CyberBunker

[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.

[8] In 1995, Herman-Johan Xennt bought a 20,000-square-foot (1,900 m2) bunker just outside the small town of Kloetinge in the south of the Netherlands, which had been formerly used by NATO,[9][10] and was built in 1955.

[14][9][10] Three of the four men charged with the operation of the lab were convicted to three-year prison sentences; the fourth was acquitted due to a lack of evidence.

[15] Following the fire the local town denied the company a business license, resulting in the CyberBunker servers being moved to above-ground locations, including Amsterdam.

[18] In October 2009 BitTorrent tracker The Pirate Bay, which had been subjected to legal action by various anti-piracy groups including Dutch copyright organisation BREIN, moved away from Sweden to CyberBunker.

In 2010 the Hamburg district court ruled that CyberBunker, operating in Germany as CB3Rob Ltd & Co KG, was no longer allowed to host The Pirate Bay, being subject to a €250,000 fine or up to two years' imprisonment for each infringement.

[23] Cloudflare, an Internet security firm located in San Francisco, California, assisting Spamhaus in combating the DoS attack was also targeted.

On 28 March 2013, CyberBunker's website went offline for a short period of time, possibly becoming a victim of a DDoS attack themselves.

[24] On 25 April 2013, Sven Olaf Kamphuis, a vocal spokesman for CyberBunker, was arrested at the request of Dutch authorities near Barcelona by Spanish Police after collaboration through Eurojust.

[9] During this time, the company's clients are claimed to have included the dark web marketplaces Wall Street Market, Cannabis Road and Flugsvamp, as well as Fraudsters, a forum for exchanging illegal drugs, counterfeit money and fake identification.

[9][32] The Irish criminal George Mitchell, who lived for a while in Traben-Trarbach,[33] approached Xennt about running an encrypted phone business.

[35] In 2021, Xennt and six other defendants were convicted of having formed a criminal organization, but were acquitted of having aided and abetted the crimes committed on their servers.
