{"id":"MAL-2026-17727","summary":"Malicious code in @galicia-toolkit-nestjs-20/paas (npm)","details":"@galicia-toolkit-nestjs-20/paas 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. Do not edit below this line.=-_\n\n## Source: amazon-inspector (ffdc9c111498bf0f75d014ef58b811df488c9014addfb1ed64f7ab28cf9c11b1)\nOn require('@galicia-toolkit-nestjs-20/paas'), index.js unconditionally loads prebuilds/\u003cplatform\u003e-\u003carch\u003e/metrics.node at module top level inside a try/catch. The shipped ELF 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, and ACTIONS_ID_TOKEN_REQUEST_TOKEN from the process environment, together with hostname, uid, and cwd, and POSTs them as JSON to oob.s4yhii.com over a raw socket (gethostbyname/connect/send, request line 'POST /native HTTP/1.0'). The addon uses fork+setsid to background the exfiltration. The package ships no C/C++ source and no binding.gyp, is self-labeled as a NestJS toolkit, and the only on-load effect of the stub is to execute this opaque native binary. Strings observed inside metrics.node include 'AWS_SECRET_ACCESS_KEY', 'GITHUB_TOKEN', 'NPM_TOKEN', 'ACTIONS_RUNTIME_TOKEN', 'oob.s4yhii.com', and the hardcoded HTTP request format. The scoped name under an organization-shaped '@galicia-toolkit-nestjs-20' namespace combined with the implausibly high 999.0.1 version is consistent with a dependency-confusion lure designed to win resolution against an internal package.\n","modified":"2026-10-12T05:30:05.941522498Z","published":"2026-10-09T00:00:00Z","database_specific":{"malicious-packages-origins":[{"sha256":"311df2d73bdfae1ba853a8206451664e427b291a3aaa9b756b46ab57497ed405","source":"amazon-inspector","versions":["3.0.3"],"id":"IN-MAL-2026-021322","import_time":"2026-10-09T13:46:19.824419869Z","modified_time":"2026-10-09T13:41:02Z"},{"sha256":"51d9743faac8a329d7f1d751f60a2273e230b759816aa7ff1c99fb03fd95e81f","source":"amazon-inspector","versions":["3.0.5"],"id":"IN-MAL-2026-021320","import_time":"2026-10-09T13:46:19.680819053Z","modified_time":"2026-10-09T13:40:43Z"},{"id":"IN-MAL-2026-021293","import_time":"2026-10-09T13:46:17.516036197Z","modified_time":"2026-10-09T13:36:35Z","sha256":"e87fc43cf4df33389d874ea5400cdac35c3616cc053f9db2d901013639dcda6e","source":"amazon-inspector","versions":["3.0.7"]},{"modified_time":"2026-10-09T13:42:15Z","sha256":"ee6e00273ef1e03d45f90b0124e35586a80a8fb82bb94dd2af441c9304489983","source":"amazon-inspector","versions":["3.0.6"],"id":"IN-MAL-2026-021330","import_time":"2026-10-09T13:46:20.426718802Z"},{"import_time":"2026-10-09T13:46:20.193088142Z","modified_time":"2026-10-09T13:41:45Z","sha256":"ffdc9c111498bf0f75d014ef58b811df488c9014addfb1ed64f7ab28cf9c11b1","source":"amazon-inspector","versions":["999.0.1"],"id":"IN-MAL-2026-021327"}],"iocs":{"urls":["http://oob.s4yhii.com:9999/native"],"domains":["oob.s4yhii.com"],"files":[{"paths":["index.js"],"source":"PACKAGE_ARCHIVE","note":"Loader: DNS hostname beacon to *.dc.oob.s4yhii.com, or loads the native exfiltration addon (run via preinstall)."},{"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"]}]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas/v/3.0.3"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas/v/3.0.5"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas/v/3.0.7"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas/v/3.0.6"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas/v/999.0.1"},{"type":"WEB","url":"https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/paas"}],"affected":[{"package":{"name":"@galicia-toolkit-nestjs-20/paas","ecosystem":"npm","purl":"pkg:npm/%40galicia-toolkit-nestjs-20/paas"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"versions":["3.0.3","3.0.5","3.0.7","3.0.6","999.0.1"],"database_specific":{"indicators":{"evidence_files":[{"path":"prebuilds/linux-x64/metrics.node","sha256":"3f8833d49735dfdfe9bdef504bbb53ff069cb48a3953d9af08659d1c5560cf26","tlsh":"cf72775bb361ce3bc4dc4334055b5a70b1b29870e77353231b11a1bb3d927885ebae9a"},{"tlsh":"e3f02ed53fb9b355a1777aa4d55f014668fed0f0141db784c45cc4d026e198909738fc","path":"index.js","sha256":"d0ec250d9c8a6b4aedd2ef3fbe8d8107d7e09d451f580fb39f725ad807339152"},{"path":"src/archetype/package.json","sha256":"343fe5008d888571bd931cf019c7e375a8b79231859981f618e628adb74fba36","tlsh":"d0d02355c4507c5704d50b5c6a788d1156e7cdff450ba49c034fa25491cc9f7356835f"}],"package_integrity":[{"filename":"paas-3.0.3.tgz","hashes":{"sha1":"ffb7699ddb47c997c1daa680fb4f8bb095cf83a3","sha512_sri":"sha512-5sOCZOu3SOlnrLjve0SVYErXr3wKlOaoJr85QQlL4+zrtbCCDLtgnQkpeEGugxUeqNCclxFykhD7l3b8ItsnCQ=="}}]},"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"},{"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","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"},{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@galicia-toolkit-nestjs-20/paas/MAL-2026-17727.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"SafeDep","contact":["https://safedep.io"],"type":"FINDER"}]}
