Summary: Malicious code in @brick-v2/table (npm)

Details: @brick-v2/table 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 <hostname>.<tag>.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/<platform>-<arch>/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. Source: amazon-inspector (1fdd2bc5b913543c62603b366fb4e1261407f63541e4b01ff7e0052e522523e0) @brick-v2/table presents a trivial Angular-style logger/table shim (forRoot/createLogger/version no-ops) while index.js unconditionally side-loads prebuilds/<platform>-<arch>/metrics.node on require(). The native addon reads credential-shaped environment variables from the installer — 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 — along with hostname, uid, cwd, OS, arch, and release, and POSTs them as JSON over raw HTTP/1.0 to the hardcoded host oob.s4yhii.com at path /native. The native code calls fork+setsid to detach the exfil process so it survives after the host process exits. The destination is not first-party, is not caller-configurable, and the cover-story naming (package name unrelated to behavior, 'metrics.node' filename, _METRICS_PKG env var) disguises the stealer as telemetry. The version number 999.0.2 is implausibly high for the package name, consistent with a dependency-confusion lure.
