GTIG and Mandiant publish a supply-chain hardening playbook aimed at CI/CD teams

Google's Threat Intelligence Group and Mandiant have released a joint guide on defending against software supply chain compromise, mapping four control categories onto the concrete pipeline levers most teams already own: short-lived tokens, ephemeral runners, package cooldowns and dependency verification.

Docker's fourth horror story revisits the Nx post-install hook that drained CI secrets

The fourth installment of Docker's Coding Agent Horror Stories, published July 28, revisits the August 2025 s1ngularity compromise of the Nx npm package. The lesson for CI/CD teams has nothing to do with coding agents. It is about the post-install hook that ran telemetry.js on every runner that pulled the package.

GitHub Actions freezes suspected-malicious workflow runs until a human signs off

GitHub has flipped Actions into a hold-first posture for workflow runs it flags as potentially malicious on public repositories: the run pauses until a collaborator with write access approves it from an authenticated web session. The change targets a wave of credential-theft attacks that push booby-trapped workflow files with stolen tokens.

Confidential Containers hits CNCF incubation, and every pipeline is on notice

Auditors, OIDC and the trust policy most teams get wrong

A DevOps.com walkthrough by Artur Yolchyan lays out a SOC 2-shaped CI/CD pipeline on GitHub Actions and AWS: multi-account isolation, OIDC federation locked to one repo and branch, and the same container image retagged all the way to production. The interesting part is not the account topology; it is the one line in the trust policy that decides who can talk to your ECR.
