In reality, the company's domain name had been hijacked by the vandals and visitors redirected to an unrelated site hosting the page. Passive domain-name service (DNS) records showed the DNS poisoning, as Twitter's record pointed first to two domains registered in Moldova and then to a domain registered to an undisclosed person in Pompano Beach, Florida, according to information posted by the SANS Internet Storm Center.
Twitter acknowledged the issue late last night, following earlier media reports.
Defacement was claimed to be done by the "Iranian Cyber Army," but another message -- translated from Farsi by Google's automated translation engine -- reportedly claimed the attack was motivated by the U.S. and Twitter's interference in "my country," suggesting the attacker was an individual.
