Summary

Malicious code in @galicia-toolkit-nestjs-20-lite/archetype (npm)

Details

@galicia-toolkit-nestjs-20-lite/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.

On npm install, this package runs node index.js || true as a preinstall script. index.js loads a platform-specific native addon from prebuilds/<platform>-<arch>/metrics.node. The Linux and Windows binaries contain the hardcoded host oob.s4yhii.com and a POST /native HTTP/1.0 request line with a JSON template carrying src, pkg, h (hostname), u (username), os, arch, rel, cwd, and e (an environment-variable dictionary). The native code reads a hardcoded set of credential-bearing environment variables including AWS access keys, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, Azure DevOps PAT, and GitHub Actions runtime/ID tokens, and ships them to that host over a raw socket (getaddrinfo/connect/send; WS2_32 on Windows). The Linux variant uses fork+setsid to detach the exfiltration process from the install. The shipped JavaScript is a stub exporting empty forRoot/createLogger, with no real functionality beyond loading the addon. The package name uses a scoped namespace that resembles an internal toolkit and is published at version 999.0.3, a version-overshoot pattern consistent with dependency-confusion targeting private registries.
