Just one weakness anywhere in your network, or among your suppliers, can expose your entire business, says Steve Knibbs, Director of Vodafone Business Security Enhanced (VBSE), as he takes stock of cyberattacks on business supply chains - and how to protect against them.
Cyber-criminals are no longer targeting individual companies – they’re attacking entire ecosystems. The recent cyber-attack against one of the UK’s largest car manufacturers didn’t just halt production; it paralysed hundreds of suppliers, disrupted deliveries nationwide, and caused millions in lost revenue – with some estimates suggesting losses of up to £50 million per week. Sadly, this level of large-scale disruption is unlikely to be the last.
As we acknowledge Cybersecurity Awareness Month, recent findings from the Chartered Institute of Procurement & Supply (CIPS) reveal that almost one-in-three UK business leaders have noticed an increase in cyber-attacks on their supply chains within the last six months. This isn’t a minor fluctuation; it represents a significant escalation.
If your partners are vulnerable, that vulnerability extends to your own business as well.
The cybersecurity threats facing every small business
For every online threat, there’s a shield to protect your business and your customers – here's everything you need to know, including how Vodafone Business can help.
Cyberattacks on supply chains: The domino effect of a single breach
The recent cyber-attack on the UK car manufacturing industry has laid bare just how vulnerable and interdependent today’s supply chains are. When a major player falls victim, it’s not just their operations that suffer – hundreds of smaller suppliers can be brought to a standstill. Payments dry up, cashflow is disrupted, and orders can disappear overnight.
These cyber incidents do far more than harm a single business. The repercussions ripple outwards, impacting every supplier, partner, and system that’s connected. For smaller and medium-sized firms, losing access to systems for even a short time can spell disaster, putting their very survival at risk.
This is no longer a hypothetical concern. It’s a reality that’s already unfolding – and it’s the most vulnerable businesses that are bearing the brunt.

Cyberattacks on supply chains: Why urgency matters
Every out-of-date system, unsecured supplier or neglected endpoint is an open invitation to cyber-criminals. With automation and AI, attackers can exploit these weaknesses at unprecedented speed and scale. Just one weakness anywhere in your network, or among your suppliers, can expose your entire business.
Despite this, many UK companies still approach supply chain cyber security as little more than a box-ticking exercise. The truth is stark: your organisation’s security is only as strong as the weakest link in your supply chain.
Earlier this year, our research found that small and medium-sized enterprises (SMEs) throughout the United Kingdom were incurring annual losses amounting to £3.4 billion due to having inadequate cyber security measures.
We are now at a crossroads where failing to act isn’t just risky – it borders on negligence.

Cyberattacks on supply chains: What every business must do now
To protect against vulnerabilities across the supply chain, businesses should take immediate, practical steps:
- Map your supply chain: Understand who has access to your systems, networks and data. Mapping this helps identify shadow suppliers and inherited risks before they become problems.
- Adopt a Zero Trust approach: Ensure all access is verified, monitored and limited. Zero Trust enables real-time threat detection, unified security and greater control over how systems interact.
- Use best practice frameworks: Organisations like the government’s National Cyber Security Centre (NCSC) offer comprehensive cyber security guidance for organisations of all sizes.
- Embed clear access and authentication controls: Set baseline expectations with every new supplier from day one – not after issues arise. Define roles, credentials, multi-factor authentication and audit processes at the start.
- Develop and test a cyber incident response plan: Effective response processes in the event of an attack can help reduce downtime and protect business continuity. The NCSC also offers useful advice about how to manage any incidents.
- Foster resilient partnerships: Build relationships with partners who provide full visibility across the supply chain and can help you detect, respond to, and recover from threats quickly and collaboratively.

AI-enhanced scams: how to protect yourself
Cybercriminals who use AI to defraud people sound intimidating and impossible to defend against, but protecting yourself is straightforward according to cybersecurity expert Dr Katie Paxton-Fear.
Through our partnership with CybSafe, we also enhance human risk management, empowering employees to recognise and respond to threats effectively. Combined with continuous monitoring, rapid patching, and robust recovery plans, this ensures operational continuity and stakeholder confidence.
Cyberattacks on supply chains: Act now as proactive security is critical
Recent incidents – including findings from the latest CIPS report and multiple breaches across the retail sector – reveal a stark reality: UK digital supply chains are facing relentless, increasingly sophisticated cyber threats.
Waiting for the next attack is not an option. Organisations must act now – patching vulnerabilities, strengthening defences, monitoring systems in real time, and preparing comprehensive contingency plans. The threat landscape is evolving too rapidly for hesitation.
Cyber resilience has become a leadership imperative. It extends far beyond IT, underpinning brand reputation, customer trust, and business continuity.
A single breach can disrupt entire supply chains, impacting every partner and stakeholder connected to your organisation. Now is the time to build resilience, protect your ecosystem, and secure your business for the future.
