Malicious Spam Jumps To 3B Messages Per Day 211

Posted by kdawson from the with-a-b dept.
Trailrunner7 writes "Last year saw a monstrous increase in the volume of malicious spam, according to a new report (PDF). In the second half of 2009, the number of spam messages sent per day skyrocketed from 600 million to three billion, according to new research. For some time now, spam has been accounting for 90 or more percent of all email messages. But the volume of spam had been relatively steady in the last couple of years. Now, the emergence of several large-scale botnets, including Zeus and Koobface, has led to an enormous spike in the volume of spam."

      I see about the same amount. Some times it goes months with no spam then I get two or three in a week. I reckon the spammers are constantly adjusting their techniques to try to get through the filters.

      Hear, hear. I was very surprised when I recently checked my spam volume. That is, in my Gmail *spam* box, not inbox. The inbox is usually clear of it, but the surprising part was that I had around a third to a fourth of my former spam volume a few years ago! I used to have to have 1.5 pages of spam per day before, now you have around 0.5 pages of daily spam in the spambox.

        That's it. Most spam is rejected without telling you about it, possibly even before it gets delivered to the mail server. The spam folder gets the questionable stuff.

      • I like Gmail for many reasons, one of which is their awesome spam filter. I get only one or two mis-categorised email every couple of weeks, the rest goes to the spam box. Couple that with the coloured labels & filters, and spam/not spam is very easy to identify.

        Hotmail on the other hand is terrible. Ages ago when I was using Hotmail, I ended up with the majority of my inbox being spam so I gave up and tried Gmail. I don't know how good Hotmail is at the moment (or others like YahooMail).

      I do agree that gmail's spam filter does not let much through, in truth, it is way too aggressive. Are you subscribed to mailing lists? Often it'll just tag some random message as spam. I've had various things end up in spam over the years, and really wonder how many landed in there that I never noticed (who checks their spam folder every couple of days?).

      SPAM was the absolute bane of my existence (I have several very public email addresses that have to remain that way) until the day I finally (at at the time reluctantly) decided to run all of my mail through Gmail accounts, without exception. I had used block lists, several ISP-based filters, spamassassin post-POP3 on my own local net, and a bunch of filters, and it was eating hours a day of attending to SPAM (new filters, fixing filters, marking as spam, marking as ham) and so many CPU cycles that a dedicated box couldn't keep up. Not to mention that due to the processing overhead of all that filtering, when someone did send me a message and told me so, I'd have to tell them "I'll get it in ten to fifteen minutes." And all for a few (three, really) email queues that belong to one person and a couple assistants?

      Now I forget that SPAM exists, and my email comes in more or less instantly.

      For a decade now, Google has more or less singlehandedly kept the internet usable.

Other users help train the spam filter for you before they get to your inbox. The orbs blacklist can be kept up-to-date more quickly on a managed host.

          That's why its best to use the middle way. Have own domain and some way to quickly create a new address on it (even if they all go to same mailbox). Always use a new address for different sites and purposes. That way if one of them starts to get problems with spam, you know who sold your address and can easily disable it.

      Two problems with this idea. First, the people who actually buy stuff from spam can be difficult to identify. I think many of them know deep down that they are doing something exquisitely stupid and will deny it if asked. Second, even if we can identify these spam patrons, it is quite illegal in most places to bash their empty skulls in with a baseball bat. Barring some significant changes in legislation, I just don't see how the problem can be tackled from this end.
