Dynamic Code Instrumentation

Applications are implemented with functions.

• Functions have addresses that may be determined, or subverted.

• Java uses further abstractions when using native code.

  • Creating strict interactions points towards which is possible to access the external world.

This enables the possibility of manipulating symbols/ addresses to instrumentalize code.

• Observe the internal structure of the program flow.

• Inject new code by replacing the implementation of a function represented by a symbol.
