Symantec today announced the findings of its January Symantec.cloud Intelligence Report, which shows that spammers are using holidays and major events to make their mail more appealing.

Symantec Intelligence has seen more than 10 000 unique domain names compromised with a redirect script written in PHP that contains a reference to the New Year in the file name. These redirect scripts were hosted on compromised Web sites and links to these were included in spam e-mails, which were subsequently blocked by Symantec.cloud.

To further entice recipients to open their messages, spammers used additional social engineering techniques by including parameters in the URL to suggest that the destination is a social networking site.

Symantec Intelligence expects to see spammers taking advantage of other “calendar events” like the Chinese New Year celebrations, which ended on the night of 4 February, and Valentine's Day, which was on 14 February.

“We also expect to see plenty of spam and malware taking advantage of some of the major upcoming sporting events this year. We are already seeing references to the Summer Olympics in London (27 July to 12 August) as part of 419 or advance fee fraud messages,” said Mark Smissen, Business Development Manager, Symantec.cloud.

“By relating their mails to widely-celebrated holidays and current events with global interest, spammers and malware authors can (at first glance, at least) make their messages more interesting, and increase the chance of recipients visiting spam Web sites or becoming infected,” Smissen said.

During December, global spam levels dropped, but in January gradually returned to similar levels as in November 2011, which is still lower than the 2011 average. There was an overall decrease in phishing numbers globally and January saw South Africa finally dropping out of the top five countries.

January 2012 highlights:

Spam: The global ratio of spam rose by 1.3% since December, bringing it to 69.0% (one in 1.45 e-mails). This follows a noticeable drop in December, when spam fell to 67.7%. The recent increase means spam has almost returned to the same level as in November 2011.

Spam accounted for 69.5% of e-mail traffic in South Africa.

Phishing: The global phishing rate increased by 0.06 percentage points, taking the average to one in 370.0 e-mails that comprised some form of phishing attack.

E-mail-borne threats: The global ratio of e-mail-borne viruses was one in 295.0 e-mails, a decrease of 0.02 percentage points since December 2011. Twenty-nine percent of e-mail-borne malware contained links to malicious Web sites, unchanged since December 2011.

In South Africa, one in 305.9 e-mails was blocked as malicious.

Web-based malware threats: January saw an average of 2 102 Web sites each day harbouring malware and other potentially unwanted programs including spyware and adware; a decrease of 77.4% since December 2011.

Endpoint threats: The most frequently blocked malware for January was WS.Trojan.H. WS.Trojan.H is generic cloud-based heuristic detection for files that posses characteristics of an as yet unclassified threat. Files detected by this heuristic are deemed by Symantec to pose a risk to users and are therefore blocked from accessing the computer.
