This week, the cyber security spotlight has shifted from isolated incidents to a complex web of interconnected risks—where a single vulnerability or third-party misstep can ripple across industries and borders. From high-profile SaaS breaches to critical infrastructure exposures, Australian organisations are being reminded that digital trust is built not just on technology, but on the strength of every link in the business ecosystem. As attackers innovate and regulatory scrutiny intensifies, the ability to anticipate and adapt to these evolving threats is now a defining factor in operational resilience.
This week, Australian organisations have faced a surge in diverse and sophisticated threats. Critical vulnerabilities have been actively exploited in widely-used enterprise software, notably Fortinet’s FortiWeb and Oracle Identity Manager, both now listed in the CISA Known Exploited Vulnerabilities Catalog. The Cl0p ransomware group leveraged a zero-day in Oracle E-Business Suite, impacting major brands like Logitech and Cox Enterprises. Third-party supply chain breaches have also struck global SaaS platforms, with adversaries exploiting OAuth token weaknesses to compromise nearly 1,000 Salesforce-linked organisations. API and cloud management vulnerabilities continue to threaten user data integrity, as seen in the scraping of 3.5 billion WhatsApp user accounts and research revealing IoT devices can be remotely compromised through static identifier impersonation.
Locally, the Optus fine for third-party identity verification failures exposed customers to fraudulent mobile porting and direct financial losses. A four-hour Cloudflare outage highlighted the vulnerabilities of internet infrastructure centralisation, impacting sites like Canva, X, and ChatGPT, and presenting systemic risk to interconnected Australian digital services.
This week’s vulnerability landscape is marked by critical flaws in both software and hardware. Fortinet’s FortiWeb and Oracle Identity Manager vulnerabilities have enabled attackers to seize control of devices and compromise authentication flows. Grafana’s SCIM interface suffered from a privilege escalation flaw, while Google Chrome patched a critical type confusion bug already exploited in the wild. The Ray AI framework and 7-Zip also faced remote code execution vulnerabilities, prompting swift advisories. Industrial control systems, including products from Schneider Electric, Shelly, Opto 22, and Festo, were patched amidst advisories from CISA.
For business leaders, these vulnerabilities represent more than technical debt—they are liabilities that can disrupt operations, erode trust, and expose sensitive data. Every bridge and tunnel in your digital city must be regularly inspected and reinforced.
Ransomware and data breach incidents have continued to escalate. Cox Enterprises and Logitech confirmed breaches stemming from exploitation of a zero-day vulnerability in Oracle E-Business Suite, with the Cl0p ransomware group responsible. Iberia Airlines suffered a third-party supplier breach, while Salesforce customers were targeted by the ShinyHunters group through compromised OAuth tokens in third-party apps. Insider threats remain a concern, highlighted by a CrowdStrike staff member leaking sensitive information to hackers. Akira ransomware continues to exploit VPN weaknesses, targeting sectors reliant on sensitive data. Locally, Optus was fined $826,000 after scammers exploited verification system flaws to hijack customer identities and access bank accounts, illustrating ongoing risks from both internal failures and third-party vendors.
Nation-state and APT campaigns have intensified, spanning both espionage and hybrid cyber-kinetic threats. China-linked APTs have covertly targeted Russian IT contractors and exploited software update infrastructure in Chinese organisations. In Taiwan and Southeast Asia, APT24 advanced espionage through new custom malware and exploited WinRAR and Office vulnerabilities as part of broad supply chain attacks. Iran’s UNC1549/Imperial Kitten group escalated targeting of aerospace and defence sectors, leveraging third-party supplier compromise, spear phishing, credential theft, and custom backdoors. These operations highlight increasing sophistication, blending long-term persistence with lateral movement, supply chain compromise, and physical-world impact.
Recent supply chain and third-party security incidents highlight persistent and evolving risks for enterprises globally and in Australia. Cox Enterprises and Logitech suffered breaches after threat actors exploited zero-day vulnerabilities in Oracle E-Business Suite, with Cl0p ransomware responsible for exfiltrating vast amounts of corporate data. Iberia Airlines disclosed a significant data breach caused by supplier vulnerabilities, underlining the recurring risk of third-party compromise leaking customer information. Salesforce and its customers faced attacks via abused OAuth tokens in connected third-party apps, resulting in unauthorised access to around 1,000 organisations’ data. Locally, Optus was fined for deficiencies in its identity verification process, exploited by scammers through a third-party platform.
These incidents underscore the escalating complexity and consequence of poor third-party security posture. Organisations are urged to intensify scrutiny of vendor security and integrate continuous monitoring and rapid incident response into their supply chain management processes.
Phishing, social engineering, and credential theft campaigns have employed increasingly sophisticated techniques. The Sneaky 2FA phishing kit added Browser-in-the-Browser capabilities, allowing convincing Microsoft credential theft with pop-up simulations. Fake OAuth compromises targeting Salesforce led to data breaches through third-party applications. Social engineering remains a critical attack vector, as demonstrated in the WhatsApp “HackOnChat” campaign, where linked-device features and session hijacking enabled widespread account takeovers. LinkedIn emerged as an attack surface with China-backed recruitment spear-phishing aimed at lawmakers and executives. Browser notifications were weaponised via Matrix Push and Push C2, delivering phishing and credential-stealing payloads while bypassing traditional endpoint security.
Locally, Optus customers were exposed when scammers exploited weaknesses in the identity verification process to port phone numbers and access banking credentials, prompting an $826,000 fine by ACMA and underscoring third-party weaknesses.
To keep your digital city safe, business leaders should act decisively:
This week’s developments show that the digital city is under constant threat, with adversaries probing for weaknesses at every turn. By embracing a proactive, strategic approach—reinforcing defences, patching vulnerabilities, and fostering a culture of security—Australian businesses can transform their organisations from vulnerable targets into resilient fortresses.
