What are Supply Chain Attacks?

Supply chain attacks are a major cyber threat facing organisations. These attacks can cause far-reaching and costly disruption, as they exploit vulnerabilities in a supplier's systems to gain access to a customer's network of contacts. 

In recent years, there has been a significant increase in cyber attacks resulting from vulnerabilities within supply chains. This includes many high-profile incidents such as the SolarWinds attack or the 2023 3CX Desktop Software Attack, which were both caused by attacks that originated outside of their organisations.

What happened in the SolarWinds attack?

Over recent years, cyber attacks exploiting vulnerabilities within supply chains have escalated, causing widespread and costly disruptions. The high-profile SolarWinds attack serves as a stark reminder of the potential consequences.

The attack, which was discovered in late 2020, was a large-scale cyber espionage campaign that impacted numerous government agencies, businesses, and other organisations worldwide. Hackers infiltrated the IT infrastructure of organisations by compromising the software update mechanism of SolarWinds Orion, a widely used network management software. The compromised update served as a Trojan horse that gave the attackers backdoor access to networks, allowing them to steal sensitive data. The sophisticated nature of the attack and its extensive reach across various sectors raised serious concerns about global cybersecurity infrastructure and strategies.

What about the Draytek firewall attack?

You can view our recent client advisory documentation in which we informed clients about the widespread failures experienced by DrayTek firewall users on March 22nd, 2025. The document touches on the loss of internet connectivity, devices stuck in reboot loops and corrupted firewall settings. The document also highlights ongoing security vulnerabilities (CVEs) affecting DrayTek firewalls and the next steps for our clients and affected customers.

What is the current guidance from the National Cyber Security Centre?

Astonishingly, only just over one in ten businesses (13%) review the risks posed by their immediate suppliers, and the figure drops to a mere 7% for the wider supply chain. 

The National Cyber Security Centre (NCSC) has recently published new guidance to help organisations effectively assess and gain confidence in the cyber security of their supply chains. 

The National Cyber Security Centre reiterated that it is crucial for organisations to collaborate with their suppliers and establish robust security measures to safeguard against cyber security threats. The NCSC's guidance is specifically designed to help organisations effectively evaluate the cyber risks associated with their suppliers and gain confidence in existing mitigation measures. 

Ian McCormack, NCSC Deputy Director for Government Cyber Resilience, said: 

“Supply chain attacks are a major cyber threat facing organisations and incidents can have a profound, long-lasting impact on businesses and customers.
 
“With incidents on the rise, it is vital organisations work with their suppliers to identify supply chain risks and ensure appropriate security measures are in place." 

The guidance describes typical supplier relationships and potential weaknesses that might expose their supply chain to attacks. It also defines the expected outcomes and identifies key steps to help organisations assess their supply chain's security.
