The Growing Threat of DDoS Attacks And How to Defend Against Them
ADistributed Denial of Service (DDoS) attackis a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of traffic from multiple sources. Unlike a basic Denial of Service (DoS) attack, which comes from a single source, DDoS attacks leveragebotnets— networks of compromised devices — to amplify their impact and make them harder to stop.
What is DDoS?
ADistributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of traffic from multiple sources. Unlike a basic Denial of Service (DoS) attack, which comes from a single source, DDoS attacks leveragebotnets— networks of compromised devices — to amplify their impact and make them harder to stop.
The aim? Make your online service slow, unstable, or completely inaccessible to real users.
What’s the Impact?
The consequences of a DDoS attack can be severe:
- Revenue loss — Downtime directly translates to lost sales and missed opportunities.
- Reputation damage — Customers may lose trust in your ability to stay operational.
- Operational disruption — Internal systems and workflows grind to a halt.
- Increased vulnerability — Attackers may use the distraction to launch secondary attacks.
Even a short outage can have a lasting financial and reputational impact.
Common Targets
While any organization with an internet-facing presence is vulnerable, these industries are frequent targets:
- E-commerce
- Banking & Finance
- Online Gaming
- Healthcare
- Government Services
- SaaS providers
If your operations depend on consistent uptime, you’re at risk.
Kinds of DDoS Attacks
Volumetric Attacks– Saturate network bandwidth with huge volumes of traffic (e.g., UDP floods, ICMP floods).
Protocol Attacks– Exploit weaknesses in network protocols to exhaust server resources (e.g., SYN floods, Ping of Death).
Application Layer Attacks– Target specific applications to exhaust resources (e.g., HTTP floods).
Multi-Vector Attacks– Combine multiple attack strategies for maximum impact.
Develop a DDoS Attack Response Plan
To minimize damage, you need a clear action plan:
- Identify critical assets — Prioritize what needs protection the most.
- Implement traffic monitoring — Detect anomalies before they escalate.
- Assign roles & escalation paths — Ensure the right people act fast.
- Partner with a mitigation provider — Have resources ready to absorb attacks.
- Test with drills — Practice your plan under realistic conditions.

Britain's exposed controllers: a UK exposure report after the French fridge attack
After Sunday's cyberattack on French supermarket refrigeration, we turned the same question on the UK. Over 800 internet-exposed refrigeration and building-management controllers answer directly to the open internet here, across Danfoss, Carel, Copeland and other vendors, and that figure is a floor rather than a ceiling. Here is what we found, why France was hit and not Britain, and what to do this week.
Cyberattack defrosts the fridges at hundreds of French supermarkets
Overnight on 11–12 October 2026, attackers reached into the refrigeration controllers of several hundred French supermarkets and switched the fridges and freezers into a defrost cycle that never ended. Intermarché, Coopérative U, Carrefour and Leclerc lost their chilled and frozen stock, the Paris prosecutor has opened an investigation, and the equipment at the centre of it is sitting on the open internet in the UK too.
