New Zealand's Stock Exchange Market (NZX) faced a distributed denial of service (DDoS) attack for four days, forcing the government to activate the country's National Security System. The cyber-attacks disrupted cash and debt markets and the Fonterra shareholders market, including its derivatives. The Fonterra Co-operative Group is the world's largest milk exporter.
Though the New Zealand government has not been able to pinpoint the source of the attack, government agencies have stated that the cyber-attack originated from 'offshore sources'.
