A security analyst wants to intercept function calls in a smartphone game as it runs and read memory values while keeping the application functional. Which option best supports dynamic instrumentation for these objectives?
Use Frida to inject scripts and observe memory references in real time
Disable all device restrictions and review files through a root-level browser
Recompile the game’s source to include a custom debugging module
Acquire a forensic snapshot and review data for suspicious files
The solution involving an injection mechanism that runs scripts in real time provides a way to intercept calls and examine memory details within an active process. Modifying source code or analyzing offline does not permit real-time observation of function calls. Fully bypassing device permissions may not reliably capture every function call without deeper instrumentation. A runtime code injection approach offers a flexible method for detailed inspection of function parameters and memory usage.
