The state-level attack on the SSL CA security model
by Martin Millnert 09 Oct '25

09 Oct '25

To my surprise, I did not see a mention in this community of the latest proof of the complete failure of the SSL CA model to actually do what it is supposed to: provide security, rather than a false sense of security. Essentially a state somewhere between Iraq and Pakistan snatched valid certs for: - mail.google.com - www.google.com - login.yahoo.com - login.skype.com - addons.mozilla.org - login.live.com - "global trustee" https://blog.torproject.org/blog/detecting-certificate-authority-compromise… http://www.comodo.com/Comodo-Fraud-Incident-2011-03-23.html http://www.imperialviolet.org/2011/03/18/revocation.html (on epic failure of cert revocation lists implementations in browsers, failing open (!)) http://blog.mozilla.com/security/2011/03/22/firefox-blocking-fraudulent-cer… http://www.microsoft.com/technet/security/advisory/2524375.mspx For over a week users of browsers, and the internet at large, were/was not informed by COMODO that their security was compromised. "Why not" is beyond many of us. Announcing this high and loud even before fixes were available would not have exposed more users to threats, but less. Conclusion: protecting people must not be a priority in the SSL CA model. In some places, failure of internet security means people die, and it is high time to start serious work to replace this time-and-time again proven flawed model with something that, at the very least, does not fail this tragically. DNSSEC is a good but insufficient start in this particular case. Regards, Martin

Ransom DDoS attack - need help!
by halp us 18 Jul '25

18 Jul '25

All, I've been a NANOG member for many years but I'm emailing from an anonymous account to reduce the chance of the attackers finding me. A company that shall remain anonymous has received a ransom DDoS note from a very well known group that has been in the news lately. Recently they've threatened to carry out a major DDoS attack if they are not paid by a deadline which is approaching. They've performed an attack of a smaller magnitude to prove that they're serious. Based on certain details that I can't reveal here, we believe the magnitude of the upcoming attack may be in the several hundred Gbps. I would really appreciate help in a few areas (primarily with certain provider contacts/intros) so we can execute our strategy (which I can't reveal here for obvious reasons). If you email me off-list with a name/email that you've previously used on-list, I will reply from my real email. Alternatively, if you can post your experiences on-list with large scale high profile ransom DDoS attacks, I'd really appreciate it! Thanks

Open source Netflow analysis for monitoring AS-to-AS traffic
by Brian Knight 10 Jun '24

10 Jun '24

What's presently the most commonly used open source toolset for monitoring AS-to-AS traffic? I want to see with which ASes I am exchanging the most traffic across my transits and IX links. I want to look for opportunities to peer so I can better sell expansion of peering to upper management. Our routers are mostly $VENDOR_C_XR so Netflow support is key. In the past, I've used AS-Stats [1] for this purpose. However, it is particularly CPU and disk IO intensive. Also, it has not been actively maintained since 2017. InfluxDB wants to sell me [2] on Telegraf + InfluxDB + Chronograf + Kapacitor, but I can't find any clear guide on what hardware I would need for that, never mind how to set up the software. It does appear to have an open source option, however. pmacct seems to be good at gathering Netflow, but doesn't seem to analyze data. I don't see any concise howto guides for setting this up for my purpose, however. I'm aware Kentik does this very well, but I have no budget at the moment, my testing window is longer than the 30 day trial, and we are not prepared to share our Netflow data with a third party. Elastiflow [3] appears to have been open source [4] at one time in the past, but no longer. Since it too appears to be hosted, I have the same objections as I do with Kentik above. On-list and off-list replies are welcome. Thanks, -Brian Links: ------ [1] https://github.com/manuelkasper/AS-Stats [2] https://www.influxdata.com/what-are-netflow-and-sflow/ [3] https://www.elastiflow.com/ [4] https://github.com/robcowart/elastiflow?tab=readme-ov-file

TFTP over anycast
by Javier Gutierrez 07 Apr '24

07 Apr '24

Hi, I'm working on some DR design and we want to not only have this site as a DR but also performing some active/active for some of the services we hosts and I was wondering if someone had some experience with using anycast for TFTP or DHCP services? What are some of the pains/challenges you experienced and things we should lookout for? Any input is greatly appreciated. Kind regards, Javier Gutierrez

DNSSEC & WIldcards

So have *.app.linktechs.net that I have been trying to get to work, we have DNSSEC on this, and its failing, but cannot for the life of me understand why. I think it may have something to do with proving it exists as a wildcard, but any DNSSEC experts want to take a stab at it ? Dennis Burgess

SRI's Dan Lynch dies

>From Lauren Weinstein @ PRIVACY Digest: """ Dan Lynch, one of the key people involved in building the Internet and ARPANET before it, has died. Dan was director of computing facilities at SRI International, where ARPANET node #2 was located and he worked on development of TCP/IP, and where the first packets were received from our site at UCLA node #1 to SRI, and later at USC-ISI led the team that made the transition from the original ARPANET NCP protocols to TCP/IP for the Internet.

N91 Women mixer on Sunday?
by Ilissa Miller 02 Apr '24

02 Apr '24

For those that know me, I rarely provide constructive input about NANOG matters due to my past affiliation, however, I just saw that NANOG announced the Women mixer on Sunday before NANOG 91 and am outraged for all of the young professional women who would like to participate in NANOG. While the times are changing, women continue to remain primary caregivers for families and this will require them to desert their families a day early. I find it offensive personally and feel like you may have missed the mark. The amount of times I hear people complain about having to leave their families is one of the reasons this industry has a problem keeping young people - especially women. Does anyone else feel the same? -- *Ilissa Miller* *CEO, iMiller Public Relations <http://www.imillerpr.com>*
