Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-12507/ (Markdown: https://insights.sbomify.com/MAL-2026-12507/index.md)","id":"MAL-2026-12507","markdown":"https://insights.sbomify.com/MAL-2026-12507/index.md","name":"MAL-2026-12507","record":{"aliases":["GHSA-33x7-6mwq-xg5j","SNYK-JS-SAPAPPGYVERAPPGYVERDESCRIPTORS-18758933"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package declares an `install` lifecycle script that runs `node index.js`, which requires `lib/core.js`; the same module is the package main, so the payload also fires on any `require()` of the package. `lib/core.js` reads the installer's OS username, hostname, and current working-directory basename and encodes them as labels of a DNS subdomain under `oob.sl4x0.xyz`, then issues a `dns.resolve4` lookup — leaking host and user identity to an author-controlled authoritative resolver. Sibling files `lib/b02e30.js` and `lib/6ad264.js` hide the module names (`os`, `dns`, `process`), the property names (`userInfo`, `hostname`, `cwd`, `resolve4`), and the destination host `oob.sl4x0.xyz` as arrays of char-code hex literals reconstructed with `String.fromCharCode` at runtime. The package name `@sapappgyver/appgyver-descriptors` is crafted to visually match SAP's legitimate `@sap/appgyver-*` scope; the repository `github.com/slaxorg/nms-dashboard-js` and author email `research@sl4x0.xyz` have no relation to SAP and align with the exfil domain.\n\nAny computer that has this package installed or running should be considered fully compromised.
