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 risk actors affiliated with China, together with Salt Storm, 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 concentrating on Australian governments, essential infrastructure, and companies utilizing evolving tradecraft over the newest reporting interval.
What’s Salt Storm?
Lately, the U.S. revealed {that a} China-connected risk actor, Salt Storm, compromised the networks of at the 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 Storm has reached Australian telco firms. Nonetheless, Grant Walsh, telco business lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and accomplice companies – would problem such detailed steering if the risk was not actual.”
“Telco networks have invested in a few of the most mature cyber defences in Australia. However the international risk 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 Storm: A part of a wider state-sponsored risk 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, 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 info and communications expertise networks for disruptive cyberattacks in opposition to U.S. essential infrastructure within the occasion of a significant disaster.
The ASD famous that Australian essential infrastructure networks may very well be weak to comparable 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 mentioned China’s selection of targets and sample of behaviour is per pre-positioning for disruptive results relatively than conventional cyber espionage operations. Nonetheless, 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 massive portions of knowledge, so are probably a goal for such a exercise.”
Frequent strategies utilized by state-sponsored attackers
In response to Walsh, China-sponsored actors like Salt Storm are “superior persistent risk actors.” Not like ransomware teams, they aren’t in search of fast monetary achieve however “need entry to the delicate core elements of essential infrastructure, like telecommunications, for espionage and even harmful functions.”
“Their assaults are usually not about locking up programs and extracting quick income,” in accordance with Walsh. “As an alternative, 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 knowledge and even disrupt or destroy belongings within the occasion of future battle with Australia.”
The ASD has warned defenders concerning the frequent strategies these state-sponsored risk actors leverage.
Provide chain compromises
The compromise of provide chains can act as a gateway to focus on networks, in accordance with the ASD. The company famous, “Cyber provide chain danger administration ought to type a significant factor of an organisation’s total cyber safety technique.”
Dwelling off the land strategies
One of many causes state-sponsored actors are so troublesome to detect, in accordance 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 “dwelling off the land” strategies contain ready to steal info from an organisation’s community.
Cloud strategies
State-sponsored risk actors adapt their strategies to use cloud programs for espionage as organisations transfer to cloud-based infrastructure. The ASD mentioned strategies for accessing an organisation’s cloud companies embody “brute-force assaults and password spraying to entry extremely privileged service accounts.”

defend in opposition to cyber threats
There are some similarities in risk actors’ strategies and the weaknesses within the programs they exploit. The ASD mentioned state-sponsored cyber actors typically use beforehand stolen knowledge, corresponding to community info and credentials from earlier cyber safety incidents, to additional their operations and re-exploit community gadgets.
Fortunately, firms can shield themselves from cyber-attacks. Earlier this yr, TechRepublic consolidated knowledgeable recommendation on how companies can defend themselves in opposition to the most typical cyber threats, together with zero-days, ransomware, and deepfakes. These strategies included retaining software program up-to-date, implementing endpoint safety options, and growing an incident response plan.
