eBPF allows for introspection of events across entire nodes and is a powerful foundation for collecting data from different workloads on a Kubernetes cluster. This talk will explore step-by-step a cryptocurrency mining attack, showing how it behaves, evolves, and how different stages of the attack can be detected using open source eBPF-based tools.
As a demonstration, a live miner barely detectable using traditional userspace tools will be shown on a pod. Using tools like Cilium’s project Tetragon and leveraging eBPF’s kernel-based network and process-level visibility, malicious behaviors such as suspicious processes and unexpected outbound connections are easily identified. As a result, the detected miner will be blocked, and the cluster defended.
Attendees will leave with ideas for protecting Kubernetes clusters, as well as an understanding of how eBPF-based tools can operate across an entire Kubernetes cluster without any modification to applications or their configuration.
