Supply Chain Compromises Impact Nx Console and GitHub Repositories

<p>CISA is prioritizing the response to multiple emerging software supply chain intrusion campaigns targeting developer ecosystems Continuous Integration/Continuous Development (CI/CD) pipelines. These recent incidents, including the GitHub compromise via a malicious Nx Console Visual Studio Code (VS Code) extension and the “Megalodon” supply chain intrusion campaign, demonstrate how cyber threat actors are abusing tools and processes that support enterprise, cloud, and DevOps environments—specifically CI/CD pipelines, code extensions and workflows.&nbsp;</p> <p>Threat actors leveraged a prior compromise of Nx developer systems to compromise a GitHub employee’s device&nbsp;through a poisoned third-party VS Code extension, resulting in unauthorized access and exfiltration of internal GitHub repositories. The malicious extension version (18.95.0) was distributed through VS Code’s automatic update mechanism, meaning systems with Nx Console previously installed may have received the malicious build without developers taking any manual installation action. GitHub released a <a href="https://github.com/nrwl/nx-console/security/advisories/GHSA-c9j4-9m59-847w" target="_blank">security advisory</a> on this activity, and <a href="https://www.cve.org/CVERecord?id=CVE-2026-48027" target="_blank">CVE-2026-48027</a> has been assigned to the malicious version of Nx Console and added to <a href="https://www.cisa.gov/known-exploited-vulnerabilities-catalog">CISA’s Known Exploited Vulnerabilities (KEV) Catalog</a>.</p> <p>Additionally, in a campaign known as “Megalodon,” a cyber threat actor injected malicious GitHub Action workflows to harvest CI/CD secrets, cloud credentials, and tokens, impacting both development and deployment pipelines in public GitHub repositories.</p> <p>CISA urges organizations to implement the following recommendations to detect and remediate a potential compromise:</p> <ul> <li>Monitor and audit workflow files and contributor activity for suspicious pull re
