Qatar National Bank is a multinational commercial bank. It was established back in 1964 and is now providing its services to 31 countries. Its net income has reached $3,32 billion in 2020. It is the largest lender in the region.
In 2016, the bank suffered from a massive data leak. Around 1,4 GB of information was posted online on the whistleblower website Cryptome. There are almost 15,500 documents with bank corporate files and customer information in clear text. There are passwords, credit card numbers, expiration dates, PINs, credit holder names, account details, credit limits, etc. Numerous sources verified that the data was legitimate. One of the users tried to use leaked information to log into the existing account for research purposes and almost succeeded. The bank luckily has two-factor authentication and did not let the user in. The breach also affected some of the government representatives and media outlets.
Qatar National Bank reacted rather questionably. They stated that they are not going to give a comment about social media speculation. However, they added that there was no financial damage and that they will secure their systems and contact those who were affected by the breach.
