Container Residence Discovery Via Proc Virtual FS

Detects potential container discovery via listing of certain kernel features in the "/proc" virtual filesystem

Detection logic

Platform: ESXi IaaS Linux macOS Network Devices Windows
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source product: linux
Log source category: process_creation

Legitimate system administrator usage of these commands
Some container tools or deployments may use these techniques natively to determine how they proceed with execution, and will need to be filtered

Links the source published beside this detection. Reference is the link the source wrote, unmodified. Class is decided by this catalogue from the host and path, not stated by the source. Cited by counts published detections citing the same resource, including this one, and the sources beneath it count the repositories this catalogue ingests, which is not the same as independent research.
