Abstract
Mechanisms for injecting code into embedded devices are provided. In some embodiments, once the code is injected into the embedded device, the injected code can analyze and modify the code of the embedded device (e.g., firmware) to create the execution environment for the injected code. For example, the injected code can identify program instruction locations in the code of the embedded device into which jump instructions can be placed. The injected code can also insert at least one jump instruction at an identified program instruction location in the code of the embedded device. In response to the execution of a jump instruction, the injected code can save a context of the code of the embedded device to memory and loading a payload context into a processor of the embedded device. The payload context can then be executed by the processor of the embedded device.
