‫ McAfee Threats Report: Second Quarter 2013-2st Section

Date: 2013-09-09
The McAfee Labs has studied the security threats of the second quarter of 2013 in a report. The following report is briefing that report.
Messaging Threats

In April, spam volume surpassed 2 trillion messages, the highest figure since December 2010. A slight decline in May and June still left the count higher than any time since May 2011.

Botnet breakdowns

Infections from messaging botnets, which supply spam worldwide, have showed an overall decline since May 2012, but this quarter’s trend was again upward.

Cutwail remains in first place among botnets, causing more than 6 million new infections during the quarter. Kelihos was a distant second, at 2.3 million.


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 June’s end, the total number of suspect URLs tallied by McAfee Labs overtook 74.7 million, which represents a 16 percent increase over the first quarter. These URLs refer to 29 million domain names, up 5 percent from the previous period.


This quarter, we recorded per month an average of 3.5 million new suspect URLs related to about 430,000 domains.

Most of these suspicious URLs (96 percent) host malware, exploits, or codes that have been designed specifically to compromise computers. Phishing and spam represent 2.1 percent and 0.3 percent, respectively.
