So, we have a PE executable here. Let's first execute it and see what we got:   ![HappyBossFight_intro.png](images/HappyBossFight_intro.png)
If we try to hit our dear Happax, here's what we have:   ![HappyBossFight_test_hit.png](images/HappyBossFight_test_hit.png)
We hit him with 654 damage. Remember well this number, it will be useful in a few minutes.
After dealing with our damage, the cat kill us and the program stop.
Quick review of the other options:- 2. Stats: give us our stats, not very useful though.- 3. Switch weapon: add a few damages to our weapon, it can maybe be used to up our damages until we can one shot Happax (but I'm lazy).- 4. Flee: quit the program.
Let's have a basic check of the reversed binary's main function:   ![HappyBossFight_reverse.png](images/HappyBossFight_reverse.png)
Without even trying to understand the program, we can see space in memory (var_1bh) set to the value of our damage:   ![HappyBossFight_damage.png](images/HappyBossFight_damage.png)
We try to modify this value to something greater to check if there is any modification protection in the program:   ![HappyBossFight_modify.png](images/HappyBossFight_modify.png)
Let's see what we get now:   ![HappyBossFight_win.png](images/HappyBossFight_win.png)
Here is the flag!
