Growing Cyber Threat: Is Your Supply Chain Secure?

In today’s interconnected world, cyber security is no longer just an internal issue within your organisation; it’s a supply chain imperative. The wider implications and effects of supply chain on the security of your organisation from a cyber threat perspective are continually growing. As organisations become increasingly dependent on third-party vendors, partners, and suppliers, the risks associated with cyber security in the supply chain have become a significant priority. While large companies may have fortified their internal defences, the security vulnerabilities of their suppliers – especially those in tiers 2 and 3 – pose significant risks.

The threat landscape is evolving, and supply chain attacks are becoming more prevalent, often causing severe disruptions to business operations and leading to financial loss, reputational damage, and even national security risks. In this article, we explore why supply chains are a growing target for cybercriminals and how businesses can mitigate these risks.

Why Supply Chains Are Prime Targets

Supply chains have become increasingly complex and interdependent. A typical supply chain might involve hundreds or even thousands of vendors across different sectors, geographies, and security maturity levels. This complexity introduces numerous points of entry for cyber attackers.

One of the main reasons supply chains are targeted is due to the interconnected ecosystems that businesses operate within. Attackers understand that while larger companies may have strong cyber security defences, their suppliers might not. By infiltrating a small or medium-sized supplier, criminals can gain access to the larger organisations they work with, exploiting the weakest link to achieve their goals.

For instance, in June 2024, a financially motivated ransomware group attacked Synovis, a third-party provider of pathology services, which subsequently impacted NHS trusts and GPs in south-east London. The attack resulted in the postponement of more than 1,000 operations and over 3,000 outpatient appointments. This example demonstrates the severe consequences of a supply chain breach to the general public and not just the target organisation.

Geopolitical tensions and global events, such as the COVID-19 pandemic, have exacerbated these risks. As the world moved to remote work and digital transformation accelerated, the attack surface expanded, making it easier for cybercriminals to exploit vulnerabilities within supply chains. Nation-state actors, cyber criminals, and hacktivists have leveraged these disruptions to target supply chains with ransomware, phishing, and other malicious attacks.

Who Are the Cyber Threat Actors?

Cyber threat actors can vary widely, ranging from nation-state hackers to cyber criminal groups. These actors have different motivations but share a common goal: exploiting vulnerabilities to steal sensitive data, disrupt operations, or gain financial profit.

1. Nation-State Actors: These are government-sponsored groups that engage in cyber espionage, surveillance, and sabotage to advance their national interests. They often target critical infrastructure, intellectual property, and sensitive corporate data. For example, during the ongoing Russia-Ukraine conflict, we have seen a surge in nation-state cyber activity, targeting financial services and government agencies.
2. Cyber criminals: These actors are typically motivated by financial gain. They engage in activities such as ransomware attacks, fraud, and data theft. Their primary goal is to monetise stolen data or extort payments from affected organizations.
3. Insider Threats: Current or former employees, contractors, or partners who misuse their access to an organisation’s systems and data, either maliciously or negligently, pose a significant risk. These threats are often harder to detect and can lead to severe data breaches or other security incidents.
4. Hacktivists: Individuals or groups driven by ideological, political, or social motivations use cyber attacks to promote their cause. These attacks may include website defacements, data leaks, and disruption of services.

The Impact of Cyber Attacks on Supply Chains

The consequences of a cyber attack on a supply chain can be devastating. Beyond the immediate financial losses, organisations face significant operational disruptions, legal and regulatory penalties, and long-term reputational damage.

Consider the case of the Ministry of Defence in the UK, where a payroll supplier breach exposed the personally identifiable information (PII) of 272,000 current and former British military personnel. Such breaches not only harm the organisation but can also compromise national security.

In another example, the 2024 attack on United Healthcare Group by the ALPHV ransomware group affected over 3,000 organizations and compromised the data of more than 150 million patients, with an estimated cost of $6.5 billion. This case underscores the widespread impact that a single supply chain breach can have across multiple organisations.

How to Secure Your Supply Chain

Given the growing risks, securing your supply chain against cyber threats requires a proactive and multi-layered approach. Here are some key strategies that organisations can implement:

1. Thorough Vendor Assessments: Before engaging with a new supplier, it’s critical to assess their cybersecurity practices. This can be done through security questionnaires, third-party audits, or certifications. Using platforms like Achilles, organisations can map their supply chain and establish a baseline level of security for all vendors.
2. Continuous Monitoring: Cyber threats are constantly evolving, which is why continuous monitoring of your supply chain is essential. Solutions like the Orpheus platform provide real-time visibility into the cyber exposure of your suppliers, allowing you to detect and respond to threats more effectively.
3. Regular Security Audits and Assessments: Conducting regular security audits and assessments helps identify vulnerabilities in both your internal systems and those of your supply chain partners. Periodic vulnerability assessments and penetration testing can validate the effectiveness of your security measures.
4. Strong Contractual Security Requirements: Ensure that your contracts with vendors include specific cybersecurity requirements. This could involve adherence to security protocols, regular reporting of incidents, and compliance with industry standards.
5. Prioritise Critical Vendors: Not all suppliers pose the same level of risk. Focussing your efforts on high-risk vendors that have access to critical systems or sensitive data. This helps you allocate your resources more effectively.
6. Implement Basic ‘Cyber Hygiene‘: Even smaller organisations with limited resources can improve their cybersecurity posture by implementing basic practices, such as regular software updates, employee training, and enforcing strong password policies.

The Path Forward: A Comprehensive Approach

As supply chain cyber attacks become more frequent and sophisticated, organisations must take a comprehensive approach to cyber security. This involves not only securing your own systems but also ensuring that your entire supply chain adheres to robust security practices. From conducting thorough vendor assessments to leveraging continuous monitoring tools, businesses must be proactive in mitigating the risks posed by cyber threats.
