China Cleans Up Spam Problem 69

angry tapir writes "It's been a few years coming, but it looks like China may finally be getting a handle on its spam problem. Once the largest source of the world's spam, China has been gradually fading off the list of the world's top spam-producers. Right now Cisco Systems' IronPort group ranks it at number 18 in terms of spam-producing countries. That's a big drop from two years ago, when it consistently ranked in the top five."

      It also helps if you have the sort of government where you can just summarily execute anyone suspected of spamming.
      Everybody can get on board with that, right?

  • I feel like a old slashdot article from last year (yes somehow that's old) claimed that most spam came from the states. I couldn't find the article but I did find this after googling it: http://www.infoniac.com/hi-tech/most-of-spam-comes-from-the-usa-says-sophoslabs.html [infoniac.com]
    • From the article:

      ...the U.S. remains the top-spamming country and the source of about one-fifth of the world's spam.

      Note that "one-fifth". Lots of bots here but more in the rest of the world. They are managed mostly from Russia, of course.

      And that article was a dupe from the 2001 when everyone started blocking mail from Korea because it was mostly spam. The US was the origin of the first spam, and has constantly been the biggest producer of spam since then, no matter what people's perceptions are. Currently Turkey seems to be on the up, but you can bet that it is still well behind the US.

        The US is also the origin of the first non-spam email, and has constantly been the biggest producer of non-spam emails. Simple fact of the matter is, the US has the most computers, and the most infected computers.

          According to the (slightly out-of-date) article, the whole of Europe sends less spam than the US. I'm quite sure there are more computers in Europe than in the US, as the population is more than 60% larger (only counting EU. The spam level in the article is likely about the whole continent, which has about 130% the population of the US), and the developement level is similar.

      • I have been firewalling China (the whole world, actually, except North American/ARIN registrants) for years on my company's servers. That alone cuts our spam load by 75-80 percent. RBLs and other measures take care of most of the rest, and server logs indicate less than 3 percent of spam gets through. That seems to be the equilibrium point between blocking spam and false positives.

    • It's really annoying. ISPs like Comcast forbid you from running any types of servers in the TOS, but don't even bother to block outbound port 25 connections. It's the worst of both worlds; legitimate server operators are banned, but they won't raise a finger to stop botnet spamming originating on their networks.

      All they would have to to do is block port 25 by default, and say "call us" if you need to run a server. Spam would drop drop dramatically, and home servers would be possible.

      • by heypete ( 60671 )

        Are you sure they don't block outbound port 25? Searching for "comcast port 25 blocking" seems to suggest that they are, in fact doing so, and have been since 2004.

        Cox, one of Comcast's major competitors, also blocks port 25 on residential lines. Naturally, connections to port 587 go through without any problems. They also block inbound port 25 and port 80, which prevent people from running a home mail or web server, even if they use Cox's "smarthost" outbound mail server.

          When I was with Comcast in 2009, I had no problems sending outbound data on port 25. I had a lot of mail dropped/bounced either because my IP block in a blacklist, which is common for a residential IP, or because I couldn't ask Comcast to create a correct reverse DNS PTR record for me. However, there was nothing on Comcast's side that was blocking traffic.

          • They've been blocking port 25 in problem areas since 2004; AFAIK, they only block when they've got a reported problem (by their definition).

    China has more Internet users [internetworldstats.com] than any other nation (420 million), so being down at number 18 for spam seems quite good.
    • I think that the number of hosts vulnerable to being turned into bots is what matters, not the number of users. A large fraction (maybe a majority) of China's users work from internet cafe so there are likely to be many users per host.

      • Now, if Google were to lose a bunch of accounts and Nigeria were to simultaneously clean up its spam problem, I'd be less likely to call coincidence :p

        Google alone among the major free email providers does not include x-orginating-ip info (unless you send through gmail over smtp, in which case they do, for some reason), which makes filtering more expensive for people who see no reason to accept any email from 41/8 or other netblocks allocated to Africa. Gmail: a 419ers best friend.

  • Most spam is sent out by botnets anyways, which of course have compromised PCs from all over the world contributing to them. China cleaned up a few (million) boxes, but other 2nd and 3rd world countries have been coming online in larger numbers to make up for the loss.

    In the end, its all for naught, however. As long as the spammers can make money sending out spam, they will find a way to do it. We can play international whac-a-mole with security and filtering settings but the spammers will continue to

      The last three are all 1.3% because of rounding, but the order really is China - Vietnam - Poland.

  • OK, not to cast this accomplishment in a bad light; but I wish rankings weren't used so often for this kind of thing.

    The trouble with ranks is that everybody could be really close to the same number, and the rankings are just statistical noise.

    Somebody else posted the percentage list upon which the rankings are based. That's better, but you still have to consider the number of hosts. A country with a small number of hosts could rank really low, and still have a large percentage of spambots.

If the message is displayed in chinese, the mailer knows it's in chinese, so it COULD delete it instead. What's the setting for that ?!?

BTW, I noticed that the Chinese are a little on the lite side, weight-wise, when compared to our corn-fed-beef-fed Americans. There may be more of them, but as a whole we probably outweigh them.

      I set up a script that runs an uncloaked nmap whenever the attempted ssh logons from a single IP hits a threshold; the attempts from India and Brazil just keep on pounding away until they're done, but the ones from China stop within 10 seconds of the start of my nmap probe.

  • Too bad in China, "spam" worthy of blocking not only includes "want to get cheap pills / anatomical improvements?" emails, but also "want to go protest government policy?" emails.
