Snowball Challenges were dumb too.

Yes agreed. The only time something good ever came of it was when Apotheosis wrote up what is colloquially known as Douchebag In Gensokyo, and that could have easily been written without a Snowball Challenge being involved.

Sorry for the downtime. I got a very fun email that Triela was being rude and harassing other poor server hosts as part of a DoS. Turns out, despite firewalling off the ports on memcached from day one, our server was briefly hijacked and proceeded to spew about 2TB of data out in the course of 10 hours today.

I've resecured the box and have immediately depreciated a few things. While it doesn't look like they actually got any significant access, the nature of the attack at least means they managed to have some sort of arbitrary code access through the web server process. They did not, however, seem to get anywhere past that.

I have immediately removed the long derelict frontpage, and the IRC web client is down for the time being pending redesign. I've also forcibly upgraded all of the MediaWiki instances (DMF, Help Me!). The conwiki I have not made any changes to, but if I see any suspect access I will be forced to migrate it to another platform, as it looks like MoinMoin is very dead :\

If there's any problems, please let me know. :3c

I'm not quite convinced they even got that far actually. All the traffic came out over IPv6, if they had access why not both? While I did have proper firewall rules in place supposedly to block outside access to TCP/UDP 11211, I'm wondering if there was a flaw that allowed the attacker to bypass it.

At first I just assumed they had to have some sort of local shell to do what they did given the firewall rules, but there's been no evidence to support any sort of access was gained. It doesn't  add up. I've locked down possible avenues as a precaution, and I'll be heavily auditing access and traffic for the next few days regardless.

Oof. Unsecured and hijacked memcached servers have been producing huge DDoSes for at least a week now, but a hijacked memcached server that was already firewalled is definitely a bigger concern.

Nice to see the home page redirect to the forum now.

Yeah I moved the php backend to memcached like... yeeeeears ago. I knew having a completely unsecured service with no authentication exposed to the internet was just asking for trouble. I might be a dummy but I'm pretty thorough when it comes to security xP

I've had firewall rules blocking all inbound traffic to TCP/UDP 11211 except from lo but I guess they managed to bypass that? It's either that, or they got a shell, did nothing except make local calls to the memcached service, but only to attack out on IPv6? Without leaving any evidence or backdoor or anything phoning home? That doesn't make any sense.

So uh, the being logged out problem is back. The very generic message that says "Database Error" "Please try again. If you come back to this error screen, report the error to an administrator." Same way as last time. Sometimes logging in can be difficult and navigating forums while not logged in makes it show up too.

Problem 1:
IPv6 is broken on SMF, found this out a long time ago. Ended up just disabling IPv6 on lighttpd at the time.
When server was reconfigured for nginx in front of lighttpd, IPv6 was reenabled (why did I do this?), although it wasn't actually working due to bad firewall rules.
Didn't realize this and ended up fixing IPv6 access for an unrelated project. IPv6 bug back.
Dropped AAAA record for www.shrinemaiden.org. People still connecting over IPv6. Disabled IPv6 listener on nginx for shrinemaiden.org entirely.

Problem 2:
SMF 2.0 is not compatible with PHP 7.2. Had put in an override to roll back to 7.1 last time this happened.
Override was helpfully overridden by Debian and PHP went back to 7.2. More unfun times.
Did not realize this until I checked the PHP version on a hunch.
Manually reconfigured lighttpd to launch PHP 7.1 instead of the system default PHP.

Problem 3:
Constantly running out of space, database was kinda bloated and wasn't sure why. Cleaned up some stuff but was still pretty tight on space.
Checked the event logs after fixing problem 2 and found this

Cleared error log. Recovered 20GB of space (LOL)
