Embodiments include identifying, at a logical path node, a first logical path and a second logical path; executing, by a processor implemented at least partially in hardware, a first set of instructions to follow the first logical path; storing, in a memory, a first set of information obtained from following the first logical path; evaluating, by a malware handler module implemented at least partially in hardware, the first set of information for malware; restoring, from the memory, environmental data for the first logical path node; executing, by the processor, a second set of instructions to follow the second logical path; storing, in a memory, a second set of information obtained from following the second logical path; and evaluating, by the malware handler module, the second set of information for malware.

Executing full logical paths for malware detection

Embodiments are directed to hooking a call for a malware monitoring logic into a JavaScript API engine interpreter. Upon JavaScript being placed into heap memory, the malware monitoring logic can initiate an evaluation or analysis of the heap spray to determine whether the JavaScript includes malware or other malicious agents prior to execution of the JavaScript shell code. Upon execution of the JavaScript within the sandbox, the malware monitoring logic can initiate monitoring of the JavaScript using malware analysis and/or execution profiling techniques. Inferences can be made of the presence of malware based on a start and end time of the JavaScript execution.
