The effects of a cyber-attack in the US have reached up to 11 New Zealand schools, according to the Ministry of Education.
The attack targetted Florida-based software supplier Kaseya and its effects rippled around the world, affecting hundreds of businesses and crippling computer networks.
St Peter’s College in Cambridge posted on Facebook its network had been exposed to the global attack and all school systems would be inactive for at least the next 48 hours.
The system was stable and the school was working to recover data.
Yesterday the St Peter’s network was exposed to a worldwide cyber attack. The system is now stable and we are working to…
The Ministry of Education said any school that believes it might have theKaseya VSA software installed should first contact their IT provider.
“Our analysis has shown that 11 schools out of 2400 may have been affected by the ransomware attack,” said a spokesperson.
“We are working with those schools to provide them with support and will continue to identify if other schools have been impacted.”
In Sweden, about 500 Coop supermarket stores closed because of the ongoing attack after the shop’s cash registers stopped working, the BBC reported.
Partner and national leader of cyber at Deloitte Anu Nayar organisations in New Zealand used Kaseya, including some of his clients.
He had told them to stop using it until more was known around which Kaseya customers had been affected by the attack.
“It’s not as widespread in New Zealand but there are companies that use it.”
There was suspicion that Russian-linked REvil ransomware gang, one of the most prolific and profitable cyber-criminal groups in the world, was responsible for the attack.
Generally speaking, these types of ransomware attacks were funded and distributed between well organised crime groups, Nayar said.
“They are definitely quite prolific in terms of their attempts through these types of methods to compromise as many organisations as possible.”
It’s not known how many companies had been affected by the attack or asked to front up with thousands of dollars to pay a ransom to get their systems going again.
Some experts had predicted that the attack targetting Kaseya customers could be one of the broadest ransomware attacks on record, AP reported.
Kaseya said its VSA product had been targetted by the attack and it believed it had been localised to a small number of on-premises customers only, meaning clients that run their own data centres.
A sophisticated cyber attack brought the Waikato DHB’s system to its knees this year, affecting a number of operations and being described as the biggest in New Zealand’s history.
The DHB had to employ hundreds of additional IT experts as it attempted to rebuild all its systems.
