Abstract: According to one embodiment, a system of detecting malware in a specimen of computer content or network traffic comprises a processor and a memory. The memory includes a first analysis logic and a second analysis logic that may be executed by the processor. Upon execution, the first analysis logic performs a static analysis in accordance with an analysis plan to identify one or more suspicious indicators associated with malware and one or more characteristics related to processing of the specimen. The second analysis logic performs a second analysis in accordance with the analysis plan by processing of the specimen in a virtual machine and monitoring for one or more unexpected behaviors during virtual processing of the specimen in the virtual machine. The analysis plan may be altered based on the results of one of the analyzes.

Abstract: Techniques for malware detection are described. Herein, a system, which detects malware in a received specimen, comprises a processor and a memory. Communicatively coupled to the processor, the memory comprises a controller that controls analysis of the specimen for malware in accordance with an analysis plan. The memory further comprises (a) a static analysis module that performs at least a first static analysis to identify a suspicious indicator of malware and at least partially determine that the specimen includes a packed object; (b) an emulation analysis module that emulates operations associated with processing of the specimen by a software application or library, including unpacking an object of the specimen when the specimen is determined by the static analysis module to include the packed object, and monitors one or more behaviors of the specimen during the emulated operations; and a classifier that determines whether the specimen should be classified as malicious.
