Containers
Detection of container escape attempts via bind mounts, privileged containers, or abuse of docker.sock. Defenders may observe anomalous volume mount configurations (e.g., hostPath to / or /proc), unexpected privileged container launches, or use of container administration commands to access host resources. These events typically correlate with subsequent process execution on the host outside of normal container isolation.
docker:daemon
container create/start with privileged flag or host volume mount
kubernetes:apiserver
Pod spec with hostPath or privileged securityContext
[AllowedHostPaths]
List of directories permitted for hostPath volumes. Any access beyond these paths may be suspicious.
[PrivilegedContainerThreshold]
Number of privileged container launches expected in the environment. Exceeding this may indicate adversary behavior.
AN0613
Analytic 0613
Linux
Detection of Linux container escape attempts via syscalls (`unshare`, `keyctl`, `mount`) or process execution outside container namespaces. Defenders may correlate unusual system calls from containerized processes with subsequent process creation on the host or modification of host resources.
auditd:SYSCALL
unshare, mount, keyctl, setns syscalls executed by containerized processes
linux:Sysmon
process creation events linked to container namespaces executing host-level binaries
[SyscallWhitelist]
Expected syscalls by containerized workloads. Deviations may signal an escape attempt.
[TimeWindow]
Defines correlation window (e.g., 60s) between suspicious syscalls and follow-on host process activity.

Analytic 0614
Windows
Detection of Windows container escape attempts by observing processes accessing host directories, symbolic link abuse, or privilege escalation attempts. Defenders may detect anomalous process execution with access to system-level directories outside of container boundaries.
WinEventLog:Security
EventCode=4688
WinEventLog:Sysmon
EventCode=11
[RestrictedHostDirs]
Critical system paths containers should not access (e.g., C:\Windows, C:\ProgramData).
AN0615
Analytic 0615
ESXi
Detection of ESXi escape attempts by monitoring for anomalies in hypervisor logs such as unexpected VM operations, privilege escalation events, or attempts to load malicious kernel modules within the hypervisor environment.
esxi:vmkernel
VM exit/entry anomalies, unexpected hypercalls, or kernel module loading
[AllowedKernelModules]
Modules permitted in the hypervisor. Loading any module outside of this list may indicate compromise.
