Miasma Attack: Red Hat npm Packages Compromised in June 2026
In June 2026, a sophisticated supply chain attack, dubbed 'Miasma,' compromised over 30 npm packages under the @redhat-cloud-services scope. The attackers infiltrated Red Hat's GitHub Actions OIDC pipeline, injecting a credential-stealing worm into these packages. Upon installation, the malware executed a preinstall script that harvested sensitive information, including GitHub Actions secrets, npm tokens, cloud credentials, Kubernetes tokens, SSH keys, and Git credentials. The stolen data was exfiltrated to attacker-controlled servers, facilitating further propagation of the malware. This incident underscores the escalating threat of supply chain attacks targeting trusted software repositories. The open-sourcing of the Mini Shai-Hulud malware by the cybercriminal group TeamPCP has lowered the barrier for such attacks, enabling a broader range of threat actors to execute similar campaigns. Organizations must enhance their security measures to protect against these evolving threats.
