Petya Ransomware Campaign 

New Zealand cyber security agencies – the National Cyber Security Centre (NCSC) and CERT NZ - are aware of international reports of a new international ransomware campaign. The ransomware has been identified as “Petya”. 

The New Zealand National Cyber Security Centre (NCSC) provides services to government agencies, critical infrastructure providers and organisations of national significance, to assist them to defend against cyber-borne threats. The NCSC has released an advisory relating to this campaign directly to our customers.

Members of the public and other organisations wanting further information can refer to guidance on the CERT NZ website:

Response to WannaCry global ransomware attack

New Zealand cyber security authorities are aware of a significant international ransomware campaign - WannaCry.

The attack uses malware to encrypt victims data and demands victims pay a ransom to have their data restored.

The National Cyber Security Centre (NCSC) is working with the newly established CERT NZ to help protect New Zealanders from this form of attack.

The NCSC is taking steps to help increase the resilience of New Zealand’s nationally significant systems. These steps include technical measures and provision of mitigation advice.

The NCSC is aware that the ransomware exploits a known vulnerability in Windows operating systems and has previously provided advice to customers on addressing this vulnerability.

We are also working with CERT NZ to provide information on how individuals, small businesses and operators of larger systems can reduce their vulnerability to ransomware attacks.

Neither the NCSC or CERT NZ have received any reports of a New Zealand incidence of this ransomware attack.

NCSC advice in response to global cyber intrusion campaign

6 April, 2017 

The National Cyber Security Centre (NCSC) is aware of a global cyber intrusion campaign targeting multi-national IT service providers.

Given the global nature of the campaign our response has been informed through consultation with our security partners.

There is no suggestion that this campaign is targeting the general public or small to medium enterprises.

The NCSC has provided advice on threat protection and response to key government and private sector organisations.

Our recommendations to organisations include:

  1. Carry out an investigation to check networks for any of the indicators included in the PwC UK and BAE systems reports.
  2. Audit administrative access into your organisation’s networks (especially via third parties) and carry out the recommendations in the NCSC Advisory NCSC CSA-006-17

We note that IP addresses in isolation are not considered to be strong indicators of a compromise. Activity related to IP addresses should be examined in the context of overall network traffic within each organisation to determine whether or not it may be malicious.

If you identify any activity that appears to be malicious, or would like to discuss this particular threat further, please call the NCSC incident line on  04 498 7654.

NCSC Cyber Threat Report 2015/16

9 March, 2017

National Cyber Security Center (NCSC) recorded 338 cyber security incidents in the 12 months 30 June 2016.

Information about these incidents is contained in a cyber threat report prepared by the NCSC to help increase understanding about the nature and extent of the cyber threats facing New Zealand's siginificant organisations.

NCSC Director Lisa Fong says the report highlights the range of threats the NCSC has identified and responded to.

She says while the report highlights that cyber threats facing New Zealand are continuing to increase it is likely that the threats recorded represent only a small proportion of the total incidents impacting on New Zealand and New Zealanders.

She says the threats the NCSC has identified targeting New Zealand organisations are consistent with those identified by cyber security providers domestically and internationally.

The report provides an overview of the work of the NCSC and an outline of some of the common types of threats impacting on New Zealand organisations.
