Abstract
Methods, storage systems and computer program products implement embodiments of the present invention for protecting a computing device, which includes a processor and a memory and is coupled to a storage device storing a set of one or more files. In embodiments of the present invention, a call to a specified function for execution by the processor is detected, and a stack trace for the call to the specified function is generated in the memory. Upon detecting, in the stack trace, a stack frame including a return address referencing a shellcode region in the memory, wherein the shellcode region includes executable code that was not loaded from any given file on the storage device, then the referenced executable code is compared to a list of malicious shellcode. Finally, a preventive action is initiated upon detecting a match between the referenced executable code and one of malicious shellcodes in the list.
