A massive collection of documents from Qatar National Bank, based in Doha, was leaked and posted online to the whistleblower site Cryptome on April 26. The leaked data, which totals 1.4 GBs, apparently includes internal corporate files and sensitive financial data for QNB's customers.
Cryptome reports that the leak comprises 15,460 files, containing details, including passwords, PINs and payment card data, for hundreds of thousands of the bank customers' accounts. Multiple experts have also examined the data, and likewise report that it appears to be legitimate. But Cryptome offered no insights into how the data was obtained, for example, if it was via an external hack attack, or an inside job.
