Summary

Malicious code in @galicia-toolkit-nestjs/archetype (npm)

Details

@galicia-toolkit-nestjs/archetype is a dependency confusion package published to npm on 2026-10-09 by the account s4yhii__, targeting the internal @galicia-toolkit-* / @brick-v2 package namespaces with inflated versions (e.g. 999.0.x). Early versions resolve ..dc.oob.s4yhii.com via DNS to beacon the victim's hostname. Later versions run node index.js from a preinstall hook, which loads a bundled native addon (prebuilds/-/metrics.node, Linux and Windows builds). The addon forks a detached process that collects hostname, username, OS/arch, cwd and the full values of CI/cloud secrets from environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, SYSTEM_ACCESSTOKEN, AZURE_DEVOPS_EXT_PAT and others) and sends them as JSON via HTTP POST /native to oob.s4yhii.com:9999.

The package ships a minimal index.js stub that loads a prebuilt native ELF addon at prebuilds/linux-x64/metrics.node on require(). The addon reads CI/CD and cloud credentials from the environment (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, GITHUB_REPOSITORY) along with host identifiers (hostname, uid/pwuid, cwd, uname) and POSTs them as JSON to oob.s4yhii.com via a raw socket (POST /native HTTP/1.0). The addon also imports fork and setsid from libc and detaches as a background process on load, giving the payload a lifetime beyond the Node parent. The scoped name combined with a 999.0.5 version and UNLICENSED metadata fits the dependency-confusion shape intended to beat an internal package's version during resolution, meaning any CI pipeline that resolves this scope will leak long-lived cloud, npm, and GitHub Actions tokens to an attacker-controlled out-of-band host.
