Summary

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

Details

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

package.json declares a preinstall hook node index.js || true, which require()'s a bundled native addon at prebuilds/-/metrics.node. On N-API registration the addon reads 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, and AZURE_DEVOPS_EXT_PAT, collects hostname/user/cwd, and POSTs the data as JSON to http://oob.s4yhii.com/native. The payload is concealed inside a compiled.node binary named metrics (symbol do_report, cover-story env var _METRICS_PKG, JSON field src:native) with no corresponding C/C++ source shipped; the package otherwise advertises itself as a NestJS commons library, and shipping a native socket-opening module is inconsistent with that purpose. The implausibly high version 999.0.3 on a @...-lite/commons scope is consistent with a dependency-confusion lure targeting an internal package name.
