US CERT advice on response to Meltdown and Spectre

The National Cyber Security Centre is aware of a set of security vulnerabilities known as Meltdown and Spectre that affect modern computer and mobile device processors.   Applying the latest security updates from vendors should reduce vulnerability to these issues.

More information on response to Meltdown and Spectre is available from the United States National Cybersecurity & Communications Integration Centre – part of the US Department of Homeland Security.



New Zealand concerned at North Korean cyber activity

The Director-General of the Government Communications Security Bureau (GCSB), Andrew Hampton says he is concerned at international reports which link North Korea to WannaCry. 

WannaCry was a significant global ransomware campaign, launched in May 2017, which encrypted data and demanded a ransom payment to unlock computers in over 150 countries, and significantly affected the UK’s National Health Service.

“Cyber threat analysis from a range of sources, including the United States and the United Kingdom, attributes WannaCry to North Korean cyber threat actors,” Mr Hampton said.

“While New Zealand was not significantly impacted by WannaCry, we are not immune from this type of threat. In a globally connected world our relative geographic isolation offers no protection from cyber threats.

“We support the actions of our cyber security partners in calling out this sort of reckless and malicious cyber activity.

“In the 12 months from June 2016 to June 2017 nearly one third (122) of the 396 serious incidents recorded by the GCSB’s National Cyber Security Centre involved indicators that have previously been linked to state-sponsored actors.

“Cyber threats continue to increase, in part because of New Zealand’s global connectivity but also because the cost barriers are low, and getting lower, while the potential for harm is vast.

“The GCSB has two main functions, collecting intelligence in accordance with the Government’s priorities and providing cyber security and information assurance services to organisations of national significance, from both the public and private sector.

“As part of this work, the Cortex cyber security programme has been rolled out to a group of nationally significant organisations in the public and private sectors.

 “An independent assessment of the Cortex programme showed that over a 12 month period it has saved New Zealand’s most important organisations around $40 million in harm.”

December 2017 New Zealand Information Security Manual

The New Zealand Information Security Manual (NZISM) has been updated to include new guidance on audit evidence, cable trays and clarification on emergency procedures.

The December 2017 NZISM v2.7 updates the previous edition NZISM v2.6 which was published in July 2017.

Changes include new paragraphs on Audit Evidence (Section 4.3); Cable Trays (Section 10.1); and updates to Emergency procedures (Section 5.7).  Extensive work has also been done in updating Section 23.2 Glossary of Terms, including new terms such as Accountable material and Codewords.  

A large number of supporting amendments and other minor and editorial updates have also been completed as points of clarification and to aid policy interpretation, as well as minor wording changes for the purposes of clarification.

All new materials and amendments are designed to simplify approaches while maintaining existing levels of governance and assurance. 

2016-17 Unclassified Cyber Threat Report

NCSC 2016-17 Unclassified Cyber Threat Report

The National Cyber Security Centre has produced an unclassified cyber threat report for the 2016-17 reporting year. 

The report highlights achievements, including completing the roll out of our CORTEX cyber defensive capabilities, and identifies some of the key cyber threats impacting on New Zealand’s important systems and networks. 

It notes that advanced cyber threats have the potential to cause $640m harm annually to New Zealand’s organisations of national significance and that the operation of the NCSC’s cyber defence capabilities reduced harm by $39.47m in the 2016–17 year. 

The report also notes that the NCSC recorded 396 incidents for the 2016-17 year, an increase of 58 over the previous year. The increase reflects the evolving threat landscape and the NCSC’s increased capacity to detect and respond to threats. 

Given the NCSC’s primary focus on nationally significant organisations and cyber threats with the potential to have a high impact, these numbers reflect only a small proportion of the total cyber harm occurring in New Zealand.

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.

If you experience such an attack you should contact
