Abstract:
A malware detection system configured to detect suspiciousness in obfuscated content. A multi-stage static detection logic is utilized to detect obfuscation, make the obfuscated content accessible, identify suspiciousness in the accessible content and filter non-suspicious non-obfuscated content from further analysis. The multi-stage static detection logic includes a controller, a de-constructor, and a post-processor. The controller is configured to receive content while the de-constructor configured to receive content from the controller and deconstruct the content using the analysis technique selected by the controller. The post-processor is configured to receive the de-constructed content from the de-constructor, determine whether a specimen within the de-constructed content is suspicious, and remove non-suspicious content from further analysis.
