Toolkit - The Essential Toolkit For Reversing, Malware Analysis, And Cracking

This tool compilation is carefully crafted with the purpose of being useful both for the beginners and veterans from the malware analysis world. It has also proven useful for people trying their luck at the cracking underworld.

It's the ideal complement to be used with the manuals from the site, and to play with the numbered theories mirror.

Advantages

To be clear, this pack is thought to be the most complete and robust in existence. Some of the pros are:

1. It contains all the basic (and not so basic) tools that you might need in a real life scenario, be it a simple or a complex one.

2. The pack is integrated with an Universal Updater made by us from scratch. Thanks to that, we get to mantain all the tools in an automated fashion.

3. It's really easy to expand and modify: you just have to update the file bin\updater\tools.ini to integrate the tools you use to the updater, and then add the links for your tools to bin\sendto\sendto, so they appear in the context menus.

4. The installer sets up everything we might need automatically - everything, from the dependencies to the environment variables, and it can even add a scheduled task to update the whole pack of tools weekly.

Installation

1. You can simply download the stable versions from the release section, where you can also find the installer.

2. Once downloaded, you can update the tools with the Universal Updater that we specifically developed for that sole purpose.
   You will find the binary in the folder bin\updater\updater.exe.

Tool set

This toolkit is composed by 98 apps that cover everything we might need to perform reverse engineering and binary/malware analysis.
Every tool has been downloaded from their original/official websites, but we still recommend you to use them with caution, specially those tools whose official pages are forum threads. Always exercise common sense.
You can check the complete list of tools here.

About contributions

Pull Requests are welcome. If you'd want to propose big changes, you should first create an Issue about it, so we all can analyze and discuss it. The tools are compressed with 7-zip, and the format used for nomenclature is {name} - {version}.7z

Tiny_Tracer - A Pin Tool For Tracing API Calls Etc

A Pin Tool for tracing:

• API calls, including parameters of selected functions
• selected instructions: RDTSC, CPUID, INT
• inline system calls, including parameters of selected syscalls
• transition between sections of the traced module (helpful in finding OEP of the packed module)

Bypasses the anti-tracing check based on RDTSC.

Generates a report in a .tag format (which can be loaded into other analysis tools):

RVA;traced event

i.e.

How to build

On Windows

To compile the prepared project you need to use Visual Studio >= 2012. It was tested with Intel Pin 3.28.
Clone this repo into \source\tools that is inside your Pin root directory. Open the project in Visual Studio and build. Detailed description available here.
To build with Intel Pin < 3.26 on Windows, use the appropriate legacy Visual Studio project.

On Linux

For now the support for Linux is experimental. Yet it is possible to build and use Tiny Tracer on Linux as well. Please refer tiny_runner.sh for more information. Detailed description available here.

Usage

 Details about the usage you will find on the project's Wiki.

WARNINGS

• In order for Pin to work correctly, Kernel Debugging must be DISABLED.
• In install32_64 you can find a utility that checks if Kernel Debugger is disabled (kdb_check.exe, source), and it is used by the Tiny Tracer's .bat scripts. This utilty sometimes gets flagged as a malware by Windows Defender (it is a known false positive). If you encounter this issue, you may need to exclude the installation directory from Windows Defender scans.
• Since the version 3.20 Pin has dropped a support for old versions of Windows. If you need to use the tool on Windows < 8, try to compile it with Pin 3.19.

Hidden - Windows Driver With Usermode Interface Which Can Hide Processes, File-System And Registry Objects, Protect Processes And Etc

Hidden has been developed like a solution for reverse engineering and researching tasks. This is a windows driver with a usermode interface which is used for hiding specific environment on your windows machine, like installed RCE programs (ex. procmon, wireshark), vm infrastructure (ex. vmware tools) and etc.

Features

• hide registry keys and values
• hide files and directories
• hide processes (experimental, might be not stable)
• protect specific processes
• exclude specific processes from hiding and protection features
• usermode interface (lib and cli) for working with a driver

and so on

System requirements

Windows Vista and above, x86 and x64

Recommended build environment

• Visual Studio 2019
• Windows Driver Kit 10

Building

Following guide explains how to make a release win32 build

1. Open Hidden.sln using Visual Studio
2. Build Hidden Package project with configurations Release, Win32
3. Open build results folder <ProjectDir>\Release

Installing

1. Disable a digital signature enforcement on a test machine (bcdedit /set TESTSIGNING ON) and reboot it
2. Copy files from <ProjectDir>\Release\Hidden Package to a test machine
3. Right mouse click on Hidden.inf and choose Install
4. Start a driver (sc start hidden)
5. Make sure service is running (sc query hidden)

Important: Keep in mind that the driver bitness have to be the same to an OS bitness

Hiding

A command line tool hiddencli is used for managing a driver. You are able to use it for hiding and unhiding objects, changing a driver state and so on.

To hide a file try the command

hiddencli /hide file c:\Windows\System32\calc.exe

Want to hide a directory? No problems

hiddencli /hide dir "c:\Program Files\VMWare"

Registry key?

hiddencli /hide regkey "HKCU\Software\VMware, Inc."

Maybe a process?

hiddencli /hide pid 2340

By a process image name?

hiddencli /hide image apply:forall c:\Windows\Explorer.EXE

To get a full help just type

hiddencli /help

Bypass-Sandbox-Evasion - Bypass Malware Sandbox Evasion Ram Check

Sandboxes are commonly used to analyze malware. They provide a temporary, isolated, and secure environment in which to observe whether a suspicious file exhibits any malicious behavior. However, malware developers have also developed methods to evade sandboxes and analysis environments. One such method is to perform checks to determine whether the machine the malware is being executed on is being operated by a real user. One such check is the RAM size. If the RAM size is unrealistically small (e.g., 1GB), it may indicate that the machine is a sandbox. If the malware detects a sandbox, it will not execute its true malicious behavior and may appear to be a benign file

Details

• The GetPhysicallyInstalledSystemMemory API retrieves the amount of RAM that is physically installed on the computer from the SMBIOS firmware tables. It takes a PULONGLONG parameter and returns TRUE if the function succeeds, setting the TotalMemoryInKilobytes to a nonzero value. If the function fails, it returns FALSE.

     

• The amount of physical memory retrieved by the GetPhysicallyInstalledSystemMemory function must be equal to or greater than the amount reported by the GlobalMemoryStatusEx function; if it is less, the SMBIOS data is malformed and the function fails with ERROR_INVALID_DATA, Malformed SMBIOS data may indicate a problem with the user's computer .

  

• The register rcx holds the parameter TotalMemoryInKilobytes. To overwrite the jump address of GetPhysicallyInstalledSystemMemory, I use the following opcodes: mov qword ptr ss:[rcx],4193B840. This moves the value 4193B840 (or 1.1 TB) to rcx. Then, the ret instruction is used to pop the return address off the stack and jump to it, Therefore, whenever GetPhysicallyInstalledSystemMemory is called, it will set rcx to the custom value."
