It came as high-profile cyber attacks had increasingly made headlines around the world, including the Irish attack last Friday and another that shut down an important United States’ fuel pipeline this week.
The Ministry of Health said it had encouraged DHBs and their staff to have plans ready to deal with cyber incidents and be vigilant using the internet careful.

Waikato DHB’s Snee said the cyber breach occurred at 2.40am
One of the leads investigators were following was that it entered the health provider’s network through an email attachment.
“That is one working assumption, but we’re not…
