CEO CYBER SECURITY ALERT BULLETIN
Global Conflict Escalation – Immediate Cybersecurity Review Required for Organisations in Australia, New Zealand, the Pacific and Global Markets
Issued for: CEOs, Board Directors, CIOs, CISOs and Business Leaders
Region: Australia | New Zealand | Pacific Islands | Global Markets
Alert Level: Elevated Cyber Risk
Executive Brief
Rising geopolitical tension in the Middle East is increasing cyber risk for organisations well beyond the conflict zone. Australian government guidance for boards now warns that Australia faces a heightened cyber threat environment linked to tensions in the Middle East, Ukraine and the Indo-Pacific, with state-based actors capable of positioning for disruptive attacks against critical infrastructure and services.
That risk does not sit with the government alone. Commercial organisations are often hit during periods like this, either as direct targets, soft-entry points, or collateral damage. Attackers use the confusion that follows global instability to step up ransomware, credential theft, disruption campaigns and attacks through suppliers.
The ACSC Essential Eight was built to reduce exposure to exactly these kinds of common attack paths, including ransomware, business email compromise and destructive activity.
For organisations across Australia, New Zealand and the Pacific, this is a practical business risk. It affects uptime, customer trust, compliance, cash flow and board accountability. This is the time to confirm what is exposed, what is weak and how fast your team can respond.
This is where structured cybersecurity testing, advice from Essential Eight security auditors, and a ready cyber incident response team become critical.
How to manage supply chain cyber risks in Olympic IT ecosystems.
Key Cyber Threats CEOs Should Expect
As global tensions rise, cyber threats often become more frequent, more targeted, and more disruptive. Business leaders should understand the most likely attack methods and where their organisation may be exposed. A clear view of these threats helps CEOs make faster decisions and direct resources where they matter most.
1. Ransomware Attacks Targeting Businesses
Cybercriminal groups often use periods of instability to increase ransomware activity. They look for weak remote access, unpatched systems, over-privileged accounts and poor backup practices. The ACSC continues to stress backups, access controls and timely patching as core protections against ransomware.
Businesses most at risk include:
• Financial institutions
• Telecommunications providers
• Healthcare organisations
• Logistics and shipping companies
• Data centres and cloud providers
A successful ransomware event can stop operations for days, affect customer service, trigger legal reporting obligations and damage reputation long after systems come back online.
2. Credential Theft and Identity Compromise
Phishing, business email compromise and information theft remain some of the easiest paths into a business. Senior executives are especially attractive targets because they hold broad access, financial authority and influence over key decisions. The ACSC continues to promote strong account security controls such as multi-factor authentication to reduce account compromise risk.
Once an attacker gets valid credentials, they can move quietly. In many cases, the first sign of trouble is suspicious email activity, unusual logins or a demand for payment.
3. Exploitation of Unpatched Systems
Attackers move quickly when new vulnerabilities appear. Internet-facing assets such as VPN gateways, remote access services, web applications, cloud workloads and network devices are often first in line.
Common targets include:
• VPN gateways
• Remote access systems
• Web applications
• Cloud environments
• Network infrastructure devices
The Essential Eight places strong emphasis on patching applications and operating systems because delayed patching leaves known holes open for attack. Good cybersecurity testing should confirm not only whether patches exist, but whether high-risk exposures remain reachable from the internet.
4. Supply Chain Cyber Attacks
Many organisations are better protected than the vendors they rely on. That is why attackers increasingly go after managed service providers, software vendors, cloud platforms and outsourced IT partners. ACSC guidance on managing cyber supply chains makes clear that supplier risk is now a key part of business resilience.
Businesses should be particularly cautious of risks associated with:
• Managed service providers (MSPs)
• Software vendors
• Cloud platforms
• IT outsourcing providers
A supplier compromise can spread fast across customer environments, especially where third-party access is broad and poorly monitored.
5. Data Destruction and Cyber Sabotage
Not every attacker wants money. Some want disruption. State-linked groups and other advanced actors have used destructive malware and sabotage techniques to wipe systems, damage trust and delay recovery. The Essential Eight maturity guidance also warns that malicious actors may destroy data, including backups, when privileged access is available.
If your business has not tested restoration, failover and crisis decision-making under pressure, recovery may take far longer than expected.
Immediate Cybersecurity Actions CEOs Should Initiate
In periods of heightened global tension, waiting to act can leave serious gaps exposed. CEOs should focus on a few immediate steps that reduce risk, improve visibility, and support faster response if an incident occurs. These actions help leadership teams move from general concern to practical readiness.
1. Conduct an External Attack Surface Review
Make sure your organisation knows exactly what is visible from the internet. That includes forgotten systems, old remote access points, shadow IT and exposed test environments. Review:
• Internet-facing infrastructure
• Cloud environments
• Remote access gateways
• Exposed APIs and web services
A clear view of your external attack surface is the starting point for reducing avoidable cyber risk. When organisations know what is exposed, they can fix weaknesses sooner, close unnecessary access points, and strengthen their overall security posture.
2. Enforce Strong Identity and Access Controls
Confirm that:
• Multi-Factor Authentication (MFA) is enabled across all systems
• Privileged accounts are tightly managed
• Dormant or unused accounts are removed
• Third-party access is strictly controlled
This is also the right time to ask whether privileged accounts are separated, monitored and reviewed. Many serious breaches expand because access controls were too broad for too long.
3. Verify Patch Management and Vulnerability Exposure
Your CIO or CISO should confirm:
• Critical security patches are deployed quickly
• External vulnerability scanning is conducted regularly
• Independent penetration testing is performed annually
This should not be treated as a tick-box task. It should include ongoing cybersecurity testing, validation of internet-facing systems and review by Essential Eight security auditors where the business needs assurance against ACSC-aligned controls.
4. Validate Ransomware Recovery Capability
Boards should ensure the organisation has:
• Secure offline backups
• Tested disaster recovery plans
• Documented incident response procedures
• Cyber insurance coverage verified
Ask for evidence, not assumptions. Can backups be restored quickly? Are they isolated? Has the plan been tested with executives present? A prepared cyber incident response team should already know roles, escalation paths and decision points before an event begins.
5. Review Supply Chain Cyber Risk
Conduct immediate risk reviews for:
• Technology vendors
• IT service providers
• Software platforms
• Cloud infrastructure providers
Supply chain compromise is now one of the fastest-growing attack methods. Contracts, access rights, logging, breach notification terms and offboarding controls should all be reviewed. In many cases, Essential Eight security auditors can help identify whether supplier-connected systems are undermining your own maturity targets.
What every business must prepare for in 2026.
Critical Questions CEOs Should Ask Today
In a high-risk environment, the right questions can reveal weaknesses faster than assumptions ever will. CEOs should use this moment to challenge preparedness, response capability, and executive visibility over cyber risk. Clear answers to these questions can help leadership teams act early and reduce the chance of being caught off guard.
• If our network was breached tonight, how quickly would we detect it?
• Do we have a tested cyber incident response plan?
• When was our last independent penetration test conducted?
• Are our backups protected against ransomware?
• Is cyber risk actively monitored and reported at the board level?
One more question matters just as much: who owns the decision-making in the first hour of a crisis? A skilled cyber incident response team can contain technical damage, but executive clarity decides how well the business holds together.
Industries at Elevated Risk in the Region
Organisations operating in the following sectors should be particularly vigilant:
• Financial services
• Telecommunications
• Energy and utilities
• Healthcare
• Government services
• Logistics and transportation
• Data centres and cloud infrastructure
These sectors carry high operational value and often support critical services. That makes them attractive targets for both criminal and state-linked actors. Australian board guidance specifically highlights the need for stronger preparedness in this environment.
Strategic Advisory for Boards and Executives
Cyber conflict now moves alongside geopolitical conflict. Businesses with weak cyber hygiene, weak governance or untested response capability can be caught in the path of broader campaigns.
Boards should treat cyber security as part of enterprise risk, not just IT operations. That means regular reporting, scenario testing, ownership at executive level and practical assurance over the controls that matter most.
Recommended Immediate Action
Organisations should consider commissioning an independent cybersecurity posture review covering:
• External attack surface assessment
• Penetration testing
• Incident response readiness
• Supply chain security review
• Compliance with recognised frameworks such as – ISO 27001, NIST Cybersecurity Framework, Essential Eight (Australia)
A strong review should combine technical findings, governance gaps and clear remediation priorities. It should also involve Essential Eight security auditors where ACSC alignment is required.
CEO Advisory
Periods of geopolitical instability rarely remain confined to physical battlefields. Today, cyber operations are one of the first and most effective instruments used to disrupt economies, organisations, and critical infrastructure.
For business leaders across Australia, New Zealand and the Pacific, the question is no longer if cyber threats will intensify during global conflict — but whether your organisation is prepared when they do.
Boards and executive leadership must ensure cybersecurity is treated as a strategic risk management priority, embedded into governance, operational resilience, and business continuity planning.
Organisations that act early will protect their operations, reputation, and stakeholders. Those that delay may find themselves responding to a crisis instead of preventing one.
