Python Patchme (Custom VM)
by svenskithesource- 5 replies
- 3.9k views
View File Python Patchme (Custom VM) Hello, Since the use of vm's is quite popular in .net obfuscation I thought it would be interesting to make one in Python. Hereby I release my first crackme using my VM. It's a very simple VM so it shouldn't be that hard to reverse with the right knowledge. This is purely experimental to see if it would be useful somehow. I also used my own protector that adds cflow, so expect to see a lot of jumps. Goal: Patch it (ultimately devirtualize it, but that's not necessary) Submitter svenskithesource Submitted …

View File Tricky Goals: Bronze - Patch the crackme to show the correct message Silver - Bronze + explain what is happening I don't know why Windows Defender is giving a false positive. My past here should prove I am not here to harm anyone. I only used Appfuscator for renaming. I checked the file and I did not see any other obfuscation or anything annoying automatically inserted by Appfuscator (like outline method calls). Please extract all the files in a folder to make the exe work properly. Let's fight! Submitter LoLLo90 Submitted…

Poetic AutoIt (string/integer obfuscation)
by SimplyMercurial- 1 follower

View File Poetic AutoIt (string/integer obfuscation) This is a simple CrackMe consisting of an input. The correct input is two stanzas of a particular poem and will reveal a label of the poem title and author upon success. Otherwise, "Try again..." will be displayed. If I'm allowed to be picky, I'm primarily interested in scripted efforts to RegEx analyze strings/integers. Very little effort (as in none) went into hiding the correct string. The script was merely passed-through a self-made obfuscator. Full disclosure: It contains rudimentary debugger and compilation checks which, if failed, falls into a while loop with a one secon…

Language : C# Platform : Windows x32/x64 OS Version : Windows 10 Packer / Protector : Modded ConfuserEx + a packer. Description : Basically, just find the key to decode the string. All I will be (probably) using this for is for is to garbage-up some .INI files for my apps to read/write to, so that way there's no plain text. This isn't for hiding some sensitive information lol. Also, if you could, rate the difficulty from 1/10. Thanks! Screenshot : CrackMe.rar
