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 know-how professionals to watch out for risk 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 Menace Report 2023-2024, the place the company warned that state-sponsored cyber actors had been persistently concentrating on Australian governments, crucial infrastructure, and companies utilizing evolving tradecraft over the newest reporting interval.
What’s Salt Hurricane?
Lately, the U.S. revealed {that a} China-connected risk 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 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 trade lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and accomplice companies – would situation such detailed steerage if the risk was not actual.”
“Telco networks have invested in a number 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, notably 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 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 data and communications know-how networks for disruptive cyberattacks in opposition to U.S. crucial infrastructure within the occasion of a significant disaster.
The ASD famous that Australian crucial infrastructure networks could possibly 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 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 relatively 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 data, mental property, and personally identifiable data to realize strategic and tactical benefit,” the report mentioned. “Australian organisations usually maintain massive portions of information, so are probably a goal for this sort of exercise.”
Frequent methods utilized by state-sponsored attackers
Based on Walsh, China-sponsored actors like Salt Hurricane are “superior persistent risk actors.” In contrast to ransomware teams, they aren’t searching for instant monetary achieve however “need entry to the delicate core parts of crucial infrastructure, like telecommunications, for espionage and even damaging functions.”
“Their assaults should not about locking up methods and extracting quick income,” in response to 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, probably 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 in regards to 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 kind a significant factor of an organisation’s total 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 “dwelling off the land” methods contain ready to steal data from an organisation’s community.
Cloud methods
State-sponsored risk actors adapt their methods to take advantage of cloud methods for espionage as organisations transfer to cloud-based infrastructure. The ASD mentioned methods for accessing an organisation’s cloud companies embrace “brute-force assaults and password spraying to entry extremely privileged service accounts.”

How you can 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 information, corresponding to community data 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 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 conserving software program up-to-date, implementing endpoint safety options, and creating an incident response plan.
