๐Ÿ•ต๏ธ What is Skidfuscator?

Skidfuscator is a proof of concept obfuscation tool designed to take advantage of SSA form to optimize and obfuscate Java bytecode code flow. This is done via intra-procedural passes each designed to mingle the code in a shape where neither the time complexity neither the space complexity suffers from a great loss. To achieve the such, we have modeled a couple of well known tricks to add a significant strength to the obfuscation whilst at the same time retaining a stable enough execution time.

This project is not completed. This is a proof of concept I've been working on for a while. As far as I could tell, there are some serious flaws with parameter injection.

โœจ Features

Here are all the cool features I've been adding to Skidfuscator. It's a fun project hence don't expect too much from it. It's purpose is not to be commercial but to inspire some more clever approaches to code flow obfuscation, especially ones which make use of SSA and CFGs

Third Generation Flow

What is third generation flow obfuscation? Well, contrary to Zelix's second generation flow obfuscation, we use an even more complex system with private and public seeds. Here's how it works:

We currently are working on a variety of ways to approach this system using various lightweight obfuscation methods. Here are the current ones to date: Here are the features:

Feature Type Description Status
Flow GEN3 Flow (Community) Obfuscates methods using the GEN3 Obfuscation methodology โœ…
Bogus Jump Flow (Community) Invalid jump to some random generated code to prevent skidding โœ…
Bogus Exception Flow (Community) Invalid jump to some random generated exception โœ…
Mangled Jump Flow (Enterprise) Mutation to the jump condition to make it appear more complex than it actually is โŒ
Exception Jump Flow (Enterprise) Changes done to flow semantics by forcing an exception then handling all the code in the catch clause โŒ
Exception Return Flow (Enterprise) Throw an exception with the value and catch it as opposed to returning it (Very heavy) โŒ
Strong Opaque Predicate Flow (Community) Use heredity and method invocation to pass a predicate as opposed to declaring it at the beginning of the CFG โœ…
Method Inlining Flow (Enterprise) Inline uncommon methods which aren't too big โŒ
Method Outlining Flow (Enterprise) Outline some non-sensitive blocks โŒ
Loop Unrolling Flow (Enterprise) Rewrite some loops instructions into continuous segments if the loop limit can be pre-determined โŒ
Flattening Flow (Community) Use a dispatcher method to harden the semantics of some block ranges (do not use entire method) โš ๏ธ
String Encryption String Encrypt the strings using the opaque predicate โœ…
Reference Encryption Reference Encrypt the reference calls using InvokeDynamic using the opaque predicate โŒ
Reference Proxying Reference Proxy references using a builder pattern OR dispatcher classes (mostly for initialisation) โŒ

Todo

  • Converting block creation to a factory style to give us more leniency to play around with stmts and stuff without having to wrap em
  • Convert method nodes and modasm to factory style too for that same reason
  • Create a proper util which allows for easy addition, editing and so and forth of the IR. For example, a proper util which can find edges. Perhaps also add a reference to the apropriate jump edge linked in the stmt and vice versa? For the util I envision doing something such as Build.new().Integer().create() or Build.new().IllegalStateException().create() or Build.invokevirtual(method).build() or Build.jump(target) or Build.if().jump().build() or Build.if().invokevirtual(method).store().build(). Depending on what we want it to return, we give it multiple choices, making it easier to create obfuscation and stuff
  • Begin implementation of LLVM compiler using the sorta-LLVM style stmt structure we got. We need to override them all and add a LLVM compile method to compile them to LLVM bytecode. Once that's done in the future we'll be able to create a website which runs that shit in LLVM-clang to cross compile on our backend, making it a smooth experience for customers
  • Add proper parameter obfuscation with a properly done seeding system. My idea is that seeds should vary in type instead of being consistent eg one seed will be passed as a double then will be transformed using it's hashcode and stuff.
  • Add a proper invocation resolver which caches everything pre-emptively. Make sure to make it support exclusions and stuff
  • Optimize MapleIR's class heredity construction. Pretty weak sauce rn

Examples

Builder example

Builder
  .invokevirtual(method)        // Invokes the method and adds it to the stack. We have to use the stack value before exiting the builder for a stmt
  .asImplicitInt()              // Converts the builder into an integer builder, allowing us to use arithmetic operations. We could also just make this refer 
                                // to the hashcode function instead if it isn't an integer
  .add()                        // Adds the next value, switches to an Addition builder
    .invokevirtual(method2)     // Pops back a value, switches back to the expression builder
  .condition()                  // Adds a condition, switches to the condition builder
    .ifEqual(target)            
    .ifSmaller(5, target2)                     
    .ifBigger(6, target3)
    .else(target4)              
  .buildStmt()                  // Creates a statement (or statement list) based on the previous instructions

    Cannot use maple-ir dependency.

    I have tried using every version on Jitpack along with the forked version in the Discord. No matter what I use, some methods or classes are missing, such as isNative() and isAbstract() from MethodNode, along with many others. What version of maple-ir should I be using, and where do I get it?

    JSR isnt supported

    Describe the bug This probably should go on the MapleIR repo, but idk.

    To Reproduce Steps to reproduce the behavior:

    1. Obfuscate any jar with a jsr opcode anywhere

    Expected behavior I expect it to obfuscate the jar like normal.

    Screenshots

    MalformedJsonException

    When I tried to obfuscate an application I created, this error occurred and obfuscator froze. I can't upload the jar file itself because of the risk of it being lost, but I can tell you that it is a jar file containing a very large txt file for information.

  • [Bug] Flow obfuscation can skip some blocks in an odd scenario (Most likely due to exceptions)

    [Bug] Flow obfuscation can skip some blocks in an odd scenario (Most likely due to exceptions)

    Sample jar used: AntiHaxerman.jar-out.jar.zip

    Issue persisting with PacketEvents NMSUtil. Origin unknown, supposed to be coming from an exception range (most probable). To investigate. Issue persists without any flow passes inside (hash invalid for some reason????).

    Follow up from #6

    Minor spelling corrections

    Hi, I'm sort of learning how to use GitHub so I thought I would make a pull request with some spelling changes to test it out. I hope this is helpful.

    Exception in thread "main" java.lang.UnsupportedOperationException

    Describe the bug When trying to obfuscate a jar (it is a Minecraft client jar, compiled with all dependencies) I get this error. The application works on another standalone jar file, but not this one.

    To Reproduce Steps to reproduce the behavior:

    1. Try to obfuscate a jar file that might be a minecraft client or a big jar file.

    Expected behavior THe expected outcome was for the file to be obfuscated. However, it throws an error and then stops the obfuscation.

    Screenshots unknown (1)

    Welcome to Skidfuscator 2.0.4

    ๐ŸŽ‰ Changelog

    • โœจ NEW Analytics system based on matomo.org which provides anonymous, safe and open source analytics. This will enormously help me as of right now gauge the amount of users, and in the future perhaps even log the most common missing classes for the creation of a common mappings database. How cool!
    • โœจ Improved obfuscation strength
    • ๐Ÿ›  Began works on the dynamic local system
    • ๐Ÿ“š More documentation to wiki
    • ๐Ÿ› Fixed a bug in which the String encryption would create a -1 size array
    • ๐Ÿ› Fixed a bug in which the String encryption would not compute
    • ๐Ÿ› Fixed a bug in which two congruent types would cause a confliction for the parameter obfuscation

    โœจ New Features

    Have a peek at all the new features available now in Skidfuscator 2.0.3!

    Token Logging Warning

    As of now, several token logging strings, found from various sources, have been blacklisted. We do not tolerate nor condone the spread of malware, and will continuously pursue against fighting it. As of now, the following warning will be displayed:

    Skidfuscator warning against token loggers

    Skidfuscator Mappings

    This update introduces the skidfuscator mappings, which you may find to be automatically generated somewhere on your computer depending on whether or not your libraries folder was specified. Here's an example of what one looks like: Skidfuscator mapping example

    This feature boosts performance by 10x as it simplifies the reading of dependencies down to a single .json file. Pretty fancy ay?

    Welcome to Skidfuscator 2.0

    Lets have a look and what's new, where to get started and so forth.

    ๐Ÿ… Milestones

    Let's reflect on the milestones we've achieved; we've done some amazing things as of recently. It's incredible what this community has been able to achieve in such a short time.

    • Over 250 github stars ๐Ÿ’ฏ
    • Over 230 discord members ๐Ÿค˜
    • Four new core team members โœจ
    • New set of generation changing obfuscation methods ๐Ÿ—ฟ

    ๐ŸŽ‰ Changelog

    • โœจ **NEW** Interprocedural Gen 3 obfuscation (with method parameter changes)
    • โœจ **NEW** Overhauled base to use Enterprise base
    • โœจ **NEW** Exemption system
    • โœจ **NEW** Library system
    • โœจ **NEW** Custom runtime support
    • โœจ **NEW** Range Obfuscation (Exception based obfuscation)
    • โœจ **NEW** Exception Obfuscation
    • โšก๏ธ Vastly improved computation speed
    • ๐Ÿ›  Vastly improved caching
    • ๐Ÿ“š Added wiki
    • ๐Ÿ“š Added documentation to said wiki
    • ๐ŸŽจ Reworked styling
    • ๐ŸŽจ Reworked appearance and style functionality
    • ๐Ÿ› Fixed J11-J18 support
    • ๐Ÿ› Fixed a couple of odd bugs with invoke-dynamics
    • ๐Ÿ› Improved quality of life

    โœจ New Features

    Have a peek at all the new features available now in Skidfuscator 2.0!

    Libraries

    You can now specify a folder where libraries are situated. These are used to establish a hierarchy of classes, something absolutely crucial for our interprocedural obfuscation. This will not be mandated in the future for non-interprocedural obfuscation in the future. You can learn more about this system on our wiki.

    Phantom Libraries (optional)

    In the original 1.0 version, libraries were generated by Phantom by default. In this version, this has been changed to instead become and optional parameter due to the increasing amount of bugs and issues related to JPhantom. Hence, for smaller softwares which only make light use of dependencies, it is possible to use the -ph or --phantom parameter.

    Exclusions

    You can now specify exemptions using Regex. View more about the functionalities of exemptions on our wiki. Here is an example of an exemption configuration:

    method{main}
class{(^joptsimple)|(^net)|(^org)|(^io)|(^protocolsupport)|(^it)|(^shaded)|(^gnu)|(^club)|(^okhttp3)|(^okio)|(^tomp2p)|(^javax)|(^kotlin)|(^com)}
method{weirdMethod} static class{(?s).*}

    Range Obfuscation

    The new range obfuscation makes use of try-catches to break down the control flow graph and make it harder to reverse. As opposed to a traditional code where if A then B, the range obfuscation will transform it to if A then throw Exception then catch Exception then B. This is practical for breaking decompilers such as CFR.
