New Zealand’s eavesdropping agency used an Internet mass surveillance system to target government officials and an anti-corruption campaigner on a neighboring Pacific island, according to a top-secret document.
Analysts from Government Communications Security Bureau, or GCSB, programmed the Internet spy system XKEYSCORE to intercept documents authored by the closest aides and confidants of the prime minister on the tiny Solomon Islands. The agency also entered keywords into the system so that it would intercept documents containing references to the Solomons’ leading anti-corruption activist, who is known for publishing government leaks on his website.
XKEYSCORE is run by the National Security Agency, and is used to analyze billions of emails, Internet browsing sessions and online chats that are collected from some 150 different locations worldwide. GCSB has gained access to XKEYSCORE because New Zealand is a member of the Five Eyes surveillance alliance alongside the United States, the United Kingdom, Canada and Australia.
