If you're a network operator, you probably know much better resources for getting phone numbers. That's not to say I wouldn't like to see ARIN records cleaned up, I fought that battle for a number of years. INOC DBA? Peeringdb.com? puck.nether.net/netops? I hate to say it, but if you're calling the number in Whois or on the front off www.foo.com then perhaps frontline support is exactly who you should be talking to about these issues. The entire purpose of any support organization is to filter to the appropriate folks. The more clue you show in directing your query, the more clue you'll get in response. Also, it can help if you follow the relationships. Consider two regional networks and two international backbone providers, so you have a network path like: R1ISP1ISP2R2 I understand we'd all like it to work that if R1 needs to reach R2 they call them directly. However sometimes calling ISP1 and making them get involved allows them to get the attention of ISP2, and finally them to get R2 to do something. I can't think of a time I wasn't able to get ahold of the right folks when I needed to do so, using publically available information. But then I don't bother people about a few spams, or 1Mbps DDOS's, remain calm when I call, provide lots of information, and have a realistic expectation of how quickly they might be able to respond. Having answered abuse phones off and on for many years I can tell you that's the exception, not the rule. More common is to get someone calling to scream at you for 15 minutes about how you're destroying his livelyhood only to figure out that his box was misconfigured. Funny how you never even get an I'm sorry when that happens. -- Leo Bicknell - bickn...@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ pgpWIPIStUJ1L.pgp Description: PGP signature

Why does abuse handling take so long ?
Dear nanog members, As current maintainer of DroneBL I happen to receive a lot of unwanted packets in the form of DDoS attacks, now the DDoS itself is not the real problem, dealing with it the fast way is. Now most of you would think: Just filter it, put a big firewall in front of it, bla bla bla bla. But what I'm really talking about is the ignorance most providers show when it comes to handling the abuse when it gets reported. The issue in there being, it's way too slow, and my hoster needs to temporary nullroute my ip range in order to protect his network. We both mail all the involved providers and sometimes need to wait days before hostings act upon the mail. In most cases the only thing the abuse@ contacts do as hoster, is relay the mail to the client but do not dare to do anything themself, even if you provide them with a shitload of logs, even if you call them and say that the attack from their source is still continueing, they refuse to look into it and shutdown the source. And that pisses me off badly. Why o why are isp's and hosters so ignorant in dealing with such issues and act like they do not care?

Why o why are isp's and hosters so ignorant in dealing with such issues and act like they do not care? they don't act like they do not care. they really *don't* care. no acting. Well now, I'd say this varies considerably. There are definitely ISPs that care and *do* work hard at reducing abuse. But even so - assuming I'm an ISP that cares, - You're presenting me with evidence of abuse. OK, I don't know you. Why should I believe your evidence? At best I'm going to take it as a *hint*. - If I take your evidence as a hint, I'm going to want to correlate it with my own logs. This takes time. - I probably have customer contracts in place that specify under what circumstances I can actually take the customer off net. My tolerance of abuse may not be the same as your. Also, due process means that these things take time. Steinar Haug, Nethelp consulting, sth...@nethelp.no

And that pisses me off badly. There is a relatively nice way of putting this. If you can't contact the customer and don't know what they are doing, it is difficult to estimate the risk from terminating the customer's connectivity. Therefore, giving them some time to react---4 business hours or perhaps even a business day---seems reasonable, and this can be a very long time span for many types of network abuse, especially when time zones are taken into account. Why o why are isp's and hosters so ignorant in dealing with such issues and act like they do not care? The less nice way is that many hosters attract customers who don't care if they are compromised. These customers do not perceive abuse notifications as valuable, so the hoster gains nothing from forwarding them: the abuse won't stop, and the customer is likely less happy than before.

It unfortunately does not see much use: under 1% of allocations in RIPE's database include any reference to one of only 235 incident response teams, which are conceptually similar to a POC. Other things have been tried but haven't reached critical mass also, such as dial-by-ASN VOIP connectivity. The real problem with handling serious network abuse is it's pretty hard to get through the bozo filter and actually reach anyone who might understand your request or complaint (DDoS), let alone have the power to act. The anti-spam folks have honestly made this problem far, far worse, by slamming every role mailbox they can find for every network operator, regardless of whether or not a specific mailbox for email-related abuse exists or how good (or bad) a network may be at keeping spam off its network. I hope this remark doesn't steer the thread far off-topic, but I wish the anti-spam folks would realize how counter-productive it is to intentionally send the same complaints to a multitude of different abuse mailboxes. For this reason, it really is necessary to have an automatic filtering mechanism in place just to make sure the network abuse people don't have to sift through messages which are mostly related to email abuse. If operators would decide to use a system like IRT, supported in RIPE IRR, then we would not only be able to filter out a lot of the B.S., we would also know that signed messages complaining of DDoS coming in were actually from the security folks at the complaining organization, people who have authority to make requests on behalf of the org that owns related netblocks. This pretty much eliminates the why should I believe your evidence? argument, because we shouldn't have to believe anyone's evidence to at least block traffic towards the netblocks they operate. For example: if I am an end-user with address 192.0.2.80 and my web site is being subject to DDoS which I believe is originating from 203.0.113.66, I would contact my ISP, who registers themselves as the IRT for 192.0.2.0/24. My ISP would probably do a sanity check on my claim, examine their netflow, etc. and then agree that 203.0.113.66 is a source of the DDoS. They'd see that an IRT is registered for 203.0.113.0/24 and send over a PGP-signed message to the counter-party IRT. That IRT would verify the PGP signature and association with the target of the DoS, 192.0.2.80, and at that point, they would have absolutely zero excuse for not immediately dropping all traffic from 203.0.113.66 towards me at 192.0.2.80. It doesn't matter if there are any logs or evidence, it matters that the proven security/abuse contact for 192.0.2.0/24 requested that the counter-party stop sending traffic to 192.0.2.0/24. Whether or not the ISP for 203.0.113.66 decides to investigate any further is up to them; maybe they log some traffic, find a compromised host, and shut it down. Maybe they really don't care. Now that you know people are capable of doing all that based on data in RIPE's trusted IRR database, you may also realize that this process could be streamlined to any point between human reads email, checks relationships, and configures network all the way to script reads email, checks relationships, and configures network. Implementing this could save NOCs time (if they really cared about outgoing DDoS from their networks) and improve response to network abuse. So ultimately, there is already a good framework in place to substantially fix this problem. No one uses it. That is unlikely to change until there is an economic incentive, such as a lawsuit by someone targeted by DoS which can be proven to be originated from a negligent network, causing calculable damages. Until some network has to pay out a million bucks because they sat on their hands, I don't see anything changing. -- Jeff S Wheeler j...@inconcepts.biz Sr Network Operator / Innovative Network Concepts

One of the things you have to remember is that ISP's get a ton of reports, and most of them are of very low quality. Abuse queues are full of people who sign up for a properly run mailing list and then a year or two later mail abuse to get taken off saying its now spam. Or folks who misconfigure their firewall / IDS and send in reports of being DDOSed, by a nameserver, to which they are sending queries and then flagging the responses as an attack. There are a lot of reports that don't include either the source or destination IP, or leave out any time information. Worst of all, there are the automated reports where someone has a different opinion than the law, or even reality. They create systems to basically DDOS abuse@, by reporting every case they can find individually when in fact the spammer is doing things legally and properly. Of course it varies greatly ISP to ISP, depends on customer mix, time of the day, time of the year and all sorts of other factors. Still, there are times when I would say less than 1 in 50 e-mails received to abuse@ is something that is a complete report and actionable Keep that in mind, along with what others have pointed out, that there is generally no profit in handling abuse. Quite frankly, most ISP's aren't going to take your DDOS report seriously via e-mail. If it's not bad enough to you that it is worth your time and money to make a phone call and help them track it down it is not worth their time and money to track it down and make it stop. In short, try picking up the phone. You'll bypass the entire e-mail reporting cesspool I just described, and show the ISP you actually care. 9 out of 10 times they will respond by showing they care as well. -- Leo Bicknell - bickn...@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ pgpvjeuh7yw89.pgp Description: PGP signature

Quite frankly, been there, done that, got the t-shirt. And the answer I get most of the time there is: [loop] - Sorry, email abuse and wait for a reply - Sorry, I can't help you, wait for a reply on your abuse email - Sorry, there is nothing I can do, my hands are bound, wait for a reply from the abuse department [/loop] So much regarding the 9 out of 10. It's the 1 remaining that actually cares and tries something. signature.asc Description: OpenPGP digital signature

In my experience, most phone calls cause the ISP to become immediately hostile. They find abuse report phone calls extremely threatening / scary / etc. and go into full shields-up mode. 9 out of 10 times the very first words out of their mouth is talk to our lawyers. the remaining 1 out of 10 is block it on your end. Email tends to be non threatening. As useless as it tends to be, it is still generally better than calling. the real cesspool is POC registries. i wish arin would start revoking allocations for entities with invalid POCs.
Re: Why does abuse handling take so long ?
Depends on what you're yelling at them about and what you tell them. I've picked up the phone and had a NOC guy at a russian SP (can't remember which, Caravan I think) kill off a syn flood that was hitting us promptly, at like 1 AM their time.
