Qatar National Bank

In July 2015, the Qatar National Bank suffered a data breach which exposed 15k documents totalling 1.4GB and detailing more than 100k accounts with passwords and PINs. The incident was made public some 9 months later in April 2016 when the documents appeared publicly on a file sharing site. Analysis of the breached data suggests the attack began by exploiting a SQL injection flaw in the bank's website.
