CyberBunker was an Internet service provider located in the Netherlands and Germany that, according to its website, "hosted services to any website except child pornography and anything related to terrorism". The company first operated in a former NATO bunker in Zeeland, from which it got its name,[1] and later in another former NATO bunker in Traben-Trarbach, Germany. Sven Olaf Kamphuis referred to CyberBunker as the Republic of CyberBunker and referred to himself as the Minister of Telecommunications and Foreign Affairs.[2][3]
CyberBunker served as a web host for The Pirate Bay and as one of the many WikiLeaks mirrors.[4] CyberBunker has also been accused of being a host for spammers, botnet command-and-control servers, malware, and online scams.[5] The company has also been involved in Border Gateway Protocol hijacks of IP addresses used by Spamhaus and the United States Department of Defense.[6] The Spamhaus hijack was part of an exceptionally large distributed denial of service attack launched against them in March 2013. Because of the size of this attack it received considerable mainstream media attention.
As of 2013, CyberBunker listed its address as the bunker, but the location of CyberBunker's servers was unclear.[7]
In September 2019, the German police stormed and shut down the company's operations in its bunker in Traben-Trarbach. Seven suspects were arrested.[8]
