The weekend media reported on a virus called WannaCry that is targeting computers of public organisations and private companies around the world.
Some schools may have been affected by this virus and we are writing to let you know what you should do and what we are doing to protect schools.
WannaCry is malicious software that is taking control of computer systems by blocking access to a device, then demanding a ransom to unblock it. The virus, a type of ransomware, is largely being spread through emails when users click on links or attachments. Once a device is infected, the virus can quickly spread to all devices using your organisation’s network.
You can read more about WannaCry in New Zealand from CERT (Computer Emergency Response Team), the lead government agency monitoring the situation and providing advice on cyber security threats.
If your school has been infected, please report the incident to CERT immediately via its website: https://www.cert.govt.nz/businesses-and-individuals/report-an-issue/ and do not pay the ransom.
N4L has blocked all traffic on the Managed Network that is attempting to connect to malicious IP addresses known to be associated with this virus. They are also actively monitoring the Managed Network to spot traffic patterns that may indicate suspicious activity from connected devices.
Web safety and cyber security requires continuous vigilance, education and duty of care around how devices are used. This virus may evolve and we will continue to work closely with our technology partner, Spark, and government agencies such as Ministry of Education, CERT and Netsafe to help schools keep their online environments safe for teaching and learning.
