Passwordless Kubernetes Image Pulling with Artifact Keeper via ServiceAccount Tokens

Kubernetes 1.34 and later enables kubelet to forward a pod's ServiceAccount token to an external image credential provider plugin, allowing the plugin to exchange it for short-lived read-only credentials from a compatible registry. Artifact Keeper, an open-source Rust-based OCI and package registry, implements an OIDC provider that validates these tokens and issues temporary credentials without requiring imagePullSecrets in manifests. The approach follows zero-trust principles by eliminating long-lived secrets that can leak across namespaces or clusters. A custom credential provider binary handles the token exchange, enforces audience restrictions, and redacts sensitive data from logs. The solution requires specific ClusterRole permissions for nodes, kubelet flags, and registry-side OIDC mappings that bind Kubernetes namespaces to read-only groups. Testing on kind 1.34.3 confirmed successful pulls for authorized ServiceAccounts and clear 401 errors for unauthorized ones when imagePullPolicy is set to Always.

Malicious Code Injected into LiteLLM Open Source AI Package via Supply Chain Attack

The open-source generative AI tool LiteLLM had malicious code inserted into its official distribution packages, enabling credential theft and remote code execution. The compromise affected version 1.107.0 released on October 21, 2026, and was delivered through legitimate channels in a classic software supply chain attack. Seven malicious wheel files were uploaded to PyPI, while official container images on Docker Hub and GitHub Container Registry were also tainted. Security firm JFrog discovered that the malware steals a wide range of secrets including cloud credentials, SSH private keys, browser-stored passwords, development tokens, and AI service API keys from LiteLLM's database. The code also supports execution of externally fetched payloads and abuses Python's startup mechanisms to run even when the application itself is not loaded. This marks the second supply chain incident involving the project in 2026, following a separate event in March.

GhostAction Campaign Compromises 790 GitHub Repositories via Malicious Workflows

Researchers from OpenSourceMalware have identified 790 publicly accessible GitHub repositories containing malicious workflows planted by the GhostAction campaign as of October 9. The campaign abuses trusted maintainer accounts to inject workflows that automatically exfiltrate secrets including AWS access keys and tokens for GitHub, GitLab, Google, Slack, SendGrid, OpenAI, Anthropic, and OpenRouter. Earlier counts by GitGuardian recorded 772 repositories between August 31 and September 30, though the datasets differ and are not cumulative. A separate wave on October 8 impacted 346 repositories linked to two maintainer accounts, including a project belonging to Uber. The malicious workflow runs on code pushes or manual triggers, scans repository files and full Git history for credentials, and sends findings in plaintext to attacker infrastructure. Removing the workflow file does not mitigate exposure, as successful executions already leak credentials and old commits may still contain secrets.
