I've tried to understand and mod the open source obfuscator ConfuserEx but never got the result I was anticipating. (All the unpackers unpacked them with ease no matter what I added/changed 🙄). So I shifted my attention towards the commercial obfuscators and oh boy the pricing on these.... I've tried NetGuard, Babel, NetReactor,.. and so on. On some of these there were still vir…

    VirtualGuard v1.0 This file is protected by the first version of VirtualGuard.

Haven't seen it anywhere else. Let the record state this is not a "mod" of any other vm, so if you are interested in seeing some new stuff this is for you. This sample contains some fairly simple branch offset mutations, at first glance it may be a slight "wtf moment" (at least I hope), but as soon as you figure out how the compa…
