The .NET Common Language Runtime (CLR) generates diagnostic logs, crash dumps, and error reports for .NET applications. These logs are stored in user-specific directories and contain information about .NET application crashes, exceptions, and runtime errors.

CLR logs can provide evidence of .NET application failures, crashes, and error conditions that may be relevant to incident investigation or malware analysis.

This collector gathers structured data about clr.

PathRelative path in evidenceOther/CLRv4.0

This collector collects CLR log directories:

  • Users\*\AppData\Local\Microsoft\CLR*

All directories matching the CLR* pattern are collected recursively.

CLR logs can reveal .NET application errors and crashes that may indicate malware behavior or application exploitation. Investigators use this data to analyze .NET application failures, detect malicious .NET assemblies, investigate application crashes, and identify .NET-based malware activity.
