Australian businesses didn’t verify whether or not Salt Hurricane has reached Australian telco firms. Nonetheless, Grant Walsh, telco trade lead at native cyber safety agency CyberCX, wrote that it was “unlikely the ACSC – and accomplice businesses – would difficulty such detailed steerage if the menace was not actual.”

“Telco networks have invested in a number of 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, notably these related to China.”

Salt Hurricane: A part of a wider state-sponsored menace 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, 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 looking for to place themselves on data and communications expertise networks for disruptive cyberattacks towards U.S. essential infrastructure within the occasion of a significant disaster.

The ASD famous that Australian essential infrastructure networks might be susceptible to related 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 looking for to pre-position on networks for disruptive cyber assaults,” the ASD wrote within the report.

Nonetheless, it stated that state-sponsored cyber actors even have information-gathering and espionage aims 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 typically maintain giant portions of knowledge, so are seemingly a goal for such a exercise.”

Widespread strategies utilized by state-sponsored attackers

In accordance with Walsh, China-sponsored actors like Salt Hurricane are “superior persistent menace actors.” Not like ransomware teams, they aren’t looking for rapid monetary achieve however “need entry to the delicate core elements of essential infrastructure, like telecommunications, for espionage and even damaging functions.”

“Their assaults usually are not about locking up techniques and extracting quick earnings,” in accordance with Walsh. “As an alternative, these are covert, state-sponsored cyber espionage campaigns that use hard-to-detect strategies to get inside essential infrastructure and keep there, probably for years.

How you can defend towards 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 typically use beforehand stolen information, resembling community data 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 expert advice on how companies can defend themselves towards the commonest cyber threats, together with zero-days, ransomware, and deepfakes. These ideas included protecting software program up-to-date, implementing endpoint safety options, and creating an incident response plan.
