The exchange went offline at 11.24am but was back up and running at 12:24pm, however some trading is halted. “NZX is currently experiencing network connectivity issues. The NZX Main Board, NZX Debt Market and Fonterra Shareholders Market are currently halted. Further information will be provided soon,” the NZX said on its website. Yesterday, trading was halted for an hour in the afternoon. In a joint statement with Spark, NZX said yesterday it “experienced a volumetric DDoS (distributed denial of service) attack from offshore, which impacted NZX system connectivity”. “As such, NZX decided to halt trading in its cash markets at approximately [3.57pm]. A DDoS attack aims to disrupt service by saturating a network with significant volumes of internet traffic.” The statement added that the attack “was able to be mitigated and connectivity has now been restored for NZX”. Professor Dave Parry, Department of Computer Science at AUT, said it was a very serious attack on critical infrastructure in New Zealand. “The fact that this has happened on a second day indicates a level of sophistication and determination which is relatively rare. “A Distributed Denial of Service attack (DDoS) works by overloading traffic to internet sites e.g. web servers, etc. This means the web servers cannot service transactions normally and this is clearly a huge issue for a trading site where timing and assurance that transactions have completed are both critical.” Parry said that it is not an issue around New Zealand computers being vulnerable to security breaches, but “it is worth checking that antivirus and security patches are up to date”. _______________________________________________ BreachExchange mailing list sponsored by Risk Based Security BreachExchange () lists riskbasedsecurity com If you wish to Edit your membership or Unsubscribe you can do so at the following link: https://lists.riskbasedsecurity.com/listinfo/breachexchange
