The Internet threat landscape is constantly evolving as new risks emerge and attackers leverage new tools. Intel Security’s McAfee Labs published its February 2015 Threats Report on Feb. 24, providing an updated status on the threat landscape. Among the key trends identified by McAfee Labs is the continued misconfiguration of Secure Sockets Layer (SSL) encryption for mobile apps. Also, the overall volume of mobile malware continued to grow throughout 2014, topping 6 million samples in the fourth quarter. While mobile malware is a growing concern, it’s still only a small percentage of the total volume of malware samples, which now stands at 350 million. McAfee Labs’ report also calls out a specific class of software identified as potentially unwanted programs (PUPs) that are often adware and could endanger user privacy. McAfee Labs noted that it sees PUPs on more than 91 million systems in a typical 24-hour period. PUPs aren’t the only type of bad software fishing to get onto end users’ systems, however. Angler was the leading exploit kit in use in 2014, deploying multiple types of malicious payloads that infect users, according to the report. In this slide show, eWEEK examines key takeaways from the McAfee Labs report.
