P2P Spam?

Sgt York writes "In a NYT article (republished in the Houston Chronicle, no subscription required) experts at CERT, F-secure, Trusecure, and the Hall of Justice (see article) think that SoBig.F is a spam scheme in the making. They say that SoBig.F is the 6th variant in an ongoing experiment with the possible goal of setting up a distributed spam network, to be rented out to the highest bidder. If that is their goal, they are well on their way. Another disturbing note in the article is that "In the case of four of the six programs, a new version was launched immediately after the self-timed expiration date of the preceding one". SoBig.F expires in two weeks. "

    I think the superheroes involved in the SOBIG fight miss the entire point.
    The authors are probably testing the feasibility of sending out a virus (which
    given the number of copies I receive) will happily be opened by people and
    then simultaneously sending out spam messages to the same group of people.

    There's no need for the SOBIG authors to control the machines after SOBIG has
    been executed. They just need to include the spam message in the virus
    itself.

    That would make it truly P2P spam. Unsuspecting user X who opens SOBIG would
    transmit the mechansim for sending more spam and his portion of the spam
    deluge. Of course there could be a downside to all this, once the blacklist
    people start cutting off EVERY ISP in the world because of spam messages SOBIG
    would defeat itself because no one would be getting mail.

Every time a virus is exposed that tries to download from some fixed location, I've wondered why virus writers would even try such a thing, when it's obvious that white hats will reverse-engineer their code?

    What if the next version uses something more flexible... like a Google search on some particular string? Spend a few months sprinkling links to the download on servers around the world, with pages containing some unique string (call it "foo123"). When the next virus activates, it does a Google search for "foo123", and downloads its replacement. As fast as hosts are removed, more can be created and indexed.

    For even better effect, use a moderately common word or phrase that Google couldn't remove from its index without causing big problems.

When the next virus activates, it does a Google search for "foo123 [google.com]", and downloads its replacement. As fast as hosts are removed, more can be created and indexed.

      OK, let's see how you would do it...

      The payload of the original virus would be a encrypted peer-to-peer daemon somewhat like Freenet, except that it would only allow uploads signed with a particular digital signature. The client would of course have to include the public key of that signature, but not the private key.

      Once infected a machine would open a listening port and attempt to connect to machines chosen randomly but with a bias to its local class C (as with CodeRed). Once contact has been established the machines would exchange IPs so that each could recontact the other. Each machine would continue to probe for peers until it had found a certain number - say twenty - and then it would remain quiescent, just listening. Periodically (say weekly) it would handshake again with its known peers, and if any failed to handshake twice successively it would seek others until it had again reached quota.

      Once the virus was widespread the author would send a signed file to one infected machine. The name of the file would be a unique string (for simplicity of exposition say a serial number, although any systematically unique string would do) so the first file the virus author injected might be 0001, the next 0002 and so on. The machine would accept the file as genuine because it could decrypt it with its local copy of the public key, and would pass it on unchanged to all the other infected nodes it knew about. If a machine had already received 0001 and was offered 0001 by a peer it would refuse it to save time and network congestion - not to be nice to other users, but because if the thing blocked up network bandwidth completely, it wouldn't be able to do it's own dirty work.

      The signed files could contain

      1. a list of targets and a date/time. When the action date/time in the file was reached, the virus would mount a DDoS attack on the hosts listed in that file for twenty four hours and then delete the file.
      2. the URL of a file to load and then spam out in the same way the virus itself originally spread. Because this file doesn't have to be put up before the virus is launched it could be put up on any defaced site anywhere and need not be tracable back to the author.
      3. a hotfix patch to the virus itself, which would immediately be installed and run.

      This would be incredibly difficult to defend against because

      • in DDoS mode the hosts to be attacked wouldn't be known until the attack file began to propagate - and it could propagate very, very fast indeed, since the peer-to-peer network has connected itself in advance.
      • It would be impossible to introduce 'white' payloads into the network because only the author would have the necessary private key.
      • Because of the upgrade facility, as defences against the virus became available the author could inject into the network 'hot fixes' which would work around these defences.
      • Because the author could inject new signed files into any infected node, it would be very difficult to track down where they were being injected.

      Furthermore, the network could be used to launch several sequential attacks, which would not even need to have been planned at the time the virus was written. The author could, in effect, sell use of a flexible, massively distributed mass-UCE/DDoS attack engine to the highest bidder...

SMTP is collapsing in complete disarray, as fittingly exemplified by failing dead last [samag.com] [samag.com] in the recent Sys Admin comprehensive networking test.

    You don't need to be a Kreskin [amazingkreskin.com] [amazingkreskin.com] to predict SMTP's future. The hand writing is on the wall: SMTP faces a bleak future. In fact there won't be any future at all for SMTP because SMTP is dying. Things are looking very bad for SMTP. As many of us are already aware, SMTP continues to lose market share. Red ink flows like a river of blood. SMTP is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time SMTP developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: SMTP is dying.

    Let's keep to the facts and look at the numbers.

    SMTP leader Theo states that there are 7000 users of SMTP. How many users of SMTP are there? Let's see. The number of SMTP versus SMTP posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 SMTP users. SMTP/OS posts on Usenet are about half of the volume of SMTP posts. Therefore there are about 700 users of SMTP/OS. A recent article put FreeBSD at about 80 percent of the SMTP market. Therefore there are (7000+1400+700)*4 = 36400 SMTP users. This is consistent with the number of SMTP Usenet posts.

    Due to the troubles of Walnut Creek, abysmal sales and so on, SMTP went out of business and was taken over by SMTPI who sell another troubled OS. Now SMTPI is also dead, its corpse turned over to yet another charnel house.

    All major surveys show that SMTP has steadily declined in market share. SMTP is very sick and its long term survival prospects are very dim. If SMTP is to survive at all it will be among OS hobbyist dabblers. SMTP continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, SMTP is dead.
