Cybersecurity in 2026 is already playing out locally
Early 2026 is already reinforcing the same weaknesses Australian organisations struggled with last year. That matters more than how many incidents have appeared so far.
Since mid December, an Australian telecommunications provider (Netstar) has appeared on a ransomware leak site following alleged data theft. In the final days of 2025, two cyber professionals pleaded guilty after operating a ransomware scheme tied to BlackCat. On the first day of January, a researcher disclosed a serious vulnerability affecting an Australian government system and the response focused on fixing the issue rather than disputing it.
These incidents are not connected. But they’re useful because they point to the same underlying issues.
Ransomware remains a pressure tactic
Netstar appears on a ransomware leak site following alleged data theft.
Netstar is a Melbourne based telecommunications provider that services businesses rather than consumers. That matters when you look at the type of data alleged to have been taken.
According to reports, the data linked to the ransomware listing includes customer information and internal business records. This is the kind of data that creates follow on problems well into 2026, after systems have been recovered and operations are back to normal. It affects contracts, supplier relationships and trust with customers who rely on those services daily.
For organisations like this, the impact is rarely about downtime alone. The real pressure comes from having to explain what information was accessed, who it relates to and what the downstream consequences might be. Those questions won’t wait until systems are fully restored.
Trusted access is still being abused
Cyber professionals plead guilty after operating BlackCat ransomware scheme.
In late December, Ryan Goldberg, 40, of Georgia and Kevin Martin, 36, of Texas pleaded guilty to operating a ransomware scheme linked to the BlackCat group. Both had worked in incident response roles and used that experience to help deploy ransomware and negotiate extortion payments. Court documents show they targeted organisations in the medical and engineering sectors and extorted close to $2m in crypto.
The activity relied on insider knowledge of incident response processes and on understanding how organisations behave under pressure. For security teams, it shows that access and authority need ongoing oversight. People with expert technical knowledge can also misuse that knowledge when controls around access are weak.
Government systems remain a target
Vulnerability in a Department of Foreign Affairs and Trade website identified and reported through responsible disclosure
On the 1st of January, reporting confirmed that a critical vulnerability affecting an Australian government system had been identified and disclosed. The issue involved a Department of Foreign Affairs and Trade website and was addressed after being reported through the appropriate channels.
The vulnerability was identified by an experienced security researcher as part of a visa application process, using legitimate testing methods. Rather than being exploited or monetised, the issue was reported directly and fixed quickly.
It also tells us that our government systems are still exposed enough to be found by skilled external researchers. At the same time, when vulnerabilities are identified through proper testing and handled correctly, like they were in this instance, they can be resolved without escalation.
What this confirms as 2026 begins
These incidents reflect the same cyber issues Australian organisations have been navigating for some time. Ransomware pressure continues to focus on data exposure. Trusted access remains a risk when oversight is weak. Government systems face discovery risks similar to those seen in the private sector.
What changes outcomes is how access is managed, how issues are surfaced and how quickly organisations act once a problem is identified. Early 2026 is already showing that addressing vulnerabilities early is the only way to block extortion.
