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 crucial communications infrastructure.
The information comes weeks after the Australian Indicators Directorate’s Annual Cyber Risk Report 2023-2024, the place the company warned that state-sponsored cyber actors had been persistently focusing on Australian governments, crucial infrastructure, and companies utilizing evolving tradecraft over the latest reporting interval.
What’s Salt Hurricane?
Just lately, the U.S. revealed {that a} China-connected menace actor, Salt Hurricane, compromised the networks of no less than eight U.S.-based telecommunications suppliers as a part of “a broad and important cyber espionage marketing campaign.” However the marketing campaign isn’t 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 problem such detailed steering 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 have been searching for to place themselves on info and communications expertise networks for disruptive cyberattacks towards U.S. crucial infrastructure within the occasion of a significant disaster.
The ASD famous that Australian crucial infrastructure networks could possibly be susceptible 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 searching for 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 keeping 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 targets in Australia.
“State actors have a permanent curiosity in acquiring delicate info, mental property, and personally identifiable info to realize strategic and tactical benefit,” the report mentioned. “Australian organisations typically maintain giant portions of information, so are probably a goal for this sort of exercise.”
Frequent methods utilized by state-sponsored attackers
In response to Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” In contrast to ransomware teams, they don’t seem to be searching for rapid monetary acquire however “need entry to the delicate core elements of crucial infrastructure, like telecommunications, for espionage and even damaging functions.”
“Their assaults should not about locking up methods and extracting quick income,” in keeping with Walsh. “As a substitute, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect methods to get inside crucial infrastructure and keep there, doubtlessly for years. They’re ready to steal delicate knowledge and even disrupt or destroy property within the occasion of future battle with Australia.”
The ASD has warned defenders concerning the frequent methods these state-sponsored menace actors leverage.
Provide chain compromises
The compromise of provide chains can act as a gateway to focus on networks, in keeping with the ASD. The company famous, “Cyber provide chain danger administration ought to kind a major factor of an organisation’s total cyber safety technique.”
Dwelling off the land methods
One of many causes state-sponsored actors are so troublesome to detect, in keeping with the ASD, is as a result of they use “built-in community administration instruments to hold out their targets and evade detection by mixing in with regular system and community actions.” These so-called “residing off the land” methods contain ready to steal info 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 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’ methods and the weaknesses within the methods they exploit. The ASD mentioned state-sponsored cyber actors typically use beforehand stolen knowledge, 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 professional recommendation on how companies can defend themselves towards the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These options included holding software program up-to-date, implementing endpoint safety options, and growing an incident response plan.
