{"id":"MAL-2026-17729","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 \u003chostname\u003e.\u003ctag\u003e.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/\u003cplatform\u003e-\u003carch\u003e/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.\n\n---\n_-= Per source details.

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.\n","modified":"2026-10-12T05:30:05.890673979Z","published":"2026-10-09T00:00:00Z","database_specific":{"malicious-packages-origins":[{"modified_time":"2026-10-09T13:37:24Z","sha256":"3a3d8c2302be200e1994c821bdb5fb376867c14b983379bfb7c971d9a201aac6","source":"amazon-inspector","versions":["999.0.2"],"id":"IN-MAL-2026-021298","import_time":"2026-10-09T13:46:17.993464518Z"},{"sha256":"9974df3d2695630f5921c98037f0359ed3948cc0afd0c13d4ad5043819950f15","source":"amazon-inspector","versions":["999.0.3"],"id":"IN-MAL-2026-021282","import_time":"2026-10-09T13:46:16.516505826Z","modified_time":"2026-10-09T13:34:51Z"},{"sha256":"c575dcd065691331dd499c574c56bad03a912f8ee08ceec399835bdd08718758","source":"amazon-inspector","versions":["999.0.1"],"id":"IN-MAL-2026-021317","import_time":"2026-10-09T13:46:19.457821736Z","modified_time":"2026-10-09T13:40:12Z"}],"iocs":{"files":[{"note":"Loader: DNS hostname beacon to *.dc.oob.s4yhii.com, or loads the native exfiltration addon (run via preinstall).","paths":["index.js"],"source":"PACKAGE_ARCHIVE"},{"source":"PACKAGE_ARCHIVE","note":"Native addon that exfiltrates host info and CI/cloud secret env vars to oob.s4yhii.com:9999.","paths":["prebuilds/linux-x64/metrics.node","prebuilds/win32-x64/metrics.node"]}],"urls":["http://oob.s4yhii.com:9999/native"],"domains":["oob.s4yhii.com"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/commons/v/999.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/commons/v/999.0.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/commons/v/999.0.1"},{"type":"WEB","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/commons"}],"affected":[{"package":{"name":"@galicia-toolkit-nestjs-20-lite/commons","ecosystem":"npm","purl":"pkg:npm/%40galicia-toolkit-nestjs-20-lite/commons"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["999.0.2","999.0.3","999.0.1"],"database_specific":{"indicators":{"evidence_files":[{"tlsh":"8272641bb261ce3bc4dc4278015b5ab0b1b25474e77353231b10a1ba3e927485ebaf9a","path":"prebuilds/linux-x64/metrics.node","sha256":"daedefd6a8a02449e29a163a1a92edc0859c0cdb814ec1024b6615fa78bdd375"},{"path":"index.js","sha256":"e51167054446a5e34515cbc25d2512d141edd7854a78ad688f0739baa7541ba7","tlsh":"f0f005dc7fa9b31a52563564d66f010564fbc4f0042cb6c4c009d5d127f0d880a638fc"}],"package_integrity":[{"filename":"commons-999.0.2.tgz","hashes":{"sha1":"0e658b6c6d6be191030f90dd0676f84de53ae28d","sha512_sri":"sha512-VY7eEMnVPU00YdBggbYwnigl8UWFI4PS6Az8fH5kjfwH8niYC+789Dqox8tymapW10ptkSm8LBGWNJGxtCKlQw=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@galicia-toolkit-nestjs-20-lite/commons/MAL-2026-17729.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
