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 expertise professionals to watch out for menace actors affiliated with China, together with Salt Hurricane, infiltrating their essential 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, essential infrastructure, and companies utilizing evolving tradecraft over the latest reporting interval.
What’s Salt Hurricane?
Lately, the U.S. revealed {that a} China-connected menace actor, Salt Hurricane, compromised the networks of a minimum of eight U.S.-based telecommunications suppliers as a part of “a broad and important cyber espionage marketing campaign.” However the marketing campaign will not be restricted to U.S. shores.
Australian businesses didn’t verify whether or not Salt Hurricane has reached Australian telco firms. Nevertheless, Grant Walsh, telco trade lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and associate businesses – would concern 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, notably 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 spotlight the evolving operations of state-sponsored cyber actors, notably 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 had been in search of to place themselves on info and communications expertise networks for disruptive cyberattacks towards U.S. essential infrastructure within the occasion of a significant disaster.
The ASD famous that Australian essential infrastructure networks could possibly be weak to related state-sponsored malicious cyber exercise as seen within the U.S.
“These actors conduct cyber operations in pursuit of state objectives, 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 stated China’s selection of targets and sample of behaviour is in keeping with pre-positioning for disruptive results slightly than conventional cyber espionage operations. Nevertheless, it stated that state-sponsored cyber actors even have information-gathering and espionage aims in Australia.
“State actors have a permanent curiosity in acquiring delicate info, mental property, and personally identifiable info to achieve strategic and tactical benefit,” the report stated. “Australian organisations typically maintain massive portions of information, so are probably a goal for this kind of exercise.”
Widespread strategies utilized by state-sponsored attackers
Based on Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” In contrast to ransomware teams, they aren’t in search of quick monetary acquire however “need entry to the delicate core parts of essential infrastructure, like telecommunications, for espionage and even harmful functions.”
“Their assaults will not be about locking up methods and extracting quick earnings,” based on Walsh. “As a substitute, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect strategies to get inside essential infrastructure and keep there, probably for years. They’re ready to steal delicate information and even disrupt or destroy property within the occasion of future battle with Australia.”
The ASD has warned defenders in regards to the frequent strategies 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 danger administration ought to type a major factor of an organisation’s total cyber safety technique.”
Residing off the land strategies
One of many causes state-sponsored actors are so tough to detect, based on the ASD, is as a result of they use “built-in community administration instruments to hold out their aims and evade detection by mixing in with regular system and community actions.” These so-called “residing off the land” strategies contain ready to steal info from an organisation’s community.
Cloud strategies
State-sponsored menace actors adapt their strategies to take advantage of cloud methods for espionage as organisations transfer to cloud-based infrastructure. The ASD stated strategies for accessing an organisation’s cloud providers embrace “brute-force assaults and password spraying to entry extremely privileged service accounts.”

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