Detects the removal of a deployment from a Kubernetes cluster.
This could indicate disruptive activity aiming to impact business operations.

Detects creation of a container with a hostPath mount.
A hostPath volume mounts a directory or a file from the node to the container.
Attackers who have permissions to create a new pod in the cluster may create one with a writable hostPath volume and chroot to escape to the underlying node.

Detects the creation of a "privileged" container, an action which could be indicative of a threat actor mounting a container breakout attacks.
A privileged container is a container that can access the host with all of the root capabilities of the host machine. This allows it to view, interact and modify processes, network operations, IPC calls, the file system, mount points, SELinux configurations etc. as the root user on the host.
Various versions of "privileged" containers can be specified, e.g. by setting the securityContext.privileged flag in the resource specification, setting non-standard Linux capabilities, or configuring the hostNetwork/hostPID fields

Detects identities attempting to enumerate their Kubernetes RBAC permissions.
In the early stages of a breach, attackers will aim to list the permissions they have within the compromised environment.
In a Kubernetes cluster, this can be achieved by interacting with the API server, and querying the SelfSubjectAccessReview API via e.g. a "kubectl auth can-i --list" command.
This will enumerate the Role-Based Access Controls (RBAC) rules defining the compromised user's authorization.

Detects remote RPC calls that performs remote DCOM operations. These could be abused for lateral movement via DCOM or WMI.
Detects remote RPC calls to possibly abuse remote encryption service via MS-EFSR
Detects POST requests to the F5 BIG-IP iControl Rest API "bash" endpoint, which allows the execution of commands on the BIG-IP
Detects Octopus Scanner Malware.
Detects file names with specific patterns seen generated and used by tools such as Mimikatz and DSInternals related to exported or stolen DPAPI backup keys and certificates.
Detects the creation of the default output filename used by the wmiexec tool
