know is everyone affected will be from the EU, with roughly half being customers in the UK.
