Trading was halted on the New Zealand Stock Exchange Thursday for a third day in a row following a cyberattack earlier in the week.“NZX is currently experiencing network connectivity issues. The NZX Main Board, the NZX Debt Market and the Fonterra Shareholders Market are currently discontinued. More information will be released soon, ”the New Zealand stock exchange operator Exchange said on its website.

Trading stopped around 11:10 am local time.

NZX said on Tuesday it suffered a DDoS (Distributed Denial of Service) attack from overseas via its network service provider, disrupting the last hour of trading in its spot markets. Its websites and market reporting platform were also affected.

A day later he was reportedly faced with a similar attack, which interrupted trading at 11:24 a.m. local time until 3:00 p.m.

DDoS attacks are among the simplest forms of cyberattacks to perform. It is about delivering a large flow of information and internet traffic, usually using a network of hacked computers, to overwhelm a target’s systems.

NZX did not immediately respond to CNBC’s request for comment via email.
