Key Trends & Landscape
- According to a recent report by SOCRadar, the UK recorded more than 111,000 DDoS attacks in recent periods, with peaks reaching 545 Gbps in bandwidth in some cases. (SoCyber)
- A report from NETSCOUT indicates that in the EMEA (Europe, Middle East, Africa) region, DDoS attacks grew by about 31% year-on-year in the first half of 2023, with the UK being a significant target. (UK Tech News)
- In the UK public sector, DDoS is flagged as the second biggest cyber threat for local councils (after phishing) in one study. (UK Tech News)
- The national cyber-security agency National Cyber Security Centre (NCSC) warned that hostile activity in cyberspace is increasing in frequency, sophistication and intensity — with 430 incidents in 2024, up from 371 in 2023. (Reuters)
Case Studies
Case Study 1: Public Sector – UK councils & DDoS
- A FOI request found that among 161 UK local authorities, they faced over 2.3 million cyber-attacks in the year to August 2022. In this set, DDoS attacks were the second largest threat after phishing. (UK Tech News)
- Commentary: Threat intelligence lead Richard Hummel of NETSCOUT said:
“DDoS attacks targeting the public sector and critical national infrastructure (CNI) are an ongoing problem … essential services … at particular risk.” (UK Tech News)
Case Study 2: Commercial / Technology Sector – Large‐scale DDoS in June 2025
- According to an article on SecurityBrief UK, the company Fastly logged a coordinated DDoS incident in June 2025 in which a major high-technology provider was hit with over 250 billion requests across two days — peaking at 1.6 million requests per second. (SecurityBrief UK)
- The attack originated from multiple countries (Germany, China, India, Netherlands, US) illustrating the global nature of DDoS campaigns. (SecurityBrief UK)
Case Study 3: State-linked / Geopolitical DDoS Activity
- In a press release summary from NETSCOUT, it’s noted that in 2024 the UK saw a 152% increase in DDoS activity on the day the national Parliament (the Parliament of the United Kingdom) resumed session, demonstrating how attacks are being timed for political effect. (Silicon UK)
- A specific example: the pro-Russian hacking group NoName057(16) claimed a campaign in May 2025 of DDoS attacks on UK websites (local councils, policing bodies) citing the UK’s involvement in the Ukraine conflict. (The Guardian)
Expert Comments & Observations
- From the NCSC, cyber security officials warn:
“Hostile activity in UK cyberspace has increased in frequency, sophistication and intensity … actors are increasingly using our technology dependence against us, seeking to cause maximum disruption and destruction.” (Reuters)
- On DDoS as a tactic: Richard Hummel (NETSCOUT) stated:
“DDoS has emerged as the go-to tool for cyberwarfare … NoName057(16) continues to be the leading actor for politically-motivated DDoS campaigns targeting governments …” (Silicon UK)
- On the business side: A UK tech-news article cites the view that the real number of attacks is far higher:
“Attacks are rising and getting more and more sophisticated. Those reported are just the tip of the iceberg.” — Roy Shelton, CEO Connectus Group. (UK Tech News)
Why DDoS is a Major Concern for the UK
- Service disruption: DDoS floods cause websites and services (especially public-facing ones) to go offline, which erodes public trust and can result in heavy economic/operational costs.
- Diversion & smokescreen: DDoS attacks are increasingly used in conjunction with other malicious activities (malware deployment, infiltration) — the DDoS draws attention while other malicious work happens in the background. (UK Tech News)
- Critical infrastructure risk: Because the UK economy and society depend heavily on interconnected digital services, DDoS attacks on energy, telecoms, government services can have outsized impact.
- Geopolitical dimension: DDoS is now a tool in state-or state-affiliated cyber campaigns, especially given the UK’s visibility on the world stage and its alliance structures (e.g., involvement in Ukraine).
- Complexity & scale growing: Attacks are larger (hundreds of billions of requests), more distributed, using AI/automation/botnets, harder to detect and mitigate.
What Organisations are Advised to Do
- Deploy adaptive DDoS defences at network edges: place mitigation closer to the “front-line” of your traffic flow rather than only at central firewalls. (UK Tech News)
- Regularly test your infrastructure (simulate attacks, monitor performance): as one article put it — “any adjustments made to applications or servers must be incorporated into the wider DDoS mitigation system.” (UK Tech News)
- Ensure robust vulnerability management: many attacks exploit known vulnerabilities; for example IBM found 50% of UK incidents in 2022 involved exploitation of vulnerabilities. (IBM UK Newsroom)
- Recognise that DDoS may be a diversion: organisations must monitor for signs of deeper infiltration even while mitigating DDoS. (UK Tech News)
- Increase awareness & reporting: Many attacks go unreported or only partially disclosed; businesses should build incident detection and reporting capacity. (UK Tech News)
- Here are several prominent case studies and commentary excerpts from UK tech-news sites illustrating how cyber-threats — especially DDoS-style attacks — are affecting UK organisations.
Case Studies
Case Study 1: State-linked DDoS campaign on UK public bodies
- A pro-Russian hacking group calling itself NoName057(16) claimed responsibility for a 3-day series of DDoS attacks on UK websites (including local councils and policing bodies) in May 2025. (The Guardian)
- The group’s stated motive: “Britain is invested in the escalation of the [Ukraine] conflict, and we are disconnecting its resources.” (The Guardian)
- While claims of full success were overstated, several councils reported temporary disruptions; the incident highlights how politically-motivated DDoS campaigns target UK public infrastructure. (The Guardian)
Case Study 2: DDoS used as a “smokescreen” for broader breaches
- According to a report covered by a UK tech-news site, in January 2023 DDoS attacks used concurrently with infiltration were rising: UK saw a ~17 % year-on-year increase in DDoS attacks used as diversion tactics. (UK Tech News)
- Industries especially affected: fintech (+71 %), retail (+51 %), gaming (+47 %) compared with same period previous year. (UK Tech News)
- Insight: The DDoS attack may not only cause disruption but also enable deeper malicious activity (data theft, malware) by diverting defenders’ attention. (UK Tech News)
Case Study 3: Cost and economic impact of DDoS on UK businesses
- A report cited by TechRadar estimated that DDoS attacks could cost the UK economy more than £1 billion per year. (TechRadar)
- The same article indicated that for UK businesses experiencing downtime from DDoS, the average cost exceeded £140,000, with downtime averaging ~67 minutes. (TechRadar)
- This illustrates that DDoS is not just an IT nuisance — it carries material economic risk for UK organisations.
Case Study 4: Surge in sophistication of DDoS attacks in UK & Ireland
- According to the NETSCOUT report (referenced in UK tech-news): In 1H2022, although the frequency in UK&I may have slightly dropped, the sophistication increased, with powerful botnets launching TCP-based “direct path” DDoS attacks. (UK Tech News)
- The timing of many attacks aligns with major global events (political, sports), indicating threat actors are leveraging media focus and infrastructure loads. (UK Tech News)
Expert Comments & Insights
- Roy Shelton, CEO of the Connectus Group, warned:
“Attacks are rising and getting more and more sophisticated. Those reported are just the tip of the iceberg. A lot more happen and exist under the radar and are never reported.” (UK Tech News)
This comment underscores that the visible incidents may only represent a fraction of the total threat environment. - From the TechRadar article:
It emphasised that “91 % of businesses surveyed by NETSCOUT said they had experienced network downtime as a direct result of a DDoS attack,” and that the average cost per minute of downtime for those affected UK businesses was £2,140. (TechRadar)
This brings out how DDoS attacks translate into measurable business risk. - On motive and actor profiles: In older UK-tech news coverage a survey by Kaspersky Lab found that nearly half (48%) of companies recently hit by DDoS believed they knew the perpetrator — and in about 12% of cases suspected a competitor paid for the attack. (Silicon UK)
This suggests that DDoS is not only a tool of state or criminal actors—but also corporate sabotage.
Summary of Key Take-Aways
- DDoS attacks in the UK are rising in both number and complexity, not just simple floods but multi-vector, combined with infiltration or data theft.
- The impact is significant — downtime, reputational risk, financial cost — for both public and private sectors.
- Public-sector infrastructure (councils, policing bodies) is being targeted in politically driven campaigns (e.g., NoName057(16) case).
- Business sectors (fintech, retail, gaming) are facing DDoS used as cover for deeper breaches.
- Many organisations still lack full visibility or adequate defensive readiness, meaning many incidents likely go undetected or unreported.
- The economic cost to the UK is substantial; investment in defence is rising, though the threat continues to evolve.
