5 Steps to Securing Your Supply Chain
How to Secure Your Supply Chain
As you know today’s business environment is hyperconnected, with your supply chain including manufacturers, suppliers, distributors, and retailers, all it takes is for the attacker to break through whoever is the weakest link in the chain. When this happens massive, high-profile supply chain attacks (everybody remembers SolarWinds, right?) occur, with massive consequences for everyone involved.
The complexity and interconnectivity of modern supply chains have exposed organizations like yours to a plethora of cyber threats that can disrupt operations, erode trust, and inflict severe economic damage. This article aims to give some actionable guidance on how to remediate these threats.
Three Recent Supply Chain Attacks
Before we discuss specific vulnerabilities in the supply chain, and how to remediate them, we are going to look at three recent high-profile cyberattacks that have exposed the vulnerabilities that exist when interdependent networks of suppliers, distributors, and customers are targeted by sophisticated threat actors. These incidents not only cause significant operational disruptions but also lead to severe financial and reputational damage, underscoring the urgent need for robust cybersecurity measures across all facets of the supply chain.
The SolarWinds Orion Attack
Overview: One of the most sophisticated and consequential cyberattacks in history targeted the SolarWinds Orion software, a widely used network management system. This supply chain attack began with the compromise of SolarWinds’ software development or update mechanism.
Method: Hackers, believed to be backed by a nation-state, infiltrated SolarWinds’ systems and inserted malicious code into the Orion software updates. This malware, known as SUNBURST, was then unwittingly distributed to approximately 18,000 customers as they updated their systems, including major corporations and government agencies across the world.
Impact: The attackers gained access to the networks of numerous high-profile victims, including U.S. government departments such as the Treasury, the Department of Homeland Security, and the Department of Commerce. The breach was significant not only due to its scale but also because of the duration during which the attackers had access to sensitive data.
The Kaseya VSA Attack
Overview: Kaseya , a company that provides IT management software for MSPs (Managed Service Providers), was targeted in a ransomware attack that affected its VSA software—a tool used by MSPs to manage and monitor computers remotely.
Method: Cybercriminals exploited vulnerabilities in the VSA software to deploy the REvil ransomware across Kaseya’s customer base, which primarily included MSPs and, through them, the businesses they supported. This indirect approach allowed the attackers to amplify the impact of the ransomware by affecting not just one network but potentially hundreds through each MSP.
Impact: The attack led to the shutdown of thousands of businesses globally, with attackers demanding a $70 million ransom in bitcoin to release the decryption tool. This incident highlighted the cascading effects of supply chain attacks on interconnected networks and the devastating impact of ransomware when coupled with supply chain vulnerabilities.
The NotPetya Attack
Overview: NotPetya was initially perceived as a straightforward ransomware attack but was later identified as a state-sponsored cyber weapon aimed primarily at Ukraine. It spread far beyond its initial targets, affecting businesses worldwide.
Method: The attack began by compromising a popular Ukrainian accounting software called M.E.Doc. The attackers used a backdoor in a software update mechanism to distribute the malware, which then leveraged common administrative tools within Windows environments to spread across networks.
Impact: NotPetya caused extensive damage estimated at $10 billion, affecting global corporations such as Maersk, Merck, FedEx, and many others. Unlike typical ransomware designed for financial gain, NotPetya aimed at disruption and destruction of data, illustrating how geopolitical motivations can underpin cyberattacks and result in widespread collateral damage in global supply chains.
Vulnerabilities in Supply Chain Security
The first step in securing a supply chain is acknowledging the vulnerabilities that make it susceptible to cyber threats. Supply chains are inherently complex networks involving multiple stakeholders—manufacturers, suppliers, distributors, and retailers—all of which contribute to potential security gaps. These vulnerabilities may arise from various sources, including but not limited to, outdated technology systems, lack of standardized security protocols across the chain, insider threats, and inadequate monitoring of access points.
Technological Disparities: Often, not all entities in the supply chain are operating on the same technological level. Smaller suppliers might use legacy systems that lack the latest security measures, making them easy targets for cyber attacks. This disparity creates uneven risk levels throughout the supply chain, requiring a comprehensive approach to technology management and updates that ensure consistency and security across all nodes.
Standardization Challenges: While your organization might enforce strict cybersecurity measures, your suppliers and partners might not adhere to the same high standards, exposing your supply chain to risks. The lack of standardized security protocols can lead to vulnerabilities that are difficult to detect and manage. Implementing uniform security measures across all parties is crucial, but it is also challenging due to varying capabilities and resources among involved parties.
Insider Threats: The human element in supply chains can often be the most unpredictable factor. Insider threats—whether unintentional or malicious—are a significant risk. These threats can stem from employees within your own organization or from those working for suppliers and partners. Comprehensive background checks, continuous training on security practices, and a clear policy on data access and control are essential to mitigate this risk.
Access Point Exploitations: Every participant in the supply chain network potentially adds new access points for cyber threats. From software interfaces used for inventory management to third-party services for logistics and transportation, each connection point can be an entry for cyber-attacks if not properly secured. It is imperative to conduct regular audits of how information flows across these points and implement strict access controls and encryption to protect data integrity and confidentiality.

Building a Resilient Supply Chain Ecosystem
The final step in securing a supply chain goes beyond simply employing reactive measures and requires a focus on the proactive prevention of supply chain attacks. This broader perspective ensures not only defense against current threats but also preparation for future challenges. Here are five steps that your organization can take in order to create a resilient supply chain ecosystem:
Proactive Third-Party Vendor Assessment
Before onboarding and periodically thereafter, conduct thorough assessments of third-party vendors to identify any potential security risks:
Implement Advanced Cybersecurity Technologies
Investing in cutting-edge cybersecurity technologies is essential for detecting and responding to threats swiftly. Key tools include:
Enhance Supply Chain Visibility
Increasing the visibility of every link in the supply chain is crucial for identifying and mitigating risks:
Foster a Security-Centric Culture
Building a collaborative security culture across the supply chain enhances overall protection:
Focus on Supply Chain Awareness: Implement regular training and workshops tailored specifically to supply chain security, educating all stakeholders on recognizing and mitigating supply chain threats. Establish secure and open communication channels for prompt reporting of vulnerabilities, enhancing collective preventive measures.
Develop a Coordinated Incident Response Plan
A comprehensive incident response plan is critical for minimizing the impact of a breach:
Incident Response Plan for Supply Chain Threats: Create and regularly update a comprehensive incident response plan focused on supply chain disruptions. This plan should outline clear containment and mitigation procedures, ensure effective communication among all stakeholders, and include thorough post-incident analysis to strengthen future responses. Regular drills should be conducted to test the plan against potential supply chain threats.
By implementing these strategies, you can ensure that your organization not only manages current cybersecurity risks but also builds a resilient supply chain capable of withstanding and adapting to the dynamic threat landscape. Ultimately, the goal is to create a secure, reliable, and resilient supply chain that supports sustained business growth and fosters long-term partnerships based on trust and mutual security objectives.
