Impoverish a Spammer Today

esj at harvee writes "Recently the Camram project released its latest version of a hybrid sender-pays anti-spam system. The project has proven that sender-pays works and has demonstrated how to make it work with existing e-mail systems. Camram has developed hybrid sender-pays techniques that scale down to the desktop and up to the enterprise. It's a completely decentralized system that can put spam-fighting power in the hands of individuals. It gives you control of not only the current generation of spam, but also any future commercial spam -- why replace Viagra ads from a scam artist with Viagra ads from Pfizer?"

Aunt Bertha certainly won't think a new key is trivial (whether or not it is), and I expect her to be hurt more than you or I, meaning she'll have reason to do it more often. Plus, in some PKI schemes, at least, the whole point of public/private keys is to centralize the public keys, so I don't have to email you to get yours. If such is used, it's yet another burden on her part, making sure her new key is available (possibly a burden assumed by automated software). And don't forget about updating CRLs either.

      The only true way to fight spam, is to make email less useful. We need to sever global email, and make smaller, more private systems. Your work email will only interact with your employer's mail servers, and maybe a few approved vendors. This will be a bitch if your job is to do research about new products, or if your wife can't reach you on the phone because your daughter is at the hospital, and her email that would have hit your blackberry is blocked.

      The alternative? Let spam take over until smtp email is abandoned because it has become all but useless. The only question left then, will even a single spammer wake up and say "Damn, I used to like email (for some reason other than scamming for money), wish we never killed it." ? I'm fairly certain the answer will be "No".

This is positive because it helps identify the strengths and weaknesses of the system. However, once objections have been worked through and the developers have answered the same questions approximately 10^20 times, a listing of Frequently Raised Objections is appropriate.

    Isn't universal adoption necessary for a sender-pays system?

    For a classic sender-pays system, the answer is yes--any system requiring universal adoption is a non-starter.

    Because of this problem, the Camram project (and probably others) expanded the classic sender-pays model to a hybrid sender-pays model. One of the many strong features of the hybrid model for sender-pays is that it solves the problem of universal adoption. This new model provides anti-spam benefits to the very first user, and the benefits increase as you add users. Hybrid sender-pays lets you incrementally introduce an anti-spam device that will take a serious chunk out of the economic foundations of spam.

    What kind of attacks are possible against a hybrid sender-pays system?

    There are four known attacks on this system. Two of them attack the sender-pays system, one attacks the friend filter (i.e. the white list), and the last attacks the content filter. Content filter attacks are nothing new; we are in the middle of one right now where spammers are trying to bypass Bayesian filters. As the number of stamps increase, the "harshness" of the content filter can increase and eventually the need for content-filtering can go away.

    The friend-filter attack comes from the implementation of white lists by name. If you know the content of the white list, then a simple forgery will let you bypass the filters. The trick of course is determining the content of the white list. One longer-term solution is to move to white listing by public key. Unfortunately, as long as there are folks not using the system, there will always be a need for white-listing by name.

    Attacks on the sender-pays system involve trying to generate stamps faster. The first is the classic hardware accelerator. The best estimate we have for today is a 500 times speed up over software. There are both hardware and software responses to this attack but both responses effectively devalue the stamp or the means of production, which in turn restores the economic balance. The second attack utilizes zombies as a compute array. But if you run the numbers, you'll find out that the number of zombies known, if run perfectly and full tilt, cannot generate enough stamps for all of the spam in the world today. A tremendous number of stamps would be generated, but not enough for everybody. One benefit of zombies being used to generate stamps is that the machines will become hot, slow, and probably unreliable, all of which will be noticeable to the end-user. With luck, this means some people will get their machines fixed and reduce the zombie issue. Again, if the zombies the start generating stamps, one can always change stamp definitions or value.

    How do you deal with large-scale legitimate mail sources (i.e. mailing lists, mail houses, etc.)?

    There are two issues here. Mailing lists don't really have a good solution with the first generation of stamps. The traffic mailing lists generate is fundamentally indistinguishable from spammers, therefore whatever hurts spammers will hurt mailing lists. The answer for right now is to not do anything with mailing lists. Let them send unstamped mail and let the user whitelist mailing lists or deal with the trapped message issue manually.

    In the future, it will become easier to deal with mailing lists because of the second generation of stamps (opportunistic signatures). If the list is signed with its own stamps, then it would be let through without problem. Spammers would still be barred because their signatures would be ignored.

    The second issue is

    Plenty of people already use TMDA, and a TMDA challenge is the worst case scenario if you use the above system. The benefit is that people who are willing to pay hashcash and then sign subsequent messages don't have to worry about getting TMDA challenges from you, and get their messages delivered immediately. It also hedges against sender spoofing for those senders who have their signatures whitelisted (rather than their addresses whitelisted with TMDA).

Hulagu killed all the scholars in Baghdad and erected a pyramid from their skulls. He destroyed the elaborate irrigation system that the Abbasids had established. Iraq became a neglected frontier area ruled from the Mongol capital of Tabriz in Iran. In 1335 the last great Mongol ruler of this region died, and anarchy prevailed. The Turkic conqueror Tamerlane sacked Baghdad in 1401, again massacring many of its inhabitants. He, too, built a pyramid of skulls. Tamerlane's invasion and conquest marked the end of Baghdad's greatness.

    Tweaking the numbers differently can make this kind of system look like it will succeed or fail. Some recent reputable papers have been looking like it's more likely to fail - too many zombies out there, so if the zombies bother to include CAMRAM support, they can win. It's harder for the zombies to win if every message requires computation, but if each sender only has to do the computation once per recipient, and not on every message, then it's way too easy for the zombies. On the other hand, that makes it easier to detect and blacklist the zombies as well.


    It's obviously a bad idea to build a system that only lets a reasonable machine send 10 messages per day - probably even 100 per day is too low, depending on your applications. 1000 is usually fine. It turns out that there are calculations that scale based on memory speed rather than CPU speed, so there's a much lower spread between the slowest non-palmtops and the fastest CPUs out there (like 4:1 rather than 20:1). But even if each zombie can send out 10,000 messages/day instead of 10,000,000, that slows them down enough that you can detect them and kill them (or at least blacklist them...)
