MAL-2026-5385

Summary: Malicious code in @0xlr/clerk-auth (npm)

Details: Source: amazon-inspector (2ff421a5ccb412fd8455e89a1b9875b427ed34af12fa4b188ed4418cd8f52a74) On `npm install`, postinstall.js enumerates the entire process environment (Object.keys(process.env).sort().forEach) along with hostname, username, home directory, cwd, argv, and OS metadata, then POSTs the JSON payload over HTTPS to rytxau88zxh61dw6qz4yn19naeg54vsk.oastify.com (a Burp Collaborator subdomain controlled by the attacker). Any secrets present in the installer's environment at install time — CI tokens, NPM_TOKEN, AWS_*, GitHub tokens, etc. — are leaked to the operator of that Collaborator instance. The package itself is hollow: name `@0xlr/clerk-auth` with version `999.0.0` and a description reading 'Placeholder reservation - company should register clerk-auth' is a dependency-confusion lure aimed at organizations that internally reference an unregistered `clerk-auth` package. Source: ghsa-malware (072d9c29e38d3418b3b53542e0d9bac6de02e95946737f9f3f0378f29534d314) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
