As Distributed Denial of Service (DDoS) attacks continue to evolve, attackers are increasingly using techniques designed to evade conventional detection and mitigation mechanisms. One such technique is the carpet bombing DDoS attack, which distributes attack traffic across multiple IP addresses rather than concentrating it on a single target.
By spreading traffic across an entire subnet, carpet bombing attacks can create significant aggregate pressure while keeping the traffic directed at each individual IP address relatively low.
This approach can make detection and mitigation more challenging for organisations relying on per-IP thresholds, firewalls, load balancers, CDNs or cloud-based DDoS protection services.
What Is a Carpet Bombing DDoS Attack?
A carpet bombing DDoS attack distributes traffic across multiple IP addresses within a defined subnet, such as a /28, /24 or larger IP range.
Instead of sending the entire attack volume towards a single server or IP address, traffic is distributed across many destinations simultaneously.
Traditional DDoS Attack
One target → Concentrated attack traffic → Individual service or system becomes overwhelmed
Carpet Bombing DDoS Attack
Multiple targets → Distributed attack traffic → Aggregate infrastructure becomes overwhelmed
This distributed approach can make carpet bombing attacks more difficult to identify because no individual destination necessarily experiences the traffic spike normally associated with a large volumetric DDoS attack.
Why Are Carpet Bombing DDoS Attacks Difficult to Detect?
Many DDoS protection mechanisms rely on thresholds that monitor traffic directed towards individual IP addresses or services.
Carpet bombing attacks can challenge this approach by distributing traffic across many destinations while maintaining significant aggregate traffic volume.
Potential challenges include:
- No single IP address experiences an obvious traffic spike
- Aggregate traffic across the subnet can still be substantial
- Per-IP mitigation thresholds may not activate
- Individual traffic patterns may appear relatively normal
- Load balancers may be unable to compensate for distributed infrastructure pressure
- Firewalls and other network devices may become overwhelmed by aggregate traffic
- Upstream network capacity may become saturated before individual hosts reach their limits
As a result, an organisation may appear protected when individual IP addresses are evaluated separately while still remaining vulnerable to a distributed attack across the wider network range.
Why Organisations Should Test Against Carpet Bombing
Many DDoS resilience assessments focus primarily on attacks directed towards a single IP address or application.
While single-target testing remains important, it may not reveal weaknesses that only become visible when attack traffic is distributed across multiple destinations.
For example:
“Our primary IP address is protected.”
But how does the wider subnet behave when multiple IP addresses are targeted simultaneously?
“Our firewall can mitigate SYN floods.”
But can the infrastructure maintain availability when SYN flood traffic is distributed across dozens or hundreds of destinations?
“Our ISP provides DDoS mitigation.”
But will mitigation mechanisms detect lower-rate traffic distributed across an entire IP range?
Controlled carpet bombing testing can help answer these questions before a real attack occurs.
How LODDOS Supports Carpet Bombing DDoS Testing
LODDOS enables organisations to conduct controlled carpet bombing tests against authorised IP ranges.
Security teams can distribute defined amounts of attack traffic across selected IP blocks and observe how network infrastructure, mitigation technologies and services respond under distributed traffic conditions.
LODDOS Carpet Bombing Testing Capabilities
- Traffic Distribution Across Selected IP Ranges
- Configurable Bandwidth and Bot Capacity
- Multi-Attack Support with Up to Three Simultaneous Attack Vectors
- Layer 3, Layer 4 and Layer 7 Attack Scenarios
- Real-Time Monitoring
- Up to 4,000 Bots and Approximately 240 Gbps Testing Capacity
- AI-Powered Reporting and Mitigation Insights
These capabilities allow organisations to evaluate carpet bombing scenarios at different traffic levels and across different network ranges.
What Can Carpet Bombing Testing Help Identify?
Controlled testing can reveal weaknesses that may remain hidden during conventional single-target DDoS assessments.
Vulnerable Subnets
Testing multiple destinations can help identify parts of the network that respond differently under distributed attack conditions.
Firewall and TMS Limitations
Security teams can evaluate whether firewalls, Traffic Management Systems (TMS) and other mitigation controls continue to operate effectively when traffic is spread across multiple targets.
ISP and Upstream Mitigation Behaviour
Carpet bombing testing can help organisations understand how upstream providers detect and respond to distributed traffic patterns.
Scrubbing Centre Capacity
Organisations using scrubbing services can evaluate whether traffic diversion and filtering mechanisms behave as expected during distributed attacks.
Network Saturation Points
Testing can reveal aggregate bandwidth or infrastructure bottlenecks that may not become visible when only a single destination is targeted.
Operational Preparedness
Security Operations Centre (SOC), network and infrastructure teams can use controlled testing to practise detection, escalation and mitigation procedures for distributed DDoS scenarios.
Test Carpet Bombing Attacks Before They Become a Real Incident
Carpet bombing DDoS attacks demonstrate why evaluating only individual IP addresses may not provide a complete picture of DDoS resilience.
By distributing traffic across multiple destinations, attackers can place significant pressure on network infrastructure while potentially remaining below mitigation thresholds configured for individual systems.
LODDOS enables organisations to reproduce these distributed attack patterns in a controlled and authorised testing environment, helping security teams identify hidden weaknesses, validate mitigation mechanisms and improve their overall DDoS resilience.
Test your infrastructure against controlled carpet bombing DDoS scenarios and identify weaknesses before attackers do.
