The Australian Indicators Directorate and the Australian Cyber Safety Centre have joined cybersecurity establishments from the U.S., Canada, and New Zealand in warning native know-how professionals to watch out for menace actors affiliated with China, together with Salt Hurricane, infiltrating their vital communications infrastructure.
The information comes weeks after the Australian Indicators Directorate’s Annual Cyber Menace Report 2023-2024, the place the company warned that state-sponsored cyber actors had been persistently focusing on Australian governments, vital infrastructure, and companies utilizing evolving tradecraft over the newest reporting interval.
What’s Salt Hurricane?
Just lately, the U.S. revealed {that a} China-connected menace actor, Salt Hurricane, compromised the networks of at the very least eight U.S.-based telecommunications suppliers as a part of “a broad and important cyber espionage marketing campaign.” However the marketing campaign shouldn’t be restricted to U.S. shores.
Australian companies didn’t verify whether or not Salt Hurricane has reached Australian telco corporations. Nevertheless, Grant Walsh, telco business lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and accomplice companies – would difficulty such detailed steerage if the menace was not actual.”
“Telco networks have invested in a few of the most mature cyber defences in Australia. However the world menace panorama is deteriorating,” he wrote. “Telecommunications networks are a key goal for persistent and highly-capable state-based cyber espionage teams, significantly these related to China.”

Salt Hurricane: A part of a wider state-sponsored menace downside
Over the previous yr, the ASD has issued a number of joint advisories with worldwide companions to focus on the evolving operations of state-sponsored cyber actors, significantly from China-sponsored actors.
In February 2024, the ASD joined the U.S. and different worldwide companions in releasing an advisory. It assessed that China-sponsored cyber actors have been in search of to place themselves on data and communications know-how networks for disruptive cyberattacks in opposition to U.S. vital infrastructure within the occasion of a serious disaster.
The ASD famous that Australian vital infrastructure networks may very well be weak to related state-sponsored malicious cyber exercise as seen within the U.S.
“These actors conduct cyber operations in pursuit of state targets, together with for espionage, in exerting malign affect, interference and coercion, and in in search of to pre-position on networks for disruptive cyber assaults,” the ASD wrote within the report.

Within the ASD’s annual cyber report, the company mentioned China’s alternative of targets and sample of behaviour is in step with pre-positioning for disruptive results quite than conventional cyber espionage operations. Nevertheless, it mentioned that state-sponsored cyber actors even have information-gathering and espionage goals in Australia.
“State actors have an everlasting curiosity in acquiring delicate data, mental property, and personally identifiable data to realize strategic and tactical benefit,” the report mentioned. “Australian organisations typically maintain giant portions of information, so are possible a goal for such a exercise.”
Frequent methods utilized by state-sponsored attackers
In accordance with Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” Not like ransomware teams, they don’t seem to be in search of fast monetary acquire however “need entry to the delicate core parts of vital infrastructure, like telecommunications, for espionage and even harmful functions.”
“Their assaults are usually not about locking up methods and extracting quick income,” based on Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect methods to get inside vital infrastructure and keep there, probably for years. They’re ready to steal delicate knowledge and even disrupt or destroy belongings within the occasion of future battle with Australia.”
The ASD has warned defenders concerning the widespread methods these state-sponsored menace actors leverage.
Provide chain compromises
The compromise of provide chains can act as a gateway to focus on networks, based on the ASD. The company famous, “Cyber provide chain threat administration ought to type a major factor of an organisation’s general cyber safety technique.”
Dwelling off the land methods
One of many causes state-sponsored actors are so troublesome to detect, based on the ASD, is as a result of they use “built-in community administration instruments to hold out their goals and evade detection by mixing in with regular system and community actions.” These so-called “dwelling off the land” methods contain ready to steal data from an organisation’s community.
Cloud methods
State-sponsored menace actors adapt their methods to use cloud methods for espionage as organisations transfer to cloud-based infrastructure. The ASD mentioned methods for accessing an organisation’s cloud providers embody “brute-force assaults and password spraying to entry extremely privileged service accounts.”

defend in opposition to cyber threats
There are some similarities in menace actors’ methods and the weaknesses within the methods they exploit. The ASD mentioned state-sponsored cyber actors typically use beforehand stolen knowledge, corresponding to community data and credentials from earlier cyber safety incidents, to additional their operations and re-exploit community units.
Fortunately, corporations can defend themselves from cyber-attacks. Earlier this yr, TechRepublic consolidated skilled recommendation on how companies can defend themselves in opposition to the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These options included retaining software program up-to-date, implementing endpoint safety options, and creating an incident response plan.
