Samirbous 0c69b63ff2 [New] Kubernetes Secret get or list with Suspicious User Agent (#5974)
* [New] Kubernetes Secret get or list via Scripting or Generic HTTP Client

After obtaining Kubernetes API credentials, adversaries often reach for generic HTTP stacks and scripting runtimes (curl, wget, Python requests, Go’s default client, and similar) instead of kubectl or in-cluster controllers that advertise purpose-built user agents. Those clients are easy to drive from a stolen kubeconfig, a compromised bastion,  or a reverse shell and are commonly used to enumerate or download Secret objects (tokens, registry credentials, TLS material, application keys).

rules/

Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
