⚡️ Network Engineering Community News
Summer greetings from FastNetMon! While temperatures rise, so do DDoS attack volumes—and we’re here to help you stay cool under pressure. This month, we’re sharing two practical guides for tackling attacks, a press interview on SafetyDetectives, and major botnet updates, a peek at some of the biggest attacks we’ve seen recently and more.

🛡️ Practical guide to filtering L3/L4 DDoS attacks

UDP floods, TCP SYN storms, and other packet-level attacks can overwhelm even well-prepared networks. In this new guide, we explain how to use BGP Flow Spec and RTBH to filter malicious traffic efficiently – without impacting legitimate users.
💬 Interview: Rethinking DDoS defence with Safety Detectives

We recently sat down with Safety Detectives to talk through the realities of defending against today’s DDoS threats.
From why static rules are no longer enough to how we see automation reshaping mitigation, the interview covers both practical strategies and long-term thinking.
📚 FastNetMon library: Our DDoS talks, slides, and videos in one place

Missed one of our recent talks? Slow day in the office?
We’ve put together a growing library of our presentations – covering FastNetMon Community, Flow Spec for DDoS, Network Telemetry and more. Whether you want to catch up on a deep-dive technical session or share slides with your team, everything’s now in one place for easy access.
More content is coming soon, so it’s worth bookmarking.
🎯 Setting the thresholds for RTBH

In this guide, we walk through a practical method for setting RTBH thresholds that strike the right balance. It’s based on what we’ve seen work in production: quick to implement, easy to adjust, and designed to give you better control during live attacks.
If you’re running mitigation manually or fine-tuning an automated setup, this walkthrough will help you avoid guesswork and protect availability more effectively.
📰 Industry News Round-up
Here are some interesting industry takes and major DDoS incidents you should know about. Enjoy the reading!:
- 🕵️♂️ Europol Busts Major Botnet Crew: A coordinated takedown hits one of the most persistent pro-Russian DDoS crews, but their decentralised infrastructure remains a concern. Read all about Europol action here.
- 💀 Rise of RondoDox: This stealthy new botnet quietly builds firepower by targeting vulnerable routers and DVRs across global networks. We wrote about how it operates and vulnerabilities it exploits. RondoDox explained here.
- 💣 New DDoS botnet alert: HpingBot. This new botnet uses the open-source hping3 tool alongside Pastebin for command and control. How accessible has DDoS tooling become for anyone willing to put in minimal effort? Find out here.
- 🎮 Game On, DDoS Off: After a string of outages affecting gameplay, the developers have rolled out stronger filtering and control rules. The move appears to be holding off attacks – for now. Catch up on the full story here.
