The McAfee Labs has studied the security threats of the first quarter of 2012 in a report. The following report is briefing that report.

Messaging Threats

We saw spam levels reach record lows at the end of 2011. Although another spike occurred in January, by the end of the quarter spam levels had again fallen to the lows of the previous period. In the last three months, we observed increases in China, Germany, Poland, Spain, and the United Kingdom; but volumes in Brazil, Indonesia, and Russia declined. Despite global levels dropping, spearphishing and spam are as dangerous as ever; consumers and businesses must remain vigilant. The sophistication of today’s threats remains high.


 

Botnet Breakdowns

Overall messaging botnet growth jumped up sharply from last quarter. Infections rose in Colombia, Japan, Poland, Spain, and the United States. Indonesia, Portugal, and South Korea continued to decline.


 

Many of the leading messaging botnets this quarter showed flat growth or a decline in new infections— with the exception of Cutwail, which increased significantly.


 

Web Threats

Websites can gain bad or malicious reputations for a variety of reasons. Reputations can be based on full domains and any number of subdomains, as well as on a single IP address or even a specific URL.

Malicious reputations are influenced by the hosting of malware, potentially unwanted programs, or phishing sites. Often we observe combinations of questionable code and functionality. These are several of the factors that contribute to our rating of a site’s reputation.

Last quarter McAfee Labs recorded an average of 9,300 new bad sites per day. Including spam email URLs, this figure reached 11,000 hits per day. During this period, however, the latter figure dropped to 9,000 hits per day.


 

The number of websites hosting malicious downloads or browser exploits is still increasing.


 

The number of websites delivering malware and potentially unwanted programs dropped by about athird this quarter, with an average of around 4,200 new sites per day, compared with about 6,500 per day during the fourth quarter of 2011.


Phishing sites were unchanged from last quarter. We again identified an average of approximately 2,200 new phishing URLs per day this quarter.
