‫ McAfee Threats Report: First Quarter 2013-2st Section

Date: 2013-06-23
The McAfee Labs has studied the security threats of the first quarter of 2013 in a report. The following report is briefing that report.
Messaging Threats

After a long decline, spam levels were stable in 2012 despite some small upticks in July and October. This quarter, however, we saw a big increase that reached a volume not matched since May 2011.

Botnet breakdowns

Infections from messaging botnets have showed an overall decline since May 2012. This quarter we saw a rise in January, followed by a drop to the same level as three months ago.

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 just a few of the factors that contribute to our rating of a site’s reputation.

At the end of March, the total number of suspect URLs tallied by McAfee Labs overtook 64.3 million, which represents a 12 percent increase over the fourth quarter. These URLs refer to 27.7 million domain names, up 6 percent from the previous period. In our databases, we classify these URLs and domains according to their risk ratings.


This quarter we recorded an average of 2.6 million new suspect URLs per month related to about 470,000 domains. These figures return to the levels we encountered in the second and third quarters of 2012.

Most of these suspicious URLs (94 percent) host malware, exploits, or code that have been designed specifically to compromise computers. Phishing and spam represent 2.5 percent and 1.8 percent,  respectively.
