Hi Sithum!
Yeah! you can modify more rows, just be careful to don’t break the code, that’s why we try it first whithout defender or AVs enabled. Once we know the backdoor works we can try to modify it, turn on AV again and if it pass we know we should get a connection back, but this is a matter of try and error.
Hope it helps!

Hi Sithum!
Just follow Zaid’s suggestions about what can be actual code and what can be modified. Then search around your code with the hex editor tool.
