Mantis – the most powerful botnet to date
In June 2022, we reported on the largest HTTPS DDoS attack that we’ve ever mitigated — a 26 million request per second attack - the largest attack on record. Our systems automatically detected and mitigated this attack and many more. Since then, we have been tracking this botnet, which we’ve called “Mantis”, and the attacks it has launched against almost a thousand Cloudflare customers.
Cloudflare WAF/CDN customers are protected against HTTP DDoS attacks including Mantis attacks. Please refer to the bottom of this blog for additional guidance on how to best protect your Internet properties against DDoS attacks.
Have you met Mantis?
We named the botnet that launched the 26M rps (requests per second) DDoS attack "Mantis" as it is also like the Mantis shrimp, small but very powerful. Mantis shrimps, also known as “thumb-splitters”, are very small; less than 10 cm in length, but their claws are so powerful that they can generate a shock wave with a force of 1,500 Newtons at speeds of 83 km/h from a standing start. Similarly, the Mantis botnet operates a small fleet of approximately 5,000 bots, but with them can generate a massive force — responsible for the largest Continue reading

Hedge 138: The Robustness Principle
Most network engineers take it as a “given” that the robustness principle is the “right way” to build protocols and networks—”be conservative in what you send, and liberal in what you receive.” The idea behind the robustness principle is that implementations should implement specifications as accurately as possible, but they should also accept malformed and otherwise erroneous data, process the best they can, and drop the bits they cannot process. This should allow the network to operate correctly in the face of defects and other failures. A recent draft, draft-iab-protocol-maintenance/, challenges the assumptions behind the robustness principle. Join Tom and Russ as they discuss the robustness principle and its potential problems.
