The e-mail server of Biman Bangladesh Airlines, which went under the control of hackers, could not be recovered even after five days.
The hackers also demanded a large amount of ransom after taking control of the server following a ransomware attack.
Officials of the national flag carrier said Biman’s mail server was infected with ransomware on Friday. Ransomware is a special type of malware that can take control of a computer or server.
State Minister for Civil Aviation and Tourism Md Mahbub Ali said a probe committee was formed in this regard.
When asked if any information has been leaked by the hackers, Mahbub said such details about the matter were still unknown.
