Yesterday researchers from Palo Alto Networks’ Unit 42 published their discovery of a never-before-seen malware, dubbed Hildegard, that is being used by the TeamTNT threat group to target Kubernetes clusters.

Eventually, they warn, TeamTNT may launch a more large-scale cryptojacking attack via Kubernetes environments or steal data from applications running in Kubernetes clusters.
