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 menace actors affiliated with China, together with Salt Hurricane, infiltrating their important communications infrastructure.
The information comes weeks after the Australian Alerts Directorate’s Annual Cyber Risk Report 2023-2024, the place the company warned that state-sponsored cyber actors had been persistently concentrating on Australian governments, important 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 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 just isn’t restricted to U.S. shores.
Australian companies didn’t affirm whether or not Salt Hurricane has reached Australian telco firms. Nevertheless, Grant Walsh, telco business lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and associate companies – would situation such detailed steerage if the menace was not actual.”
“Telco networks have invested in among 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, significantly these related to China.”

Salt Hurricane: A part of a wider state-sponsored menace downside
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 searching for to place themselves on data and communications know-how networks for disruptive cyberattacks in opposition to U.S. important infrastructure within the occasion of a serious disaster.
The ASD famous that Australian important infrastructure networks could possibly be susceptible 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 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 stated China’s selection of targets and sample of behaviour is according to pre-positioning for disruptive results somewhat than conventional cyber espionage operations. Nevertheless, it stated that state-sponsored cyber actors even have information-gathering and espionage targets in Australia.
“State actors have an everlasting curiosity in acquiring delicate data, mental property, and personally identifiable data to achieve strategic and tactical benefit,” the report stated. “Australian organisations usually maintain giant portions of knowledge, so are seemingly a goal for one of these exercise.”
Widespread strategies utilized by state-sponsored attackers
In keeping with Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” Not like ransomware teams, they aren’t searching for fast monetary achieve however “need entry to the delicate core parts of important infrastructure, like telecommunications, for espionage and even harmful functions.”
“Their assaults should not about locking up techniques and extracting quick earnings,” based on Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect strategies to get inside important infrastructure and keep there, probably 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 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 threat administration ought to type a significant factor of an organisation’s general cyber safety technique.”
Dwelling 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 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 data from an organisation’s community.
Cloud strategies
State-sponsored menace actors adapt their strategies to take advantage of cloud techniques for espionage as organisations transfer to cloud-based infrastructure. The ASD stated strategies for accessing an organisation’s cloud providers embody “brute-force assaults and password spraying to entry extremely privileged service accounts.”

The best way to defend in opposition to cyber threats
There are some similarities in menace actors’ strategies and the weaknesses within the techniques they exploit. The ASD stated state-sponsored cyber actors usually use beforehand stolen knowledge, comparable to community data 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 12 months, TechRepublic consolidated professional recommendation on how companies can defend themselves in opposition to the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These solutions included holding software program up-to-date, implementing endpoint safety options, and creating an incident response plan.
