Discover how threat actors exploit the critical CVE-2026-20127 Cisco SD-WAN vulnerability. Learn IoCs, remediation steps, and how penetration testing secures your network.
The Australian Cyber Security Centre has issued urgent warnings about actively exploited vulnerabilities in Microsoft SharePoint Server (CVE-2025-53770) that enable unauthenticated remote code execution. With Chinese state-aligned actors and ransomware groups already compromising Australian organisations, this threat represents an immediate and severe risk to business-critical data and infrastructure.
Across AWS, Google Cloud, and Microsoft Azure environments in Australia and globally, 59% of IAM users maintain access keys that have never expired—credentials that have been active for more than one year. These long-lived credentials represent a silent but catastrophic vulnerability in your cloud infrastructure. This blog explores why long-lived credentials have become the primary attack vector for identity-based breaches, how red teams exploit them during penetration tests, and what you must do today to eliminate this ticking time bomb.
Critical authentication bypass vulnerabilities in Fortinet FortiGate and related products (CVE-2025-59718 and CVE-2025-59719) are now under active attack, allowing "ghost" SSO logins that completely sidestep normal controls and logs. For Australian organisations, this is more than a VPN or firewall problem – it is a board-level exposure that directly tests whether your external penetration testing, internal penetration testing, and red team assessment services are capable of simulating SSO abuse, identity takeovers, and lateral movement across hybrid networks.
A new security flaw called React2Shell (CVE-2025-55182) puts Australian businesses at extreme risk. It has a severity score of CVSS 10.0, which is the highest possible rating. This flaw lets hackers take full control of your servers without needing a password. It affects the popular tools React and Next.js.
As we close out the third week of February 2026, the Australian cyber landscape is being defined by a sophisticated pivot towards AI-enabled API exploitation and high-impact ransomware campaigns targeting the FinTech and Healthcare sectors. The "blast radius" of AI systems is widening, with the Model Context Protocol (MCP) emerging as a critical new attack surface.
This week in Australian cyber security, the threat landscape is dominated by critical zero-day exploitations affecting widely used infrastructure. Federal agencies and private sector organisations are on high alert following CISA’s inclusion of new vulnerabilities in the Known Exploited Vulnerabilities (KEV) catalogue. Locally, the healthcare sector remains under intense scrutiny following the release of a concerning audit of NSW Health’s cyber posture, while SaaS and AI-driven threats continue to evolve.
The first week of February 2026 has seen a distinct escalation in targeted campaigns against Australian critical infrastructure and services. This week’s intelligence highlights a sophisticated pivot by threat actors towards human-led attacks on identity systems (SSO) and a resurgence of high-impact ransomware claims in the healthcare sector. Furthermore, critical vulnerabilities in widely used SaaS and collaboration tools demand immediate attention from security teams across the region.
The last seven days (26 January – 02 February 2026) have been defined by a resurgence in high-criticality infrastructure vulnerabilities and evolving nation-state tradecraft. For Australian organisations, the immediate priority is addressing active exploitation of Ivanti Endpoint Manager Mobile (EPMM) zero-days and critical patches for Cisco network infrastructure. Simultaneously, the threat landscape is shifting with reports of North Korean APT groups restructuring their operations, while the healthcare sector faces renewed warnings regarding IT/OT convergence risks.
Welcome to this week's threat briefing. As we settle into 2026, the Australian cyber landscape is already heating up with critical exploits targeting the very automation tools that drive our efficiency. From unauthenticated remote code execution in popular workflow platforms to the industrialisation of AI jailbreaking, this week has highlighted that "set and forget" is no longer a viable security strategy.
As we settle into 2026, the Australian cyber threat landscape shows no signs of slowing down. The transition from December 2025 to January 2026 has been characterised by a volatile mix of critical infrastructure vulnerabilities and aggressive ransomware campaigns targeting the "edge" of corporate networks. This week, we have observed a sharp escalation in the exploitation of database and API vulnerabilities, alongside targeted attacks on the healthcare and education sectors.
As we approach the end of 2025, the Australian cyber threat landscape has experienced a volatile week, with significant incidents rocking the education and healthcare sectors. The last seven days have been defined by the active exploitation of critical vulnerabilities in modern web frameworks and a series of ransomware attacks targeting sensitive patient and staff data. This week’s briefing highlights a major data breach at the University of Sydney, a ransomware attack on fertility provider Genea, and the "React2Shell" vulnerability that is currently reshaping cloud security priorities.
The Australian cyber security landscape has experienced a turbulent week (7–14 December), dominated by a "Critical" alert from the Australian Cyber Security Centre (ACSC) regarding widespread vulnerabilities in edge devices and a worrying escalation in AI-assisted development flaws. As we approach the holiday shutdown period—a traditional window for heightened ransomware activity—organisations across Healthcare, Government, and FinTech must urgently prioritise patching and detection. Here is your deep dive into the threats impacting Australian organisations this week.
This week has seen a critical escalation in the Australian cyber threat landscape, dominated by a maximum-severity vulnerability in a widely used web framework and significant breaches in the Defence and Education sectors. The Australian Cyber Security Centre (ACSC) has issued urgent alerts, and organisations across all sectors—particularly those using React-based web applications—must take immediate action. Here is your deep dive into the threats, incidents, and vulnerabilities shaping the last 7 days (01–07 December 2025).
This week has seen a significant escalation in cyber activity targeting Australian critical infrastructure and supply chains. The most alarming development is a confirmed breach of a major Defence contractor, potentially exposing sensitive naval data. Simultaneously, a sophisticated campaign by the "Scattered Lapsus$ Hunters" group is aggressively targeting SaaS platforms, with Qantas and Zendesk users in the crosshairs. As we approach the holiday season, a new report warns that ransomware operators are leveraging Generative AI to time attacks for weekends and public holidays, specifically targeting periods of reduced staffing in Security Operations Centres (SOCs).
