The Government Communications Security Bureau (GCSB) say it has "established clear links between the Russian government and a campaign of malicious cyber activity" which they say is targeting overseas political institutions, businesses, media and sporting organisations.
The GCSB announced its findings in a statement released today.
"The GCSB has worked through a robust attribution process which strongly links four international malicious cyber incidents since 2015 to the Russian government," Director-General Andrew Hampton said.
"The nature of these campaigns is complex. The GCSB's assessment found it was highly likely the Russian military General Staff Main Intelligence Directorate (GRU) was behind the campaigns and that a number of cyber proxy groups associated with these incidents are actors of the Russian state.
"Our process considered material from our partners and our own cyber threat analysis."
The United Kingdom’s National Cyber Security Centre has today also announced it assesses the GRU is behind this activity. An analysis consistent with the GCSB's.
"These malicious cyber activities serve no legitimate national security interest. They were designed to negatively impact on the ability of people around the world to go about their daily lives free from interference," Mr Hampton said.
“Such behaviour is unacceptable – it is counter to New Zealand’s vision for an open, safe and secure cyberspace.
"New Zealand organisations were not directly affected by these malicious cyber activities. We are, however, seeing a range of activity in New Zealand that contains indicators which can be linked to Russian state actors.
"These incidents reinforce the need for New Zealand to have robust national systems to address cyber threats. Initiatives such as the GCSB’s CORTEX cyber defence capabilities and the proposed expansion of the Malware-Free Networks programme help protect our nationally significant organisations," Mr Hampton said.
The Government says it's taking a fresh look at the current Cyber Security Strategy to ensure New Zealand is equipped to handle increasing cyber security threats.
