tiny_tracer
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)
- executed instructions in defined code fragments
Evades some of the known anti-debug and anti-VM techniques
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 3.31.<br/>
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.<br/>
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.
âš™ Usage
📖 Details about the usage you will find on the project's Wiki.<br/>

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.
