While Twitter has remained largely quiet on the hour-long hijacking of its domain name, additional information suggests that the attacker had compromised at least one user at the social networking company.
On Thursday, an unknown attacker hijacked Twitter's domain name and redirected visitors to an unrelated site hosting a page claiming Twitter had been hacked by the "Iranian Cyber Army." Evidence indicates, however, that the attackers were able to change the domain-name system (DNS) entries at Twitter's provider, Dyn Inc., said Rod Rasmussen, president and CEO of Internet Identity, an infrastructure security firm which monitors DNS changes.
