    If AOL really wants to redeem themselves in geeks' eyes, they should include PGP support in the next version of AOL (say that using PGP will reduce the spam in your mailbox and is ideal for protecting yourself from identity theft, yadda, yadda, yadda).

    This is exactly why I think that SoBig is the perfect spamming mechanism. AFAICT, it essentially gets around nearly every non-content-based spam filter (ie Bayesian and SpamAssassin et al).

    By sending spam from an amazing depth and breadth of compromised networks, it forces blacklist operators to go into "block everything" mode, which is so draconian that users of the blacklists will disable them.

    As I posted in another story, if ISPs start blocking outbound port 25, the next iteration of the worm simply uses the Outlook SMTP settings to relay through the official MXs of the ISP. Given the flood of abuse reports, many ISPs (especially larger ones) are simply going to /dev/null abuse reports; they can be reasonably sure that their servers aren't going to end up in blacklists used by a lot of people (because heads will start to roll among the admins who use the blacklists).

    By pretending to come from an address that has at most two degrees of separation from the recipient, they will get around a fair amount of whitelisting (this is exploiting the greatest flaw in TMDA and the like: trust of the From: address).

  7. Re:This is why ISPs are changing their SMTP rules? on P2P Spam? · · Score: 1

    Blocking outgoing SMTP probably won't do much... if it becomes a problem, then the zombies will get a new version of SoBig that grabs the SMTP server configuration from Outlook and route it through those relays. The ISPs get a flood of abuse complaints (moreso than currently), which increases the odds that the big ISPs will simply say, "Fuck it" and /dev/null abuse emails (maybe even do an auto-reply to make everyone think that it's working). By turning enough of the ISPs customers into unwitting spammers, ISPs aren't going to kill 10% of their accounts; since this problem will be more pronounced at the AOLs and Comcasts of the world, no one's going to block their SMTP servers (save for tiny pockets who probably already do). If you're an ISP, you don't want customers who suddenly can't get emails from grandma@aol.com. If you're a business admin, if you try blocking Comcast, you'll be raked over hot coals by senior management who can't send mail to fellow employees from their cable modems at home.

  8. Re:Could be just be a way to harness email address on P2P Spam? · · Score: 1

    It doesn't just scan the address book; it scans the mail folders (which means that if you post to a mailing list or usenet, it can get your address). I wouldn't be too surprised if it scans IE's cache for addresses on web pages that have been visited.

  9. Re:AOL is going to stomp on CI Host on AOL Sued For Over-Zealous Blocking · · Score: 1

    Admittedly, CI Host would have trouble claiming tortious interference (unless they're unable to mail a customer who uses AOL). However, a user of CI Host may well be able to successfully go for tortious interference, especially if they can show to the court's satisfaction that their IP doesn't spam.

    It's called "tortious interference in a business relationship". In some states, AOL may be forced to pay triple damages plus law fees (note, triple damages would cover lost business).

  15. SpamAssassin the best Bayesian filter? on Seven Spam Filters Compared · · Score: 1

    I've been thinking lately that SpamAssassin might have the best Bayesian implementation, with only a slight change.

    AFAIK, most/all Bayesian scanners out there simply tokenize the mail and then use the tokens as the basis of the rating system.

    However, SpamAssassin adds an X-Spam-Status header to all mails (by default), which contains a list of the various tests (regex, network, or Bayesian) that the mail triggered. If SA were to move the Bayesian scan to after all other tests have completed, then this list of tests passed could be (or might already be) considered by the tokenizer for the Bayesian algorithm.

    The benefit to this is that regex's can discern more patterns in the code (or more correctly, equate patterns) and the network tests are fairly reliable. In a large sense, this is using Bayesian techniques to develop a self-adjusting rating scheme the tests. Using this, one could assess, for instance, how much having a host in the relay chain in an RBL influences the spamminess of an email (for instance, a large amount of email originating from SPEWS-listed IPs is not spam; this would imply that SPEWS would have a lower confidence rating in picking out a spam).

  16. Re:SA holds its own even when crippled on Seven Spam Filters Compared · · Score: 1

    SpamAssassin can also auto-learn; a message that scores sufficiently high will be fed to the Bayesian system as a spam and something that scores sufficiently low will be fed to the Bayesian system as ham. This in turn allows SA to develop other tests.

    As much as a hardship as it was for me, imagine paying that much cash to get a degree in Art History or a similar discipline, where about all you can do is teach. NOW imagine how long it would take you to pay off that debt on a teacher's salary... Yikes.

    These may have been cut in budget woes by most states, but many states have setups where, in return for signing a contract to be a teacher for 5-10 years, they'll forgive all state/federal student loans you might have taken out.

    Also, the military will, depending on where your degree is (MD, meteorology, etc.; I wouldn't be surprised if they extend it to MSCS and so forth) forgive all federal and state student loans in return for a few (3, IIRC) years of service.

    Ignorance of the law is no excuse, but ignorance of the activity almost always is.[1] It goes to intent, it goes to motive, it goes to opportunity.

If you are, and you can demonstrate that you didn't know it was happening, you are most certainly acquitted.

    In a criminal case, ignorance of the activity is a defense. In a civil case (which, afaik, all of these are), that may or may not be the case.
