Question

How can the nature of the values stored inside registers be identified during reversing?

a.

By detecting cases where a register is used simply to allow instructions access to specific values

b.

By observing the same register being repeatedly used and updated throughout a single function

c.

By analyzing the assembly language code and identifying the source of each value

d.

By checking the contents of each register using a debugger

Posted under Reverse Engineering

Answer: (b).By observing the same register being repeatedly used and updated throughout a single function Explanation:If the same register is repeatedly used and updated throughout a single function, it is often an indication that the register is being used for storing a local variable defined in the source code.
