Top 10 Container Security Risks (Docker & K8s)

Over-Privileged Containers (Privileged Mode)

Real World Case Study

A CI/CD pipeline dynamically spun up worker pods using privileged mode to enable build-in-docker (DinD). Attackers compromised a codebase, ran a script inside the CI pipeline, and easily escaped the container by mounting the host's root filesystem `/dev/sda1`, establishing persistent host access.

Precogs AI analyzes Kubernetes manifests and Helm charts, replacing Privileged security contexts with explicit, minimal Pod Security Admission (PSA) restricted policies.

Exposed Docker Daemon Sockets

Real World Case Study

A containerized monitoring tool required access to the Docker socket to collect container metrics. When the monitoring application suffered a command injection flaw, attackers used the mounted socket to instantiate a generic Ubuntu container with host-mounting privileges, bypassing all network isolation.

Precogs AI flags socket mounts and recommends secure, socketless telemetry collection via eBPF or constrained APIs.

Vulnerable Base Images

Real World Case Study

An enterprise deployed hundreds of microservices built on `node:14` (Debian Buster). The base image was riddled with high-severity vulnerabilities including a flaw in `libcurl`. Attackers compromised the container via SSRF and utilized the vulnerable curl version to pivot deeper into the infrastructure.

Precogs AI integrates directly with the Dockerfile generation process, enforcing the use of Distroless base images (Google Distroless / Alpine) that contains zero OS package attack surface.

Kubernetes API Server Exposure

Real World Case Study

A misconfigured EKS cluster left the API server URL public. Although RBAC was enabled, the `system:anonymous` user was inadvertently granted read access to ConfigMaps due to a legacy helm deployment. Attackers enumerated the cluster and extracted database credentials.

Precogs AI ensures cloud infrastructure code definitions bind Kubernetes API endpoints strictly to private VPC CIDR blocks and enforces OIDC SSO authentication.

Insecure Secrets Management in Kubernetes

Real World Case Study

A developer hardcoded an API key into a Deployment YAML. Anyone with read access to the cluster's Deployments via `kubectl get deploy -o yaml` could read it. An attacker who gained read-only access to the cluster immediately stole production API keys and began data exfiltration.

Precogs AI blocks plaintext secrets in IaC repositories and auto-generates integrations for External Secrets Operators (Vault/AWS Secrets Manager).

Excessive Kubernetes RBAC Permissions

Real World Case Study

A log forwarding pod was granted `cluster-admin` privileges to watch all namespaces. When the pod was compromised via a deserialization flaw, the attacker inherited those privileges and deployed ransomware DaemonSets across every node in the 500-node cluster.

Precogs AI analyzes Kubernetes audit logs against declared RBAC policies, instantly generating least-privilege Roles tailored exclusively to the observed API calls of each ServiceAccount.

Unrestricted Network Egress / Lateral Movement

Real World Case Study

A vulnerable PDF rendering microservice was compromised. Because there was no default-deny NetworkPolicy, the compromised pod reached out to an external Command and Control (C2) server, downloaded a cryptominer, and began scanning the internal subnet for exposed Redis instances.

Precogs AI generates granular, zero-trust NetworkPolicies that enforce default-deny egress and ingress, allowing only explicitly mapped microservice dependencies.

Kernel Exploits leading to Container Escapes

Real World Case Study

The 'Dirty Pipe' vulnerability allowed unprivileged container users to overwrite read-only files. Attackers inside a low-privilege container exploited this to overwrite the host's `runc` binary. When the orchestrator restarted the container, the compromised `runc` executed the payload as root on the host.

Precogs AI assesses underlying node kernel versions continuously and enforces Seccomp profiles that severely restrict the syscall attack surface available to containers.

Malicious Container Registries (Typo-squatting)

Real World Case Study

A developer intended to pull the official `postgres:15` image but accidentally typed `postgress:15`. The attacker-controlled image booted the database perfectly but silently initiated a reverse shell back to multiple C2 servers.

Precogs AI enforces Image Signature Validation (e.g., Sigstore/Cosign), ensuring Kubernetes only admits images cryptographically signed by the organization's verified CI pipeline.

Exposed Kubelet API

Real World Case Study

An attacker who gained access to the internal network discovered Port 10250 open across all worker nodes. Without needing Kubernetes API server access, they utilized the Kubelet's `/exec` endpoint to execute a shell inside the core `kube-proxy` container, immediately compromising cluster networking.

Precogs AI audits kubelet configurations ensuring `anonymous-auth=false` and Webhook authorization modes are strictly enforced across managed node groups.
