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 know-how professionals to watch out for risk actors affiliated with China, together with Salt Storm, infiltrating their vital communications infrastructure.
The information comes weeks after the Australian Alerts 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, vital infrastructure, and companies utilizing evolving tradecraft over the latest reporting interval.
What’s Salt Storm?
Just lately, the U.S. revealed {that a} China-connected risk actor, Salt Storm, compromised the networks of at the very least eight U.S.-based telecommunications suppliers as a part of “a broad and vital cyber espionage marketing campaign.” However the marketing campaign shouldn’t be restricted to U.S. shores.
Australian companies didn’t affirm whether or not Salt Storm 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 accomplice companies – would challenge 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, notably these related to China.”

Salt Storm: A part of a wider state-sponsored risk drawback
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, 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 in search of to place themselves on info and communications know-how networks for disruptive cyberattacks towards U.S. vital infrastructure within the occasion of a significant disaster.
The ASD famous that Australian vital infrastructure networks might 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 selection of targets and sample of behaviour is according to pre-positioning for disruptive results moderately 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 an everlasting curiosity in acquiring delicate info, mental property, and personally identifiable info to achieve strategic and tactical benefit,” the report mentioned. “Australian organisations typically maintain massive portions of information, so are possible a goal for this sort of exercise.”
Frequent methods utilized by state-sponsored attackers
Based on Walsh, China-sponsored actors like Salt Storm are “superior persistent risk actors.” In contrast to ransomware teams, they don’t seem to be in search of quick monetary achieve however “need entry to the delicate core parts of vital infrastructure, like telecommunications, for espionage and even damaging functions.”
“Their assaults aren’t about locking up techniques and extracting quick earnings,” in keeping with Walsh. “As a substitute, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect methods to get inside vital infrastructure and keep there, doubtlessly 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 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 keeping with the ASD. The company famous, “Cyber provide chain threat administration ought to type a significant factor of an organisation’s general cyber safety technique.”
Residing off the land methods
One of many causes state-sponsored actors are so tough 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 risk actors adapt their methods to use cloud techniques 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.”

Methods to defend towards cyber threats
There are some similarities in risk actors’ methods and the weaknesses within the techniques they exploit. The ASD mentioned 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 professional recommendation on how companies can defend themselves towards the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These options included maintaining software program up-to-date, implementing endpoint safety options, and growing an incident response plan.
