Sla.ckers getting DoSed
Posted by: rsnake

sla.ckers.org is undergoing a pretty significant GET request DoS. Here's the guy who's doing it:

Non-authoritative answer:

If you notice some periodic slowness or odd site behavior, that's what's going on. We appear to have got it mostly handled at this point, but we are doing some work to keep the idiot at bay.

I've never been DoSed, so was wondering if someone is attacking say on an Apache/Linux box what measures can be taken to prevent or mitigate the attack?

It really depends on your architecture. We didn't stop it with Apache, we stopped it with a firewall and some crazy custom rules. But it will depend completely on the form of the attack, so unfortunately the answer is "it depends".

as RSnake said...depends.

This DoS was resource based, so they were trying to maximize the number of httpd threads (though they are probably too stupid to realize what they were trying to do...) and have the server load deny service to other clients. We've optimized the server to handle a lot of threads at once, so that partially helped, but given enough attacking hosts it doesn't matter what you've done on the optimization side.

It's not the first DoS we've had, and of course people attack the server every day in other ways, so we've built some pretty cool defenses. But during moves and upgrades we had dropped some of them, so it was simply a matter of tweaking rules and reimplementing some defenses.

as a weak anti-DDoS, i used to aggregate source IP, and if a subnet (ie : 69.158/16) was sending way too much request, pf started to drop him, until the req/s came back to acceptable level. that's using a whole panzer armee for a single student, but it has proven efficient

yeah I could make it slightly more efficient by aggregating subnets, but the firewall wouldn't have trouble with 100x what it's doing right now, so I'm just leaving it.

I also rarely expire shit, so that's another thing I need to work on, if someone finds themselves blocked after sending legit traffic pm or email and I'll remove your address.

So after doing some more analysis here's how this whole thing shakes out. 22% of our IP traffic on sla.ckers.org was robotic and had bad intentions. That's not good. After re-implementing the security we should have had anyway, we are down to around 1%. Much better.

In other news the attacker in this particular DDoS has been removed by his ISP:

@rsnake

Nice1 glad to see some ISP's doing things right.

On a side note, have you checked the forum search facility for SQL characters such as "_" these can create DOS issues on a large dataset. I'd suggest limiting search to registered users or maybe limiting the date range or only allowing single forum searches.

knowing the GET scheme the forum use, we could try to to display repeatedly a huuuuuge page to exhaust the bw. we could even try to bypass the cache by randomly adding, removing the number of displayed thread (if the cache is on HTML level, not object level of course)

hey, new contest ! bring a sla.ckers sandbox on its knees. that should harden the mainline a lot, and i am pretty sure we could find interesting protections scheme on the way :)

I wouldn't mind trying a resource dos on an isolated box, but it will generate a lot of traffic, and this server is still at a partner company's facility, so we're not going to do that right now. (we're moving it when I get back to TX)

Here's a graph of the last dos, you can see by the incoming (green) line where we shut it off. The outgoing traffic (blue) would be the real problem. Although the extra 500-600kb traffic isn't huge, the line isn't either, and they are running a business on it.

i wasn't specific on ressource DoS, which we can obviously at best mitigate. but a legitimate request overflow will still grind a service to a halt (my uk coworkers discovered this when our new apps hosted on fat bunch of X4600-M2 started to punch request in their oracle db (which, of course, couldn't go down, 'cause it's AIX and oracle, and it's professional. linux can't consume all our resources, ha !) until the box raised white flag.

but what about a more generic free-for-all contest ? up a small server in a VM, regenerated every hour or so, with full logging of activity from outside ? maybe we'll find some creative stuff.

The attack continues... Cyberhacker665 is again DoSing us. This time it was 350 IPs instead of the 70 or so we had last time... 350 and counting. The site appears to be stable for the moment, but we are keeping a close eye on it.

Yeah I noticed service was down early this morning (aus time) at about 10-11 :\ thought it was another DoS >_<

IMO, DoS him IRL, break his arms. That'll fix him.

You know if he is using some Botnet, has hacked 350 webservers or just XSSed some large website and you get hit by their users?

I don't have time to figure out which guy it was, but I've updated fu.ckers, we parsed a lot of bad activity though and now there are almost 12k blocked hosts. This guy was only coming from ~500 hosts I would guess.

I'm headed back to TX today, and I'll try and move the site sometime this weekend or early next week, at that point I can put in some more reliable protection.

Just a question for my edification. How are you blocking IPs and not removing access from large ISPs. For example: AOL (I know don't go there) sends everyone through a set of static proxies. To help balance the load on these servers, the user's IP can change from request to request, all transparent to the user. How are you preventing blocking of the entire AOL community? Other ISPs do the same.

This isn't AOL, trust me. Believe it or not it's far easier than that. He's just using a messload of proxies to hit us to distribute the load. It's one of the dumbest attacks I've ever seen, but it's almost effective because of the sheer volume. Thankfully we're blocking it so it's not that big of a deal.
