ChatGPT on BGP Routing Security
I wanted to include a few examples of BGP bugs causing widespread disruption in the Network Security Fallacies presentation. I tried to find what happened when someone announced beacon prefixes with unknown optional transitive attributes (which should have been passed without complaints but weren’t) without knowing when it happened or who did it.
Trying to find the answer on Google proved to be a Mission Impossible – regardless of how I structured my query, I got tons of results that seemed relevant to a subset of the search words but nowhere near what I was looking for. Maybe I would get luckier with a tool that’s supposed to have ingested all the world’s knowledge and seems to (according to overexcited claims) understand what it’s talking about.
Hedge 172: Roundtable! SONiC, Open Source, and Complexity
It’s roundtable time at the Hedge! Eyvonne Sharp, Tom Ammon, and I start the conversation talking about the SONiC open source NOS, and then wander into using open source, build versus buy, and finally complexity in design and deployment.
Thanks for listening–if you have an idea for a Hedge episode, would like to be a guest, or know someone you think would be a good guest, let one us know!

Day Two Cloud 188: Out-Of-Band Management And Infrastructure Automation With ZPE Systems (Sponsored)
On today's Day Two Cloud podcast we talk through out-of-band management network design with sponsor ZPE Systems. If your idea of OOB management is a jump box and some terminal servers, there’s a lot more to the story when you bring automation tooling into the picture. We'll learn how ZPE gear works and talk with customer Vapor IO about using ZPE gear in its edge compute sites.

The use of artificial intelligence (AI), and especially GPU-powered AI, can help telcos solve some of their biggest challenges.Killnet and AnonymousSudan DDoS attack Australian university websites, and threaten more attacks — here’s what to do about it
Over the past 24 hours, Cloudflare has observed HTTP DDoS attacks targeting university websites in Australia. Universities were the first of several groups publicly targeted by the pro-Russian hacker group Killnet and their affiliate AnonymousSudan, as revealed in a recent Telegram post. The threat actors called for additional attacks against 8 universities, 10 airports, and 8 hospital websites in Australia beginning on Tuesday, March 28.
Killnet is a loosely formed group of individuals who collaborate via Telegram. Their Telegram channels provide a space for pro-Russian sympathizers to volunteer their expertise by participating in cyberattacks against western interests.
This is not the first time Cloudflare has reported on Killnet activity. On February 2, 2023 we noted in a blog that a pro-Russian hacktivist group — claiming to be part of Killnet — was targeting multiple healthcare organizations in the US. In October 2022, Killnet called to attack US airport websites, and attacked the US Treasury the following month.
As seen with past attacks from this group, these most recent attacks do not seem to be originating from a single botnet, and the attack methods and sources seem to vary, suggesting Continue reading
Studying EVPN to Prepare for a Job Interview
An ipSpace.net subscriber sent me this question:
I am on job hunting. I have secured an interview and they will probably ask me about VxLAN BGP EVPN fabrics. If you have some time, it would be a great help for me if you could tell me 1 or 2 questions that you would ask in such interviews.
TL&DR: He got the job. Congratulations!

Myth Busting: You Can’t Use Packet Monitoring for Enterprise Security
Security teams today realize the value of packet monitoring for cybersecurity. As they find more uses for packet monitoring, they shatter the myth that the latter is insufficient on its own.Cloudflare’s commitment to the 2023 Summit for Democracy
On Tuesday, March 28, 2023, the US Government will launch the Summit for Democracy 2023, following up on the inaugural Summit for Democracy 2021. The Summit is co-hosted by the United States, Costa Rica, Zambia, the Netherlands, and South Korea. Cloudflare is proud to participate in and contribute commitments to the Summit because we believe that everyone should have access to an Internet that is faster, more reliable, more private, and more secure. We work to ensure that the responsibility to respect human rights is embedded throughout our business functions. Cloudflare’s mission — to help build a better Internet — reflects a long-standing belief that we can help make the Internet better for everyone.
Our mission and core values dovetail with the Summit’s goals of strengthening democratic governance, respect for human rights and human rights defenders, and working in partnership to strengthen respect for these values. As we have written about before, access to the Internet allows activists and human rights defenders to expose abuses across the globe, allows collective causes to grow into global movements, and provides the foundation for large-scale organizing for political and social change in ways that have never been possible before.
