Patch_Tuesday

by hoover Reverse Engineering beginner New to reverse engineering? This beginner challenge is an introduction to dynamic debugging and patching Windows programs.

The provided x86-64 .exe promises a free flag, but it does not behave the way we want. Open it in a debugger such as x64dbg or IDA Free, run it, and step through the code that decides whether you receive the flag. Watch how the program compares values and follows a conditional jump.

Try changing that jump while debugging, or patch the instruction in the executable and run your modified file again. Your goal is to make the program follow the path that produces the expected behavior.
