Overview
Krabs is a C++ library that simplifies interacting with ETW. It allows for any number of traces and providers to be enabled and for client code to register for event notifications from these traces.
Krabs also provides code to simplify parsing generic event data into strongly typed data types.
O365.Security.Native.ETW is a C++ CLI (.NET) wrapper around Krabs. It provides the same functionality as Krabs to .NET applications and is used in production by the ODSP Security team. It's affectionately referred to as Lobsters.
Examples
- Simple examples can be found in the
examples
folder. - Please refer to KrabsExample.md and LobstersExample.md for detailed examples.
- SampleKrabsCSharpExe is a non-trivial example demonstrating how to manage the trace objects.
Important Notes
krabsetw
andO365.Security.Native.ETW
only support x64. No effort has been made to support x86.krabsetw
andO365.Security.Native.ETW
are only supported on Windows 7 or Windows 2008R2 machines and above.- Throwing exceptions in the event handler callback or krabsetw or O365.Security.Native.ETW will cause the trace to stop processing events.
- The call to "start" on the trace object is blocking so thread management may be necessary.
- The Visual Studio solution is krabs\krabs.sln.
NuGet Packages
NuGet packages are available both for the krabsetw C++ headers and the O365.Security.Native.ETW .NET library:
