January Virus and Spam Statistics: 2006 Starts with a Bang

Commtouch has announced spam and computer virus statistics for the month of January 2006.  The data is based on information continuously gathered by the Commtouch Detection Center, which analyzed more than 2 billion messages from over 130 countries during the month of January.  The numbers are indeed concerning: 19 new email-born significant virus attacks, of which a troubling 8 (42%) were graded “low intensity”, 7 (37%) “Medium Intensity” and 4 (21%) were massive attacks—a rare phenomenon for a single month.  One outbreak of specific interest, consisting of 7 variants, illustrates how viruses are growing in sophistication: the first variant was launched around December 25th as a low intensity virus, however with subsequently released variants the attack’s intensity grew into a massive outbreak towards the end of the month.

Computer virus statistics from the Commtouch Detection Center indicate that 40% of attacks during January met this profile. 

Also, there is a clear connection between the attack’s speed and its intensity—the faster attacks are the biggest ones: while the average distribution time of low intensity attacks is a “leisurely” 27 hours and medium-intensity attacks can take 17 hours, massive attacks take as little as 5.5 hours to spread in hundreds of millions of emails.

Based in part on a reliable third party lab test, Commtouch was able to compare detection times of 21 leading AV engines against 19 new viruses in January.

January spam statistics show that 43.18% of global spam is sent from US-based sources (down from approximately 50%).
