Surviving the Era of Geopolitical Cyberattacks: A Five-Step Containment Strategy for CISOs
Geopolitical cyberattacks are becoming a major concern, with nation-state actors and politically aligned groups deploying destructive malware. The Iranian wiper campaign is a notable example of this trend, targeting organizations in critical supply chains, healthcare ecosystems, or national infrastructure. Destructive cyber campaigns often follow predictable operational patterns, which can be understood to limit damage even when attackers breach the perimeter. Attackers typically gain initial access through stolen credentials, conduct hands-on activity, move laterally using administrative tools, escalate privileges, and deploy wiping mechanisms simultaneously. Cyber resilience refers to an organization's ability to quickly adapt to and respond to cyber threats with minimal impact to its operations. To achieve cyber resilience, CISOs must adopt a comprehensive five-step containment strategy: stopping credential theft, preventing lateral movement, restricting privileged accounts, detecting unauthorized access paths, and containing destructive activity.
In a world where cybersecurity threats are increasingly becoming a major concern, the recent surge in geopolitical cyberattacks has raised significant eyebrows. Nation-state actors and politically aligned groups are now deploying destructive malware designed to cripple organizations and critical infrastructure, often with devastating consequences.
One notable example of this trend is the Iranian wiper campaign, which has been gaining attention in recent months. These attacks are designed to destroy systems, halt operations, and create cascading real-world consequences. They often target organizations that sit in critical supply chains, healthcare ecosystems, or national infrastructure.
For security leaders, the question is no longer just how to prevent intrusions—it is how to survive them. Recent incidents highlight the potential scale of these attacks. In March 2026, the Iran-linked group Handala attacked Stryker, a Fortune 500 manufacturer of medical technologies used in hospitals worldwide. The attackers reportedly wiped more than tens of thousands of devices across the company's global network, disrupting operations in 79 countries. Thousands of employees were impacted as manufacturing, order processing, and logistics slowed dramatically.
Despite the headlines, destructive cyber campaigns follow predictable operational patterns. When defenders understand those patterns, they can limit the damage—even when attackers successfully breach the perimeter.
Threat intelligence research into the Handala / Void Manticore cluster shows that many Iranian destructive campaigns rely heavily on manual operations rather than advanced malware. Attackers typically:
Gain initial access through stolen VPN credentials
Conduct hands-on activity inside the environment
Move laterally using administrative tools
Escalate privileges
Deploy multiple wiping mechanisms simultaneously
Operators frequently rely on tools already present in enterprise environments, including RDP, PowerShell remoting, WMI, SMB, and SSH. Because these tools are legitimate administrative utilities, attackers can often move across networks without triggering traditional malware detection systems.
Researchers have also observed operators establishing covert access paths using tunneling tools such as NetBird, enabling them to maintain persistent connectivity inside victim environments.
Stopping these campaigns therefore requires focusing on containment and internal control—not just perimeter defense. In this context, the concept of "cyber resilience" has emerged as a crucial aspect of modern cybersecurity.
Cyber resilience refers to an organization's ability to quickly adapt to and respond to cyber threats, with minimal impact to its operations. This involves implementing measures such as automated containment, identity-driven controls, and real-time visibility into system-to-system connectivity.
In order to achieve this level of resilience, CISOs must adopt a comprehensive five-step containment strategy:
Firstly, they should stop credential theft from becoming full network access. Most destructive campaigns begin with compromised credentials obtained through phishing, credential reuse, or access brokers. Organizations should implement identity-aware access controls rather than flat network connectivity. This involves enacting Multi-Factor Authentication (MFA) enforced when accessing administrative services, not just during VPN login.
Secondly, they should prevent lateral movement through administrative ports. Iranian operators frequently move laterally using standard administrative protocols already present in the environment. Organizations should default-deny policies for administrative ports and restrict access that opens only after verified authentication. Additionally, real-time visibility into system-to-system connectivity is crucial to detecting potential breaches early.
Thirdly, they should restrict privileged accounts to the systems they actually manage. Many environments still grant administrators broad access across large portions of the network. Organizations should segment privileged access based on role and environment, limiting administrators to the specific systems they manage. Continuously monitoring privileged access activity will also help identify potential security risks.
Fourthly, they should detect unauthorized access paths and tunnels. Recent threat intelligence reports show Iranian operators using tunneling tools to maintain covert connectivity inside victim networks. Defenders need visibility inside the network, including monitoring east-west connectivity, establishing baselines for administrative communication, and detecting unusual connection patterns or tunneling behavior.
Lastly, they should contain destructive activity before it spreads. When wiper malware begins executing, attackers often deploy multiple wiping mechanisms simultaneously to maximize damage. Organizations that survive destructive incidents focus on containment. Key capabilities include automated isolation of compromised systems, immediate restriction of administrative access paths, and rapid ring-fencing of affected hosts.
In conclusion, the recent surge in geopolitical cyberattacks highlights a crucial need for organizations to adopt comprehensive cybersecurity strategies. By understanding the predictable operational patterns of these attacks, defenders can limit damage even when attackers successfully breach the perimeter. The key capabilities of cyber resilience include automated containment, identity-driven controls, and real-time visibility into system-to-system connectivity.
By adopting these measures, CISOs can significantly reduce the impact of destructive attacks and ensure their organizations remain resilient in an era where geopolitical cyber conflict is increasingly spilling into cyberspace.
