Welcome to HBH! If you had an account on hellboundhacker.org you will need to reset your password using the Lost Password system before you will be able to login.
Basic 11
I couldn't do this, either (granted, I haven't tried much). I know that variables are sent such as the user agent which we saw in an earlier mission, and I know that your OS variable is sent. However, I have not been able to find an "OS changer" of sorts.
I tried using the old user agent switcher to change the variable (in my case) Win32 to HellboundHackersOS, but this didn't work.
How would one change the OS variable sent to websites?
