Hello all, those watchdogcyberdefense "specialists" have meanwhile publicly admitted their mistake (of course, hidden in a political wording to create a different impression): https://watchdogcyberdefense.com/2024/11/is-this-attackers-ip-spoofed/ Quote: "This experience got us thinking about the need for a swift way to identify spoofed IPs involved in attacks that create substantial backscatter traffic" On November 8, 2024 at 4:44 PM, <tor-operator(a)urdn.com.ua> wrote: gus : > I'm writing to share that the origin of the spoofed packets has been > identified and successfully shut down today, thanks to the assistance > from Andrew Morris at GreyNoise and anonymous contributors. Are you sure that it has been effectively shut down? We're still receiving spoofed packets with IP addresses of Tor relays set as source after this message has been posted. We've also received more "reports" from the same newbies after this message was posted. Our traps even see packets with the IP addresses of Tor relays that are in the same subnet. So far we've been able to trace this to a certain peer, we'll be monitoring. _______________________________________________ tor-relays mailing list -- tor-relays(a)lists.torproject.org To unsubscribe send an email to tor-relays-leave(a)lists.torproject.org -- Sent with https://mailfence.com Secure and private email

Furthermore, an identical email was received on a server operated by me, Running I2PD. The email originated from watchdogcyberdefense.com, which is hosted on a server located in the Philippines. Additionally, the company has published an article on this matter, which can be accessed via the following link: https://watchdogcyberdefense.com/2024/11/is-this-attackers-ip-spoofed/.

Inquiry about a possible DDoS case
by Jose A 07 Nov '24

07 Nov '24

Hello everyone. I have received a communication from my ISP regarding the IP where I have a Middle Relay and a Bridge, informing me that this IP is being used for a DDoS attack. I have checked the servers and everything is correct; there are no strange processes running. I have run various tools and everything seems to be in order. Therefore, has anyone encountered a similar case? Or even better, could someone be using Tor to carry out DDoS attacks? I am a bit puzzled by this situation. Thanks for your time King regards JAC -- Sent with https://mailfence.com Secure and private email

Meanwhile 3* OVH abuse report (twice the same, once for 2nd IP), Virtarix, ServaRICA - all from the same watchdogcyberdefence folks. I have replied to all above ISPs, no suspensions so far. Just received a suspension note without ANY explanation from AvenaCloud - opened a support ticket with them...

And I have received a new "abuse" report from Hetzner raised by the same bozos at watchdogcyberdefence, but this time purportedly aimed at FTP port 21. I've told Hetzner they are welcome to monitor traffic coming out of my node to reassure themselves that this is nonsense.

Hi, So I am wondering, is a Raspberry Pi 4 a recommended device to run a tor relay on? In terms of traffic load, etc? Thanks. --Keifer

Please check if your relay has fallen out of the consensus
by Roger Dingledine 02 Nov '24

02 Nov '24

Hi folks! We're hunting down a mystery where two of our big university relays are having troubles reaching the Tor directory authorities: https://gitlab.torproject.org/tpo/network-health/analysis/-/issues/86 Can you check to see if your relay is in a similar situation? In particular, the situation to look for is "Tor process is still running fine from your perspective, but, relay-search (https://atlas.torproject.org/) says you are no longer running." If your relay is in this situation, the next step is to check your Tor logs, try to rule out other issues like firewall rules on your side, and then (if you're able) to start exploring traceroutes to the directory authority IP addresses vs other addresses. If you need more direct help, we can help you debug or answer other questions on #tor-relays on IRC. Thanks, --Roger

"When you pay peanuts, you get monkeys"
by mick 01 Nov '24

01 Nov '24

Hi there. I found the title of the above blog post highly ironic. I run a Tor relay (middle and guard node). You appear to be sending automated "abuse" reports to other ISPS as a result of what is obviously (well obvious to anyone who studies the network traffic properly) spoofed source address connections to SSH port 22 on random servers around the net. These "abuse" reports cause the ISP hosting the /real/ address of the spoofed server to do one of two things. Either they just pass the report on to the server admin for investigation, or they simply shut down the srevr in question and lock the account of the operator. In either case the perfectly innocent Tor server admin is highly inconvenienced and the bad actor(s) doing the spoofing scans get the Tor relay addresses blacklisted. This is detrimental to the health of the Tor network. Please look carefully at your automated abuse reporting system and add some intelligence to it - preferably by getting a properly skilled network administrator to look at the traffic /before/ firing off a spurious report. (Oh and BTW, SSH scanning at scale is so much part of the background noise on the 'net that I am astounded that you should pay much attention to it at all. I don't.)

My own write-up and explanation (and speculation) is available at https://delroth.net/posts/spoofed-mass-scan-abuse/ as a reference. I've had a few people email me saying they had the same scare moment after getting an abuse report and they ended up finding my article, so I'd like to think it's already helped a bit! I also received an email today from Hetzner's legal team saying that they have read my article (props on them, I didn't send it to them myself!). They are monitoring the situation on their side and emphasized that they do not usually take action on this kind of reports they have recently been forwarding to Tor relay operators. So at least for others hosting relays at Hetzner I don't think it's worth worrying too much. For other hosting providers, your mileage may vary. _______________________________________________ tor-relays mailing list tor-relays(a)lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays -- Sent with https://mailfence.com Secure and private email

[tor-project] Reminder: mailman 3 upgrade imminent (TPA-RFC-71)
by Antoine Beaupré 29 Oct '24

29 Oct '24

Hi, As mentioned in early October, we're in the process of upgrading our main mail server, which includes upgrading to the shiny new Mailman 3 platform. We have, right now, a prototype mailman 3 server available at: https://lists-01.torproject.org/ It's hidden behind the usual "trivial" authentication (ask us on IRC if you don't remember what it is), but should otherwise work normally. I'm going to start by migrating the TPA mailing list and we'll be testing this for a couple of days, but, next week, I'll start migrating the other mailing lists (including this one!). If people want to jump in front of that train early and be part of the beta testers, then by all means I'm happy to have your mailing list be part of the early adopters. Be warned that Mailman 3 is a significant upgrade from Mailman 2. There are some great things (like unified authentication), and some less great things (like a more complex design and "shinier" web interface that might not be everyone's taste). As a reminder, we're doing this upgrade a little rushed because the main mail server is now unsupported for security upgrades. See the details of the proposal here: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-71-emerge… ... with the milestone tracking actual work issues in: https://gitlab.torproject.org/groups/tpo/tpa/-/milestones/16 (Sorry for cross-posting this, but this seems like it warrants wider distribution. As a rule of thumb, I selected mailing lists with public archives that had posts in October 2024, removing duplicates like anti-censorship-team and -alerts. I also suspect many of those mailing lists will refuse my message because I'm not subscribed, but I will have tried. :)) Phew! a. -- Antoine Beaupré torproject.org system administration _______________________________________________ tor-project mailing list tor-project(a)lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-project

As an update, once I showed the link from OONI to my ISP, they offered to move my server to another location at no charge. So the Tor server was moved from India to the UK. (Actually, I built a new one from scratch.) So I will mention here this ISP - Contabo.com - for their great customer service and understanding of what Tor represents. They have automatically and temporarily blocked my IP address - and informed me that they did - 2 or 3 times in the past because they felt it was under a DDoS attack, and I'm OK with that. At one point, communicating with their support team, one person even wrote this to me: We are glad to support your efforts in maintaining these relays, as they play a crucial role in fighting censorship and promoting internet freedom. Thank you for your ongoing trust and partnership. I initially chose them because they have few exit relays (only 12 as of today, 4 of them being mine, but there are about 100 other non-exit relays). With that kind of service, I'm wondering why they are not more popular for exit relays.
