Description

A fresh wave of the Miasma Mini Shai-Hulud supply chain campaign compromised legitimate npm packages under the @immobiliarelabs scope on June 26, 2026. The attack targeted Backstage plugins used for GitLab integration and LDAP authentication, affecting 22 package versions across multiple releases. The malware employs sophisticated techniques including hidden payloads that bypass standard package reviews, steals developer credentials and CI/CD secrets, and exploits GitHub Actions workflows for propagation. The campaign appears linked to a compromised upstream GitHub Action (codfish/semantic-release-action) and leverages deployment-triggered workflows for execution. Stolen credentials include npm tokens, GitHub tokens, cloud credentials, SSH keys, and various authentication secrets, which are exfiltrated to attacker-controlled repositories for further propagation across the ecosystem.

Technical Analysis

This supply chain attack compromised npm packages under the @immobiliarelabs scope, specifically Backstage plugins used for GitLab integration and LDAP authentication. The malware uses sophisticated evasion techniques including hidden payloads that bypass standard package reviews. It steals a wide range of developer and CI/CD credentials such as npm tokens, GitHub tokens, cloud credentials, and SSH keys. The attack exploits a compromised upstream GitHub Action (codfish/semantic-release-action) and uses deployment-triggered GitHub Actions workflows to propagate within the ecosystem. The stolen credentials are exfiltrated to attacker-controlled repositories, enabling further compromise of developer infrastructure and continuous integration pipelines. No specific affected package versions are provided in the data. There is no indication of known exploits in the wild at this time.

Potential Impact

The attack compromises developer infrastructure by stealing sensitive credentials including npm tokens, GitHub tokens, cloud credentials, and SSH keys. This enables attackers to propagate malware through CI/CD pipelines and GitHub Actions workflows, potentially leading to widespread compromise of software supply chains that rely on the affected npm packages. The campaign undermines trust in the @immobiliarelabs npm packages and Backstage plugins used for GitLab and LDAP integration.

Defensive Guidance

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until official fixes or updates are released, users should audit their use of @immobiliarelabs npm packages, especially Backstage plugins for GitLab and LDAP, and review their CI/CD workflows for signs of compromise. Rotate all potentially exposed credentials including npm tokens, GitHub tokens, cloud credentials, and SSH keys. Monitor for unusual activity in GitHub Actions workflows and consider temporarily disabling or restricting deployment-triggered workflows linked to the compromised packages. Follow updates from the package maintainers and security advisories for official patches or mitigation instructions.
