Bangladesh Bank Spokesperson and Executive Director Arif Hossain Khan said that, as part of caution amid fears of cyber attacks worldwide, the central bank's website was kept closed for error testing. Commercial banks that have temporarily shut down their websites for security reasons will also be brought back online quickly. He said that even though the websites were closed, internet and mobile banking transactions were completely normal over the past three days.

​It may be noted that recently, two serious security vulnerabilities were identified in ‘PHP’, a widely used programming language for building websites, creating a cyber risk worldwide. As a result, governments and institutions in various countries kept their websites temporarily closed as a precautionary measure from Wednesday night.
