In today’s digital landscape, cybercriminals have increasingly turned to vulnerabilities in widely-used IT and security tools to launch devastating attacks. Recent incidents demonstrate how quickly these tools can become prime targets:

• Ivanti enterprise VPNs: A zero-day vulnerability was exploited to deploy the backdoor DSLog.
• TeamCity: Attackers from the APT29 group leveraged a remote code execution vulnerability to install malicious SSH certificates, execute DLLs, and maintain persistence through scheduled tasks.
• Fortra GoAnywhere MFT: Exploited by ransomware groups like LockBit and Cl0p to execute remote code, leading to significant attacks, particularly in the healthcare sector.

These examples highlight a growing trend—supply chain cyberattacks are becoming the preferred method for state-sponsored hackers and ransomware operators to infiltrate organizations.

Supply Chain Attacks: An Ongoing Concern

While recent headlines have brought supply chain vulnerabilities to the forefront, these attacks are not new. Hackers have long exploited weaknesses in third-party systems to breach target organizations.

• The SolarWinds Orion breach allowed attackers to infiltrate government and corporate networks through compromised software updates.
• The VMware Workspace ONE vulnerability was another reminder of how third-party tools can be leveraged for unauthorized access.
• The infamous RSA SecurID token breach resulted in attackers compromising sensitive systems at major organizations, including Lockheed Martin.

These incidents reveal the potentially catastrophic consequences of supply chain attacks, including operational disruption, reputational damage, and regulatory penalties. Organizations must move beyond basic vendor management to adopt proactive measures that address third-party risks head-on.

Seven Steps to Strengthen Supply Chain Cybersecurity

To mitigate supply chain risks, businesses need a comprehensive approach that integrates vendor oversight, robust internal processes, and cutting-edge technologies.

1. Advanced Supplier Risk Management

• Vet all suppliers and third-party vendors for compliance with cybersecurity standards like ISO 27001, NIST, or GDPR.
• Classify vendors based on the sensitivity of data they handle and the criticality of their services.
• Require suppliers to undergo independent software testing before deployment.

2. Secure the Software Development Pipeline

• Protect administrative access to DevOps tools and applications.
• Use secure configurations, manage secrets effectively, and authenticate services with high confidence.
• Extend security controls to microservices, cloud, and DevOps environments.

3. Regular Software and System Updates

• Ensure all systems—both internal and supplier-managed—are regularly updated and patched.
• Avoid using outdated or unsupported software that could introduce vulnerabilities.

4. Harden Your IT Environment

• Configure cloud environments to reject authorization requests with invalid tokens.
• For on-premises systems, deploy FIPS-validated Hardware Security Modules (HSMs) to securely store token-signing certificate private keys, reducing the risk of key theft.

5. Implement Strong Access Controls

• Limit vendor access to only the data and systems they need for their operations.
• Use multi-factor authentication (MFA) for all third-party access.
• Adopt a Zero Trust model, requiring continuous user verification before granting access.

6. Leverage Advanced Security Tools

• Use network segmentation to prevent lateral movement in case of a breach.
• Deploy Endpoint Detection and Response (EDR) solutions to identify malicious activities on third-party-connected devices.
• Encrypt sensitive data shared with suppliers, both at rest and in transit.
• Incorporate Business Continuity and Disaster Recovery (BCDR) solutions to ensure resilience against potential breaches.

7. Adopt Best Practices and Legal Safeguards

• Implement the NIST Cybersecurity Framework to manage threats effectively.
• Use supply chain-specific frameworks like ISO 28001 for supply chain security management.
• Include cybersecurity requirements in vendor contracts, such as breach notification obligations and mandatory third-party audits.

The Shift to Supply Chain Security

As direct attacks on networks become more challenging, cybercriminals are focusing on vulnerabilities in supply chains to gain backdoor access to systems. This shift underscores the need for organizations to actively manage IT security risks within their supply chains.

By adopting the strategies outlined here, businesses can mitigate these risks, reduce exposure to supply chain attacks, and build a stronger cybersecurity posture.
