Spam insights from Project Honeypot

Project Honeypot just published a report of their experience in processing 1 billion spam messages.  Highlights for the impatient:

  • For the past 5 years, spam “bots have grown at a compound annual growth rate of more than 378%. In other words, the number of bots has nearly quadrupled ever year.”
  • The top 5 countries which host bots are: China (11.4%), Brazil (9.2%), United States (7.5%), Turkey (6.3%), and Germany (6.0%).
  • Top 5 countries with the best ratio of security professionals to spam sources: Finland, Canada, Belgium, Australia (yay!), and the Netherlands.
  • The corresponding bottom 5: China, Azerbaijan, South Korea, Colombia, and Macedonia.
  • Top Spam harvesting countries: United States, Spain, the Netherlands, United Arab Emirates, and Hong Kong.
  • Fraud is rising as a cause for spamming:

    On the other hand “Fraud” spammers — those committing phishing or so-called “419” advanced fee scams — tend to send to and discard harvested addresses almost immediately. The increased average speed of spammers appears to be mostly attributable to the rise in spam as a vehicle for fraud rather than an increasing efficiency among traditional product spammers.

    As an anecdote to reinforce this, on one site i administer, i set up a dedicated subdomain which was purely designed to catch spam.  I placed some addresses in that domain on a web page, and within 1 day they had been harvested and 1 spam had been sent to each email address.  No email to that subdomain has been seen since.
