A plea to ignore abuse reports from "watchdogcyberdefense.com"
by Pierre Bourdon 07 Nov '24

07 Nov '24

Hi nanog, Some of you might have seen https://delroth.net/posts/spoofed-mass-scan-abuse/ circulating last week (it was also sent here in reply to someone who received abuse complaints from their ISP). The TL;DR is that some previously unknown company with a fancy looking domain name has started noticing the background noise on the internet and is sending automated abuse complaints to any owner of a source IP sending a SYN packet to port 22 on their network. They're not doing any filtering to try to prevent spoofed source addresses, and at this point there's plenty of evidence that they are seeing mostly spoofed src IPs, then sending abuse reports to a completely uninvolved owner of the IP. I've recently been in communication with that company. They sent me an email trying to get "advice" from me about how to not send abuse complaints to the whole internet, while ignoring the obvious answer of "don't mass send automated abuse complaints based on no evidence of abuse and no evidence of who sent you traffic". They're also making wild claims in their email to me, like, I quote, seeing "1.3 billion attacks logged in the past 24 hours". They're saying that they act on data sources like "we query the VirusTotal API for the source IP and it shows us it's infected with malware". If you're a NOC or someone handling abuse complaints for an ISP or a hosting provider, this is my plea to you: please send abuse reports from "watchdogcyberdefense.com" to your spam box until they understand 1. that a TCP SYN packet is spoofable; 2. that they're harming the internet through reducing trust in abuse complaints by sending so many false positives. I've myself had interactions with both Hetzner and Linode's abuse team, both of them have been top notch and understood what they're likely dealing with, but having to explain to every single ISP what's going on while sitting in the equivalent of an interrogation room threatened with a service suspension isn't a very comfortable situation. Thank you in advance, Best, -- Pierre Bourdon <delroth(a)gmail.com> Software Engineer @ Zürich, Switzerland https://delroth.net/

Upcoming changes to the DNSSEC root trust anchor
by Andres Pavez 05 Nov '24

05 Nov '24

Dear Colleagues, We are reaching out to inform you of important changes to the DNSSEC trust anchor in the root zone. If you manage a validating DNS resolver or a tool that interacts with the DNS root zone you might need to change your software to handle the changes. This letter provides a summary of the upcoming changes and gives pointers to resources that describe them in detail. *Upcoming addition of the KSK-2024 trust anchor* On January 11, 2025, a new trust anchor, codenamed KSK-2024, will appear in the root zone for the global DNS. This key was generated earlier this year and will co-exist with the current trust anchor, codenamed KSK-2017. The new DNSKEY record is: . 172800 IN DNSKEY 257 3 8 AwEAAa96jeuknZlaeSrvyAJj6ZHv28hhOKkx3rLGXVaC6rXTsDc449/c idltpkyGwCJNnOAlFNKF2jBosZBU5eeHspaQWOmOElZsjICMQMC3aeHb GiShvZsx4wMYSjH8e7Vrhbu6irwCzVBApESjbUdpWWmEnhathWu1jo+s iFUiRAAxm9qyJNg/wOZqqzL/dL/q8PkcRU5oUKEpUge71M3ej2/7CPqp dVwuMoTvoB+ZOT4YeGyxMvHmbrxlFzGOHOijtzN+u1TQNatX2XBuzZNQ 1K+s2CXkPIZo7s6JgZyvaBevYtxPvYLw4z9mR7K2vaF18UYH9Z9GNUUe ayffKC73PYc= As a result of this addition, some DNS responses may be larger during the transition period. If your software uses the RFC 5011 process for managing trust anchors, KSK-2024 will be automatically trusted about one month after its introduction to the root zone. There are two important planned dates: * October 11, 2026: KSK-2024 will begin signing the root zone. * January 11, 2027: KSK-2017 is scheduled to be revoked. For a detailed description of the rollover process, please refer to https://www.iana.org/dnssec/files *New trust anchor file* IANA has issued a new trust anchor file using the updated XML format described in https://datatracker.ietf.org/doc/draft-ietf-dnsop-rfc7958bis/ , which has recently been approved to be published as an RFC. The new trust anchor file contains additional data that was not provided in previous versions of the file. If your software or processes use the IANA trust anchor file (published at https://data.iana.org/root-anchors/root-anchors.xml ), you should ensure you have processes to retrieve it regularly (such as weekly) and check your systems can process the revised format of the file. *Keep in touch* Operational announcements regarding trust anchors and rollovers are published on the root-dnssec-announce mailing list at https://lists.icann.org/postorius/lists/root-dnssec-announce.icann.org/ . A separate ksk-rollover mailing list is a forum for discussion specific to rollovers can be found at https://lists.icann.org/postorius/lists/ksk-rollover.icann.org/ . Best regards, -- Andres Pavez Cryptographic Key Manager

J Root woes on v4
by Eric Dugas 04 Nov '24

04 Nov '24

Hello, It seems that J Root has suboptimal routing over v4 but v6 is OK from my POV in Montreal, Canada. Route changes occurred ~5h ago. v4: ~260ms somewhere in Asia via our HE bilateral in Montreal, Canada (AS-PATH 6939 45629 55423 55423 26415 396651 396651) 55423 might host a legit J Root node, but it should be exported outside their region by AS45629 or HE. v6: ~24ms in Chicago via Arelion IPT in Montreal, Canada (AS-PATH 1299 7342 36631 36631) This one looks legit.

Microsoft NOC Contact - ASN Association Request
by Christopher Hawker 04 Nov '24

04 Nov '24

Hello all, If anyone from AS8075 is lurking around, could you please reach out to me off-list? Backstory: We submitted an ASN Association (not peering) request to associate our AS with an Azure tenancy, and they rejected the request on the grounds that they "currently don't see any traffic for ASN".

SSH bruteforce attempts from Verizon to "AS17452 Bitstop Inc"
by Neel Chauhan 31 Oct '24

31 Oct '24

Hi, I am a customer of Verizon Fios in NYC and received a very interesting abuse complaint today from abuse(a)verizon.com. I got SSH bruteforce attempts between my IP address and this IPv4 prefix: 202.91.160.0/20 This is hosted on a network called "AS17452 Bitstop Inc". My connection runs Tor relays, but not exit relays. I doubt it's Tor since when I had Google Fiber or CenturyLink even when running Tor relays I never got those complaints. I use a MikroTik core router so maybe it got malware, although I recently updated it from 7.15.3 to 7.16.1. I decided to filter the prefix. Maybe a Windows PC on our network is infected. Maybe it's my Rocky Linux servers. Should I probably get a Supermicro/Deciso box and run an OPNsense firewall instead? But I never got complaints from Frontier or Optimum when I put MikroTik routers on both ISPs too, that for accounts not in my name. Maybe it's a false positive and just TCP forgery pretending to me be (I hope so). Just letting you know. -Neel === REDACTED COMPLAINT BELOW === Dear Verizon Online Customer, On 10-30-2024, your account was reported to have been used in an attempt to gain unauthorized access to another system, or to transmit malicious traffic to another Internet user.

[Including - computers, tablets, cellular devices, network attached storage, security camera recorders (DVR or NVR), and IOT devices, where possible.] Additional information and removal guidance of detected malware may be found on the website of your scanner(s) manufacturer. It is difficult to verify the presence of an exact virus or malware infecting a device without a full system scan with up-to-date software. Installing the most recent firmware and software updates can also assist in securing your device(s). Please follow the device manufactures processes for any updates. If you are unable to take immediate action, it would be advisable to remove the device(s), which may be infected, from your network and the Internet connection until it has been properly cleaned. This may be easily done by unplugging the network cable that connects the device to the router. For wireless devices removing power from the device will keep it off it the network.
