      If I read this correctly, if you take part in a DDOS attack also known as "Slashdotting", it takes just a single trigger-happy sysadmin somewhere on the way to knock you and the rest of us from the participating networks.

      The article is pretty vague, and if I read correctly, there _is_ a human factor involved. Of course, humans are better from machines from telling apart a bone-fide Slashdotting (beh, a "bona-fide" DDOS attack :p ) from something that's meant just to destroy.

      However, our bona-fide attack just took their server down. We're entering a gray area here: is it still a legitimate flash crowd? It's often hard to tell. The problem is, until today, the one who used to lose was the affected server. If enough backbone ISPs will join this alliance, it will be us getting hurt by the collateral damage.

      No, a denial of service against a web server such as a syn flood or a resource attack doesn't look like /.ing. When a /. event occurs, the clients actually try to complete the TCP connections and HTTP transactions. The flow of data is two way. Think about what HTTP looks like from a packet perspective. From client to server, the initiation of the HTTP session, small packets to the server signifying GETs and POSTs or TCP ACK, and more data from server to client returning pages, images, etc. It's a pretty well known behavior.

      In a denial of service like a syn flood, there are a bunch of incomplete TCP handshakes, often from the reserved address space. In a resource starvation attack, the TCP may complete, but the client doesn't actually send any traffic to the host, in the case of an HTTP transation, would be a GET or a POST--so you get a TCP set-up and then nothing else.

      In a /. event, what Peakflow will is a a spike in traffic but it will also see that clients are attempting transactions and they are coming from valid addresses (non reserved). That looks different.

  12. Internet automimmune diseases by G4from128k · · Score: 4, Informative

    Initiatives such as this one are part of a move toward an internet immune system -- active systems that watch for and halt undesirable activities. But like the mammalian immune system, it will doubtless be subject to false positives. This raises the potential for auto-immune diseases such as when someone's IP is inappropriately blacklisted.

    The core of the problem will be a disconnect between the fast response time required for properly halting fast-spreading malware (e.g., a compact worm that attacks even just 1% of hosts will probably double its infected base every second and saturate the entire net within a minute) and the slower response times of human-mediated due-process procedures. The need to quickly halt infections will lead to a hair-trigger system that may shutdown innocent hosts or kill legitimate activity.

    Internet auto-immune diseases are potentially quite serious as that actually create a serious new vulnerability. Criminals could try to trigger an immune response on a target and trigger an immunity-DOS response on the target by using the system against itself.

    Ok, Peakflow SP tracks and reports on network flows and the associated data gleaned from a flow such as src/dst IP addresses and ports, bytes transferred, duration of flow, etc. It does't capture packet data (though you can do that on a limited basis). A flow is a unique network transaction that starts with the first packet from a source to a destination and ends with either a time-out(no packet sent) or in the case of TCP, a close sequence (RST, FIN).

    What is interesting about this is that traffic like DoS/DDoS attacks port scans have unique network fingerprints. For example, a DDoS attack is a large amount of traffic to a single source, often without any return traffic. That is unusual. Sure, the /. effect might trigger a DoS alert, but someone has to go investigate the cause. Besides, how many sites get /.ed on a daily basis? But in general, flash traffic would be seen.

    What this means for service providers, hopefully, is that they can more quickly respond to attacks and improve the general health of the networks they manage by locating the source of the malicious traffic more quickly.

    First of all, some more details about this project can be found here.

    There is nothing new about the idea, in fact, it's long overdue. There is however something new in the idea having a practical implementation. The problem so far was that various network operators use very different hardware and software to monitor their networks (if at all..), thus, the idea of a 'fingerprint' may vary. Sharing becomes difficult.

    By standarlizing on one platform (Arbor Networks PeakFlow SP), this becomes possible. All operators have the same device, which, coupled with this functionality, can finally bring this idea to life.

    PeakFlow SP are Intel/OpenBSD boxes with additional Arbor software. They do however retail for 120,000$ per collector unit, and a collector unit can only proccess data from up to 5 devices (usually routers which export NetFlow formatted data). This is quite a steep entrance fee to pay for the pleasure; and many of the smaller players will never be able to afford this.

    In fact, it's all not much more than clever marketing for overpriced Arbor devices; without the initiative, you can easily look toward other products (Cisco GuardXT, ex-Riverhead, many others). With the initiative, you now have a bit more of a reason to send $120,000 to Arbour.

    Expect every security vendor to have a similar central fingerprinting repository soon. Non-compatible with one another, ofcoure.

    If they would but do it this coalition could expand their concern to the detection and prevention of zombie spam (that is, abuse of systems within each provider's IP space as zombies) they could begin the process of eliminating spam. Not dealing with spam, eliminating spam. It's long past time for that.

    The great unexploited opportunity for eliminting spam is at the intermediate level (that is, ahead of the destination server for the spam.) If they had been implemented in sufficient numbers at the appropriate time (with "sufficient numbers" being below 1% of all IP addresses) open relay and open proxy honeypots could have eliminated spam - before the spammers had a chance to advance to zombies.

    The great anti-spam opportunity is still at the intermediate level (where distinguishing spam from valid email isn't necessary - no valid email follows the path spam takes.) At the intemediate level anti-spam actions can easily be 100% effective, 100% accurate. No spam delivered, no valid email (of which there is none using that path) wrongly stopped.

    All it would take would be for ISPs and others to detect the abuse and then act against it - in all the ways they can or in all the ways they choose (some, for instance, might cling to the "only blocking is good" philospohy. OK, let them only block - it still is productive, even though it's way less so than interception, since the spammers can simply choose another abuse path when they experience blocking. For interception the spammers first need to learn that the spam is bieng intercepted. It's always good to make life harder for the spammers, to add to their burden.)

      "Spam currently follows a pretty recognizable pattern on the internet. That does not mean zombies could not be programmed to send spam in a less recognizable way, or in a way that mimics normal e-mail usage. This could slow down spam, but I doubt it is a good long term solution."

      It's always going to be packets in to some IP address, always going to be packets out to port 25 at some other IP address. The nastiest technique would be to have a local network of zombies so that the incoming packets go to a different IP address from the source of the outgoing packets to port 25 - and at some appreciable time delay after the receipt of the packets that control the zombies. That's part of why I think that an ISP-level counter-attack is needed - single IP address monitoring might be inadequate.

      If spam were a low-level abuse then that would be a fairly formidable problem. With the huge volume of spam as it is detecting the abuse is far easier, is it not?

      The article talks of sharing the "fingerprints" of the abuse, which seems to indicate that one of the design goals is to anticipate and provide for a constantly-changing pattern of abuse rather than assume a fixed pattern.

      In any case the mere fact that the proposed solution is based on a cooperative approach rather than on a collection of individual approaches is, IMHO, a step forward.

      If a host begins talking on port 25 did a worm just start spamming or did the user sign up for a new e-mail account?

      What's the destination of the port 25 packets? In general I don't wish to examine packet contents, only size and ports and IP addresses. For abuse packets my feeling is that the ISP has a complete right to fully examine them - the ISP is acting to protect itself and is not intercepting valid traffic.

      The easiest traffic to spot is the worm propagation traffic that compromises machines in the first place.

      I won't argue, although a bunch of port 25 traffic going elsewhere shouldn't be that hard to spot. If the spammers spread the zombies out so much that each need only carry a tiny bit of spam traffic (keeping the volume down and making it less detectable from port 25 volume) they also potentially hit more IP addresses for which port 25 traffic volume isn't the only criterion. In any case I think they hit zombies less hard than they used to hit open relays and open proxies, although that is an opinion backed by no data at all (other than what I know about how heavily they hit some open relay honeypots.)

      The trick is making it cost effective for ISPs to notify users.

      I'd like to see far more effort by ISPs to notify the ISPS of the sources of the abuse. Which appears to be (in part) the nature of this new plan, if the source ISP is a participant. Spam abuse is an internet-wide problem, not a single ISP problem. There needs to be effective cooperation and timely sharing of information about abuse as it happens.

      Some countries are starting government agencies to deal with spam and worms. ISPs can easily provide them with a list of infected hosts that they can contact with the appropriate worm remedy.

      Ah. Exactly.

      The problem is mostly logistics and funding, the technical part has been solved for a long time. I see this as the most realistic solution to spam zombies.

      I think the biggest problem, dwarfing logistics and funding, is the human problem. It is in fact very difficult to get those in charge of security to look outside their own domains, to consider anything beyond what they've already chosen to do. Most prefer a combination of blocking and of sternness towards their own users who operate compromised machines. This after the ISP blithely, inattentively, and unconcernedly delivered the packets that caused the infection. "All the fault lies in the users" could be their motto, "never in us."

      System administrators almost all treat spam as a single-system problem to be handled at the destination server (the single system.) It is nearly impossible to persuade anyone to act against spam earlier in the spam path (and when they do act it is almost entirely a combination of blocking and "blame their own customer for the abuse committed by the spammer.") You can see the result: spam continues to flow.

      Thanks again for your comments. Do note that I'm strictly a loudmouth: I'm doing nothing at all to fight spam. I gave it up in January.

      OK, I did something incredibly tiny: I just looked to see if ZoneAlarm was still logging proxy port attempts (which could indicate a continuing volume of open proxy spam: if it is spammers looking for proxy ports they're doing it to find a way to send their spam.) I found 3, all to port 8080.
