Ensuring the domain site was not hacked, Meer said: “Now, google.com.bd is fully operational.” An IT expert told the Dhaka Tribune that the problem could have surfaced due to “DNS cache poisoning” – a type of attack that exploits vulnerabilities in the domain name system (DNS) to divert internet traffic from legitimate servers towards fake ones.
