Securing supply chains against cyber threats: The role of email security

By Cian Fitzpatrick | 12th December 2024

Supply chains are intricate ecosystems of interconnected organisations working together to deliver goods and services we rely on every day.

While these networks drive efficiency, their increasing complexity and reliance on digital communication make them prime targets for cyberattacks. For businesses managing supply chains, securing communication channels, particularly email, is paramount to safeguarding sensitive data and maintaining operational resilience. It cannot be overstated that email security for supply chains needs to be an essential focus for firms operating in this space.

Topsec is at the forefront of supply chain cybersecurity, offering cutting-edge solutions to protect organisations from email-based threats. By leveraging advanced technologies and proven protocols, Topsec ensures that businesses remain resilient against evolving cyber risks.

The growing threat of cyberattacks in supply chains

Cybercriminals are exploiting vulnerabilities in supply chains to launch increasingly sophisticated attacks. Whether it’s targeting suppliers, compromising communication channels, or using phishing to manipulate employees, these threats are growing in scale and impact.

According to Gartner’s 2023 Supply Chain Risk Management Survey, supply chain attacks are becoming increasingly prevalent. The report highlights that 63% of surveyed organisations experienced a supply chain attack over the past year.

Email security: A critical vulnerability

Email remains the backbone of communication in supply chain operations. Unfortunately, it is also one of the weakest links in cybersecurity. Hackers commonly exploit email vulnerabilities through:

Social Engineering Attacks: Cybercriminals impersonate trusted entities, such as suppliers or executives, to trick victims into sharing sensitive information or transferring funds.
Phishing Campaigns: Attackers send fake emails designed to steal credentials or inject malware into systems.
Vendor Compromises: Fraudsters infiltrate suppliers’ systems to gain access to a company’s network, bypassing conventional defences.

The stakes are high. A single malicious email can lead to significant financial losses, operational disruptions and damage to customer trust.

Three common supply chain cyber threats

The three types of supply chain attacks seen most frequently can be segmented into:

The “fake” supply chain-Social engineering attacks are a persistent threat, with hackers impersonating stakeholders to manipulate employees into disclosing information or transferring funds. For instance, during the COVID-19 pandemic, scammers posed as logistics companies or suppliers of personal protective equipment to exploit urgent demands.

Supplier-managed resource attacks- Hackers often target suppliers’ IT systems or data stores to infiltrate larger networks. Data breaches, cloud misconfigurations and DNS hijacking are common methods used to exploit these vulnerabilities.

Supplier access to customer systems- Sophisticated attackers exploit supplier access to company systems, often through compromised software or hardware. High-profile incidents, such as the SolarWinds breach, illustrate the devastating potential of these attacks.

Email security best practices for supply chains

To effectively manage supply chain cyber risks, businesses should adopt a proactive approach to email security. Topsec recommends:

Implementing Advanced Email Authentication: Use protocols like DMARC, DKIM, and SPF to prevent domain spoofing and unauthorised email use.

Raising Awareness Through Training: Regularly train employees to recognise phishing emails, identify suspicious activity, and follow security best practices.

Monitoring and Responding to Threats: Employ managed email security services like to stay ahead of potential vulnerabilities and attacks.
