OVH Warnings
by Dr Gerard Bulger 15 Sep '20

15 Sep '20

OVH seemed to have upped their game with more information than just throwing all traffic into "mitigation" which can result in bad exit status, with no information as to what their systems are detecting as a threat of denial of service attack. For the first time I got an email.no mitigation. Dear Customer, Abnormal activity has been detected on your VPS Attack detail : 4Kpps/2Mbps dateTime srcIp:srcPort dstIp:dstPort protocol flags bytes reason 2020.09.15 19:02:21 CEST <http://51.38.64.136:42845/> my ip:42845 <http://212.22.93.124:25565/> 212.22.93.124:25565 TCP SYN 60 ATTACK:TCP_SYN 2020.09.15 19:02:21 CEST <http://51.38.64.136:39673/> my ip:39673 <http://212.22.93.124:25565/> 212.22.93.124:25565 TCP SYN 60 ATTACK:TCP_SYN Etc Gerry

non-encrypted connections from Tor exit relays
by kirgali＠riseup.net 10 Sep '20

10 Sep '20

hi, generalized question about Tor exit relays and exit relay operators. do some exit relay operators have a policy to prevent connections leaving their exit node via non-encrypted ports (e.g. port 25)? this could be a philosophical position - not even wanting to be in a position to observe users' data passing through the exit node in clear text. or a pragmatic position - hoping that encrypted connections provide some level (even very weak) of plausible deniability in the event that a connection attracts the attention of law enforcement. this is just my thoughts.

SMTP port 465/587
by kirgali＠riseup.net 10 Sep '20

10 Sep '20

Hi, question for Tor exit relay operators. Do exit relay operators allow connections to SMTP port 587 more than port 465? The RiseUp webpage says “SMTP port 465 is often blocked by Tor exit nodes but port 587 is less frequently blocked” (https://riseup.net/en/email/clients) because port 465 is considered deprecated (see RFC 8314). In practice do most exit relay operators allow connections to both SMTP ports? Thanks

OVH Mitigation
by Dr Gerard Bulger 10 Sep '20

10 Sep '20

I know we should dilute our dependence on OVH, but cheap and seem to ignore the fact the machine is an exit node. OVH has a seemingly patented a system to deal with denial of service attacks. I am not sure what they detect but when they do we get this: "We have just detected an attack on IP address x.x.x.x. In order to protect your infrastructure, we vacuumed up your traffic onto our mitigation infrastructure. The entire attack will thus be filtered by our infrastructure, and only legitimate traffic will reach your servers. At the end of the attack, your infrastructure will be immediately withdrawn from the mitigation" To be fair, the automated system takes it off after an our or two. If my tor server is left in this mitigated state, the tor exit gets labelled a BAD EXIT which is something to avoid as takes days to be trusted again. As soon as I get their email I now stop TOR to prevent that embarrassing label, and perhaps doing so stops whatever it is OVH is detecting. Being shutdown for a few hours seems better than being a bad exit. Gerry

Could Zoom be using the wrong dan-tor blacklist
by Eddie 07 Sep '20

07 Sep '20

Starting yesterday (maybe Saturday) we have been unable to initiate any Zoom calls. They just sit "connecting". According to Zoom, there are no issues that would lead to this. My investigation, traces I have run on the server, and using a VPN (on a tablet on my LAN) show the exact same symptoms I had a year (or so) ago with a couple of AT&T sites, which I eventually narrowed down to being caused by the same blacklist by routinely switching IPs and then eventually shutting down my relay temporarily. Is anyone else seeing similar and/or have any suggestions as I rather not have to shut my relay down. Running a multitude of VPNs on my internal machines is not really an option and my relay isn't going to function if I throw a VPN on my server. Cheers.

Looking into it, I couldn't but conclude that it was some sort of phishing scam. When following the link one was asked to provide a lot of information. The webpage seems to be outdated, incomplete and nowhere was explained why they'd scan the internet for anything. All in all, the page looked as "phishy" as it gets.
