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

Incorrect Reverse DNS in Verizon Fios NYC core router traceroute
by Neel Chauhan 18 Nov '24

18 Nov '24

Hi, I got Fios installed today in my NYC apartment, as I just moved back from Seattle after a 4-month stay in Connecticut. When doing a traceroute, I am noticing an incorrect Reverse DNS entry: [root@twin ~]# traceroute 1.1.1.1 traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 60 byte packets 1 _gateway (172.20.0.1) 0.145 ms 0.115 ms 0.106 ms 2 lo0-100.NYCMNY-VFTTP-372.verizon-gni.net (173.56.84.1) 2.079 ms 2.070 ms 2.061 ms 3 G0-3-4-4.PITBPA-LCR-21.verizon-gni.net (100.41.196.252) 3.751 ms T0-8-0-9.BSTNMA-LCR-21.verizon-gni.net (100.41.196.248) 4.454 ms 4.447 ms 4 * * * 5 * * * 6 162.158.61.113 (162.158.61.113) 7.246 ms 6.603 ms 162.158.61.117 (162.158.61.117) 4.944 ms 7 one.one.one.one (1.1.1.1) 6.077 ms 6.355 ms 6.346 ms [root@twin ~]# In short, hop 3 is "G0-3-4-4.PITBPA-LCR-21.verizon-gni.net (100.41.196.252)" which seems to be a Pittsburgh, PA reverse DNS entry even when I'm in NYC. While it doesn't affect the normal operation of the service, it might give the impression packets are being routed via Pittsburgh to someone less savvy. If someone works at the Verizon Fios/ILEC network engineering or sysadmin team could the 100.41.196.252 reverse DNS entry to say "G0-3-4-4.NYCMNY-LCR-21.verizon-gni.net" please get updated? Thanks!

WSJ: China-Linked Hackers Breach U.S. ISPs in New "Salt Typhoon" attack
by Sean Donelan 05 Oct '24

05 Oct '24

Wall Street Journal out with an 'exclusive' article. This is apparently different than the other *-Typhoon groups (or whatever your favorite threat intelligence provider calls then). I don't know why the *-Typhoon groups would limit their intrusions to only U.S. ISPs. Broadband ISPs in other countries may have similar issues. China-Linked Hackers Breach U.S. Internet Providers in New ‘Salt Typhoon’ Cyberattack https://www.wsj.com/politics/national-security/china-cyberattack-internet-p… Hackers linked to the Chinese government have broken into a handful of U.S. internet-service providers in recent months in pursuit of sensitive information, according to people familiar with the matter. The hacking campaign, called Salt Typhoon by investigators, hasn’t previously been publicly disclosed and is the latest in a series of incursions that U.S. investigators have linked to China in recent years. The intrusion is a sign of the stealthy success Beijing’s massive digital army of cyberspies has had breaking into valuable computer networks in the U.S. and around the globe. In Salt Typhoon, the actors linked to China burrowed into America’s broadband networks. In this type of intrusion, bad actors aim to establish a foothold within the infrastructure of cable and broadband providers that would allow them to access data stored by telecommunications companies or launch a damaging cyberattack.

is it common to proxy register route objects for the purpose of grouping them for use in an as-set
by Steven Wallace 27 Sep '24

27 Sep '24

Greeting, One of the DDoS mitigation providers we work with creates proxy route objects for its customers’ prefixes. These route objects specify a common origin ASN rather than the actual origin ASN that would be seen in routing tables. Their rationale is to bind the prefixes to a single ASN, allowing the entire set of customer routes to be announced via an as-set. Is this a common approach? Just curious. thanks, steve Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu
