Kaspersky Lab has published its spam report for December 2011, which shows that the last month of the year was predictably quiet – compared to November – with the share of spam in email traffic falling by 4.4 per cent and averaging 76.2 per cent for the month.

The lull in business in the run-up to the holidays meant that botnets were crippled by empty offices and silent computers. While many spammers appeared to take a break for the festive season, the approach of Christmas didn’t prevent some of them from coming up with new tactics to attract users to their mass mailings. One of the favourite ploys was the use of coupon services to boost demand for products that were widely advertised in spam.

“We have not yet detected any malicious attachments disguised as coupons, although we expect that these will show up in spam sooner or later,” warns Maria Namestnikova, Senior Spam Analyst at Kaspersky Lab. “Anything and everything that is in demand on the Internet is eventually added to the spammers' arsenals in one way or another. New approaches are typically used by the participants of affiliate programs that send out spam advertising medications and replicas of luxury goods. They are later joined by distributors of malicious code.”

Malicious files were detected in 4 per cent of all email traffic in December, which was an increase of 1 per cent, compared to November’s figure. A third of all Kaspersky Lab email anti-virus detections were for mail emanating from Russia and the US. The malicious program most frequently detected remains Trojan-Spy.HTML.Fraud.gen (11 per cent) – a Trojan designed to look like a registration web page for a financial organisation or some other online service.

When it came to spam sources in December, India remained on top, accounting for 12.43 per centof all spam, followed by Indonesia, Brazil and Peru. Significant movers among this particular rating in December were South Korea, falling from second to fifth place, and the UK, which fell from seventh to seventeenth. Remarkably, the latter started the month as the eighth biggest source of spam but had fallen to 53rd by the final week of December.
