‫ McAfee Threats Report: Second Quarter 2013-1st Section

Date: 2013-09-04
The McAfee Labs has studied the security threats of the second quarter of 2013 in a report. The following report is briefing that report.
Mobile Threats

This quarter “backdoor” Trojans, which steal data without the victim’s knowledge, and malware that goes after banking login information have made up the largest portion of all new mobile malware families. Spyware has also been active, and malware authors continue to target activists. Halfway through 2013 we have already collected almost as many mobile malware samples as in all of 2012. This quarter we added more than 17,000 Android samples to our database.

General Malware Threats

Malware shows no sign of changing its steady growth, which has risen steeply during the last three quarters. At the end of this quarter we now have more than 147 million samples in our malware “zoo.”

Rootkits, or stealth malware, are designed to evade detection and reside on a system for prolonged periods. Growth in new rootkit samples has been on a downward trend since the middle of 2011. 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, doubled at the start of the year and increased slightly again this quarter. The number of fake AV products—which scare victims into believing their systems are infected—rose during 2012 to a record level but has declined during the last two quarters. Koobface, which plagues Facebook users, peaked in 2009-10 and has remained at low levels since early 2012. Passwordstealing Trojans, which attempt to raid victims’ bank accounts, established a record high last quarter; this quarter’s figure was almost as large.
