WELLINGTON – New Zealand Stock Exchange (NZX) collapsed for a fourth day in a row due to cyber-attacks, it is announced on Friday, Xinhua news agency reported.
The NZX website went down on Friday morning before being restored briefly at about 10.30 am local time, but collapsed again minutes later. Its website indicates a host error.
The NZX issued a memo to the market at 8.31 am on Friday. It is said that the exchange would open as normal. The NZX also said it had been working with its network service provider Spark, and national and international cyber security partners, including the Government Communications Security Bureau, to address the cyber-attack issue.
It is understood that the NZX website was under cyber-attack. The type of attack was known as a distributed denial of service attack (DDoS), which overwhelms the online service, rendering it inoperable.
On Tuesday, the NZX website was hit by the similar cyber-attack which forced it to halt trading. The site went down again on Wednesday and Thursday for the same reason.
