The Australian Alerts 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 beware of threat actors affiliated with China, together with Salt Hurricane, infiltrating their crucial communications infrastructure.
The information comes weeks after the Australian Alerts Directorate’s Annual Cyber Threat 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 newest reporting interval.
What’s Salt Hurricane?
Just lately, the U.S. revealed that a China-connected threat actor, Salt Hurricane, compromised the networks of no less than eight U.S.-based telecommunications suppliers as a part of “a broad and vital 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. Nonetheless, Grant Walsh, telco business lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and companion businesses – would difficulty such detailed steerage if the risk was not actual.”
“Telco networks have invested in among the most mature cyber defences in Australia. However the world 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 Hurricane: A part of a wider state-sponsored risk drawback
Over the previous 12 months, 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 info and communications expertise networks for disruptive cyberattacks in opposition to U.S. crucial infrastructure within the occasion of a serious disaster.
The ASD famous that Australian crucial 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 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 according to pre-positioning for disruptive results slightly 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 usually maintain massive portions of information, so are seemingly a goal for any such exercise.”
Frequent methods utilized by state-sponsored attackers
In keeping with Walsh, China-sponsored actors like Salt Hurricane are “superior persistent risk actors.” Not like ransomware teams, they aren’t in search of quick monetary achieve however “need entry to the delicate core parts of crucial infrastructure, like telecommunications, for espionage and even damaging functions.”
“Their assaults usually are not about locking up methods and extracting quick income,” in response to Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect methods to get inside crucial 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 methods these state-sponsored risk actors leverage.
Provide chain compromises
The compromise of provide chains can act as a gateway to focus on networks, in response to the ASD. The company famous, “Cyber provide chain threat administration ought to type a significant factor of an organisation’s general cyber safety technique.”
Dwelling off the land methods
One of many causes state-sponsored actors are so tough to detect, in response to 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 risk 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.”

Learn how to defend in opposition to cyber threats
There are some similarities in risk actors’ methods and the weaknesses within the methods they exploit. The ASD mentioned state-sponsored cyber actors usually use beforehand stolen knowledge, resembling community info and credentials from earlier cyber safety incidents, to additional their operations and re-exploit community units.
Fortunately, firms can shield themselves from cyber-attacks. Earlier this 12 months, TechRepublic consolidated professional recommendation on how companies can defend themselves in opposition to the most typical cyber threats, together with zero-days, ransomware, and deepfakes. These options included holding software program up-to-date, implementing endpoint safety options, and creating an incident response plan.
