Eclipse Runtime Obfuscator Hey everyone, I’m sharing an UnpackMe challenge that combines VMProtect packing with runtime function obfuscation using Eclipse Runtime Obfuscator. This should be an interesting challenge for those who enjoy working with dynamic obfuscation and anti-debugging techniques. Protection Details: VMProtect is used for basic packing, with import protection and anti-debug enabled. Eclipse Runtime Obfuscator dynamically obfuscates function execution, making dumped analysis and debugging difficult. Function code is relocated to a new memory region at runtime and accessed through vectored exception handling (VEH) instead of…

Difficulty : 7 (I think) Language : .NET Platform : Windows OS Version : Windows 7 and up Packer / Protector : eazFuscator 2018.2 Description : Hello, here I am again 👋. After last and first attempt in the KeygenMe-Section, I tried to put more attention on packing my code harder. 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. VirtualGuard is an obfuscator I develop that I am trying to receive some stress testing on I hope this VM makes people think at least a little bit; It's fairly close to 1:1, however I do believe I do some interesting things with comparisons and branching. 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…
