‫ McAfee Threats Report: First Quarter 2013-1st Section

Date: 2013-06-10
The McAfee Labs has studied the security threats of the first quarter of 2013 in a report. The following report is briefing that report.
Mobile Malware

At the end of this quarter, the total number of samples in our mobile malware “zoo” reached 50,926, with 28 percent of that arriving in 2013. In all of 2011 we gathered only 792 samples. The growth of mobile malware declined slightly this quarter, but we’re still on course for another eye-catching—and record—year.

Although the threats of commercial spyware and adware are declining, we see that malicious spyware and targeted attacks are becoming more prominent. Malicious spyware combined with botnets are among the latest threats.

General Malware Threats

Malware shows no sign of changing its steady growth, which has risen steeply during the last two quarters. At the end of this quarter we now have more than 128 million samples in our malware “zoo.”

Rootkits, or stealth malware, are one of the nastiest classifications of malware we see. They are designed to evade detection and reside on a system for prolonged periods. After rising during most of the past year, growth in new rootkit samples has been flat for two quarters. All three of the rootkits types we track in this report matched this trend.

AutoRun malware, which often hides on USB drives and can allow an attacker to take control of a system, has risen rapidly for two quarters and reached a new high, with almost 1.7 million new threats. The number of fake antimalware products—which can behave as a form of ransomware, extorting money from victims to “clean” their computers— declined from its record level at the end of last year, but the overall numbers remain high. With Koobface, which plagues Facebook users, we found almost three times as many samples this quarter compared with last quarter. That’s another record high point and double the size of the prior mark, set in the fourth quarter of 2009. Password-stealing Trojans, which attempt to raid victims’ bank accounts, were flat in growth yet also established a new record.
