The seemingly relentless growth of malware has not abated in 2015, though there are some reasons to be optimistic, according to the latest security statistics from Intel Security. Intel Security’s McAfee Labs released its August 2015 Threats Report on Sept. 1, detailing the state of the threat landscape during the second quarter of 2015. Among the trends noted in the report is the fact that ransomware attacks continue to accelerate, a trend that McAfee also reported in the first quarter of 2015. For the second quarter, McAfee Labs reported a 58 percent quarterly gain in the number of new ransomware samples it detected. Another continuing trend is the growth of mobile malware, which grew by 12 percent in the second quarter over the first quarter. Mobile malware attacks, however, are not uniform geographically, with infection rates statistically higher in Africa and Asia than in North America and Europe. On a more positive front, as was the case in the first quarter, McAfee Labs is reporting yet another quarterly decline in the volume of global spam, marking the third consecutive quarter of decline. In this slide show, eWEEK examines key takeaways from the August 2015 McAfee Labs Threats Report.
