The Australian Indicators Directorate and the Australian Cyber Safety Middle have joined cyber safety companies from the US, Canada and New Zealand in warning native expertise professionals to watch out for China-affiliated menace actorstogether with Salt Hurricane, which penetrates their vital communications infrastructure.
The information comes weeks after the Directorate of Australian Indicators Annual Cyber Risk Report 2023-2024the place the company warned that state-sponsored cyber actors had persistently focused Australian governments, vital infrastructure and companies over the latest reporting interval.
What’s salt cellphone?
Not too long ago, the US revealed {that a} China-linked menace actorSalt Hurricane, compromised the networks of not less than eight US-based telecommunications suppliers as a part of “a broad and vital cyber espionage marketing campaign.” However the marketing campaign just isn’t restricted to American shores.
Australian companies haven’t confirmed whether or not Salt Hurricane has reached Australian telecommunications firms. Grant Walsh, head of telecoms at native cyber safety agency CyberCX, wrote that the ACSC — and accomplice companies — had been “unlikely to challenge such detailed steering if the menace weren’t actual.”
“Telco networks have invested in a number of the most mature cyber defenses in Australia. However the world menace panorama is deteriorating,” he wrote. “Telecommunications networks are a key goal for persistent and extremely succesful state-based cyber espionage teams, significantly these related to China.”

Saltyphone: Half of a bigger state-sponsored menace downside
The ASD has issued a number of joint advisories with worldwide companions over the previous 12 months to focus on the evolving operations of state-sponsored cyber actors, significantly China-sponsored actors.
In February 2024, the ASD joined the US and different worldwide companions challenge an advisory. It assessed that China-sponsored cyber actors are attempting to place themselves on data and communications expertise networks for disruptive cyber assaults towards US vital infrastructure within the occasion of a significant disaster.
The ASD famous that Australian vital infrastructure networks might be susceptible to related state-sponsored malicious cyber actions as seen within the US
“These actors conduct cyber operations in pursuit of state targets, together with for espionage, within the train of malicious affect, interference and coercion, and within the try to pre-position 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 conduct are per pre-positioning for disruptive results slightly than conventional cyber espionage operations. Nonetheless, it mentioned state-sponsored cyber actors even have intelligence-gathering and espionage objectives 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 mentioned. “Australian organizations typically maintain massive quantities of information, so are prone to be a goal for one of these exercise.”
Widespread strategies utilized by state-sponsored attackers
Based on Walsh, China-sponsored actors like Salt Hurricane are “superior, persistent menace actors.” In contrast to ransomware teams, they don’t search instant monetary achieve, however “need entry to the delicate core elements of vital infrastructure, equivalent to telecommunications, for espionage and even harmful functions.”
“Their assaults will not be about locking down techniques and extracting fast income,” based on Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use tough strategies to get into vital infrastructure and keep there, doubtlessly 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 warned defenders in regards to the frequent strategies utilized by these state-sponsored menace actors.
Provide chain compromises
Compromising provide chains can act as a gateway to focus on networks, based on the ASD. The company famous, “Cyber provide chain danger administration ought to type a significant factor of a company’s general cybersecurity technique.”
Lifetime of the nation 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 objectives and evade detection by interfering with regular system and community actions.” These so-called “lifetime of the nation” strategies contain ready to steal data from a company’s community.
Cloud strategies
State-sponsored menace actors are adapting their strategies to take advantage of cloud techniques for espionage as organizations transfer to cloud-based infrastructure. The ASD mentioned that strategies for accessing a company’s cloud companies “embrace brute-force assaults and password spraying to achieve entry to extremely privileged service accounts.”

Methods to defend towards cyber threats
There are some similarities in menace actors’ strategies and the weaknesses within the techniques they exploit. The ASD mentioned state-sponsored cyber actors typically use beforehand stolen knowledge, equivalent to community data and credentials from previous cybersecurity incidents, to additional their operations and re-exploit community units.
Thankfully, firms can defend themselves from cyber assaults. Earlier this 12 months, TechRepublic consolidated knowledgeable recommendation on how companies can defend themselves towards the commonest cyber threats, together with zero-days, ransomware and deepfakes. These options embrace retaining software program updated, implementing endpoint safety options and growing an incident response plan.
