In case you missed it, on Wednesday it was reported that millions of documents were found leaking after an exposed Elasticsearch server was found without a password. The documents contained highly sensitive financial data on tens of thousands of individuals who took out loans or mortgages over the past decade with U.S. financial institutions. The documents were converted using a technology called OCR from their original paper documents to a computer readable format and stored in the database, but they weren’t easy to read. That said, it was possible to discern names, addresses, birth dates, Social Security numbers, and other private financial data by anyone who knew where to find the server.

Independent security researcher Bob Diachenko and TechCrunch traced the source of the leaking database to a Texas-based data and analytics company, Ascension. When reached, the company said that one of its vendors, OpticsML, a New York-based document management startup, had mishandled the data and was to blame for the data leak.

It turns out that data was exposed again — but this time, it was the original documents.

Diachenko found the second trove of data in a separate exposed Amazon S3 storage server, which too was not protected with a password. Anyone who went to an easy-to-guess web address in their web browser could have accessed the storage server to see — and download — the files stored inside.
