An anonymous reader writes "Commtouch released its Email Threats Trend Report based on the automated analysis of billions of email messages weekly. The report examines the appearance of new kinds of attachment spamsuch as PDF spam and Excel spam together with the decline of image spam, as well as the growing threat of innocent appearing spam containing links to malicious web sites. Image spam declined to a level of less than 5% of all spam, down from 30% in the first quarter of 2007; also, image pump-and-dump spam has all but disappeared, with pornographic images taking its place."

      Gmail's spam filters have definitely improved. When I first got my account (in '03?) I foolishly posted something to Usenet via DejaGoogle (required my @gmail.com account) and the spam just started rolling in. I still get lots of spam, but almost all of it is properly routed to the spam folder, and thanks to the CustomizeGoogle extension, I don't even see the spam count.

      They're good, but they're not that good for me. I get several spams a day in my inbox (and thousands a day filtered out).

      Bizarrely, they should be easy to identify. Most of them are in Russian. Whatever bayesian network they're doing should have figured out by now that I don't read Russian.

      The other one is the same template, over and over, all beginning with the same phrase. I have no idea why that one keeps getting through.

Thunderbird's and Gmail's filters seem to do almost all the filtering perfectly these days, but even checking the size of my inbox against my junk-boxes, I have to say that I'm getting nothing like 95%. Not even 50%.

    • My gmail account had 535 spams in the last 30 days against 20 genuine emails. So that's roughly 96%. My gmail account name hasn't been splashed anywhere public, I only use it for companies that require an email for registration and with friends. The account name is 10 characters long and won't appear in a dictionary anywhere.

    Since most slashdotters are libertarians for some reason (and I could argue even I am to some degree) my question is: where's the technological efficient solution to this.

    We've seen some "free market" solutions which basically required that you pay a fee to every mail provider so they don't trash your email. And this didn't particularly help spam either.

    I come to the conclusion that spam as an issue is one of two things, or both of those things:

    1) Not that big of a problem (hard to believe if you are a mail provider / ISP yourself)

    2) Impossible to solve by means of free market solutions, and requires cooperation and standardization of new technology.

    Point 2 is hard to happen since every little startup that comes with a mini solution, trumpet it on their own and hence they are only a nuissance to deal with in the big picture (due to lack of a single standard, it's impossible to have clients which make the process of whitelisting easier and even half automatic).

    Here are couple of solution which would get us half-there, but are only quarter-implemented right now:

    1) Whitelist SMTP servers by talking back to the supposed mail of origin and comparing IP-s. The SMTP may return list of IP-s this host responds from. This is then cached and used for further authentication on this domain. It *may* lead to DoS if many hosts do a first-time check simultaneously, but it's unlikely (and less problematic, given we're eliminating 95% of bad emails this way).

    2) Test-for-human-intelligence in your first email to a new email. Such as, I don't know, some sort of CAPTCHA you fill-in? Once this is done, communication can proceed without further tests between those two emails. The receiver still has the option to block you, lest you employ a mechanical turk.

    Those solutions are boring, they're incomplete in a way, they introduce hassle, but if we *all* agree on those, they can be made less of a hassle, and still not lose their efficacy.

    That would require the likes of AOL, Hotmail, Gmail and so on free mail providers to cooperate with the likes of Microsoft, Apple, Linux devs and so on, to implement this on both the clients and servers.

    Right now, I could see Hotmail cooperating with Microsoft (.. wink, wink.. :P ), but that's where it ends.

      I'd say the agreement that needs to be made between us is to start shunning ISPs who behave so impolitely. Email is a commons, and subject to the tragedy of the commons. The solution to the tragedy of the commons is politeness.

  • We can't stop it because we aren't addressing the real problem. Spam is an economic problem. People send out spam because they make money off of it. And they will therefore continue to send out spam as long as they make money off of it.

    If you want to stop spam, you have to remove the economic incentive. To do that, you need to cut off the co-conspirators that are allowing the spamvertised domains to be established and hosted. If you can either prevent them from getting a cut off the action, or punish them severely for taking their cut, then you can stop spam.

    Until then, if all we do is try to filter spam out, we'll just continue to see the costs of inaction. Beyond that, we're ignoring the fact that filtering has real costs, as well. Filtering doesn't prevent the spam from traversing the internet, and furthermore it requires human time to update as the spammers change their tactics.

      You're right, but for the wrong (IMO) reason. Spam has economic incentive because all the costs of email are borne by the recipient. Botnets have made it even cheaper. You must remove that if you want to really fix the problem.

      If you do not remove the economic incentive, nothing will work because it will just be an arms race and the "good guys" will necessarily always be on the defensive side.

    As email asymptotically reachs 100% spam, we will have essentially created a mechanism whose sole goal is to deliver us undesired ads and scams. Talking about spam detectors and blockers and blacklists is irrelevant. Why devote all of this energy to ensure that maybe 5, 10, or 20 people can contact you or your business a day? Or even 20,000, which only highlights the issue that separating spam from valid emails is just bad juju. Simply put, there is no solution to asynchronous communication that is not too tedious or too restrictive. We'd be a lot better off if we blew up all the email servers, and put all of the energy and cost savings into developing encrypted telepathy. You think I'm kidding.

I could probably reduce it to zero with a bayesian filter, but I won't bother. Scanning through my logs, my server rejects literally thousands of spams every day, and I'm just one guy with two email addresses and a handful of aliases.

    So, it would come as no surprise to me that spam volume is that high, I just never see it. I almost want to turn off my filter for a day just to see what would happen.

    Well, maybe not. :)

      I knew somebody would bring up greylisting. :) During the business day[1], I work for a company that produces several widely-used anti-spam appliances and a service-based filter as well. We see about 2,000 networks a week, and get a pretty good feel for spam trends and countermeasure effectiveness. I can say with all honesty that in my experiences, greylisting hurts more than it helps for most organizations.
       
      Basically, greylisting is putting an email transaction on hold to see if the sender will retry. The idea is that if the sender is illigitimate, they won't bother resending. However, spammers have been onto this method for as long as it's existed, much moreso lately. All they have to do is take greylisted hosts and move them to the end of their script for later processing. The second time around, the spam gets through anyway. Even with its meager benefits, most organizations want email to come through as quickly as possible, and greylisting delays email by its very nature. It's also much less effective than existing technology that won't hinder most legitimate mail like DNSBL and/or SPF, spamwords+OCR (for image spam), and blocking on unknown recipients.
       
        To summate, if greylisting makes you happy, then don't let me dissuade you from using it. it does indeed stop some spam. But please don't give the false impression that it's a magic bullet; most of the complaints we receive are from clients who've enabled greylisting and can't figure out why their mail is delayed.

      [1] I am also a consultant to another firm who hosts manged email with spam filtering. Due to the complaints above, we have also disabled greylisting there. It was only effective at stopping about 5% of spam reliably, but a delay is put on all mail that isn't otherwise whitelisted. There are plenty of other methods which are both more effective and don't slow down the mailflow or tie up much resources on the MTA.

        I think you miss the true point of greylisting. See, the delay is only half of the whole equation. Sure, the host may try again, but I'm also subscribed to a few relatively non-strict DNSBL lists. Now, imagine the combination:
        1. Spammer sends a spam.
        2. Spam gets delayed by 5 minutes.
        3. Lazy Spammer neglects to resend. EOM.
        4. Spammer gets put into a DNSBL sometime during the day.
        5. Creative Spammer resends several hours later.
        6. Rejected as bad host, due to DNSBL.

        Also, postgrey, like most greylist p

  • Despite all the recent hoopla about Russian criminal gangs the article makes it clear that the US leads the world in zombied boxes.

    My point is not that Americans are evil, but rather than we need to look a lot closer to home in tackling these problems rather than looking for some grand criminal conspiracy to crack.

    The conspiracy may exist but if local ISPs simply refused to route packets from zombied boxes then their owners would soon work out they had to do something.
  • I think there's more to the spam problem then the usual people we blame for it.

    I have a personal email address on my own domain that used to NEVER get spam. I moved into my own apartment a month ago and I signed up a new phone number with Bell Canada and a new account with my local city utility company. I gave that email address to both without thinking- usually I give one of my alternates. Well, now that address is getting tons of spam of the worst kind.

    So, either Bell or my local utility sold my address.
  • I keep seeing statements, including one in the PDF report from TFA, that Win+IE users can get their machines infected with malware just by visiting a web site, without even clicking their mouse on anything in the site. However, these statements always seem to come from people who make money in the security business, and they never seem to say anything about what the actual IE vulnerabilities are. I'm very skeptical, although I haven't run Windows in a decade, so maybe I'm just naive. Can any slashdotters wi
