The company operating the site, register.com, has been sued
for gross negligence for failing to stop the hacker attack that
redirected Baidu's domain to a different IP address. Baidu's
main site was down for about four hours. In addition, Baidu was
unable to access its account to re-register the DNS entry. The
specific Baidu claims are trademark infringement, breach of
contract and negligence, under the Lanham act.
The redirected website had a flag of Iran, a broken star of
David (a Jewish sacred symbol), and "Iranian Cyber Army"
written on it. Chinese hackers retaliated the next day attacking
Iranian websites, but it seems likely the Iranian connection
is a red herring.
The case is Baidu Inc v Register.Com Inc, U.S. District Court
for the Southern District of New York, No. 10-444.
