McAfee Labs this week released the McAfee Threats Report: Second Quarter 2013, which found that Android-based malware achieved a 35% growth rate not seen since early 2012. The company said the rebound was marked by the continued proliferation of SMS-stealing banking malware, fraudulent dating and entertainment apps, weaponized legitimate apps, and malicious apps posing as useful tools.
McAfee Labs registered twice as many new ransomware samples in Q2 as in Q1, raising the 2013 ransomware count higher than the total found in all previous periods combined.
The second quarter also saw a 16% increase in suspicious URLs, a 50% increase in digitally-signed malware samples, and notable events in the cyber-attack and espionage areas, including multiple attacks on the global Bitcoin infrastructure and revelations around the Operation Troy network targeting U.S. and South Korean military assets.
McAfee Labs researchers identified a set of common mobile strategies employed by cybercriminals to extract money and confidential information from victims.
“The mobile cybercrime landscape is becoming more defined as cyber gangs determine which tactics are most effective and profitable,” said Vincent Weafer, senior vice president, McAfee Labs. “As in other mature areas of cybercrime, the profit motive of hacking bank accounts has eclipsed the technical challenges of bypassing digital trust.”
