Quickscan routing security
by Ad Bresser 03 Mar '18

03 Mar '18

Dear routing-wg, Last year I composed a quickscan on routing measures to increase the security of the Internet. You can download it at: http://startupinc.nl/wp-content/uploads/2017/10/20171027-Quickscan-on-routi… In order to improve the overview I also created a Github version. Please add your additions here: https://github.com/AdBresser/measures-to-increase-IP-security Hope this helps in improving the IP security of the Internet. Kind regards, Ad Bresser PS For sharing in your LinkedIN network a version of the quickscan is available on LinkedIN: https://www.linkedin.com/pulse/measures-increase-routing-security-internet-… (likes are also appreciated 😉 )

Update: New Active Exploit: memcached on port 11211 UDP & TCP being exploited for reflection attacks
by Barry Greene 01 Mar '18

01 Mar '18

[The posting is sent to APOPS, AfNOG, SANOG, PacNOG, SAFNOG, CaribNOG, TZNOG, MENOG, SDNOG, LACNOG, IRNOG, MYNOG, SGOPS, and the RIPE Routing WG.] UPDATE: As of 2018-02-28, more attacks using the memcached reflection vector have been unleashed on the Internet. Operators are asked to port filter (Exploitable Port Filters), rate limits the port 11211 UDP traffic (ingress and egress), and clean up any memcached exposed to the Internet (iptables on UNIX works). These mitigations should be on IPv4 and IPv6! There is not excuse for ISPs, Telcos, and other operators for not acting. NTT is an example of action. As stated by Job Snijders <job(a)ntt.net <mailto:job@ntt.net>> on the NANOG List: “NTT too has deployed rate limiters on all external facing interfaces on the GIN backbone – for UDP/11211 traffic – to dampen the negative impact of open memcached instances on peers and customers. The toxic combination of ‘one spoofed packet can yield multiple reponse packets’ and ‘one small packet can yield a very big response’ makes the memcached UDP protocol a fine example of double trouble with potential for severe operational impact.” This post has been updated with recommendations. Check with your network vendors for deployment/configuration details. http://www.senki.org/memcached-on-port-11211-udp-tcp-being-exploited/ <http://www.senki.org/memcached-on-port-11211-udp-tcp-being-exploited/> ----------------
