With specifically designed modulation schemes, covert channels effectively disguise secret messages as noise. Physical layer covert channels exploit the characteristics of radio signals to convey secret messages while remaining inconspicuous within wireless channels.

Our experiments show that our approach can effectively detect running malicious code on an end user's host with a small overhead. For detection, we execute these slices to match our models against the runtime behavior of an unknown program. Then, we extract the program slices responsible for such information flows. Such models describe the information flows between the system calls essential to the malware's mission, and therefore, cannot be easily evaded by simple obfuscation or polymorphic techniques. Our approach first analyzes a malware program in a controlled environment to build a model that characterizes its behavior.

In this paper, we propose a novel malware detection approach that is both effective and efficient, and thus, can be used to replace or complement traditional antivirus software at the end host. Although promising, these approaches are unfortunately too slow to be used as real-time detectors on the end host, and they often require cumbersome virtual machine technology. In order to address the shortcomings of ineffectivemodels, several dynamic detection approaches have been proposed that aim to identify the behavior exhibited by a malware family. Also, detectors that check for the presence of a sequence of system calls exhibited by a malware instance are often evadable by system call reordering. These models concentrate on the features of a specific malware instance, and are often easily evadable by obfuscation or polymorphism. Unfortunately, current host-based detection approaches (i.e., anti-virus software) suffer from ineffective detection models. However, it is even more important to develop mitigation and detection techniques based on the insights gained from the analysis work.

Without doubt, it is important to collect and study malware found on the Internet. With the increasing significance of malware in Internet attacks, much research has concentrated on developing techniques to collect, study, and mitigate malicious code. That is, computers that are compromised with malware are often networked together to form botnets, and many attacks are launched using these malicious, attacker-controlled networks.

In fact, most Internet problems such as spam e-mails and denial of service attacks have malware as their underlying cause. Malware is one of the most serious security threats on the Internet today.
