What cruelsister is demonstrating is that "true" zero-day malware, no antivirus, antimalware products will be able to stop it, as they are unable to recognise the malware, a bit like an infection you catch/develop the immune system (at first) cannot recognise the pathogens, that's why the HIV virus is so affective. You need layered security. Cruelsister is very intelligent, what would providing a few samples achieve, when new ones are emerging on a hourly basis? It's demonstrating that the current threat envelope can, and will beat all antivirus software, even at enterprise level.
