“Malware continues to change at a rapid pace, as evidenced by new types of high-tech, military-grade malicious code grabbing headlines such as Stuxnet, Duqu and Flame.
Another category raising its ugly head is the malware developed specifically for industrial espionage, like ACAD/Medre.A, which we will be seeing more and more of in the future. Why these sudden spikes in the news? This isn’t something new; these kinds of situations have happened before. But since people in general are becoming more security-aware due to the ongoing stream of information and related coverage in the media about state-sponsored malware, these anomalies are now noticed on a more regular basis and as a result of being detected more often.”
