PMP, um dos componentes de DRM do Vista: crackeado

Pois é, não demorou. O cara não vai liberar o código ou oferecer mais detalhes por medo de represálias, mas se um consegue, outros conseguem também.

[quote=Alex Ionescu]The great thing about the code I’ve written is that it does NOT use test signing mode and it does NOT load an unsigned driver into the system. Therefore, to any A/V application running, the system seems totally safe — when in fact, it’s not. Now, because I’m still booting with a special flag, it’s possible for Microsoft to patch the PMP and have it report that this flag is set, thereby disabling premium content. However, beause I already have kernel-mode code running at this point, I can disable this flag in memory, and PMP will never know that it was enabled. Again, Microsoft could fight this by caching the value, or obfuscating it somewhere inside PMP’s kernel-mode code, but as long as it’s in kernel-mode, and I’ve got code in kernel-mode, I can patch it.

To continue this game, Microsoft could then use Patchguard on the obfuscated value…but that would only mean that I can simply disable Patchguard using the numerous methods that Skywing documented in his latest paper.

In the end, the only way that PMP is going to work is with a Hypervisor, and even that will probably fail.[/quote]
