Nothing fancy for the app, is a concept to those builders people use in Malware/Server Generators, The Stub is currently missing but you can use literally anything as the Stub xD Just pick any executable, copy it to the builder directory and rename the file to "Stub.exe" it should work as expected. Simple DeObfuscateMe - AznObfuscator Custom (ConfuserEx) For me it's very difficult to deob, If you can do this, then you are all f!@# gods xD Tried everything: Dumping -> Leaves Crashing app, Tried Fixing it, Failed... Used CC tools, None worked. Using UnConfuserEx Seems to work, but leaves app crashing -> Tried Fixing and still crashes... …

Updated 30/6 Inspired by HellSpider's topic i upload a simple unvirtualizeme protected with latest licensed Oreans Code Virtualizer, for research purposes. It supports 4 types of VMs, each can be "white" , "red" or "black" (small, bigger, biggest). Pressing buttons 1-4 will pop up 2 messageboxes.

Protect : Confuser + Dotfuscator + BOX Welcome challenge! unpackme.rar

Hello everybody! Today I would like to present you all an unpackme protected with the latest version of SoftwarePassport/Armadillo. This one is one of the most complete Armadillo unpackmes ever made, implementing almost everything Arma puts in the hands of the user ranging from the simple "Protect with password" to the nanomites, the code splices and everything in between. I have tried not to make it too easy for you all, just take a look at it The final goal is to manually unpack it, study it and show you have been able to read the first file you see when opening the password protected archive attached to this post (Mistery.7z). Enjoy! Unpackme.7z Mi…

Here is a KeygenMe written by a friend, He requested i should upload this as a challenge here. Here is it KEYGENME.rar

hey guys, as some of you may already know, I've been working on an obfuscator for quite a long time. https://www.disguiser.net/ There is still a lot of stuff to improve, but I' like to know, how long it takes an experienced reverser to code a Keygen for this. All features are present in normal mode, so I still have something harder in case this is too easy for you guys I'd rate it 6/10, let me know what you think PS. it might not be the best nor innovative, but its mine! if you find my hidden messages, you will get something from me (yeah, plural! and PM me for your small gift, once you found them) greetz li0nsar3c00l [RTN] Keygen…

Very simple modded version, nothing special. CrackTest_.rar

This is a simple UnpackMe using VMProtect Ultimate v2.13.5. I also used vmp's licensing system in this UnackMe, and locked one function with key. I have provided 3 different keys for this bin. A blocked key ,a valid key locked with a hwid(which i suppose no one has th same hwid) and an expire key. I also added 2 anti-debug thread to this file. Using VMProtectIsDebuggerPresent(if you have sod, i guess you can bypass this one pretty easy) and VMProtectIsValidImageCRC(crc). Didn't use VMProtectDecryptString feature. Several things I expect from this UM: Simply unpack it. Bypass the blacklist key. Bypass the expired situation. Patch hwid. Better create a …
