The Anonymous group have hacked the website owned by the Motion Picture Association of America (MPAA) in protest against the anti-piracy campaign undertaken by the industry trade bodies.
The website, copyprotected.com, which is designed to report copyright violations in DVDs and Blu-Ray discs, was hacked to display the logo of the notorious torrent website, The Pirate Bay.
According to Sunbelt, the hackers have used the DNS cache poisoning attack in order to deface the website.
The company said: “Although the text of the defacement mentions a distributed denial of service attack, this is more than simply bringing down an MPAA web server.”
“Someone managed to hijack the DNS registration for copyprotected.com such that it points to an IP with their own web server displaying their own page,” it added.
Further investigation revealed that the IP address used in the attack is used by an organisation called WareNet, which according to Sunbelt, was unaware that one of its web server was hacked.
