sysmon-config | A Sysmon configuration file

This is a forked and modified version of @SwiftOnSecurity's sysmon config.

It started as a is simply copy of the original repository. We merged most of the 30+ open pull requests. Thus we have fixed many of the issues that are still present in the original version and extended the coverage with important new extensions.

Maintainers of this Fork

• Florian Roth @Neo23x0
• Tobias Michalski @humpalum
• Christian Burkard @phantinuss
• Nasreddine Bencherchali @nas_bench

Additional coverage includes

• Cobalt Strike named pipes
• PrinterNightmare
• HiveNightmare

Configs in this Repository

This repo includes the original and two additional configurations

• sysmonconfig-export.xml the original config provided by @SwiftOnSecurity
• sysmonconfig-export-block.xml the original config provided by @SwiftOnSecurity with some basic blocking rules usable since Sysmon v14 (WARNING: use it with care!)
• sysmonconfig-trace.xml a config by @Cyb3rWard0g that logs just everything with a few examples for debugging or threat research purposes

Other Sysmon Configs

• Olaf Hartong's Sysmon Modular - modular Sysmon config for easier maintenance and generation of specific configs

Testing

This configuration is focused on detection coverage. We have only one rather small testing environment to avoid problematic expressions that trigger too often. It is recommended to test the downloaded configuration on a small set of systems in your environment in any case.

Feedback

Since we don't have more than one environment to test the config ourselves, we rely on feedback from the community.

Please report:

1. Expressions that cause a high volume of events
2. Broken configuration elements (typos, wrong conditions)
3. Missing coverage (preferrably as a pull request)

sysmon.exe -accepteula -i sysmonconfig-export.xml
