About the Sourceforge part:
Those kind of hack softwares, even if intended for script-kiddies are whatnot, are "masked" into security software. If you look at the description of the program on Sourceforge you can see it says "For network security testing. ". AKA they "suppose" it was made to be testing on your own server, to stress it. But that's obviously a lie, but the admins on Sourceforge can't blame the devs, who said "clearly" it's just for security testing.
