DDos Attacks
Episode Summary
In this episode of Ehsan’s Tech Lounge, we discuss modern DDoS attacks.
Your home modem may be online right now and, without your knowledge, could already be part of a massive cyber army.
The new generation of DDoS attacks no longer targets only a single server or a specific IP address. In Carpet Bombing attacks, malicious traffic is distributed across hundreds of IP addresses within the same prefix. This allows the attack to remain below the detection thresholds of traditional defense systems while ultimately overwhelming the router and all the services behind it.
On the other hand, Flash Attacks, also known as Pulse Attacks, are launched in extremely fast and short bursts. In some cases, the attack may already be over before traditional DDoS protection systems can detect it and respond.
In this video, we explore:
- How does Carpet Bombing work?
- Why are short and sudden attacks so difficult to detect?
- How do infected home modems become part of a botnet?
- How can outbound DDoS attacks cripple an ISP from inside its own network?
- Why are traditional defenses and volume-based thresholds no longer sufficient?
- What roles do FlowSpec and RTBH play in mitigating these attacks?
- How has artificial intelligence made cyberattacks faster and more intelligent?
When we talk about attacks reaching 14 or 31 terabits per second, the issue is no longer limited to a single website becoming unavailable. Traffic at this scale can affect routers, network links, and a significant portion of an Internet service provider’s infrastructure.
What do you think ISPs should do to identify infected modems and stop DDoS attacks as close to the source as possible?

Key Takeaways
- Understand how Carpet Bombing distributes malicious traffic across many IP addresses within the same prefix.
- Learn why short Flash or Pulse attacks can be difficult for traditional DDoS defenses to detect in time.
- Understand how infected home modems can become part of botnets and generate outbound DDoS traffic.
- Review the roles of BGP FlowSpec and RTBH in DDoS mitigation.
- Understand why very large attacks can affect routers, links, and broader ISP infrastructure.

Detailed Notes
The episode focuses on modern DDoS behavior rather than attacks against only one server or IP address.
It explains how distributed attack traffic can remain below individual detection thresholds while still overwhelming shared infrastructure.
It also discusses why extremely short attack bursts create detection and response challenges.
The episode closes by considering how ISPs can identify infected modems and stop malicious traffic closer to the source.
