This is a scan tool for Microsoft Windows executables, libraries, drivers and mdumps. Its main objective is to collect the necessary information to facilitate the identification of malicious code within the analyzed files. This tool analyzes, among other things, the PE header and its structure, the content of the sections, the different types of strings, among many other things. It also incorporates a multitude of its own ideas to recognize anomalies in the construction of files and the detection of mechanisms used by current malware. Using the tool is simple, just configure the options in the drop-down panel on the right and drag the samples into 4n4lDetector. Full support: - 32 bits (8086, x86, ARMv7) - 64 bits (AMD64, x86-64, x64, ARMv8) TI and ET Extraction: Alpha AXP, ARM, ARM Thumb-2 (32-bit Thumb), ARM64, EFI Byte Code, EFI Byte Code (EBC), Hitachi SH3, Hitachi SH3, Hitachi SH4, Hitachi SH5, Intel i860, Intel Itanium (IA-64), M32R, MIPS16, MIPS16 with FPU, MIPS R3000, MIPS R4000, MIPS with FPU, MIPS little-endian, MIPS little-endian WCE v2, x64, x86, x86-64. Buttons code: - Buttons colored green are action buttons that open files and folders or are used to interact with the tool's utilities. - The buttons colored in red perform reconfigurations, deletion of data or reset of functional files. - Purple buttons announce the activation of online interactions. - The pink buttons are shortcut buttons that the tool uses as tabs to navigate between different types of utilities. Shortcuts: - [A] Main analysis tab - [W] Analysis tab in modifiable HTML format for report (WebView) - [S] Viewer of strings extracted from the parsed file - [V] Module with the Virustotal report using its API Detections: - PE Information - Unusual Entry Point Position or Code (Algorithms, Anomalous Instructions... ) - Packers - Compilations - Binders/Joiners/Crypters - Architectures - Possible malicious functions - Registry Keys - Files Access - Juicy Words - Anti-VM/Sandbox/Debug - URLs Extractor - Payloads - AV Services - Duplicate Sections - IP/Domains List - Config RAT (Only In Memory Dumps) - Call API By Name - Unusual Chars In Description File (Polymorphic Patterns) - Rich Signature Analyzer - CheckSum Integrity Problem - PE Integrity Check - SQL Queries - Emails - Malicious resources - PE Carve - Exploits - File Rules for Entry Points and more... 😃 Console Options (Analysis to file): - 4n4lDetector.exe Path\App.exe -GUI (Start the graphical interface parsing a file from the console) - 4n4lDetector.exe Path\App.exe -GREMOVE (Remove binary after scan) - 4n4lDetector.exe Path\App.exe -TXT (Parse a file from the console and the output is written to a TXT file) - 4n4lDetector.exe Path\App.exe -HTML (Parse a file from the console and the output is written to HTML file)

Provision: Create a tiny Proxy DLLs for Personal researches. RozDll Vs Fixit: Fixit is a “Static Load Generator”. Handles Pre-Generated List of DLL's that may be work with your Executable or not (same as ByMax). RozDll is a “Dynamic Load Generator”, runs your Executable in Memory, gets a list of Proxy DLL's which your Executable uses in Memory. RozDll Main Features: Generate Fast, Portable & Small Size Proxy/Hijacked DLL. Integrated with x64dbg. You can load the Patched Data directly from x64dbg exported file (*.1337). Dynamic Loading. Function Selection. Deferent Method of patch Options. Encryption: DLL Function Names are Encrypted. This will make it difficult for Anti-Virus to trace generated DLL. Startup Message: You can personalize your work by writing your name and short info/about. This message will appear only at the first run of target executable. Data Extraction: Upload Registry and other filetypes into target PC. Data Verification: Clicking on the 'Magnifier symbol' is mandatory & it will ensure that you entered the correct data. Created on Windows 10 & Visual Studio 2022. It should work on Windows 10 & Windows 11, but not guaranteed to work in Virtual Windows. Tutorial: RozDll_Advanced.mp4 RozDll_Final_Tutorial_(v1.30).mp4

I want to release a new tutorial about the popular theme Themida - WinLicense. So I see there seems to be still some open questions mostly if my older unpack script does not work anymore and the unpacked files to, etc. So this time I decided to create a little video series on how to unpack and deal with a newer protected Themida target manually where my older public script does fail. A friend of mine did protect unpackme's for this and in the tutorial you will see all steps from A-Z to get this unpackme successfully manually unpacked but this is only one example how you can do it, of course. So the tutorial [videos + text tutorial] is very long and has a run-time of more than three hours and of course it will be necessary that you also read the text parts I made at the same time if possible but if you are already a advanced user then you will have it easier than a newbie. So I hope that you have enough patience to work through the whole tutorial. So the main attention I set on all things which happen after normal unpacking so the unpack process is the simplest part and all what comes after is the most interesting part and how to deal with all problems that happen. It's more or less like a live unpack session. I also wrote some small basic little helper scripts which you can also use for other targets to get valuable information if you need. Short summation: Unpacking Exception analysing VM analysing with UV plugin AntiDump's find & fixing & redirecting "after fix method" Testing on other OS My Special Thanks goes to Lostin who made this unpackme and others + OS's tests. (I want to send a thank you to Deathway again for creating this very handy and helpfully UV plugin). So this is all I have to say about the tutorial so far, just watch and read and then try it by yourself. Oh! and by the way I record ten videos and not only one. If something does not work or you have any problems with this tutorial, etc. then ask in the support topic only. Don't send me tons of PM's, OK! Thank you in advance. PS: Oh! and before someone has again something to complain because of my tutorial style [goes to quickly or is bad or whatever] then I just want to say, maybe you're right so normally I don't like to create and write tutorials. This is really not my thing so keep this in your mind.

A simple guide to make your own simple crypter in C++ for PE. In this tutorial shows you how you can create your own stub in Windows platform using VS which is kinda stand alone in the environment and can be attached to other PEs to manipulate the execution of PE. My aim here was to show beginners how such things can be done, and if you learn these basic stuff you can go a few levels higher and create your own costume VM based obfuscation, however you still need to do some heavy lifting yourself. I did this tutorial unfortunately in a little rush, so there are quite a few mistakes here and there but overall the quality of the tutorial is good. I hope it can help you to learn new stuff. Hope to see you again when I have something new to share. Enjoy.

A good understanding of the Portable Executable (PE) file format leads to a good understanding of the operating system. If you know what's in your DLLs and EXEs, you'll be a more knowledgeable programmer. This article, the first of a two-part series, looks at the changes to the PE format that have occurred over the last few years, along with an overview of the format itself. After this update, the author discusses how the PE format fits into applications written for .NET, PE file sections, RVAs, the DataDirectory, and the importing of functions. An appendix includes lists of the relevant image header structures and their descriptions. Note: I have updated the archive to include the second part of this paper and have included the PE32 file used for reference.

The Entry Point is virtualized. 2 Parts of the codes are also virtualized. [Your Mission] Just unpack this file and make it run well without any errors or termination. No devirtualiztion are necessary.

The Hex-Rays Decompiler plugin for better code navigation in RE process. CodeXplorer automates code REconstruction of C++ applications or modern malware like Stuxnet, Flame, Equation, Animal Farm ... Features: Automatic type REconstruction for C++ objects. To be able to reconstruct a type using HexRaysCodeXplorer one needs to select the variable holding pointer to the instance of position independed code or to an object and by right-button mouse click select from the context menu «REconstruct Type» option. Virtual function table identification - automatically identifies references to virtual function tables during type reconstruction. When a reference to a virtual function table is identified the plugin generates a corresponding C-structure. As shown below during reconstructing struct_local_data_storage two virtual function tables were identified and, as a result, two corresponding structures were generated: struct_local_data_storage_VTABLE_0 and struct_local_data_storage_VTABLE_4. C-tree graph visualization – a special tree-like structure representing a decompiled routine in citem_t terms (hexrays.hpp). Useful feature for understanding how the decompiler works. The highlighted graph node corresponds to the current cursor position in the HexRays Pseudocode window Ctree Item View – show ctree representation for highlighted element Extract Types to File – dump all types information (include reconstructed types) into file. Navigation through virtual function calls in HexRays Pseudocode window. After representing C++ objects by C-structures this feature make possible navigation by mouse clicking to the virtual function calls as structure fields Jump to Disasm - small feature for navigate to assembly code into "IDA View window" from current Pseudocode line position. It is help to find a place in assembly code associated with decompiled line. Object Explorer – useful interface for navigation through virtual tables (VTBL) structures. Object Explorer outputs VTBL information into IDA custom view window. The output window is shown by choosing «Object Explorer» option in right-button mouse click context menu Support auto parsing RTTI objects This plugin is recompiled by disauto UPDATE 29.10.2024 Recompiled for IDA Pro v9.0 Windows x86_64

Today I release an unpacker script for Enigma Protector. Maybe you know that I created another unpacker script for Enigma in the past which no-longer works for protected Enigma files greater than 3.70+ and this is the reason why I wrote a new script, Enigma Alternativ Unpacker 1.0. So what is new in this script? This script will unpack your Enigma protected files and dump the used outer virtual machine. This means you do not need to use the DV / Enigma plugin which is used in my other script. Of course the virtual machine will be still virtualized but your unpacked files will work. It is not the best solution but for the moment it is a good "alternativ" and a working solution. Features of the script: ( 1.) Unpacking of ENIGMA 1.90 - 3.130+ ( 2.) RegSheme Bypass & HWID Changer ( 3.) Enigma CheckUp Killer ( 4.) VirtualMemory Dumper 1.90 - 3.x+ & SC Fixer M1 ( 5.) UIF Tool Necessary Sometimes! ( 6.) Enigma Intern Export & VM Scan + Log ( 7.) Improved Import Emulation Fixer ( 8.) Supports Exe & Dll Files [dll at EP!] This new script again covers almost all the protection features of Enigma Protector like my other script but it has been improved and I have added some extra things that you will see when you get to use it. I have created four video tutorials for you where you can see what you have to do in some of the different situations you may experience. Be sure that you "watch the videos" before you use the script to prevent some unnecessary questions where you can already find the answers if you watch them and then read my added text files. I also made an UnpackMe set with six different protected files (watch videos how to unpack all of them). If something does not work for you or if you get any trouble or have any questions then just post a reply on the topic (linked above) to get an answer.

This methods protected with Ultra setting (mutation+virtualization) and complexity none ( for example if complexity setted 22% the output goes 1mb ). Either unpack it, either provide a valid license file.

This tool is designed to rebuild imports for protected/packed Win32 executables. It reconstructs a new Image Import Descriptor (IID), Import Array Table (IAT) and all ASCII module and function names. It can also inject into your output executable, a loader which is able to fill the IAT with real pointers to API or a ripped code from the protector/packer (very useful against emulated API in a thunk). Sorry but this tool is not designed for newbies, you should be familiar a bit with manual unpacking first (some tutorials are easy to find on internet).

Welcome! on this fine day, you have reached CrackZ's Reverse Engineering Page, on the web for 14+ years, despite many censorship attempts. Amongst these pages you will find what is now a very rare commodity on today's commercialised web; a site where you can acquire all the skills you need to become a competent reverse engineer. This site provides information for analysts and protectionists alike, focusing mainly on the protection schemes of Window's software whilst debunking some of the mystery surrounding the sublime art of 'copy protection'. Everything here is yours for free, I hope you will enjoy taking some time to look around. In the last 15 years commercial profit motives have transformed the nature of web information and searching forever, a bitter irony indeed that in our rush to embrace a world of 'free information', more and more is now hidden, treasure troves of free knowledge have been shunned in the stampede for 'e-commerce' gold, snake oil products to this day provide a false sense of security to software authors. This site is fiercely against these trends, but is also realistic in that it will make not one iota of difference. Upon my pages you will find many teachings that should enable you (with a little work) to reverse engineer most of the software you'll ever encounter or need (probably saving you a considerable amount of money). You will find no dubious advertising banners, irritating pop ups, endless loops of smut site referrals or targeted ads, (they couldn't pay me enough to promote their useless products anyway), much of the material here is at a level where little more than a 'willingness to learn' is assumed, of course if you delve a little deeper you will (I hope) find much more.

PE is the native Win32 file format. Every win32 executable (except VxDs and 16-bit DLLs) uses PE file format. 32bit DLLs, COM files, OCX controls, Control Panel Applets (.CPL files) and .NET executables are all PE format. Even NT's kernel mode drivers use PE file format. Why do we need to know about it? 2 main reasons. Adding code to executables (e.g. keygen injection or adding functionality) and manually unpacking executables. With respect to the latter, most shareware nowadays comes "packed" in order to reduce size and to provide an added layer of protection. In a packed executable, the import tables are usually destroyed and data is often encrypted. The packer inserts code to unpack the file in memory upon execution, and then jumps to the original entry point of the file (where the original program actually starts executing). If we manage to dump this memory region after the packer finished unpacking the executable, we still need to fix the sections and import tables before our app will run. How will we do that if we don�t even know what the PE format is? The example executable I have used throughout this text is BASECALC.exe, a very useful app from fravia's site for calculating and converting decimal, hex, binary and octal. It is coded in Borland Delphi 2.0 which makes it ideal as an example to illustrate how Borland compilers leave the OriginalFirstThunks null (more of this later).

Hello everyone! I made a new utility for Team Rept called "REPT Patch Engine". As it name says, this patch engine provides you an easy to use interface to make different types of patch in one single executable. Currently it has 3 types of patching method: Hex Editor (Offset Patch) File Export Registry Patch This utility is made on .NET. I did NOT put any credit of "Created with REPT Patch Engine" because I wanted to make a new patch engine useful. Things to update for next versions: Compare files to see the offset of cracked and original file. DONE! Add custom skin If you need another thing to put on the patch tell me I hope you like it and it could be interesting to use. Fell free to use as you want. LordCoder

Hey there! I made this KeyGenMe because I enjoy playing chess. This challenge is written in .NET and involves some mathematical operations, mixed with a few chess-related twists. Your task is to figure out the logic behind generating a valid serial key based on the username you enter. But be warned—it’s not as simple as just moving a pawn forward ( maybe a hint ) Protection used : None. Goals : 1. Provide valid combination for Username - Serial Key ( Bronze ) 2. Fully KeyGen it - every username with different serial key algorithm ( Silver ) 3. Full KeyGen plus EXPLANATION on what u did and how you figured out everything ( Gold ) Good luck!

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 direct execution. Eclipse Runtime Obfuscation Features in this UnpackMe: Exception-Based Execution Handling – Execution is redirected via VEH, preventing direct tracing. Junk Code Injection – Adds meaningless instructions to mislead disassembly and make static analysis harder. Dynamic Function Relocation – Functions are moved at runtime, disrupting predictable memory access. Control Flow Obfuscation – Execution flow is broken up and redirected via exception handling. Anti-Debugging Protection – The binary throws access violations and illegal instructions to interfere with debuggers. Goals: Unpack the binary (remove VMProtect and restore the original imports). Defeat runtime function relocation and deobfuscate the function logic by resorting the original function code. Reconstruct a clean, runnable (optional) version of the executable with original control flow. Explain how you unpacked and fixed the program, detailing the approach to defeating VEH-based execution and restoring the function code. Bonus points if you can crack the password in the console application demo code. Notes: VMProtect is only used for packing, not virtualization. The main challenge comes from Eclipse’s runtime function relocation and exception-based redirections. Dumping the process isn’t enough, as function code is dynamically obfuscated in memory. The obfuscated functions are exported and named "testCCode", "testCCode2", and "DemoFunction" (this function has the crackme code in it). Would love to see a write-up on defeating the VEH-based execution and restoring the original function code! More information can be found about the Eclipse Runtime Obfuscator project on GitHub. Looking forward to seeing your approaches. Good luck and happy reversing!

In this tutorial we are mainly trying to analyze WIndows internals and learn about Hard disks more. These methods by no means are enough to bypass modern kernel anti cheats. There are lots of ways to track modifications and get DiskSerials later. For example Vanguard anti-cheat will start before most drivers and will track all the HWIDs before even spoofing them with these outdated methods. However, this is a good opportunity to learn the basics and develop more advanced spoofers by merging new methods and tools with it.

Today I release a new created video and text tutorial with a new script. This time everything turns around ExeCryptor. It was not my intention and also unplanned to create a EC tutorial and script but the reason why I did it now was our member "antrobs" had trouble with EC for a very long time, so I just started and now I am finished. Note 1: For all of you who are interested in how to handle EC manually they can check out the long "ExeCryptor Manually Unpack Tutorial" first. There you can see all the steps from A-Z about OEP | IAT | DUMPING | Problem find check & fix - all manually. The tutorial is very long and includes seven longer videos. Most of them are created in real-time with much tracings so it's no tutorial where I explain every single frame with text! The important parts can be read in the different created text files so it's no "newbie friendly" tutorial so keep this in your mind if you are a newbie or if you have no idea, you should have already some RCE prerequisites so that you can follow and understand my steps. Note 2: For all other lazy guys they can watch the script video and can use the script to unpack EC targets after watching it. Note 3: So I know there is already a great EC unpacker tool by RSI which you can use to get your EC files unpacked for most cases and the script is just an alternative which you can use if the EC unpacker tool failed or if you need some more detailed information about your target etc. Like the name already says it's a "basic" version so also if you use it you will have to do some little steps manually [i] like CRC's & Ret patching's but no fear so all information and addresses will be created in an extra LogFile of each target, you just need to change some bytes later that's all and no big deal of course. In the single script video you can see three unpack - fix - other OS check examples, watch it once then you will know what your part is.

WinDbg is a multipurpose debugger for the Microsoft Windows computer operating system, distributed by Microsoft.[1] Debugging is the process of finding and resolving errors in a system; in computing it also includes exploring the internal operation of software as a help to development. It can be used to debug user mode applications, device drivers, and the operating system itself in kernel mode. Like the better-known Visual Studio Debugger it has a graphical user interface (GUI), but is more powerful and has little else in common. WinDbg can be used for debugging kernel-mode memory dumps, created after what is commonly called the Blue Screen of Death which occurs when a bug check is issued.[2] It can also be used to debug user-mode crash dumps. This is known as post-mortem debugging.[3] WinDbg can automatically load debugging symbol files (e.g., PDB files) from a server by matching various criteria (e.g., timestamp, CRC, single or multiprocessor version) via SymSrv (SymSrv.dll),[4] instead of the more time-consuming task of creating a symbol tree for a debugging target environment. If a private symbol server is configured, the symbols can be correlated with the source code for the binary. This eases the burden of debugging problems that have various versions of binaries installed on the debugging target by eliminating the need for finding and installing specific symbols version on the debug host. Microsoft has a public symbol server that has most of the public symbols for Windows 2000 and later versions of Windows (including service packs).[5] Recent versions of WinDbg have been and are being distributed as part of the free Debugging Tools for Windows suite, which shares a common debugging back-end between WinDbg and command line debugger front-ends like KD, CDB, and NTSD. Most commands can be used as is with all the included debugger front-ends.

Most (if not all) of the best hackers, crackers and reverse engineers are also programmers. It is probably impossible to learn RCE well without any knowledge of programming and many of the oldest txt files on cracking would urge the student - "first go away and learn assembler, then come back and read this". This is truer now than ever before as packers and executable protectors use increasingly complex and diverse methods of preventing unpacking, debugging and rebuilding. This has led to cracking groups coding custom tools rather than just relying on debugger, disassembler and tools like ImpREC. It has also led to loaders becoming increasingly popular, a fact echoed by the excellent Cracking with Loaders series from ARTeam. These however are not so easy to understand for beginners without any prior coding knowledge. I have written this tutorial to fill the gap between the complete beginner and the advanced tutorials on loaders, tracers, etc. Similarly, whilst console based apps and tools may be functional they are far from pretty so my second aim was to illustrate how easy it is to create GUI apps in assembler. In the spirit of the assembler programming and reversing communities I have re-used and adapted code from a wide variety of sources which are remembered with full credit and gratitude where possible.

The use of assembler to implement the use of a loader.

Program binaries are commonly held to be an execute-only program form: rigid, lacking in clear structure, complex to extend and difficult to modify. However, there are several benefits to be gained from modifying binaries rather than another program form: the effects of the compiler upon the program are clearly present; binary modification does not require access to source code, which may be unavailable; and users may manipulate programs while they execute, which is impossible with other forms of program modification. In this dissertation, we develop and refine four desired properties of a binary modification toolkit: abstraction, safety, timeliness, and efficiency. By abstraction, we mean that a user should operate in terms of familiar structural representations, such as functions, loops, or basic blocks, instead of directly on instructions. By safety, we mean that modification should preserve the visible behavior of code that was not explicitly modified and the structural validity of the binary as a whole. By timeliness, we mean that a toolkit should allow modification of a binary at any time in its execution continuum, from a file on disk to actively executing code. By efficiency, we mean that modification should impose cost that is both low and proportional to the amount of modified code and the frequency with which it is executed. We then describe three techniques that allow us to achieve these properties. First, we demonstrate that the CFG, an abstraction that represents the binary program’s structure, can also be used to modify this structure and thus the binary as a whole. By leveraging the CFG, we allow users to operate in terms of familiar and natural constructs rather than requiring them to understand the idiosyncrasies of particular instruction sets. Second, we further refine techniques for code replacement, allowing us to modify a program binary at any time in its execution continuum while preserving proportional cost. Third, we present a technique based on a formal understanding of the characteristics of binary code that allows us to modify the structure of the binary without changing its user-visible behavior, even when the binary attempts to detect such modifications.

With 64-bit packers and protectors being released, there is presently a growing need to create new tools to facilitate the manual unpacking process and to make it as trivial as it is now for protected 32-bit executables. I'm proposing two brand-new tools: CHimpREC and CHimpREC-64, allowing the spirit of ImpREC to live on under the best possible compatibility with all the x64 versions of the Windows operating system. This talk is about explaining the inner-workings of coding a 32-bit imports rebuilder and the problems encountered due to the WoW64 environment and Address Space Layout Randomization. Next, is an overview of the differences between the PE and PE32+ formats and their impact on porting CHimpREC to 64-bit. Finally, 2 or 3 short live unpacking sessions with different examples of 64-bit packers and how trivial it has become to deal with them with the help of CHimpREC-64.

Hooking is the practice of re-directing the flow of a program causing it to execute a code-cave or function in an injected module in place of another piece of code. In this tutorial, I will cover a method of hooking known as IAT (Import Address Table) Hooking. IAT Hooking is a 4 step process (I assume you are able to manage to inject the attacking DLL on your own).

In order to obtain and maintain control, kernel malware usually makes persistent control flow modifications (i.e., installing hooks). To avoid detection, malware developers have started to target function pointers in kernel data structures, especially those dynamically allocated from heaps and memory pools. Function pointer modification is stealthy and the attack surface is large; thus, this type of attacks is appealing to malware developers. In this paper, we first conduct a systematic study of this problem, and show that the attack surface is vast, with over 18,000 function pointers (most of them long-lived) existing within the Windows kernel. Moreover, to demonstrate this threat is realistic for closed-source operating systems, we implement two new attacks for Windows by exploiting two function pointers individually. Then, we propose a new proactive hook detection technique, and develop a prototype, called HookScout. Our approach is binary-centric, and thus can generate hook detection policy without access to the OS kernel source code. Our approach is also context-sensitive, and thus can deal with polymorphic data structures. We evaluated HookScout with a set of rootkits which use advanced hooking techniques and show that it detects all of the stealth techniques utilized (including our new attacks). Additionally, we show that our approach is easily deployable, has wide coverage and minimal performance overhead.
